Windows of Wisconsin

Windows of Wisconsin installed Marvin Infinity replacement windows in our home about 10 months ago, and they have been a significant improvement over the inexpensive windows previously installed. Choosing Windows of Wisconsin was an easy decision. Marshall and the sales process were fantastic. He was honest with his assessment of the current condition of our windows and did not take part in high pressure sales tactics like other big-name organizations we quoted. They worked with us on style and design. Additionally, we had to replace all interior jams/trim around the windows, which they color-matched perfectly, and made the new windows look great. The team demonstrated great integrity throughout the final inspection process, calling out a couple of items they needed to come back and fix. Although it took some time after the job to complete the follow-up work, all pending fixes were...

I'm very happy with the quality of my windows! Working with WOW went smoothly from start to finish. The installers were polite, professional, and did an awesome job!!! I highly recommend them. J. Hecker

Recently we had new windows installed along with the wrapping of some existing windows. After a lot of research and comparing other products, we made the right decision by choosing Windows of Wisconsin. With the helpful assistance from Thom Kohlbeck, the sales representative, we selected the Infinity Line by Marvin Windows. The installers; Leonard, Alex, Jonah and their supervisor Ryan were very professional, prompt and respectful. They answered our questions, paid attention to details, and cleaned up the work site upon completion. We highly recommend Marvin Windows and the Windows of Wisconsin Company.

The sales rep, thom Kohlbeck, was very good at explaining the workmanship of the windows and the installation process. We wanted some tinted windows and he was able to get us some samples the next day after our appointment. The installation crew, Dustin, Leonard and Jonah were very good also. They were very respectful of our personal space throughout the installation and cleaned up at the end of the work day. They were very quiet and worked well together. We were very impressed at the detail in taking out the old and putting in the new windows. I would refer Windows of Wisconsin to anyone looking to replace their windows.

Excellent experience from start to finish.

Salesman was easy to talk to. Office staff was great with communication throughout the project. Installer did their job perfectly and left almost no trace they were there.

Extra credit for the final walk through with the saleman again, who spotted a few very minor issues that I likely never would have noticed. All of which were resolved quickly and easily.

I don't expect to need windows again in this house in the near future, but if the need arises, I'll start with Windows of Wisconsin.

WOW did a great job for us. From start to finish. We did complete house and the new windows look great. All the details were professionally handled. Completed the project on time. Love the windows, look great and friendly people.

We had Infinity windows installed by Windows of Wisconsin and we are extremely happy with the results. The sales rep was great to work with along with the installation crew. Great windows, great service, and look for our home. The price was very reasonable considering the quality of window product we received. We would recommend Windows of Wisconsin to anyone wanting great windows for your home.
Thank You.

The work they did was excellent but the communication lacked, but they made it good! Might call them for a couple more!

If you're looking for windows, call Windows Of Wisconsin! WOW, WOW, WOW... they are amazing. They replaced five of our upstairs windows on the hottest, muggiest day of the year. Our home is over 100 years old and very hard to cool the upper floor. They powered through the heat and did an outstanding job working with nothing that is square. Big THANK YOU to Tyler (the Sales Manager), Leonard, Glen, and Sean (the crew), and Casey (the production manager) for a job well done. Everything was positive from start to finish and we are beyond happy!

Great service and great price.

All employees of Windows of Wisconsin are skilled, respectful, know their product. Very pleased with everything.

They are hard-working people never stopped and talked. Maybe a little bit. They kept right on going. They did a very good job. We thank you so much. We appreciate your business. Thank you. Have a good day.

Best customer service ever! Honest company, knowledgeable employees, A+ product.

Excellent service, beautiful window and good price

I like their windows and how the wood was stained to match the other wood in the room. The workers did a great professional job installing the windows and put back the house’s sidings very well. I had a very slight concern about the way a few screens didn’t seem to be attached very securely. I called Windows of Wisconsin, and they came back and made the screens very secure - at no cost to me. Just the way it should be! They also offered us a way to pay for the windows and installation with payments with no interest.

Great workers very professional and I could tell they knew what they were doing by how efficient they were working!

Amazing products, and an amazing place to work!

Great service from start to finish.

Friendly very neat love the windows

The windows are perfect and the stain on the trim match perfect with the other stain in the room. The cleanup after the windows were installed was very good. I would recommend a friend in purchasing theses windows.

Professional. The price they quoted was the same after the windows were installed. The staff all completed the job in the time they quoted me. They cleaned everything up well. They showed me how the windows functioned. They encouraged me to call if there were any problems. I would recommend them to others. If I have other windows done, I would call them

Prompt service. Great pricing and they always make sure the job is done right.

I love the patio door put in by windows if Wisconsin
The workmanship was excellent and the window is beautiful

Every aspect of replacing a decrepit old patio door went smoothly, from choosing the replacement to installation. It not only works beautifully, it looks beautiful.

Made the process very easy for us and the financing was a key part along with a superior product

From sales to installation to final inspection the experience with Windows of Wisconsin was superb. We did color match and it’s perfect. Sales was informative and not pushy. Installers were efficient, conscious of our home/belongings. They listened to my questions and spotted issues before I did.
Final walk through was a snap since all the staff before that point did their jobs effectively. Highly recommend!
Bonus is the window efficiency and ease of cleaning. I love them.

It has been a year now since I ordered windows from Windows of Wisconsin and I am as happy as I was when I got them. I checked out many companies and I definitely chose the best.
They have the best customer service ever. My windows are perfect and I can't believe how well they match my woodwork. I had friends that got new windows around the same time I did but they went with a different company and they were not happy and I am sure they wish they would have gone with Windows of Wis.. I am older and somewhat handicapped so I can't thank them enough for being so great. They are so easy to work and I can now wash my windows myself.
Thank you so much Windows of Wisconsin

Custom windows look fantastic. They service after the sale. Will order more to finish the whole house. Highly recommend!

In Aug 2024 my 55-year old windows were replaced with Marvin Infinity. They look and work great. It used to take a weekend to wash windows and now I do them all in few hours. Thanks Matt and the crew!

Had a very smooth experience. Matt G was great to work with, the installation crew was very professional and got the work done on time, and the windows work great!
