What Actually Drives Mold Remediation Costs in Texas
Texas has the most prescriptive mold law of any large state, and it changes the price of every job above 25 square feet. Texas Occupations Code Chapter 1958 and the Texas Mold Assessment and Remediation Rules, administered by the Texas Department of Licensing and Regulation, require licensed mold assessment consultants and licensed mold remediation contractors, and — critically — prohibit the same company from both assessing and remediating the same project. You will be paying two firms, and that is by design.
The 25-square-foot threshold is the number to remember. Below 25 contiguous square feet of affected material, a homeowner or an unlicensed handyman may perform the work. At or above 25 square feet, the project must be scoped by a licensed assessor with a written remediation protocol, performed by a licensed remediation contractor to that protocol, and cleared by the assessor afterwards. Expect $500–$1,200 for the assessment and protocol, and a separate remediation bid built to it.
The rules exist because Texas was the epicenter of the early-2000s mold insurance crisis. Claim severity rose so sharply that carriers restricted mold coverage statewide and the state responded with licensing rather than with coverage mandates. That history is why Texas mold policies remain capped and why the documentation requirements are unusually strict.
Texas Licensing, Permits & Rules That Change the Price
The 25 square foot licensing threshold
Under the Texas Mold Assessment and Remediation Rules (16 TAC Chapter 78), work on 25 or more contiguous square feet of mold-affected material requires TDLR-licensed personnel. Licensees are searchable on the TDLR site — check the license before the deposit, not after.
A licensed remediation contractor must also post a notice at the job site and submit a work plan. If nobody posted a sign on your project, the job is likely non-compliant, and a non-compliant remediation can compromise both your insurance claim and your future disclosure position.
Separation of assessment and remediation
Texas prohibits a licensed mold assessment consultant and the remediation contractor from having a financial interest in each other on the same project. This eliminates the classic conflict where the party diagnosing the problem also sells the cure. Practically it adds roughly $700–$1,500 to a mid-size project and typically saves multiples of that by right-sizing the scope.
Certificate of Mold Damage Remediation (form MDR-1)
For any project requiring a licensed contractor, the assessor and remediator must issue a Certificate of Mold Damage Remediation to the property owner within 10 days of completion. Two things follow. First, Texas Insurance Code §544.354 bars an insurer from denying coverage or raising your premium based on prior mold damage if you hold a certificate showing the property was remediated. Second, Property Code §5.008 requires sellers to disclose known mold, and the certificate is the document that resolves the buyer's question. Do not accept a completed remediation without it.
Mold Remediation Costs by Texas Metro
| Metro area | Typical project range | What drives the difference |
|---|---|---|
| Houston | $2,200 – $13,500 | Gulf humidity plus slab construction; the highest volume mold market in the state. |
| Austin | $2,100 – $11,500 | Highest licensed-contractor rates; limited assessor availability lengthens scheduling. |
| Dallas–Fort Worth | $1,900 – $10,500 | Drier climate; most jobs originate from plumbing leaks rather than ambient humidity. |
| San Antonio | $1,700 – $9,000 | Competitive pricing with adequate licensed capacity. |
| Corpus Christi / Coastal Bend | $1,800 – $10,000 | Post-storm surges in demand can double lead times and lift pricing seasonally. |
Ranges reflect complete projects including mitigation and typical repairs. Your quote depends on affected area, water category and how quickly work started.
Texas mold coverage after the 2003 reforms
Texas carriers are permitted to exclude mold remediation, and most standard HO-A and HO-B forms in the state limit fungi coverage to $5,000–$10,000 unless you purchase a buy-back. Ask specifically for the "limited fungi, wet or dry rot, or bacteria" endorsement limit on your declarations page.
Coverage generally requires the mold to result from a covered, sudden water loss. Mold caused by long-term humidity, condensation or deferred repair is excluded in virtually every Texas form.
Texas Insurance Code §544.354 is your protection after the fact: with a Certificate of Mold Damage Remediation in hand, a carrier may not refuse to issue or renew, or charge more, based on that prior mold damage.

Texas Insurance Considerations
Mold coverage varies significantly. Many policies cap mold remediation at $5,000-$25,000 or exclude it entirely. Texas requires separate flood insurance for storm surge and flooding. Wind damage coverage has specific requirements along the coast.
