Our Story

The Tale of two Brother

In 1987 brother’s Steve and Brian Mason, saw a need for exceptional quality windows in the Niagara Region. They had no investors, no experience only a vision of greatness. The next few years certainly came with its trials and tribulations, a less than stellar marketing plan and a few hundred window designs that didn’t make the cut. This only made us stronger and even more determined to get this right.

Almost 30 years later, we are incredibly proud to employ over 150 dedicated associates, self-manufacture, offer multiple products,  and service all of Ontario.

Our goal is simple really, we want to make and install the best windows possible, windows we would enjoy in our own homes.
