Commercial and Residential Insulation Contractor in South Barrington, IL

Highly recommend! Green Attic is thorough, responsive, and professional. Although it has only been a month since we had the work done, the results are clear. Our house is more comfortable, while our gas consumption is down ~30% and electricity is down ~25%. I live in a 100+ year old house with a finished basement and three floors (including the basement). The house was renovated about 20 years ago and the walls were insulated, but certainly not up to modern standards. To save energy and lower our GHG emissions, we hired Green Attic (GA) to insulate the top floor as well as parts of the basement where they discovered cold air was leaking into the house. On the top floor, they sealed all the fixtures and blew in cellulose insulation between the ceiling and the roof as well as into the knee walls down to the level of the floor. There is no access to the attic space and there is very little room between the ceiling and roof, which means GA had to cut through the ceiling/ walls and then maneuver in a tight space. They did a great job keeping the number of punctures to a minimum. They also blew insulation into about 2/3 the basement walls, primarily where pipes come in/ out and there was cool air making its way into the house. James conducted the initial inspection and provided the estimate. I gathered quotes from several companies, some of whom recommended different approaches, but I found his suggestions/ explanations the most compelling. Green Attic was slightly more than a couple other companies, but in the same ballpark. I went with GA mainly based on reviews and James' explanations. Alina, in the home office, was very quick to respond to any questions/ concerns I had. The crew worked two full days. They were punctual, courteous, responsive to my many questions, and careful about containing the mess. At the end of each day, they walked me through the construction areas to make sure the cleanup met with my satisfaction. Just as important, they left the impression that they were intent on doing the best possible job (rather than making the most possible money). With an old house, you are always nervous cutting holes and opening things up. Will you discover something that adds new costs? We had one issue with some old cheap drywall that collapsed during the process of blowing in insulation. GA fixed it, no problem. In one of the upstairs bedrooms, more work was required than expected, but they just dealt with it. In the basement, they ended up doing slightly more than I expected. Overall, I got the impression that they take pride in their work and were looking for every possible way to make the house more energy efficient. As noted, I'm very pleased with the results. We've started saving on energy costs and we haven't even gotten to the coldest and hottest months when the real cost savings should kick in. The house was not uncomfortable before the work, but it had cold spots and could take a while to warm up in the morning. Now, the cold spots are gone, the house warms quickly, and the furnace that serves the top floor seems to hardly ever kick on. The basement is actually warmer than the main floor; part of me regrets not having them do work there. Bottom line, you cannot go wrong with Green Attic.
