Frisco receives roughly 40 inches of annual rainfall, but dry stretches of 30 to 60 days are regularly broken by storms dropping two to five inches in hours. Expansive Collin County clay soils create hydrostatic pressure against slabs, and tightly sealed new construction traps moisture from HVAC problems and construction defects. Mold can establish within 24 hours of any moisture event.
Common mold triggers include foundation slab leaks saturating flooring before appearing above ground and HVAC units that short-cycle and fail to dehumidify. Winter Storm Uri in February 2021 caused burst pipes in hundreds of Frisco homes, many developing mold during remediation delays.
Texas Occupations Code Chapter 1958 requires a Texas Mold Remediation Contractor (TMRC) license; the same entity cannot perform both assessment and remediation. Ask for the contractor TMRC license number and verify it at the Texas DSHS portal before any work begins. Call 24/7 for certified assessment immediately.
