Our Company

our clients come first


Our passion is to bring a great product selection to our customers. Not merely to sell, but to educate our customers of the choices available and to help them make the best choice for windows and doors in Montreal. To share our vision of honesty, integrity and loyalty with our team and our clients.


There is no better asset, or more valuable treasure than the people we work with. Our clients, our team and our associates are key factors of our success. With great pleasure, we recognize and acknowledge all who are loyal and true to our vision and our passion.


Having integrity means doing the right thing in a reliable way. To us it means following our moral and ethical convictions and doing the right thing in all circumstances. Reliability and steadiness of our service are part of our company’s integrity.


It’s a challenge to work in the service industry when you don’t absolutely love it. Every new addition to our team shares our founders’ love for providing a service that extends far beyond the sales or the installation process.
