Mcmillen & Sons Construction, Inc.

What this record tells you

Mcmillen & Sons Construction, Inc. holds Florida licence CBC1261704, a CBC classification which authorises work as a certified/registered building or residential contractor. A "C" prefix means the licence is certified — valid anywhere in Florida.

This licence was first issued in 2017, which makes it an established licence for the trade in this area. Roughly 49% of the 213 active home building & remodeling licences based in the Key West & The Keys area were issued earlier than this one, and the local median sits at 2017. That is 9 years of continuous licensure.

Mcmillen & Sons Construction, Inc. is one of 34 active home building & remodeling licences registered to an address in Marathon, so you have local alternatives to compare quotes against.

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.
