Window Installation Costs in Canada 2026

Key Insights for Window Installation Costs

• Frame material: vinyl frames typically cost 20 to 30% less than wood or fibreglass for the same window size, making it the biggest cost lever most homeowners overlook.
• Labour share: installation labour accounts for roughly 30 to 50% of a typical quote, and that share rises on upper-floor or difficult-access windows where scaffolding or extra handling time is needed.
• Triple-pane value: the performance gap between double and triple glazing is most pronounced in provinces with long heating seasons, where the higher upfront cost is most likely to pay back over time.
• Bulk pricing: contractors often reduce the per-window rate on orders of five or more windows, with savings of 10 to 20% not uncommon on a full-house replacement compared to single-unit rates.

Average Window Installation Costs in Canada

The average cost to install windows in Canada runs from $300 to $1,000 per window for a standard replacement in an existing opening. That range covers most common residential sizes with a basic vinyl frame and double-pane glass. Costs move higher for larger windows, custom shapes, or openings that need structural modification before the new window can be fitted.

Window type	Typical installed cost per window
Single-hung, vinyl, standard size	$300 to $600
Double-hung, vinyl, standard size	$400 to $800
Casement window	$450 to $900
Sliding window	$350 to $750
Awning window	$400 to $850
Bay or bow window	$1,500 to $4,000
Skylight	$800 to $2,500

Quotes that fall significantly below these ranges often reflect lower-grade materials, thinner glass packages, or labour shortcuts that show up later as drafts or water infiltration. Getting at least three quotes from pros gives you a reliable picture of what the work should realistically cost in your area.

A Breakdown: How Much Does It Cost to Install Windows?

Window installation quotes bundle several cost components together, and contractors package them differently. Knowing what each one contributes helps when you are comparing quotes side by side.

Labour

Labour on a standard residential window installation runs $100 to $300 per window for a ground-floor replacement in an existing opening. That covers removing the existing unit, fitting and securing the new one, sealing the perimeter, and basic interior trim. Several factors push the labour cost higher:

• Scaffolding: upper-floor windows requiring scaffold setup typically add $200 to $500 to the job, spread across however many windows are on that level.
• Framing adjustments: if the rough opening needs to be resized or reframed, expect an additional $150 to $400 per opening depending on the extent of the work.
• Day rates: on full-house replacements of eight or more windows, some contractors shift to a day rate rather than per-window pricing, typically $600 to $900 per installer per day.

Frame materials

Frame material is one of the most significant cost variables in a window installation quote. The choice affects not just the upfront cost but also maintenance requirements, thermal performance, and how the frame holds up over time in Canadian climate conditions.

Frame material	Typical cost per window (frame and sash only)
Vinyl	$150 to $400
Wood	$300 to $700
Fibreglass	$250 to $600
Aluminum	$200 to $500
Wood-clad (aluminum or fibreglass exterior)	$400 to $900

• Vinyl is the most common choice in Canadian residential construction: low maintenance, affordable, and widely available.
• Wood costs more and requires periodic painting or staining but is preferred where interior aesthetics are a priority.
• Fibreglass handles Canadian temperature swings well and sits between vinyl and wood on price.
• Aluminum is common in commercial and condo applications but less so in detached residential.
• Wood-clad frames give the look of wood inside with a lower-maintenance exterior shell.

Glazing

Glazing refers to the glass package: the number of panes, the gas fill between them, and any Low-E coating. Double-pane windows are standard in Canadian residential construction and add roughly $50 to $200 to the unit cost depending on size and coating spec. Triple-pane glazing runs $100 to $300 more per window than double-pane and makes the most sense in colder provinces where heating costs are a significant household expense.

Permits and inspections

Most standard window replacements in an existing opening do not require a permit. Structural changes to an opening, adding a new opening, or installing egress windows in bedrooms typically do. Permit fees vary by municipality but generally fall in the $100 to $300 range. Your contractor should identify permit requirements before work starts and either include the permit cost in the quote or clearly note that it is excluded.

Costs for Different Window Types

Window style affects both the unit cost and the complexity of installation. The right choice for a given opening depends on ventilation needs, how well the window seals for thermal and noise performance, and how the style suits the room and the home's architecture.

Single-hung and double-hung windows

Single-hung windows, where only the bottom sash opens, are the most straightforward to install and typically the least expensive option. Installed costs for a standard vinyl unit run $300 to $600. Double-hung windows, where both sashes open, cost slightly more due to the more complex mechanism, typically $400 to $800 installed. Both fit standard rectangular openings and install efficiently on multi-window jobs.

Casement windows

Casement windows open on a side hinge and seal tightly when closed, which gives them a slight edge in airtightness over sliding-sash styles. The crank mechanism adds to the unit cost. Installed costs typically run $450 to $900 per window, with size and glazing package driving most of the variation within that range.

Sliding windows

Sliding windows operate on a horizontal track and are a practical choice for basement and garage openings where a crank or sash mechanism would be awkward. Installation is generally straightforward, and installed costs run $350 to $750 for a standard unit.

Awning windows

Awning windows hinge at the top and open outward, which allows ventilation even during light rain. They are often paired with fixed windows in larger openings. Installed costs run $400 to $850, with the hinge hardware and operator adding to the unit cost compared to simpler fixed or sliding windows.

Bay and bow windows

Bay and bow windows project outward from the exterior wall and require more structural support than a flat replacement. A bay window, typically three panels at an angle, costs $1,500 to $4,000 installed. A bow window, with four or more curved panels, runs $2,500 to $5,500 or more depending on width. These are rarely straightforward replacements and carry more risk of cost overruns on older homes where the opening needs reinforcing.

Skylights

Skylight installation costs depend heavily on roof pitch, structural requirements, and whether a light shaft needs to be built down through the ceiling. A fixed skylight costs $800 to $1,500 installed. Venting skylights range from $1,200 to $2,500 or more. Flat or low-pitched roofs complicate waterproofing and push costs toward the higher end of those ranges.

Window Installation Cost: Per Window vs. Full

The cost per window changes depending on the scope of work. Single replacements, multi-window jobs, and new construction installations each carry different pricing dynamics.

Single-window replacements

Replacing one window typically costs more per unit than a multi-window job. Mobilisation costs, including travel time and setup, are spread across fewer windows, and contractors rarely discount standard rates for a single unit. For a standard double-hung or casement replacement, expect to pay toward the higher end of the typical range, often $500 to $1,000 installed.

Multi-window replacements

Full-house replacements, or any job involving five or more windows, generally attract a lower per-window rate. Contractors can work more efficiently across a single property, reduce setup time per opening, and often negotiate better pricing on a larger material order. On a ten-window replacement with standard vinyl double-pane units, a per-window rate of $400 to $700 is a reasonable benchmark, though regional labour rates and home type affect this.

New construction installations

New construction window installation differs from replacement work because there is no existing window to remove and the rough opening is already framed to specification. Labour costs per window are typically lower, running $75 to $200 per window, but the number of windows in a new build means the total project cost is substantial. A new build with fifteen windows could see total installation labour of $1,500 to $4,000 before materials.

Tips to Save on Window Installation Costs

With a little planning, there are several ways to cut down on window installation costs without sacrificing quality. Here are some of the most common ones:

• Timing: booking in the off-season (late fall or winter) when installers are slower can bring lower pricing or better deals
• Replacing vs. full removal: insert/retrofit installation (keeping the existing frame) costs less than full-frame replacement, where it's structurally sound to do so
• Doing multiple windows at once: installers typically charge less per window on larger jobs since mobilization costs are spread out
• Getting multiple quotes: pricing varies meaningfully between companies; three quotes is a reasonable baseline
• Rebate programs: provincial and utility programs occasionally offer rebates for window upgrades that meet specified Energy Star efficiency ratings, such as the BC Hydro program for window and door rebates
• Standard sizing: custom or non-standard window sizes cost more; where possible, choosing standard dimensions brings the price down
• Material choice: vinyl frames cost less than wood or fibreglass and still perform well in Canadian climates
• Avoiding unnecessary upgrades: triple-pane is worth it in colder climates but may be overkill for a mild coastal region; matching the spec to the climate avoids overspending

Your Questions About Window Installation Costs Answered

How long does window installation take?

A straightforward replacement of a single standard window typically takes one to two hours per window. A full-house replacement of eight to twelve windows can often be completed in one or two days. More complex work, including bay windows, skylights, or openings that need structural framing changes, takes longer and varies considerably by job. You can post your job on HomeStars and connect with window installation pros in your area who can give you a realistic timeline for your specific project.

Do window installation costs vary by province?

Yes, and the differences can be significant. In major urban centres like Toronto and Vancouver, labour rates run higher than in smaller markets, and this can add $50 to $150 per window to the total installed cost compared to mid-sized Prairie or Atlantic cities. Material costs are more consistent nationally, though some specialty products have longer lead times outside major centres, which can affect scheduling.

What is the difference between insert and full-frame window replacement?

Insert replacement installs the new window unit into the existing frame, which is faster and less disruptive but requires the existing frame to be in good structural condition. Full-frame replacement removes everything down to the rough opening and installs a new frame and casing. Full-frame work typically adds $100 to $200 per window to the cost, but it is necessary when the existing frame is rotted, out of square, or has moisture damage, since skipping it when the frame is compromised often leads to air leakage and water problems within a few years.

What questions should I ask a window installation pro before hiring?

Ask whether the quote includes removal and disposal of the existing window, whether trim and interior finishing are included or billed separately, and whether they handle permit applications if a permit is required. Also ask what warranty covers the window unit itself versus the installation labour, since these are often different coverage periods from different parties. Getting clarity on these points before work starts avoids most of the common disputes that come up mid-job.
