Absolutely amazing! The first year, we had only done the upstairs. We went from four mild winters to one terribly brutal winter and our usage dropped by one third. However, with the basement being uninsulated, there was always a cold wind blowing up from the basement! The upstairs was wonderfully warm, but the basement was just as if I was outside! I had to put on a winter coat just to go downstairs to do the laundry. The next spring, I immediately had Pete come back to insulate the basement. Af

When Pete came out to quote I was so impressed with my first impression that I made my choice before he left. I had considered DIY but, despite the higner cost, the result (and research on retail cost of materials), I am vey glad I hired Pete. The installers were couteous, prompt, neat and thorough. Rated 12/10.
