"Jim Clay gave the most comprehensive quote for our insulation project. He suggested a couple of options which thought would help regulate the temperature in our home. He explained everything that ARC insulators would be doing to our home. He told us about rebates that would be credited to our bill because of a blower door pressure test and gas appliance combustion test. He presented a well-written quote. The technician for the tests and the technicians who did the insulation work showed up on time. They explained everything they were doing thoroughly. When the work was done, we did a thorough walk-thru before the techs left. We are satisfied with the work performed. We are satisfied with the money we paid. We would recommend ARC Insulation to anyone seeking recommendations."

"We chose Attic Pro after getting a few quotes. Their representative, Ryan, was incredibly thorough. He performed a energy audit for us. The consultation was professional and informative, with clear explanations of the process and expected values. We are pleased with the work that was done by them. If you are dealing with a drafty house or high energy bills, a professional insulation upgrade is a game-changer. I highly recommend Attic Pro. Thanks again Ryan! Cesar C. "

"We badly needed insulation in our attic. We got three quotes. Weather Shield was not only the most reasonable, but the only company in which the owner both gave us the quote and installed the insulation with colleague. We could not have asked for more professionalism or better service. Would highly recommend Gus."

"Alex and his team were prompt and they did a very good job on the insulation project. The team worked well together and they were efficient. They picked up the trash in the attic before blowing the new insulation. The work was done with complete satisfaction and I highly recommend this company. Keep up the great work!"

"PermaSeal is the Best. The consultant clearly explained the options for my project, the scheduling and cost. The installers were on time, explained questions I had about the basement crack sealing and Permafoam installation , completed the project in a timely manner and were friendly. This is the second project PermaSeal has completed for me. I would call them again, for sure."
