Question 1

How much does it cost to replace windows in Canada?

Accepted Answer

Windows Canada's 2026 guide puts standard replacement windows at $500–$1,200 per window installed, so replacing 10 mid-grade windows typically lands near $8,500 before tax — small vinyl jobs fall lower while bay, bow, and triple-pane upgrades run well above. Use the calculator above for a range matched to your window count, size, and material.

Question 2

What's the difference between insert and full-frame replacement?

Accepted Answer

An insert (retrofit) window fits inside the existing frame and is faster and cheaper. Full-frame replacement strips the old frame down to the rough opening, adding removal and trim labour, and is the right choice when the existing frame is rotted or you're changing the window size. Toggle 'Full-frame replacement' to include that extra labour.

Question 3

Which frame and glazing should I choose for a Canadian climate?

Accepted Answer

Vinyl with double-pane low-E glass is the budget standard; fiberglass and composite frames are the durable mid-grade; wood-clad frames with triple-pane glass sit at the top and are popular in cold provinces for their insulation and condensation control. Pick the option that matches your climate and budget — the calculator scales the estimate accordingly. Prices shown are before GST/PST/HST, which is added per-province at billing.
