M&m Master Construction LLC

What this record tells you

M&m Master Construction LLC holds Florida licence CFC1434675, 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 2026, which makes it one of the newer licences for the trade in this area. Roughly 90% 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 0 years of continuous licensure.

M&m Master Construction LLC is one of 692 active plumbing licences registered to an address in Miami, so you have local alternatives to compare quotes against. Manuel Miralles Sosa 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.
