Duncan Plumbing Inc

What this record tells you

Duncan Plumbing Inc holds Florida licence CFC046010, 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 1988, which makes it one of the longest-held licences for the trade in this area. Roughly 6% of the 461 active plumbing licences based in the Jacksonville area were issued earlier than this one, and the local median sits at 2014. That is 38 years of continuous licensure.

Duncan Plumbing Inc is one of 23 active plumbing licences registered to an address in Orange Park, so you have local alternatives to compare quotes against.

The licence is recorded as expiring on 08/31/2026. 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.
