How Much Does Window Replacement Cost in 2026?
Window replacement costs $300-$1,200 per window installed in 2026, with most homeowners spending $6,000-$20,000 for a full house replacement. The price range is wide because frame material, window style, size, and labor rates vary significantly by region. Vinyl double-hung windows — the most common choice — cost $300-$650 each installed. Premium fiberglass or wood windows run $600-$1,500 each. Specialty windows like bay, bow, or egress can reach $2,500-$6,500 per opening.
Window Replacement Cost by Style (2026)
Window style is one of the biggest cost drivers because complexity of the frame, hardware, and installation varies:
- Double-hung ($300-$1,100 installed): The most common U.S. window style — both sashes slide up and down. Good ventilation, easy to clean. Vinyl versions start at $300; wood versions reach $1,100+.
- Casement ($400-$1,200 installed): Hinged on one side, crank-open mechanism provides excellent sealing and ventilation. Better energy performance than double-hung. Costs 15-25% more due to hardware complexity.
- Slider ($300-$900 installed): Sashes slide horizontally. Simpler hardware than casement, similar cost to double-hung. Popular in contemporary and ranch-style homes.
- Picture / Fixed ($200-$700 installed): Non-opening, maximum light and view. Cheapest per unit since there's no hardware. Often combined with casement or awning windows for ventilation.
- Awning ($400-$1,000 installed): Hinged at top, opens outward. Good for ventilation in rainy climates — can stay open during light rain. Similar cost to casement.
- Bay or Bow ($1,500-$4,500 installed): Three to five windows angled outward, creating a projection from the exterior wall. Requires structural framing, roof extension, and significant carpentry labor. Most expensive residential window type.
- Egress ($2,500-$6,500 installed): Code-required in basement bedrooms for emergency egress. Requires enlarging the opening, cutting through foundation or concrete block, and installing a window well. Excavation adds significant cost.
Window Replacement Cost by Frame Material (2026)
Frame material affects upfront cost, maintenance requirements, energy performance, and lifespan:
- Vinyl ($300-$750 per window installed): Most popular material — zero maintenance, good insulation, never needs painting. Mid-range brands (Andersen 100 Series, Simonton, Pella 150) offer excellent value at $400-$650 installed.
- Fiberglass ($600-$1,200 per window installed): Best insulation performance (72% better than vinyl in some tests). Expands and contracts at same rate as glass, reducing seal failures. 40-50 year lifespan. Marvin, Andersen E-Series, and Integrity are leading brands.
- Wood ($700-$1,500 per window installed): Best aesthetics and historical authenticity. Requires painting or staining every 5-10 years. Interior wood with exterior aluminum cladding (clad-wood) offers best of both worlds at $900-$1,400 installed.
- Aluminum ($300-$900 per window installed): Strong, slim frames with maximum glass area. Poor thermal performance without a thermal break. Common in commercial applications and modern architecture.
- Composite / Clad ($600-$1,300 per window installed): Fiberglass or composite exterior with wood interior. Combines low exterior maintenance with warm interior aesthetics. Andersen 400 Series and Marvin Integrity are popular options.
Window Replacement Cost in San Diego (2026)
San Diego window replacement costs run 25-30% above national averages. Key factors specific to San Diego:
- Labor rates: Window installation crews in San Diego charge $75-$150/hr vs. $50-$90/hr nationally. A 15-window job adds $1,500-$3,000 in labor above national averages.
- Permit requirements: San Diego requires permits for window replacements that change opening size. Permit fees run $200-$800 depending on scope. Standard like-for-like replacements may be exempt.
- Energy rebates: SDG&E offers rebates for ENERGY STAR certified windows: typically $25-$75 per window.
- Climate considerations: San Diego's mild climate means triple-pane windows rarely pay back. Dual-pane Low-E glass with argon fill (standard on most mid-range windows) is optimal.
- Lead time: Supply chain for premium window brands (Andersen, Marvin, Milgard) runs 6-10 weeks in San Diego — plan ahead.
Hidden Costs of Window Replacement
- Permit fees: $200-$800 for full replacements in most California cities. Required when changing window opening size or count.
- Structural work: Enlarging openings for egress or bay windows requires structural engineering and permits — add $1,500-$5,000.
- Exterior trim and casing: New windows often need exterior trim, caulk, and paint touchup — $100-$300 per window.
- Interior patching: Drywall damage around the frame, casing repaint, and stool/apron replacement — $50-$200 per window.
- Lead paint testing: Homes built before 1978 may require lead testing before window removal — $200-$500 for a full home inspection.
- Haul-away: Disposal of old windows costs $50-$200 depending on count; some installers include this, others charge separately.
How to Save on Window Replacement
- Get 3 or more bids: Window installation prices vary 30-50% between contractors. Insist on the same brand, model, and glass package in each bid.
- Replace all windows at once: Per-window price drops 15-25% when doing a full house vs. individual replacements.
- Choose mid-range vinyl: Andersen 100 Series, Milgard Tuscany, or Simonton 5500 hit the sweet spot of quality, efficiency, and cost at $400-$650 installed.
- Skip triple-pane in mild climates: Triple-pane adds $100-$200 per window and pays back over 30+ years in mild climates like San Diego — not worth it.
- Claim ENERGY STAR tax credits: Federal tax credit of 30% up to $600 for ENERGY STAR certified windows. Ask your contractor for certificates.
