J & M Materials of Riverview, Inc.

What this record tells you

J & M Materials of Riverview, Inc. holds Florida licence CGC1540659, 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 2026, which makes it one of the newer licences for the trade in this area. Roughly 95% 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 0 years of continuous licensure.

J & M Materials of Riverview, Inc. is one of 80 active general contracting licences registered to an address in Plant City, so you have local alternatives to compare quotes against. Billy J Brock additionally holds 3 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.
