What this record tells you

Gm Painting & Construction holds Florida licence CGC1537128, 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 84% of the 2,706 active general contracting licences based in the West Palm Beach area were issued earlier than this one, and the local median sits at 2011. That is 2 years of continuous licensure.

Gm Painting & Construction is one of 40 active general contracting licences registered to an address in Lantana, so you have local alternatives to compare quotes against. William Mark Gannon 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 08/31/2026. 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.
