Maintenance Masters LLC

What this record tells you

Maintenance Masters LLC holds Florida licence CBC054072, 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 1991, which makes it one of the longest-held licences for the trade in this area. Roughly 9% of the 1,681 active home building & remodeling licences based in the Jacksonville area were issued earlier than this one, and the local median sits at 2012. That is 35 years of continuous licensure.

Maintenance Masters LLC is one of 768 active home building & remodeling licences registered to an address in Jacksonville, so you have local alternatives to compare quotes against. Alvin Ernest Jr Knoepfel 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.
