Why Choose Millennium
Windows and Sunrooms?

Millennium Windows and Sunrooms offers the largest selection of sunrooms and patio enclosures in Southwest WI. We offer a design consultation with the owner to survey your home, take measurements, interview the client, discuss budget and review samples to be most informed and able to make an educated decision. You will be provided with a quote and a 3D rendering of your project. Pictured to the left is a 4 track window, our most popular option for conventional and modular sunrooms. These windows can completely fold so all four panels are together (top or bottom) so you have a screened room feel.
Based in Milwaukee, we are proud to be a BBB accredited business that has been impressing customers with our expert craftsmanship since 2000. Since the beginning, our top priorities have been integrity, quality of materials, and workmanship. These qualities have helped to build the foundation of a trusting relationship with each of our customers. We fully stand behind our work, and we think you will too.

How does the process work?

When you choose Millennium Windows and Sunrooms, you’ll get a full personalized experience, without any pushy sales tactics.

Once you reach out to us, we’ll schedule a no-pressure phone consultation to discuss all details and any questions we may have. We have found this phone consultation speeds up the process. During the meeting, we’ll gather your information, your preferences and budget.

After the phone consultation we will create a 3D rendering (CAD) of what your finished project will look like, along with an estimate.

We offer more choices and variations in our project than any other company in Southeastern Wisconsin - so we’re sure we’ll be able to fulfill the vision you have!
