What Is a Certified Mold Inspector? TDLR Licensing in Houston Explained
A certified mold inspector in Texas is more accurately described as a TDLR-licensed mold assessment professional, because Texas regulates this work through state licensing rather than informal certification. Knowing the difference protects you from hiring someone who lacks the credentials the state actually requires. At Mold Testing Houston, we have operated as a licensed assessment company since 2017 under TDLR license ACO1245, with every inspection handled by a licensed consultant.
This guide explains how mold inspector licensing works in Texas, what the different credentials mean, and how to verify that the company you hire is properly licensed. If you want a licensed independent inspection now, learn more about who should conduct a mold inspection and book directly.
What Licenses Does a Mold Inspector Need in Texas?
A mold inspector in Texas needs a TDLR license to legally assess mold, and the type depends on whether it is an individual or a company. The state separates these credentials clearly.
- Mold Assessment Consultant (MAC). The senior individual license for assessing mold. A consultant can inspect, develop sampling plans, and write remediation protocols.
- Mold Assessment Technician. An individual license that works under a consultant to record observations and collect samples.
- Mold Assessment Company. The business-entity license that employs assessment personnel and issues formal assessment reports. This is the company-level credential.
Mold Testing Houston holds Mold Assessment Company license ACO1245, and our inspectors carry the individual Mold Assessment Consultant credential, which is the senior assessment license in Texas.
Is “Certified” the Same as “Licensed” in Texas?
No, “certified” is not the same as “licensed” in Texas, and the distinction matters. Anyone can claim to be a “certified” mold inspector through a private course, but only a TDLR license legally authorizes someone to assess mold and issue reports in Texas.
This is one of the most common points of confusion homeowners run into. A company advertising “certified inspectors” may or may not hold the state license the work actually requires. When you are vetting a mold inspector in Houston, the credential to ask about is the TDLR license, not a certification. You can confirm any company or individual through the TDLR license search tool, which lists every currently licensed mold professional in the state.
How Do You Verify a Mold Inspector’s License?
You verify a mold inspector’s license by searching the TDLR license database using the company name or license number. It takes a minute and confirms the credential is current.
Ask the inspector for their TDLR license number before you hire them, then look it up. A legitimate, licensed company will provide it without hesitation. For Mold Testing Houston, the company license is ACO1245, and you can verify it directly through TDLR. If a company cannot or will not give you a license number, that is a reason to keep looking.
Why Should Your Inspector Be Independent?
Your inspector should be independent because Texas prohibits the same company from performing both mold assessment and remediation on a project, specifically to prevent conflicts of interest. An inspector who also sells remediation has a financial reason to find more mold than may exist.
An independent, testing-only company gives you an unbiased result. We assess and report, and that is all, so there is no removal service waiting on the back end to influence the findings. That independence is exactly why the separation exists in Texas law, and it is the core reason to choose a dedicated assessment company for your inspection.
What Does a Licensed Mold Inspection Include?
A licensed mold inspection includes a visual assessment, moisture and humidity readings, air and surface sampling, and a written lab report. The license ensures the work meets Texas standards and that the report is legitimate.
Hiring a licensed company means the inspection is performed correctly, the lab analysis is properly handled, and the report you receive will hold up for insurance, real estate, or legal purposes. The credential is not a formality. It is your assurance that the inspection was done by someone the state has authorized to do it.
