Columbia receives approximately 50 inches of rainfall per year and sustains average annual relative humidity above 75%. The October 2015 "1,000-year rain" dropped more than 24 inches over the Midlands, leaving thousands of Columbia homes with widespread mold contamination when structural drying was inadequate — a direct demonstration of the damage this climate can cause.
Crawl space moisture is the primary mold pathway in Columbia. Older neighborhoods like Shandon, Earlewood, and Forest Acres have crawl space foundations where humid outdoor air drives relative humidity above 70% year-round, feeding active mold into floor joists and subfloor sheathing well before interior symptoms become visible.
South Carolina has no dedicated mold remediation license, but structural work requires a licensed general contractor. Verify technicians hold current IICRC AMRT certification, that the firm carries pollution liability insurance, and that post-remediation clearance testing is performed by an independent third party.
