Since 1983, Winchester Industries has been a highly respected member of the replacement window and door industry. A privately-owned business, Winchester manufacturers the Bristol and Oxford windows and doors. Winchester maintains an exclusive dealer network of specialty window and door companies. This network covers states within the USA that are represented by exclusive territories. Sales representatives are knowledgeable, and installers are carefully trained to measure each home and precisely install these units. All products are custom-made for every opening, which ensures a perfect fit. We believe that homeowners should only replace their windows once. To achieve this, a superior product designed to perform and last their lifetime must be used. Winchester, its employees and dealers, take great pride in the American-made craftsmanship of the windows and doors. Homeowners who select our products join us in this well-deserved satisfaction. The foundation of Winchester was built when owners Robert Weis and George Yuhasz combined over thirty years of industry knowledge to debut the first triple-glass Bristol replacement double-hung. Making triple-pane windows nearly 4 decades ago set the stage for Winchester to be a leader in window innovation. The need for more energy efficient windows was apparent then and remains steadfast today as energy costs continue to escalate. The revolution of Winchester’s top-of-the-line windows has evolved from clear triple glass to triple glass with multiple energy efficient features and patented technologies. These features include our own proprietary gas mixture, specialized spacer system, and superior reflective coating materials in true triple-pane insulating glass units. Our Q-IV Locking System surpasses security features already on the market. Weis and Yuhasz continue to monitor aspects of the business as President, Michael Sugrue running the day-to-day operations. The majority of Winchester’s staff have 32+ years of service.
