What this record tells you

Global Building Corp holds Florida licence CGC062053, 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 2001, which makes it one of the longest-held licences for the trade in this area. Roughly 27% of the 1,090 active general contracting licences based in the Port St. Lucie & Treasure Coast area were issued earlier than this one, and the local median sits at 2008. That is 25 years of continuous licensure.

Global Building Corp is one of 34 active general contracting licences registered to an address in Sebastian, so you have local alternatives to compare quotes against. William Allen Kirby 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 08/31/2028. 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.
