"Did a great job on the insulation however they left a hole in the ceiling when they dropped something on the attic floor. Not a big deal but they need to be careful. Overall, amazing work they do all kinds of insulation and they also install radiant barriers on roof joists. They are reasonably priced and the crew is super friendly, pleasure to work with."

"Our primary bedroom is above the garage and even though we have a newer home, you can feel cold air coming thru the floor. It's the coldest room in the house by far. Ed's team came in and placed foam insulation in the garage ceiling. He gave us $100 off for Angies list discount which was nice. They cleaned up well when done. Now that it's warm out I can't grade the quality of the work until winter again because I won't know till then if its helping with the problem. I will come back and update then. We had been quoted over $6000 by another company to do the work so hopefully this works and comes in far cheaper.
