What this record tells you

Intron Technologies Inc holds Florida licence CBC059663, 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 2000, which makes it one of the longest-held licences for the trade in this area. Roughly 17% 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 26 years of continuous licensure.

Intron Technologies Inc is one of 768 active home building & remodeling licences registered to an address in Jacksonville, so you have local alternatives to compare quotes against. Douglas Dryden Windsor 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.
