Why Houston Homes Need Mold Inspections
Extreme humidity year-round, frequent flooding (Hurricane Harvey 2017 affected 300K+ structures), poor drainage in clay soil, AC condensation issues
Did you know? Houston’s combination of Gulf Coast humidity and flat terrain makes it one of America’s top mold hotspots. After Hurricane Harvey in 2017, an estimated 40% of affected homes developed mold within 48 hours. For more guidance, EPA provides expert resources on mold testing guidelines.
