WindowsArchitectural WindowsDistinctive Shapes, Lasting Impression

Architectural windows bring unique character to your home, offering custom shapes and sizes that enhance curb appeal and serve as a striking design statement. They can stand alone as a bold focal point or pair beautifully with other window styles to frame a captivating outdoor view. Perfect above standard windows or as an accent to patio doors, these designs let in abundant natural light while complementing your home’s style. Energy efficiency, ventilation, and visibility vary depending on whether you choose fixed or operable configurations and your selected glass options.

Design Options to Match Your Style

Custom-shaped architectural windows offer a variety of options to enhance both beauty and functionality, including decorative or stained glass, privacy or tinted panes, and interior grids. Explore our window brands to discover the design features available to create a unique, personalized look for your home.

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 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!
