Window Glass Replacement Cost: $150–$880 per Window (Average $285) in 2026
Author: CostGuideHQ Editorial·✓ Fact-checked·Updated July 2026·7 min read·5 sources·US national averages, USD Quick answerQuick answer: Window glass replacement costs $150 to $880 per window, averaging $285 (HomeAdvisor). Single-pane runs $150 to $400, double-pane (IGU) $150 to $600 — including foggy-seal swaps — and triple-pane $400 to $950. It's typically far cheaper than a full window replacement.
- ✓Window glass replacement costs $150 to $880 per window installed, averaging $285 nationally (HomeAdvisor).
- ✓Single-pane glass runs $150 to $400 installed; a foggy double-pane window needs the same $150-$600 sealed-unit (IGU) swap as any double-pane glass replacement (Fixr, This Old House).
- ✓Specialty glass costs more before labor: tempered $180 to $700, laminated $275 to $625, argon-filled $375 to $850, krypton-filled $525 to $1,190 (Fixr, This Old House, Bob Vila).
- ✓A full window replacement averages $750 per window — well above the $300 to $880 installed cost of swapping just the glass (Bob Vila).

What affects the cost?
- Pane type — single-pane glass replacement runs $150-$400 installed, double-pane (IGU) $150-$600, and triple-pane $400-$950 (Fixr, This Old House)
- Foggy/failed double-pane units — a fogged or cloudy double-pane window means the sealed insulated glass unit (IGU) has failed, so the fix is swapping the whole sealed unit rather than a single pane, landing in the same $150-$600 installed range as any double-pane glass replacement (Fixr, This Old House)
- Specialty glass upgrades (material only, before labor) — tempered $180-$700, laminated $275-$625, Low-E coated $350-$840 (Fixr, This Old House, Bob Vila)
- Gas fills (material only, before labor) — argon-filled $375-$850, krypton-filled $525-$1,190 (Fixr, This Old House, Bob Vila)
- Pane size — material cost scales with glass area, from $130-$180 for a 24x36-inch pane up to $650-$810 for a 46x54-inch pane (Fixr, This Old House)
- Glass-only vs. full window replacement — new windows for a house average $750 per window, versus $300-$880 to replace just the glass with labor (Bob Vila)
- Labor rate — glazing labor runs $50-$125 per hour, with a single pane typically taking 45-60 minutes to swap (Fixr, This Old House, Bob Vila)
- Per-square-foot pricing — glass generally runs $3-$12 per square foot, with double-pane specifically $6-$12 per square foot (Bob Vila); commercial storefront glass runs about $5 per square foot standard or $25 per square foot tempered (Fixr)
How much does it cost to replace a window pane?
Expect to pay $150 to $880 per window installed, averaging $285 nationally (HomeAdvisor). Bob Vila’s figures track almost exactly — average $281, typical range $180 to $411 — since both sources blend cheap single-pane jobs in with pricier double- and triple-pane ones. Fixr and This Old House report a higher $375 average with the same $300 to $880 range, because that number specifically reflects the most common job: a standard 30x36-inch double-pane window. Broken out by pane count, single-pane glass runs $150 to $400 installed, double-pane $150 to $600, and triple-pane $400 to $950 (Fixr, This Old House). Size moves the material cost too — a small 24x36-inch pane runs $130 to $180, while a large 46x54-inch pane runs $650 to $810 (Fixr, This Old House), before labor is added. A straightforward single-pane swap can move fast: Daniel W., a Minneapolis homeowner whose kitchen window shattered in sub-zero cold, wrote that the technician “was friendly, professional, and able to get everything done in less than 30 minutes” (Angi).
Why does my double-pane window look foggy, and what does fixing it cost?
A cloudy, hazy, or foggy double-pane window almost always means the sealed insulated glass unit (IGU) between the two panes has failed. Double-pane and triple-pane windows rely on a hermetic seal to keep the gap between panes clear and, often, filled with insulating gas; once that seal breaks, moisture gets in and fogs the glass permanently from the inside — no amount of cleaning fixes it. The repair is the same job as any double-pane glass replacement: ordering a new IGU sized to your existing frame and swapping it in, priced at $150 to $600 installed (Fixr, This Old House). It isn’t a simple pane swap like a cracked single-pane window, since the two (or three) layers of glass, spacer, and seal all ship as one factory-sealed unit rather than individual sheets.
Is it cheaper to replace just the glass or the whole window?
Replacing just the glass is almost always cheaper, as long as the frame is still square and sound. A glass-only swap with labor runs $300 to $880 for a standard job (Fixr, This Old House), while Bob Vila reports that new windows for a house average $750 per window — well above what it costs to replace only the glass. The catch is that glass-only replacement only works when the frame, sash, and weatherstripping are still in good shape; if the frame is rotted, warped, or you’re changing the window’s size, you’re back to a full window replacement instead. If your window is specifically double-pane and you’re deciding between an IGU swap and a full double-pane window replacement, the same math applies — glass-only is the budget option when the frame doesn’t need to be touched.
What does upgraded or specialty glass cost?
Specialty glass adds cost on top of a standard clear pane, and these figures are for material only — glazing labor of $50 to $125 an hour (45 to 60 minutes per pane) gets added separately (Fixr, This Old House, Bob Vila). Tempered glass, which shatters into small, less-dangerous pieces and is often required near doors or floors, runs $180 to $700. Laminated glass, built with a plastic interlayer for extra security and sound dampening, runs $275 to $625. Gas fills that boost insulation cost more still: argon-filled glass runs $375 to $850, and krypton-filled glass — denser and better-insulating in a narrower gap — runs $525 to $1,190. Per square foot, glass generally runs $3 to $12, with double-pane specifically at $6 to $12 per square foot (Bob Vila); commercial storefront glass is priced on its own scale, around $5 per square foot for standard glass or $25 per square foot for tempered (Fixr). If you’re chasing privacy or heat control rather than a repair, window tinting is worth pricing separately — it’s a film applied to existing glass rather than a glass replacement.
Prices vary by region, glass type, and window size, so treat the figures above as a planning budget. Get two or three local quotes, and confirm whether the estimate is for the glass alone or includes new sash and frame components before comparing bids.

Frequently asked questions
How much does it cost to replace a window pane?+
Most homeowners pay $150 to $880 per window installed, averaging $285 nationally (HomeAdvisor). Bob Vila's figures land almost identically: average $281, typical range $180 to $411. Fixr and This Old House report a higher $375 average for a standard double-pane window specifically, with a $300 to $880 typical range.
How much does it cost to fix a foggy double-pane window?+
A cloudy or foggy double-pane window means the sealed insulated glass unit (IGU) has failed, letting moisture in between the panes. The fix is a full IGU swap, priced the same as any double-pane glass replacement: $150 to $600 installed (Fixr, This Old House).
Is it cheaper to replace just the glass instead of the whole window?+
Yes, by a wide margin. Glass-only replacement runs $300 to $880 installed for a standard job (Fixr, This Old House), while Bob Vila puts a full new window at $750 per window on average — well above what a glass-only swap costs when the frame is still sound.
What does tempered or laminated glass cost extra?+
Tempered glass runs $180 to $700 and laminated glass $275 to $625, both material only before labor (Fixr, This Old House, Bob Vila). Add glazing labor of $50 to $125 an hour on top.
How much does triple-pane glass replacement cost?+
Triple-pane glass runs $400 to $950 installed (Fixr, This Old House) — noticeably more than double-pane's $150 to $600, since there's an extra pane and gap to manufacture and seal.
How much does window glass cost per square foot?+
Glass generally runs $3 to $12 per square foot, with double-pane specifically at $6 to $12 per square foot (Bob Vila). Commercial storefront glass is priced differently — about $5 per square foot for standard glass or $25 per square foot for tempered (Fixr).
Why do window glass replacement estimates vary so much between sources?+
HomeAdvisor ($285 average) and Bob Vila ($281 average) both publish broad averages blending single-pane, double-pane, and specialty jobs together. Fixr and This Old House report a higher $375 average because that figure specifically reflects the most common case — a standard double-pane window — rather than a blend across all pane types.

Four dedicated window-glass-replacement pages were fetched, and they split into two clusters. HomeAdvisor (national average $285, range $181-$413) and Bob Vila (average $281, range $180-$411, extremes $100-$700) publish near-identical broad averages that blend single-pane, double-pane, and specialty jobs together. Fixr and This Old House both report a higher headline ($375 average, $300-$880 range) — both sources note $375 is specifically 'the most common cost for a standard 30x36 double-pane window,' so their headline leans on the double-pane case (the most common glass type in US housing stock) rather than a blend across all pane types. national_average_usd is anchored to HomeAdvisor's blended, verbatim average ($285). range_low_usd ($150) is the single-pane low all sources agree on; range_high_usd ($880) is Fixr/This Old House's typical-range ceiling, spanning a basic single-pane swap through a standard double- or triple-pane replacement. Specialty upgrades — gas fills, tempered/laminated glass, larger panes — push individual jobs above $880 into the $900-$1,200+ range; those live in the by_type table as upgrades rather than in the headline range. Specialty-glass and pane-size figures from Fixr, This Old House, and Bob Vila are explicitly stated as material only, with glazing labor ($50-$125/hour) added on top; the single-/double-/triple-pane headline figures are installed (materials + labor). HomeAdvisor's own by-pane-type breakdown runs a little higher on the double- and triple-pane end (double $300-$900, triple $400-$1,000) than Fixr/This Old House ($150-$600 / $400-$950) — likely reflecting different assumptions about frame prep or sash removal. This record covers glass-only repair — single-pane replacement, double-pane insulated glass unit (IGU) swaps for fogged or failed seals, and specialty glass — as distinct from replacing the entire window frame and sash: Bob Vila notes new windows for a house average $750 per window, well above the $300-$880 installed cost of a glass-only swap. Full frame-and-sash replacement is priced separately in window-replacement-cost.json and double-pane-window-replacement-cost.json.
