The initial consultation was very relaxed and no pressure. Jamie worked with us to use a mix of windows to get the price where we wanted and met us at the showroom to answer our questions and show us our options. It took a little time to get the color matching just right, but it was worth it. The installers were professional and detail-oriented and worked around my work-at-home schedule. Zach gave me options as the install was in progress and made sure that every window opened and closed smoothly. They answered my questions and were very efficient. I would definitely recommend Windows of Wisconsin

Patrick Richard, our salesman, was very helpful and thorough.

The price of the windows was reasonable, and they came a few weeks earlier than expected.

Our installation crew did an outstanding job. I know the installation took twice as long as anticipated (our house presented some technical challenges), but they didn't cut corners and rush the job. They were meticulous about making sure everything lined up as it should and looked perfect.

Beautiful windows. Great company - I've already recommended them several times to people in Door Co. looking to replace windows.
