WindowsPicture WindowsExpansive Views, Effortless Style

Picture windows are fixed, non-opening designs that frame the outdoors like a work of art, offering wide, unobstructed views and abundant natural light. Ideal for spaces where open windows might interfere with decks, walkways, or landscaping, they enhance both beauty and brightness in any room. Highly energy-efficient, they can stand alone as a dramatic focal point, be grouped for a panoramic effect, or paired with operable styles like casements or double hung windows to add ventilation.

Choose from decorative or stained glass, privacy or tinted panes, and interior grids to create a look that fits your style.

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!
