Gem Windows & Doors.  A better outlook on life

Toronto’s oldest and most trusted windows and door company

GEM Windows & Doors was founded more than four decades ago by the Christopoulos family. Today we’re still a family-owned and operated business located in Toronto. Over the years, materials and technology have changed, but our hard-earned reputation for quality products, installation and service have remained constant. GEM was among the first to participate in Window Wise, a quality assurance and energy efficiency certification program that gives our Toronto-area customers confidence and peace of mind. Customers love our competitive pricing and price match guarantee, too. If you’re looking for a Toronto-area windows and door company that will provide cutting-edge products and installation with an old-fashioned work ethic, look no further than GEM Windows & Doors. Whether you’re located in Scarborough, Don Mills, North York, Downsview, East York, Willowdale or York Mills, we’re only a click away…or drop by our 5,500 square foot showroom in Etobicoke. You will find some of the best replacement vinyl windows and doors on the market, along with wood and steel doors and windows. GEM Windows & Doors
