The crawl space has an integral role towards a home’s overall value as well as the living space above. Most homeowners in Cookeville 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.
The Best waterproofing crawl space In Cookeville 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.
Crawlspace Vapor Barrier Installation
I recently came across a Consumer Reports article that served as a good reminder to homeowners about some of the home's maintenance issues that are just too important to put off. With today's economy, it is easier to justify holding off on repairing a leaking basement wall crack because it seemingly does not pose an immediate threat, outside of a little inconvenience, of course.
Problems related to the foundation's structural stability or the indoor air quality of the home requires more immediate action; such issues are essentially putting the health and overall safety of the family at risk: not tomorrow, or a year from now, but at this moment.
While bad news for the homeowner, such problems are good for basement waterproofing and foundation repair contractors - the need for their services will always exist. The Consumer Reports article lists a couple of problem issues that the homeowner should be concerned about - the growth of mold and mildew and the formation of cracks in poured foundations. As a business owner who works with the basement waterproofing industry, these are two areas of concern that I am well familiar with.
The growth of mold and mildew can occur inside a home for endless reasons. The most prominent areas are basements and crawl spaces, where excess moisture is a sure bet unless the necessary measures are taken. Concrete walls are prone to the seepage of water vapor - leaking water from cracks in the foundation or the floor adds to the problem. The basement and crawl space provides the ideal environment for trapped moisture to eventually grow into mold spores and mildew.
Concrete cracks in poured foundation walls usually occur as a result of shrinkage or settling around the foundation. Cracks forming as a result of shrinkage in the concrete typically do not pose a structural threat, yet they may cause headaches for the homeowner the second they begin to leak water.
Whether such foundation cracks are structural or not, it is best not to leave them exposed for long, as it relates to the concern of the home's indoor air quality. These cracks, as well as in concrete floors, may provide an opening for soil gases. The infiltration of soil gases, in addition to the growth of mold and mildew can be enough to create an indoor air quality nightmare. The bad air circulating inside the basement and crawl space affects the entire home - 50% of the air circulating throughout the home originates from the home's lowest level.
Concrete cracking is unavoidable. Properly addressing them early on will minimize further problems down the road. Further indoor air quality concerns may also be addressed by implementing the proper waterproofing and sealing techniques throughout the basement and crawl space. There are plenty of qualified contractors throughout the United States and Canada available to service such jobs.
It's reassuring to know that our message is backed up by an objective source such as the Consumer Reports. You view the article at the provided link, http://shopping.yahoo.com/articles/yshoppingarticles/418/5-home-repairs-not-to-ignore/.
You can't put a price on the long-term stability of the home and health of the family.
Improving a Home's Indoor Air Quality by Crawl Space Encapsulation
Crawl spaces are inherently dirty smelly places that can contain all types of unwanted odors from mold & mildew to urine & feces. Some areas of the country can even have soil underneath the home with odorless, harmful gases like radon gas. I'm a big believer that the best long-term solution to solve these problems is to encapsulate the air underneath the home with a liner system. It is a inherently impossible to keep rodents, bugs and mold out of the area underneath the home since the soil is exposed - but it is relatively simple to create a barrier between the home and crawl space the keep out all these unwanted nuisances.
I had a very nice lady write me the other day telling me about this house she had just purchased that formerly had many cats living in the crawl space and they left behind the smell of a giant litter box underneath her home. The odors were coming up through the wooden floor and creating a very fowl smell in the house. She told me she tried all different solutions: spreading baking soda, spraying an enzyme treatment originally intended for carpets & laying down new top soil - needless to say none worked. I wrote her back, apologized for her wasted time and suggested that she treat her crawl space like a wild beast that you can't defeat, only contain. She took my advise, installed a crawl space encapsulation system and the smells immediately went away.
Encapsulation systems are rated by permeability - 0.000 is the best, normal plastic is 0.01 and wood is 0.2. To stop all smells, moisture and gases look for an encapsulation liner system with a 0.000 permeability rating. A zero perm liner will also completely weatherize the crawl space and save on energy bills since the outside air won't be able to leak into the home.
Thin Liners Don't Encapsulate the Crawl Space
I can't tell you how many times I've received a call or been sent an email from a homeowner telling me how they went to Home Depot, bought a liner system as thin as a trash bag, spent an entire weekend installing it then didn't solve their problem. Cheap store bought liners are typically 6-12 mil, 0.01 permeability and even new they don't stop gases like Radon - they are also easily chewed through by bugs and rodents leaving the crawl space a year later leaking air like a sieve.
What to Look for
40 - 60 mil thickness, 0.000 permeability and antimicrobial so mildew can't grow on the liner. Encapsulation systems don't need a contractor to install (although trust me they won't tell you that). Look for the Energy Star Rated logo.
