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.

We learned that the old windows were not even windows by today's standards, they were just huge panes of glass that gave no insulation. He measured the windows so quickly (like 2 minutes) that I wondered if the windows world 3 actually fit (they did!). The price was extremely reasonable; we had intended to get three estimates but my mom and I both lined Kris so much we decided to go with him right away. I chose a day for installation when Kris was going to be out of town on vacation so he let me decide if we wait to wait until he got back or if we wanted him to send his right hand man Daniel. We went with Daniel who showed up right on time on a cold morning. I thought removing the old badly cracked panes of glass would be very difficult. I was right but they got the old ones out quickly and the new ones in so fast and they finished about 30 minutes before their estimate. They only removed one window at a time and our house never got cold on a 33 degree day This was one of the best customer experiences for a project I have ever had. I chose EV Windows after asking CharGBT to find me a great window company with very good reviews and I'm so glad I did. I do not have one negative thing to say. I most strongly recommend Kris and his team.

He walked me through every step, set clear expectations, and was always quick to respond to my questions.

Their care and attention to detail stood out. They were incredibly respectful of the surrounding furniture, walls, and floors, and the cleanup was so thorough that the only sign they had been there were the beautiful new windows.

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!

However, I had recently moved into my new home and knew I needed to get these items updated before winter hit- especially the sliding door. All these items were the original windows and door from when the house was built. After researching and seeing the outstanding reviews for Opal, I decided to give them a call. I shared with Jose, the onsite project consultant, my prior experience and he made sure from start to finish I was informed and comfortable. I couldn't have asked for best customer service or transparency. Once I made the decision to move forward, Opal exceed every expectation from the ongoing communication breaking down the steps in my project timeline to the quick response from Katie with any questions. This company welcomes questions and offers ongoing support that's unbeatable. I strongly recommend you go with Opal Enterprises. I have never had such a stress-free home improvement project in my life! Trust me- you won't regret your decision to work with the wonderful team at Opal!
