The crawl space has an integral role towards a home’s overall value as well as the living space above. Most homeowners in Madison Nashville don’t think twice about their crawl space unless they have to make repairs to plumbing, heating ducts or house wiring. While often thought of as no more than a storage area, it also has a tremendous impact on the overall indoor air quality of the entire home.
The Best Crawl Space Remediation In Madison 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.
A Closed, Sealed Crawlspace - What a Really Bad Idea
Crawl spaces are known for their aesthetic presence-- NOT! When you talk about a crawl space you probably touch upon the dirt floor, the mold buildup, the puddles, the stench, oh and you can't forget about the insulation falling from the ceiling or the dusty old vents.
Unfortunately, this environment can cause a whole lot more damage to the rest of your home than you may think.
Crawl spaces and basements have huge problems with moisture. The stack effect is the proper name for the well-known process of warm air rising, which absolutely has a lot to do with moisture.
When the hot and humid air from the outside enters into the crawl space, the air begins to cool and the warm air pushes and exits through the upper levels. When the hot air cools by even one degree, the relative humidity rises by 2.2 percent.
This is why you find condensation and water buildup on other surfaces! Once this moisture begins to build and the humidity rises in the space mold begins to grow. Mold will continue growing and prospering if it has moisture, organic material to eat and a comfortable temperature. You cannot remove mold by wiping it away, but you remove mold by eliminating the source of moisture.
In other words-- close the vents, seal the space and install a sump pump!
As we just learned, air tends to rise within a home. So, when old-school thought encouraged people to install vents, it was unfortunately saying that air would come in through one vent and go out the other vent. This is not the case. Instead, the air comes in through both vents increasing moisture and humidity. In addition, as the crawl spaces conditions worsen due to the vents, the air quality in your home also lessens.
It's been estimated that a third to one half of the air on the first level actually comes from the crawl space, so whatever is growing and prospering beneath your home you can be sure to be breathing in throughout the rest of your home.
In addition, some spaces have fans as well. A fan will only blow the mess around and worsen the problem. Both of these "solutions" also heighten your energy bills and shorten the life of some of your homes heating and cooling appliances. Your air conditioning will be working a whole lot harder to cool and your heating system will be working very hard to keep your home warm. Unfortunately, the vents and fans in your crawl space are a big factor in your energy waste and increase in expenses.
Since crawl spaces have problems with moisture control and mold growth the best solution will close-off air flow from the outside and prevent moisture from entering through the soil, cracks and vents. In addition, the solution must prevent mold growth and include a water drainage system for when leaks occur and water somehow makes its way into the space.
This solution is to install the CleanSpace Crawl Space Encapsulation System, which will enclose the entire crawl space with a vapor barrier that also separates the space from the soil foundation. In addition, you can close-off the vents and include a sump pump drainage system.
No more vents, no more fans equals better air quality and a cleaner environment.
Crawlspace Vapor Barrier Mythbusters
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.
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.
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.
