Quick Answer: Replacing one window costs $300–$1,100 installed. A mid-range double-hung window costs about $400 for materials plus 2 hours of carpenter labor at your local rate (× 1.5 burden). For 8 windows, expect $5,000–$9,000 total including 20% contractor markup. Costs vary 40–75% by metro area — carpenter rates range from $20/hr in low-cost cities to $38+/hr in Chicago or New York. Enter your ZIP code above for a location-specific estimate based on Bureau of Labor Statistics data, plus Census housing age data — homes built before 1980 often have single-pane windows where replacement improves energy efficiency 25–30%.

How Window Replacement Cost Is Calculated
Window replacement cost has four components:
- Window materials — The window unit itself, including frame, glass, hardware, and weatherstripping. Prices vary by type (single-hung is cheapest, casement is most expensive) and quality tier (basic vinyl to premium fiberglass).
- Installation labor — Carpenter hourly rate from BLS data for your metro area, multiplied by hours per window (1.25–2.0 depending on type) and a 1.5x burden factor for payroll taxes, insurance, and benefits.
- Fixed costs — Permit fees ($150 per job) and old window disposal ($25 per window).
- Contractor markup — Standard 20% overhead and profit on the subtotal.
Window Replacement Cost by Type
Material and labor costs vary significantly by window style:
| Window Type | Material Cost | Labor Hours | Best For |
|---|---|---|---|
| Single-Hung | $150–$550 | 1.5 hr | Budget replacements, most common |
| Double-Hung | $200–$700 | 2.0 hr | Easy cleaning, good ventilation |
| Casement | $225–$800 | 2.0 hr | Best seal, maximum airflow |
| Picture/Fixed | $175–$650 | 1.25 hr | Views, no ventilation needed |
Window Material Quality Tiers
- Basic (vinyl): Most affordable option at $150–$300 per window. Vinyl frames are low-maintenance, resist moisture, and offer good insulation. Lifespan 20–30 years. Best for budget-conscious replacements.
- Mid-range (wood/composite): $300–$450 per window. Composite frames combine the look of wood with lower maintenance. Wood interiors with vinyl or aluminum cladding on the exterior offer a traditional aesthetic. Lifespan 30–40 years.
- Premium (fiberglass/clad): $550–$800 per window. Fiberglass frames are the strongest, most energy-efficient option. They expand and contract at the same rate as glass, maintaining a tight seal. Lifespan 40–50+ years.
Why Window Costs Vary by Location
- Carpenter labor rates: BLS data shows carpenter wages range from $20/hr (25th percentile, low-cost metros) to $38+/hr (75th percentile, high-cost metros like Chicago and New York). Labor is 25–40% of total window replacement cost.
- Permit requirements: Some municipalities require permits for window replacement, especially when changing window size or structural framing. Permit fees range from $50–$300.
- Energy code requirements: Colder climates often require higher U-factor and SHGC ratings, which may limit you to more expensive window options. Energy Star requirements vary by climate zone.
- Market competition: Areas with more window installers tend to have more competitive pricing. Rural areas with fewer contractors may charge premium rates.
Cost Formula Summary
Window Replacement Cost Formula:
Material Cost = Window Count × Material Cost Per Window
Labor Cost = Window Count × Hours/Window × Hourly Rate × 1.5 (burden)
Fixed Costs = $150 (permits) + Window Count × $25 (disposal)
Total = (Material + Labor + Fixed) × 1.20 (markup)

Standard assumptions: Labor burden of 1.5x covers FICA (7.65%), workers' comp (8–15% for carpentry), general liability, and benefits. Contractor markup of 20% covers overhead and profit. Low/high range uses BLS 25th and 75th percentile hourly wages; mid-range uses mean wage. Material costs reflect 2024–2025 retail pricing for standard residential sizes.
