A personal  message from Millennium Windows & Sunrooms

Thank you for taking the time to find out about Millennium Windows & Sunrooms. You’re here because you are interested in improving your home and lifestyle with a new sunroom addition and to find out your options, then make an educated decision on your sunroom contractor.

After all, you are taking a huge step and making a considerable investment of your personal finances, regardless of whether you pay by cash, credit card, or opt for our great financing plans.

Every company brags about how they are the “trusted sunroom builder” in Milwaukee. Easy to say, harder to live up to that standard. We understand there are many contractors throughout Southeastern Wisconsin, and it’s our dedication to satisfied customers, earning your testimonials and referrals that drives our business. We enjoy the look on your face when your sunroom is completed. It’s a great experience.

My personal career in home improvements, sunroom and outdoor living spaces construction spans nearly three decades. Rest assured I’ve seen just about every configuration of a sunroom you can imagine. There is no “one size fits all” when it comes to adding on a basic sloped roof sunroom to a more elaborate gabled-roof, all season sunroom that becomes an extension of the home.

Your sunroom starts by building a relationship first.

Frankly, we don’t feel comfortable with being that “one stop closer” salesperson who comes into your home and won’t leave until you sign a contract. That’s when trouble starts and your sunroom project starts to experience problems.

We are happy to spend as much time as needed with you, discussing sunroom designs, building and budget options. We understand this process takes time. You have a lot to think about.

So, please call me with any questions you may have about building your new sunroom. We can set up an appointment at your convenience. If you prefer, you can use our online Request an Appointment Form.

Thanks again for visiting and hope to hear from you soon.

Please call us at 262-894-1431 for your free estimate and no-hassle consultation.

“After having four windows and three doors replaced by Millennium, we want to let people know what a wonderful job this company did, and how pleased we are with the work.  Not only are the windows beautiful, but they are very ergonomic (designed for maximum comfort, efficiency, safety, and ease of use).

They also seem to be energy efficient, reflecting the wind, cold and sun.The best part was the gentlemen that installed them.  Mark and Kyle were so friendly, and they did excellent work.  We really appreciated how polite and helpful they were – and hard working.

Thanks again for doing a great job.  We are absolutely thrilled with our new windows and doors.”
