Black Diamond Excavating LLC

What this record tells you

Black Diamond Excavating LLC holds Florida licence CBC010965, a CBC classification which authorises work as a certified/registered building or residential contractor. A "C" prefix means the licence is certified — valid anywhere in Florida.

This licence was first issued in 1977, which makes it one of the longest-held licences for the trade in this area. Roughly 0% of the 470 active home building & remodeling licences based in the Gainesville area were issued earlier than this one, and the local median sits at 2009. That is 49 years of continuous licensure.

Black Diamond Excavating LLC is one of 26 active home building & remodeling licences registered to an address in Keystone Heights, so you have local alternatives to compare quotes against.

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.
