What this record tells you

Keys Contracting Services Inc holds Florida licence CGC1521156, 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 2012, which makes it a long-held licence for the trade in this area. Roughly 49% of the 230 active general contracting licences based in the Key West & The Keys area were issued earlier than this one, and the local median sits at 2012. That is 14 years of continuous licensure.

Keys Contracting Services Inc is one of 33 active general contracting licences registered to an address in Marathon, so you have local alternatives to compare quotes against. John Christopher Gratton 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.
