Founded in 1975, Fenêtres MQ originally manufactured 19th century style furniture as well as traditional wood windows. The company quickly grew into a well-established manufacturer, combining a rare balance of craftsmanship and state-of-the-art equipment and precision. Fenêtres MQ has the unique ability to custom-engineer windows and doors to the most demanding criteria—virtually any size, operating style, shape, finish or combination, either in wood, wood-clad bronze or aluminum, steel and uPVC.

Your project

At Fenêtres MQ, we excel and thrive in true end-to-end partnership with architects, builders and owners of luxury residential and commercial projects. Each project is made to order, one at a time and individually supervised by a seasoned project concierge who attends to every detail.  That means that you can design fearlessly, build confidently and create extraordinary environments that are truly one of a kind.
