With 16+ years of experience in the windows replacement business in Ottawa, we work with homeowners, commercial clients, contractors and DIYers on projects ranging from heritage houses to custom builds.
Every window is custom made for your home, with a timeless design serving a lifetime.
We do it right, once and for all.
Quality Full-Frame Custom Window Replacement
When replacing home windows, our clients usually choose to upgrade the type of window to a new, more energy efficient one. But what if your windows could do even more for you?
At Buildmart, we look at your home and recommend if a different window would be a better fit — for example, replacing a sliding window with an awning window will let in more light and give you a better view. An awning window removes the frame in the middle while maintaining the same ventilating capacity.
New Home Windows in Your Style
We work with you to select the type and style of your new custom windows. Together with our team, we choose the best exterior, interior, and hardware finishes for your new windows so they will last you a lifetime.
You have a choice of material, style, and finish for your new windows, pick from:
- Fibreglass
- Wood
- Aluminum
- Vinyl or
- Clad wood window frame
When replacing windows, choose the same style of window, whether casement, single or double-hung, sliding, picture, bow and bay, or awning windows. Alternatively, we will make a recommendation on a new style!
A good example would be the project below: here, to maintain the classic look, we made the recommendation to install windows with custom diamond grillz.
Our custom STAGE Windows, manufactured to your exact specifications for every single project, come in a big variety of colours. Painted to order, these window replacement units are available in a stock of more than 12 exterior colours, such as cashmere, black, commercial brown, sandalwood and more.
Plus, take advantage of the interior colour matching program to get the perfect custom fit for your home, whether you are going for a minimalist modern aesthetic or a traditional heritage classic fit.
