How Much Does Window Replacement Cost in BC?

You’re replacing windows. You want a number.

The problem is that “window replacement cost” in Metro Vancouver ranges from $400 to $5,000+ per window depending on factors that aren’t obvious until you’re actually getting quotes. Online searches return everything from suspiciously low numbers to eye-watering totals, and most homeowners can’t tell which applies to their home without spending hours decoding contractor quotes.

Before you get a single quote, check whether you actually need replacement or repair — because repair is sometimes the right answer. But if you’re past that question and genuinely replacing windows, this guide gives you honest 2026 pricing for Metro Vancouver, explains what drives cost up or down, and helps you evaluate quotes intelligently.

After 35+ years manufacturing windows locally in Delta, BC, we’ve watched pricing cycles, material cost shifts, and the labour market evolve. These numbers reflect what homeowners are actually paying in Metro Vancouver in 2026 — not national averages that underestimate BC costs.

The Short Answer: 2026 Price Ranges

Before diving into detail, here are realistic installed cost ranges for Metro Vancouver:

Standard vinyl windows (retrofit/insert installation): $600 – $1,400 per window

Standard vinyl windows (full-frame installation): $900 – $1,800 per window

European tilt-and-turn windows: $1,200 – $2,400 per window

Thermally-broken aluminum windows: $1,400 – $3,000+ per window

Specialty windows (bay, bow, large picture): $2,000 – $6,000+ per unit

Egress windows (including foundation work): $3,500 – $8,000+ per window

These are installed costs including product, labour, disposal of old windows, and standard trim work. They don’t include structural modifications, foundation cutting, or permit fees where required.

A typical Metro Vancouver home with 12-15 windows runs $12,000-$25,000 for a complete replacement project depending on window styles, glazing specifications, installation method, and any structural work required.

What Drives Cost: The Seven Variables

Understanding these seven factors lets you decode any quote and understand why your neighbour’s cost was different from yours.

1. Retrofit vs. Full-Frame Installation

This single decision affects cost more than almost any other factor, and many homeowners don’t understand the difference until they’re mid-project.

Retrofit (insert) installation: New window sash and frame insert into existing rough opening, typically leaving exterior casing and interior trim in place. Less invasive, faster, lower labour cost.

Full-frame installation: Existing window, frame, casing, and interior trim completely removed. New window installed from scratch with new flashing, wrapping, and trim.

The difference between nail flanges and renovation flanges determines which installation method your windows require. Renovation flanges work over existing exterior cladding in retrofit situations. Nail flanges require full-frame installation where exterior cladding is disturbed.

Cost difference: Retrofit installation typically costs $200-$400 less per window than full-frame. On a 15-window project, that’s $3,000-$6,000 difference.

When each is appropriate:

Retrofit works when existing frames are structurally sound, plumb, and square — no rot, no water damage, no significant gaps or movement. Interior and exterior cladding stays intact.

Full-frame is required when existing frames are rotting, damaged, or when you’re changing rough opening size. Also required for certain installation methods that affect energy performance and Step Code compliance.

The hidden risk of automatic retrofit: Some contractors quote retrofit on every job because it’s faster and cheaper to install. But pre-1985 Metro Vancouver homes often have frame rot that’s invisible until the window comes out. Budget for the possibility of full-frame work on older homes, and ask your contractor what happens to the price if rot is discovered mid-project.

2. Window Style and Hardware Complexity

Different window styles have meaningfully different costs due to hardware, manufacturing complexity, and installation requirements.

Single-slider windows: Least expensive. One panel slides behind the other, minimal hardware. $600-$1,000 installed for standard sizes.

Single-hung windows: Similar to slider but vertical operation. One sash slides up. Slightly more hardware than sliders. $650-$1,100 installed.

Casement and awning windows: Crank operation, compression sealing, hinges. 15-20% premium over sliders. $750-$1,300 installed. Better sealing performance justifies the difference for many applications.

Tilt-and-turn windows: Dual-operation German hardware, multi-point locking, compression seals. 30-40% premium over sliders. $1,200-$2,400 installed. Premium buys genuine performance and functionality differences.

Fixed (picture) windows: No hardware or moving parts — lower cost than operable windows of comparable size. $500-$1,200 depending on size and glazing.

Bay and bow windows: Three or more window units projecting outward with structural framing. Complexity and structural work drive costs to $2,500-$6,000+ for typical residential sizes.

3. Glazing Specification

Double-pane or triple-pane is the most common glazing question, but the full picture is more nuanced.

Standard double-pane, argon, single Low-E: Baseline pricing. Meets current BC Building Code minimum. Adequate for most applications.

Triple-pane, argon, dual Low-E: Adds 15-25% to window cost. Justified for north-facing rooms with high heating loads, homes targeting Step Code compliance, or homeowners prioritizing long-term energy savings.

Krypton gas fill (instead of argon): Better thermal performance in thinner spaces — used in some triple-pane configurations. Modest cost premium ($50-$150 per window) for meaningful performance improvement.

Tempered glass: Required by BC Building Code in certain locations (within 600mm of doors, in bathrooms below certain heights, sidelights). Adds $80-$200 per window where required. Not optional — it’s a code requirement.

Obscured/frosted glass: For bathrooms and privacy applications. Adds $50-$150 per window over clear glass.

Laminated glass: Holds together when broken rather than shattering. Used for security applications, noise reduction, skylights. Adds $100-$250 per window.

4. Frame Material

Vinyl, aluminum, and hybrid options have genuinely different cost profiles.

Premium vinyl (multi-chamber uPVC): $600-$1,400 per window installed. Most popular choice in Metro Vancouver — low maintenance, excellent energy performance, proven BC climate durability.

Thermally-broken aluminum: $1,400-$3,000+ per window installed. Pays for slim sightlines, contemporary aesthetics, and structural strength for large openings. Genuine performance when properly engineered.

Fiberglass: $1,000-$2,000 per window installed. Superior dimensional stability, paintable, premium durability. Less common in BC than Eastern Canada.

Wood or clad-wood: $1,200-$2,500 per window installed. Appropriate for heritage homes, premium aesthetics. Higher maintenance requirements.

Color and finish: White vinyl frames are base pricing. Any other colour — black, bronze, grey, woodgrain — typically adds $80-$200 per window. Popular contemporary colours (matte black, anthracite) command premiums.

5. Window Size and Custom Sizing

Standard window sizes cost less than custom sizes because they’re manufactured to common dimensions rather than individually specified.

Standard sizes for common window types (approximately 24″×36″, 30″×48″, 36″×48″) represent the most cost-effective options. Pricing guides typically reference these sizes.

Custom sizing adds cost in two ways: Manufacturing cost increases for non-standard dimensions, and installation complexity often increases when modifying rough openings to accommodate custom sizes.

Custom windows make sense when standard sizes don’t fit your openings, when you’re enlarging or changing window configurations, or when architectural requirements demand specific dimensions. The premium is real but sometimes unavoidable.

Large windows: Cost increases non-linearly with size. A window twice the area doesn’t cost twice as much — it costs more, because large glass panels require stronger frames, more complex hardware, and more careful installation.

6. Installation Complexity

Labour is typically 40-55% of total window replacement cost in Metro Vancouver. Several factors drive labour costs higher:

Access difficulty: Second and third-floor windows, steep-roofed homes requiring extended ladders, tight yard access. Add $50-$150 per window for difficult access.

Interior finish work: Standard quotes include basic interior trim reinstallation. Complex interior trim, custom millwork, or heritage restoration requires additional carpentry time and cost.

Rot and damage discovery: Pre-1985 homes with original frames commonly have concealed rot. When discovered mid-project, addressing it properly adds $200-$600 per affected window in additional labour and materials.

Stucco and stone exteriors: More complex exterior sealing and waterproofing than standard vinyl siding. Add $100-$200 per window for stucco homes.

How long window replacement takes also depends on these complexity factors — a straightforward 15-window retrofit might complete in one day, while a complex full-frame project with rot remediation takes three or four days.

7. Project Size

Per-window costs decrease as project size increases. Why? Setup costs, travel, and some overhead costs don’t scale proportionally.

Single window replacement: $800-$1,400+ per window — highest per-unit cost due to setup costs that don’t amortize across multiple units.

5-10 window project: $700-$1,200 per window average.

Full home replacement (12-20 windows): $600-$1,100 per window average — best per-unit pricing.

This creates practical advice: if you have one urgent window and several others within 5 years of needing replacement, replacing them all together typically saves money over doing them separately.

The Retrofit vs. Full-Frame Cost Breakdown

Because this distinction matters so much, here’s a more detailed look at what you’re actually paying for in each approach.

Retrofit Installation Cost Components

Window product: 50-60% of total
Labour (removal, fitting, sealing, trim): 35-45%
Materials (caulk, foam, fasteners): 5-10%
Disposal of old windows: Often included, sometimes extra

What you’re NOT paying for in retrofit: Exterior cladding work, new flashing, full perimeter waterproofing, interior finishing beyond basic trim replacement.

The risk: Retrofit relies on existing exterior waterproofing remaining intact. If underlying flashing or housewrap is compromised, retrofit installation may not address it. Fine for sound existing frames; problematic for anything with age-related deterioration.

Full-Frame Installation Cost Components

Window product: 40-50% of total
Labour (complete removal, framing, waterproofing, finishing): 45-55%
Materials (flashing, housewrap, foam, fasteners, trim): 10-15%
Disposal: Usually included

What you’re paying for in full-frame: Complete envelope integration, new flashing, new housewrap or waterproofing at perimeter, opportunity to address any discovered issues.

The benefit: Properly done full-frame installation provides the best possible weather sealing and is the only way to address underlying issues discovered during removal.

Permit Fees: What to Budget

Whether you need a permit for window replacement in Metro Vancouver depends on what you’re doing:

Straight retrofit in same opening, same size: Generally no permit required in most Metro Vancouver municipalities. Confirm with your local building department.

Enlarging openings, adding new windows, changing opening sizes: Building permit required. Involves structural review of modified framing.

Egress window installation in basement: Permit required regardless of whether opening size changes.

Secondary suite windows: Permit requirements vary by municipality and suite type.

Permit costs in Metro Vancouver: $100-$300 for residential window work where permits are required. Inspection fees may add $50-$150.

Skipping permits when required creates problems at resale when home inspection reveals unpermitted work. The permit cost is modest — don’t cut this corner.

Strata Properties: The Approval Layer

If you own a strata townhouse, condo, or property with shared governance, window replacement involves an additional layer beyond permits.

Strata window replacement in BC requires strata council approval before work begins. Exterior windows are typically common property even when “in your unit,” meaning:

You need written strata approval before ordering or installing
Windows must match building appearance standards
Some stratas specify approved products or contractors
Approval process typically takes 4-8 weeks for straightforward requests

Budget additional time for strata approval. Don’t order windows before approval is received — strata can require removal and replacement if unapproved windows are installed.

Rebates That Reduce Your Net Cost

CleanBC programs can meaningfully offset window replacement costs for qualifying BC homeowners.

Our complete guide to CleanBC rebates for window replacement covers current programs in detail, but here’s the current picture:

CleanBC Better Homes Energy Savings Program (income-qualified): Up to $9,500 total, maximum $950 per window or door. Based on household income and number of occupants. Requires Energy Star-certified windows and professional installation.

BC Hydro and FortisBC rebates: Available to customers replacing windows with Energy Star Most Efficient products. Rebates typically $20-$75 per window. Modest individually, meaningful on whole-home projects.

Federal programs: Canada Greener Homes Grant has varied by year — check current availability at the time of your project.

Key rebate requirements:

Energy Star certification with documented U-factors
Professional installation by registered contractor
Proper documentation including itemized invoices
Cannot be combined with certain other programs for the same upgrade

Practical net cost example: 15-window project at average $1,000/window = $15,000 gross CleanBC income-qualified rebate = $9,500 Net cost = $5,500 for qualifying households

Even for non-income-qualified homeowners, Energy Star rebates reduce net cost by $300-$1,000 on typical projects.

Why the Cheapest Quote Costs More

You’ll get quotes ranging widely for the same project. Understanding why helps you evaluate them properly.

The hidden cost of cheap windows is a longer discussion, but the short version: budget windows typically fail at hardware, seals, and weatherstripping first. These failures arrive 5-8 years after installation rather than 20-25 years. The replacement cost plus second installation labour exceeds what quality windows would have cost originally.

Similarly, the cost of quality explains why well-engineered windows cost more upfront and less over their lifetime. Frame material quality, hardware durability, seal longevity, and glass performance all affect the 25-year cost of window ownership — not just the day-one price.

The ROI of window replacement is measurable: energy savings, reduced maintenance, resale value improvement, comfort gains. These returns don’t come from the cheapest windows — they come from windows that perform as specified for 20+ years.

Red flags in low quotes:

No mention of installation method (retrofit vs full-frame)
Vague glazing specifications (“double-pane glass” without U-factor)
No mention of permit requirements
No warranty terms specified
Unusually fast quoted installation times
No discussion of what happens if rot is discovered
