The crawl space has an integral role towards a home’s overall value as well as the living space above. Most homeowners in Downtown 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 Downtown 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.
5 Helpful Tips For When it is Time to Encapsulate Your Crawl Space
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.
Improving a Home's Indoor Air Quality by Crawl Space Encapsulation
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.
