Short answer
In Texas, mold remediation for hire is done by companies licensed by TDLR as Mold Remediation Companies. Compare quotes against the same written plan (the remediation protocol from a separately licensed assessor, where one is required), make sure the moisture source is dealt with, and check each company's license in the TDLR search before you sign.
Start from the assessment and the protocol
Texas licenses mold assessment and mold remediation separately. The assessor inspects the property and, where needed, writes the remediation protocol: which areas and materials are affected and how the work should be done. Share the same protocol with every remediation company you ask for a quote, so each price covers the same work. If a quote departs from the protocol, ask why in writing.
One project, two separate firms
TDLR's guidance says a licensee may not conduct both the mold assessment and the mold remediation on the same project. A company can hold both licenses, but on your job one firm does the assessment and a different firm does the remediation. If a remediation company offers to test the property as well, ask which licensed assessment firm will do that part.
Ask about the moisture source
The EPA's homeowner guide puts it simply: the key to mold control is moisture control. Ask each company whether the leak, drainage or humidity problem behind the mold is part of its scope, or whether you need a plumber, roofer or HVAC contractor first. Get it in writing who repairs what, and in which order.
Containment, removal and rebuild
Ask how the work area will be separated from the rest of the property, which materials will be removed and which cleaned, how waste leaves the building, and whether drywall, flooring or other finishes are put back afterwards or left for another contractor. Rebuild work is often quoted separately.
Clearance and the Certificate of Mold Damage Remediation
TDLR's FAQ explains that a licensed assessment consultant determines clearance after a post-remediation assessment, and that only a licensed remediator may issue a Certificate of Mold Damage Remediation (CMDR), which it must give to the property owner. Ask who arranges the post-remediation assessment and keep the certificate with your records.
If an insurance claim is involved
Ask your insurer what it needs before work starts, and keep copies of the assessment, the protocol, photos, invoices and the certificate. We don't advise on coverage; your policy and your insurer decide that.

Frequently asked questions
Can the company that tested my home also remove the mold?
+
TDLR's guidance says a licensee may not conduct both the mold assessment and the mold remediation on the same project. A company can hold both licenses, but on your job one firm does the assessment and a different firm does the remediation.
Do I need a licensed company for a small area?
+
TDLR's FAQ says areas of visible mold of less than 25 contiguous square feet can be cleaned up by people who are not licensed, and that homeowners can in some circumstances do their own remediation. Licensed companies must follow the rules even on small jobs. Read TDLR's FAQ for the conditions that apply.
How do I check a company's license?
