Is Mold Removal Licensed in Texas?
Yes — Texas has one of the most comprehensive mold licensing frameworks in the country.
Texas requires separate licenses for four roles in mold work, all issued by the Texas Department of Licensing and Regulation (TDLR): Mold Assessment Consultant (MAC), Mold Assessment Technician (MAT), Mold Remediation Contractor (MRC), and Mold Remediation Worker (MRW). Assessment and remediation must be performed by separate license holders — the same individual or company cannot do both on the same project. Post-remediation clearance must be performed by a licensed mold assessor who was not involved in the remediation.
How to Verify a Texas Mold Contractor
Verify any Texas mold contractor’s license through the TDLR license search. Ask for their license number and confirm it is current and in good standing before signing any agreement. Texas homeowners can file complaints with TDLR if a licensed contractor performs substandard or fraudulent work.
TDLR License Search →What to Require Beyond the License
A valid Texas license is the starting point — not the complete picture. Licensed contractors can still perform substandard work or engage in predatory practices. Here is what to verify in addition to license status:
IICRC Certification
The industry standard certification for mold remediation. Verify directly at iicrc.org/certified-firm-search. Ask for the certification number — not just a claim.
Separate assessment and remediation
The company doing the mold removal should never be the same company doing the testing or the clearance test. This conflict of interest is the most common source of inflated scopes and unnecessary work.
Written, itemized estimate
Square footage of containment, materials to be removed, equipment, timeline, and payment terms — all in writing before work starts. Verbal quotes are not contracts.
Independent clearance test
The final step of any legitimate mold removal job is a clearance test by an inspector with no financial connection to the removal company. This is the only way to verify the job was done correctly.
Liability insurance
Ask for a certificate of insurance before work begins. Uninsured contractors leave you exposed if something goes wrong during the job.
The Most Common Mold Scam in Texas
Regardless of licensing status, the most documented mold scam in every market works the same way: a company offers a free inspection, identifies alarming amounts of “toxic black mold,” and pushes for an immediate contract. The same company does the testing, the removal, and the clearance — eliminating any independent check on their findings or their work.
In Texas, a licensed contractor engaging in this practice may be violating state law in addition to committing fraud. Report suspected violations to the relevant licensing authority.
