Chattanooga Waterproofing Crawl Space

Crawl Spaces in Chattanooga  have been always around, but they became increasingly popular when homeowners started to recognize the improved convenience they have. Compared to the conventional floor setups and concrete floors, crawlspaces granted easy access to the plumbing setup and air ducts, and repairing them became effortless. Moreover, crawlspaces were also used as a storage facility. However, like any good thing in the world, crawlspaces also have its fair share of problems: trapped moisture, vermin, termites, and carpenter ants; invasion of wildlife and accumulation of foul gases to name a few.

I’ve been doing  crawl space encapsulation in Chattanooga for more than two decades now. A good number of correspondences I have addressed were always concerning the foul smell and bad odors that are generated from crawlspaces. It’s imperative to recognize the root causes behind such foul odors and we need to work on strategies that will eliminate the root causes. Crawlspace encapsulation is relatively a new technique which will help you to protect your crawl space, and the health of your family. However, you need to know how to choose the right encapsulation system for your home.

By encapsulating your crawl space, you no longer have to worry about rodents or other wild animals invading your crawl space, moisture accumulation, termites and foul smell that was haunting you for long. A Do-It-Yourself encapsulation kit will undisputedly help you to protect your home from unwanted disasters.

Crawlspace Moisture Control - The Case for Encapsulation

Installing a crawlspace vapor barrier is not rocket science. It is not physically difficult. Whether installing a quality vapor barrier in a vented crawlspace or doing a complete crawlspace encapsulation, it only takes a little time, a little patience and a willingness to crawl around on your hands and knees for a couple of days.

Where to Buy a Crawlspace Vapor Barrier

There are many places to purchase a crawlspace vapor barrier. An on-line search will provide contact information many retailers. And the products they offer vary from inexpensive clear plastic to woven and coated fabrics much like swimming pool liners. The inexpensive liners can also be purchased from many hardware stores and home centers.

What Vapor Barriers Are Available

The inexpensive vapor barriers will do the job but it's been our experience that they tear easily, don't stay in place, and become brittle and crack after four to five years. But they are inexpensive.

The alternative is to spend a couple times more initially and purchase a product with a twenty five year warranty. The reinforced or woven products require no more time to install than the inexpensive shorter-lived products.

The real question is whether an installer wants to spend a couple of days crawling around in a damp crawlspace every four or five years, or wants to spend a little more initially and have an installation that is maintenance-free and will last for decades. Personally, it makes more sense to me to do it right the first time and be done with it.

Installing the Vapor Barrier

Whether doing a full crawlspace encapsulation or simply installing a vapor barrier in a vented crawl space, the installation of all products have a lot in common.

First, the floor needs to be completely covered, with all seams overlapped 6" to 12" and sealed with tape. While duct tape is a wonderful product with countless uses, it does not do a good job sealing the seams of a vapor barrier. A quality, water-proof vinyl tape designed specifically for sealing the seams is recommended.

Wrapping the Crawlspace Piers

Second, the floor material needs to be sealed around all the foundation supports. Whether steel posts or concrete block piers, it is necessary to prevent the migration of water vapor from around the foundation supports. This is usually done by wrapping the piers - sealing the piers with the vapor barrier 6" to 12" up from the floor. This provides a sealed pier to which the floor material can be sealed to using seam tape.

Wrapping the piers can be a little problematic. No safe, nonflammable, nontoxic construction adhesive is effective with the available materials except for a newly developed, patented proprietary wall and pier liner. The vapor barrier is typically applied to the piers using a combination of tape, mastic, caulk, and mechanical fasteners. The mechanical fasteners require that holes be drilled into the piers using a masonry bit and hammer drill. This adds exponentially to the installation labor.

The patented wall and pier liner can be applied to most any surface using a low VOC and nontoxic construction adhesive. Being low VOC and nontoxic, it is nonflammable and safe to use in the confined area of a crawlspace. It can be safely installed in a fraction of the time. It is the only material of its kind and can be ordered from it manufacturer.

Sealing the Crawlspace Walls

Finally, regardless of whether you're installing a vapor barrier in a vented crawlspace or doing a full encapsulation, it is necessary to seal the floor material to the crawlspace walls. Most experts agree that this is a vital step for a well installed barrier or encapsulation.

If installing a vapor barrier, the floor material should be sealed to the wall 6" to 12" above the outside grade. Like wrapping the piers, most companies recommend the tape-caulk-mechanical fastener combination. The mechanical fasteners should be placed every two to three feet long the perimeter of the crawlspace. If taking this approach, be sure to use a respirator as concrete dust can cause severe respiratory problems.

If doing a full encapsulation, the entire wall, a minimum of three inches down from the sill plate to allow for a pest control inspection, should be sealed. Enough floor material can be purchased to extend up the walls or, the method we've found easiest, the wall is covered and sealed with a wall liner and the floor material is sealed to the wall liner using seam tape. Regardless of which method you use, the vapor barrier must be securely attached and sealed to the wall.

The manufacturer of the pier wrap also makes a patented wall liner that attaches to and seals the wall in one simple step. It reduces installation time by several hours. Like the pier wrap, it is available from the manufacturer.

Save Money By Using Crawl Space DIY Kits

For many homeowners, the first thought in their mind when they consider installing a crawl space waterproofing system is, "But I don't go down there! Why on earth would I do that?"

Good question! And there's a great answer. While you probably don't think about your crawl space, and you may have never even seen your crawl space, it's part of your home. What happens to it has surprising effects the rest of your house.

Water can enter into your crawl space in three different ways: through the earth (or concrete) around your home, from a plumbing leak, or through the air entering your crawl space vents. Whether this moisture enters as humidity or as an all-out leak, a wet crawl space means a headache for you. Moisture collects in anything organic - including wood floorboards, support beams, and some types of crawl space insulation. As the wood swells and warps with moisture, there are nasty results: mold, rot, mildew, bacteria, and dust mites.

What you have beneath your house is no longer a crawl space. It's a habitat. The area is filled with humidity, mold spores, and dust mites. All too soon, mice, rats, snakes, and vermin will take up residence- living and dying in the dark, wet area beneath your home. And there's nothing more attractive to a termite colony looking for a new place to live than all that damp, rotting wood!

Ignore the monster lurking below while you can, but remember that even before your rotting floor and support beams are significantly damaged, you're already being affected. Warm air in your home exits the home through your upper levels, and crawl space air is sucked up into your home. As it's pulled up, nothing is stopping the humidity, mold spores, dust mite waste, and odors coming up with it. In the summer, your air conditioners will be working overtime to remove this humidity. During the winter months, cold air vented into the home hammer away at anything it can reach- including the water heater, hot water pipes, and heating ducts.

In a vented crawl space, insulation is a Catch-22. If you don't have crawl space insulation, then there's no line of defense keeping humid summer air and cold winter air away from your floorboards. If you do have crawl space insulation, then moisture and mold can saturate the material, weighing it down and causing it to collapse on to the floor. If it's wet or lying on the ground, what can it do for your home?

The first step to solving a crawl space moisture problem is to remove any standing water issues. Left in your home, it will add humidity to the home, encourage mold and mildew, and bring pests into the room while it stagnates. It simply has to go.

If your crawl space has pooling water at any time, a reliable cast-iron crawl space sump pump is the best option. Water can be directed to the sump pump via a drainage swale, or in some cases, a modern French drain system.

Humidity pours into your house through the crawl space vents, and the damp earth and cement around your home will soak up water like a sponge, releasing water vapor into the area. Cut this problem off at the source by sealing off all crawl space vents and installing a crawl space vapor barrier. Avoid cheap solutions- the kind of product you're looking for should be strong and durable- at least 20 mil thick. A quality crawl space vapor barrier will allow access for you and service workers without tearing your line of defense. Crawl space vapor barriers should also be flexible and resistant to punctures and tears, and a bed of gravel should be laid underneath to allow water to pass underneath.

The crawl space has an integral role towards a home’s overall value as well as the living space above. Most homeowners in Northbriar Chattanooga  don’t think twice about their crawl space unless they have to make repairs to plumbing, heating ducts or house wiring. While often thought of as no more than a storage area, it also has a tremendous impact on the overall indoor air quality of the entire home.

The Best Waterproofing Crawl Space In Northbriar TN

By default, the air quality of a crawl space is typically poor. Mold, mildew, radon gas and poor energy efficiency all create several problems. The air that circulates within it eventually makes its way up through the living space. Scientific studies show that up to 50% of living space air originates from the lowest level of the home. With homeowners more concerned about their home’s indoor air quality, the encapsulating of crawl spaces has become a popular solution for such problems.

A damp crawl space creates a safe harbor for harmful molds, in addition to dust mites, termites and other bugs that can infest the home. The presence of excessive moisture will also create a serious problem with the probability for the wooden structure of a home to deteriorate. Crawl space vents pose a further problem. While believed to be a solution to moisture problems, they, unfortunately, make the problem worse. As it turns out, the vents allow cold air and moisture in, which rises into the living area and therefore decreases the heating efficiency of the entire home.

Another all-too-common problem associated with crawl spaces is radon gas. Though it cannot be seen, smelled or tasted, radon is a radioactive gas that can contribute to poor health, including cancer. Radon gas makes its way through the earth, into the crawl space and the home’s living space. According to the U.S.E.P.A., radon gas is the number one leading cause of lung cancer in non-smokers.

Ignoring these various conditions is not recommended for both long-term health and energy usage. Fully encapsulating a crawl space – by both sealing and insulating – is a fully efficient measure in addressing such problems. It makes sense to maintain and improve the lower level area in order to maximize healthy living conditions and home resale value.

While there are several systems for encapsulating, a zero perm liner system that also insulates and reflects heat provides the most benefits. With a proper floor and wall liner, the area will not only be well insulated but will seal out moisture, bug infestation, and radon gas. Other components to look for in a system include a radon gas-dispersing drain fabric, a radon gas ventilation pipe, and a ceiling heat shield.

A complete system with all of the above components will allow any soil gasses – including radon gas – that naturally occur under the liner system, to wick through the drain fabric and escape out through the ventilation pipe. While improved indoor air quality is the primary benefit of a sealed and insulated crawl space, the homeowner will also appreciate a bright, clean, and dry storage area; the ridding of musty smells; less energy usage; and tax credits. Contractors encapsulating crawl spaces will have more to offer to their clients when they can assure the peace of mind with improved indoor air quality.

Crawl Space Vapor Barrier - A Beginner's Guide On Buying The Right One

Encapsulating a crawl space is a common way to deal with moisture or flooding. It is also an easy way to quickly get control of the air quality in the home and lock out rodents and insects. When you're thinking about "green-ovating" your home, or simply getting control of the moisture or humidity, when you have a crawl space, you must encapsulate.

Encapsulation does a great deal for the crawlspace and for the home above.

What the process is and what it does

The practice of encapsulating or "sealing off" a crawlspace is done to lock out moisture and cut off the connection between moisture, water and the joists of a home. By running a vapor barrier down the walls of a crawlspace to completely cover the floor, you essential separate the outside from the inside of the home.

This vapor barrier will be the flexible membrane between the walls and floor and the rest of the home. A properly designed vapor barrier will limit the transfer of moisture through it, while regulating the speed at which air will naturally pass through. This helps to limit and control the amount of moisture that will find its way into the air space and completely segregate liquid water and direct it to a sump location.

5 helpful tips when having a Vapor Barrier installed in your crawlspace:

1.) Not all vapor barriers are made for this task - careful. There are many products out in the world that claim to be able to fully encapsulate a crawl space. Make sure that your vapor barrier has a low "perm" rate and that it is at least 14mil thick. If you're planning to use the space for storage make sure that a flexible sub-flooring product is also placed on top of the vapor barrier to protect it.

2.) Cover the walls too - all too often contractors forget to also encapsulate the walls of the crawl space when installing a vapor barrier. This can still allow water and moisture into the basement and therefore render the whole project useless. Take care to make sure it's installed properly.

3.) Don't use sprays. - Sealants and sprays aren't designed to be applied on the interior of the basement. They are good in many circumstances as the "first line of defense" but as the last, they can't hold the pressure and moisture trapped in a wall.

4.) Install a sump and a dehumidifier - to totally control the moisture level in the crawl space it's imperative that you have a sump pump and a dehumidifier installed. Moisture will still exist, although not to dangerous levels, but a sump will remove any liquid water your encapsulation traps, and the dehumidifier will deal with any residual moisture that naturally collects in the space.

5.) Look for the right contractor - many of the contractors who specialize in this repair are also in the basement waterproofing business. These contractors, over other general contractors, are preferred because they'll have access to more robust and dependable solutions. They also have the proper training and experience to pull the project off with little effort on your part.

Encapsulating a crawl space will limit moisture and humidity in your cellar and help lower your energy costs. Limiting moisture will help to ensure that any insulation in your floor boards will be working at their peak while keeping the cost of running any air conditioning units to a bare minimum.

Crawl Space Repair Without a Fan or Vent

Most new home owners consider converting the basement into another living space such as a playroom for the kids or a bar for entertaining guests, but never get around to actually bringing their basement finishing ideas to fruition.

This is mainly because the basement is a space that's not immediately accessible or visible to guests, and that is why basement finishing ideas are always placed in the backburner and are looked into only after the major rooms in the house have been taken care of.

However, renovating a basement space doesn't have to be additional expense, especially if the home owner plans to turn it into a useful space. A home office, for instance, would be perfect for the basement. You can draw up basement finishing ideas together with an interior designer on how to maximize the available space and make it conducive for working.

It's also ideal for home office use because it's detached from the noise and the activity that goes on in the rest of the house. Whatever you plan to do with your basement, though, you have to keep in mind some important basement finishing ideas that will save you lots of time, money, and effort.

When working on basement space, or any area to be renovated, for that matter, try to plan your renovation backwards. That is, before you start sketching and asking your interior decorator to look for this and that furniture, draw up a budget that you know you would feel good about.

You can't possibly relish using your newly renovated basement when your basement finishing ideas will cost you an arm and a leg. This is why you need to determine your budget first prior to starting work on anything.

Once you have your budget, you can sit down with your contractor and designer to discuss what you want to get out of the renovation. Let them know what elements you want in that space and let them tell you if it's feasible or not. For instance, adding a toilet and bath is a fantastic basement finishing idea, but it can make a big dent on your budget.

Keep in mind that the things or fixtures you add should be necessary, not just added on a whim. Another practical baseent finishing idea is to create storage spaces. Remember that if you are to use the basement for some other purpose, then you are going to be displacing all the stuff that has been sitting in your basement through the years.

Where would you transfer them? The answer is, in most cases they'll still have to be kept in the basement, so the only great solution would be to construct some ingeniously designed storage spaces. Cabinets and overhead shelves are a must.

Next, go over the basement's electrical wiring, waterproofing, and plumbing. Don't attempt to do these yourself as they can only be handed by experts in the field. Make sure that the team you are getting is dependable and not just some fly-by-night moonlighter. Check their references or ask your friends and relatives to recommend names.

Discuss your basement finishing ideas with the contractor to know if your current heating or cooling setup is adequate to include the basement. If not, you may have to install a cooler or a heater exclusively for your basement space.

Once you have your basement finishing ideas [http://www.homeimprovementbliss.com/basement/basement-waterproofing-a-practical-way-to-save-on-basement-repairs-49] pat down, make sure the place is safe for everyone. Make provisions for fire escapes and see to it that all the doors and door locks are working.

Basement Waterproofing Contractors - Make Sure They're Busy

There are advantages and disadvantages in having a crawl space under your home. Advantages, perhaps, a slightly elevated home may be more attractive than a home on a slab. Plus, you can make repairs and modifications to plumbing, heating, and electrical services.

Disadvantages, a crawl space is an area that is never cleaned. Under the vapor barrier the humidity is always 100% so mold and bacteria are always present. Termiticides, other chemicals, even rodent droppings may be present, and odors and gases that emanate will migrate into the home's living space unless proper ventilation is installed. Whether on a slab or elevated, if radon is present, good ventilation is required.

There are several technologies on the market in regard to moisture control. One is encapsulation, sealing the crawlspace. Though this might lower humidity, it's costly and there is no dilution or replacement of stagnant, poor quality air. Again, if radon is present, ventilation is required.

Another technology is to install a dehumidifier in the crawl space. This can lower humidity, but again will not dilute or replace the stagnant air. Another point to think about is that the dehumidifier will be costly to operate. More importantly, using a dehumidifier requires you to close tightly the crawl space. Thus, the home's living space air quality is going to be lowered because the crawl space air is not diluted and replaced with fresh outdoor air.

Some systems use a dehumidifier control (dehumidistat) to operate a crawl space vent fan. This sounds like it's going in the right direction. However, the technology isn't quite right. Here's why. Suppose the outdoor air is getting worse (wetter). Though the dehumidistat control is in the crawl space, it will quickly recognize this wetter air condition and begin ventilation, even though ventilating is going to make crawl space wetter. Another problem with a dehumidistat control is that most of them are not made for the difficult environment of a crawl space, so their warranties are short, 30 days to 1 year maximum for the dehumidistat.

There is another system that uses special technology different from all the others mentioned above. This special technology makes a comparison of the actual moisture content of both the air inside the crawlspace and the outdoor air. The result is that it pauses and does not ventilate when bringing in outdoor air is going to make the space wetter. Then, as the outdoor air is getting drier and is able to improve the moisture and air quality in the crawlspace, then this ventilator moves a lot of air which dilutes and replaces stagnant air, ultimately improving your home's living space air quality.

This system, called the Smartvent, is made in the USA, is used from Florida to Alaska... San Diego to Nova Scotia.

This system is a proven system, and it is the only system to have undergone a year long test where crawl space humidity averaged 46%. Besides the unique technology this system employs, it also has the longest warranty of all ventilators, five years.

The Three Basic Types of Home Foundations

I recently came across a Consumer Reports article that served as a good reminder to homeowners about some of the home's maintenance issues that are just too important to put off. With today's economy, it is easier to justify holding off on repairing a leaking basement wall crack because it seemingly does not pose an immediate threat, outside of a little inconvenience, of course.

Problems related to the foundation's structural stability or the indoor air quality of the home requires more immediate action; such issues are essentially putting the health and overall safety of the family at risk: not tomorrow, or a year from now, but at this moment.

While bad news for the homeowner, such problems are good for basement waterproofing and foundation repair contractors - the need for their services will always exist. The Consumer Reports article lists a couple of problem issues that the homeowner should be concerned about - the growth of mold and mildew and the formation of cracks in poured foundations. As a business owner who works with the basement waterproofing industry, these are two areas of concern that I am well familiar with.

The growth of mold and mildew can occur inside a home for endless reasons. The most prominent areas are basements and crawl spaces, where excess moisture is a sure bet unless the necessary measures are taken. Concrete walls are prone to the seepage of water vapor - leaking water from cracks in the foundation or the floor adds to the problem. The basement and crawl space provides the ideal environment for trapped moisture to eventually grow into mold spores and mildew.

Concrete cracks in poured foundation walls usually occur as a result of shrinkage or settling around the foundation. Cracks forming as a result of shrinkage in the concrete typically do not pose a structural threat, yet they may cause headaches for the homeowner the second they begin to leak water.

Whether such foundation cracks are structural or not, it is best not to leave them exposed for long, as it relates to the concern of the home's indoor air quality. These cracks, as well as in concrete floors, may provide an opening for soil gases. The infiltration of soil gases, in addition to the growth of mold and mildew can be enough to create an indoor air quality nightmare. The bad air circulating inside the basement and crawl space affects the entire home - 50% of the air circulating throughout the home originates from the home's lowest level.

Concrete cracking is unavoidable. Properly addressing them early on will minimize further problems down the road. Further indoor air quality concerns may also be addressed by implementing the proper waterproofing and sealing techniques throughout the basement and crawl space. There are plenty of qualified contractors throughout the United States and Canada available to service such jobs.

It's reassuring to know that our message is backed up by an objective source such as the Consumer Reports. You view the article at the provided link, http://shopping.yahoo.com/articles/yshoppingarticles/418/5-home-repairs-not-to-ignore/.

5 Helpful Tips For When it is Time to Encapsulate Your Crawl Space

First, it might be quite costly (several thousands of dollars). Second, and much more importantly, the sealing of a crawlspace is likely to degrade the IAQ (Indoor Air Quality) in your living space.

Rather than sealing a crawl space and creating an IAQ problem in the home's living space, there are less expensive methods to manage crawl space humidity. In the United States, the number of those with allergies is rising about 25% per decade, and asthma cases alone have doubled in the last 20 years.

The rise in those having allergies is more common in developed countries, and it is suggested there "must be something in modern, urban life that promotes allergy". Some studies indicate a direct link to the increase in air conditioning and tighter homes. People may save a hundred dollars per year in energy, yet spend thousands on medication and life style change, so, there is no question that the home's IAQ is, by far, the overriding, single most important issue.

Proponents of sealing and not ventilating a crawl space have stated , "venting a crawl space will either add moisture to, or remove moisture from, a crawlspace depending on the moisture content of the ventilation air compared to the desired conditions of the crawl space. Venting with dry air reduces the moisture levels in the crawl space, while venting with moist air contributes moisture". In this respect, such proponents are absolutely right-on correct!

So, even though it might cost a homeowner $6000-$8000, they suggest a closed, sealed crawl space because the possibility of venting with moist air can make the crawl space wetter.

An optimum alternative that might achieve the best outcome could be to ventilate the crawl space but with a ventilation strategy that would know how much water vapor is in the outdoor air and know how much water vapor is in the crawl space air. Armed with that knowledge the ventilator will be able to make an informed decision whether or not ventilation is going to be helpful or hurtful.

It is evident a strategy like this would permit a crawl space to be ventilated, to dilute and replace stagnant air, odors and gases such as radon, yet not bring in wetter air into the crawl space. A strategy like this will be more effective than other ventilation strategies (like a timer or dehumidistat) because it is selective about not bringing in wetter outdoor air, whereas the timer or dehumidistat is not selective.

Returning to the question of sealing the crawl space and using a dehumidifier to control moisture, there is no question that sealing a crawl space and using a sizable dehumidifier will reduce humidity in the crawl space, but, if sealing the crawl space can compromise the home's IAQ, you ought to reconsider.

Here's why.

1. Even if you are able to seal the crawl space well, you will need a sizable dehumidifier. It will need to be set well below a mold threshold limit because other surfaces may be colder. The lower setting is needed to prevent those colder surfaces from exceeding the mold threshold in the now stagnant crawl space.

2. A dehumidifier mentioned in article requires 30 times the power of other technologies.

3. A dehumidifier will need occasional maintenance.

4. When sealing walls and piers, how do you seal completely without creating a hidden path for termites? It means, of course, you can't completely seal it.

5: The crawl space has become a stagnant area, which, of course, is never cleaned, so odors and gases will be there and they will migrate into the living space of the home.

6: Under the vapor barrier it is always 100% relative humidity, so mold and bacteria is going to grow. And the mold and bacteria spores will migrate into the home.

With the home IAQ in mind, it becomes apparent that some sort of ventilation is needed in a crawl space. The ICC code for the usual passive ventilation setup required one sqft of opening for each 150 sqft of crawl space. Further, the ICC code stated that if a vapor barrier was installed over the ground surface only 10% of the venting area was required (ICC 1804.6.3.1). This would mean that only 1 sqft of opening would be needed for a 1500sqft of crawl space. Clearly this code wasn't working, so the ventilation rate was arbitrarily increased, and, now, today some state codes recognize the strategy of comparing inside/outside water vapor.

So, with IAQ being so important, we can define our goal in a crawl space project: remove/replace stagnant crawl space air and extract moisture from the wood mass in the crawl space. This makes a case for mechanical equipment.

Dilution and replacement of crawl space air with fresh, outdoor air is easily understood, but how do you extract moisture from the wood mass in the crawl space? You must reduce the vapor pressure at the surface of the wood, and you may do this by either of two ways. One is by dehumidification, another is to blow air across the wood's surface, better yet, blow drier air across the wood's surface.

So let's get down to the quick of things. From the home's IAQ perspective you should ventilate your crawl space, but using a dehumidifier and venting would be like setting a dehumidifier out on your front lawn, and then paying the electric bills.

A better system would use an intelligent mechanical ventilation system that, (1) keeps the crawl space closed during unfavorable conditions, (2) opens whenever the outdoor air water vapor content will lower humidity in the crawl space, (3) moves a lot of the lower humidity air to extract moisture from the wood mass. The result is, that as you are diluting & replacing stagnant odors & gases, and radon in the crawl space with fresh, outdoor air, you are also extracting moisture from the wood mass.

Further, an intelligent system might perform other functions, such as to not ventilate when it's freezing outside, and, if the crawl space gets too dry, the ventilator could also automatically reverse its strategy to pump moisture into the crawl space to further stabilize wood floors by maintaining the wood in an acceptable range.

There is one inexpensive, automatic ventilator with all the characteristics described above. It's called the Smartvent®.

5 Helpful Tips For When it is Time to Encapsulate Your Crawl Space

A basement is prone to all types of foundation issues like, cracks in the interior and exterior walls, leaks, soil pressure, excessive moisture, seepage and dampness. These problems get worse over time and cause long term damage to your home, if left untreated. In order to enhance the structural integrity of your home, it is very important to take professional help for basement foundation repair. A professional will ensure that the problem is resolved efficiently.

Many properties experience foundation issues at some or the other time and it is important to know how severe the problem is to look for a treatment that offers a permanent solution. A basement foundation repair can be easily done if you have basic information about the ways to handle such repairs. There are various methods of repairing the foundation of a home. If there is some serious damage, it is advisable to take professional help. For general maintenance, you can either go for mortar application or patching repairs.

Some indications which suggest that you should go for basement foundation repair includes:

- Uneven Floors
- Water collection
- Cracks at entry or exit doors
- Doors not closing or opening properly

Cracks are the most common type of foundation maintenance issues. They are usually found in older basements and are caused due to the changes in the soil below the basement. Shallow foundations are more prone to cracks.

How To Clean Cracks

Once you have identified cracks in the foundation, you need to first clean them comprehensively. Cleaning is important as it not only helps in knowing the type of repair required, but also helps in proper application of the adhesive material. You can use a chisel to remove loose fragments from the cracks and then inspect it to find the right repair method.

If the cracks have just begun to show, you can use either hydraulic cement or Portland mortar to seal the cracks. These materials come with easy to follow instructions and can also be used to resolve any visible unevenness along the basement floor.

If your basement foundation is facing standing water problem, the moisture seepage can cause cracks in the drywall. To patch the leaky spots is the most effective solution for dealing with this problem.

To ensure that repeated basement foundation repairs are not needed, the groundwater should be directed away from the foundation.

A professional basement foundation repair company can be hired to repair foundation cracks, basement walls, stabilize the foundation, install foundation guard, repair eroded, bowed or unstable walls and remove mold problems. A strong basement foundation increases the value of your home.

The crawl space has an integral role towards a home’s overall value as well as the living space above. Most homeowners in Glass Farms Chattanooga  don’t think twice about their crawl space unless they have to make repairs to plumbing, heating ducts or house wiring. While often thought of as no more than a storage area, it also has a tremendous impact on the overall indoor air quality of the entire home.

crawlspace waterproofing

The Best Wet Crawl Space In Glass Farms TN

By default, the air quality of a crawl space is typically poor. Mold, mildew, radon gas and poor energy efficiency all create several problems. The air that circulates within it eventually makes its way up through the living space. Scientific studies show that up to 50% of living space air originates from the lowest level of the home. With homeowners more concerned about their home’s indoor air quality, the encapsulating of crawl spaces has become a popular solution for such problems.

A damp crawl space creates a safe harbor for harmful molds, in addition to dust mites, termites and other bugs that can infest the home. The presence of excessive moisture will also create a serious problem with the probability for the wooden structure of a home to deteriorate. Crawl space vents pose a further problem. While believed to be a solution to moisture problems, they, unfortunately, make the problem worse. As it turns out, the vents allow cold air and moisture in, which rises into the living area and therefore decreases the heating efficiency of the entire home.

Another all-too-common problem associated with crawl spaces is radon gas. Though it cannot be seen, smelled or tasted, radon is a radioactive gas that can contribute to poor health, including cancer. Radon gas makes its way through the earth, into the crawl space and the home’s living space. According to the U.S.E.P.A., radon gas is the number one leading cause of lung cancer in non-smokers.

Ignoring these various conditions is not recommended for both long-term health and energy usage. Fully encapsulating a crawl space – by both sealing and insulating – is a fully efficient measure in addressing such problems. It makes sense to maintain and improve the lower level area in order to maximize healthy living conditions and home resale value.

While there are several systems for encapsulating, a zero perm liner system that also insulates and reflects heat provides the most benefits. With a proper floor and wall liner, the area will not only be well insulated but will seal out moisture, bug infestation, and radon gas. Other components to look for in a system include a radon gas-dispersing drain fabric, a radon gas ventilation pipe, and a ceiling heat shield.

A complete system with all of the above components will allow any soil gasses – including radon gas – that naturally occur under the liner system, to wick through the drain fabric and escape out through the ventilation pipe. While improved indoor air quality is the primary benefit of a sealed and insulated crawl space, the homeowner will also appreciate a bright, clean, and dry storage area; the ridding of musty smells; less energy usage; and tax credits. Contractors encapsulating crawl spaces will have more to offer to their clients when they can assure the peace of mind with improved indoor air quality.

Crawl Space Dig Out: How to Turn Your Crawl Space Into a Basement

I've been in the crawl space business for 15 years and I've seen almost every system you could imagine - from spray foams to concrete to thin plastic sheets. Some are better than others, but the only real way to encapsulate the area beneath your home is to install a liner with zero permeability.

What is Zero Perm?

Zero Perm means just that absolutely no water, moisture, radon gas or odors will penetrate through it. Tests have to show 0.000 penetration of Hydrogen gas (the smallest gas molecule) through the membrane. The whole idea of spending the money to encapsulate the crawl space or basement is to STOP water, moisture, radon gas and any unpleasant odors. Liners that are 6, 12 and 20mil thick are NOT Zero Perm and will still let in harmful gasses as well as letting in moisture that will only continue to feed the mold and bugs that try to get in your home.

What Else Should I Look for in a Liner?

If you are going to spend the time & money to install a crawl space liner look for more benefits as well as zero permeability. Look for liners that are

- Energy Star Rated to get a 30% Tax Credit back on your purchase
- R Value of 5 to add insulation & increase your heating/ cooling efficiency
- Reflectivity value of 97% to prevent radiant heat loss
- Class A / Class 1 fire rating

Homeowners all over are finding that improving the homes they have is more cost effective than buying new. Some homeowners like the fact that they can save money by doing the work themselves and some still prefer to have someone else do the installation. Either way, using a Zero Perm, Energy Star Rated encapsulation system is a great way to pre-finish a basement or any area underneath your home.

DIY Basement Foundation Repair

Outlined below are the most common 4 methods I have seen used in installing a vapor barrier. If you talk to different builders, you usually will end up with many different methods of installing a vapor barrier in a crawlspace. Here are the most common:

1. Pea Gravel on top of plastic vapor barrier - This has to be the all time dumbest thing I have ever seen, and yet it is probably one of the most common. I have had builders tell me that the plastic on the ground KEEPS ground water and moisture from coming up from the ground. Now if there is no moisture or water in the soil, this might be possible; but if that was the case there would be no need for the barrier in the first place. So here is the basic idea - ground floor (bottom) - plastic (middle) - 4" pea gravel fill (top). Once the crawl foundation is built, builders install a 4 - 6 mil plastic on the ground and dump about 4" - 6" of pea gravel on top of the plastic. Eventually, what always happens is that water comes in from the walls and the ground floor and ends up on top of the plastic. So what you end up with is a swimming pool liner that holds water in the gravel for prolonged periods of time. Nearly all the water and moisture in the gravel back fill has to evaporate into the structure. Another example of building practices and science turning a blind eye to crawlspaces for decades.

2. Vapor barrier on top of ground floor - By far the most common practice for installing a vapor barrier. A 6 mil polyethylene vapor barrier is placed over any ground floor. Here is the idea - ground floor (bottom) - plastic (top). The ground floor could be river rock, pea gravel, dirt floor, sand, etc. The seams are typically overlapped 6" - 12" and almost never taped. While this will temporarily stop some moisture evaporation, it does not seal out moisture from the internal perimeter wall where most water penetration occurs. Also moisture can come up from the seams, and the plastic is not durable enough to crawl on. It nearly always ends up with many punctures and holes in it.

3. Vapor barrier on bottom of floor joists - This is rarely seen, and usually only home owners attempt this. This is probably the method that accounts for more wood rot than any other method. If you are even thinking of doing this, quit thinking and call a professional to fix your crawlspace. Most crawlspaces are vented and the cooler surfaces such as duct work, pipes, and the floor will condensate in the summer. The plastic will trap the condensation up against the floor structure and mold and wood rot will occur. Good intentions do not always produce good results.

4. Vapor barrier fastened to sill plate - There is a new industry in crawlspace repair that encapsulates crawl spaces. The process of encapsulation is to install a heavy think plastic liner on the floor and up the foundation walls. The plastic liner is fastened and sealed to the foundation wall and all the overlapped seams are taped. Every potential gap or seam in the liner is meticulously sealed to prevent any moisture from evaporating. Then the vents are sealed in the encapsulation system to prevent hot humid air from entering in the summer. There is another system being sold and installed out there being represented as an encapsulation system, but is far from it.

This "other" system is a 6 mil plastic that is ran up the foundation walls and stapled to the sill plate. None of the overlapped seams are taped. It is basically a glorified vapor barrier on top of the ground floor being ran up the walls and stapled to the wood. They seal the vents without properly sealing the moisture from the ground floor or foundation walls. The problem with fastening plastic to the sill plate is that moisture will "wick" up the foundation wall, and moisture will absorb into the sill plate and floor joists. They are giving free access to all the moisture under the liner to rot the sill plates and floor joists. Not to mention that all the moisture will evaporate up through all of the seams that aren't taped and the plastic liner is only 6 mil and eventually will puncture and tear. Be very careful in the contractor you choose to properly encapsulate your crawlspace.

10 Reasons to Encapsulate Your Crawl Space

Crawl space is one of the most fundamental areas in every home which needs to be kept extremely clean. This is the reason why people go for crawl space encapsulation kits, as these liners make your crawl space extremely clean by keeping away insects, water logging and bad odor. However, the market displays numerous encapsulation kits in different qualities.

Good quality encapsulation kits are more expensive than the cheaper ones, but the cheaper ones are much weaker when it comes to quality. Unfortunately, in my extensive experience in this industry, I have noticed that people are attracted to cheaper ones and choose them for their encapsulation. However, they regret later when the whole thing fails to deliver what it promises.

This undoubtedly is the reason why I suggest using DIY encapsulation kits to save a considerable amount of money. How? It is not only the DIY kit that is expensive, but what's more expensive are the labor charges that come along with it. Labor charges have been increasing higher than ever, and this is the reason why it costs you as much as the encapsulation kits itself. However, if you opt for using DIY encapsulation kit you can save a considerable amount of money that you might spend on labor charges.

Moreover, you can also do your encapsulation at the convenience of your time, patience and energy. You do not have to wait for the professional to arrive at your home, analyze your crawl space and then start the job. Sometimes, this may take longer than you even expect it to finish. This undisputedly becomes the reason why people are more open to taking up DIY kit, as this can finish up their crawl space encapsulation as fast as possible.

What's more? Choosing a DIY kit will help you to ascertain the quality of your liner and the credibility it comes with when protecting your home. By choosing this kit you can take your time and choose the one that suits your preferences and is a permanent solution to your problems. If you leave this to the dealer, you cannot be sure on the quality of liners they will be using and the credibility of their service.

By doing the encapsulation yourself you can be sure that you have done it perfectly and can also alter some changes according to your preference. Hiring a professional will not only take your time and money, but may not be as flexible as you may think.

Crawl space DIY kits are readily available in the market and all you need to do is to research a bit on the types available. Remember, to choose a good quality liner because it all depends on the quality of the liner when it comes to completing the protection of your house.

Improving a Home's Indoor Air Quality by Crawl Space Encapsulation

Crawl spaces are proven to be one of the most convenient floor setups because they can provide sufficient space for air conditioning, ventilation and heating systems, but vapor can really destroy your crawl space, and this is where a crawl space vapor barrier can help you.

Too much moisture under your home can be a real headache as this can affect the structure of your home. Mold and mildew not only destroy your crawl space but they can spread to your wooden flooring and carpet too. By installing a crawl space vapor barrier, you are leaving no room for mold and mildew to survive under your home. This way, you can maintain the strength and aesthetics of your home for several years.

A disappointing fact that I have observed is that many homeowners often underestimate the importance of installing moisture controllers and by the time they realize the importance, it will be too late. Termites and molds would have eaten up a good part of their crawl space. Second scenario is even worse: homeowners who find out that their home structure is under serious threat will install a vapor barrier, without ever considering its quality. Apart from wasting a significant amount of money, you will be left with no results because such insulations won't work well more than a few years and in some cases, only a couple of months.

If you do not miss the nitty-gritty of a professional installation, you can lead a healthy life in your home for several decades.

· Measurement: Before buying the barrier, you need to measure the length, width and height of your crawl space. This will give you an estimate on how much barrier sheet you need. It's always a good idea to buy some extra so that you won't run short on materials even if you wasted some sheet.

· Energy Efficiency: There are two benefits in buying energy efficient liner sheet. They will help you to save a good amount on energy bills, which will provide you excellent comfort in your home and the second advantage is the tax benefits. I have noticed that some store owners stress on the cheaper price and mislead their buyers on the long-term benefits of energy efficient sheets. You will be using them for several years and an energy efficient insulation will cut down your energy bills significantly all these years.

· Product Quality: Ideally, sheets with 60mil thickness provide you the best protection. Your sheet should provide you a minimum warranty of 20 years and it should be antimicrobial, rodent proof and termite proof. If you can't see these certifications on the sheets, you most likely are going to face a huge loss.

These are some of the important things to be considered when you are on the lookout for a crawl space vapor barrier. Needless to say, maintaining your home is the best idea compared to buying a new one because you can significantly improve the living quality of your home for a much lower cost. By installing energy efficient barriers with tax benefits, you are also fulfilling your social responsibility of conserving energy.

crawl space conversion

Improving a Home's Indoor Air Quality by Crawl Space Encapsulation

The single best thing you can do to eliminate moisture and odors coming from the crawlspace is to apply a heavy sheet of plastic. Plastic wrap comes in clear or black and in different thicknesses. Purchase either color and with a thickness of at least 6 mil or better yet 10 mil.

Roll out the plastic so that all of the crawlspace floor is completely covered with plastic. When you have to cut the plastic to go around something, be sure to cover the cut with additional plastic or lap the original layer over the cut out. It's OK to use duck tape on the plastic vapor barrier as well. Just be sure to not have any voids in the plastic where moisture and odors can still get through.

The walls of the crawlspace should be covered as well to better eliminate moisture concerns as they can harbor condensation, a major source of moisture issues. Just roll out extra length of plastic so that you can run it up the crawlspace wall and using the stapler, tack along the ledger board located just above the concrete block or poured wall.

If you eliminate odors, moisture from the crawlspace and other undesirable elements coming from the ground beneath your home, your family will be living in a much healthier environment.

Although this task can be accomplished by yourself, it will be much easier if you can get a buddy or helper to go into your crawlspace and aid in the rolling out of the plastic barrier.

6 mil plastic is fine, however, if you can find thicker plastic (greater than 6 mil) then it will be much harder to rip or tear as you move along the crawlspace.

Save Money By Using Crawl Space DIY Kits

First, it might be quite costly (several thousands of dollars). Second, and much more importantly, the sealing of a crawlspace is likely to degrade the IAQ (Indoor Air Quality) in your living space.

Rather than sealing a crawl space and creating an IAQ problem in the home's living space, there are less expensive methods to manage crawl space humidity. In the United States, the number of those with allergies is rising about 25% per decade, and asthma cases alone have doubled in the last 20 years.

The rise in those having allergies is more common in developed countries, and it is suggested there "must be something in modern, urban life that promotes allergy". Some studies indicate a direct link to the increase in air conditioning and tighter homes. People may save a hundred dollars per year in energy, yet spend thousands on medication and life style change, so, there is no question that the home's IAQ is, by far, the overriding, single most important issue.

Proponents of sealing and not ventilating a crawl space have stated , "venting a crawl space will either add moisture to, or remove moisture from, a crawlspace depending on the moisture content of the ventilation air compared to the desired conditions of the crawl space. Venting with dry air reduces the moisture levels in the crawl space, while venting with moist air contributes moisture". In this respect, such proponents are absolutely right-on correct!

So, even though it might cost a homeowner $6000-$8000, they suggest a closed, sealed crawl space because the possibility of venting with moist air can make the crawl space wetter.

An optimum alternative that might achieve the best outcome could be to ventilate the crawl space but with a ventilation strategy that would know how much water vapor is in the outdoor air and know how much water vapor is in the crawl space air. Armed with that knowledge the ventilator will be able to make an informed decision whether or not ventilation is going to be helpful or hurtful.

It is evident a strategy like this would permit a crawl space to be ventilated, to dilute and replace stagnant air, odors and gases such as radon, yet not bring in wetter air into the crawl space. A strategy like this will be more effective than other ventilation strategies (like a timer or dehumidistat) because it is selective about not bringing in wetter outdoor air, whereas the timer or dehumidistat is not selective.

Returning to the question of sealing the crawl space and using a dehumidifier to control moisture, there is no question that sealing a crawl space and using a sizable dehumidifier will reduce humidity in the crawl space, but, if sealing the crawl space can compromise the home's IAQ, you ought to reconsider.

Here's why.

1. Even if you are able to seal the crawl space well, you will need a sizable dehumidifier. It will need to be set well below a mold threshold limit because other surfaces may be colder. The lower setting is needed to prevent those colder surfaces from exceeding the mold threshold in the now stagnant crawl space.

2. A dehumidifier mentioned in article requires 30 times the power of other technologies.

3. A dehumidifier will need occasional maintenance.

4. When sealing walls and piers, how do you seal completely without creating a hidden path for termites? It means, of course, you can't completely seal it.

5: The crawl space has become a stagnant area, which, of course, is never cleaned, so odors and gases will be there and they will migrate into the living space of the home.

6: Under the vapor barrier it is always 100% relative humidity, so mold and bacteria is going to grow. And the mold and bacteria spores will migrate into the home.

With the home IAQ in mind, it becomes apparent that some sort of ventilation is needed in a crawl space. The ICC code for the usual passive ventilation setup required one sqft of opening for each 150 sqft of crawl space. Further, the ICC code stated that if a vapor barrier was installed over the ground surface only 10% of the venting area was required (ICC 1804.6.3.1). This would mean that only 1 sqft of opening would be needed for a 1500sqft of crawl space. Clearly this code wasn't working, so the ventilation rate was arbitrarily increased, and, now, today some state codes recognize the strategy of comparing inside/outside water vapor.

So, with IAQ being so important, we can define our goal in a crawl space project: remove/replace stagnant crawl space air and extract moisture from the wood mass in the crawl space. This makes a case for mechanical equipment.

Dilution and replacement of crawl space air with fresh, outdoor air is easily understood, but how do you extract moisture from the wood mass in the crawl space? You must reduce the vapor pressure at the surface of the wood, and you may do this by either of two ways. One is by dehumidification, another is to blow air across the wood's surface, better yet, blow drier air across the wood's surface.

So let's get down to the quick of things. From the home's IAQ perspective you should ventilate your crawl space, but using a dehumidifier and venting would be like setting a dehumidifier out on your front lawn, and then paying the electric bills.

A better system would use an intelligent mechanical ventilation system that, (1) keeps the crawl space closed during unfavorable conditions, (2) opens whenever the outdoor air water vapor content will lower humidity in the crawl space, (3) moves a lot of the lower humidity air to extract moisture from the wood mass. The result is, that as you are diluting & replacing stagnant odors & gases, and radon in the crawl space with fresh, outdoor air, you are also extracting moisture from the wood mass.

Further, an intelligent system might perform other functions, such as to not ventilate when it's freezing outside, and, if the crawl space gets too dry, the ventilator could also automatically reverse its strategy to pump moisture into the crawl space to further stabilize wood floors by maintaining the wood in an acceptable range.

There is one inexpensive, automatic ventilator with all the characteristics described above. It's called the Smartvent®.

Crawlspace Vapor Barrier Mythbusters

Encapsulating a crawl space is a common way to deal with moisture or flooding. It is also an easy way to quickly get control of the air quality in the home and lock out rodents and insects. When you're thinking about "green-ovating" your home, or simply getting control of the moisture or humidity, when you have a crawl space, you must encapsulate.

Encapsulation does a great deal for the crawlspace and for the home above.

What the process is and what it does

The practice of encapsulating or "sealing off" a crawlspace is done to lock out moisture and cut off the connection between moisture, water and the joists of a home. By running a vapor barrier down the walls of a crawlspace to completely cover the floor, you essential separate the outside from the inside of the home.

This vapor barrier will be the flexible membrane between the walls and floor and the rest of the home. A properly designed vapor barrier will limit the transfer of moisture through it, while regulating the speed at which air will naturally pass through. This helps to limit and control the amount of moisture that will find its way into the air space and completely segregate liquid water and direct it to a sump location.

5 helpful tips when having a Vapor Barrier installed in your crawlspace:

1.) Not all vapor barriers are made for this task - careful. There are many products out in the world that claim to be able to fully encapsulate a crawl space. Make sure that your vapor barrier has a low "perm" rate and that it is at least 14mil thick. If you're planning to use the space for storage make sure that a flexible sub-flooring product is also placed on top of the vapor barrier to protect it.

2.) Cover the walls too - all too often contractors forget to also encapsulate the walls of the crawl space when installing a vapor barrier. This can still allow water and moisture into the basement and therefore render the whole project useless. Take care to make sure it's installed properly.

3.) Don't use sprays. - Sealants and sprays aren't designed to be applied on the interior of the basement. They are good in many circumstances as the "first line of defense" but as the last, they can't hold the pressure and moisture trapped in a wall.

4.) Install a sump and a dehumidifier - to totally control the moisture level in the crawl space it's imperative that you have a sump pump and a dehumidifier installed. Moisture will still exist, although not to dangerous levels, but a sump will remove any liquid water your encapsulation traps, and the dehumidifier will deal with any residual moisture that naturally collects in the space.

5.) Look for the right contractor - many of the contractors who specialize in this repair are also in the basement waterproofing business. These contractors, over other general contractors, are preferred because they'll have access to more robust and dependable solutions. They also have the proper training and experience to pull the project off with little effort on your part.

Encapsulating a crawl space will limit moisture and humidity in your cellar and help lower your energy costs. Limiting moisture will help to ensure that any insulation in your floor boards will be working at their peak while keeping the cost of running any air conditioning units to a bare minimum.

The crawl space has an integral role towards a home’s overall value as well as the living space above. Most homeowners in Missionary Ridge Chattanooga  don’t think twice about their crawl space unless they have to make repairs to plumbing, heating ducts or house wiring. While often thought of as no more than a storage area, it also has a tremendous impact on the overall indoor air quality of the entire home.

The Best Crawl Space Remediation In Missionary Ridge TN

By default, the air quality of a crawl space is typically poor. Mold, mildew, radon gas and poor energy efficiency all create several problems. The air that circulates within it eventually makes its way up through the living space. Scientific studies show that up to 50% of living space air originates from the lowest level of the home. With homeowners more concerned about their home’s indoor air quality, the encapsulating of crawl spaces has become a popular solution for such problems.

A damp crawl space creates a safe harbor for harmful molds, in addition to dust mites, termites and other bugs that can infest the home. The presence of excessive moisture will also create a serious problem with the probability for the wooden structure of a home to deteriorate. Crawl space vents pose a further problem. While believed to be a solution to moisture problems, they, unfortunately, make the problem worse. As it turns out, the vents allow cold air and moisture in, which rises into the living area and therefore decreases the heating efficiency of the entire home.

Another all-too-common problem associated with crawl spaces is radon gas. Though it cannot be seen, smelled or tasted, radon is a radioactive gas that can contribute to poor health, including cancer. Radon gas makes its way through the earth, into the crawl space and the home’s living space. According to the U.S.E.P.A., radon gas is the number one leading cause of lung cancer in non-smokers.

Ignoring these various conditions is not recommended for both long-term health and energy usage. Fully encapsulating a crawl space – by both sealing and insulating – is a fully efficient measure in addressing such problems. It makes sense to maintain and improve the lower level area in order to maximize healthy living conditions and home resale value.

While there are several systems for encapsulating, a zero perm liner system that also insulates and reflects heat provides the most benefits. With a proper floor and wall liner, the area will not only be well insulated but will seal out moisture, bug infestation, and radon gas. Other components to look for in a system include a radon gas-dispersing drain fabric, a radon gas ventilation pipe, and a ceiling heat shield.

A complete system with all of the above components will allow any soil gasses – including radon gas – that naturally occur under the liner system, to wick through the drain fabric and escape out through the ventilation pipe. While improved indoor air quality is the primary benefit of a sealed and insulated crawl space, the homeowner will also appreciate a bright, clean, and dry storage area; the ridding of musty smells; less energy usage; and tax credits. Contractors encapsulating crawl spaces will have more to offer to their clients when they can assure the peace of mind with improved indoor air quality.

5 Reasons Why Basement Waterproofing is Essential

Crawl spaces are inherently dirty smelly places that can contain all types of unwanted odors from mold & mildew to urine & feces. Some areas of the country can even have soil underneath the home with odorless, harmful gases like radon gas. I'm a big believer that the best long-term solution to solve these problems is to encapsulate the air underneath the home with a liner system. It is a inherently impossible to keep rodents, bugs and mold out of the area underneath the home since the soil is exposed - but it is relatively simple to create a barrier between the home and crawl space the keep out all these unwanted nuisances.

I had a very nice lady write me the other day telling me about this house she had just purchased that formerly had many cats living in the crawl space and they left behind the smell of a giant litter box underneath her home. The odors were coming up through the wooden floor and creating a very fowl smell in the house. She told me she tried all different solutions: spreading baking soda, spraying an enzyme treatment originally intended for carpets & laying down new top soil - needless to say none worked. I wrote her back, apologized for her wasted time and suggested that she treat her crawl space like a wild beast that you can't defeat, only contain. She took my advise, installed a crawl space encapsulation system and the smells immediately went away.

Permeability Rating

Encapsulation systems are rated by permeability - 0.000 is the best, normal plastic is 0.01 and wood is 0.2. To stop all smells, moisture and gases look for an encapsulation liner system with a 0.000 permeability rating. A zero perm liner will also completely weatherize the crawl space and save on energy bills since the outside air won't be able to leak into the home.

Thin Liners Don't Encapsulate the Crawl Space

I can't tell you how many times I've received a call or been sent an email from a homeowner telling me how they went to Home Depot, bought a liner system as thin as a trash bag, spent an entire weekend installing it then didn't solve their problem. Cheap store bought liners are typically 6-12 mil, 0.01 permeability and even new they don't stop gases like Radon - they are also easily chewed through by bugs and rodents leaving the crawl space a year later leaking air like a sieve.

What to Look for

40 - 60 mil thickness, 0.000 permeability and antimicrobial so mildew can't grow on the liner. Encapsulation systems don't need a contractor to install (although trust me they won't tell you that). Look for the Energy Star Rated logo.

Crawl Space Vapor Barrier Basics

Crawl Spaces have been always around, but they became increasingly popular when homeowners started to recognize the improved convenience they have. Compared to the conventional floor setups and concrete floors, crawlspaces granted easy access to the plumbing setup and air ducts, and repairing them became effortless. Moreover, crawlspaces were also used as a storage facility. However, like any good thing in the world, crawlspaces also have its fair share of problems: trapped moisture, vermin, termites, and carpenter ants; invasion of wildlife and accumulation of foul gases to name a few.

I've been doing crawl space encapsulation business for more than two decades now. A good number of correspondences I have addressed were always concerning the foul smell and bad odors that are generated from crawlspaces. It's imperative to recognize the root causes behind such foul odors and we need to work on strategies that will eliminate the root causes. Crawlspace encapsulation is relatively a new technique which will help you to protect your crawl space, and the health of your family. However, you need to know how to choose the right encapsulation system for your home.

By encapsulating your crawl space, you no longer have to worry about rodents or other wild animals invading your crawl space, moisture accumulation, termites and foul smell that was haunting you for long. A Do-It-Yourself encapsulation kit will undisputedly help you to protect your home from unwanted disasters.

Choosing the Right Crawl Space Encapsulation System: Things to Look For:

There are four potential threats for your crawl space: mold, water, rodents and other animals. Foul smell is a result of all these elements. Your crawl space is the natural source of fresh air but when odor is generated in this area, the fresh air entering your home will also be affected. By eliminating the root causes of odor, you can significantly improve the air quality in your home.

  • Liner: I receive several phone calls from disappointed customers who spent their hard-earned money on thin liners because some store owner advised them to do so. However, any liner material without 0.000 permeability and at least 20mil thickness won't help you to encapsulate the system and prevent water and radon gas entering your home.
  • Water: You need a waterproof encapsulation because this will help you to prevent rain water or any other source of running water entering your crawlspace. Moreover, this will also help you to bring down the moisture level, which is a good initiative in making your crawl space unsuitable for rodents and mold.
  • Dehumidifier: If you install the proper liner system, the need for a dehumidifier is greatly reduced as the purpose of removing moisture. The reason being, that a proper liner system will stop the water or moisture before it gets into the home or crawlspace, thus eliminating the need for a dehumidifier.
  • Mold Neutralizer: Dehumidifiers can prevent mold growth to a large extent, but mold neutralizer destroys bacteria, algae and mold and also prevents their future growth.

These are some important factors to be considered when installing an encapsulation system for your home. You also need to consider the warranty & price offered by your store owner. Maintaining your home can be expensive, but by investing in professional encapsulating systems that will protect your home for several decades, you're making a wise investment.

A Closed, Sealed Crawlspace - What a Really Bad Idea

Outlined below are the most common 4 methods I have seen used in installing a vapor barrier. If you talk to different builders, you usually will end up with many different methods of installing a vapor barrier in a crawlspace. Here are the most common:

1. Pea Gravel on top of plastic vapor barrier - This has to be the all time dumbest thing I have ever seen, and yet it is probably one of the most common. I have had builders tell me that the plastic on the ground KEEPS ground water and moisture from coming up from the ground. Now if there is no moisture or water in the soil, this might be possible; but if that was the case there would be no need for the barrier in the first place. So here is the basic idea - ground floor (bottom) - plastic (middle) - 4" pea gravel fill (top). Once the crawl foundation is built, builders install a 4 - 6 mil plastic on the ground and dump about 4" - 6" of pea gravel on top of the plastic. Eventually, what always happens is that water comes in from the walls and the ground floor and ends up on top of the plastic. So what you end up with is a swimming pool liner that holds water in the gravel for prolonged periods of time. Nearly all the water and moisture in the gravel back fill has to evaporate into the structure. Another example of building practices and science turning a blind eye to crawlspaces for decades.

2. Vapor barrier on top of ground floor - By far the most common practice for installing a vapor barrier. A 6 mil polyethylene vapor barrier is placed over any ground floor. Here is the idea - ground floor (bottom) - plastic (top). The ground floor could be river rock, pea gravel, dirt floor, sand, etc. The seams are typically overlapped 6" - 12" and almost never taped. While this will temporarily stop some moisture evaporation, it does not seal out moisture from the internal perimeter wall where most water penetration occurs. Also moisture can come up from the seams, and the plastic is not durable enough to crawl on. It nearly always ends up with many punctures and holes in it.

3. Vapor barrier on bottom of floor joists - This is rarely seen, and usually only home owners attempt this. This is probably the method that accounts for more wood rot than any other method. If you are even thinking of doing this, quit thinking and call a professional to fix your crawlspace. Most crawlspaces are vented and the cooler surfaces such as duct work, pipes, and the floor will condensate in the summer. The plastic will trap the condensation up against the floor structure and mold and wood rot will occur. Good intentions do not always produce good results.

4. Vapor barrier fastened to sill plate - There is a new industry in crawlspace repair that encapsulates crawl spaces. The process of encapsulation is to install a heavy think plastic liner on the floor and up the foundation walls. The plastic liner is fastened and sealed to the foundation wall and all the overlapped seams are taped. Every potential gap or seam in the liner is meticulously sealed to prevent any moisture from evaporating. Then the vents are sealed in the encapsulation system to prevent hot humid air from entering in the summer. There is another system being sold and installed out there being represented as an encapsulation system, but is far from it.

This "other" system is a 6 mil plastic that is ran up the foundation walls and stapled to the sill plate. None of the overlapped seams are taped. It is basically a glorified vapor barrier on top of the ground floor being ran up the walls and stapled to the wood. They seal the vents without properly sealing the moisture from the ground floor or foundation walls. The problem with fastening plastic to the sill plate is that moisture will "wick" up the foundation wall, and moisture will absorb into the sill plate and floor joists. They are giving free access to all the moisture under the liner to rot the sill plates and floor joists. Not to mention that all the moisture will evaporate up through all of the seams that aren't taped and the plastic liner is only 6 mil and eventually will puncture and tear. Be very careful in the contractor you choose to properly encapsulate your crawlspace.
