What this record tells you

Simpson Environmental Services, LLC holds Florida licence CGC1524454, 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 2016, which makes it an established licence for the trade in this area. Roughly 54% of the 1,770 active general contracting licences based in the Tampa area were issued earlier than this one, and the local median sits at 2013. That is 10 years of continuous licensure.

Simpson Environmental Services, LLC is one of 13 active general contracting licences registered to an address in San Antonio, so you have local alternatives to compare quotes against. Casey Franklin Mattox 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 08/31/2028. 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.
