⚡ Quick Answer
Replacing a broken window pane costs an average of $284 per window, ranging from $150 for a small single pane to $500+ for a double-pane IGU. The key decision: if only the glass is broken and the frame is solid, you can replace just the pane — no need for a full window replacement. Full window replacement ($300–$700 installed) is only necessary when the frame is also damaged or the window is 20+ years old.
⚠️ Pane replacement vs. full window replacement — know the difference. If your glass cracked from an impact (ball, rock, storm debris), you likely need pane replacement only ($150–$500). If your window is fogging due to a failed seal, that's an IGU or seal issue — see our Double Pane Window Repair guide. Don't let a contractor upsell you to a full window replacement for a broken pane in a sound frame.

Estimated Glass Replacement Cost
Window Glass Replacement Cost by Glass Type
| Glass Type | Material Cost | Installed (per pane) | Notes |
|---|---|---|---|
| Single pane (basic float) | $3–$6/sq ft | $150–$400 | Cheapest option. Poor insulation. Common in older homes and storm windows. |
| Double pane IGU | $8–$15/sq ft | $200–$500 | Standard in most homes built after 1990. Must replace full IGU unit, not individual panes. |
| Triple pane IGU | $15–$25/sq ft | $400–$900 | Best insulation. Heavier — frame must be able to support added weight. |
| Tempered / safety glass | $12–$20/sq ft | $250–$600 | Required by code near doors, floors, bathrooms. Breaks into small pebbles instead of shards. |
| Low-E coated | $10–$20/sq ft | $280–$650 | Reflects infrared/UV. Reduces energy bills 7–15%. Common upgrade from basic double pane. |
| Laminated / impact-resistant | $20–$40/sq ft | $400–$900 | Stays in frame when broken. Required in hurricane zones. Security benefit for all climates. |
| Obscure / privacy glass | $10–$18/sq ft | $200–$550 | Frosted, patterned, or textured. Common for bathrooms and side panels at entry doors. |

Replace Just the Pane vs. Replace the Whole Window
- Replace the pane when: The frame is solid and square, the glass is the only damaged component, the window is under 15 years old, and repair cost is under 60% of a full replacement quote
- Replace the full window when: The frame is rotted, warped, or structurally compromised; multiple panes failing in the same window; the window is 20+ years old with outdated technology; or when you want to upgrade to impact-resistant or higher-efficiency glass
- Important for double pane: You cannot replace just one pane of an IGU — both glass layers plus the spacer and gas fill are a single factory-sealed unit. You replace the full IGU (not the whole window frame, but the full glass assembly)
When Replacing: Glass Upgrades Worth Considering
If you're already replacing the pane, upgrading the glass type costs relatively little extra and pays back in energy savings or safety:
- Low-E coating: Adds $50–$100 to pane cost; reduces cooling/heating costs 7–15% annually. Worth it for any south or west-facing window.
- Argon fill (double pane): Most quality IGUs include argon standard. Adds minimal cost, meaningfully improves R-value over air-filled units.
- Tempered glass: Required by code in many locations for glass near doors, floors, and bathrooms. Only modest cost premium over standard glass.
- Laminated glass: Stays in frame when broken — no dangerous shard scatter. Adds noise reduction as a bonus. Worthwhile on ground-floor windows in any climate.
💡 Custom-ordered glass lead times. Standard sizes ship in 1–3 days from local glass shops or big-box stores. Custom-cut glass for non-standard openings requires 2–6 weeks for fabrication. If your window has an unusual dimension, board it up temporarily and don't rush a contractor into using the wrong size — a poorly fitting pane leads to seal failure and repeat problems.

Fogging between panes? That's a different repair.
Foggy windows with moisture between panes are a seal/IGU failure — not a broken pane issue. See Double Pane Window Repair Cost → for the correct fix. In hurricane zones, consider upgrading to Impact Windows → while you're replacing.
Frequently Asked Questions
How much does it cost to replace window glass?
The national average is $284 per window for glass replacement. A small single pane runs $150–$400. A double-pane IGU costs $200–$500. Bay windows, skylights, and oversized panes cost significantly more — $600–$2,000+. Labor runs $50–$125/hour; most replacements take 1–2 hours.
Can I replace just the glass without replacing the whole window?
Yes — as long as the window frame is solid, square, and undamaged. A glazier can replace just the glass pane or IGU while keeping your existing frame. This typically costs 40–60% less than a full window replacement. The frame only needs replacement if it's rotted, warped, or structurally compromised.
Can I replace a single pane of a double pane window?
No. A double-pane window consists of two glass layers factory-sealed together as a single unit (IGU — Insulated Glass Unit) with argon or krypton gas between them. If one layer cracks, the entire IGU must be replaced as a unit. You cannot replace just one layer independently and maintain the window's insulating properties.
Does homeowners insurance cover window glass replacement?
It depends on the cause. If a storm, tree limb, hail, or vandalism broke the window, your homeowners policy (under dwelling coverage or additional glass coverage) may cover it. Normal wear and age-related cracking are not covered. Check your deductible before filing — if the replacement cost is close to your deductible, paying out-of-pocket avoids a rate increase.
How long does window glass replacement take?
Standard single or double-pane replacements take 1–2 hours for a glazier. Custom-ordered glass for non-standard sizes requires 2–6 weeks of fabrication time before installation. Bay windows and skylights take 3–4 hours due to complexity. For broken windows open to the elements, most glaziers offer same-day emergency service at a 1.5–2x labor premium.
