Houston is among the most mold-prone U.S. metros: nearly 50 inches of annual rain, average relative humidity above 70%, and Hurricane Harvey alone flooded over 200,000 homes. The region's clay-heavy soils create chronic sub-slab moisture wicking into slab-on-grade foundations. In Houston's warm, humid conditions mold establishes within 24 to 48 hours of any water intrusion.
HVAC failures dominate Houston mold calls — oversized units that short-cycle leave indoor humidity high, while undersized units freeze coils and overflow condensate pans. Harris, Fort Bend, and Montgomery counties carry some of the highest repetitive flood loss rates in the country, particularly along Brays and Greens Bayous.
