"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."

"We hired ThermaCore Insulation to remove our old attic insulation, air seal the attic, and install new insulation. Kamal and his crew were professional, honest, and easy to work with from start to finish. During the inspection, they found several air leaks and duct issues that other companies completely missed. They explained everything clearly, completed the work on time, and left the area clean. We noticed a big improvement in comfort right away. Great service, fair pricing, and quality workmanship. Highly recommend ThermaCore Insulation!"

"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."
