Gulfstream Building Corporation holds Florida licence CBC010709, 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 1976, which makes it one of the longest-held licences for the trade in this area. Roughly 0% of the 1,203 active home building & remodeling licences based in the West Palm Beach area were issued earlier than this one, and the local median sits at 2017. That is 50 years of continuous licensure.
Gulfstream Building Corporation is one of 64 active home building & remodeling licences registered to an address in Delray Beach, so you have local alternatives to compare quotes against. Robert J Mcdonald additionally holds 3 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 08/31/2028. 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.
