How to Hire a Mold Contractor in Texas: 10 Questions to Ask

Updated October 7, 2026 · 1 min read

A checklist for verifying licenses, comparing written scopes and avoiding the common mold-remediation scams in Texas.

Mold remediation is lightly understood by buyers, which makes it easy to oversell. Use these ten questions to separate real operators from fogging-and-invoice outfits.

1. What is your TDLR license number? Look it up yourself on TDLR's license search; check that it's active and for the right license type.
2. Is a separate assessor writing the protocol? On 25+ contiguous sq ft, Texas requires it. See the law explained.
3. Where is the moisture coming from, and who fixes it? If the answer is "we'll treat it", that's not a plan.
4. What will be removed vs. cleaned? Expect porous materials to be removed. Ask for it by room.
5. How will you contain the work? Look for plastic barriers, negative air with HEPA filtration and protection of HVAC returns.
6. What does "done" mean? Clearance testing by the assessor, not the remediator's own opinion.
7. Will I get the Certificate of Mold Damage Remediation? It's issued to the owner on qualifying projects.
8. Proof of insurance and workers' compensation? Ask for certificates, not promises.
9. Is the price itemized? Compare line by line. A low price that omits containment isn't low.
10. What warranty do you provide, and what does it cover? Warranty on a mold job should be tied to moisture control; a warranty "against mold returning" with no source fix is marketing.

Comparing three bids

Put the scopes side by side. Differences usually come from containment, whether demolition is included, and whether clearance testing is included. See typical cost ranges for context.

Scams to avoid

• Door-to-door "free inspections" after a storm
• "Mold test" that always finds mold: unusual lab fees and pressure to sign the same day
• Fogging or encapsulation only
• Large upfront deposits with no contract
• No license number in the ad (a violation of Texas rules)
