Roberto came out, did a blower test, comprehensive walk thru with the thermal camera and we talked about issues and what solutions would work. We came up with a plan. Got started, and discovered an issue. We got together and pivoted to a very workable solution to get the job done. Work was completed well, quickly, and when they were done they cleaned so well you'd never know they were there. Very pleased with the results. Very pleased with their professionalism and ability to find solutions. Couldn't recommend any more strongly!!

The team was professional, friendly, and patient. There was good communication between the team and me.

Chad kept us informed every step of the way, from what work was being done, to the estimates completion date. When he showed up for the estimate, he gave us some options, took some measurements and we had a written estimate before he left. From approving the estimate to the materials showing up was only two weeks! The crew (Andy and Jack) showed up every day ready to work and did so tirelessly until the end of each day. They asked great questions to make sure nothing got damaged or misplaced, and the finished product was better that we had hoped! All scrap was removed and our yard was left in great condition. The job took six days for removal of old material and installation of new siding, soffit, fascia and gutters. Most importantly, the wife is happy!

5-Star Review for Green Attic -- Especially James…read more I had an outstanding experience with Green Attic, and I want to specifically recognize James for his exceptional professionalism and customer service. Companies become great because of the people who represent them and James is a perfect example of that. From start to finish, he was knowledgeable, patient, and thorough. He took the time to explain every detail, walked me through options, and made sure I felt confident in each step of the process. His communication was clear and proactive, and he treated my project with the same care and urgency as if it were his own home. It's rare to find someone who not only knows their craft at a high level but also leads with integrity, respect, and genuine customer focus. Because of James, Green Attic has earned my trust and future business. He embodies what every service professional should be. Highly recommend both the company and James in particular.

Falling behind on this, I was pushing late Nov to get new insulation installed and panicking as temps dropped daily. Robert / Attic Air were booked through the end of the year but they found time to fit me in for 800 sq ft (I think by working an unscheduled vacation Sat morning). They did a great job! They use the Owens Corning fiberglass, non-toxic and clean! Did not try to push or upsell me. Didn't push the toxic cellulose (don't want toxic pesticide saturated paper in my attic, we breadth that air!). They are pros and they do insulation very well!

Robert was great. Trustworthy, prompt, communicative, everything you'd want. Highly recommend…read moreworking with Attic Air and Robert, thank you!

I live in a ranch home built in the 1950s - a fairly common build for the Chicago area. ARC…read moreprovided a quote ( without visiting our home) that included the following sentence, "Please confirm exterior walls are framed 2x4". I told the rep that other companies have inspected our home and stated that our walls are suitable for blown in insulation. ARC never came to visit our home - while their competitors did this as a standard account management cycle. Fast forward to this week, I was ready to sign the agreement and pay the deposit - the rep asked me to confirm the 2x4 framing. I asked him how he wanted me to do this - he suggested I drill pilot holes in each wall or pay a 3rd party to do this and that ARC was not responsible for verifying the details of our home. Not responsible for validating a critical project detail before having you customer pay thousands of dollars?! Extremely poor customer service and frankly, a lazy sales team. I am sure the crews doing the work are great, but the accounts team could use a refresh. I will work with a competitor unless ARC has employees willing to visit their prospective customers!

He was able to help me convert my garage to a gym by insulating the roof for me - which has made it possible for me to work out in the winter there. He also had his team insulate my entire house as well as do some ventilation work. The work was great, fairly priced, and they were responsive. 5/5, would recommend to anyone.

We purchased a home built in the 1950s that was (almost) fully renovated in 2013. Our inspector…read moretold us the insulation looked like it hadn't been refreshed in 40 years and was severely deficient by modern standards. Jim was one of a few companies that I received estimates from for insulation, but he was far and away the most thorough and descriptive. As a first time home owner, I didn't know a shingle from a soffit - Jim made the whole process easy to understand. Further, his report on our home after the estimate was like a graduate thesis, but in layman terms. I'm far more educated about my home after working with Jim, and I finally have adequate insulation in my attic and crawl space. He was also reasonably priced (competitive with another estimate and 1/3 of the most expensive estimate that we received). TL:DR - I would recommend Jim and his team to anyone looking to up their insulation game (he also does HVAC and Solar, although we weren't in the market for these).
