Mold growth typically enters crawl spaces through moisture events, lack of maintenance, or improper construction.

Within crawl spaces, a proper mold remediation must include steps to correct the moisture issues, not just a clean-up of mold.
Crawl spaces of homes have particular problems with relative humidity, as they are surrounded on five (5) surfaces by the ground. The contact with the ground keeps this area cool and moist. If areas like a crawl space are not conditioned and controlled, high relative humidity conditions can prevail and affect your structureĆs building components like joists, floor sheathing, walls and flooring.
The process for mold removal in crawl spaces includes negative air machines, HEPA vacuuming, antimicrobial treatments, and antimicrobial sealant. In addition, the source of moisture must be corrected to prevent recurrence of the mold growth. Often, a combination of a dehumidication system and a vapor barrier, along with maintenance, will suffice to prevent further mold growth.
