Window replacement cost in 2026 — by type, size, and material

Window replacement is one of the most searched home improvement topics — and for good reason. In 2026, replacing a window runs $300 to $1,200 per window installed depending on type, size, and frame material. Here are real prices from current projects, plus what actually drives the cost.

Window replacement cost by type (installed, mid-grade)

• Double-hung (most common) — $350 to $750 per window
• Single-hung — $300 to $600 per window
• Casement (crank-out) — $400 to $900 per window
• Sliding window — $350 to $700 per window
• Awning window — $400 to $800 per window
• Picture window (fixed) — $300 to $700 per window
• Bay window — $1,200 to $3,500 installed
• Bow window — $1,500 to $4,000 installed
• Garden window — $1,000 to $2,500 installed
• Skylight — $900 to $2,500 installed
• Egress window (basement) — $1,500 to $4,000 installed

Cost by frame material

• Vinyl — $300 to $700 / window. Low maintenance, best value. Dominant in 2026.
• Fiberglass — $500 to $1,200 / window. Stronger, better insulator, longer lifespan.
• Wood — $700 to $1,500 / window. Best aesthetics, needs regular maintenance.
• Aluminum — $400 to $900 / window. Durable but poor insulation (avoid in cold climates).
• Composite (wood + vinyl core) — $600 to $1,300 / window. Best of both worlds.

Full home replacement cost examples

(vinyl double-hung, standard sizes, labor included)

• 10 windows — $4,500 to $8,500
• 15 windows — $6,500 to $12,500
• 20 windows — $8,500 to $16,500
• 25 windows — $10,000 to $20,000

Note: replacing all windows at once saves 15-20% vs. doing them one at a time — crews mobilize once, labor per window drops.

Glass packages and what they cost

The frame is half the story. Glass package adds $50-$400 per window:

• Double-pane (standard) — base price, U-factor ~0.30
• Low-E coating — +$50-$100. Blocks UV, reduces heat gain. Required for Energy Star.
• Triple-pane — +$100-$250. Better insulation, worth it in Zone 5-7 climates.
• Argon or krypton fill — +$30-$80. Improves insulation by 15-20%.
• Laminated / impact glass — +$150-$400. Required in hurricane zones (FL, TX coast).
• Obscure / privacy glass — +$40-$80 (bathrooms).

What drives cost beyond window type

1. Window size — oversized or custom shapes cost 30-60% more
2. Installation method — insert (pocket) vs. full-frame replacement. Full-frame adds $100-$200/window but is necessary if frames or sills are rotted
3. Accessibility — second-floor windows need ladders or staging (+$50-$150/window)
4. Interior/exterior trim work — if replaced, add $80-$200/window
5. Number of windows — volume discount kicks in at 5+ windows
6. Brand — Andersen, Pella, and Marvin carry 20-40% premium over mid-grade brands

Tax credits for window replacement in 2026

The Inflation Reduction Act (25C) provides a 30% tax credit, up to $600 per year for Energy Star certified windows. Requirements:

• U-factor ≤ 0.30 (most double-pane Low-E qualify)
• Solar heat gain coefficient (SHGC) requirements vary by climate zone
• Applies to primary residence only

On a 15-window job at $9,000 total, that's potentially $600 back — always worth asking your contractor for Energy Star-certified options.

Signs you need replacement vs. repair

• Foggy between panes — seal failed, insulating gas gone. Replace the IGU or full window.
• Drafts around frame — could be weatherstripping ($20-$80/window) or failed frame seal
• Won't open/close properly — balance issues on double-hung ($50-$150 repair) vs. frame warp (replace)
• Visible rot or water damage — replace, not repair
• Single-pane glass — no repair makes sense, always replace

How to get an accurate window replacement quote

Every window in your home is slightly different. Measure rough opening width × height for each. Note the type, current frame material, and any custom shapes. The more detail you give a contractor, the more accurate the quote.

Use the ConstruMate window calculator to generate an itemized quote — by window count, type, and frame material — in under 5 minutes.

FAQ

How long does window replacement take? 30-60 minutes per window for an experienced crew. A 15-window house is typically a 1-2 day job.

Should I replace all windows at once? If more than 5-6 need replacement, yes — labor savings and warranty alignment make it worth doing together.

Vinyl vs. fiberglass — which is better? Vinyl wins on price and maintenance. Fiberglass wins on strength, insulation, and lifespan (40+ years vs. 20-30 for vinyl).
