Impact Design Build LLC holds Florida licence CGC057251, 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 1993, which makes it one of the longest-held licences for the trade in this area. Roughly 13% 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 33 years of continuous licensure.
Impact Design Build LLC is one of 86 active general contracting licences registered to an address in St Augustine, so you have local alternatives to compare quotes against.
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.
