Tennessee clean crawl space

Crawl Spaces in Tennessee  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 Tennessee 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.

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®.

The foundation of your house depends on a strong basement. Basement waterproofing prevents water from penetrating into the basement area Waterproofing your basement is mandatory or else it could lead to structural damages and collapsing drywall.

Given below are 5 reasons why basement waterproofing is essential:

" Structural damage: Water seepage is very common problem in basements; especially if you live in wet areas with moist soil. If you do not take proper preventive measures for this problem then it could lead to structural damages to your property. You find seepage mainly in the corners where the wall meets the floor. This process is typically slow and won't show immediate consequences but if ignored then it could cause major damages such as bowed walls and cracked foundation. Basement waterproofing is very important to treat wet basements. Timely preventions can save you from disastrous structural damages.

" Infestations: If you live in an area where there are black molds, then it becomes absolutely essential to waterproof your basement. Damp areas are a breeding ground for waterborne contaminants such as black mold. All kinds of mold can grow between walls and under padding of wet carpets; the worst kinds are the black molds. It is very toxic and can cause death. If basement waterproofing is not done in time them these infestations keep breeding in the wet areas which can cause major health hazards. You may even have to abandon the house if the professionals are not able to take care of the infestations.

" Natural calamities: If you live in an area where there is heavy rainfall or in hurricane areas, basement waterproofing becomes very essential. These areas are prone to flooding; as a result, water is very likely to enter the basement. Rainwater can penetrate through cracks in the wall causing seepage. Also when flood water collects around the foundation walls, water collects in small pockets in the soil next to the foundation and starts forming hydrostatic pressure. Over the time this pressure increases until the water is pushed through the wall. Thus basement waterproofing becomes necessary in such areas.

" Damage to property: Most of us keep a lot of stuff in the basement like furniture, books, equipments, etc. sometimes there are workshops or even wine cellars down in the basement. But if the basement is not waterproofed then water seepage can cause a lot of damage to your property. Wooden furniture rots when it gets damp. Expensive items could be damaged due to dampness. It you plan to use your basement for important purposes then it becomes even more essential to waterproof your basement.

" Sloping and grading: It's important to know if the ground around your house is sloping away from your foundation. The soil outside should meet the walls; if it doesn't then the water can penetrate between the gaps. In this case you have to hire a professional grader to help slope the ground downhill and away from your house. But as preventive measures it is best to waterproof your basement just in case you do not detect the sloping around your house instantly.

Basement waterproofing can be expensive but it's worth the cost to prevent you from irreparable damages in the future.

The crawl space has an integral role towards a home’s overall value as well as the living space above. Most homeowners in Tennessee Tennessee  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.

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 Supports

1) Lower your energy costs: A crawl space encapsulation insulates the walls of your crawl space and conditions the air under your home. This results in a 10% to 20% annual savings on your power bill. Encapsulation is one of the few home repairs that pay for itself!

2) Increased home comfort: By conditioning the air in your crawl space your floors will not be cold in the wintertime. This is especially nice for hardwood floors and tile bathrooms. It also keeps your home from feeling humid and stuffy in the summertime.

3) No more musty odors: A crawl space encapsulation eliminates moisture under your home. This means no musty odors being pumped into your home through the air conditioning unit.

4) Increase the air quality of your home: By eliminating moisture under the house, you are no longer getting humid unconditioned air into your home. Encapsulation promotes air circulation throughout the home.. If your air conditioner is located under the house, it is no longer pumping mold spores throughout the home.

5) Air Conditioner lasts longer: Another way encapsulation saves you money is by improving the longevity of your heating and cooling equipment. Humidity increases the load on your air conditioner and causes trunk lines and air ducts to rust.

6) Minimize Repairs: Crawl space encapsulation eliminates moisture under your home. This moisture is the source of many problems from insulation damage, mold and mildew outbreaks, structural damage, and equipment damage from rust.

7) Eliminate insect infestations: By reducing moisture you eliminate a key ingredient that insects such as termites need to survive. No longer will your crawl space be a conducive condition to harbor ugly creepy crawlies in your home.

8) Extra storage space: Most people do not store much in the crawl space because it gets damp, rusts and damages about everything. An encapsulated crawl space becomes a moisture free environment that is perfect for storing anything and everything. Adding 1000 sq ft to 2000 sq ft of storage space always helps.

9) Increase the value of your home: An encapsulation system greatly increases the value of your home. It also makes your home easier to sell. Your home has no moisture issues for the home inspector to find and you have proof of energy efficiency and the lower energy bills your home produces.

10) Tax incentives and rebates: The federal government offers tax rebates for insulation products that improve the energy consumption of you home. Local power companies sometimes offer rebates on your power bill to improve the energy efficiency of your home.

Crawlspace Vapor Barrier Mythbusters

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.
