General Doors Corporation
General Doors Corp. has been manufacturing sectional overhead doors since 1947.
Originally, the product lines were entirely wood doors, but we added commercial steel doors in the 1970's and residential steel doors in the 1980's. The 1990's brought development of a network of distribution and sub-manufacturing facilities to serve the East and Northeast parts of the country. The current decade has brought a continued expansion of manufacturing and distribution space, and the development of wood and steel carriage style doors. We are one of the few door companies that still makes a full line of wood doors and that still manufactures our own track and hardware.
