On average, replacing a standard vinyl window in Ottawa costs between $600 and $1,200 per window, fully installed. Larger or custom windows, such as bay or bow windows, can range from $1,200 to over $2,500.
For a typical Ottawa home requiring 10 to 15 windows, a full replacement project generally costs between $9,000 and $18,000. This depends heavily on the window styles, glass efficiency, and installation method.
Yes, a full-frame installation, which involves removing the old frame down to the studs, typically costs 15% to 20% more than a retrofit installation where the new window is inserted into the existing frame.
Triple-pane windows usually add 15% to 20% to the upfront cost (roughly $100 to $200 more per window) but are highly recommended for Ottawa's harsh winters, as they can significantly reduce heat loss and lower annual energy bills.
