"Jim went above and beyond. We have a cathedral ceiling that had to come down in order to do the spray foam. He hooked us up that night with a carpenter that could do the work. Provided a quote for all before leaving, and then coordinated all of the work to minimize the length of our disruption. There was also some damage done by accident and they made sure it was repaired."

"Jag installed spray foam in the basement, air sealed the attic, and sprayed fiberglass in the attic. The work was done as scheduled. The obviously experienced crew was fast and friendly. The cleanup was great. I definitely would recommend Jag."

"The company could not have been more reliable. Estimate was thorough and detailed, installers were prompt, neat, professional, and considerate. They took time to explain all equipment to us. Follow-up inspection was timely and identified two issues needing correction, and that work was immediately addressed and completed."

"Town Insulation came in on time, inspected and then gave me a quote. Everything was fine. It was really good, it's just that I decided to sell the house instead so I didn't move forward with it. I didn't have any issues with them. I think the price was standard. They were very responsive."

FAQs for spray foam insulation projects in Kendall, 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.
