Texas Rules On Mold

Who May Do Mold Work

Texas licenses mold assessment consultants, assessment technicians, remediation contractors, remediation workers and the companies they work for through the Texas Department of Licensing and Regulation. A license is needed when the mold covers 25 contiguous square feet or more.

State law says a license holder may not do both the mold assessment and the mold remediation on the same project. A person also may not own a share of both the assessment company and the remediation company on the same project. You can check any license with the TDLR license search.
