David Mayes

What this record tells you

David Mayes holds Florida licence MRSR3074, a MRSR classification which authorises work as a licensed mold remediator. An "R" prefix means the licence is registered, which limits work to the local jurisdictions that accepted it rather than the whole state.

This licence was first issued in 2018, which makes it an established licence for the trade in this area. Roughly 50% of the 118 active mold remediation licences based in the Jacksonville area were issued earlier than this one, and the local median sits at 2018. That is 8 years of continuous licensure.

David Mayes is one of 64 active mold remediation licences registered to an address in Jacksonville, so you have local alternatives to compare quotes against. David Mayes additionally holds 1 other active Florida licence in our records, which can indicate a contractor qualified across more than one trade or entity.

The licence is recorded as expiring on 07/31/2028. Florida licences renew on a fixed cycle, and a licence that is not renewed moves to delinquent status — which is why the expiry date matters if you are planning work close to that date. Confirm the current status on the state portal before signing a contract.
