Guenther Construction Inc

What this record tells you

Guenther Construction Inc holds Florida licence CGC028631, 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 1984, which makes it one of the longest-held licences for the trade in this area. Roughly 7% of the 230 active general contracting licences based in the Key West & The Keys area were issued earlier than this one, and the local median sits at 2012. That is 42 years of continuous licensure.

Guenther Construction Inc is one of 50 active general contracting licences registered to an address in Tavernier, so you have local alternatives to compare quotes against. Robert Daniel Guenther 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.
