What this record tells you

All Set Plumbing LLC holds Florida licence CFC1426963, 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 2006, which makes it a long-held licence for the trade in this area. Roughly 24% of the 435 active plumbing licences based in the St. Petersburg & Clearwater area were issued earlier than this one, and the local median sits at 2019. That is 20 years of continuous licensure.

All Set Plumbing LLC is one of 82 active plumbing licences registered to an address in Clearwater, so you have local alternatives to compare quotes against. Mark Williams 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 08/31/2026. 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.
