Plan on about 0 to ,500 per installed window in Quebec in 2026, or ,000 to ,000 for a 10-window house, before Rénoclimat.3 Published ranges run wider, from about 0 to ,500 a window, because they mix retrofit and full-frame jobs, vinyl and aluminum, and different cities.479 Rénoclimat then returns 0 per eligible opening, up to ,500 for a house.1 These are market ranges, not Factory Direct prices. Your price comes from a written quote after an in-home estimate.
Installed price per window, Quebec market ranges 2026
How much does window replacement cost in Montreal?
We found no Montreal-only price published in 2026. The best data is Quebec and Canada market ranges, each with a date. We show every range and the gaps between them, so you can see the spread.
The Quebec guide updated in April 2026 says a standard 24 by 48 inch window costs $800 to $1,500 installed.3 A national cost guide from RenoQuotes, also updated in April 2026, prints the same figures.6 Other pages sit lower. HomeStars (August 2026) puts a standard replacement at $300 to $1,000.7
| Window style | Quebec guide, Apr 20263 | Quebec guide, Jan 20264 | HomeStars, Aug 20267 | Canadian Choice, May 20268 |
|---|---|---|---|---|
| Casement | $950 – $1,400 | $350 – $1,200 | $450 – $900 | $700 – $1,100 |
| Awning | $900 – $1,300 | $400 – $1,000 | $400 – $850 | $700 – $1,100 |
| Sliding | $650 – $950 | $800 – $1,000 | $350 – $750 | $700 – $1,100 |
| Single or double hung | $750 – $1,100 | $200 – $1,100 | $300 – $800 | $700 – $1,100 |
| Picture (fixed) | Not listed | $300 – $1,300 | Not listed | $500 – $1,500 |
The pages do not agree on what a price includes. Some cover a retrofit in the old frame, others a full unit. That is why one casement window shows $350 in one table and $950 in another. Always ask what a number includes.
Vinyl, hybrid or aluminum: how much does each frame cost?
Vinyl (also called PVC or uPVC) is the lowest-priced frame, according to SoumissionRénovation.4 Its PVC page (March 2026) lists PVC casement windows at $300 to $1,100 and awning windows at $400 to $800.5 Hybrid has a PVC core with an aluminum shell outside. It suits dark or coloured exteriors.11 Aluminum costs the most in the Quebec guide and the least in the Ontario one.
| Frame | Quebec guide, Apr 20263 | Canadian Choice, May 20268 | Magic Window, Jun 2026 (Ontario examples)9 |
|---|---|---|---|
| Vinyl (PVC) | $800 – $1,100 | $700 – $1,100 | $450 – $950 |
| Hybrid (PVC + aluminum) | $1,100 – $1,400 | Not listed | Not listed |
| Aluminum | $1,300 – $1,800 | $600 – $1,500 | $400 – $850 |
HomeStars lists the frame and sash alone, without labour. Vinyl runs $150 to $400 and aluminum $200 to $500 for the unit.7 Labour, glass and trim come on top.
How much does a whole house cost?
Multiply by your number of openings, then add the extras below. Count every window, basement window and patio door that gets replaced.
| Home | Windows | Range (CAD) | Source |
|---|---|---|---|
| Small bungalow | 6 to 8 | $7,500 – $11,000 | Quebec guide, Apr 20263 |
| Average detached house | 10 to 12 | $12,000 – $18,500 | Quebec guide, Apr 20263 |
| Large home or chalet | 15 or more | $22,000 and up | Quebec guide, Apr 20263 |
| 3-bedroom home | 20 to 29 | $10,000 – $29,000 | Canadian Choice, May 20268 |
| 10 standard vinyl windows, Toronto area | 10 | $8,000 – $15,000 | Magic Window, Jun 20269 |
The spread is wide for a reason. Window count, size, shape and frame type move the total more than any other factor.
Does triple glazing cost more than double?
Yes, but the gap is smaller than most people expect. HomeStars puts triple glazing at $100 to $300 more per window than double.7 Magic Window, whose examples are Ontario homes, says $150 to $300 more.9 Two sources, two dates, almost the same gap.
Factory Direct windows come with double or triple Low-E glass and argon gas.11 Ask for both prices on your quote. Then you see exactly what the extra pane costs your house.
What are the extra costs: installation, brick-mould, capping and disposal?
Check each of these on every quote. They explain most of the price gap between companies.
- Installation labour. Quebec and Canadian sources give $150 to $350 or $150 to $400 per window.38 HomeStars shows $100 to $300 on the ground floor.7 Magic Window shows $70 to $150 for labour alone.9
- Full-frame or retrofit. Full-frame removes the old frame and trim. The Quebec guide says it adds $400 to $600 a window.3 HomeStars says $100 to $200.7 Magic Window prices retrofit at $350 to $900 and full-frame at $600 to $1,500.9
- Brick-mould. This is the outer trim on a brick home. Some frames include it. Factory Direct lists a casement and awning frame at 4 9/16 in, or 5 3/4 in with brick-mould.11
- Aluminum capping. Capping covers old wood trim instead of replacing it. One Ontario contractor lists $9 per linear foot, with a $900 minimum, checked in October 2026.10 That price is not for Quebec. It shows the order of size.
- Removal and disposal. No source gives a separate dollar figure. Canadian Choice says installed prices usually include removing and disposing of the old windows.8 Magic Window says to ask.9
- Taxes. Some contractors quote before tax.10 Ask which one you are reading.
What do plexes and brick homes add in Montreal?
Plexes and brick homes are common in Montreal, and they change the quote in four ways.
- Upper floors. HomeStars adds $200 to $500 per level for scaffolding or a lift.7 A three-storey plex pays that on every upper level.
- Odd openings. Old brick openings are rarely square. HomeStars lists $150 to $400 per opening for framing adjustments.7
- Trim. Decide on new brick-mould or capping before you compare prices. Otherwise one quote includes it and another does not.
- The Rénoclimat cap. A duplex, triplex or multi-unit building can claim up to $6,000, not $4,500.1
How much does Rénoclimat give back on windows?
Since October 1, 2026, a new file earns $300 per eligible window opening. The cap is $4,500 for a house and $6,000 for a duplex, triplex or multi-unit building.1 You need ENERGY STAR Most Efficient units, an RBQ-licensed contractor and the signed conformity form.12 The energy evaluation before the work is now optional.1
Some pages still show $150 per opening, including Québec.ca for files under the old rules.23 Confirm the amount on Québec.ca the day you sign.
| Your home | Openings | Rénoclimat aid | Why |
|---|---|---|---|
| House | 8 | $2,400 | 8 x $300 |
| House | 10 | $3,000 | 10 x $300 |
| House | 15 | $4,500 | Reaches the house cap |
| House | 20 | $4,500 | Capped at $4,500 |
| Triplex | 20 | $6,000 | 20 x $300 reaches the $6,000 cap |
Worked example (made-up quote, not a Factory Direct price). Say a written quote for 10 Most Efficient windows is $14,000. Rénoclimat returns $3,000. Your net cost is $11,000. In a triplex, a $28,000 quote for 20 openings returns $6,000 and nets $22,000.
Three tips. Several windows in one opening count once, so a bay made of three windows in one rough opening is one opening.2 Replacing only the glass or the sash does not qualify.2 Apply online within 12 months after the work ends.12 Our Rénoclimat windows and doors checklist walks through each step.
When is the best time to buy windows?
Late spring to early fall is peak season. Demand brings longer waits and higher prices.13 Winter has fewer orders, so service can be quicker.13 Below -25 °C, installers need special foam.13 Read our guide to the best season for window replacement before you book.
How do I compare window quotes?
Ask every company to price the same job. Use this list.
- Same number of openings, same sizes, same styles.
- Frame type: vinyl, hybrid or aluminum.
- Glass: double or triple, Low-E, argon.
- Which units are ENERGY STAR Most Efficient, marked on the quote.
- Full-frame or retrofit, and what trim is included.
- Removal and disposal included or not.
- Taxes included or not.
- The RBQ licence number. Check it in the RBQ licence registry.14
