Mold has emerged as a major issue for the building industry as of late 1900s. Homeowners and tenants have filed thousands of lawsuits and insurance claims regarding mold related problems that were not addressed by landlords, builders, and even pest management companies. Many of these lawsuits and insurance claims resulted in multi-million dollar settlements as there was a failure to either report mold in below-grade spaces or install the necessary waterproofing products in new, rented, or leased homes to protect individuals from the hazardous effects of mold.
During periods of rain and high humidity, crawl space wall vents become damp and contribute to moisture levels that exceed 70%. When moisture levels are this high, mold growth is a guarantee. Mold can grow virtually anywhere in the crawl space, but the more popular areas for mold growth are on the support beams, joists, and sills.
There has been groundbreaking research conducted in North Carolina that evaluates the sources, effects, and solutions for mold growth in below-grade spaces like the crawl space. Click on the image below to get the in-depth details of the research.
