This licence was first issued in 2019, which makes it an established licence for the trade in this area. Roughly 63% 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.

William Joseph Mazar additionally holds 3 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 08/31/2026. 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.
