Gruenthal Construction and Development Corp

What this record tells you

Gruenthal Construction and Development Corp holds Florida licence CGC022748, 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 1982, which makes it one of the longest-held licences for the trade in this area. Roughly 4% of the 2,706 active general contracting licences based in the West Palm Beach area were issued earlier than this one, and the local median sits at 2011. That is 44 years of continuous licensure.

Gruenthal Construction and Development Corp is one of 124 active general contracting licences registered to an address in Wellington, so you have local alternatives to compare quotes against. Robert Gruenthal 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 08/31/2026. 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.
