Energy Attic installed a radiant barrier in my home. They were fast and they were neat. The only reason I gave them 4/5 was because it was kind of a little more expensive than I expected it to be. However, that didn't keep me from doing it! I will find out if it's worth it this summer. I really liked the salesperson who came out and gave us the quote. He was nice and professional, he got to the point, and didn't try to oversell us. I would go back to them again if I needed something like that done again.
