Winston Dario Castaneda

What this record tells you

Winston Dario Castaneda holds Florida licence MRSR4469, 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 2022, which makes it a relatively recent licence for the trade in this area. Roughly 64% of the 351 active mold remediation licences based in the Miami area were issued earlier than this one, and the local median sits at 2020. That is 4 years of continuous licensure.

Winston Dario Castaneda is one of 232 active mold remediation licences registered to an address in Miami, so you have local alternatives to compare quotes against. Winston Dario Castaneda 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.
