Joe W. Mange Company LLC holds Florida licence CBC041875, 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 1987, which makes it one of the longest-held licences for the trade in this area. Roughly 6% of the 470 active home building & remodeling licences based in the Gainesville area were issued earlier than this one, and the local median sits at 2009. That is 39 years of continuous licensure.
Joe W. Mange Company LLC is one of 26 active home building & remodeling licences registered to an address in Keystone Heights, so you have local alternatives to compare quotes against. Joseph Woodruff Jr Mange additionally holds 4 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.
