Siska Plumbing LLC

What this record tells you

Siska Plumbing LLC holds Florida licence CFC1433514, 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 2025, which makes it one of the newer licences for the trade in this area. Roughly 84% 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 1 year of continuous licensure.

Siska Plumbing LLC is one of 84 active plumbing licences registered to an address in St Petersburg, 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.
