Interested in a license to become a Texas Mold Assessment Technician, Mold Assessment Consultant, Mold Remediation Contractor or Mold Worker? 

Mold remediation in the state of Texas is governed by the Mold Program division of the Texas Department of State Health Services and the Texas Mold Assessment and Remediation Rules (TMARR). 

The Texas Mold Regulations are an attempt to regulate and professionalize the mold remediation and assessment industry through a series of licensing requirements, minimum performance standards, documentation requirements, and penalties.

All persons performing mold assessments and mold remediation in Texas, if not exempt under the Texas Mold Assessment and Remediation Rules, are required to be licensed or registered.  This includes mold assessment companies, mold analysis laboratories, mold assessment technicians, mold assessment consultants, mold remediation workers (with registration as a worker), mold remediation contractors, and mold remediation companies.

Individuals who inspect, analyze and recommend remediation actions are known as mold assessors. Individuals who engage in the business of correcting mold problems are known as mold remediators. To do either, Texas law requires a license from the Texas Department of State Health Services (TDSHS).
