"I called Chuck Davis (Insulation Guys) last Friday and he was out to complete the job the following morning (Saturday). It's 17 deg this morning and the garage is 57 deg (with no heater on) when it would have been in the mid 40's prior to the ceiling insulation under the same conditions. I'm extremely pleased with the job done! He even added a bit of insulation in a spot near our front door (next to the garage) were he noticed the insulation not close to the R38 level it was supposed to be. The whole experience was great. They were personable, professional, and a pleasure to work with. It was like having a good friend perform the work. The Insulation Guys more than lived up to the excellent reviews on Angie's List and highly recommend them without qualification."

"We had existing attic insulation removed and new insulation blown in. Net Zero's staff was extremely professional. They did a great job and cleaned up afterwards, and left the house cleaner than when they began. I would definitely recommend them. They are one of the few companies who offer financing as well."
