We offer turnkey supply of commercial door frames, doors, and door hardware for medical, educational, community redevelopment, hospitality, military, public and private projects. Commercial Installers was founded in 1989 by Robert M. Mitchell. The company started out modestly with only two carpenters. They began subcontracting installation of doors and door hardware from several local general contractors on commercial construction projects. After only a short time, the reputation of Mr. Mitchell, as a craftsman with uncompromising attention to quality and as a business man with integrity and honesty, became well known.
