Knoxville Crawl Space Remediation

Crawl Spaces in Knoxville  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.

cost to encapsulate crawl space

I’ve been doing  crawl space encapsulation in Knoxville 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.

Addressing Moisture, Mold and Radon Gas in Basements and Crawl Spaces With Application of a Deep-Pen

There are three basic types of foundations in use today in the construction of a home.

Slab Foundations

A slab foundation is a foundation built directly on the soil with no basement or crawl space. Slab foundations are common in areas where soil conditions are not suitable for a basement, and are the most common foundation found in warmer areas such as Florida, Arizona, California and Texas, or anywhere where the depth between the soil and stable underlying rock is very shallow. Slabs are the quickest and cheapest foundation because they require less labor, skill and materials cost. They consist of a concrete slab that is typically 6 to 8 inches thick. Embedded within the slab is a grid of supporting ribbed metal rods known as "rebar." Even in locations where basements are prevalent, slab foundations are typically laid to serve as the base for structures like garages, pole barns, and sheds. Slabs are the least expensive of the three main foundation types but provide no storage or utility space, as the home actually sits directly on a large platform of solid concrete. Slabs have the disadvantage of being difficult and expensive to repair when they settle and crack, and plumbing lines that protrude from the soil upward through the concrete can also be expensive to repair. In areas where the underlying soil is thick or prone to excessive expansion and contraction, cables are embedded which can be tightened to provide better horizontal support and minimize the width of cracks.

Crawl Space (Pier and Beam) Foundations

A pier and beam foundation consists of either vertical wood or concrete columns (piers) that support beams or floor joists above the ground. The areas between the soil and the bottom of the house floor is known as the crawl space. These foundations are built either at ground level or over a shallow excavation that varies in depth, but is commonly about 36 to 40 inches deep. The best crawl space foundations have a load-bearing concrete perimeter wall and concrete or steel piers, both having footings below the freeze line of the soil, along with a good barrier over the soil to keep moisture under control. Less expensive versions have no load-bearing perimeter walls, piers with shallow footings, and no moisture barrier at all over the soil. Crawl spaces that enclosed by a wall or by skirting must have vents on every side to allow air to circulate and help keep the soil dry under the home. These vents must be configured to prevent the entry of rodents and snakes. Crawl space foundations are most often used in areas where there is heavy clay content in the soil that can severely damage (crack) slab foundations, or in waterfront or flood prone building sites where the necessary floor height to prevent water penetration of the living space must be higher than a slab can normally provide. The primary advantages of crawl space foundations are that plumbing lines are readily accessible for repairs, and foundation settlement problems are easier and less expensive to correct than with slab foundations. A primary disadvantage occurs when these foundations are not properly maintained or are constructed without adequate ventilation, allowing water or pests to cause damage. Crawl space foundations without adequate insulation applied to the bottom of the house floor can be very energy inefficient in a cold climate.

Basement Foundations

A basement is a type of foundation which includes an accessible space between the soil and the bottom of the first floor of a home. This foundation provides living space below the home, below the ground elevation. It is basically a slab foundation with walls and a floor. Basements are most often built in cold weather climates such as the Northeast, Midwest and Rocky Mountains, and in places where the cost of excavation is not prohibitive. Basements start with a hole approximately 8 feet deep, however, some homeowners will opt for a 9 or 10 foot deep basement wall to increase height and volume of useable space. The floor and walls are built, then the house itself is built over that. Basement foundations have the advantage of providing useful space for utilities, mechanicals systems, and storage not available in the previous two types of foundations. The primary disadvantage of basements is that because they are mostly below ground level, they are vulnerable to leakage, mold formation, and flooding. Basements in wet climates must always have a working drain and pump in the floor to combat flooding.

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 Turkey Creek Knoxville  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 Moisture Control In Turkey Creek 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.

Basement Finishing Ideas For The Do-It-Yourselfer

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 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.

DIY Basement Foundation Repair

Many homeowners try to cut costs and increase their home's comfort level by installing a crawl space vapor barrier. This will instantly make your home healthier for you and your family, and prevent moisture damage, mold, mildew, foul smells and odors.

Most homeowners tend to look at their crawl space as separate space from their home, but in reality, the two are one. Water vapors that surface from the ground are continuously entering, creating undesirable conditions for you, your family, and your home.

Purpose

The purpose of a crawl space vapor barrier is to stop moisture and wetness from entering and affecting the floor and walls of your basement. Moisture tends to flow from warmer to colder spaces.

Many homeowners don't realize the importance of the proper installation, in order to keep moisture and water vapors from getting in the walls and floor of your basement-- condensation can lead to expensive structural damage. Also, if you can help control the moisture and dampness, you can greatly reduce the amount of energy required to cool and heat your home.

Preparation

When considering the installation of a vapor barrier, take into consideration two spaces in your home; the crawl space and the attic. Humidity tends to build in the walls of both these areas causing mold, mildew and dry rot. This can cause severe health issues for adults and children, especially for those with asthma, breathing difficulties, and allergies. In addition, it can cause severe structural damage to your home.

Some homeowners think that because they insulate the floor joists there is no need to do any additional work, but these items do not serve the same purpose!

Tips for Installation

One of the most popular do-it-yourself vapor barrier products is polyethylene, or plastic sheeting. This plastic sheeting comes in various thicknesses; 4mm, 6mm and 10mm.

With today's technology, this product is made from a high quality material, resistant to rips and punctures. Always check the soil so there aren't any objects or materials that may damage the lining. The slightest puncture, rip or tear could compromise the entire system.

Always, make sure the space is dry before you begin any repairs. To remove the moisture, you may need a dehumidifier.

Overlap the barrier a minimum of 12 inches on the side walls. Be sure it is tight. Use furring strips and masonry nails to firmly secure the lining then caulk along the joints.

Seal all the seams with a heavy duty tape. However, it is recommended not to use tapes that are not specially designed for sealing vapor barriers. When working in the basement you will be forced to contend with pipes, make the proper cuts and seal securely with tape.

The completion of your crawl space vapor barrier will be the best investment you can make in your home.

Crawl Space Insulation and Its Benefits

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 Three Basic Types of Home Foundations

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®.

What to Do About Basement Waterproofing Before It's Too Late

Many homeowners try to cut costs and increase their home's comfort level by installing a crawl space vapor barrier. This will instantly make your home healthier for you and your family, and prevent moisture damage, mold, mildew, foul smells and odors.

Most homeowners tend to look at their crawl space as separate space from their home, but in reality, the two are one. Water vapors that surface from the ground are continuously entering, creating undesirable conditions for you, your family, and your home.

Purpose

The purpose of a crawl space vapor barrier is to stop moisture and wetness from entering and affecting the floor and walls of your basement. Moisture tends to flow from warmer to colder spaces.

Many homeowners don't realize the importance of the proper installation, in order to keep moisture and water vapors from getting in the walls and floor of your basement-- condensation can lead to expensive structural damage. Also, if you can help control the moisture and dampness, you can greatly reduce the amount of energy required to cool and heat your home.

Preparation

When considering the installation of a vapor barrier, take into consideration two spaces in your home; the crawl space and the attic. Humidity tends to build in the walls of both these areas causing mold, mildew and dry rot. This can cause severe health issues for adults and children, especially for those with asthma, breathing difficulties, and allergies. In addition, it can cause severe structural damage to your home.

Some homeowners think that because they insulate the floor joists there is no need to do any additional work, but these items do not serve the same purpose!

Tips for Installation

One of the most popular do-it-yourself vapor barrier products is polyethylene, or plastic sheeting. This plastic sheeting comes in various thicknesses; 4mm, 6mm and 10mm.

With today's technology, this product is made from a high quality material, resistant to rips and punctures. Always check the soil so there aren't any objects or materials that may damage the lining. The slightest puncture, rip or tear could compromise the entire system.

Always, make sure the space is dry before you begin any repairs. To remove the moisture, you may need a dehumidifier.

Overlap the barrier a minimum of 12 inches on the side walls. Be sure it is tight. Use furring strips and masonry nails to firmly secure the lining then caulk along the joints.

Seal all the seams with a heavy duty tape. However, it is recommended not to use tapes that are not specially designed for sealing vapor barriers. When working in the basement you will be forced to contend with pipes, make the proper cuts and seal securely with tape.

The completion of your crawl space vapor barrier will be the best investment you can make in your home.

Basement Waterproofing Kingsley Station TN

The crawl space has an integral role towards a home’s overall value as well as the living space above. Most homeowners in Kingsley Station Knoxville  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 Encapsulation In Kingsley Station 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.

DIY Basement Foundation Repair

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.

Crawlspace Vapor Barrier Mythbusters

Before you sign that independent contractor agreement, consider this:

You're hungry, and you and your special someone decide to eat out. You drive down the road and find two restaurants standing next to other. From the outside, they seem about the same with one significant difference: the parking lot in front of one restaurant is nearly empty. The other restaurant? Packed! The lot is nearly full, and there's a crowd at the door. Through the restaurant windows you see smiling faces and filled tables. You pull in, and when you're greeted at the door, you're told there will be a 45 minute wait for your table. Will you leave the restaurant and go next door to the one that can serve you immediately? Isn't there a reason the other one is empty?

If you're looking for a basement waterproofing contractor to work on your home, you've got more than a bad taste in your mouth to worry about. Symptoms of a wet basement include headaches, moldy basement carpeting, wet drywall, ruined personal possessions, spreading mold, smelly basement syndrome, fatigue after hours of cleaning, and an exhausted bank account. Don't take chances on the empty business- if you reach a basement waterproofing company with a long line, there must be an awful lot of people who think they're worth the wait.

If you're not sure if the basement waterproofing contractor you've decided to work with is the best in the business, there are many ways to check out their reputation. Visit the local Better Business Bureau web site and check out their reputation- any complaints registered with them will be public for three years. Compare them with other local dealers, taking into account the size of the businesses and how many jobs has been completed for each.

It's also a good idea to check the contractor consumer web site such as Yelp! Or Angie's List. If the local contractor is registered, then reviews, company information, and ratings for quality and service will be clearly laid out as well as anecdotal accounts created by customers of this contractor will be available. There's a lot of ways online to have a customer's feelings be heard nowadays.

As a final way to check on your basement waterproofing contractor, contact them and ask for references. Many contractors will collect references from previous jobs and will be able to connect you with testimonials and contacts that will be able to give you a personal account of the quality of their service. However, whether you check with the Better Business Bureau, Angie's List, or you're checking up on references, you'll be gathering information directly from former customers about what these basement waterproofing contractors are all about.

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

If you get three general contractors together and the topic of discussion turns crawlspaces and moisture control, you will probably hear six opinions. Even the experts seem to have different and often conflicting opinions about what tack is the best to take.

There has been much research on crawlspace encapsulation during the past decade. The US Environmental Protection Agency, the US Department of Energy, the ZEBRAlliance at Oak Ridge National Laboratories, and a non-profit research organization called Advanced Energy have all done excellent and groundbreaking research in the area of crawlspace encapsulation. Their research findings were instrumental in the last revision of the International Building Code. They all agree in a few, very important areas.

When considering your home, think of it as a single system. Your HVAC system, insulation, windows, attic, living space, and crawl space all work together. All of these building components need to be optimized and balanced to achieve maximum comfort, performance and energy efficiency. Your crawlspace is an important part of this system.

Your house is like a giant chimney. By natural convection, air is drawn in through crawlspace vents and air leaks. Because warm air rises, the outside air is drawn through the living space (along with mold spores, odors, and moisture) and exhausted through the attic. In the summer, your crawlspace is naturally cooler than the ambient outside temperature. So when the warm, humid outside air reaches the cooler crawlspace surface areas, the moisture condenses on framing, plumbing, wiring, insulation and especially HVAC ductwork and "sweats", just like an iced tea glass sweats on your kitchen table in the summer. In the southeast it is not unheard of for crawlspace humidity to approach 100% and actually rain inside the crawlspace.

The moisture in your crawlspace creates an ideal environment for wood destroying organisms, mold, and mildew. It can saturate and destroy the effectiveness of your insulation and promote wood rot. And because of the chimney effect, the humid crawlspace air, full of mold and mildew spores, eventually finds its way into your living space creating an unhealthy environment and causing your air conditioning to work overtime to dehumidify the air. Just a vapor barrier might help a bit, but most of the moisture is coming from outside, not your dirt, crawlspace floor.

So, the alternative to a vented crawlspace is an encapsulated (sealed) crawlspace. Crawlspace encapsulation involves sealing all outside vents, installing a high-performance vapor retarder on all exposed wall and floor surfaces at or below grade, insulating the walls and rim joist, and conditioning the air.

The prevailing research claims that by insulating the walls and rim joist, it is unnecessary to insulate the floor. However, if the existing floor insulation is in good condition, leave it in place. We generally recommend a rigid foam board insulation that is fire-retardant, low VOC, and offers an R-13 value or greater. It cuts easily and can be used for sealing existing crawlspace vents too. The sill plate should be caulked and paper-faced fiberglass insulation is used to insulate the rim joist.

The building codes in most areas require the air in an encapsulated crawlspace to be conditioned. That generally means adding a dehumidifier or using the existing HVAC system to condition the air. The EPA and the Department of Energy recommend using the existing HVAC system at a rate of one cubic foot per minute of conditioned air per fifty square feet of crawlspace area. A qualified HVAC contractor can add one or two 4" or 6" vents to a system for a nominal cost. The vents are usually equipped with a butterfly valve that can be adjusted to get the desired air flow.

We prefer using this method since the installation of the vents is generally less expensive than a crawlspace dehumidifier. And since running a dehumidifier is about the same as running a small refrigerator, the cost of conditioning the air with an HVAC system is generally less than running a dehumidifier. Remember that you're not trying to heat and cool your crawlspace; you're just adding a small amount of conditioned air. A relative humidity target of 60% or lower is a good place to start.

When comparing high performance vapor barriers, look at puncture and tear resistance. Other than being absolutely water tight, a high performance vapor barrier should also be flexible, fire resistant, low VOC, and lightweight. There is a world of difference between the 6 mil vapor barrier material sold in most hardware stores and a high performance specialty product. Most reputable suppliers will provide samples.

In addition to dramatically increasing indoor air quality and protecting the structure of your home, several research studies from Advanced Energy indicate that crawlspace encapsulation can actually lower energy usage. These studies were done in several parts of the country with varying climates.

Crawl Space Repair Without a Fan or Vent

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.

Before you sign that independent contractor agreement, consider this:

You're hungry, and you and your special someone decide to eat out. You drive down the road and find two restaurants standing next to other. From the outside, they seem about the same with one significant difference: the parking lot in front of one restaurant is nearly empty. The other restaurant? Packed! The lot is nearly full, and there's a crowd at the door. Through the restaurant windows you see smiling faces and filled tables. You pull in, and when you're greeted at the door, you're told there will be a 45 minute wait for your table. Will you leave the restaurant and go next door to the one that can serve you immediately? Isn't there a reason the other one is empty?

If you're looking for a basement waterproofing contractor to work on your home, you've got more than a bad taste in your mouth to worry about. Symptoms of a wet basement include headaches, moldy basement carpeting, wet drywall, ruined personal possessions, spreading mold, smelly basement syndrome, fatigue after hours of cleaning, and an exhausted bank account. Don't take chances on the empty business- if you reach a basement waterproofing company with a long line, there must be an awful lot of people who think they're worth the wait.

If you're not sure if the basement waterproofing contractor you've decided to work with is the best in the business, there are many ways to check out their reputation. Visit the local Better Business Bureau web site and check out their reputation- any complaints registered with them will be public for three years. Compare them with other local dealers, taking into account the size of the businesses and how many jobs has been completed for each.

It's also a good idea to check the contractor consumer web site such as Yelp! Or Angie's List. If the local contractor is registered, then reviews, company information, and ratings for quality and service will be clearly laid out as well as anecdotal accounts created by customers of this contractor will be available. There's a lot of ways online to have a customer's feelings be heard nowadays.

As a final way to check on your basement waterproofing contractor, contact them and ask for references. Many contractors will collect references from previous jobs and will be able to connect you with testimonials and contacts that will be able to give you a personal account of the quality of their service. However, whether you check with the Better Business Bureau, Angie's List, or you're checking up on references, you'll be gathering information directly from former customers about what these basement waterproofing contractors are all about.

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 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.

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

Thinking Long-Term Safety & Health With Proper Foundation Structural Repair & Basement Waterproofing

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.

cost to encapsulate crawl space

Crawl Space Repair Without a Fan or Vent

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.

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

Owning a home with a basement can give us additional living space that is not typically available in a home with a crawl space. Many people put recreational rooms in the basement as well as using them for storage and often as a personal workshop. It may be difficult, however, whenever water in the basement becomes a problem. There are really two different ways in which water can invade this area of our home, both of which will take some form of waterproofing to correct. They can either come in slowly, almost undetected by us or it can quickly invade our basement and cause it to be flooded.

Since the basement is below ground level, moisture is often a problem, even if it is not visible. It may show up as mold or mildew that begins to appear on the walls and although you cannot actually see the moisture that is present, there are plenty of telltale signs that will help to identify the fact that you have a problem.

Doing a little bit of basement waterproofing for this usually means putting a specific type of paint on the walls or perhaps even spraying them down with chemicals so that they are impervious to mold growth. It may also help if you run a basement dehumidifier on a regular basis, even after you have completed the basement waterproofing project.

The other way that water can invade our basement is all at one time which can cause it to be flooded. I have personally had a difficulty with this for many years and it can be destructive, especially if you use the basement for living space or storage. If the water is coming in at one specific location, sealing that location in some way or another may help to cure the problem a little bit.

There may be times, however, whenever more drastic measures need to be taken. If you're basement floods on a regular basis, you may need to dig down to the bottom of your foundation on the outside of the walls and install a French drain. This will divert any water away from the house so that it does not end up in your basement.

Having a problem with water in your basement is simply keeping you from enjoying part of your house. Although waterproofing your basement is going to take a little bit of work, it will all be well worth the effort whenever you can take this part of your home back again.
