1nsg, Corp.

What this record tells you

1nsg, Corp. holds Florida licence CGC1536356, a CGC classification which authorises work as a certified/registered general contractor. A "C" prefix means the licence is certified — valid anywhere in Florida.

This licence was first issued in 2024, which makes it one of the newer licences for the trade in this area. Roughly 78% of the 5,272 active general contracting licences based in the Miami area were issued earlier than this one, and the local median sits at 2016. That is 2 years of continuous licensure.

1nsg, Corp. is one of 3,292 active general contracting licences registered to an address in Miami, so you have local alternatives to compare quotes against. Juan A Serrat additionally holds 1 other active Florida licence in our records, which can indicate a contractor qualified across more than one trade or entity.

The licence is recorded as expiring on 08/31/2026. 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.
