Lubbock receives only about 18 inches of annual rainfall, but monsoon afternoons from July through September push relative humidity to 70–90%. Evaporative coolers — common in West Texas homes — introduce outdoor humid air into structures, and a malfunctioning cooler pad is a frequent mold source. Lubbock averages six or more significant hail days per year, and roof failures go undetected for months while attic mold establishes.
Flash flooding along Yellowhouse Canyon draws caused widespread crawl space flooding in September 2015. Shallow Ogallala Aquifer groundwater seeps into foundations near Canyon Lakes and Tech Terrace. Trapped moisture enables rapid colony growth after any intrusion event.
Texas Occupations Code Chapter 1958 requires a TDSHS-licensed Mold Remediation Contractor for projects over 25 contiguous square feet and a separately licensed Mold Assessment Consultant to write the protocol. Confirm both licenses on the TDSHS lookup and ask to be named additional insured. Call 24/7.
