How the company started

October 2012. Sandy tears through the South Shore. Dan is working for someone else at the time, doing framing and insulation on new construction in Nassau County. After the storm, he drives through Long Beach, Island Park, Freeport. Every other house has insulation ripped off. Vinyl peeling like wet paper.

The FEMA money starts flowing. National companies roll in from out of state. They do not know Long Island. They do not know the building codes, the setbacks, the salt air. They do not know which inspector covers Hempstead versus Baldwin. They send crews that have never seen nor’easter wind loads.

Dan starts the company in January 2013 with two guys and a trailer. First jobs are Sandy rebuilds on the South Shore. The pitch is simple: local crew, local knowledge, we show up when we say we will. By 2014 the rebuilds turn into insulates. By 2017 it is word of mouth across most of Nassau. By 2023, the crew is twelve people and 680 homes done.

The company still runs the same way it did in 2013. Dan still does walk-throughs. Marco writes the quotes. Sarah handles the permits and scheduling. The installers are full-time employees, not day labor. And we handle the rebate paperwork — you just feel the difference.
