"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."

"Premier replaced all of the windows in my North Aurora townhome as well as the rear exterior door. Even though I had done A LOT of research before Pat came out to provide the bid, I can't say enough about how thorough and patient he was in explaining the installation process and the various features of the windows. After he left I knew if the price was reasonably close to the other bids I wanted to work with Premier. The installation crew was also professional, courteous, and competent, and they worked efficiently to get the job done."

"Excellent price. Great job installing windows. Customer service very helpful. Had all windows replaced. Windows made in Illinois. Made a significant improvement on my heating bill."

"Karl was fantastic. He did a great job educating me about windows. He kept in touch with us and let us know where the windows were in production and when we could expect installation to begin. The installation crew was phenomenal. They were professional and very efficient. I would highly recommend Chicago Window Wizards!"

"Excellent work on windows that had a rotted out frame! Very happy with the results!"

"It went very well Gus explained everything from process, how long it would take and pricing. Once the windows arrived they did the job in 1 day very quickly. Love the new windows and for sure I will call again to complete another project in our home. Great work done. From: Leo & Rosy"

"Very efficient! Came on time. Returned with finished cover as promised. Great advice as to maintaining upkeep of window as also the well. Thank you!"

"We used Integrity Windows and Siding back in 2012 to replace our siding and half of our windows (one of the windows did break shortly after installation - it was quickly replaced at no cost, no questions asked). Fast forward to 2023, we again sought out Integrity and Howard to install some of the remaining windows. Howard is very knowledgeable, easy to work with, explains options, kept us informed during the process and sells a quality window at a fair price. Mike, who has been with Integrity for 20+ years, was very careful during the installation - clearly he knows what he is doing! The windows look great, work great and keep us warmer. We highly recommend Integrity and Howard for your next project. We couldn't be happier."

"Closed stuck windows. Now OK as long as these windows are not opened. Offered service to replace hardware on window for $150 per window. Decided not to do anything."

"Professional and courteous installation team. The work was completed on the date specified in a timely manner. Windows look great. Excellent experience! Thanks for your help Steve!"
