WindowsBay & Bow WindowsArchitectural Elegance with Panoramic Views

Bay and bow windows add striking dimension to your home’s exterior while creating a bright, inviting space inside. Bay windows feature three sections. A larger center window framed by narrower angled side windows. Bow windows use four or more equal-sized panes to form a graceful, curved projection. Both styles can be crafted with fixed, double hung, or casement units, offering versatility in function and design. Perfect for living rooms or master suites, they often create a charming window seat. Ideal for reading, relaxing, or simply enjoying the view.

Custom Options to Enhance Your Home

Our bay and bow windows come with a variety of options to elevate both style and function, including color choices, decorative or stained glass, privacy or tinted panes, and interior grids. Explore our window brands to discover the design features available for creating a striking, personalized window replacement.

Forefront replaced all of the windows and front door of our O’Fallon, Missouri home. They replaced the arch windows in the great room and kitchen, which were out of style, with rectangles. This updated the entire look of the rooms. They are who we will use for our future remodeling projects.

Forefront Windows & Doors took the idea of what I wanted in my foyer and turned it into a reality. Thank you for completing our renovation with excellence. You’re the best St Charles County has to offer!

Forefront Windows & Doors completely renovated my 1950s ranch home from its original state to a classy shabby chic. They did a front door replacement and screen door replacement, and completed interior work. They kept the character of my St Charles home yet added personal touches that were my own character Forefront stayed within my budget despite unexpected hidden expenses. I get so many compliments. I HIGHLY recommend this company’s services.

Forefront is phenomenal! He installed a beautiful 8 foot sliding glass door to my back patio along with a man door on the back of my garage at my house in O’Fallon! He made the process very easy with his great communication and his quality workmanship! I highly recommend Forefront Windows & Doors for anyone who has a renovation project. I will be using him again when I get new windows and doors for the rest of my house!
