"We had been in the market for new windows on the back of our house for some time but just had not made a decision due to the number of windows, the cost and indecisiveness in design. When a Rogue Golf Ball shattered one of our windows we were forced to make a decision. We contacted The Chicago Window Guys after seeing the spectacular work they did for my Neighbours home. I was connected with Mark who present us with a lot of options but made it very easy to make a decision with out being overwhelmed. The area of our house which we had re-windowed was very odd as it was 2 stories of 10 sliding glass doors in the 4 season room (5 on top and 5 on the bottom) installed by the original owner. Mark presented us with some great options. Once we came to a decision the work was scheduled and everything ran smoothly from start to finish. Mark was always available to answer questions, the gentleman that measured the windows was on time, speedy and had a great customer service persona. The guys installing were friendly, professional and cleaned up after themselves. I have more windows to replace and will be calling Chicago Window guys when that time comes. We also decided to have them do some of my other doors and will use them for many other projects in the future. I even told all my neighbours how good the work was. Several neighbours have since had them do work on their home as well. Besides the windows which we love we also had a back door replaced. Our 4 season room is no longer cold and drafty in the winter and we are so happy for the work. We have held several family functions in this room including a large Thanksgiving and Christmas gathering – which we would have never been able to do previously. Thank you Chicago Window Guys!"

"Windows are good. Work was sloppy. Still finding shards of glass on the floor and the furniture a week after completion. Caulking looks like a third grader did it- including caulking the screen door to the frame. For this type of investment, they should act like professionals."

"I am sure this company is fine but my plumbing problem turned out to be an EMERGENCY issue, so I had to call another company that could come out immediately."

"It went great! Very professional, friendly, and helpful! They did a great job."

"John has been nothing but professional from day one!! I request a quote on a Friday evening through both their website and Home Advisor and John called Saturday to set up a time to come look at the roof and give us a quote. We set the date of the job and they arrived that morning and wasted no time in getting started. John was on the job site, and even climbed up on the roof to assist his crew. They were very thorough in not only the job, but the clean up after. They ensured all nails and excess materials were removed. Top notch job and would definitely recommend them to anyone getting a roof either repaired or replaced!!"
