Savannah receives approximately 49 inches of annual rainfall, with peak moisture June through September. Summer relative humidity regularly exceeds 75 percent, and sea-level elevation near the Savannah River keeps groundwater close to the surface. Hurricane Matthew in 2016 and Hurricane Dorian in 2019 both made direct impacts, leaving saturated structures that developed mold before drying could begin.
Crawl spaces south of the Historic District lack adequate ventilation, allowing soil moisture to condense on floor joists. Masonry moisture infiltration in historic row homes built before modern vapor barriers creates mold without any discrete water event. Roof and flashing failures on aging historic properties are a common documented cause.
Georgia has no state mold remediation license. Look for IICRC Applied Microbial Remediation Technician (AMRT) certification, general liability and pollution liability insurance, and familiarity with Metropolitan Planning Commission requirements. Call for 24/7 assessment now.
