FIRMSTONE, NATALIE DAWN
ALVA, 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.
