Mold Assessors and Remediators: Licensing in TX and FL

Hire a licensed mold assessor to test and write the plan, and a separate licensed mold remediator to do the work. Texas licenses both through TDLR and bars one license holder from doing both on the same project. Florida licenses both through DBPR and bars an assessor's company from remediating a structure it assessed in the past 12 months, with limited exceptions.

In Texas, TDLR licenses mold assessors and remediators (Occupations Code 1958.101). In Florida, DBPR does under Chapter 468, Part XVI (Florida Statutes), and using titles like licensed mold assessor without a license is prohibited (468.8419).

Why two different companies?

Both states separate testing from fixing. Texas bars one license holder from doing both on the same project, and bars owning both firms on one project (1958.155). Florida bars an assessor's company from remediating a structure it assessed within 12 months, bars referral fees between them, and bars assessments whose fee depends on the findings (468.8419).

What paperwork should you get?

In Texas, the remediator must give you a certificate of mold remediation within 10 days, signed off by a licensed assessor, and you must give buyers copies of certificates from the past five years when you sell (1958.154).

When is no license needed?

Texas exempts owners and tenants working on their own property, except for 25 contiguous square feet or more, and anyone remediating less than 25 contiguous square feet (1958.102). Florida's law covers mold growth over 10 square feet and exempts residential owners working on their own property.
