Mold Testing & Inspection in Houston, TX

Your full lab-backed report is ready within one business day of the inspection, or 24 business hours. A Friday afternoon inspection means results Monday morning. Same-day appointments are available across Greater Houston, so if you need an emergency mold inspection, we can usually be at your door within hours and have answers in front of you the next business day.

A typical inspection takes 1 to 2 hours depending on the size of the home. Your assessor performs a full visual inspection, scans for hidden moisture with meters and a thermal imaging camera, and collects air and surface samples for the lab. You are welcome to stay home during the inspection; most homeowners do, and we encourage you to walk along and ask questions. Everything we find goes into a plain-language report with photos.

DIY kits can tell you mold exists, but mold spores exist in every home, so a positive result tells you very little. A kit cannot tell you whether your spore levels are actually elevated, where the moisture source is, or whether the problem is large enough to require licensed remediation. Professional testing compares your indoor samples against an outdoor control and is analyzed by an accredited lab, which is the documentation a landlord, buyer, or remediation contractor will actually accept.

Free mold inspections in Houston almost always come from remediation companies, and the inspection is free because it is a sales visit: the company profits when it finds mold to remove. Texas law separates testing from remediation for exactly this reason. We charge a flat $550 because the assessment is the product, not the pitch, and our only incentive is an accurate result.

Yes. Indoor air quality testing for mold is a core part of every inspection. We collect air samples with a calibrated pump, including an outdoor control sample for comparison, and the lab reports the exact spore types and counts in your air. If you can smell something musty but cannot see anything, air sampling is usually how the problem gets found.

No, and we never will. Under Texas law, mold assessment and mold remediation must be performed by separate companies, and the Texas Department of Licensing and Regulation enforces that separation. We only inspect and test, which means our findings are never influenced by a cleanup bid. If remediation is needed, we write the protocol and you choose any licensed remediator to follow it.

Yes. Mold Testing Houston is a TDLR-licensed mold assessment company (license ACO1245), and every inspection is handled by a certified mold inspector and licensed Mold Assessment Consultant (MAC), the senior credential for assessing mold in Texas. That means you always work with a licensed mold specialist, not a subcontractor, and we are fully insured. If you are wondering who to call for mold testing, Texas law answers that for you: a licensed, independent assessment company. Here is more on who should conduct a mold inspection.

Yes. Every sample is analyzed by EMSL Analytical, an independent, AIHA-LAP accredited laboratory. We do not analyze our own samples, and the lab has no stake in what we find. That two-layer independence, an assessment-only inspector and a third-party accredited lab, is what makes the numbers in your report worth trusting.

When we suspect mold growth behind your walls, we use a minimally invasive approach. We drill a small hole (less than 1 inch by 1 inch) and insert a borescope, a small snake camera, to visually inspect the wall cavity. We can also collect an air sample directly from inside the wall for laboratory analysis, which confirms whether mold is growing where you cannot see it.

Yes, especially in Houston, where humidity and past water damage make hidden mold common in homes of every age. For buyers, testing before closing costs far less than discovering remediation after. For sellers, a clean lab-backed report takes a negotiation weapon off the table before it is raised. We handle pre-purchase inspections, lender-required testing, and clearance testing before closing, with results in one business day for time-sensitive transactions.

If your report confirms mold, the next step depends on the size of the problem. Texas requires a licensed remediation company working from a written protocol when contamination covers 25 contiguous square feet or more. We prepare that mold remediation protocol, you hire any licensed remediator you choose to follow it, and clearance testing afterward verifies the work actually succeeded. Your report lays out these next steps in plain language.
