Dynamic was responsive to my calls and texts, communicated well, and ultimately did a great job with the door installation. It looks great and is exactly what I was hoping for."

"Jon came out measured my window and was back within a week to replace the bad window. Very professional, worked around my business timeline and was proficient. I will be referring him to anyone I know with bad windows! I catch myself gazing out the window now that I can see out of it."

"Prompt and professional.Solved my problem on patio sliding door."

"It went extremely well. Being female, many contractors gave me obscenely high quotes and didn't detail out prices (which I requested). Working with John at Best Windows was such a pleasure. He listened to my needs, was candid, honest, and detailed out pricing. Also, he provides the highest quality service for the best price. His team (pleasant & professional) Installed 14 windows. I expected minor issues. And John/team were quick to respond and fixed them immediately. I highly, highly recommend Best Windows."

"The Chicago Window Guys is a great company to have install your windows and doors. the owner Russ came out and was not aggressive or pushy like other companies. He was patient and truly listened to what me needs were. Since I have a big home I wasn't able to have all my windows done at once. This was ok! Russ worked with my budget and I got a new patio door, kitchen window and living room window. I was concerned about how well they will block out noise since I live close to a train track. The door and windows are great at reducing noise and keeping my home cool in the summer and warm in the winter. The installers were professional and did a great, high quality and thorough job. Will use this company again to get the rest of my windows done."

"Excel, did an excellent job answering our million questions and was courteous. We had an issue that wasn't Excel's fault. My wife wanted the patio doors that has the blinds inside the window. But the last update that Excel received from our village was it doesn't meet code. So we had to go with the regular patio doors. So once the windows and patio door was replaced, the village had to approve it. So as the village inspector was doing his job, I took it upon myself to ask why the village doesn't allow patio doors with blinds inside the windows. The inspector informed me that we can, the particular code was changed some time back. Excel wasn't aware of the change, so we immediately called Excel informing them of what we just heard. Excel without hesitation got us the windows that my wife originally wanted. Excel made my wife happy, which made me happy later on that night & that night our patio doors were changed to the ones she wanted!!! Thanks Excel!!"
