Our handcrafted bay, bow, and garden windows bring elegant design, abundant natural light, and fresh air to your living spaces. These windows are a perfect combination of beauty and functionality, making them an excellent choice for enhancing your home. For all your specialized home renovation needs in the Chicago area, you can trust The Window Source of Chicago to offer a wide range of customizable solutions tailored to suit your style and preferences.
Bay Windows
Bay windows are a stunning way to expand any room, creating a cozy nook or seating area where you can relax with a good book or a warm drink. These windows not only enhance the size and appearance of your interior space but also allow more natural light to flood in, adding charm and elegance to your home’s architectural design.
The design features large, oversized windows that extend outward from the exterior wall, offering a breathtaking panoramic view and an abundance of natural light. Typically, bay windows include a large center picture window flanked by two double-hung or casement windows on either side, all of which can be customized to your exact size and style preferences, making them a perfect addition to any home.


Bow Windows
Bow windows offer a graceful alternative to bay windows, featuring three to six identically sized windows that gently curve outward from the exterior wall to form a bow shape. Like bay windows, bow windows provide a stunning panoramic view, an abundance of natural light, and excellent airflow when opened.
At The Window Source of Chicago, we can customize your new bow windows with one or more ventilating casement window components, allowing you to enjoy a refreshing cross breeze and a beautiful, functional addition to your home.
Can a Picture Window Be Replaced with a Bay or Bow Window?
Absolutely! With minimal structural changes, you can transform your living space by upgrading a picture window to a stunning bay or bow window. Most existing picture windows, regardless of their size, can be replaced with our beautifully crafted bay or bow windows, adding depth, natural light, and architectural elegance to your home.
All of our windows are installed by skilled local professionals who ensure they seamlessly complement your home’s design, avoiding the look of an afterthought or addition. At The Window Source of Chicago, our expert craftspeople can install your new windows by integrating them with an existing overhang or using an aftermarket roof assembly.
Now is the perfect time to expand your living space and enhance your home with the timeless appeal of a bay or bow window.
