Texas Mold License Lookup
Search all 9,800+ TDLR mold licenses — remediation companies, assessment consultants, technicians, workers, and labs — by name, license number, city, or county. Updated weekly from official state records.
What this tool tells you
Search the licence records for mold work in the states that issue one — Texas, Florida, New York and Louisiana — by company, contractor or licence number. Six other states license contracting but not mold specifically, and the tool says so rather than returning nothing, because a contractor in California cannot hold a mold licence that does not exist.

Is a mold license required for water damage restoration in Texas?
Water extraction and structural drying alone do not require a state mold license. But if the total affected area exceeds 25 contiguous square feet of mold growth, Texas law requires the work to be performed by a TDLR-licensed mold remediation contractor or company.
Because mold nearly always follows untreated water damage, most reputable restoration companies in Texas hold mold licenses.

Why do assessment and remediation have to be separate companies in Texas?
Texas Occupations Code prohibits a mold assessment company from performing remediation on the same project (and vice versa) to prevent conflicts of interest — the company that diagnoses the problem shouldn't profit from inflating the scope of the fix.
Hire an assessment consultant (MAC/ACO) to write the protocol, then a separate remediation company (RCO) to execute it.
Who do I call right now for water damage?
Call (888) 840-6512. The line is answered 24 hours a day, seven days a week, and connects you with an IICRC-certified water damage restoration company that serves your area.
Describe what you can see — where the water is coming from, how long it has been there, and whether it smells — and the dispatcher routes you to a crew that handles that kind of loss. If the source is a pipe or an appliance, shut the main water valve first; the call itself takes under two minutes.
