Crawl space moisture barrier installation

In as little as one day, your home could be protected from humidity, mold, pests, flooding, and odors! The CleanSpace® Crawl Space Vapor Barrier can be installed in less than a day. During the installation process, your crawl space contractor will first inspect your crawl space for any water or structural damage before the moisture barrier is installed. Then, your contractor will seal any crawl space vents to prevent humid air from entering and becoming trapped under the liner. Finally, your contractor will line the foundation walls and floor with the CleanSpace® poly to create a continuous air and moisture barrier.

Before and After Installing Moisture Barrier


Moisture that enters the crawl space through vents and soil can ruin insulation and also encourage mold growth and wood rot.


Covering the crawl space floor and walls with a heavy-duty moisture barrier eliminates moisture problems, makes the living space more comfortable and cuts heating & cooling costs.
