TDLR Mold License Lookup: How to Check a Texas Mold Company
Before you compare prices from mold companies in Corpus Christi, TX, check their licenses. Texas licenses mold work at the state level, the records are public, and the check takes a few minutes. This guide explains which license each role should hold, how to run the lookup, and what the result can and cannot tell you.
The short version. Texas requires TDLR licenses for mold assessment and remediation work on 25 or more contiguous square feet (Occ. Code §1958.101–.102). Verify any company at tdlr.texas.gov/LicenseSearch. TDLR's mold program page links to the same search as "Verify a License."
Do mold companies need a license in Texas?
Yes, for regulated work. Occupations Code §1958.101(a) says "a person may not engage in: (1) mold assessment unless the person holds a mold assessment license; or (2) mold remediation unless the person holds a mold remediation license." Licenses are "valid for two years" (§1958.1011), so a license that was current when a company printed its truck signs may not be current now.
The main exemption is size. Work on less than 25 contiguous square feet can generally be done by people who are not licensed, and owners and tenants have some exemptions on their own property (see Texas mold rules and the 25 square foot line). But TDLR's FAQ says "a licensed MRC performing a small mold remediation project (less than 25 contiguous square feet) is not exempt from the law and rules." If a company says it is licensed, the license rules apply to its work whatever the size.
TDLR's At a Glance sheet reports 5,646 mold licensees statewide in fiscal year 2025, so a real license record is easy to find for most active companies.
Which TDLR mold license should the company have?
TDLR issues separate licenses for the assessment side and the remediation side. The company you hire for each role should hold a license on that side. Fees below are from TDLR's At a Glance sheet (FY 2025) and are shown only to help you recognize the license types.
| License type | Side | TDLR fee |
|---|---|---|
| Mold Assessment Technician | Assessment | $150 |
| Mold Assessment Consultant | Assessment (writes the protocol, performs clearance) | $500 |
| Mold Assessment Company | Assessment | $850 |
| Mold Remediation Worker Registration | Remediation | $50 |
| Mold Remediation Contractor | Remediation (writes the work plan, issues the CMDR) | $450 |
| Mold Remediation Company | Remediation | $850 |
| Mold Analysis Laboratory | Analyzes samples | $750 |
| Mold Training Provider Accreditation | Training courses | Not listed here |
On a job of 25 contiguous square feet or more, expect a licensed consultant on the assessment side and a licensed contractor on the remediation side. TDLR's FAQ is direct about the certificate at the end: "Only a licensed remediator is authorized to give a CMDR."
How do I look up a TDLR mold license?
Get the details in writing
Ask each company for its TDLR license number and the exact business name on the license. If an individual consultant or contractor will be responsible for your job, ask for that person's name and number too.
Open the TDLR search
Go to tdlr.texas.gov/LicenseSearch. You can also reach it from TDLR's mold program page through the "Verify a License" link.
Search the record
Search using the license number or the name the company gave you. The search form's fields and menus can change, so follow the on-screen prompts and choose the mold program or license type if the page asks.
Read what comes back
Check that the license type matches the role (assessment or remediation), that the license is current rather than expired, and that the name matches the one on your quote or contract.
Repeat for the other company
Look up both the assessor and the remediator. They should be two different companies, because Texas does not allow one company or one owner on both sides of the same project.
Save a copy
Take a screenshot or print the result with the date. Keep it with the protocol, work plan and certificate.
Can the mold inspector also do the removal?
Not on the same job. In Texas, the company that assesses your mold and writes the protocol cannot be the company that removes it on the same project, and one owner can't hold both (Occ. Code §1958.155). TDLR's FAQ says "you are not allowed to conduct both mold assessment and mold remediation activities on the same project." A license lookup shows you each company's license, but it may not show who owns what. If two companies seem connected, ask each one directly whether they share an owner.
What a license lookup can't tell you
A valid license means the company or person is authorized for that type of work. It does not rate quality, confirm the price is fair, or show every business relationship. To round out the picture:
- Ask for the Consumer Mold Information Sheet (CMIS). TDLR publishes it, and licensees are expected to give it to clients before work begins.
- Get the remediation protocol and the work plan in writing before work starts.
- Ask whether TDLR notification will be filed and when (on 25+ square foot jobs).
- Ask who will perform the clearance assessment, and confirm you will receive the before-and-after photos and the Certificate of Mold Damage Remediation.
- If something goes wrong, TDLR takes complaints at tdlr.texas.gov/complaints or by phone at (512) 463-6599 or (800) 803-9202.
Red flags when hiring a mold company
General advice, not a legal checklist:
- Offers to both test and remove the mold on your project.
- Will not give a license number, or the number does not match the name on the quote.
- Will not put the protocol or work plan in writing.
- Wants full payment upfront.
- Insists the species must be identified before anything can happen. TDLR's FAQ says "Generally, it is not necessary to identify the species of mold growing in a residence."
- Tells you "Texas doesn't license mold companies." It does, through TDLR.
- Knocks on doors after a storm and pushes you to sign that day. Texas Business and Commerce Code chapter 601 generally lets a consumer cancel an in-home sale over $25 until midnight of the third business day after signing. Whether it applies depends on the transaction, so read the contract's cancellation notice.
Once both licenses check out, compare quotes on scope, containment, what is removed versus cleaned, and what rebuild work is excluded. The mold remediation cost guide for Corpus Christi shows published national ranges, and the how it works page lays out the steps. For what each side of the job involves, see mold inspection and testing and mold removal and remediation; for storm-related jobs, see hurricane and flood mold.
Frequently asked questions
How do I check if a mold company is licensed in Texas?
Ask for the company's TDLR license number and business name, then look it up at tdlr.texas.gov/LicenseSearch. Confirm the license type matches the role (assessment or remediation), that it is current, and that the name matches your quote. Do the same for the second company on the job.
Can one company inspect and remove mold in Texas?
Not on the same project. Occupations Code §1958.155 says a license holder may not perform both mold assessment and mold remediation on the same project, and one person may not own an interest in both companies on that project.
Does a mold company need a license for a small job?
Unlicensed people can generally do mold work on less than 25 contiguous square feet. But TDLR says a licensed remediation contractor doing a small project is still bound by the law and rules, so a licensed company should follow them on any size job.
Where do I file a complaint about a Texas mold company?
TDLR handles complaints about mold licensees and unlicensed mold work. Use tdlr.texas.gov/complaints or call (512) 463-6599 or (800) 803-9202.
