Custom Windows Plus

Family owned & operated, Custom Windows Plus, LLC serves all of Wisconsin since 2007 by providing the best custom replacement windows & patio doors that stand up to the harshest weather, increase curb appeal, help insulate your home & save money on your energy bill, and stand the test of time! If you're looking for replacement windows, we supply and install bay windows, casement windows, awning windows, double hung windows, basement windows and slider windows. For your exterior door needs, we offer three types of patio doors: sliding patio doors, french patio doors, and terrace patio doors.

Being a family owned and operated business has its advantages, and most of them benefit our customers. Unlike big box stores, you're not transferred from department to department when you call us. We believe that personal service requires interaction between real people. That means we handle everything, from your initial inquiry to installation and future adjustments. As technology has advanced, the manufacturing of windows has changed in so many ways. Gone are the days of single pane glass and metal-framed windows built back in the '50's and only available in common sizes.

Our selection of replacement bay windows will enhance the appearance of your home. These beautiful windows are made using double window fusion-welded corners and can be custom fit to any opening for easy installation, reducing time and saving you money!

Available in 2-, 3-, and 4-panel designs, our sliding patio doors open up a new world of possibilities. Featuring steel bar reinforced vinyl sashes and a heavy-duty locking system, our patio doors are built to be as durable as they are attractive.

A double hung window is exactly like a single hung window, but you're able to open and clean both sashes instead of just the top one. Double hung windows are the new standard in new home construction and really make an impact on your energy savings. Beautifully crafted with fully-welded corners that keep your windows air & watertight and protected from stress. Your windows will open easily year after year.

If you prefer horizontal rather than vertical windows, slider windows are the answer! Slider windows are available in single, double, and triple sliders whose elegant, clean looks and efficient designs are quickly making them an industry standard. Beautifully crafted with fully welded corners that keep your windows air and watertight and protect them from stress, your windows will open easily year after year.

Whatever type of replacement window you need, Custom Windows Plus offers quality custom vinyl windows designed with energy-efficiency and durability in mind. Competitively priced, attractive & built to last, our vinyl replacement windows are a value-added investment to any home! Custom Windows Plus vinyl replacement windows are manufactured right here in the USA and backed by our Lifetime Limited Warranty. Built with maintenance-free u-PVC vinyl, our replacement windows offer amazing durability & resistance to the elements.

We have served many people in the Green Bay area over the years and we look forward to building new relationships in the future. As we all know, winters are quite cold here and that makes insulating your home extremely important. The same thing is true on hot summer days when you are running your air conditioning unit. Our vinyl windows help you achieve both! Vinyl windows can make a huge difference in your home's aesthetic factor and your energy efficiency will skyrocket and make your home more visually appealing!

Our french patio doors feature elegant solid brass hardware, aluminum-reinforced sashes, and steel-fortified frames. For convenience, each door comes with adjustable hinges for precise positioning during installation and future alignment. It's everything you need to make the design statement you want!

A nameless overseas company doesn't build our patio doors. They're proudly manufactured right here in the USA and backed by our Lifetime Limited Warranty. Fusion-welded corners ensure the structural integrity of each panel and maintain the strength of a dependably strong and durable frame. By using u-PVC vinyl, we eliminate the need for future maintenance chores (like painting, staining, etc.). Even the screen doors get special consideration! These are heavy-duty aluminum extruded screen doors featuring a no-rust fiberglass mesh.

Casement & Awning windows are uniquely designed to transfer the weight of the glass away from the open sash to the center of the window, providing long-lasting operation and energy-efficient seals!
