Deangelis Diamond Construction, LLC

What this record tells you

Deangelis Diamond Construction, LLC holds Florida licence CGC037335, 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 1986, which makes it one of the longest-held licences for the trade in this area. Roughly 4% of the 1,000 active general contracting licences based in the Naples area were issued earlier than this one, and the local median sits at 2015. That is 40 years of continuous licensure.

Deangelis Diamond Construction, LLC is one of 937 active general contracting licences registered to an address in Naples, so you have local alternatives to compare quotes against. David B Diamond 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.
