How to Verify a Texas Mold Contractor License

Go to tdlr.texas.gov/LicenseSearch

Search by contractor company name or individual's name

Confirm license type is 'Mold Remediation Contractor' or 'Mold Assessment Consultant'

Verify status shows 'Active' with a future expiration date

Check for any disciplinary actions in the same record

Cross-check IICRC certification at iicrc.org/find-an-iicrc-certified-firm

Lookup tip: When searching TDLR, use the company's full legal name — not their DBA (doing business as) name. If in doubt, ask the contractor for their TDLR license number directly.

Texas has no separate water damage restoration license — only mold work requires a TDLR license. Structural reconstruction requires a general contractor registered with the Texas Secretary of State.

IICRC WRT (Water Restoration Technician) and ASD (Applied Structural Drying) certifications are the industry standard for extraction and drying. Not required by Texas law but recognized by all major TX insurers as proof of competency.

Key Facts — Texas Contractor Licensing

Mold work requires a TDLR license — a general contractor license alone is not sufficient
Texas does not require a separate state license for water damage extraction and drying — only the mold remediation phase is licensed
TDLR mold contractors must carry at least $300,000 general liability insurance per occurrence
The same company cannot hold both a Mold Assessment and Mold Remediation license in TX — these must be separate firms

State fact: Texas processes more mold remediation licenses than any other state due to Hurricane Harvey (2017) and the February 2021 freeze event.

Penalty: Performing mold remediation or mold assessment without a TDLR license is a Class A misdemeanor in Texas — up to $25,000 fine per violation under TX Occupations Code §1958.

License Verification — Houston, Texas FAQ

Do water damage contractors need a license in Houston, Texas?

Water damage extraction and drying itself does not require a separate state license in Texas. The mold remediation phase does: Texas Department of Licensing and Regulation (TDLR) issues it, and doing mold work without it is a violation the state can act on.

Verify the Texas Department of Licensing and Regulation license before work begins, and ask separately for IICRC certification — WRT for drying, AMRT for mold — which is the credential that speaks to the work rather than the paperwork.
