Mainstream Construction Corp

What this record tells you

Mainstream Construction Corp holds Florida licence CCC1327706, a CCC classification which authorises work as a certified/registered roofing contractor. A "C" prefix means the licence is certified — valid anywhere in Florida.

This licence was first issued in 2006, which makes it a long-held licence for the trade in this area. Roughly 30% of the 37 active roofing licences based in the Key West & The Keys area were issued earlier than this one, and the local median sits at 2011. That is 20 years of continuous licensure.

Mainstream Construction Corp is one of 6 active roofing licences registered to an address in Tavernier, so you have local alternatives to compare quotes against. Sergio Rubio 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.
