Long Hai Nguyen

What this record tells you

Long Hai Nguyen holds Florida licence MRSA4239, 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 2022, which makes it a relatively recent licence for the trade in this area. Roughly 54% of the 273 active mold inspection licences based in the Orlando area were issued earlier than this one, and the local median sits at 2021. That is 4 years of continuous licensure.

Long Hai Nguyen is one of 16 active mold inspection licences registered to an address in Winter Garden, 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.
