Kolsen and Associates LLC

What this record tells you

Kolsen and Associates LLC holds Florida licence RG0066765, a RG classification which authorises work as a certified/registered general contractor. An "R" prefix means the licence is registered, which limits work to the local jurisdictions that accepted it rather than the whole state.

This licence was first issued in 1999, which makes it one of the longest-held licences for the trade in this area. Roughly 19% of the 1,400 active general contracting licences based in the Jacksonville area were issued earlier than this one, and the local median sits at 2008. That is 27 years of continuous licensure.

Kolsen and Associates LLC is one of 102 active general contracting licences registered to an address in Saint Augustine, so you have local alternatives to compare quotes against. William J Kolsen 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 08/31/2027. 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.
