Average Window Replacement Cost per Window: Real 2026 Prices by Type and Size
If you’re budgeting for new windows, the average window replacement cost per window is the number that matters most, because almost every contractor quotes the job per opening, not as a single lump sum. In 2026, most homeowners pay between $300 and $1,200 per window installed, with a nationwide average that usually lands around $650 to $750 for a standard double-hung unit. The spread is wide because window pricing depends on material, glass package, the size and shape of the opening, and how much labor your region charges.
That range matters more than the headline average. A stock vinyl double-hung in a standard 24-inch-by-36-inch opening can run $300 to $500 installed, while a large fiberglass or wood casement with triple-pane glass and a custom trim package can easily hit $1,500 to $2,500 per window. Understanding what drives the per-window number helps you read quotes accurately and avoid paying premium prices for standard work.
What Makes Up the Per-Window Price
Every window bid is built from three components: the window itself, installation labor, and any extras the job requires. When a contractor gives you a per-window figure, all three are usually already bundled in, which is why shopping on window price alone can be misleading.
The Window Itself
Materials set the floor for any bid. Vinyl windows are the cheapest, typically $150 to $700 for the unit before labor, and they dominate the replacement market in the US because they’re durable, low-maintenance, and energy-efficient for the price. Wood windows run $300 to $1,300 or more and carry real aesthetic value, but they need painting or sealing over time. Fiberglass and composite windows sit in the middle to high end, often $500 to $1,500, and they handle extreme temperatures better than vinyl. Aluminum is cheap and strong but conducts heat, so it performs poorly in cold climates and is now mostly limited to specific regions or commercial-style openings.
Installation Labor
Labor is the second cost driver and typically runs $100 to $300 per window for a straightforward replacement that fits the existing rough opening. Full-frame replacements — where the old frame, trim, and sometimes siding come out — cost more, often adding $50 to $150 per window on top of a standard retrofit. Jobs on upper floors, windows with rotted framing underneath, or homes with lead paint that requires special handling all push labor higher.
Glass and Efficiency Upgrades
The glass package changes the per-window cost faster than most people expect. A basic double-pane window with low-E coating and argon gas is now standard and usually included in the baseline. Triple-pane glass adds 10% to 15%. Impact-rated glass for coastal or hurricane-prone areas can add 25% to 50%. If you want gas fills, upgraded spacers, or a specific solar heat gain rating for a south-facing wall, expect the extras to show up as a line item.
Per-Window Costs by Material
The material you choose is the single biggest lever on the average window replacement cost per window, so it’s worth a close look before you start getting bids.
| Factor | Vinyl | Wood | Fiberglass |
|---|---|---|---|
| Typical unit cost | $150–$700 | $300–$1,300 | $500–$1,500 |
| Installed cost per window | $300–$1,000 | $600–$1,900 | $700–$1,800 |
| Maintenance | Low | Moderate to high | Low |
| Best for | Budget replacements | Historic or high-end homes | Extreme climates |
Vinyl
Vinyl is the default answer for most homeowners. It never needs painting, resists moisture, and the manufacturing quality has improved dramatically in the past decade. The trade-off is limited color options — you’re mostly choosing among white, tan, and a handful of earth tones — and slightly chunkier frames that reduce visible glass area compared to wood.
Wood
Wood windows are the premium choice for older homes and architectural styles where authentic millwork matters. They can be stained or painted to match existing trim exactly, which is why historic districts often mandate them. The running cost is higher than the purchase price: wood expands and contracts with humidity, so expect periodic scraping, sealing, or repainting every few years, especially on moisture-heavy exposures.
Fiberglass and Composite
Fiberglass frames expand and contract at nearly the same rate as the glass they hold, which makes them unusually stable and long-lasting. They’re a strong pick in climates with harsh seasonal swings, from Minnesota winters to Arizona summers. Composite windows blend wood fiber and resin, offering a wood-like look with far less upkeep. Both sit at the top of the price range, but their longevity often justifies the premium when you plan to stay in the home.
How Window Size and Shape Change the Price
Rate aside, the physical opening is what actually moves your per-window quote. Standard double-hung and slider windows are the cheapest because manufacturers produce them at scale. Anything custom costs more.
Standard Sizes
A stock double-hung window in a common size — say 36 inches by 54 inches — is produced in volume, so the unit cost stays low. If your openings match standard dimensions, often the case in tract homes built after the 1960s, you’ll pay the low end of every price range in this article.
Oversized and Custom Shapes
Picture windows, bay and bow windows, arched or radius-top windows, and anything with unusual dimensions are made to order, and the price reflects it. A large picture window can run $500 to $1,300 installed, while a full bay or bow assembly — which is really three or more windows working together — typically runs $1,800 to $4,500 or more as a unit. Egress windows in basements, which must meet code for size and hardware, also cost more than a same-size regular window.
Whole-House Volume
There’s a real economy of scale in window replacement. Replacing ten or more windows in one project usually earns a meaningful per-window discount because the crew sets up once and works efficiently. Many contractors will drop their per-opening rate by 10% to 20% on a whole-house job, and some manufacturers run seasonal promotions that cut material costs further.
The Labor Side: What Installers Actually Charge
Labor is where quotes diverge, and it’s the part of the average window replacement cost per window you have the most control over through comparison shopping.
A professional crew replaces a standard window in 30 to 60 minutes, but you’re not paying for the hour — you’re paying for the expertise of a tight, weather-sealed, plumb-and-level install. Poor installation is the leading cause of air leaks, moisture damage, and premature window failure, so this is not the line item to cut corners on.
Replacement style drives labor cost. A pocket replacement, where the new window slides into the existing frame, is the cheapest to install and works when the surrounding frame is sound. A full-frame replacement is more expensive but gives the installer a chance to inspect and repair any hidden rot, add flashing, and correct out-of-square openings — worth the extra money on older homes.
If you’re comparing bids from several companies, note how other homeowners break down per-window installer pricing in our separate guide on how much window installers make per window, which explains why labor quotes range as widely as they do from one shop to the next.
Average Costs by Window Type
Different window styles carry different default prices because of their opening mechanisms and hardware.
- Double-hung: $300 to $900 per window installed. The most common and the least expensive style to replace because openings are standardized.
- Casement: $450 to $1,200. Crank-operated, tight-sealing, and popular for kitchens and hard-to-reach spots.
- Sliding: $350 to $900. Inexpensive and easy, though their tracks need occasional cleaning to glide well.
- Picture: $400 to $1,400. The glass is affordable per square foot, but larger fixed units run high simply because of size.
- Bay or bow: $1,800 to $4,500 as a complete assembly. A structural addition to the home more than a single window swap.
How to Get an Accurate Quote
Because the average window replacement cost per window varies so much by region and project, the only number that counts is the one on your own written estimate. Get at least three quotes, and give each contractor the same information so the comparison is fair.
- Specify window-by-window. Ask for a line-item bid that lists each opening, its size, the material, and the glass package. A single aggregated number hides variances.
- Ask what’s included. Confirm whether the price covers haul-away of the old windows, interior and exterior trim, and any permitting or inspection fees your municipality requires.
- Check the warranty. Labor warranties vary widely. A company that warranties its install for 10 years or more is worth a modest premium.
- Don’t buy on gimmicks. Door-to-door outfits that pitch a “today only” discount often start with an inflated list price. Take overnight to compare.

Frequently Asked Questions
How much does it cost to replace one window?
A single standard window replacement typically costs $300 to $1,200 installed, with most homeowners landing around $650. Small vinyl openings sit at the low end, while large wood or fiberglass windows run higher.
Is it cheaper to replace all windows at once?
Usually, yes. Replacing ten or more windows in a single project often cuts 10% to 20% off the per-window rate because the crew sets up once and manufacturers may offer volume or promotional pricing.
Do window prices include installation?
In most contractor bids, yes — the per-window figure bundles the unit, standard labor, and basic trim. Always confirm in writing, since some window manufacturers quote product only and leave installation to a separate contractor.
What is the cheapest type of replacement window?
Stock vinyl double-hung and sliding windows are the least expensive, often $300 to $500 installed for standard sizes. They cost less up front and carry low maintenance, though they offer fewer design options than wood.
How long does window replacement take?
A crew typically replaces 10 to 15 windows in a single day for standard pocket replacements. Individual windows take under an hour each once the crew is set up; full-frame replacements with trim work take longer per opening.
The Bottom Line
The average window replacement cost per window sits around $300 to $1,200 installed in 2026, with material, glass package, and window size doing most of the work in setting your specific price. Vinyl double-hungs in standard openings deliver the lowest cost, while wood, fiberglass, and custom shapes run higher for good reason.
Get three written, line-item bids, confirm what each one includes, and don’t let a high-pressure sales pitch rush you. Windows are a two-to-three-decade purchase, and a few hundred dollars more for a better install from a reputable installer is almost always money well spent.
