At Zen Windows, we’re changing the way people think about window replacements in Sun Prairie. We make the process simple and stress-free: no showroom appointments or in-home presentations that waste your time, no sales pressure or marketing gimmicks.

Windows That Work for Wisconsin Weather

Living in Sun Prairie means dealing with wide seasonal shifts. Your windows should look good and be able to perform year-round. That’s why every window we install is built to meet or exceed ENERGY STAR® standards. These windows are designed with features like Low-E glass coatings, multi-pane insulation, and argon gas fills to minimize heat transfer and reduce drafts. 

We’re strong advocates for energy-efficient windows in Sun Prairie because we know they give our customers a more comfortable home and lower monthly utility bills. According to the U.S. Department of Energy, homeowners can save up to $465 annually by replacing single-pane windows with ENERGY STAR®-rated models. In a climate like Sun Prairie’s, where both heating and cooling costs matter, that kind of efficiency pays for itself.

Why Sun Prairie Homeowners Choose Zen Windows

A Process that Puts You in Control

When searching for a window company in Sun Prairie, you’ll find plenty of options. But Zen Windows offers something they don’t: a process built around your comfort and convenience.

We believe that window replacement should be easy. When you work with Zen Windows, you get straightforward communication, high-quality products, and a team that respects your time and home.

Our process eliminates unnecessary steps and wasted time. Instead of scheduling in-home sales meetings, we give you a fast, accurate quote online. Selecting new windows happens on your own time with no pressure to make quick decisions. We’re here to offer advice and perform high-quality installations, not upsell. 

Local Expertise Homeowners Need

The right type of windows for a home can vary based on home architecture, window location, and other environmental factors. The replacement windows we offer are tailored to Wisconsin’s climate and designed to enhance your home’s performance and curb appeal.

You’ll work directly with a Zen Windows owner who knows your project and is always available to answer questions. You’ll never be passed from department to department.

A Real Lifetime Warranty

Our warranty covers both the windows and the installation, including window breakage. It’s also transferable if you sell your home, making it a real investment in your property’s future.

We fulfill warranty claims ourselves, so you never have to deal with an unknown third party. This allows us to respond quickly when you need your windows serviced. 

No Payment Until the Job is Done

We don’t believe in making you pay for services not rendered. You won’t pay a dime until your windows are installed and you’re fully satisfied. That’s how home improvement should work.

Replacement Window Shapes and Styles to Fit Any Home

We offer a wide range of window styles to match the unique needs of Sun Prairie homes, including custom shapes. Whether you’re updating a historic home or finishing a new build, we’ll help you find the right fit:

  • Double-Hung Windows: Versatile, easy to clean, and a great fit for nearly any room in your home.
  • Casement Windows: Hinged on the side and ideal for catching fresh air, especially in kitchens or upstairs bedrooms.
  • Sliding Windows: Sleek, space-saving, and great for modern homes or basement areas.
  • Bay and Bow Windows: Add visual interest and maximize natural light, perfect for living rooms and sitting areas.
  • Custom Shape Windows: Specialty shapes and styles designed to match unique architectural details and personal preferences.

All styles come in a range of colors and finishes to match or elevate your home’s aesthetic with ease.

Our Window Installation Process

We often get asked how long the process takes and what’s involved. With Zen Windows, it’s refreshingly straightforward. Our approach saves you time without sacrificing quality.

Trusted by Your Neighbors in Sun Prairie

We’ve helped hundreds of homeowners across Sun Prairie upgrade their windows, and the reviews speak for themselves. Whether you live in Wyndham Hills, Token Creek, or closer to downtown, we’ve likely completed a project right around the corner.

I’m really happy with the whole experience from beginning to end. What I was most impressed by was the great communication from the owner, Brad, who’s involved through every step of the way. I bought four windows and they really make the house look nice. Plus the warranty is the best I could find when I was getting other quotes. I would recommend Zen Windows to anyone shopping for new windows.

Choosing Zen Windows was one of the best decisions we’ve made throughout our entire home purchasing/renovation process. Their quote was by far the most affordable of the multiple places I called, as well as the lowest pressure/sales-y. Brad and his team are reliable, personable, and truly care about customer’s satisfaction. And most importantly, the window quality is incredible. Can’t recommend enough!
