Reviews for Replacement Window Company Windows of Wisconsin

Great team fro the salesman to the office to the installation team. Great group of professionals to work with.

We would recommend Matt Gonwa and Windows of Wisconsin to anyone looking to replace windows! Matt is knowledgeable and dedicated to customer satisfaction. The installation team was courteous, attentive to detail, and completely professional. The windows themselves are of excellent quality and easy to clean and maintain. A much better overall experience than we had with Pella!

We have used WOW for some previous work and when it came time to finish replacing the rest of the windows in the house we new who to call. From Marshall our salesmen to the installers and even the office staff keeping us informed we have been very satisfied and would not hesitate to recommend them to any one.

Very professional and good price/value. They kept us informed during the process. The installers were courteous and meticulous. They wanted everything perfect which is how it turned out. Would definitely recommend.

What a great experience for a major home purchase! From the first meeting with the sales person Tom through the installation and inspection the WoW team made sure we were happy with the product and installation. We were perhaps the first customer to ask for black sills and there were some issues matching the touch up paint sheen. They went back to the shop to work on a solution to the problem and then sent their top notch installers to work through the problem at our house and gave us options to ensure we were happy with the results. Corey and Sean did a great job as well as the rest of the team! It's difficult to find a company out there that works tirelessly to make sure the customer experience is second to none, but Windows of Wisconsin definitely falls into this category!

Was an excellent install as promised, worked with my schedule and did very good quality work. Always on time and would highly recommend them for your window replacement needs.

We are replacing the cheap windows that were installed in our house when it was built 11 years ago. We met with Thom Kohlbeck last fall to discuss our window project. Thom was very informative and answered all of our questions and got us pricing on replacement windows for the whole house. Absolutely NO high pressure!! Which was very refreshing after the experience we had two other window suppliers. We decided to split the project in 2 phases. So we had the sliding patio door and the 5 windows on the front of the house done on 4/10, and we will do the rest of the 12 windows in 2024. The crew at WOW followed the exact process that Thom said they would. We supplied them with a piece of window mounding and they supplied us a sample to show the color match. As promised, the installation date was set up after they received the windows. Our installation crew consisted of Kris, Jeremia & Adam. What a great group of guys to work with! We explained our concerns about being able to use our window blinds with the new windows and they said they would take care it. They covered the floors and removed our blinds. They took great care when they removed the old windows, keeping all the “mess” outside. It was fun watching them work. Very meticulous. They taped each opening, leveled windows, foam insulated inside and out, cased and jammed each window and even rehung our blinds! After they cleaned up, they showed us how the windows operated. We immediately noticed how much quieter it was in the front of the house. We’re anxious to see how they perform this winter. If all goes according to plan, we will have the rest of the windows replaced in 2024. When doing a project involving a significant amount of $$’s it can be a big concern. So far, It’s been a very good experience.

We had all of the windows and 2 sliding doors replaced in our built-in-1986 home with Infinity by Marvin products. The windows/doors are beautiful and so much easier to use than our old ones. Alex H’s crew was extremely professional and hard working: they were short-handed for a couple of days (who isn’t short-handed these days?) and still managed to get through everything during the original estimated timeframe. Alex made sure I was informed and brought decisions to me in a clear and concise manner. Everything looks great, thank you Alex and team! The sales experience was so much better than the experience we had with Pella: Marshall walked us through our options, made recommendations, and answered our questions—just the kind of no pressure, no gimmicks experience I expect from a great Midwestern company. The communication of the scheduling of our installation could have been better, but the overall experience is still worthy of 5 stars!

Special thanks to Marshall and Chris' installation crew!
