Osvaldo Jr Calzada

What this record tells you

Osvaldo Jr Calzada holds Florida licence MRSR110, 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 2010, which makes it a long-held licence for the trade in this area. Roughly 0% of the 351 active mold remediation licences based in the Miami area were issued earlier than this one, and the local median sits at 2020. That is 16 years of continuous licensure.

Osvaldo Jr Calzada is one of 7 active mold remediation licences registered to an address in Coral Gables, so you have local alternatives to compare quotes against. Osvaldo Jr Calzada 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 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.
