CleanSpace® vapor barrier is the perfect way to not only encapsulate your crawlspace, but also to make it functional. Other home improvement contractors, such as plumbers, that need to complete work under your home have told us how much easier their job is when a home has the CleanSpace® system. CleanSpace® seals the crawlspace from water and moisture and also insulates the area, keeping it at a comfortable temperature. You can even turn your crawlspace into a storage area and be assured your stored belongings are safe from water, bugs and dust.
