What the seven license categories mean
Texas splits mold work into assessment (inspecting, sampling, writing the protocol) and remediation (the removal itself), and licenses companies and individuals separately in each. The split is the consumer-relevant part: on a given project, the assessor and the remediator are meant to be different parties — the conflict-of-interest rule explained here.

Not in Texas?
A handful of other states license mold work: Florida (DBPR licenses mold assessors and remediators, with a similar separation of roles), New York (Department of Labor) and Louisiana among them. We have not yet verified those states' bulk data, so we link the official lookups rather than embedding records we can't vouch for: Florida DBPR license search · New York DOL mold program · Louisiana contractor search. In states with no mold licensing, ask for the certifications and insurance the quote claims, in writing.
Common questions
Who needs a mold license in Texas?
Texas licenses the people and companies that assess or remediate mold in buildings, under Texas Occupations Code chapter 1958 and TDLR's mold rules. Small projects fall under an exemption threshold, and homeowners working on their own homes are treated differently — but a company charging you to remediate a sizable problem should appear in this register. If a name is missing, confirm against TDLR's official search before concluding anything.
The company on my quote isn't in the register. What does that mean?
First, search fewer words: the register lists formal legal names, which often differ from the brand on the truck. Ask the company for its TDLR license number outright; licensees are used to the question. If there is genuinely no license behind a substantial remediation quote, that is a material fact for your decision, and worth confirming on TDLR's official search.
What's the difference between an assessment license and a remediation license?
Assessment licensees inspect and write the protocol; remediation licensees do the removal. Texas law deliberately separates the roles on a given project, so the party telling you how bad it is should generally not be the party selling you the fix for it. The details, with the statute cited, are on our inspection and testing page.
How fresh is this data?
The register is re-downloaded from TDLR's public bulk files at every site build and stamped with its date — currently 2026-08-31. Between builds, TDLR's own license search is always the authoritative, real-time source.
Does a CURRENT license mean the company is good?
No. It means the state's baseline requirements (training, exam, insurance where required) are met and the license hasn't lapsed. It is a floor, not a review score. An EXPIRED status on an active quote, on the other hand, is a concrete, checkable problem.
