What this record tells you

Tcb Envirocorp Inc holds Florida licence CGC1519836, 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 2011, which makes it a long-held licence for the trade in this area. Roughly 55% of the 1,400 active general contracting licences based in the Jacksonville area were issued earlier than this one, and the local median sits at 2008. That is 15 years of continuous licensure.

Tcb Envirocorp Inc is one of 102 active general contracting licences registered to an address in Saint Augustine, so you have local alternatives to compare quotes against. Mark Stephen Mongon additionally holds 2 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 08/31/2026. 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.
