"They are the answer to lower energy costs and better comfort. In my area, home builders applied minimum standards when it came to insulation. Performance Energy fixed it and made it right. We could tell the difference overnight. Plus, they file all gov't rebates for you. Very grateful."

"Awesome experience. Purchased home with open crawl space that was deteriorated with hanging insulation, and breeding ground for rodents and waste. Researched crawl space options and interviewed several companies to compare. Greg was honest, informative and provided an option that encapsulated the raised crawl space, complete with dehumidifier and thick vapor barrier. He promised to come by annually to check and make any necessary adjustments and stood by his word - we had the project completed in 2015 and he came back in 2016 adding some sealer to small gaps that occured and will be scheduled him again to return soon for 2017 service. VERY happy we completed - the house smells much better (they disinfected underneath and spent time ensuring joists were clean), air quality and comfort level is greater and greater peace of mind with rodent exclusion. Would HIGHLY recommend Greg and his crew"

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.
