How Much Does Window Replacement Cost in 2026?
Most homeowners spend about $600 to $1,200 per window to replace standard double-hung windows, installed — the 2026 national average lands near $1,000 per window including both the unit and labor. A full-home replacement of 10 to 15 windows typically runs $8,000 to $18,000, though budget vinyl jobs can come in lower and premium wood or fiberglass higher.
Two choices drive most of the price: frame material and window style. Aluminum and vinyl frames are the affordable end; fiberglass is mid-range; wood is premium. On top of that, the window style matters — a casement or awning costs a bit more than a standard double-hung, and a bay or bow window can cost two to three times as much because it's really several windows in one unit. The calculator above lets you set both, plus your region.
Industry data shows the window units themselves make up the bulk of the cost — often around 85% — with labor making up the rest. Treat the result as a budgeting estimate, not a quote: old-window condition is a wildcard, and rotted sills or non-standard openings can raise the price once an installer inspects the job.
Window replacement cost by frame material (installed, 2026)
| Frame material | Per window | Full home (12 windows) |
|---|---|---|
| Aluminum (budget) | $300 – $800 | $3,600 – $9,600 |
| Vinyl (standard) | $450 – $1,050 | $5,400 – $12,600 |
| Fiberglass | $700 – $1,500 | $8,400 – $18,000 |
| Wood (premium) | $800 – $1,800 | $9,600 – $21,600 |
Installed costs for standard double-hung windows at the National average region (2026). Premium brands and large or custom windows run higher. Northeast and West run ~20–25% above; Midwest ~10% below.
Window replacement cost by style (vinyl, installed)
| Window style | Per window (vinyl) | Notes |
|---|---|---|
| Single-hung | $300 – $900 | Only the bottom sash opens — the most budget-friendly |
| Double-hung | $450 – $1,050 | Both sashes open; the most common style |
| Sliding | $400 – $1,000 | Opens side to side; good for wide openings |
| Picture / fixed | $475 – $1,100 | Does not open; large glass area |
| Awning | $520 – $1,200 | Hinged at the top; good for ventilation in rain |
| Casement | $540 – $1,260 | Crank-out; strong seal and energy efficiency |
| Bay | $1,000 – $2,300 | Three-panel projection; priced as one larger unit |
| Bow | $1,200 – $2,700 | Four-plus panel curved projection |
Vinyl frame, installed, National average region. Other materials scale up from these figures (fiberglass ~1.45×, wood ~1.75×).
What Drives Window Replacement Cost
Two homes with the same number of windows can pay very different amounts. The biggest factors:
| Factor | Effect on cost | Notes |
|---|---|---|
| Frame material | Largest single factor | Aluminum/vinyl cheapest; fiberglass and wood are premium. |
| Window style | High | Double-hung and sliders are standard; bay, bow, and custom shapes cost much more. |
| Installation type | High | Insert (retrofit) is cheaper; full-frame replacement removes the old frame and costs more. |
| Glass package | Moderate | Triple-pane, low-E coatings, and gas fill add roughly $50–$200+ per window. |
| Frame / sill repair | Variable | Rotted sills or non-standard openings add labor and custom sizing. |
| Number of windows | Discount | Replacing many at once usually lowers the per-window price. |
For an accurate number, ask whether a quote is for insert or full-frame replacement — that single choice can change the total by thousands.
Glass and Energy-Efficiency Options
The glass package is an easy upgrade to overlook, but it affects both price and long-term value. Double-pane is the modern standard; triple-pane adds insulation for cold climates or noise reduction, typically adding $50–$200 per window. Low-emissivity (low-E) coatings reflect heat, and argon or krypton gas fill between panes improves insulation further.
Energy-efficient windows cost more upfront but lower heating and cooling bills, and ENERGY STAR-rated products may qualify for federal energy tax credits or local utility rebates. If you live somewhere with temperature extremes, the efficiency upgrade often pays back over time — weigh the higher initial cost against the energy savings and any available incentives.
Real-world cost examples
| Scenario | Windows | Material | Style | Estimated total |
|---|---|---|---|---|
| Small home refresh | 8 | Vinyl | Double-hung | $3,600 – $8,400 |
| Typical full-home | 12 | Vinyl | Double-hung | $5,400 – $12,600 |
| Premium upgrade | 15 | Fiberglass | Casement | $14,700 – $34,200 |
Each example uses the National average region and the same model as the calculator above. Your real cost depends on glass package, installation type, and frame condition — always confirm with on-site quotes.

Frequently Asked Questions
How much does it cost to replace 10 windows?
In 2026, replacing 10 standard vinyl double-hung windows typically runs about $4,500 to $10,500 installed nationally, or roughly $600–$1,000 per window. Fiberglass and wood cost more; budget aluminum costs less; and styles like bay or bow cost significantly more. Replacing all 10 at once usually earns a per-window discount.
How does window style affect the price?
Style is a major cost driver after material. Single-hung and sliding windows are the most affordable; double-hung is the common baseline; casement and awning cost a bit more for their hardware and seal; and bay or bow windows cost two to three times as much because each is really several windows combined into one projecting unit.
Is it cheaper to replace all windows at once?
Usually yes. Installers often discount the per-window price on larger jobs because the crew, setup, and disposal are already mobilized. If your budget allows, doing the whole home at once typically costs less per window than replacing a few at a time.
What is the most affordable window material?
Vinyl is the most popular affordable option, balancing low cost, good energy efficiency, and minimal maintenance. Aluminum can be cheaper still but insulates less well. Fiberglass and wood cost more upfront but offer better durability, efficiency, or appearance.
What is the difference between insert and full-frame replacement?
Insert (or retrofit) replacement fits a new window into your existing frame — faster and cheaper. Full-frame replacement removes the entire old frame down to the studs, which is more expensive but necessary if the frame is rotted or you're changing the window size. Always confirm which type a quote covers.
Do new windows qualify for tax credits or rebates?
Energy-efficient windows may qualify for federal energy tax credits and some utility or state rebates, depending on the product's efficiency rating and current programs. Check the window's ENERGY STAR rating and the latest federal and local incentives before purchasing, as program details change.
Does replacing windows add home value?
Yes. New windows typically recover a meaningful share of their cost at resale and improve curb appeal and energy efficiency. Industry cost-vs-value reports consistently show window replacement returning a large portion of its cost, though it's primarily a functional and efficiency upgrade rather than a profit-generating one.
Should I repair or replace my windows?
Repair makes sense for minor issues like a broken seal, faulty hardware, or a single damaged pane on an otherwise sound window. Replace when frames are rotted or warped, windows are single-pane and inefficient, or repairs are becoming frequent. A professional assessment will tell you which is more economical.
