Augusta's average humidity exceeds 70 percent year-round and summer temperatures regularly reach the 90s — conditions that allow mold to colonize wet materials within 24 to 48 hours. The city receives roughly 47 inches of rain annually, and Tropical Storm Irma in 2017 left dozens of CSRA properties with hidden moisture intrusion that produced active mold colonies.
Augusta's tight red-clay soils drain poorly around foundations, accelerating crawl space deterioration. Older homes in Summerville and Olde Town frequently present with Stachybotrys in crawl spaces after even modest plumbing leaks, and continuously running AC systems create condensate that becomes a secondary moisture source inside walls.
Georgia has no specific mold remediation license, but structural work requires a Georgia State Licensing Board contractor's license. Ask for proof of insurance, an IICRC S520-compliant scope of work, and a third-party post-remediation clearance report before work begins.
