Florida mold licenses and certifications, explained

In Florida, “licensed and certified” isn’t marketing — it’s two different, checkable things. A state license (Mold Remediator, MRSR, or Mold Assessor, MRSA) is required by law for any mold job over ten square feet, and the state keeps a public record of whether it’s active, expired, or disciplined. An IICRC certification (such as AMRT, Applied Microbial Remediation Technician) is an industry credential that says the people doing the work were trained to a recognized standard. Good companies carry both; the license is the one the state can revoke.

Florida also splits the job in two on purpose. The company that assesses your mold — tests it, scopes it, writes the protocol — generally can’t be the same company that remediates it on the same property within twelve months. That rule exists because the firm writing the estimate shouldn’t be the firm profiting from inflating it. When one company offers to both “test and fix” your mold, that’s the exact spot homeowners get overcharged.

These guides explain what each credential proves, how to read a license number, how to confirm it yourself on the state registry in about a minute, and why the assess-then-remediate split is a feature that protects you. Every contractor we list links straight to its source record, so a badge here is something you can check — not something you have to trust.
