Every Texas and New York mold license, searchable: 14,427 licensees in good standing across twelve categories, straight from the states' own files (Texas as of 2026-10-12, New York as of 2026-10-12). Type the company or person on your quote. If they're doing licensed-scale mold work in either state, they should be here.
What the Texas 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.

What the New York license categories mean
New York runs the same separation under Labor Law Article 32, and states it just as bluntly: §936 provides that “no licensee shall perform both mold assessment and mold remediation on the same property,” and bars any person owning an interest in both licensees on the same property. It goes one step further than Texas on paperwork — §945 requires the assessment licensee to “prepare a mold remediation plan that is specific to each remediation project and provide the plan to the client before the remediation begins.”
| Category | Active | What they do |
|---|---|---|
| Mold Assessment Contractor | 802 | Business licensed to assess mold and write the remediation plan — full register |
| Mold Remediation Contractor | 946 | Business licensed to perform the removal — full register |
| Mold Assessor | 1780 | Individual licensed to inspect and assess |
| Mold Supervisor | 1897 | Individual supervising remediation projects |
| Mold Abatement Worker | 2035 | Individual performing abatement labor |
Sources: N.Y. Labor Law §936 · §945 · NYSDOL mold program (all accessed 2026-09-01). Licence data as of 2026-10-12. New York publishes a rolling four-year window, so a licence that lapsed longer ago than that is absent rather than listed as expired.
Neither Texas nor New York?
Other states license mold work — Florida (DBPR licenses mold assessors and remediators, with a similar separation of roles) and Louisiana among them. We have not verified bulk data for those, and we won't embed records we can't vouch for, so the official lookups are the honest answer: Florida DBPR license search · Louisiana contractor search. In states with no mold licensing at all, 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 2026-10-12. 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.
