Keystone Overhead Door has been serving the area with sales and service of both residential and commercial doors for 30 years. Keystone was originally founded in Pennsylvania, purchased, moved, and reincorporated in the Elkton Area over 32 years ago. Originally founded as a manufacturer of Fiberglass overhead door, the company has evolved throughout the years and due to increased costs has phased out the manufacturing process. We currently stock, distribute, and install products from six manufacturers. We feel that we stock the largest, most complete, assortment of sizes, qualities, and price levels in doors in the area. If there is a door that you have chosen that we do not have in stock, typically we can get it within a few short weeks.
