Hiring a mold inspector in Texas has an extra step the rest of the country doesn't: state license verification. Here's the full checklist, Texas-specific.
Step 1: Decide what you actually need in Texas
Before you call anyone in Texas, get clear on which of these you need:
- Spot-check inspection -- 'I see something on this wall.' Single area, usually no samples.
- Whole-home assessment -- 'Does this house have a mould problem?'
- Documentation inspection -- written report for insurance / real estate / a dispute.
- Post-remediation verification -- confirming cleanup succeeded.
- Pre-purchase inspection -- often bundled with a home inspection.
Different scopes have different prices and require different tools. An inspector who pushes you into a bigger scope before understanding what you actually need is a yellow flag regardless of what state you're in.
Step 2: Verify the Texas state license
Texas requires mold assessors to hold a state licence through the Texas Department of Licensing and Regulation (TDLR). This is non-negotiable for any report you'll use for insurance, real estate, or legal purposes.
- Ask the inspector for their Texas licence number before scheduling.
- Visit https://www.tdlr.texas.gov/mlds/mlds.htm and verify the number directly.
- Confirm the licence is ACTIVE and matches the class of work being quoted.
- Look for open disciplinary actions.
An unlicensed Texas mold inspection isn't admissible for insurance claims, real-estate transactions, or legal proceedings. The $100-$300 pricing premium for a licensed pro is cheap insurance.
Step 3: Check industry certifications on top of the licence
A Texas licence is the baseline. On top of that, look for industry-respected certifications:
- ACAC CMI (Council-certified Microbial Investigator)
- ACAC CMC (Council-certified Microbial Consultant)
- IICRC AMRT / AMRS (Applied Microbial Remediation Technician/Supervisor)
- InterNACHI CMI (for home-inspection-adjacent work)
These are third-party credentials verifiable at the issuer's public registry. An experienced pro will typically hold at least one in addition to the state licence.
Step 4: Ask the conflict-of-interest question
Regardless of state, this is the single most important question to ask before hiring:
Do you also do remediation work? If so, are you willing to provide just the inspection report so I can shop the remediation quote separately?
The honest answer is yes to both. The unhealthy answer is 'we only do these together' or 'our remediation pricing is contingent on us doing the inspection.'
New York law explicitly bars the same firm from doing both assessment and remediation on the same job. Even though this isn't required in Texas, it's considered best practice industry-wide. Prefer an inspector who is independent of the remediator.
Step 5: Get a written scope BEFORE booking
A reputable inspector anywhere will provide a written scope-of-work (or detailed quote) describing:
- Areas to be inspected
- Tools used (visual, moisture meter, thermal camera, sample types)
- Number and type of samples (if any), with per-sample cost
- Lab used for analysis (if applicable)
- Deliverable format and timing
- Total quoted price including taxes and fees
Push-back on putting the scope in writing is a red flag. There's no legitimate reason to keep it verbal.
Step 6: Trust the consultative tone
Beyond technical vetting, pay attention to how the inspector talks. A qualified Texas pro will:
- Ask about your home's history (water events, prior remediation, occupant symptoms) BEFORE quoting
- Explain WHY they recommend a particular sample plan rather than just adding samples
- Be willing to say 'you don't need testing here' when that's the right answer
- Acknowledge limits -- e.g., 'I can't tell you what's behind that wall without opening it'
- Send a report you can share with anyone (no NDAs, no 'private' findings)
If it feels like a sales pitch, it is. Get a second opinion.
