J L M Mechanical LLC

What this record tells you

J L M Mechanical LLC holds Florida licence CFC1427986, a CFC classification which authorises work as a certified/registered plumbing contractor. A "C" prefix means the licence is certified — valid anywhere in Florida.

This licence was first issued in 2009, which makes it a long-held licence for the trade in this area. Roughly 33% of the 562 active plumbing licences based in the West Palm Beach area were issued earlier than this one, and the local median sits at 2017. That is 17 years of continuous licensure.

J L M Mechanical LLC is one of 114 active plumbing licences registered to an address in West Palm Beach, so you have local alternatives to compare quotes against. Jeffery Lee Mcconaha 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 08/31/2026. 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.
