"We hired Energsmart Insulations to insulate 2 sides of our house because of some rather loud neighbors. Their price was very reasonable, they even bumped our project date ahead of their schedule because of how loud they were. Once they started the project they found that all of our plywood between the siding and studs were beyond rotted. They even showed my wife and I that some of the siding was not even nailed to anything because of how bad the rot was. They could of easily just injected the insulation under the rotted plywood but they told us they do not feel comfortable doing that because it would all torn our when we reside. We decided not to do the installation because of the unforeseen rotting issues and I really appreciated their honestly. They could of just did the work, put the siding back on and we would never have known the extend of the problem. Once we get our house resided I would definitely go with this company to insulation our home."

"The company was very professional and did a good job for us. They are not cheap, but did offer a discount for a combo job for both gutters and insulation. Their crew was meticulous and did a very good job with clean-up after the work was completed."

FAQs for insulation service projects in Buffalo, 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.
