TDLR-LICENSED · ACO1245
In Texas, only a TDLR-licensed mold assessor can conduct an independent inspection that holds up for insurance, real estate, or remediation clearance. Here’s how to make sure you’re hiring the right one.
When it comes to mold in your home or building, identifying and addressing it properly is critical to maintaining a healthy indoor environment. But not everyone is equipped to recognize and diagnose mold problems effectively.
A mold inspection should always be conducted by a qualified professional, specifically, a certified industrial hygienist or a licensed mold inspector.
These experts bring both technical expertise and specialized tools that ensure inspections are thorough, accurate, and compliant with safety standards.
Why Texas Law Matters
Under the Texas Mold Assessors and Remediators Program (TMARP), administered by the Texas Department of Licensing and Regulation (TDLR), a licensed mold assessor and a licensed mold remediator are legally prohibited from being the same company on the same job. The state created this rule specifically to protect homeowners from conflicts of interest.
If a company offers to both inspect and remove your mold under one contract, they are either operating outside the law or steering you toward a remediation bill that benefits them. An independent, assessment-only inspector has no financial reason to find more mold than is actually there.
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.
Here’s what makes a professional mold inspector the right choice:
Certified Industrial Hygienists (CIHs) and licensed mold inspectors must meet strict education and training standards. CIHs are credentialed through the American Board of Industrial Hygiene. In Texas, the relevant TDLR credentials are the Mold Assessment Consultant (MAC), Mold Assessment Technician (MAT), and Certified Mold Remediator (CMR) designations.
Trained inspectors understand airflow patterns, moisture intrusion, and building materials, which are critical in identifying mold sources, not just symptoms.
From thermal imaging cameras to moisture meters and air sampling pumps, professionals use advanced tools to detect mold that is invisible to the eye.
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.
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.
An independent, assessment-only firm has only one job: to tell you what is actually there, document it for insurance or real estate purposes, and write a protocol another licensed remediator can follow if needed. We do not sell remediation, so the inspection result is the deliverable, not a sales lead.
You should consider hiring a certified mold inspector if:
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.

FREQUENTLY ASKED QUESTIONS
For any building assessment connected to insurance claims, real estate transactions, or remediation work, Texas law requires a TDLR-licensed mold assessor. For private peace-of-mind testing in a home you own, a licensed assessor is not legally required but is strongly recommended for reliable, lab-backed results.
A home inspector can flag suspected mold visually, but cannot legally take samples or write a remediation protocol in Texas. Only a TDLR-licensed mold assessor can collect air or surface samples, send them to an accredited lab, and produce a report that holds up for insurance, real estate, or remediation clearance.
No. Under TMARP, a TDLR-licensed mold assessor and a TDLR-licensed mold remediator cannot be the same company on the same project. This is a state-level rule designed to prevent conflicts of interest between testing and removal services.
Most labs return results in 3 to 5 business days. Mold Testing Houston delivers full lab analysis and a written report within 24 hours of the on-site inspection, which is the fastest turnaround in the Houston market.
Mold Testing Houston charges a flat $550 for a residential mold inspection, including lab samples and the written report. There are no surprise add-ons, and no upsell to remediation, since we do not perform it.
Document what you are seeing or smelling with photos and notes. If anyone in the home is experiencing respiratory symptoms, consult a medical professional. Then contact a TDLR-licensed independent assessor for a proper inspection before any cleanup, since disturbing visible mold can spread spores and complicate testing.
Choosing the right professional to conduct a mold inspection is crucial to ensuring both your health and the long-term integrity of your home or business.
Whether you opt for a certified industrial hygienist or a licensed mold inspector, make sure they are properly credentialed and experienced. Mold may be common, but its effects can be serious. Leave the inspection to those who know exactly what to look for, and confirm their TDLR license number before anyone steps onto your property.
