Cannon Plumbing Services LLC

What this record tells you

Cannon Plumbing Services LLC holds Florida licence CFC1431744, 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 2022, which makes it a relatively recent licence for the trade in this area. Roughly 69% 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 4 years of continuous licensure.

Cannon Plumbing Services LLC is one of 259 active plumbing licences registered to an address in Jacksonville, so you have local alternatives to compare quotes against. Olin Marshall Cannon 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 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.
