The crew made a small error by not plugging my sump pump back in. I had some water in the basement but Mike made it right by me, he is a man of his word. I would definitely recommend.read more

I shopped around local contractors and companies in the area but Comfort 1st made it the easiest process. It only took... 3 days from the time I called to getting a quote for my garage attic and sun room and then being out on the schedule. Extremely fair prices and they are very upfront with information, answered every question I had. Crew was respectful and made sure I was cool with everything. I'd recommend them to any neighbors who asked. Thanks!read more

We were extremely pleased with Comfort 1st Insulation from start to finish. Everyone we dealt with was extremely... helpful and cordial. We had insulation blown around the exterior of our basement to make it warmer. We also had a mice issue so this has kept the mice out as well. They stuffed steel wool around the exterior of the siding to prevent any more mice from entering. The install was outstanding. They did all the prep work and we didn't even have to move stuff out of the way. They did that for us. After the install they cleaned up better than when they started. I would highly recommend them if you planning on having insulation done.read more

We had a great experience with Comfort 1st. Mike was very helpful and answered all of our questions. He spent a great... deal of time during the assessment and energy audit explaining how the job would be done and why it was beneficial. The price was competitive and the Nicor rebates we were eligible for made the work a great value when compared to other estimates. Mike's team was great, and Mike himself was hands-on during the whole process. Mike has checked up on us several times since to make sure we are satisfied with the work, and we definitely are. If you are considering making your home more comfortable and energy-efficient, we recommend Comfort 1st!read more

We purchased a cape cod style home this year. After living here for the summer we found that the upstairs was extremely... uncomfortable and would not cool down. As it began getting into fall time the upstairs was 10 to 12 degrees colder than the rest of the house. We suspected the insulation wasn't done very well in the attic. After doing some research we found that cape cod style homes are notorious for this problem and can be very hard to properly insulate. It made us very nervous as our kids rooms are upstairs. Mike from Confirm 1st came out and took a look and explained that there were many problems with the way the attic had been insulated. He assured us that he could fix it for us and our children would be able to be comfortable in their rooms. He sent his crew out and they installed batting and blown in cellulose. They also airsealed all the floor joists and around any vents, light fixture and outlets. After a couple weeks it didn't seem like there was much improvement so we called Mike back. He came out and took a look and realized his crew had made some mistakes. He spent the entire day personally fixing it. I was nervous that because they had to spend much more time than they quoted that our bill would be larger. In fact he gave us a discount. It is like night and day the difference it has made in our home. I am thrilled with the work and the improvement. Mike and comfort 1st stood by their work and made it right. I would recommend them to anyone looking for insulation improvements. THANKS COMFORT 1ST!!!read more

These people are the best in their covering area. Do not confirm your project until you talk to Comfort 1st. These... people are sincere, honest and do every effort to save you, if you can get any rebates from ComEd etc. Their price is very reasonable. Mr. Mike is a gentleman, courteous and helpful. I will be happy to call them for any future services and have no hesitation to recommend to my friends and family. My sincere advise is talk to them, get their quote, then decide. I am sure you agree with my comments. I wish them all the best.read more

Absolutely loved working with Comfort 1st Insulation. They were reasonably priced and did an outstanding job. We had... insulation blown in on the exterior walls of the basement. It has definitely made a difference in the temp down there. We were also having mice issues so this will keep the little critters out. They also put steel wool around the bottom of the exterior of the siding. Double protection so I never see another mouse again. Everyone I have dealt with at Comfort 1st Insulation was so helpful and a pleasure to work with. When the guys came for the installation, they prepped the entire basement and we didn't have to move anything. They did it all. They also did a great job with clean up.read more
