In 1987, Lynn Foster started Foster Exteriors as a window, siding and roofing company in Dallas. Over the years, Foster Exteriors has received many manufacturers’ awards for creativity and workmanship. In 2007, after 20 successful years, Lynn made the decision to specialize in Energy Efficient Windows exclusively, thus becoming Foster Exteriors Window Company, while continuing to maintain his three principles of Quality Materials, Quality Workmanship and Reasonable Prices. Our customers tell us that they receive good value because we offer the best products and service for the price. We have assembled a cohesive team of expert installers and staff that will assist you at every phase of this process.
