Windows of Wisconsin

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...

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

Great experience from estimate to installation to quality of product. And half the cost of others. Highly recommend.

Pleased with the windows, install crew, and our sales rep Matt. Would recommend.
