Double Hung Window Replacement Cost Guide

Key Takeaways

• Double-hung window replacement runs $400-1,000 per window installed in 2026, with vinyl at the low end and wood at the high end.
• Double-hung units cost $50-150 more than single-hung because both sashes tilt in for cleaning.
• The glass package is the biggest variable: double-pane low-E argon adds $100-200, triple-pane $200-400 per window.
• Double-hung is the most common window in America, so stock sizes and installer experience keep prices competitive.

What Double-Hung Windows Cost, 2026

• Vinyl double-hung: $250-600 material, $400-800 installed. The default choice for 60%+ of U.S. replacements; low-maintenance and energy-efficient with modern multi-chamber frames.
• Wood double-hung: $500-1,200 material, $700-1,600 installed. Required in many historic districts; needs painting or staining every 5-10 years.
• Fiberglass double-hung: $600-1,200 material, $800-1,600 installed. The most dimensionally stable frame; holds paint longest and performs best in extreme climates.
• Composite and aluminum-clad: $500-1,100 installed; wood core with vinyl or aluminum exterior for low maintenance.
• Full-frame vs. insert replacement: insert (pocket) installs run 20-30% less because the old frame stays; full-frame removal costs more but fixes rotted sills and improves energy performance.

Why Double-Hung Costs More Than Single-Hung

The double-hung design, two vertically sliding sashes that both tilt inward for cleaning, adds hardware, balances, and complexity over a single-hung unit. That engineering costs $50-150 more per window, and it is worth it for most homeowners: tilt-in cleaning means you never need to clean the exterior from a ladder, which is why double-hung dominates replacement sales despite the premium. The counterweight-and-pulley systems in old wood windows are also the reason historic replacements cost more: installers must remove the weights, insulate the pockets, and retrofit modern balances.

Glass Package: The Hidden Price Driver

• Double-pane clear: baseline, included in most quotes.
• Double-pane low-E with argon: +$100-200 per window; the standard upgrade that qualifies for the 30% federal tax credit (up to $600/year).
• Triple-pane: +$200-400 per window; best in cold climates, adds weight that needs sturdier frames.
• Impact-resistant laminated glass: +$500-1,500 per window; required by code in hurricane zones.
• Grids, divided lites, and custom colors: +$50-300 per window.

Regional Differences

Double-hung pricing tracks labor markets: $350-600 installed in the Southeast and Midwest, $500-900 in the Northeast and West Coast. Cold-climate states see higher glass costs because low-U-factor packages are effectively mandatory. Hurricane zones force impact glass, pushing double-hung replacements to $1,200-2,500 installed. Historic districts add 50-100% for wood units with period profiles and approval processes.

Hidden Costs to Budget For

• Old window removal: $25-100 per window; lead-painted wood windows cost more to handle.
• Weight-pocket insulation in old wood frames: $50-150 per window, a real energy upgrade.
• Trim, casing, and sill replacement: $50-200 per window when the old unit was a different size.
• Permits: $50-150; inspections required in many cities.
• Disposal: $25-100 per window for haul-away.

Ways to Save Money

• Choose insert (pocket) replacement over full-frame when the existing frame is sound; save 20-30% per window.
• Buy stock sizes; custom double-hungs add 30-50% and 2-4 weeks of lead time.
• Standardize on one glass package for the whole house; mixed packages confuse pricing and reduce volume discounts.
• Replace in volume; per-window price drops 10-20% on whole-home jobs.
• Claim the federal tax credit and any manufacturer rebates ($50-150 per window in seasonal promos).

DIY vs. Hiring a Professional

Insert replacement of a same-size double-hung in good trim is the most DIY-friendly window job, and a skilled homeowner can save $100-250 per window. But two factors push most buyers to pros: manufacturer warranties generally require professional installation, and flashing and sealing mistakes cause air leaks and water damage that void the energy savings. The hybrid: hire a pro for installs, DIY the interior trim, painting, and caulking, saving $50-150 per window without touching the weather barrier.

Sample Scenarios

• Single double-hung, stock vinyl, insert install: $400-600. The minimum viable replacement; good for a drafty bedroom window.
• 5-window bedroom wing, vinyl, low-E argon: $2,500-4,000 installed. Volume pricing brings the per-unit cost down 10-15%.
• 10-window whole home, vinyl, low-E argon: $6,000-11,000 installed; the value sweet spot for most homes.
• 10-window whole home, wood, historic district: $14,000-22,000 with period profiles and approval fees.

The pattern is consistent: frame material and glass package move the per-window number more than anything else, and volume moves the total. If your home has mixed window sizes, ask the contractor to quote stock sizes where possible; custom double-hungs add 30-50% and weeks of lead time for no functional gain.
