Key takeaways
- Most window repair jobs in Canada land between CA$120–CA$1,200 — known locally as window repair.
- Window repair is generally unlicensed in Canada (Quebec's RBQ regime aside for contracted work). Freeze-thaw cycling makes seal failure common, so the IGU-swap trade is mature; matching low-E coatings and airspace matters for keeping thermal performance.
- Prices below are researched national ranges, updated July 2026 — not quotes.

What affects the price
- Job size and scope — bigger or more complex jobs move you up the ranges above.
- Access and condition — hard-to-reach areas, older properties or neglected maintenance add labour time.
- Materials and quality level — where materials are involved, the grade you choose often matters more than labour.
- Urgency — same-day or out-of-hours work usually carries a premium.
- Where you live — large metros in Canada typically run above the national range; smaller towns below it.
How to save
- Get at least three quotes and compare like-for-like scopes, not just totals.
- Be flexible on timing — off-peak slots are often cheaper.
- Bundle related tasks into one visit to spread call-out costs.
- Agree the scope in writing up front to avoid change-order surprises.
How to hire a window repair pro in Canada
- For fogged units, use a glass shop that measures and orders sealed units with the right airspace and low-E spec
- Ask about crank (casement operator) hardware experience — the classic Canadian repair
- Check insurance; repair work rarely needs licensing outside Quebec's RBQ framework
- Get warranty terms on new sealed units (aim for 5-10 years)
- Time non-urgent repairs outside deep winter — sealants and access are easier
- Bundle multiple windows into one visit for better per-window pricing
Red flags
- Recommends full replacement for a failed IGU in a sound frame
- No warranty on glass units
- Doesn't ask about low-E/argon spec when quoting a unit swap
- Cash-only with no invoice
- Sight-unseen fixed quotes

Frequently asked questions
What does a sash window overhaul include?
A full overhaul strips the sashes out, replaces cords/springs and beads, eases and adjusts, adds draught brush seals, and re-hangs. It transforms operation and draughts while keeping original glass and joinery — the standard treatment for period timber windows before anyone talks replacement.
Can misted (fogged) double glazing be fixed without replacing the window?
Yes — the sealed glass unit swaps out of the existing frame, restoring clarity and insulation for far less than a new window. 'Demisting' services that drill the unit are cheaper still but results are mixed and insulation isn't restored; most pros recommend a new sealed unit.
How quickly can a broken window pane be fixed?
Single-pane glass is usually same- or next-day: glaziers cut to size on the van or board up and return with the pane. Double-glazed sealed units are made to order — expect a temporary board-up or the cracked unit staying in place for one to two weeks until the replacement unit arrives.
How much does window repair cost?
Most window repairs are call-out jobs: hardware fixes (handles, hinges, locks, rollers) sit at the low end, replacing a failed double-glazed sealed unit sits mid-range, and structural frame or sash overhauls cost the most. Repair typically runs a quarter to half of replacement — get both numbers quoted when a window is marginal.
Why is my window stiff, dropping, or not closing properly?
Usually worn friction hinges, tired rollers on sliders, or a dropped sash catching the frame. These are standard parts a repairer replaces in under an hour. Ignoring a dropping casement eventually strains the frame and glass, turning a cheap fix into a big one.
Do window repairs come with a warranty?
Reputable repairers warranty parts and labour — typically 1-2 years on hardware and 5-10 years on new sealed glass units. Ask specifically, because warranty length on the sealed unit is a good proxy for the quality of unit they fit.
Is it worth repairing a window or should I replace it?
Repair wins when the frame is sound: misted glass units, broken hardware, draughts and stiff sashes are all fixable at a fraction of replacement cost. Replace when frames are rotten through, warped, or repairs recur — or when energy performance is the real goal and the windows are single-glazed anyway.
Why do sealed units fail so often in Canada?
Large temperature swings pump the glass panes daily, fatiguing edge seals until moisture gets in — so fogged units are routine after 15-25 years. Swapping the unit (not the window) restores performance if frames are sound.
