Mold Testing & Inspection in Houston, TX

Within one business day of the inspection, or 24 business hours. A Friday afternoon inspection means results Monday morning. That includes the lab work, since every sample goes to EMSL Analytical, an AIHA-LAP accredited laboratory, and comes back with species identified and spore counts measured against an outdoor control rather than a yes or no. There is no rush tier and no expedite fee, because one business day is the standard rather than an upgrade.

One to two hours on site for a typical Houston home, longer for larger properties or homes with several problem areas. That covers the walk-through, moisture mapping, thermal imaging, and sample collection. Lab analysis happens after, and your written report follows within one business day. Full timeline in our guide on how long a mold inspection takes.

Not reliable enough to act on. Most kits use a settle plate, which confirms mold spores are present. Spores are present in every building on earth, so that answer is true everywhere and useful nowhere. What makes a result mean something is the comparison against an outdoor control sample taken at the same property on the same day, and no kit includes one. Kits are also not accepted as documentation by insurers, lenders, courts, or landlords. A kit costs $30 to $80. A flat $550 inspection produces a report those parties will act on.

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.

Yes, and in Houston it is the most common place we find it. Wall cavities hold water from slab leaks, roof leaks, and AC condensate long after the surface feels dry, and paper-faced drywall gives it something to grow on. You cannot see it, so we measure for it. Calibrated moisture meters read through the surface, thermal imaging shows the temperature difference wet material creates, a hygrometer tracks humidity, and a borescope lets us look inside the cavity. Air sampling against an outdoor control catches what the tools cannot reach.

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.

Check the license. Texas requires mold assessment companies and consultants to be licensed by TDLR. Mold Testing Houston operates under company license ACO1245, and every inspector holds an individual Mold Assessment Consultant license. Verify any company on the TDLR license search rather than taking their word for it, including ours.

Avoid the remediation conflict. Hire a company that only tests and does not sell the cleanup, because a company that fixes what it finds has a financial reason to find more. We have been assessment-only since 2017 and never bid on remediation.

Verify the lab. Samples should go to an independent accredited laboratory. Ours go to EMSL Analytical, AIHA-LAP accredited, with no financial relationship to us.

Confirm insurance. Texas requires licensed assessment companies to carry at least $1 million in general liability coverage. Ask any company to confirm what they hold.

Ask about the tools. Houston's humidity and storm history mean most problems are hidden. Ask whether they use thermal imaging and calibrated moisture meters to find water behind walls. We use both, plus a hygrometer and a borescope.
