Mark Warren Jr Theisen

What this record tells you

Mark Warren Jr Theisen holds Florida licence CGC1518450, 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 2010, which makes it a long-held licence for the trade in this area. Roughly 43% of the 2,352 active general contracting licences based in the Orlando area were issued earlier than this one, and the local median sits at 2013. That is 16 years of continuous licensure.

Mark Warren Jr Theisen is one of 158 active general contracting licences registered to an address in Winter Park, so you have local alternatives to compare quotes against.

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.
