Founded in 1963, Stewart Overhead Door and Distributing has grown to become a leading supplier and installer of overhead garage doors in London and surrounding area. We carry a complete line of garage door products for residential, commercial and agricultural applications, including the Canadian-made Northland brand. In the almost 50 years that Stewart Overhead Door has been in operation, we have built a reputation for the quality of the parts we supply, for the skill of our installers and for the exceptional customer service that is at the core of our business philosophy. We collaborate with other organizations to share best practices and keep abreast of current technology through our memberships in the International Door Association (IDA) and the London and District Construction Association (LDCA). We have also been a BBB Accredited business since 1984.
