Best glaziers near Markham, IL

"The results are really nice, but just took too long to complete, otherwise our project would have been rated "A". The process started in late September 2019 when we were asking for estimates. We really liked working with Teresa and selected Excel for the project in November 2019. We got scheduled for January 6th, 2020 to start a project which was to take 2 to 3 weeks. Roman did the remodel and he was fantastic. Great workmanship and easy to schedule with. While 95% of the project was completed in three weeks, delays with the walk-in shower glass and the linen closet doors pushed that remaining 5% completion out weeks. Covid-19 then added to the delays. The linen closet doors were finally delivered on May 5th, 2020. We are happy with the end result, even after the delays."

"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!"
