Choosing a mold inspector in Houston comes down to one question: is the person testing your home independent from whoever profits from the cleanup? In Texas, that answer is the law.
The short answer
In Texas, you call a TDLR-licensed mold assessment company.
Not a remediation company, and not a general home inspector. Texas law requires the company that tests your home and the company that removes the mold to be two separate businesses once contamination passes 25 contiguous square feet. That separation is the point: an assessor with no cleanup to sell has nothing riding on what the lab finds. Mold Testing Houston holds Mold Assessment Company License ACO1245 and performs assessment only.
Who Can Inspect
In Texas, a mold inspection on a property of any meaningful size must be performed by an independent, TDLR-licensed mold assessor. 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. 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. If a company cannot hand you a license number, that is your answer.
You may also hear that an industrial hygienist can test for mold, and technically one can. Here is how the options actually compare for a Houston homeowner.
Certified at the state level and trained specifically in mold detection. In Texas they hold a Mold Assessment Consultant (MAC) license, the senior credential. Mold Testing Houston's assessors hold MAC licenses under Company License ACO1245.
A specialist in environmental health and indoor air quality. Valuable in complex situations such as large commercial buildings or properties with ongoing, unexplained health complaints, but more than a typical Houston home needs.
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.
Most Houston homeowners start the same way: a musty smell in one room, a stain that appeared after a storm, or a home inspector who wrote “possible microbial growth” and moved on. A retail test kit will confirm what you already know, that mold spores exist in your house, because they exist in every house. What it cannot tell you is whether your indoor levels are actually elevated against the outdoor air, where the moisture is coming from, or whether the affected area crosses the 25 contiguous square feet that triggers licensed remediation under Texas law.
That is the gap a licensed assessment fills. An assessor traces the moisture to its source, measures what is actually airborne against an outdoor control sample, and produces a document a buyer, a lender, an adjuster, or a remediation contractor will accept. In Houston, where slab foundations, year-round humidity, and AC condensate drive most of what we find, the source is usually somewhere the homeowner has not looked.
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 EMSL Analytical, an AIHA-LAP accredited lab, for analysis, rather than being read on the spot by someone with cleanup to sell.
Watch Out For This
Across Houston, plenty of remediation companies advertise "free mold inspections." On paper that sounds homeowner-friendly. 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.
Mold Testing Houston only does assessment, so our only product is an accurate answer. Sometimes that answer is good news: the air is clean and you do not need anyone at all. We are just as glad to deliver that as a failing result.
The most common reasons Houston homeowners book an independent inspection:
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 we have stayed assessment-only: we identify mold, document it, run samples through EMSL Analytical (an AIHA-LAP accredited lab), and write the report and, where it is required, the remediation protocol that a separate licensed contractor then follows.
Pricing is a flat $550 for a standard inspection covering up to two samples, with any additional samples at $85 each and collected only with your approval. Your written report lands within one business day 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.
FREQUENTLY ASKED QUESTIONS
Look for a current TDLR license (verify the number), an assessment-only company with no remediation to sell, use of an accredited lab, and clear flat pricing. Mold Testing Houston meets all four: TDLR ACO1245, assessment-only, accredited lab, and a flat $550 fee.
No. Texas law requires the licensed assessor and the licensed remediation contractor to be separate parties on the same project once contamination passes 25 contiguous square feet, specifically to prevent conflicts of interest.
Yes. Texas licenses mold assessors through the TDLR. Always ask for and verify the license number before booking. Mold Testing Houston holds license ACO1245.
Mold Testing Houston charges a flat $550 for a standard inspection, including the on-site visit, EMSL Analytical (AIHA-LAP accredited) lab analysis, and the written report. Mold remediation protocols start at $750 and scale with the number of remediated areas.
In Texas, mold assessment is licensed work. A TDLR-licensed Mold Assessment Consultant or Mold Assessment Technician can inspect your property, collect samples, and write the report. A general home inspector can flag visible moisture or suspected growth during a standard inspection, but interpreting lab results and writing an assessment or remediation protocol is licensed work they are not credentialed to perform. A remediation contractor can inspect, but not on a project they will also be paid to clean up. Mold Testing Houston operates under Mold Assessment Company License ACO1245 and performs assessment only.
The two you will actually be offered are an assessment and a clearance test. An assessment comes first: it locates the moisture source, documents the affected areas, identifies what is growing, and determines whether licensed remediation is required. A clearance test comes last, after remediation, and independently verifies the work succeeded before you move back in. Within an assessment itself, samples split between air, collected with a spore trap and compared against an outdoor control, and surface samples taken by swab or tape lift from visible growth.
Some do, and the structure invites it. When the company inspecting your home is also bidding on the cleanup, a larger finding means a larger contract. That is exactly why Texas requires the assessor and the remediator to be separate businesses once contamination passes 25 contiguous square feet. Plenty of remediation companies are honest operators, but you should not have to depend on that. Ask whoever inspects your home whether they profit from the repair. If the answer is yes, get an independent assessment before you sign anything.
Hire from the protocol, not from a sales pitch. Once an independent assessment is done, you have a written remediation protocol that specifies the scope of work, and every contractor should quote directly against it so you can compare bids line by line instead of comparing three different descriptions of the same job. Confirm the company holds a current TDLR mold remediation contractor license, and confirm they will allow independent clearance testing when they finish. A remediator who resists third-party clearance is telling you something useful. Because Mold Testing Houston never performs remediation, the protocol we write is yours to shop to any licensed contractor you choose.
The on-site inspection takes about 60 to 90 minutes, and your written lab report is delivered within one business day of sampling.
Because an independent, assessment-only inspector has no remediation to sell, the findings are not shaped by a financial incentive to find or inflate a problem. You get an honest answer you can act on.
