"I have been rehabing my moms home to sell and thing have been REALLY stressful. I had two windows that were cracked that I have been looking to get fixed for more than two months. I have had several window companies tell me it was “impossible’ to replace glass panes in thermo sealed windows. I was quoted $10k for one window replacement 😬 Jon showed up like a miracle! He was extremely responsive to my initial inquiry, was onsite promptly to assess the two cracked windows and noticed another window that had a broken seal. He provided a reasonable repair estimate for the three windows and was back to complete the work within three business days! Jon was a lifesaver, his responsiveness allowed me to get the house listed yesterday ! I am SO grateful for Jon!!! If you have windows that are cracked, call Jon to get them repaired!!!"

"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."

"I was having a problem with the glass door of my shower, with the door scraping against the hinged side of the glass. AG Glass arrived when they said they would and completed the repair right then. The door works great, no more scraping sound every time it opens and closes. I'm very happy with the work, highly recommend!"

"From the first interview our sales consultant through the post installation follow-up, we were very happy with the service and work that Excel Windows provided. Sales: We found Matt, our sales rep for Excel, to be friendly, knowledgeable and very responsive to the many questions we had for our large project. Matt walked us through the process of selecting an experienced window installer and quality window, communicating through email, phone and multiple in-person visits, and made sure we were comfortable with Excel’s products and assuring us that we would be receiving the level of service and product quality we desired. Matt always made himself available to answer questions, even after the project moved out of the sales phase and into the installation phase. Installation: During construction, Egor and his partner were very professional and completed the work as cleanly as possible. Of the ~28 windows we had replaced, only a couple required minor paint touchups to the trim and no window trim needed to be replaced. The trim around the sliding doors had to be replaced to allow for door installation, which we were informed about during the sales process. Excel had to be called back out once to fix a piece of warped trim work, but not a major issue. The one thing I wished I had done was ask whether I could buy pre-primed white trim and paint it in advance of Excel replacing the trim around the doors. It would have saved a lot of time in taping and painting the new trim after Excel was done, since they only install unprimed trim. Schedule: The work was completed in about 3.5 days. While this was about a day longer than originally quoted, Excel kept us informed of issues encountered during installation and their impact on the schedule. Leo, the person who scheduled the install crews, was very responsive and accommodating in finding days that worked with our schedule so someone could be home while the work was going on. Product: The Thermal windows we purchased (mostly double hung) are working great and we immediately saw an impact on our electricity bill since we no longer have the 20+ year-old drafty windows that were original to the house. The new windows are easy to move up and down and we like the additional features such as the night locks, screen locks and InvisiScreen. We went with a more contemporary window grid instead of the traditional colonial grid on the windows we replaced, and Excel helped us visualize the windows before ordering them by preparing a mock up of a couple of the windows to make sure we were comfortable with how they looked. We really like how they turned out. We had some issues with the sliding glass doors we purchased in that one of the doors was found to be bowed after installation (factory defect) and had to be replaced. The screen doors had to be adjusted a couple of times so they locked properly. More of a nuisance than anything, and Excel quickly acknowledged there was an issue and did what they could to resolve it as soon as possible. Customer Service: Throughout the process with Excel Windows, we found them to be very professional and responsive to requests and communications from us. Even after the windows and doors were installed and the check was cashed, they called to check up on things and quickly sent someone out if tweaks to anything were needed. As we entered into our first window replacement adventure, customer service and communication was the most important aspect of the project to us, outside of installing quality windows that would last for many years with minimal damage to the surrounding trim. Excel Windows met our lofty expectations in this area, and we would definitely call on them in the future for any window/door needs. We highly recommend them to anyone looking to take on a window and door replacement project, whether big or small, as they did a great job with our fairly large project."

"Robert was extremely responsive and timely. We needed exterior lighting to all be upgraded/replaced before our new siding and soffits could be installed. We were on a tight timeframe. Robert came to give a quote a day after we spoke on the phone, and a week later the work was done. He did it all in about 6 hours. Robert also gave us a quote on some interior work, drywall/ceiling repair and some other things in our kitchen. We will be contacting him soon to schedule this work. We have finally found our do-it-all person. Knowledgeable and so polite. Highly recommend."
