What this record tells you

Underground Plumbing LLC holds Florida licence CFC1432722, 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 2024, which makes it one of the newer licences for the trade in this area. Roughly 80% of the 315 active plumbing licences based in the Port St. Lucie & Treasure Coast area were issued earlier than this one, and the local median sits at 2016. That is 2 years of continuous licensure.

Underground Plumbing LLC is one of 32 active plumbing licences registered to an address in Stuart, so you have local alternatives to compare quotes against. Christopher M Sequeira additionally holds 2 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.
