    Casement Windows

    Taking pride in every Casement we build means beautiful design. With contemporary styles, Casements are hinged on the side so they vent vertically, allowing the smooth-turning handle to roll the window open and let in a summer breeze. The mechanics inside the Guaranteed Custom Casement were developed through years of experience to keep you comfortable, while allowing you to appreciate the custom design and your neighbourhood landscape.

    We’re dedicated to bringing beauty into your home, a mantra that led us to the charming and classic Double Hung window, with its clean interior appearance. Guaranteed Custom Double Hung are coil-balanced to open and close smoothly and both sashes tilt-in for easy cleaning. Use them individually for a look of understated elegance or pair several together for endless design combinations.

    Single Hung

    It’s the years of experience that we put into every Single Hung that makes the clean interior appearance so timeless. Guaranteed Custom Single Hung are triple-sealed to work against the elements and coil-balanced to open and close smoothly. The top sash is fixed while the bottom sash tilts-in for easy cleaning. Use them individually or join them together to accomplish your one-of-a-kind design vision.

    Bow

    It doesn’t feel like work when you do what you love. And we love crafting Bow windows. Commonly seen in a series of five, they sweep the outside of a wall, with windows that can be stationary, operating, or any combination. Guaranteed Custom Bows offer awe-inspiring views and create an enchanting dimension to your home. Take advantage of your Bow window with an elegant window seat, breakfast nook or plant ledge.

Our Doors


We offer 31 factory colours and "they're as individual as the people who purchase them".

I hired Guaranteed Windows and Doors to replace the 11 year old windows in my house when the price they quoted me was much more reasonable then the other companies. I do not regret my decision. Mario was great. They addressed all my concerns and questions without hesitation and professionally. Turns out the wood supporting my front window was a home for carpenter ants and Mario replaced the wood, insulation and drywall at no extra cost. I love my new windows!
