This crawl space encapsulation included a Sedona dehumidifier in order to eliminate damp, musty odors in the crawl space by drying and filtering the air. The CleanSpace 20 mil. thick liner, very similar to a pool liner, was also installed. The bright white appearance of the liner makes for a much more accessible and clean environment underneath the home to allow customers to easily ensure that the crawl space is free of debris, mold, insects, etc.
