More than 50 years of the same quality, commitment and dedication are guaranteed to you with your purchase of Quaker Windows and doors. Founded in 1949 and based in Freeburg, Missouri, the Quaker family-owned corporation was manufactured on a business philosophy of quality and customer satisfaction that continues today.  Marge and Harold “Bud” Knoll dedicated themselves to building a business destined to be a leader in the vinyl replacement windows and door industry.

“A Tradition of Quality” has always been, and will continue to be, our motto and pledge. We constantly strive to build on our reputation for quality along with our history and passion for continual improvement and product development. Quaker’s second-generation owners are committed to making your new windows on the world the finest possible product available.

The AdvantEdge is a versatile window that is as practical as it is beautiful. Its design creates a clean, simple look and provides a maximized viewing area. Convenient features minimize maintenance, while a wide range of options allow you to customize the windows to match your décor.

When building your new home, the Brighton Series wood window is the logical choice. Brighton Series windows have an extruded aluminum-clad exterior, airtight glass and specially treated wood frames help you resist anything Mother Nature can throw at you.

The Vinyl Glide is one of the most modern doors on the market, literally years ahead of other sliding vinyl patio doors. A unique design sets the Vinyl Glide apart. When the operating sash is shut, it actually wraps around the main frame instead of closing into a jamb pocket. This elevates energy-efficiency, and minimizes any chance for water penetration.

The Vinyl Glide is made of the uppermost quality multi-chambered uPVC vinyl (pure vinyl), which ensures a long-lasting, beautiful look.

The Vinyl Glide has a solid structure. In addition to fusion welded corners, galvanized steel reinforcements are inserted in critical parts of the operating sash and meeting rail. (Other patio doors use aluminum.)

The frame is just as firm with fusion welded corners, and additional reinforcements inserted around the entire main frame to withstand heavy downpours and strong winds.

Installation time is decreased because the Vinyl Glide is set-up when shipped, thus minimizing the chance for installation errors.

All this structural integrity is combined with a smooth, easy operation and striking good looks you'll enjoy for years.

When building your new home, the Brighton Series wood window is the logical choice. Brighton Series windows have an extruded aluminum-clad exterior, airtight glass and specially treated wood frames help you resist anything Mother Nature can throw at you.

If you're remodeling, you can preserve the character of your home with Classic Fit historically correct wood windows. While duplicating the charm of your original windows, you also improve energy efficiency and performance. Because Classic Fit replacement windows are manufactured as a complete window, sealed and airtight, they look and perform better than any window replacement kit. These custom-sized replacements are easily inserted into your existing frame opening and can be stained or painted to match your existing design. With nothing to assemble and 1/4" increments for custom sizing, they install quickly and easily with no disturbance to the interior or exterior of your home. The exterior is aluminum clad, maintenance free and does not require painting. Classic Fit insulated glass and solid wood frames are energy saving and durable. Easy open tilt latches make for easy cleaning.

Patio doors are a critical design element - they welcome guests and help fill your home with light. With several designs and styles available, Quaker's wood clad patio doors allow you to make just the right opening statement.
