"I love this company! Garrett came to my home and assessed how efficient our current insulation, etc was. He was very informative and friendly — explained what we needed and how they could help. At the time, I decided to hold off and he never pushed the sale. When I was ready, he was quick to accommodate my schedule. His team: Angel, Luis, Tommy and TJ were great! They arrived early, were professional, courteous, kind, very helpful with my questions and were above and beyond to help fix things that I wasn’t even aware of. They also were more than happy to help with small problems that I had no idea how to fix. They worked quickly and cleaned up afterwards. You could tell they cared about their work which makes me feel confident that the job was done right. They were also fun to have around — my Great Dane loved them too! Garrett and Dave checked in with me during and afterwards to make sure things were going well and if I had any questions. I highly recommend Eagle Shield."

"American Attic was everything they promised. Met with the owner , Sam, within a day to get a quote for removal of old insulation, rodent control and install of new insulation. He was professional and explained everything in detail of what was work was going to be done and how long it would take. We scheduled within a week at a reasonable price. His crew were neat, organized and finished on time! We were notified of some extra things that were found while they were on the job but were not pressured to have those things done. We recommend American Attic to friends or family and would definitely use them again."

"I was impressed with Aaron, the owner. He thoroughly explained what he was going to do, and took before and after photos of the job. I have noticed a big difference in the comfort level of my home. The HVAC unit rarely kicks on, as the insulation is holding the temp much better."
