Windows of Wisconsin

We had four very high quality windws at a fair price installed this December 2024.
Couldn't ask for a better experience, from the 1st meeting Thom Kohlbeck and the crew. The install team were extremely professional, fast and efficient, and payed very close attention to every detail.
You just can't go wrong with this company.
I highly recommend Windows of Wisconsin.

We knew going in that we weren’t buying the cheapest windows out there, we got the Cadillac. Salesman Thom took the time to guide us through the options to help make 9 windows affordable. Much appreciated. Expert craftsman Sean,Glen and DE installed our windows perfectly. They were also neat and clean and answered my dumb questions. Whoever matched the wood color in the shop gets a thumbs up. Spot on! Needless to say we are very happy customers. Tell them Dean Wolf sent you.

Windows of Wisconsin was excellent! I worked with Thom in sales and Adam and Glenn on the install. The price was fair, Glen and Adam went above and beyond. They worked on our home as if it was theirs. I would hire them again in a minute.

Great job and very friendly and knowledgeable crew.

Great service from consulting with us to installation! Would definitely recommend!

I have been impressed from the salesman’s information, the installment, and the follow up after the installment.
I was sold on the quality of the patio door and the window I had replaced.
I am so pleased with the installed products. The installers were very professional and respectful of working in my home. The door and window matched my woodwork stain perfectly, and the installed window and door look awesome. The aluminum siding on the outside was wrapped perfectly.
In a heartbeat, I will call on Windows of Wisconsin for my next window and door projects.
I highly recommend Windows of Wisconsin to anyone looking for doors or windows.

Wonderful service from sales through installation. Great quality windows and so many options!We appreciated someone coming out right away when our window frame broke. The installers were wonderful- I would have never known they were here, except they left the area around the newly installed window in immaculate condition. Highly recommend!

We cannot say enough about our wonderful experience working with Windows of Wisconsin!!! From our initial meeting with Thom Kohlbeck and his explanations and guidance, to having the talented crews at our house working—I could not have hoped for more!!! The attention to detail, craftsmanship and courtesy was outstanding!!! The guys treated our house like their own—super respectful!!! I have so much confidence in the job they all did and that they stand by their work!!! I couldn’t recommend any company higher!!!
Thanks a million again to Thom, Ryan, Sean, Dustin, Shawn, Glen, Andy, Trey, Jonah, De and Leonard

Josh and Trey were amazing with the install!! Went smooth and very happy with the outcome 😁

We are impressed with the quality and price of the windows. The service was excellent, from both the sales representative and the installers. The warranty was difficult to beat. We have had the windows for 8 years, and they are still as good as new.

the install was excellant, installers were very polite and informative, the job was done in the estimated time frame. they demonstrated the new windows and how to use them and answered our questions. when they left everything was clean. we are very happy with the work they did and would recommend them to anyone

Windows of Wisconsin installed my patio doors. The installers were excellent. They were on time, very efficient, and cleaned up everything when they were finished.

The installation team was efficient and professional. The entire process from start to finish was great! Our windows look amazing!

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...

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.
