    Crawlspace Encapsulation in Larchmont, NY

    This old crawlspace was letting water into this Larchmont, NY home. Using our CleanSpace liner, which acts as a vapor barrier, we were able to waterproof this home.

    Before

    After

    CleanSpace Encapsulation in Stamford, CT

    This crawlspace was damp and dirty before we encapsulated it with the CleanSpace vapor barrier. The vapor barrier is an effective solution to keeping the crawl space dry because it prevents moisture from passing through the floors and concrete walls of traditional crawl space structures, and has the added benefit of flexibility to cover irregular crawlspaces.
