## About

### Houzz Badges

- Star Houzzer
- 5 Ideabook Saves

With over twenty years serving the Toronto area, we understand the difference high-quality replacement windows or doors can make to the safety, security and energy efficiency of your Toronto house, and to the overall aesthetic and feeling that your home invokes. 

We’re meticulous in our choice of manufacturers and materials. Our manufacturers maintain the highest standard of design, construction and durability, and we work exclusively with Cardinal glass. Combined, these ensure windows and doors that are well-insulated for high thermal performance, built to last, and designed to suit your unique home.
 
High-performance, energy efficient vinyl windows and doors in Toronto are today’s standard, but we always raise the bar to remain first in glass. Our replacement windows and doors are built with glass from Cardinal, a tech-forward manufacturer that’s glass science obsessed. Through superior glass engineering and rigorous testing, they’ve developed layered glass that lasts longer, stays cleaner, and maximizes thermal performance.

 

The best replacement windows in Toronto are only matched by our knowledgeable door and window installers, who’ve designed, built and installed windows and doors replacements in over 30,000 homes across Toronto and the GTA to great customer satisfaction. We’re one of the few window companies in Toronto that trains and certifies our window and door installers through our own program to ensure the best possible service for you (though they're certified with the industry-standard WindowWise, too).
