His work and products are higher quality than the other 3 quotes I received, and his price was higher, but I went with Mike because of his great reviews and his custom windows.

He's been in business for close to 30 years, guarantees his work, backs it with warranties, and cares about his customers and his reviews.

If you're looking for reliable service, top-quality products, and a team that truly cares about customer satisfaction, I highly recommend Ultimate View Windows. I couldn't be happier with the results!

He was also extremely transparent and communicated with me on delivery timeframe of custom doors and windows via visits, phone calls and text messages. Paul came out after my choice of doors and windows for final measurements. After a reasonable lead time for the doors and windows, Paul and Derek came out and started their work. They completed the job over two days. Both are true craftsmen. I was absent most of the time attending to errands and work. At the end of both days, my home was clean from the removal and installation of new doors and windows. I could not be any happier with my overall experience with Ultimate View Windows and highly recommend anyone considering them for home contract work.

Naperville Windows and Doors stuck out immediately to me with quick communication via email and phone, along with free in-person consultation. There were no gimmicks, no games, no pressure to purchase, and a full out the door price (no pun intended) with no additional fees that would come later. Other people I spoke with tried to put some pressure on me with timelines and costs, but I don't do business with places like that. Don and Sandy were great and easy to work with, timelines were exactly what they mentioned, and the day of install couldn't have gone more perfectly. Jereen came by and did an incredible job on the install, with beautiful trim finishing around the interior / exterior and sealing everything up beautifully. The work was also completed in about 5 hours which was very speedy and efficient. The pricing was right in our budget and extremely competitive with all other vendors we spoke with, but the level of customer service exceeded everyone else by far. We'll continue to do business with them for all of our door / window needs in the future, looking forward to working with them again! Best, Charlie

We had a great experience with Naperville Windows & Doors. One of our windows was blown off our…read morehouse by violent winds during a thunderstorm. We did our best to seal off the opening with thick plastic and tape until we could get the window replaced but knew that wouldn't last long. One company we called wanted over $500 just to nail plywood over the opening. In the meantime, we called two window companies to get estimates for the replacement. The first company spent very little time and was rather short with us. They offered nothing in the way of covering the opening for the 6-8 weeks it would take for the new window. Then we called Naperville Windows & Doors. Their representative came to our house and took time to listen to us and address our concerns. Shortly after receiving our estimate (which, by the way, was over $1000 lower than the first company for the same window), Don (who I believe is the owner) came out to get exact measurements. When he saw the gaping hole in our house & our makeshift repair, he offered to nail the old window into place and seal the opening so we wouldn't be without a window for 2 months. When we tried to pay him for his trouble, he wouldn't take any money. Very impressive customer service! Needless to say, we chose to go with NWD. When our window came in, Joe came to install it. He was super nice & did a fantastic job! The window is beautiful & very solid. We were very happy with our experience with NWD and would whole-heartedly recommend them. In fact, we plan to begin replacing our other windows over the next few years & will go with NWD again when we do. Thanks again!

It took a few weeks for the two windows to be made, not unusual, and this past week he followed up made the appointment and finished the job. I have already referred Igor and Pro Windows to a few friends (whether they need windows or not) because he does a great job and why not share?
