"This company beat the socks off another company I considered. For one fee, Green Energy removed ALL the blown in and batt and rolled insulation. On the second day, they installed the spray foam. I had another contractor look at the job - and he said he wished he had hired them for his house. If Green Energy had a yard sign - because I would proudly display it. Sweet people and an excellent job. So glad for this recommendation."

"Not only does the roof look gorgeous it's efficient and quiet! It reduced our electric bill along with being cooler, it much quieter. We went with the insulated metal roofing system, which we would recommend, it takes a bit longer and it's more costly but worth the time and money. Frank and his team are friendly, straight forward, and easy to work with. They were efficient and clean, our neighbors even commented how much they appreciated how well they cleaned up each day to keep our road and driveway clear. We would highly recommend them for any roofing job!"

"I was pleased with communication, promptness, and professionalism."
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.
