Mayor Plumbing Services

What this record tells you

Mayor Plumbing Services holds Florida licence CFC1433975, a CFC classification which authorises work as a certified/registered plumbing contractor. A "C" prefix means the licence is certified — valid anywhere in Florida.

This licence was first issued in 2025, which makes it one of the newer licences for the trade in this area. Roughly 77% of the 1,098 active plumbing licences based in the Miami area were issued earlier than this one, and the local median sits at 2022. That is 1 year of continuous licensure.

Mayor Plumbing Services is one of 12 active plumbing licences registered to an address in Aventura, so you have local alternatives to compare quotes against. Nelson Alexander Polanco additionally holds 4 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 08/31/2028. 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.
