William Paul Spilker

What this record tells you

William Paul Spilker holds Florida licence MRSR1642, 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 2011, which makes it a long-held licence for the trade in this area. Roughly 6% of the 118 active mold remediation licences based in the Jacksonville area were issued earlier than this one, and the local median sits at 2018. That is 15 years of continuous licensure.

William Paul Spilker is one of 64 active mold remediation licences registered to an address in Jacksonville, 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.
