Crawl Space Repair Contractors in West Virginia


A region that has a lot of rain and humidity, like West Virginia, is more likely to have an excessive moisture problem in crawl spaces. Damp or wet crawl spaces invite mold contamination, insect attack, and structural rot. They may also contribute to bacterial hazards in the whole house, because whatever is in your crawl space air is in your house and affecting you, whether you spend any time in the crawl space or not.

It was once thought that adding vents to a crawl space was the right solution - that vents would allow moisture to pass in and out and eventually dissipate. But the truth is that the vents actually promote moisture because of the stack effect - a house's natural tendency to draw air in from the crawl space and lower levels upward into living spaces, sucks moist air in rather than letting moist air out!

To eliminate the humid crawl space from having any negative effects on the rest of the house, Basement Systems, the world leader in dry basement and crawl space technology, developed the CleanSpace System, an ultimate solution to vented dirt crawl spaces. The CleanSpace crawl space vapor barrier system completely isolates your home from the earth, dramatically reducing the humidity level in the air and in some cases, eliminating mold growth, rot, and critters from your crawl space to make the entire house healthier. And once you encapsulate your crawl space with our patented vapor barrier system, you will even gain valuable storage space in your home.

The Basement Systems International Network of Authorized CleanSpace dealers is a respected and highly professional network, and whether you live Charleston, Huntington, Parkersburg, Wheeling or Morgantown, we've got you covered. Click here to contact us or call 800-638-7048 to schedule a free quote for your crawl space moisture problem.

Crawl spaces have a bad reputation —as cramped, damp, dirty spaces that harbor bad-smelling mold, insects and other pests. The CleanSpace system of crawl space repair is designed to turn this ugly area into an asset —a part of your house you can actually be proud of. Our trained technicians make this transformation possible by combining waterproofing techniques with high-performance insulation, durable moisture barriers and effective air-sealing strategies.

    Curtis and his crew were great! They worked very hard for 3 days to finish the project and worked well together. While working on my project they discovered a leak in my furnace which I might not have found for a long time dripping in the soil but with the clean space the water showed up right away.

Project Location: Woodbridge Drive, Princeton, WV 24740

Comment: This is from the inspection report. I need it done to sell the house. Several buyers have backed away and I'm really in need of selling, " girders are not shimmed full width of piers. Areas of joists and band board are starting to rot due to long term elevated moisture levels in crawlspace. Wood decay fungi growth in areas in crawlspace." Then "Insulation was installed upside down and is wet due to high condensation levels. Wet subfloor above water main pressurevreducer-unknown cause. Probable mold growth and wood decay fungi in areas."

Project Location: Ridgeview Dr, Mount Lookout, WV 26678

Comment: We had some flooding under our crawl space due to faulty rain gutters, we fixed the gutters but now there is a horrible odor that comes up through the vents into the home.

Project Location: Groves Ford Road, Summersville, WV 26651

Comment: I get water in my crawl space. I need to find a way to stop it or remove it and keep it dry. There's basically an 8" trench on the inside of the block that holds the water after it seeps through the block. This trench is from where they dug the footers. The water sits on the footers.

Project Location: Kanawha Street, Moundsville, WV 26041

Comment: Need estimate on crawl space encapsulation, health issues envolved

Project Location: Painted Pony Lane, Valley Grove, WV 26060

Comment: 2190 sq foot crawlspace in L shape. 5 courses of 8" block tall on concrete footer. Modular home was built October-November 2016. Block was painted with black sealer on outside, and a footer drain was installed on the outside of the foundation. Crawlspace was filled with thin layer of 3/4" #57 limestone gravel. Crawlspace has vents on all sides allowing outside air to flow through. Crawlspace remains constantly damp, although there is no standing water. The block works appears wet, although it may be sweat. The gravel floor also appears damp in color. Over the past year I placed a remote temp/humidity sensor and during the summer the humidity stays at almost 99% at around 55 degrees F. During the winter it dips down to maybe 60% on the extremely cold days. I am concerned about future mold growth in the crawlspace. I am interested in solutions to significantly reduce the humidity, perhaps full encapsulation of the crawlspace.

Project Location: S Kerens Ave, Elkins, WV 26241
