What this record tells you

Ralph William Dumke holds Florida licence CGC1522018, 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 2014, which makes it an established licence for the trade in this area. Roughly 61% 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 12 years of continuous licensure.

Ralph William Dumke is one of 28 active general contracting licences registered to an address in Ponte Vedra, so you have local alternatives to compare quotes against. Ralph William Dumke 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 08/31/2028. 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.
