Most homeowners pay $200–$650 per window to replace broken or fogged glass, with typical jobs averaging $285–$475. A sealed double-pane unit costs $300–$900 installed (Angi, HomeGuide and HomeAdvisor data, as of October 2026).

Glass-only replacement makes sense when the frame and sash are still solid but a pane is cracked, shattered or fogged between the layers because the seal failed. The installer swaps the single pane or the whole insulated glass unit (IGU) and reuses the existing frame, which is why it typically costs about 30% to 70% less than a new window.
This guide covers average prices per window, the line items on a typical bill, what pushes the price up, and when it's smarter to replace the whole unit instead. If your frames are rotten or drafty, compare these figures with our full window replacement cost guide.
Average cost
Installed prices per window for glass-only replacement, national averages as of October 2026:
| Scenario | Typical range | Notes |
|---|---|---|
| Small single-pane glass, standard size | $150–$400 | Float glass cut to size; often under an hour of labor |
| Mid-size double-pane insulated unit (IGU) | $300–$800 | Most common job: fogged or cracked sealed unit |
| Large, picture or specialty glass (tempered, low-E, triple-pane) | $600–$1,200+ | Custom order; large picture panes can exceed $2,000 |
Cost by glass type
Installed price per window by glass type (ranges blended from Angi and HomeGuide):
| Glass type | Cost per window installed | Where it's used |
|---|---|---|
| Float (standard annealed) | $150–$500 | Basic single-pane windows, storm sashes |
| Tempered | $200–$750 | Required near doors, tubs, floors and in large panes |
| Laminated | $300–$750 | Security and noise reduction |
| Low-E coated | $300–$1,000 | Energy-efficient insulated units |
| Argon-filled IGU | $400–$900 | Standard insulated glass upgrade |
| Krypton-filled IGU | $450–$1,200 | Thin triple-pane units |
| Frosted / obscure | $300–$800 | Bathrooms, privacy windows |
Cost by glass size
| Pane size | Cost per window installed |
|---|---|
| Small (under 24" × 24") | $150–$350 |
| Medium (24" × 36" to 30" × 48") | $350–$600 |
| Large (48" × 60" or larger) | $600–$1,200+ |
| Extra-large / picture | $1,200–$2,800+ |
Cost breakdown: materials, labor, permits and extras
Line-item estimate for replacing one fogged, mid-size double-pane insulated glass unit in a first-floor vinyl window. Ranges are national, as of October 8, 2026.
| Cost item | Typical range | What it covers |
|---|---|---|
| Glass unit (materials) | $120–$350 | Custom-made sealed double-pane unit, low-E where specified |
| Labor | $50–$200 | Measuring trip, removing stops, setting the new unit; about 1–3 hours |
| Glazing supplies | $10–$40 | Setting blocks, glazing tape, sealant, replacement beads |
| Removal & disposal | $0–$50 | Often included; some glaziers bill $50–$100 |
| Contingency (about 10%) | $20–$60 | Damaged stops or a second trip if the unit arrives wrong |
| Estimated total | $200–$700 | Before any discounts or rebates |
Labor makes up roughly 30% to 60% of a glass-only bill, so replacing several panes in one visit lowers the cost per window.
What affects the price
- Single pane or insulated glass unit. A single pane of float glass costs about $150–$400 to replace, while a sealed double-pane insulated unit runs $300–$900 and triple-pane $400–$1,200, because the whole unit has to be built to size.
- Size. Small panes under 24" × 24" cost about $150–$350; large panes over 48" × 60" run $600–$1,200 or more, and oversized picture glass can top $2,800.
- Special glass (tempered, low-E). Tempered glass (required by code near doors and tubs) costs about $200–$750 installed, and tempering a large pane can add $100–$300. Low-E coatings put a unit at roughly $300–$1,000.
- Condition of the frame. If the sash or frame is rotted or warped, frame repair adds about $150–$1,000. At that point a full double-pane window replacement is often the better value.
- Labor. Glaziers charge about $50–$125 per hour, and most panes take 1–3 hours. Second- or third-story windows add $150–$400, emergency calls cost 50% to 100% more, and many shops have a $100–$150 minimum.
Ways to save
- Check the warranty first: many manufacturers cover failed seals (fogging) on insulated units for 10–20 years, which can make the glass free or discounted.
- Bundle every cracked or fogged pane into one appointment; the trip and setup cost is spread over more windows, and many glaziers have a $100–$150 minimum anyway.
- Ask for the glass unit only (not a new sash) when the frame is sound. Glass-only work typically saves 30% to 70% compared with a full window replacement.
- Avoid emergency service when you can board up or tape the opening safely for a few days; after-hours calls cost 50% to 100% more.
- Stick with standard double-pane low-E glass instead of krypton or triple-pane unless you live in a very cold climate; specialty fills can add several hundred dollars per unit.
Related questions people ask
How much does double pane window glass replacement cost?
Replacing a sealed double-pane glass unit costs about $300–$900 per window installed, depending on size and coatings. A standard mid-size argon-filled low-E unit usually lands in the $400–$600 range. You're buying a new factory-sealed unit, not just a sheet of glass, which is why it costs roughly twice as much as single-pane glass.
How to get an accurate quote
Get at least three written quotes from local glass shops or window installers. Give each one the same details:
- The exact glass size (width × height of the visible glass and the full unit) and whether it's single pane or a sealed double/triple-pane unit.
- The brand of the window and any label or code etched in the corner of the glass, which tells the glazier the unit's specs and whether it's still under warranty.
- Whether the glass must be tempered, low-E, laminated or obscure, and which floor the window is on.
- Ask whether the quote includes the measuring visit, disposal of the old glass, and a warranty on both the seal and the labor.
FAQ
Is it cheaper to replace the glass or the whole window?
Replacing only the glass is usually 30% to 70% cheaper. Expect $200–$650 for glass versus about $450–$1,500 for a full replacement window. If the frame is rotten or the window is drafty, a full replacement is the better long-term buy.
Can fogged double-pane glass be fixed without replacing it?
Some companies offer defogging or resealing, but results vary and the insulating gas is usually gone for good. Replacing the sealed unit, at roughly $300–$900, is the standard fix.
How long does window glass replacement take?
The installation itself usually takes 1–3 hours per window. Custom insulated units are made to order, so plan on a measuring visit and a wait of one to a few weeks before the install.
