"I was looking to have the floor between the garage and the bedrooms above it insulated. Robert did a thorough investigation and what I needed and made some other recommendations as well. The quote was very competitive and I struggled in my contractor choice. I ultimately went with another proposal. However, I would highly recommend Attic Air and have passed on their information to a couple of people that have asked."

"Gus was extremely responsive. I submitted a request online on a Saturday night and had email contact not even an hour later. He was out to provide the estimate 3 days later, and 1 week later the job was done. I think the price was fine based on the high quality Owens Corning fiberglass blown in insulation used. Nice that Gus does the work himself which adds confidence that the job was done correctly. All penetrating points were sealed up and proper baffles installed along the soffits. After updating the insulation he helped us adjust our attic fan to provide the best ventilation. Overall very happy with the service and they didn’t leave a mess. Good communication throughout and very quick installation. Highly recommend."

"Upon buying our house 18 months ago, we knew we had to add insulation in our attic. From start to finish these guys were very professional. We added significant insulation to bring the R-Value to a total of R-49. They also added ventilation chutes to eaves and reconnected bathroom fans as well. The install team answered all my questions and showed me before and after pics of the work. The crew was on time, neat, and courteous. I would not hesitate to use them again. I highly recommend ARC INSULATION!"

It was clear they care about doing honest work at a reasonable price. The installation was completed efficiently, and the whole process was smooth and stress-free.
