INDEPENDENT MOLD ASSESSMENT · TDLR ACO1245
Choosing a mold inspector in Houston really comes down to one question Texas law already answers for you: is the person testing your home financially independent from whoever would profit from the cleanup? Mold Testing Houston has been an independent, assessment-only firm since 2017, licensed by the Texas Department of Licensing and Regulation (TDLR ACO1245). We inspect, sample, and report. We do not perform remediation, so the findings you get are the findings, not a setup for work we would bill you for.
When mold turns up in a Houston home, the question that matters most is not just whether you have it, but who you trust to test for it. Plenty of companies offer mold inspections, but not all of them are licensed or independent enough to give you an answer you can rely on.
In Texas, a mold inspection should be performed by an independent, TDLR-licensed mold assessor. Mold Testing Houston holds Mold Assessment Company License ACO1245 and does assessment only. You may also hear that an industrial hygienist can test for mold, and technically one can, but for a Houston homeowner the licensed, practical, and conflict-free choice is a TDLR mold assessment consultant, not a remediation company offering to inspect its own future work.
That independence is the whole point. An inspector who also sells the cleanup has a reason to find a problem, and to find a big one. An independent assessor has nothing riding on the result, so the findings are the findings: sampled, run through an accredited lab, and delivered as a written report within 24 hours.
Why Texas Law Matters
In Texas, the company that inspects your home for mold and the company that removes it have to be two separate businesses. The Texas Mold Assessment and Remediation Rules, enforced by the Texas Department of Licensing and Regulation require a licensed mold assessor and a licensed mold remediation contractor to be different parties on the same project once contamination passes 25 contiguous square feet. The reason is simple. An inspector who also sells remediation has a financial reason to find a problem, and to find a big one. An independent assessor like Mold Testing Houston (TDLR ACO1245) has no cleanup to sell, so nothing rides on the result. When you are working out how to find a mold inspector you can actually trust, this separation is the first thing to confirm.
A TDLR-licensed mold assessor conducts an independent inspection, writes a third-party remediation protocol, and a separate TDLR-licensed remediator handles removal under a different contract.
A single company sells you both the inspection and the remediation for the same project. This is a TDLR violation and exists to protect you from upsold remediation work.
Many homeowners are tempted to investigate mold issues themselves or rely on basic test kits. While these DIY approaches may seem cost-effective, they often fail to detect hidden mold or provide false positives.
Professionals, on the other hand, use science-based methods and have deep knowledge of building systems and environmental health. They will provide detailed instructions and protocol to follow if mold is found during their inspection.
A few things separate a qualified Houston mold inspector from a handyman with a moisture meter:
In Texas, mold assessment is licensed work, and the credential that matters is the TDLR Mold Assessment Consultant. Mold Testing Houston holds Mold Assessment Company License ACO1245. Just as important as the license is independence: an assessor who does assessment only, and never the remediation, has no financial reason to inflate what they find.
A skilled assessor reads the home, not just a meter. They understand airflow, moisture intrusion, and how Houston's humidity, slab-on-grade foundations, and AC condensation drive mold, so they trace the source instead of chasing the symptom.
Thermal imaging, moisture meters, and air-sampling pumps surface mold you cannot see. Just as important, the samples go to an independent, accredited lab for analysis, rather than being read on the spot by someone with cleanup to sell.
Not everyone who offers mold testing is licensed to do it. In Texas, a mold assessment on a property of any meaningful size must be performed by a TDLR-licensed mold assessor. A general home inspector can flag visible moisture or suspected mold during a standard inspection, but interpreting samples, writing the assessment, and producing the report that guides remediation is licensed work. Our inspectors are licensed assessors, not remediation salespeople. If a company cannot hand you a license number, that is your answer.
These are specialists in environmental health who assess and manage risks associated with indoor air quality. In mold inspections, CIHs can:
These professionals are certified at the state level and are trained specifically in mold detection and analysis. In Texas, they hold a TDLR Mold Assessment Consultant (MAC) or Technician (MAT) license. They typically:
Watch Out For This
Across Houston, plenty of remediation companies advertise “free mold inspections.” On paper, that sounds like a homeowner-friendly offer. In practice, it almost always means the inspection is being done by the same company that wants to be paid to remove the mold. The inspection is the lead, the remediation is the sale.
That creates a structural conflict of interest. If finding mold leads to a $5,000 remediation contract, the inspector has an incentive to find mold, even when the situation could be resolved with simpler moisture control. It is also why Texas separates the two roles under law in the first place.
Mold Testing Houston only does assessment, our only product is an accurate answer. Sometimes that answer is good news, that the air is clean and you do not need anyone at all, and we are just as glad to deliver that as a failing result.
The most common reasons Houston homeowners book an independent inspection:
-Buying or selling a home, especially one that flooded during Harvey or sits in a flood-prone part of the metro.
-After a roof leak, plumbing leak, slab leak, or AC condensation issue, the moisture sources behind most Houston mold.
-Visible growth or a persistent musty smell with no obvious source.
-Health symptoms such as congestion, headaches, or irritation that ease when you leave the house.
After remediation, to confirm independently that the work actually cleared the problem before you move back in.
If any of the above describe you, contact a TDLR-licensed mold assessor before the issue spreads. Mold-related health concerns should be evaluated by a medical professional in parallel with any building assessment.
MEET YOUR INDEPENDENT MOLD ASSESSOR
We built Mold Testing Houston around independence on purpose. Since 2017, nine years serving the Houston area, we have stayed assessment-only: we identify mold, document it, run samples through an accredited lab, and write the report and, where it is required, the remediation protocol that a separate licensed contractor then follows.
We never bid on the cleanup. Pricing is a flat $550 for a standard inspection with no per-sample upcharges, and your written report lands within 24 hours of sampling. We hold TDLR Mold Assessment Company License ACO1245 and serve Houston and the surrounding suburbs, from the inner Loop out to Katy, The Woodlands, Conroe, and beyond.
