Mark Allen Knowles

What this record tells you

Mark Allen Knowles holds Florida licence CRC057681, a CRC 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 1999, which makes it one of the longest-held licences for the trade in this area. Roughly 16% 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 27 years of continuous licensure.

Mark Allen Knowles is one of 768 active home building & remodeling licences registered to an address in Jacksonville, 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.
