Foothill Window Center

Foothill Window Center offers competitive pricing on some of the finest vinyl and aluminum windows and patio sliding doors available to the public.

Started 35 years ago in Upland, CA and previously operating under the name of Alwindor, MFG. and then S.L.I. Windows & Doors has been one of the leading contributors to the supply of energy efficiency dual pane aluminum and now vinyl windows and doors in new and used housing additions for some of the largest Southern California home builders.

Now homeowners and local contractors can benefit from decades of product innovation and professional customer service by experiencing Foothill Window Center and their broad line of replacement or new construction vinyl or aluminum windows.

Homeowners and contractors can purchase a unique brand of window, superior to most other brands, at pricing less than the major "big box" DIY stores.
