The Texas Department of Licensing and Regulation (TDLR) oversees mold remediation in Texas through the Mold Assessors and Remediators Occupations Code and Administrative Rules.
Residential property owners are exempt from licensing if they choose to perform mold cleanup themselves. However, the statute applies when anyone is hired to perform remediation.
- If the total affected area is less than 25 contiguous square feet, the property owner may hire any contractor to do the work.
- If the affected area is 25 contiguous square feet or more, remediation must be performed by a licensed Mold Remediation Contractor (MRC).
Non-residential properties follow a similar rule: owners, tenants, or their agents are not required to be licensed unless the affected area is 25 contiguous square feet or more. Beyond that threshold, a licensed MRC must perform the remediation.
In addition, whenever remediation is performed by a licensed MRC – regardless of project size – Texas law requires that a licensed Mold Assessment Consultant (MAC) first conduct an inspection and issue a written remediation protocol (work plan). This is a service NTX Enviro provides.
Why Use a Licensed Contractor?
Hiring a licensed MRC ensures the project is completed with the proper experience, equipment, and procedures, reducing the risk of cross-contamination or incomplete cleanup. It also makes your project eligible for a Certificate of Mold Damage Remediation (CMDR), a document issued by the Texas Department of Insurance.
A CMDR is available when remediation is performed by a licensed MRC following a written protocol and passes a Post Remediation Clearance Inspection conducted by a licensed MAC, such as NTX Enviro. The certificate provides proof that remediation was completed professionally and that the cause of mold was addressed.
Consumer Protection
As part of the process, Texas law requires that consumers receive the Consumer Mold Information Sheet (CMIS). This document explains your rights and outlines mold regulation in Texas. A copy must be provided to both the client and property owner (if different).
The CMIS is available on the TDLR website here: Consumer Mold Information Sheet (PDF).
