Mold Inspection & Remediation in Austin, TX

Austin averages about 36 inches of precipitation a year under NOAA's 1991–2020 normals, with May the wettest month at about 5 inches, followed by October and June. The city sits along the Balcones Escarpment, where moist Gulf air meets the hills and storms can drop heavy rain in a short time, and creeks rise quickly.

The Halloween flood of 2013 showed what that means for homes. Onion Creek rose to historic levels overnight, and more than 600 homes were heavily damaged; the city estimated at least 1,100 homes were affected across Austin, roughly 500 of them in Dove Springs. Onion Creek flooded again in the fall of 2015, and the city has since bought out hundreds of homes in its floodplain.

Austin's older central neighborhoods, such as Hyde Park, Travis Heights, and Bouldin Creek, include many houses on pier-and-beam foundations, where crawl spaces collect moisture from leaks and poor drainage. Newer homes to the north and southwest usually sit on slabs, with air handlers in the attic and plumbing under the foundation. Hard freezes like the February 2021 winter storm burst pipes across the city. The EPA recommends drying wet materials within 24 to 48 hours to keep mold from taking hold.

The Austin figures above draw on local contractor price guides: inspection ranges from guides published in 2026, the typical job range from a 2026 Austin guide, and the per-square-foot range from a 2025 Austin cost guide. On a large job expect three line items rather than one: the assessor's inspection and protocol, the contractor's removal, and the clearance assessment at the end. Crawl space access, drywall removal after creek water, and rebuilding are often priced separately, so ask each company what its number includes. Our mold remediation cost guide breaks down the variables.

Before anyone cuts into a wall in your Austin house, ask for two TDLR license numbers, one from the assessor and one from the remediation contractor, and look both up at tdlr.texas.gov. Texas requires that split: the company that maps the mold and writes the protocol may not be the company that tears it out on the same job, so the person sizing the problem has no stake in billing for it.

The 25-square-foot line matters more than most owners expect. A crawl space under a Travis Heights bungalow or a closet wall behind a failed water heater passes 25 contiguous square feet quickly, and at that size removal has to be handled by a licensed remediation contractor. Since September 1, 2025, the crew members on site also need their own TDLR license or registration, not just the company. You should get the Consumer Mold Information Sheet before work begins and a Certificate of Mold Damage Remediation within 10 days after the job passes clearance. An owner of a home with fewer than 10 units may do the work personally without a license.

Which policy pays depends on where the water came from. Creek water that rose into a Dove Springs or Onion Creek living room is flood damage, and only a flood policy covers it; a standard homeowners policy does not. FEMA notes that a new National Flood Insurance Program policy usually has a 30-day waiting period, so buying one when the forecast turns stormy is too late for that storm.

A pipe that split in the attic during a freeze like February 2021 is a different story. The Texas Department of Insurance says most homeowners policies cover sudden and accidental water damage and mold on items damaged that way. A drip under a sink that ran for months usually is not covered, and many policies limit or exclude mold cleanup. Take photos before anything is torn out and call the claim in quickly. Once the job is finished, file away the Certificate of Mold Damage Remediation: if it shows the cause was fixed, an insurer may not base an underwriting decision on the earlier mold damage or claim.
