"We got a couple of estimates to spray the cellar sills where the house meets the foundation. We chose Foamcoinc because of the knowledge of the person that came and gave us an estimate...I think his name was Dave. He had some good ideas on how to spray and seal under the bay windows, left samples of the foam with us, and some more information. I thought that was great so I could make a more informed decision. Not to mention the 'R' value of the foam he would use was much higher than the other company's and he price matched the other company's price in his estimate! They showed up about a half hour early, which was slightly inconvenient. Thank goodness my husband was home since I just got out of the shower when the doorbell rang. They came in and went right to work. They did everything they said they were going to do and a bit more than expected. The thickness of the spray insulation was thicker than they specified and they were neat and clean! A great experience! Try them out for yourself! I will be calling them for when I am ready to do the attic."

"We recently had our house insulated with Metro NY insulation and we had the best experience! We had gotten a new heating system and were finding it wasn't warming our house to it's full potential, so we realized it was because the insulation wasn't done well in our attic. We called Metro NY and Jay came by very quickly. We had called multiple other companies and Jay was the first one to show us first hand, what the insulation would be like with a demonstration, and also took the time to look into all aspects of our home, and explained the entire process to us. They also were the most affordable by far compared to other companies. His team was very friendly, and efficient, and we can feel the difference already not even 24 hours later! Highly recommend Metro NY Insulation!"

FAQs for insulation service projects in Cornwall, NY

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.
