Crawlspace Solutions

Standing water in your crawlspace is fuel for the growth of mold and mildew. Mold and mildew spores can get inside the house if left unchecked and might cause problems for individuals with asthma or any other breathing difficulties. The constant moisture will also soak into the insulation causing it to eventually fail. Constant water vapor can cause your floor joists and framing to rot resulting in the need for a costly repair.

Crawlspace Interior Drain System


The Crawlspace Interior Drain system (CID)  is installed inside the crawl space covering the entire perimeter. When water travels underneath the footing or through the wall our system collects all of the water and carries it to the sump pump. The sump pump then discharges the water away from the foundation, keeping your crawl space dry. After installing the drain we apply our vapor barrier on the floor. Our vapor barrier ranges from 9-36 millimeters. This system comes with a free transferable lifetime warranty guaranteeing your crawl space dry.

Crawlspace Power Post

 Our foundation specialists install an adjustable power post that stabilizes the floor system. Our power posts are supported with a permanent footer and attached to a beam that spans the area of the sagging floor. This also helps prevent the floor from bouncing and creaking.

Crawl Space Dehumidifier

 Does your crawlspace or basement have a musky smell? This is because of your home’s humidity level. We can help you get rid of these problems by installing a commercial grade dehumidifier.



Encapsulating not only seals your crawlspace but it can also help to eliminate musty odors and humidity levels.  If you think that your crawl space only serves as storage space for infrequently used items, you might be surprised. Your crawl space just might be the number one spot where moisture enters your home. Moisture control doesn’t sound like that big of a deal but the problem is what that moisture brings with it, mold. Mold growth can begin within 24-48 hours and not only can mold damage your foundation and decrease the value of your home, but it can also be detrimental to the health of you and your family.

It is imperative that you properly seal out moisture from your crawl space and Tri-State has the means to help; WARNING: Don’t try this at home. It is important that you have a professional inspect and treat your home for moisture and mold. Improper elimination of mold may result in mold contamination throughout your home further endangering your foundation structure and your health.
