Window Replacement Cost Calculator

By Taro Schenker | Updated February 19, 2026

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%.

Estimate the cost to replace windows in your home using real labor rate data from the Bureau of Labor Statistics. This calculator covers 393 US metro areas and lets you compare costs across window types and quality tiers. Select your window style, choose a quality level, and enter your ZIP code for a location-specific estimate.

How Window Replacement Cost Is Calculated

Window replacement cost has four components:

Total = (Materials + Labor + Fixed Costs) × 1.20
  1. 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).
  2. 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.
  3. Fixed costs — Permit fees ($150 per job) and old window disposal ($25 per window).
  4. 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 TypeMaterial CostLabor HoursBest For
Single-Hung$150–$5501.5 hrBudget replacements, most common
Double-Hung$200–$7002.0 hrEasy cleaning, good ventilation
Casement$225–$8002.0 hrBest seal, maximum airflow
Picture/Fixed$175–$6501.25 hrViews, 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.

Frequently Asked Questions

How much does it cost to replace a window?
The average cost to replace one window is $300–$1,100 including materials and labor. A basic vinyl single-hung window runs $300–$500 installed. A mid-range double-hung costs $600–$800. Premium fiberglass or wood-clad windows can cost $900–$1,500 per window. Labor alone is typically $150–$400 per window depending on your location and window type.
How much does it cost to replace all windows in a house?
For a typical home with 8–15 windows, full replacement costs $4,000–$15,000. A 10-window job with mid-range double-hung windows averages $6,000–$9,000 including labor, materials, permits, and disposal. The per-window cost decreases slightly with larger jobs since fixed costs (permits, setup) are spread across more windows.
What type of replacement window is most cost-effective?
Vinyl single-hung windows offer the best value at $150–$300 per window for materials. They require minimal maintenance, provide good insulation, and last 20–30 years. Double-hung vinyl costs slightly more ($200–$400) but offers easier cleaning since both sashes tilt in. For most homes, mid-range vinyl or composite windows provide the best balance of cost, energy efficiency, and longevity.
Does the age of my home affect window replacement needs?
Yes. Homes built before 1980 typically have single-pane windows with poor energy efficiency (U-factor 1.0+). Replacing them with modern double-pane Low-E windows (U-factor 0.25–0.30) can reduce heating and cooling costs by 25–30%. Pre-1978 homes may also have lead paint on window frames, requiring certified lead-safe work practices that add $50–$100 per window. Our calculator shows your area's median home construction year from Census data when you enter your ZIP.
Does replacing windows increase home value?
Yes. Window replacement typically recoups 60–75% of the cost at resale according to Remodeling Magazine's Cost vs. Value Report. Vinyl window replacement averages a 67% return, while wood windows average 61%. Beyond resale value, new windows reduce energy bills by 12–25% and improve comfort, noise reduction, and curb appeal.
How long does it take to replace a window?
A professional installer can replace one standard window in 1.5–2 hours. A full-house replacement of 10 windows typically takes 2–3 days. Factors that add time include: custom sizes, structural damage around the frame, switching from one window type to another (e.g., single-hung to casement), and second-story windows requiring scaffolding.
Should I replace windows myself or hire a contractor?
DIY window replacement can save 30–50% on labor costs, but it requires carpentry skills, proper tools, and knowledge of flashing and weatherproofing. Mistakes can lead to water damage, air leaks, and voided manufacturer warranties. Professional installation is recommended for: structural window changes, second-story windows, windows with rot or water damage, and any window replacement where the warranty requires professional installation.
