Advon Corporation

What this record tells you

Advon Corporation holds Florida licence CGC026737, 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 1983, which makes it one of the longest-held licences for the trade in this area. Roughly 5% of the 330 active general contracting licences based in the Tallahassee area were issued earlier than this one, and the local median sits at 2010. That is 43 years of continuous licensure.

Advon Corporation is one of 239 active general contracting licences registered to an address in Tallahassee, so you have local alternatives to compare quotes against.

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.
