The crawl space has an integral role towards a home’s overall value as well as the living space above. Most homeowners in Knoxville 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 crawl space remediation In Knoxville 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.
How To Protect Your Health And Get Rid Of Awful Smells With Crawl Space Encapsulation
There are advantages and disadvantages in having a crawl space under your home. Advantages, perhaps, a slightly elevated home may be more attractive than a home on a slab. Plus, you can make repairs and modifications to plumbing, heating, and electrical services.
Disadvantages, a crawl space is an area that is never cleaned. Under the vapor barrier the humidity is always 100% so mold and bacteria are always present. Termiticides, other chemicals, even rodent droppings may be present, and odors and gases that emanate will migrate into the home's living space unless proper ventilation is installed. Whether on a slab or elevated, if radon is present, good ventilation is required.
There are several technologies on the market in regard to moisture control. One is encapsulation, sealing the crawlspace. Though this might lower humidity, it's costly and there is no dilution or replacement of stagnant, poor quality air. Again, if radon is present, ventilation is required.
Another technology is to install a dehumidifier in the crawl space. This can lower humidity, but again will not dilute or replace the stagnant air. Another point to think about is that the dehumidifier will be costly to operate. More importantly, using a dehumidifier requires you to close tightly the crawl space. Thus, the home's living space air quality is going to be lowered because the crawl space air is not diluted and replaced with fresh outdoor air.
Some systems use a dehumidifier control (dehumidistat) to operate a crawl space vent fan. This sounds like it's going in the right direction. However, the technology isn't quite right. Here's why. Suppose the outdoor air is getting worse (wetter). Though the dehumidistat control is in the crawl space, it will quickly recognize this wetter air condition and begin ventilation, even though ventilating is going to make crawl space wetter. Another problem with a dehumidistat control is that most of them are not made for the difficult environment of a crawl space, so their warranties are short, 30 days to 1 year maximum for the dehumidistat.
There is another system that uses special technology different from all the others mentioned above. This special technology makes a comparison of the actual moisture content of both the air inside the crawlspace and the outdoor air. The result is that it pauses and does not ventilate when bringing in outdoor air is going to make the space wetter. Then, as the outdoor air is getting drier and is able to improve the moisture and air quality in the crawlspace, then this ventilator moves a lot of air which dilutes and replaces stagnant air, ultimately improving your home's living space air quality.
This system, called the Smartvent, is made in the USA, is used from Florida to Alaska... San Diego to Nova Scotia.
This system is a proven system, and it is the only system to have undergone a year long test where crawl space humidity averaged 46%. Besides the unique technology this system employs, it also has the longest warranty of all ventilators, five years.
Basement Finishing Ideas For The Do-It-Yourselfer
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.

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.
