The crawl space has an integral role towards a home’s overall value as well as the living space above. Most homeowners in Collierville 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.
10 Reasons to Encapsulate Your Crawl Space
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.
Crawl Space Supports
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.
