Leszek Grzanka

What this record tells you

Leszek Grzanka holds Florida licence MRSR3658, 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 2020, which makes it an established licence for the trade in this area. Roughly 54% 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 6 years of continuous licensure.

Leszek Grzanka is one of 23 active mold remediation licences registered to an address in Lake Worth, so you have local alternatives to compare quotes against. Leszek Grzanka additionally holds 3 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 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.
