"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!"

"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. "

"If you are looking for a company that couples outstanding work with outstanding customer service, then Green Attic Insulation is who you should definitely call. I truly wish I would have called them years ago as I have been putting off suspected issues that centered around extreme temperature fluctuations between winter and summer, along with poor ventilation, within my attic. From the time that Tim arrived for assessment after great communication from Alina, to the installation of the insulation and solar fan with Charlie and his team, to a final blower door test, every aspect was performed professionally and as outlined by the quote. The issues identified were explained thoroughly, with the after result reviewed with me to ensure it was completed as expected. The company must take pride in the people they hire because it showed with their skill and personalities. They were great to be around that day. As for pricing, I originally expected the final quote to be much higher, but found the quote to be very fair and reasonable. So again, if you are looking for quality on a job done right, I definitely recommend that you call Green Attic Insulation. Mark S / Grayslake"

"Mike explained the procedure very well. He answered all my questions and was very patient with me. The crew was very professional and attentive to their tasks. They cleaned the work area before they left. I was made to feel very comfortable with the whole process. The insulation has made a significant difference in cooling my home. In this heat the upper level has remained very cool. I highly recommend this insulation method and this company."

"This is my first Angies List review and it could not be more deserving. Crew showed up as scheduled and made sure hallway and bed room path were covered. Sprayed 15 inches of insulation (R-38 insulation) of over existing insulation in attic. No dust or debris left behind in bedroom or closet (attic entry way) Overall Trela Roofing did a very good job for us from the bidding till the insulation itself. We highly recommend <br /> <br /> <br />"

"Nick and his crew were so informative and pleasant to do business with. We had attics insulated, new vents installed, and outside blown-in cellulose, and they worked long hours to make sure everything was done correctly. I would definitely recommend this business. A great surprise was how the insulation muffled loud outside noises (fireworks and loud vehicles)."
