Greystone Construction Management, Inc.

What this record tells you

Greystone Construction Management, Inc. holds Florida licence RF11067940, a RF classification which authorises work as a certified/registered plumbing 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 2023, which makes it a relatively recent licence for the trade in this area. Roughly 74% of the 461 active plumbing licences based in the Jacksonville area were issued earlier than this one, and the local median sits at 2014. That is 3 years of continuous licensure.

Greystone Construction Management, Inc. is one of 259 active plumbing licences registered to an address in Jacksonville, so you have local alternatives to compare quotes against. Kenneth Jeff Martin additionally holds 2 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 08/31/2027. 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.
