"Troy was friendly, efficient and knowledgeable. I would highly recommend him for any insulation job. After insulating my parents home he was hired by my sister for her home and I’m getting a quote for mine also."

"We are finishing our basement. We put up framing, insulation and paneling only to discover we had a condensation problem. We contacted a locally well known water damage and restoration company. After waiting two weeks, they called to tell us they were not interested in working with us. During these few weeks, we tore down the paneling and insulation. We contacted Superior Insulation after noticing their great reviews here on Angie's List. We talked to Rick who gave us an idea of what the solution was and set up an appointment to view the problem area. Once he saw the problem area, he decided on a slightly different solution. Contract signed 3/18/15. Work completed by Rick and Jim 3/30/15. They were very professional, thorough and nice to deal with. We are very happy with what they did.

Same quality and company, NEW NAME!!!! Yep we've upgraded our branding to better reflect out company goals. As always, quality products are essential for success, but without certified and trained technicians installing everything to the exact specifications for greatest success, your home wouldn't get the best results. That's why we do things right - every time. Our excellent products come with extended/lifetime warranties INCLUDED - there will never be an upcharge for a warranty. The adage "you get what you pay for" is 100% true for Insulation Geniuses. We'd rather explain the investment up front rather than trying to explain quality for the next 20 years...

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.
