Our family and dedicated staff have been installing and manufacturing custom quality windows & doors since 1985. Our passion and desire drive us to deliver windows & doors that you will be proud of.
In 1962, our father, Hermano Pereira immigrated from his native Portugal and found a job in a local wood window manufacturing plant located in Toronto. After a long successful career with one of Canada’s leading window manufacturers and establishing a love for the window & door business, Hermano opened up his own operation. Since that time, our family; along with our dedicated staff, have proudly provided specialized window and door installation services to thousands of residential and commercial customers in the Greater Toronto Area.
