"I met Robert for an estimate. Robert is a straight shooter, gave a competitive estimate, and no pressure at all. I decided to go with him after another estimate I got was borderline gouging. I was impressed with how efficiently and quickly his crew worked. These guys know what they are doing. Many companies can insulate an attic but Attic Air can also replace attic and bathroom fans. Make sure your soffit though has holes in it to let air into the attic. This was an optional piece for me but the crew chief explained to me the new attic fan that was being installed would burn out if there was not enough air coming in from the soffit for the fans to circulate. I also took advantage to replace two other very old bathroom fans with more powerful Panasonic 100 cfm LED fans to take advantage of the crew being in the attic. My second floor used to be 3 degrees cooler than what the thermostat showed on the first floor, but is now 1 degree or no difference. I am hoping I won't need a separate cooler fan in the summer on the second floor. Didn't need a separate heater for winter at least or shiver unless I brought up the temperature on first floor."

"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."

"We had our old attic insulation removed and replaced, and the entire experience was excellent. Steve Garrett was our main contact. He was personable, experienced, thorough, and responsive. We appreciated his quick responses to any questions we had. The crew that completed the work was knowledgeable, detailed, hardworking, pleasant to interact with, and worked well as a team. They took pride in doing the job right. Since the installation, we’ve noticed a huge improvement in the warmth of our home, and our furnace is no longer running constantly. We’re very pleased with the results and highly recommend Arc Insulation."

"Northern Insulation did a great job, very professional and very clean and timely. We highly recommend them"

"I recently had Attic Pro of New Lenox, IL install blown-in insulation as an upgrade to my existing attic setup, and the results have been fantastic! My main reasons for doing this were to boost energy efficiency and cut down on those skyrocketing heating and AC bills—our old insulation just wasn’t cutting it anymore, especially with Illinois winters and humid summers. Within the first month, I’ve already noticed a huge difference: the house stays warmer in the cold without cranking the heat, and cooler in the heat. For the first time I am looking forward to seeing my next utility bills. The team at Attic Pro was top-notch from start to finish. They provided highly personalized service and paid incredible attention to detail—inspecting every nook, sealing air leaks, and ensuring the blown-in material was evenly distributed for maximum R-value. No cookie-cutter job here; they tailored everything to my needs. "

"I am very happy with the work done by Green Attic Insulation. David and Charlie were very friendly, professional, responsive, and flexible in working with my changing needs. I originally was looking into insulation but then discovered there was mold in my attic. As the job grew, David, Charlie, and their team worked with me to address the additional parts of the job. I really appreciate their knowledge and the thorough job they did. They took many pictures of their progress and kept me informed each step of the way. Thank you very much!"

"Great company to work with. Consultation and estimate process was thorough and transparent. Work was excellent and exceeded expectations. Would definitely recommend them to anyone looking for insulation work."
