Mold Testing & Inspection in Texas
Texas law separates mold assessment from mold remediation. We work on the assessment side only — we test, we report, and we never bid on the repair.
- Licensed Texas mold assessors (TDLR)
- Testing only — never remediation
- Free estimates statewide

2. We match you with an assessor
You're connected with a TDLR-licensed, testing-only mold assessor covering your part of Texas.
3. Get lab-backed results
A written report with lab analysis, usually within a couple of days — yours to act on however you choose.
What Mold Testing Costs in Texas
Across Texas metros, a standard mold inspection with two air samples and lab analysis typically runs $295 to $400. Dallas usually lands around $309 to $384, with Austin trending slightly higher and the other metros in a similar band. Larger homes and difficult crawl space access push the total up.

Why Texas Homes Get Mold
Expansive Clay Soil and Slab Leaks
Much of Texas sits on clay that swells when wet and shrinks when dry. That constant movement stresses slab foundations and the plumbing running through them.
Why it matters: A slow slab leak can run for months beneath flooring before anyone notices, feeding mold the whole time.
In Texas: Foundation repair is routine across North and Central Texas. If a home has been leveled, the plumbing underneath is worth checking too.
Gulf Humidity and Storm Flooding
The closer you get to the coast, the less chance a home has to dry out. Hurricanes and tropical storms push water into houses that were never designed to get wet.
Why it matters: Post-flood repairs are often cosmetic. New drywall over damp framing hides a problem rather than fixing it.
In Texas: Houston and the Gulf Coast carry the heaviest exposure, but flash flooding reaches well inland along the I-35 corridor.
Year-Round Air Conditioning
Texas summers mean months of continuous AC against high outdoor humidity, creating condensation inside wall cavities and around ductwork.
Why it matters: This is hidden mold by definition — it grows behind drywall and inside the system that moves air through the whole house.
In Texas: Oversized AC units are common here. They cool fast without running long enough to pull humidity out, leaving damp air behind.
Unbiased
We only test. We never sell remediation, so there's no incentive to find a problem you don't have.
Licensed
Every assessor in our Texas network holds a current TDLR mold assessment license.
Why Independence Matters More in Texas
Texas is one of the states that wrote this into law. The Texas Department of Licensing and Regulation issues separate credentials for mold assessment and mold remediation, and with limited exceptions the same company cannot do both on the same property. The reasoning is simple: a company paid to find mold that also profits from removing it has an obvious conflict.
Assessment, not remediation
We sit on the assessment side of the line Texas law draws, so our findings aren't a sales pitch.
TDLR-licensed assessors
Verifiable licenses — worth checking for anyone you hire, ours or not.
Written, lab-backed reports
Documentation you can hand to an insurer, a landlord, or a buyer.
Mold Testing in Texas: Common Questions
What is the mold law in Texas?
Texas regulates mold work through the Texas Department of Licensing and Regulation. Mold assessment and mold remediation require separate licenses, and with limited exceptions the same company cannot both assess and remediate the same property. Small jobs under a defined size threshold are exempt from some requirements. The separation exists because a company that profits from remediation has an incentive to find more mold.
How much does mold testing cost in Texas?
A standard inspection with two air samples and lab analysis typically runs $300 to $500 across Texas metros. Dallas often falls around $309 to $384. Individual lab samples cost $75 to $125 each, and larger or harder-to-access homes cost more.
Do I need a licensed mold assessor in Texas?
For most residential mold assessment work, yes — Texas requires a TDLR license. You can verify any assessor's license through the TDLR license search before hiring. We only work with assessors who hold a current license.
Do you do mold removal in Texas?
No. We only perform testing and assessment, which is both our model and, for the same property, what Texas law contemplates. If your results call for remediation, you take the report to a licensed remediation contractor of your choosing.

- Fort Worth mold testing — Tarrant County foundation movement and pier-and-beam crawl spaces in Fairmount and the Near Southside
- Houston mold testing — Gulf humidity, flood-history homes, and independent pre-purchase testing in flood-affected neighborhoods
- Austin mold testing — moisture problems in fast-built new construction, flash-flood exposure, and rental disputes near UT
- San Antonio mold testing — heavy AC condensation, older homes in King William and Monte Vista, and pre-lease testing for military families
What mold testing costs across Texas
| Metro | Typical range (inspection + 2 samples) |
|---|---|
| Dallas | $309–$384 |
| Fort Worth | $295–$375 |
| Houston | $299–$389 |
| Austin | $315–$395 |
| San Antonio | $295–$375 |
Sample count drives the price far more than metro does. A two-sample job and a six-sample job take similar labor; the lab work is what scales. For the full national breakdown, see our guide to what mold testing costs.
Texas mold assessor licensing, briefly
Texas issues two relevant credentials through TDLR: Mold Assessment Consultant and Mold Assessment Technician on the testing side, and Mold Remediation Contractor on the removal side. With limited exceptions, a company cannot hold both roles on the same property.
That legal separation is unusual and worth understanding, because it tells you what to expect from a legitimate Texas provider. If a company offers to both test your home and remediate what it finds, ask how they square that with state licensing rules before you hire them.
