Home > Crawl Space Encapsulation

Many homes built on crawl space foundations in the Southeastern United States suffer from poor moisture management. A home with a dirt crawlspace costs more to heat and cool. If your crawlspace is vented, those vents make your floors cold upstairs, if your ductwork is in the crawlspace there is also an energy drain as cold ducts strain to keep your home warm. In the summer, warm air that enters your crawlspace creates high humidity. Warm humid air that enters the crawlspace will place itself on the cooler components such as the sub-floor insulation and the wood sub-floor creating condensation and dampness.
If you get rid of the humidity in your crawlspace you can save 15% to 25% per year. For decades, building codes and conventional wisdom have prescribed ventilation with outside air as the primary method of moisture control in crawl spaces. In the humid Southeast, however, ventilation with outside air only makes moisture problems worse. Recent research by Advanced Energy, a Raleigh, NC based non-profit company and others indicates that a new type of crawl space system, with NO vents to the outside, can provide greatly improved moisture control and significant energy savings when properly installed.

Crawl space encapsulation means eliminating wet, damp, dirty crawlspaces and the health risks posed by mold, bacteria and fungus. It is designed to improve the value of your home while ensuring the health of your family. We at Basement & Radon Solutions have committed to installing superior crawl space encapsulation and radon mitigation systems in Western North Carolina for over a decade.
If you own your home we will do a free onsite inspection of your crawlspace with pictures that will identify problems associated with your crawlspace. Foundation cracks, basement waterproofing, sump pumps, dehumidification and French drain repairs are all in our line of services.
Next we will provide you with professional options to correct these issues and guarantee you a clean healthy crawl space system. Contact us today for a free evaluation of your crawlspace.
At Basement & Radon Solutions, we help our customers in Hendersonville and Asheville areas by getting to the root of the problem.

When a crawl space is sealed, radon gas can sometimes become trapped, just as it does in basements. To protect your family, every encapsulation we install in Western NC comes radon-ready.
The vapor barriers we use help reduce soil gases, but sometimes that isn’t enough. Without a radon-ready setup, you risk having to cut into your new liner later to add mitigation — weakening your investment.
Our team is licensed and certified by the National Environmental Health Association (NEHA). We always perform a radon test after encapsulation. If levels are elevated, we already have a professional plan in place to fix the problem efficiently.If a radon ready system is not installed prior to encapsulation and you find out that you have a radon problem, what happens next? Your new moisture barrier will have to be cut, the radon system installed and your liner repaired. This constitutes more repaired seams compromising the life and integrity of your investment and now you are dealing with another contractor in your home and on top of your new liner. Basement and Radon Solutions performs a radon test in every home after we seal or encapsulate a crawl space. If the home has radon, now there is a professional plan in place to simply correct the problem.
