Great installation and very knowledgeable salesman ( Marshall)

W.O.W. called us almost 3-4 weeks ahead of the guesstimated installation date. Thom Kohlbeck - Salesman for W.O.W. represented the Company extremely well. His initial response/contact with us right from the beginning of Family room project was "customer service @ it's best. Response time was always "spot on" and the installation crew of Sean, Leonard, and Glen were professionally performed with the awareness of incoming weather. Attention to detail was appreciated by my wife & I.

I would highly recommend Windows of Wisconsin they did an awesome job. Everything from the sale to the install Matt and the installers were very knowledgeable and professional and explained things very well. THANK YOU Steve and Amy

We had our sunroom windows replaced with Windows of Wisconsin and it was a positive transformation of our space. The stain was a perfect match and our windows beautiful. The installing team with Corey and Sean were professional and no-nonsense. They installed the windows and door and left no trace when they finished. Thom was very helpful in helping us decide what we needed. It was the 2nd project he helped us on. We have installed our front windows and sunroom with WoW with no regrets and they are good to their word of making things right if there are any imperfections.

Josh came for a service call and happily tweaked our glass and front door, screen sliding door as well as our glass door locked. He check and rechecked that everything was in proper working order. Also showed/explained what he tweaked. In addition I had 3 window screens that had the beginnings of holes. He happily replaced them. I appreciated that he came on time, took off his shoes to go on the carpeted areas and that he was a happy person! TYSM Josh!

Professional job, excellent clean up. Very friendly workers. Highly recommend and would definitely use them again. Thank you!

Working with Windows of Wisconsin was an incredible experience from start to finish. The staff is not only friendly but highly skilled and got everything done in one day without leaving a trace behind. We are beyond happy with our new windows!

The window installers from Renewal by Andersen were very professional from beginning to end. They installed 11 windows in 1.5 days. They look very nice and we are happy with the results. Thank you so much Adam R. and Dylan H.

We are very satisfied with Windows Of Wisconsin and the work they did replacing windows and a patio door on our home. From the first step meeting with Matt, to the completion of their work, it was a good experience. We would recommend them for anyone's window needs.

I am more than satisfied with my experience with Windows of Wisconsin, from the beginning to the final installation. Everyone was very knowledgeable, professional, and friendly. I look forward to lower heating bills this winter. Thanks to everyone at Windows of Wisconsin.

Run, don't walk! What an amazing company to work with. From the very first phone call, WoW exhibited wonderful customer service, clear communication, met all of our expectations, and had exceptional follow through. If you're looking for a salesperson that is willing to understand exactly what you're looking for and offer you solutions to meet your budget and needs, Matt Gonwa is the person for you! Thank you for all of the time you took to work through our situation, Matt - we greatly appreciated all of your expertise!

We were extremely satisfied with Windows of Wisconsin. Patrick was a knowledgeable no-pressure salesman. The installers were very polite and efficient workers, and the office staff was very helpful in matching the color of the windows to our woodwork. We feel we received very high-quality windows for a competitive price and would recommend them very highly!

Great place to do business with and great product. There installer caught an issue with the sliding glass door and they reordered a brand new one for us. Love the windows!

Very professional, high quality, friendly experience on every level. I started shopping for windows 10 years prior to having any installed. (False start 10 years ago, lol.) I had everybody out for quotes…4 different vinyl companies, the overpriced composite ones, looked into other ones in showrooms. In my opinion, none of the others compared with the craftsmanship of these fiberglass marvin infinity windows through windows of wisconsin., The vinyl options out there were much lower priced, but to me I felt like I could tell why just by looking at and operating them. These fiberglass windows were a middle price point between the vinyls and composites at other companies. Over the years I kept my eye out for any other good options that might be less expensive, but I still came back to Windows of Wisconsin. Installed May 2024, the crew: Jordan, Shawn and Bruce, were very nice, meticulous, hard working. I enjoyed hearing them chat as it was clear they got along well as coworkers. Thom our sales guy was absolutely great as he endured my billion questions as we got all the plans and financing straightened out. And now we are enjoying out 17 new draft free windows .

Great group of people to work with from salesman to installers. All knowledgeable, efficient and thorough.
