"I highly recommend New England Performance Insulation!!! Having no knowledge of or experience with foam insulation or the process, I really lucked out w NEPI! Vernon explained the process in a way that was easy to understand, which made me feel very confident in hiring them and in the choices we made with specifics to the job. The crew was amazing - on time, professional, so nice, hard working, and clean! Vernon went above and beyond to make sure everything was to my satisfaction and even came back to do some additional touch ups to make sure the job was 110% complete and to my satisfaction. And a huge shout out to Carol in the office; she is so sweet, helpful and professional. A great asset to the NEPI team! Not only do I highly recommend foam insulation for your home, but I highly, highly recommend hiring NEPI to do the job! Vernon is a super nice guy and he will make sure you are a super happy customer!!!"

"Ecofoam insulated my attic with closed-cell spray foam and the results came out great. The space feels completely sealed and much more comfortable already. Sevi and the team were very professional, easy to work with, and kept me updated throughout the whole process. I would highly recommend EcoFoam for anyone looking for quality insulation work."

"They were very professional, took care of helping me get the home energy audit and the rebates for attic and wall insulation. Also improved attic ventilation installing soffit vents and baffles. We got three estimates and they were a very good price, but the service is what sold us."

FAQs for spray foam insulation projects in Stamford, CT

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.
