Christopher Costantino

What this record tells you

Christopher Costantino holds Florida licence MRSR1831, 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 2011, which makes it a long-held licence for the trade in this area. Roughly 6% of the 96 active mold remediation licences based in the Port St. Lucie & Treasure Coast area were issued earlier than this one, and the local median sits at 2019. That is 15 years of continuous licensure.

Christopher Costantino is one of 14 active mold remediation licences registered to an address in Stuart, so you have local alternatives to compare quotes against. Christopher Costantino 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.
