A unencapsulated crawl space can cause a whole host of problems if left unattended.If left unsealed the crawl space can invite mold, mildew, and indoor allergen problems, as well as leave the home above uncomfortable, or with spongy floors that will need to be replaced due to moisture damage. Using our Clean Space Vapor Barrier, a thick, moisture resistant barrier, we've sealed this crawl space off from the potential dangers of an unfinished crawl space.
