Frequently Asked Questions
Does Texas require licensing for mold remediation?
Yes for paid work once the published area test is met. 16 Tex. Admin. Code § 78.30 lists 25 contiguous square feet. Occupations Code § 1958.102 lists the same small-area phrase. Search TDLR for an active Mold Remediation Contractor and a separate Mold Assessment Consultant. Do not hire one firm to write the protocol and tear out the same house.
Can the same company do mold assessment and remediation in Texas?
Texas splits those roles. The assessor writes the protocol and later clearance. The remediator follows that protocol. Occupations Code Chapter 1958 is the statute family. If a Houston company offers inspect-and-remove as one package, walk. Independent clearance is how you keep the pass letter honest.
How do I verify a Houston mold contractor TDLR license?
Open TDLR License Search, enter the company name or number, and confirm Active status plus the expiration date. Read disciplinary notes on the same record. Then request the Certificate of Insurance. 16 Tex. Admin. Code § 78.40 lists $1 million per occurrence as the commercial general liability floor for licensed mold work.
What insurance must Texas mold contractors carry?
16 Tex. Admin. Code § 78.40 lists commercial general liability insurance of not less than $1 million per occurrence and requires that coverage for the term of the license. Ask to be named as additional insured on the certificate and call the carrier number on that page. A screenshot of a logo is not verification.
Why is Houston particularly prone to mold?
Bush Intercontinental Airport normals list 51.84 inches of annual rain on the National Weather Service Houston summary. That load, plus long cooling seasons, keeps indoor surfaces wet after storms and AC failures. Humidity is a driver, not a price. Act in the first 24 hours after a leak so a water job does not become a TDLR mold job.
