M & M Windows began in Scarborough in the house of two brothers on July 1, 1983 from which the company name is derived. Eric & Martin Mak, have brought not only knowledge, but skills and experience from Hong Kong thus creating the first “Chinese-operated window and door installation” company in Toronto.

They originally installed residential window and doors but have since expanded to commercial property and created new and distinctive designs. Aesthetic appeal of the dwellings & commercial units have been accentuated by their creativity and craftsmanship.
