FUNK, WILLIAM
Winter Haven, FL
What does this license mean?
MRSR is the Florida state mold remediation license — required to do the actual removal on any job larger than about 10 square feet. MRSA is the separate assessor (testing) license. State law keeps the two roles independent so the company that finds the mold isn't the one that profits from removing it.

A note on Florida law
In Florida, the company that assesses (tests) the mold on a property generally can't be the same company that remediates it within 12 months. This firm is licensed for both, so on any given job it can do one role — not both on the same property. Ask which role they'd be filling for you, and who would handle the independent clearance test.
