Christian Alexander Castellanos

What this record tells you

Christian Alexander Castellanos holds Florida licence MRSA3791, a MRSA classification which authorises work as a licensed mold assessor. 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 2021, which makes it a relatively recent licence for the trade in this area. Roughly 51% of the 398 active mold inspection licences based in the Miami area were issued earlier than this one, and the local median sits at 2020. That is 5 years of continuous licensure.

Christian Alexander Castellanos is one of 240 active mold inspection licences registered to an address in Miami, so you have local alternatives to compare quotes against. Christian Alexander Castellanos 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.
