What this record tells you

This licence was first issued in 1986, which makes it one of the longest-held licences for the trade in this area. Roughly 7% of the 272 active general contracting licences based in the Spring Hill & Nature Coast area were issued earlier than this one, and the local median sits at 2010. That is 40 years of continuous licensure.

O'Donnell Impact Windows & Storm Protection is one of 36 active general contracting licences registered to an address in Crystal River, so you have local alternatives to compare quotes against. William H III Miller 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.
