Master Mechanical Services Inc holds Florida licence CFC1426279, a CFC classification which authorises work as a certified/registered plumbing contractor. A "C" prefix means the licence is certified — valid anywhere in Florida.
This licence was first issued in 2004, which makes it a long-held licence for the trade in this area. Roughly 10% of the 1,098 active plumbing licences based in the Miami area were issued earlier than this one, and the local median sits at 2022. That is 22 years of continuous licensure.
Master Mechanical Services Inc is one of 692 active plumbing licences registered to an address in Miami, so you have local alternatives to compare quotes against. William Shawn Flowers additionally holds 1 other active Florida licence 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.
