Altra Dry is the market leader in crawl space encapsulation and crawl space repair. If you have crawl space mold, it is usually due to a moisture problem. All your problems with a wet crawl space can be solved by having it encapsulated. Before you can have a crawl space vapor barrier, you must waterproof your crawl space. This involves installing a crawl area sump pump and a French drain. Once this is done, then we move to the next phase and install a crawl space moisture barrier and crawl space dehumidifier. We offer basement waterproofing, water and fire damage restoration, mold remediation, and mold removal.
