Double D'S Plumbing Expertise LLC

What this record tells you

Double D'S Plumbing Expertise LLC holds Florida licence RF11068016, a RF classification which authorises work as a certified/registered plumbing contractor. 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 2025, which makes it one of the newer licences for the trade in this area. Roughly 87% 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 1 year of continuous licensure.

Double D'S Plumbing Expertise LLC is one of 30 active plumbing licences registered to an address in Port Saint Lucie, so you have local alternatives to compare quotes against.

The licence is recorded as expiring on 08/31/2027. 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.
