"Chicago Window Guys provided me with 8 replacement windows in my condo unit. The windows were fitted very well, and they were able to remove my old windows and install my new windows in a very timely manner. In addition, they were able to replace windows on the fourth floor of my building, while many other companies I contacted were not willing or able to do so! The warranty they provide with their windows also provides great peace of mind."

"Did not recieve the estimate after the consultant arrived. When I called back received the estimate very quickly. However the estimate was over 20K for 15 plantation shutter windows which is about double any of the other estimates."

"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."

"We have not had our window treatments installed yet, however Dawn has been very helpful in answering our questions and guiding us on what to choose for our windows. She went above and beyond to make sure she was present during our shutter measurement appt with Andy. I can't say enough positive things about her and your company so far. We can't wait until our window treatments are installed!!"

"The customer service from choosing the window treatments to having them installed was excellent. The communication was always prompt and professional. We would definitely recommend their services."

"Excellent workmanship and products I have had three installations with Power in the past two years. I first used them for a new roof and gutters. The workers were all knowledgeable in their area of work. Clean up was good although some nails kept showing up over time. Next I had the 2nd floor windows and some 1st floor windows replaced, 9 in total. Installation went well and they cleaned up beautifully afterwards. I love the windows! They are a beautiful and energy efficient product. Lastly, I recently had a bay window replaced in my kitchen with the same type window. The workers ere all friendly and explained what would be done. The area was draped with plastic to cut down on dust. Clean up was excellent inside and outside! The window is beautiful and the framing on the outside of the window matches the other windows and the small roof above the bay window was replaced with the same roofing as the rest of the house. I would choose them again for any future projects."

"I am very pleased with my new windows. I used Home Genius Exteriors to do my roof, gutter protection, and now Windows. This is an absolute amazing company, my salesman brendan was very helpful, Devan the Project Manager helped make sure everything went smoothly. Walter and Mike also from production were very friendly and professional. And Shawn, the window installer was polite,knowlagable, and efficient. And even cleaned up on his way out. Next on the agenda is to get a new door taken care of. Highly recommend HGE"

"We wanted electric blinds to tie into our home automaton. Bumble bee patiently advised us and helped us choose the best solution. We couldn’t be happier with the results. It’s so cool to have voice controlled blinds!"

"Love my new windows! The installers were such pros,,, I had wood shutters that needed to go back exactly and no problems! So pleased with the experience! Jack was patient with multiple changes and decisions!"
