Greystone Construction Management, Inc.

What this record tells you

Greystone Construction Management, Inc. holds Florida licence CGC1531418, 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 2021, which makes it a relatively recent licence for the trade in this area. Roughly 76% of the 1,400 active general contracting licences based in the Jacksonville area were issued earlier than this one, and the local median sits at 2008. That is 5 years of continuous licensure.

Greystone Construction Management, Inc. is one of 735 active general contracting licences registered to an address in Jacksonville, so you have local alternatives to compare quotes against. Kenneth Jeff Martin 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 08/31/2026. 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.
