"We had a great result using them. I originally called because of an issue in a room with a bay window - it was very cold in the window, as though they didn't insulate properly underneath. They offered to come in and do the energy audit. Their recommendations were reasonable, and included a fix for the bay window insulation issue. There was no "hard sell". Their estimated savings for implementing the improvements were $1700 / year. We had the option to finance and roll the costs into our PSEG LI bill, or pay up front (and get a small additional discount).
I've recommended them to others, who have had similar positive results.

"They showed up exactly when they said they would. They were efficient, neat and made sure to send me pictures in the various stages of execution. And they cleaned up better than when they found the area. I would highly recommend them. I wish he did more than insulation because he would be my go-to guy for all house related needs."
