Hiring mold remediation in Houston

Fix the water first. EPA says the key to mold control is moisture control, and recommends drying water-damaged areas and items within 24–48 hours. After a storm, flood or plumbing leak, document the damage with photos before cleanup.

TDLR says that in most cases visible mold of less than 25 contiguous square feet can be cleaned up by people who are not licensed. For larger jobs, hire a licensed assessment consultant to write a protocol, get 2–3 written remediation quotes against it, and ask for the Certificate of Mold Damage Remediation (TDI form MDR-1) when the job passes.

Frequently asked questions

How do I check that a Houston mold assessor or remediator is licensed?

Search the name or license number on TDLR License Search. Texas mold license numbers start with MAC (assessment consultant), MRC (remediation contractor), ACO (assessment company) or RCO (remediation company). Look for a current status and expiration date. See how to verify a Texas mold license.

What is the difference between mold assessment and mold remediation?

A licensed mold assessment consultant inspects, samples where useful and writes the remediation protocol. A licensed mold remediation contractor removes, cleans or treats the mold following that protocol. Texas law says one license holder may not do both on the same project. Read our assessment vs. remediation guide.

Do I need a licensed company for a small patch of mold?

Often not. TDLR says that in most cases visible mold of less than 25 contiguous square feet can be cleaned up by people who are not licensed. Larger areas generally need licensed assessment and remediation, with exemptions for some owners and small landlords. If you do hire a licensed remediator, they must follow the rules whatever the size.

Should I fix the leak before mold remediation?

Yes, the moisture source has to be fixed or the mold can return. EPA says you must clean up the mold and fix the water problem, and recommends drying water-damaged areas and items within 24–48 hours to prevent mold growth. See mold after water damage.

What paperwork should I get?

Before work starts, a licensed remediator should give you TDLR's Consumer Mold Information Sheet. You should get the assessor's written protocol, the remediator's work plan and contract, and, once the project passes, a Certificate of Mold Damage Remediation (TDI form MDR-1). Keep it: it matters for insurance and if you sell the home.
