"They did a great job and were very professional. The old insulation was put in a dumpster and most of it stayed in it. Was very pleased with their work.

"This company cares. They put people above profit. I was in a bad situation, after a nasty winter my roof seemed to be disintegrating before my eyes. It went really fast. Then Daryl stepped up to help me out of a difficult situation. Within hours they expedited the crew, and Walter and Lauren ordered materials and made my roof a priority. Now with three days of rain coming I know my house is protected and it looks gorgeous."

"Brad, the salesman came out and gave an estimate to spray foam insulation under entire cottage. Unfortunately, i was not there when he came, so he didn't have complete access to the crawl space. The original estimate was around $2700 to spray the entire space. We scheduled a time/day. The service techs came that day, but many hours later than I was told by the salesman (not their doing). However, when they did arrive, they were extremely professional, efficient and polite! They were definitely experts and highly trained. I encountered some issues with "access" to certian areas under the house. They did what they could, explained and showed me the situation. Since they were unable to spray all quoted areas, about 560 sq ft., I was given a refund on that portion ( about $1000). The guys were great to work with, very honest and qualified. I will use them again. I feel the price was good - another company quoted $1200 more.

"They did a great job. On time both for the estimateand the installation of my blown in insulation. They cleaned up and were very nice. Highly recommend."
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.
