Great experience from start to finish! I highly recommend Comfort 1st Insulation. Quick turnaround for an estimate and installation. We got insulation blown in the attic and above the garage.The entire team was very professional, courteous, respectful and clearly took pride in their work, going above and beyond. When they left, you wouldn't have known they were there with how well they cleaned up. We noticed a big difference immediately, with a more consistent temperature throughout the entire house and the second story is much more comfortable, as well as no more freezing in the garage. I will definitely use them again if needed in the future.
Everyone at Comfort 1st are wonderful to work with ! I recently got my attic insulated with them. Overall, very pleased with team and the work, I would highly recommended them. I received several quotes from competitors, but, David from Comfort 1st, was the only one to detail out all aspects of the job and was thorough in explaining the process. Mike was also great to work with and really knows his stuff. The crew who came onsite did a wonderful job in preparation and cleaned up once they were done. Overall, great communication with all team members. Once again, great company, would highly recommend them.
We had a fairly large job. Insulation removal, installing exterior bathroom vents, attic cleaning, sanitizing, and making sure no critters could come in, foaming many areas, and finally blowing in new insulation. Josue and his crew were amazing. For 2 long days they worked incredibly hard to ensure that the job was done correctly. They cleaned everything when they were finished, and even showed us photos of the work as it progressed. We're extremely pleased with Comfort 1st, and highly recommend them. Thank you Josue and crew, Allie and Mike for your kindness.

We had a great experience with Greenlink from beginning to end. The sales person was very helpful. The planning staff and office staff are responsive and polite. Installation was scheduled faster than I thought it would be, and the installation team was terrific. They worked very efficiently on some of our hottest days of the summer, and yet managed to be polite, responsive, competent, and pleasant. I don’t use subcontractors; they did the job themselves.We felt completely at home having them In and around our house. Finally, they’ve been very responsive in getting the post installation incentives and rebates that are part of the package.We had a great experience.
Today a crew installed Solar Panels at my resident in Lisle, IL (Angela C.). I am more than satisfied with the results. The Team arrived according to schedule, was very professional, walked me through the installation process, checked with me on several occasions to make sure I was pleased with work performance, and they were also very respectful of my home (removed or covered shoes, placed plastic covering on the floors, cleaned up debris inside the home and in the yard, courteous of noise level as I worked remotely). A very special “Thank You” to Kevin, Joe and Nick for going the extra mile! They were friendly, provided excellent customer service (I am known to be meticulous), made any reasonable accommodations and kept me informed throughout the process no matter how minor the detail. Job Well Done!!!
They were easy to work with, got the job done quickly and professionally, and have been great about answering any questions I have after the installation is complete. Their work is very clean and the panels look great, no extra conduits snaking across the roof and the panels are all nicely arranged. The in-office staff walked me through the process and answered all of my questions without the condescension I got from other salesmen. I liked that they are local and have been in business doing electrical and insulation work as well as solar for much longer than other companies I got quotes from. I would and have recommended GreenLink to friends and family.

Had a new garage built and Josh from Metro came over measure and gave me couple different options and recommendations of what was best. Very transparent and honest. The price was good. They did an amazing job. Very professional and knowledgeable.
Foam Slab Jacking I recently worked with Metro Insulation in Rockford for concrete foam jacking to lift and level several sunken and uneven concrete slabs, steps, and a ramp around my property—and I couldn’t be more pleased with the results. From the initial call to the final cleanup, their team was professional, punctual, and experienced. Josh walked me through the entire process, explaining how they would inject high-density polyurethane foam beneath the problem areas to raise and stabilize them. The work was done efficiently, using relatively small injection holes, and the crew was extremely respectful—especially when working inside my home and in the basement. The slabs were challenging to lift, but they got them level again. They filled some voids under the concrete as well and made sure that the concrete is solid again. They also went the extra mile to protect nearby finished surfaces throughout the job. Overall I could not be happier with my decision to use Metro Insulation for foam slab jacking.
I'm 70 a year ago I bought neglected home. No insulation was the least of many issues but the first I addressed. No regrets! January I crawled from beneath electric blanket it was 44° in living room the furnace died. Would've been worse without insulation. But The Best Thing Was I Had Insulation Done In Basement and bugs that overrran my house last summer weren't an issue this year. Somehow insulating top and bottom saved Pest Control twice yearly (according to neighbor previous owner did do that). The bugs stay outside.
