Window Replacement Costs Across Canada — 2026
Full-house window replacement for a typical home ranges from $12,000 to $35,000 across four Canadian provinces, with significant cost variations driven by climate requirements and local building codes. New Brunswick shows the widest range at $12,000–$36,000 for a 2,000 square foot home with 15-20 windows, while Ontario projects cluster between $12,000–$20,000 for comparable 12-18 window installations.
The cost structure reveals clear differences between individual window replacement and whole-house projects. Single premium windows range from $800–$2,000 per unit for high-end materials like fiberglass or solid wood, while basic vinyl replacements start at $300–$600 per unit in Alberta. British Columbia shows similar individual unit costs, with triple-pane installations running $800–$1,500 per unit including labor.

| Premium 1,200 sq ft project | $28,000 | $35,000 | Project | AB |
| Mid-range 1,200 sq ft project | $22,000 | $28,000 | Project | AB |
| Basic 1,200 sq ft project | $18,000 | $22,000 | Project | AB |
| Premium individual window | $800 | $2,000 | Per unit | BC, AB |
| Mid-range individual window | $500 | $1,200 | Per unit | All provinces |
| Basic vinyl window | $300 | $800 | Per unit | All provinces |
| Basement egress installation | $3,000 | $15,000 | Per unit | AB, BC, NB |
| Heritage window restoration | $800 | $3,000 | Per unit | All provinces |
Alberta projects consistently price higher than comparable installations in other provinces, reflecting the province's extreme climate requirements. The Alberta Building Code mandates specific performance standards for windows facing chinook conditions and temperature swings exceeding 60°C annually. Triple-pane installations with argon fill are standard rather than premium upgrades, driving base costs upward. Additionally, winter installation surcharges of $1,800–$5,250 reflect the necessity of heated workspaces and material protection during Alberta's extended cold periods.
British Columbia costs vary dramatically based on housing type and seismic requirements. The BC Building Code incorporates earthquake-resistant installation methods that add complexity to frame attachment and weatherproofing. Vancouver Specials, with their unique window configurations, command $15,000–$45,000 for full replacement due to custom sizing requirements. Coastal moisture exposure necessitates enhanced weatherproofing systems, particularly around window wells and trim connections.
New Brunswick's pricing reflects older housing stock and challenging installation conditions. The province's building code requires 5-6 foot frost line considerations for foundation-level windows, making egress installations particularly expensive at $2,000–$4,000 per unit. Heritage properties throughout the Maritimes require specialized restoration work ranging $800–$2,500 per window, as heritage compliance standards are strictly enforced under municipal preservation bylaws.
Specialized Installation Requirements
Egress window installations represent significant cost variations between provinces. Alberta shows the widest range at $3,000–$15,000 per installation, reflecting both basic code compliance and complex basement enlargement projects requiring structural modifications. The Safety Codes Council of Alberta requires specific drainage and well construction standards that can double project costs depending on existing foundation conditions.
Heritage restoration work commands premium pricing across all provinces, with individual window restoration ranging $800–$3,000 per unit. This reflects the specialized labor required for sash rebuilding, traditional glazing techniques, and hardware restoration. Ontario's Heritage Conservation Districts and British Columbia's heritage protection zones often mandate these restoration approaches over replacement, making cost planning crucial for older property owners.
Energy efficiency upgrades drive significant cost premiums but offer measurable returns. Triple-pane installations with low-E coatings and argon fill typically add $200–$400 per window over standard double-pane units. Alberta offers EnerGuide evaluations for $500–$1,500 to qualify for federal and provincial rebates, while other provinces rely on utility programs for energy efficiency incentives.
Winter installation requirements add substantial costs in Alberta, where heated workspace and material protection can increase project costs by 15-20%. British Columbia's rainy season creates similar installation challenges, though less severe than Alberta's temperature extremes. WorkSafeBC and WCB Alberta both mandate specific cold-weather safety protocols that extend installation timelines and increase labor costs.
