"These guys took time from their busy schedule came to my residence on Easter Sunday to give me a price on repairing insulation mess left by previous contractor. They arrived next day and completed the insulation work and did an excellent job at an excellent price. My thanks to Sagittarius air seal thanks again, Michael Duffy."

"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."

"I can?t say enough good things about PeakPro Insulation! Before they came out, my attic wasn?t insulated at all and my house constantly fluctuated in temperature. When their team arrived, they introduced me to solar radiant barrier insulation. The difference was noticeable immediately. After the job was done, every room in my house finally felt consistent in temperature, and even my attic felt cooler while they were working up there. On top of that, they left the attic looking beautiful and clean. Highly recommend"

"Roberto was the technician and he was very professional, polite, and personable. He inspected the rest of our system and told us things that needed to be changed or repaired. He showed me pictures of everything. Everything he told me about was accurate. He quoted me a price for R38 insulation , Some of our ducts were plastic and he recommended them to be changed. I agreed completely and didn't know they were plastic. I would have had them done the work but I had no price comparisons to make and besides I didn't have the money right then. So he just finished the vent cleaning and left his card. He did a great job on the vent cleaning and was happy with the work."
