Crawl Space Moisture Control Pleasant Ridge TN

The crawl space has an integral role towards a home’s overall value as well as the living space above. Most homeowners in Pleasant Ridge 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 Waterproofing In Pleasant Ridge 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.

Crawl Space Repair Without a Fan or Vent

When a home has sagging floors, the signs many be obvious, or they may be quite subtle. Here are some questions a home owner can ask himself to glean whether or not sagging floors is a real problem for his home.

  • Does it seem that the home's floors sag towards the middle of the room?
  • Does furniture slide away from walls and creep towards the middle of the room?
  • Are there gaps in between the home's floor and baseboards?
  • Do the home's cabinets rattle when someone walks through a room?

Many homeowners ask what causes sagging floors. Sagging floors can be caused by several factors:

  • A shifting foundation beneath the home
  • Floor joists in the home that have been weakened by excessive moisture
  • Excessively large of spans between floor joists without enough support
  • Excessive or heavy loads (furniture, gym equipment, granite) in the room(s) above a home's crawl space
  • The use of temporary shims to fill flooring gaps; shims settle and shift out of place over time

The solution is more simple than it might seem! Adjustable steel crawl space supports are an economical and quick solution that can withstand the test of time. These adjustable posts are a permanent solution that work by transferring the weight of the home's flooring structure to more competent soils beneath the home. Many homeowners will attempt a do-it-yourself solution for sagging floors by inserting wooden shims to prop the floor back up. This is only a temporary band-aid and does not address the fundamental issues with the flooring structure. Shims made from wood, which are often a homeowner's first solution for the repair, can slip, shift and rot over time.

By contrast, the adjustable steel supports can be installed quickly (in less than one day), with little to no disturbance done to the property. Also, they are able to provide adequate support exactly where it is needed most. As the name implies, the supports can be adjusted in order to provide the exact amount of support needed, and they are fully compatible with a crawl space encapsulation system, should a home need that as well.

Crawl space repair is a common procedure done in many homes all over America. Unfortunately, many homeowners are unknowingly choosing temporary and insufficient means to support their homes, thinking that the professional and permanent solution will be too costly, disruptive, and time consuming. Adjustable steel crawl space supports can fix a home's sagging floors permanently without disrupting the family, the yard, or the wallet too much!

Crawl Space Supports

I've been in the crawl space business for 15 years and I've seen almost every system you could imagine - from spray foams to concrete to thin plastic sheets. Some are better than others, but the only real way to encapsulate the area beneath your home is to install a liner with zero permeability.

What is Zero Perm?

Zero Perm means just that absolutely no water, moisture, radon gas or odors will penetrate through it. Tests have to show 0.000 penetration of Hydrogen gas (the smallest gas molecule) through the membrane. The whole idea of spending the money to encapsulate the crawl space or basement is to STOP water, moisture, radon gas and any unpleasant odors. Liners that are 6, 12 and 20mil thick are NOT Zero Perm and will still let in harmful gasses as well as letting in moisture that will only continue to feed the mold and bugs that try to get in your home.

What Else Should I Look for in a Liner?

If you are going to spend the time & money to install a crawl space liner look for more benefits as well as zero permeability. Look for liners that are

- Energy Star Rated to get a 30% Tax Credit back on your purchase
- R Value of 5 to add insulation & increase your heating/ cooling efficiency
- Reflectivity value of 97% to prevent radiant heat loss
- Class A / Class 1 fire rating

Homeowners all over are finding that improving the homes they have is more cost effective than buying new. Some homeowners like the fact that they can save money by doing the work themselves and some still prefer to have someone else do the installation. Either way, using a Zero Perm, Energy Star Rated encapsulation system is a great way to pre-finish a basement or any area underneath your home.
