How pricing works
What goes into a window replacement price in Ottawa
Most of the cost of a replacement window is set by its size. This calculator prices each window at $95 per square foot installed, with a 10 sq ft minimum per window: a 24" × 24" bathroom window (4 sq ft) is billed as 10 sq ft, or $950.
The finishing work is priced by the window's perimeter. A typical Ottawa replacement includes a primed pine jamb extension, new interior casing, and aluminum capping outside at no extra cost. Upgrades such as triple-pane glass, exterior colours and grilles are added per square foot or as a percentage.

How is the online window estimate calculated?
Each window is priced by its area: width × height in inches, divided by 144, at $95 per square foot. Any window under 10 sq ft is billed as 10 sq ft, because small windows take the same labour and hardware as larger ones. Jamb, casing and exterior trim are priced per linear foot of window perimeter.
Does the estimate include installation?
Yes. Prices include a standard retrofit installation with removal of the old sash, insulation and sealing. Full-frame replacement, where the old frame comes out down to the rough opening, is shown as a separate option.
What is a jamb extension?
A jamb extension fills the depth of your wall between the new window frame and the drywall. Older and thicker walls need a deeper jamb. If you are not sure, measure from the window frame to the face of the drywall.
Is exterior capping included?
Yes. Aluminum capping, bent to wrap and seal the old exterior frame so it never needs painting, is included with every window at no extra cost.
How accurate is the online estimate?
It is a close starting point. Final pricing is confirmed after a free in-home measure, where the installer checks the openings, wall depth and any rot or framing repairs.
Is HST included?
No. Prices are shown before HST, and the summary adds 13% HST so you can see the full amount.
