Window Replacement Cost
National planning ranges, installed, September 2026: $450–$1,200 per vinyl window, $6,000–$20,000+ for a typical whole house. Wood and fiberglass, full-frame installs and big openings push it higher. Here is what moves the number.
Standard vinyl double-hung, insert install, per window, September 2026
$450 – $1,200
Whole house, 10–15 windows: $6,000–$20,000 in vinyl, $15,000–$35,000+ in fiberglass, wood or full-frame.
Window pricing is quoted per opening, and the published data agrees on the middle. Fixr's 2026 figures put a replacement at $450–$1,200 per window (average about $800, outliers $300–$3,000) and HomeAdvisor's normal range is $300–$2,100, with installer pricing clustering a vinyl double-hung near $650 and fiberglass near $850. The whole-house number is that per-window price times your count, minus a volume discount most companies give if asked.
Cost per window by frame and install type
| Item | Range | Notes |
|---|---|---|
| Vinyl double-hung, insert | $450 – $1,200 | The benchmark. Lowest cost, no painting, 20–30 year life. Limited colors and can warp in dark finishes in hot climates |
| Fiberglass or composite, insert | $700 – $1,800 | Stiffer and paintable, expands at the same rate as glass so seals last longer. Roughly 30% over vinyl |
| Wood or clad wood, insert | $900 – $2,500+ | Best looks, exterior aluminum or fiberglass cladding cuts upkeep. Historic districts often require it |
| Full-frame replacement, any material | +50 – 100% | Removes the whole unit to the rough opening and re-flashes it. Needed when the frame is rotted or you want a bigger glass area |
| Glass upgrades | +$50 – $300 per window | Triple pane, argon or krypton fill, laminated or tempered, higher-spec low-E for hot or cold climates |
| Bay, bow, picture or custom shapes | $1,500 – $5,000+ | Bay and bow units add roof, seat and support work |
| Whole house, 10–15 windows, vinyl | $6,000 – $20,000 | The 2025 Cost vs Value benchmark (ten 3 x 5 ft vinyl double-hungs) averaged about $20,000 nationally |
What drives the price
| Driver | Impact | Notes |
|---|---|---|
| Frame material | 2–3x swing | Bigger lever than window style. Vinyl base, fiberglass about 1.3x, clad wood 2x or more |
| Insert vs full-frame | +50–100% for full-frame | Inserts keep the old frame and lose an inch or two of glass. Full-frame is the honest fix for rot and leaks |
| Window style | Casement and sliders +10–30% over double-hung | More hardware, larger single panes. Picture windows are cheapest per square foot of glass |
| Size and count | Linear, with a volume discount | Oversize units need two installers and sometimes a lift. Whole-house jobs typically earn 10–20% off per window |
| Second story and access | +$50 – $150 per window | Ladders, scaffolding or interior-only installs |
| Trim, siding and interior finish | +$100 – $400 per window | Full-frame jobs need new exterior trim and interior casing; stucco and brick cost more to patch |
| Brand and sales channel | Up to 2x | Direct-sales national brands with in-home presentations often quote double what a local installer charges for a comparable ENERGY STAR window |
| Region and season | ±20–30% | Coastal metros run highest. Late fall and winter bids are often softer |
Energy savings: real but slow
ENERGY STAR's modeling for a typical two-story home puts the savings from replacing single-pane windows with certified units at roughly $490–$570 a year by climate zone, about 11–13% of the whole-home bill; replacing clear double-pane saves about $250–$370. Against a $15,000 job, the payback on energy alone runs 25 years or more. Buy new windows for comfort, drafts, noise, rot and sashes that no longer open, and treat utility savings as a bonus. The federal 25C credit (up to $600 a year on windows) ended for installs after December 31, 2025, per the IRS, so look for utility rebates instead.
Resale value
The 2025 Remodeling Cost vs Value report from Zonda and JLC put vinyl window replacement at roughly 68% of cost recouped nationally and wood at about 61%, on projects averaging around $20,000 and $26,000 respectively. That is mid-pack: well behind a garage door but ahead of most interior remodels, and a house with rotting or painted-shut windows is a hard sell.
DIY vs pro
An insert window in a square, sound wood frame is a doable DIY project, saving roughly $150–$350 per window in labor. The risk is the measurement: replacement windows are made to order, and a unit ordered a half-inch wrong is not returnable.
Full-frame replacements, upper-story windows, brick or stucco, and any job with rot should go to a pro. Flashing and sill-pan detailing keeps water out of the wall for 20 years, and most warranties require certified installation for the full term. A two-person crew sets 8–12 insert windows a day, so a whole house is usually one to two days of disruption.
Quick answers
How much does window replacement cost per window in 2026?
As of September 2026, a standard vinyl double-hung insert runs roughly $450–$1,200 installed, with Fixr's national average near $800. Fiberglass and composite run about $700–$1,800, wood $900–$2,500+, and full-frame installation adds roughly 50–100% over an insert. Large, bay, bow or custom-shaped windows can pass $3,000 each.
How much does it cost to replace all the windows in a house?
A typical 10–15 window house runs about $6,000–$20,000 in vinyl inserts and $15,000–$35,000+ in fiberglass or wood, or full-frame. The 2025 Cost vs Value benchmark, ten 3-by-5-foot vinyl double-hungs, averaged roughly $20,000 nationally. Most installers discount 10–20% per window on whole-house jobs versus one or two at a time.
Do new windows pay for themselves in energy savings?
Not on energy alone. ENERGY STAR estimates replacing single-pane windows with certified ones saves roughly $490–$570 a year (up to about 13% of the bill) and replacing clear double-pane saves $250–$370. Against a $15,000 job that is a 25-year-plus payback. The stronger case is comfort, noise, rot and operability, and the 2025 Cost vs Value report's roughly 68% resale recovery for vinyl.
Before you sign: make sure the quote names the window series, the NFRC U-factor and SHGC, the install method and who fixes the trim. A window quote without those four is a price for something you have not chosen yet. See how to read a contractor quote.
