"From beginning to end this was a complete good experience. John came out and showed us the window and explained the process. After doing my research I have found the windows he uses to be excellent quality. Ordered the windows, 12 weeks to the date they were installed. The install was done in half a day. They team was very clean, helpful and complete. They answered all my questions and even let me watch! We noticed a difference within hours of sealing up the windows how cool my second story remained with the Energy Efficient windows in. I cleaned all of them with an easy process of sliding the clips and opening them. What a dream window and only wished we had done this ten years earlier. The windows were 29 years old, solid wood and clad. From the outside you can hardly tell the difference. These were a great purchase, and we are looking forward to having the other 13 windows done with 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."

"Gus and his team at EcoChamp Windows & Siding are amazing! They were very professional, responsive, and installed high quality windows in our home at competitive pricing. I love my new windows and Gus’ suggestions really made a difference. My husband and I highly recommend this company!!!"

"From the initial contact through installation, this experience was wonderful. Price was ideal and the workmanship spot on. We even had them clean the window wells (YUCK) we live near farm land and have lots of bugs and critters..."

"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!"

"Showed up as scheduled. Quickly replaced the thermal pane in my window . Price was reasonable."

"Windows were done in one day. Crew cleaned up nicely. Windows look great."
