If the Mold Followed a Leak
Stop the water at the fixture valve or the main, cut power to wet rooms at the breaker if you can reach the panel safely, move what you can out of the water, and photograph everything before it is touched. Water that has reached carpet pad, drywall or a subfloor is a same-day restoration call rather than a cleanup: mold can establish on wet materials within 24–48 hours, and every hour of delay moves materials from "dry it" to "replace it."
Before You Sign Anything
Ask for a written scope and the pricing basis, who is fixing the water source and when, and what the moisture readings are — a company that does not take readings is not drying. Sudden, accidental water damage (a burst pipe, a failed supply line, an appliance leak) is usually covered by homeowners insurance; long-term leaks, neglected maintenance and rising outside water usually are not. Document first, then call the restoration company, then the insurer.

Frequently Asked Questions
Does Texas require a license for mold remediation?
YesTexas licenses mold work through the Texas Department of Licensing and Regulation (TDLR).
The credentials to look for: Mold Assessment Consultant (MAC), Mold Remediation Contractor (MRC), Mold Assessment Technician (MAT), Mold Remediation Worker (MRW). 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.
How do I verify a company's mold license in Texas?
Use the official TDLR License Search — it's public and takes about two minutes: search the company's legal name, confirm the license type matches the work (Mold Assessment Consultant (MAC)), check the status is Active with a future expiration, and scan the same record for disciplinary actions.
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.
What happens if a company works without a license in Texas?
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. For you it also matters practically: insurers and future buyers treat unlicensed remediation paperwork as barely better than none.
Is a water damage restoration license different from a mold license in Texas?
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. For the extraction-and-drying phase, the industry standard to ask about is IICRC certification.
Is IICRC certification the same as a state license?
NoThey answer different questions. 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. The strong hire holds both: the state credential you can verify in the registry, and IICRC-certified technicians on your specific job.
I need a verified company fast — what's the shortcut?
One call: describe what you're dealing with and a certified pro serving your ZIP answers, with costs explained before any work starts. Then run their company name through the TDLR License Search while you're still on the phone — a legitimate Texas pro will happily wait the ninety seconds it takes.
