"Daniel went above and beyond, not only removing the old insulation and replacing with new, but fixing other issues he found in the attic. I felt that I had hired the absolute best person to do this job. He and his brother are great workers, did a fantastic job, and cleaned up afterwards."

"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."

"My attic was poorly ventilated — damp, musty, and overdue for attention. After deciding to bring in a professional, Randy came out to my home, thoroughly assessed the problem areas, and put together a detailed quote on the spot. The scope of work included removal of the existing insulation, air sealing around all attic entry points, sanitizing, air baffle installation, and installation of new Weather Blanket cellulose insulation. The new cellulose achieves an R-value that meets or exceeds Illinois code requirements. I couldn't be happier with the results. I've already noticed a meaningful improvement in temperature consistency and overall comfort throughout my home. If you're looking for a trustworthy, professional insulation contractor, I wouldn't hesitate to recommend Paragon Insulation & Services."

Customers say: Quality work

"Neil and his team did a great job installing new attic insulation in my home. They did a thorough job of removing all the old insulation, repairing the bathroom fan vents, fixing the soffit vents and spraying all new insulation throughout the attic. I highly recommend Neil and team. They were professional, courteous and I am highly recommend them."

"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."

"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"

"Dan did a great job insulating my attic. He did exactly what he said he would do, on time and at the quoted cost. He was very thorough in his work, applied foam sealant, installed baffles, installed bathroom vent access thru roof and installed blow in insulation. Nice guy as well. I'd hire him again."

"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."

"Emily was the product manager - she assessed the insulation we had, which was very inadequate, and gave us a range of upgrade options. A team of three guys did the work, solving some of our problems in a very resrouceful way. Then Emily came back and checked everything over. We were very happy with both the work performed and the customer service. The house feels unusually toasty now. We'll update this review in the spring after we see if we get our usual ice dams - hoping they're gone forever."
