John Arthur Dietz

What this record tells you

John Arthur Dietz holds Florida licence MRSR2434, a MRSR classification which authorises work as a licensed mold remediator. 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 2013, which makes it a long-held licence for the trade in this area. Roughly 32% of the 249 active mold remediation licences based in the West Palm Beach area were issued earlier than this one, and the local median sits at 2019. That is 13 years of continuous licensure.

John Arthur Dietz is one of 5 active mold remediation licences registered to an address in Royal Palm Beach, so you have local alternatives to compare quotes against.

The licence is recorded as expiring on 07/31/2028. 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.
