Mold Remediation in Austin, TX

Texas treats mold removal as a two-company job. A licensed mold assessment consultant writes the protocol, a licensed remediation contractor follows it, and the consultant comes back at the end to confirm the work passed. That structure is set by the Texas Mold Assessors and Remediators rules administered by the Texas Department of Licensing and Regulation (TDLR), and it applies once the mold covers 25 contiguous square feet or more.

Three Austin jobs and how each one goes

Creek and flash-flood water. The Halloween flood of 2013 pushed Onion Creek into hundreds of homes in a single night, and the area flooded again in 2015. When creek water gets inside, crews treat it as contaminated: carpet and pad go, drywall is cut out well above the water line, and wet insulation is bagged. The EPA's guidance is to dry building materials within 24 to 48 hours; past that window, expect remediation rather than a simple dry-out.

Crawl spaces under older homes. Many houses in Hyde Park, Travis Heights, and Bouldin Creek sit on pier-and-beam foundations. Leaking drain lines, poor yard drainage, and humid summer air settle in the crawl space, and growth spreads across joists and the underside of the subfloor before anything shows in the living room. Crews remove soaked insulation, clean or replace affected wood, and the moisture source gets fixed, often with drainage work and a ground vapor barrier. Our guides on crawl space mold and mold on a subfloor show what is usually saved and what is replaced.

Slab homes with attic equipment. In newer neighborhoods to the north and southwest, the air handler and ducts usually live in the attic. A clogged condensate line or a split pipe can soak ceiling drywall and insulation from above. The February 2021 winter storm burst pipes across the city, and many of those attics and ceilings needed remediation weeks later.

The Texas paperwork that protects you

Before work begins on a licensed job, you should receive the Consumer Mold Information Sheet. When the post-remediation assessment passes, the contractor must give you a Certificate of Mold Damage Remediation within 10 days. Keep it. Texas sellers have to hand buyers copies of certificates issued in the previous five years, and when a certificate shows the cause was fixed, an insurer may not base an underwriting decision on the earlier mold claim. A job done without that paper is harder to explain at resale.

What mold remediation costs in Austin

Local price guides put most Austin residential jobs at about $1,433 to $6,000, with quotes commonly written at $10 to $25 per square foot. Structural growth or whole-house work can pass $10,000. On a licensed job you will usually see three separate bills: the consultant's assessment and protocol, the contractor's removal, and the clearance assessment. Crawl space access, rebuilding drywall, and replacing flooring are often extra, so ask each company what its number leaves out. The mold remediation cost guide covers the variables in detail.

How to compare Austin quotes fairly

• Give every contractor the same written protocol from your Austin mold inspection, so the quotes cover the same work.
• Look up the contractor's license at tdlr.texas.gov and ask for a certificate of insurance.
• Ask whether drying equipment, disposal, and rebuild are included or priced separately.
• Confirm who books the clearance, and hold final payment until it passes; mold testing in Austin explains that step.

Before the crew arrives

Photograph the damage and the water line before anything is torn out. Creek water is flood damage and belongs to a flood policy; a pipe that burst suddenly is usually a homeowners claim, according to the Texas Department of Insurance. Mixing the two up slows the claim down. Texas lets owners of homes with fewer than 10 units do the work themselves without a license, but at 25 contiguous square feet or more a licensed contractor is the safer and better documented route.

Calling about an Austin job

Tell the company you are connected with what got wet, when, and whether the house is pier-and-beam or slab. They can usually say over the phone whether you need an assessment first and what the next step costs. There is no fee for the call and no obligation to hire.

Removal of 25 contiguous square feet or more in Texas requires a TDLR-licensed mold remediation contractor working from a separate consultant's protocol. Check both licenses at tdlr.texas.gov; owners of homes with fewer than 10 units may do their own work.
