"They did a great job replacing and securing old drywall in our garage. They installed an electrical outlet which works perfectly but his suggestion, to make it easier, was to use BX which is not code in the area. Luckily I knew that because my parents would have gone with it unknowingly. I definitely wouldn’t hire them for carpentry work. We had a prehung front entry door put in and screen door reinstalled. We ended up having to have someone else come out and redo the job because they installed it so out of square that you could see daylight and the screen door wouldn’t close unless you pushed it with all your weight. They didn’t replace the interior trim or the piece of flooring they pulled out. They did a good job installing the peephole, mail slot and handle. Would recommend for small jobs but nothing too involved. Definitely not electric or carpentry."

"We were very happy with the repair of the hinge on our storm door. He repaired it by replacing a few washers that has gone missing. Other repair people recommend we replace the whole door."

"Just moved in and wanted to have our system looked at, especially since it's getting up there in age, and see about getting a service contract. Jamal was absolutely the best and I signed up for the service club right off. I'm one of those that likes to know how things work so we chatted, he explained things he was doing, talked about refrigerants and where the technology is going. Suffice to say I absolutely recommend calling Windy City for HVAC concerns."
