Houston averages approximately 50 inches of rainfall per year, placing it among the wettest large U.S. cities. Dew points regularly exceed 70°F from June through September. Hurricane Harvey in 2017 flooded thousands of homes across Energy Corridor, Meyerland, and Spring Branch neighborhoods, generating mold that required remediation months after the initial cleanup.
Houston's clay-heavy soil expands and contracts seasonally, stressing slab foundations and allowing ground moisture to wick upward into slab-on-grade homes. Stachybotrys and Cladosporium are both common following flood intrusion, and active colonies can expand measurably within 24 to 48 hours under summer humidity conditions.
Texas Mold Assessment and Remediation Rules (TAMRR, 25 TAC Chapter 295) require Texas Department of State Health Services licensing for assessors working above defined square-footage thresholds. Confirm your inspector's TDSHS credentials before work begins. Request a written remediation protocol and post-clearance testing. Call for 24/7 emergency assessment now.
