Window and Door Replacement Costs in Canada

Style and glazing come first. A fixed or single-hung vinyl window is the budget option. Casements, awnings and tilt-and-turns cost more, and moving from double to triple glazing adds again. In most of Canada, triple glazing earns its premium on north-facing rooms and in colder provinces, but it is not automatically the right call everywhere.

The opening matters as much as the unit. A retrofit installation, where the new window fits inside the existing frame, is the cheaper job. A full-frame replacement, where everything comes out down to the rough opening, costs more but lets the installer deal with hidden rot and insulate the gap properly. On older homes, the retrofit saving can be false economy.

Then there is what the installer finds. Rotted sills, out-of-square openings and old aluminum frames with no thermal break all add labour. A quote given without anyone looking at your actual windows is a starting point, not a price.

Failed seals are the most common reason people call. Fogging between the panes means the sealed unit has failed, and on many windows the glass unit alone can be replaced for a fraction of a full window replacement. If the frames are sound, ask about glass-only replacement before accepting a whole-window quote.

Rotten wood frames, warped vinyl, persistent drafts and windows that no longer operate are replacement territory. So is the bigger-picture decision: if the windows are original to a 1970s home, the energy loss usually justifies replacement even when the units still technically work.

Window companies quote per opening but configure differently. One quote is a mid-range casement with triple glazing, full-frame install and new interior trim. Another is a retrofit double-pane unit at a lower number. Neither is dishonest, but only one comparison is meaningful.

Federal and provincial energy-efficiency programs have offered meaningful rebates on qualifying window replacements, and the programs change often. The quote you receive will almost always be pre-rebate, so check what your province and utility currently offer before you decide on scope. Qualifying usually means specific efficiency ratings, which is another reason to get the ratings in writing.

Published national data puts a standard exterior door replacement at roughly $1,725 to $3,288 installed. The same rules apply as windows: the slab is the cheap part, and the price moves with the frame condition, sidelights, the lockset grade and whether the opening needs work. A steel entry door is the budget choice; fibreglass and wood cost more and wear differently in Canadian winters.
