Get matched with top blown in insulation install or upgrade pros in Bourbonnais, IL

"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."

"Natan was very professional from the very beginning. He replaced windows, siding and gutters for our home in a timely manner for a very reasonable price. I will definitely be using them again."

"They did a great job at sealing all of the air gaps in my attic and adding additional insulation."

"Fast work. Great communication up until trying to communicate with project manager. Was told everything would be completed within two days. The roof was done in one which was awesome, but I am still waiting on gutters a week later and won't be given a day/time for them. Just keep being told "early next week" or "tomorrow". Sales portion and inspection went great. Fantastic everything up until the install."

"George came out promptly and did a thorough inspection of the crawlspace and provided options on what can be done. The insulation work was performed by Jesus who also found and fixed two foundation cracks. Encapsulation was done by Juan's team and they all did a great job. They were able to perform all the work with a very narrow opening into the crawlspace and were also able to fit in the dehumidifier. After installation there was a minor issue with the dehumidifier and Craig came right away to fix it. Great experience and I'd definitely use their services in the future if need be."

"Found Arcos on Angie list. Entire process was smooth. My home is cooler in summer and warmer in winter"

"Excellence sums up this true professional business. Troy and his team did a fantastic job removing my old insulation, air sealing and installing upgraded insulation. He was prompt and worked around my scheduled. He does the job himself which was the deciding factor for me. He took before and after pictures and kept me informed along the way. I highly recommend him. I couldn't be happier. :)"
