Carlos Alvarez

What this record tells you

Carlos Alvarez holds Florida licence MRSR5717, 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 2026, which makes it one of the newer licences for the trade in this area. That is 0 years of continuous licensure.

Carlos Alvarez is one of 2 active mold remediation licences registered to an address in Marathon, so you have local alternatives to compare quotes against. Carlos Alvarez additionally holds 3 other active Florida licences 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.
