"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.

"It was about 30 degrees outside and around 45 inside. Furnace not coming on. I went to Home Advisor to setup a quote and I was still considering the three recommendations, when the phone rang. This guy was on the ball! He was at my home in less than 30 minutes and had diagnosed what was wrong, fixed it, made some recommendations, upgraded my old thermostat and got us up and running in no time! He even did some extra maintenance for free. Very good service. Very friendly and professional. We definitely will use him again."

"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."

"Efficient in the insulation process."
Old insulation should be removed when it shows damage, contamination, or heavy deterioration. If you notice water stains, rodent droppings, mold, or large gaps, plan on taking it out to protect your home’s energy performance and indoor air quality. Removing compromised material eliminates health hazards, cuts energy loss, and sets the stage for a safer, more efficient attic—all while keeping utility bills in check.
R-value measures how well insulation resists heat flow—the higher the number, the better it slows heat transfer. The right R-value keeps your home warmer in winter and cooler in summer, saving energy year-round. Match the rating to your climate zone and have a pro verify performance over time, because moisture or settling can lower R-value and cut efficiency.
Attic insulation can stay in place for 80 to 100 years, but its performance often drops after the first 15. As dust, moisture, or mold build up, the material loses R-value and allows heat to escape. Schedule periodic inspections so a pro can tell you when replacement makes sense—helping you keep energy bills down and indoor comfort up.
You can over-insulate an attic. Beyond the recommended R-value, extra layers don’t add efficiency and can trap moisture, leading to mold or reduced performance. A local insulation pro can measure current levels, confirm the right target for your climate, and advise on any adjustments so you avoid future energy or maintenance headaches.
Insulation can be damaged by mold, pests, water leaks, or accidental electrical contact. When the material is compromised, it loses R-value and can introduce health hazards. Removing and replacing affected sections restores efficiency, while routine inspections from a qualified pro help you catch problems early and keep your attic safe and energy-smart.
