Keller Marine Construction LLC

What this record tells you

Keller Marine Construction LLC holds Florida licence CGC1536549, a CGC classification which authorises work as a certified/registered general contractor. A "C" prefix means the licence is certified — valid anywhere in Florida.

This licence was first issued in 2024, which makes it one of the newer licences for the trade in this area. Roughly 79% of the 309 active general contracting licences based in the Port Charlotte & Punta Gorda area were issued earlier than this one, and the local median sits at 2016. That is 2 years of continuous licensure.

Keller Marine Construction LLC is one of 22 active general contracting licences registered to an address in Arcadia, 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.
