Window replacement cost runs about $450 to $1,500 per window installed in 2026, and most national averages land between $800 and $900. A 10-window house typically costs $4,500 to $15,000, or about $8,000 at an $800 average. Quotes swing mainly on retrofit vs full-frame installation, big-brand vs local installer, and frame material.
Prices updated September 2026.
Research window replacement cost online and you will see $517, $565, $800 and $1,600 per window, sometimes on one results page. None is wrong; they measure different things. Below we line them up, then break US prices down by type, material, size, install method and window count.
Average window replacement cost (per window & whole house)
For a standard-size, double-pane vinyl window swapped into an existing opening, plan on roughly $800 to $900 installed. Fixr puts the national average at $800 (typical range $450 to $1,200), HomeAdvisor at $850, and HomeGuide at $900 (range $450 to $1,500).
For a whole project, Angi’s data from 13,122 verified projects shows an average of $7,347, with most homeowners paying $3,436 to $11,837. Angi estimates a standard 3-bedroom home with 10 to 12 windows at $7,000 to $9,000. That works out to about $580 to $900 per window ($7,000 ÷ 12 and $9,000 ÷ 10).
Why online prices disagree ($517 vs $800 vs $1,600)
Here is every headline number from the top US results and what it actually measures.
| Number you’ll see | Who publishes it | What it measures | Why it differs |
|---|---|---|---|
| $517 per window | This Old House, 2026 survey of 1,000 window buyers | Average paid per installed window, self-reported | Blends every type, size and install method, including small, simple windows |
| $565 per window | Inch Calculator | Installed average | Page last updated September 2023, the oldest figure in the results |
| $800 per window | Fixr (Jan 2026) | National average installed; typical $450 to $1,200 | Standard-size, mid-range windows |
| $850 per window | HomeAdvisor (June 2026) | Average installed; range $300 to $2,100 | Broad mix of project types |
| $900 per window | HomeGuide (Feb 2026) | Installed $450 to $1,500; unit alone $250 to $1,400+ | Product plus labor |
| $800 to $1,600 per window | Pella (May 2026) | Vinyl windows installed by the manufacturer | Full-service brand pricing; fiberglass and wood run $1,100 to $2,200+ |
| $7,347 per project | Angi (Aug 2026), 13,122 projects | Whole job, not one window | Divide by your window count before comparing |
Four things explain nearly all of the spread:
- Install method. An insert (retrofit) window slides into the old frame; a full-frame job tears everything out to the studs. HomeAdvisor lists labor at $100 to $300 per window for retrofit vs $150 to $800 for full-frame.
- Product only vs installed. HomeGuide prices the window unit alone at $250 to $1,400+, but $450 to $1,500 installed. A store price tag is not a project price.
- Brand and sales model. Full-service national brands bundle the in-home sale, measuring, custom build, install and warranty into one price. Local installers usually quote a stock or dealer window plus labor.
- Material and window type. A vinyl single-hung and a wood bay window are both “a window,” but one can cost ten times the other.

Cost by window type
Hinges, cranks, extra sashes and projecting frames all add parts and labor, so operating style matters.
| Window type | Fixr (Jan 2026) | HomeGuide (Feb 2026) |
|---|---|---|
| Single-hung | $250–$700 | $300–$2,100 |
| Double-hung | $300–$1,000 | $350–$2,500 |
| Slider | not listed | $300–$2,300 |
| Picture | $300–$1,600 | $300–$1,300 |
| Casement | $400–$1,200 | $400–$3,000 |
| Awning | $300–$800 | $400–$2,000 |
| Bay | $900–$4,500 | $2,000–$6,000 |
| Bow | $1,500–$8,000 | $3,000–$8,000+ |
Below-grade openings work differently, especially where code requires an escape window. See our basement window guide for those prices.
Cost by frame material
| Frame | Fixr (Jan 2026) | HomeGuide (Feb 2026) | Pella, installed by Pella (May 2026) |
|---|---|---|---|
| Aluminum | $200–$800 | $175–$1,000 | not listed |
| Vinyl | $350–$800 | $200–$1,500 | $800–$1,600 |
| Fiberglass | $400–$1,500 | $400–$2,000 | $1,100–$2,200 |
| Composite | $300–$2,500 | $400–$2,300 | not listed |
| Wood | $600–$2,000 | $800–$3,800 | $1,100–$2,200+ |
Vinyl is the budget choice; fiberglass and wood cost more but take paint or stain. Note that Pella’s vinyl range starts where Fixr’s ends: that is the brand-and-service premium again.
Cost by window size
Bigger glass means more material and often an extra installer. HomeAdvisor groups prices into three bands; we added common sizes so you can match your windows.
| Size band | Example sizes (W x H) | Area | Price per window |
|---|---|---|---|
| Small: 2 x 3 ft or smaller | 24″ x 36″ bathroom or basement window | 6 sq ft | $100–$400 |
| Medium: 3 x 4 ft to 4 x 6 ft | 36″ x 48″ or 36″ x 60″ bedroom double-hung | 12–15 sq ft | $200–$800 |
| Large: over 4 x 6 ft | 96″ x 60″ picture window | 40 sq ft | $700–$3,000 |
HomeAdvisor does not say whether these bands include installation, so treat them as the low side. If a quote is product-only, add labor of $100 to $400 per window (same source).
Retrofit (insert) vs full-frame replacement
This single choice explains more quote gaps than anything else. With an insert, the installer keeps the existing frame and trim and sets a new unit inside it. With full-frame, the old window comes out down to the rough opening, so new flashing, insulation and trim go in too.
| Retrofit / insert | Full-frame | |
|---|---|---|
| Installation labor per window | $100–$300 | $150–$800 (Angi: $180–$1,500) |
| Old frame and trim | Stay in place | Removed |
| Glass area | Slightly smaller (new frame sits inside old) | Same or larger |
| Can fix hidden rot or leaks | No | Yes |
| Can change style or size | No | Yes |
Quick decision checklist
- Choose an insert if the old frames are square, dry and solid, you like the current trim, and you want the lowest price.
- Choose full-frame if you see soft wood, water stains or drafts around the frame, or you want a different window style or size.
- Mix both when only a few openings are damaged.
Big-brand vs local installer pricing
Call a national full-service brand, a brand dealer and an independent installer, and the quotes can differ by thousands.
| Buying route | Typical price per window | Source |
|---|---|---|
| Independent installer, mixed brands | $450–$1,500 installed | HomeGuide, Feb 2026 |
| Andersen 100 Series, installed | $400–$1,500 | HomeGuide, May 2025 |
| Andersen 400 Series, installed | $500–$3,000 | HomeGuide, May 2025 |
| Pella vinyl, installed by Pella | $800–$1,600 | Pella, May 2026 |
| Pella fiberglass or wood, installed | $1,100–$2,200+ | Pella, May 2026 |
| Renewal by Andersen, full-service custom | $1,500–$5,000 | HomeGuide, May 2025 |
A higher price is not automatically a rip-off. You may be paying for custom sizing, a single point of contact and a longer install warranty. But compare the same window material, glass package and install method before deciding the premium is worth it.
Cost by number of windows
Here is what whole-house projects cost at different window counts. The HomeGuide column uses its $450 to $1,500 installed range; the middle column multiplies by Fixr’s $800 average.
| Windows | HomeGuide range | At $800 each | Angi project band |
|---|---|---|---|
| 5 | $2,250–$7,500 | $4,000 | not listed |
| 10 | $4,500–$15,000 | $8,000 | $6,000–$9,000 (8–12 windows) |
| 15 | $6,750–$22,500 | $12,000 | $9,000–$12,000 (12–16 windows) |
| 20 | $9,000–$30,000 | $16,000 | $12,000–$15,000 (16–20 windows) |
| 25 | $11,250–$37,500 | $20,000 | $18,000–$20,000 |
Angi’s bands shrink per window as jobs grow: 16 to 20 windows at $12,000 to $15,000 is about $600 to $940 each. Bigger orders spread setup, travel and cleanup across more openings.
Worked example (3-bedroom house, 10 windows): 8 vinyl double-hung inserts x $800 (Fixr average) = $6,400. One living-room picture window, full-frame, at $950 (midpoint of Fixr’s $300–$1,600) = $950. One small bathroom single-hung at $475 (midpoint of $250–$700) = $475. Rotted sills on 2 windows x $300 (midpoint of Angi’s $100–$500 older-home adjustments) = $600. Permit at $175 (midpoint of Fixr’s $50–$300). Total: $6,400 + $950 + $475 + $600 + $175 = $8,600, about $860 per window. That sits inside Angi’s $7,000–$9,000 estimate for a 3-bedroom home. The same 10 windows through a full-service brand at Pella’s vinyl range would be 10 x $800–$1,600 = $8,000–$16,000.
Hidden costs: trim, rot, permits, disposal
These line items turn cheap quotes into bigger bills. Ask whether each is included.
- Rot and structural repair: $100 to $2,000+ (Angi). Older-home adjustments run $100 to $500 per window.
- Siding and trim patching around full-frame openings: $2 to $14 per sq ft (HomeGuide). Our siding cost calculator helps if a whole wall needs work.
- Permits: $50 to $200 (HomeGuide) or $50 to $300 (Fixr), depending on your city.
- Disposal: often included; otherwise $55 to $65 per hour of cleanup (Angi).
- Screens: $100 to $350 per window if not included (HomeGuide).
- Lead-safe work: in homes built before 1978, the EPA requires anyone paid to disturb painted surfaces to be lead-safe certified. Tearing out old painted frames and trim usually counts, so ask for the firm’s certification.
- Contractor overhead: Homewyse’s September 2026 figure of $662 to $1,012 per vinyl window excludes permits and 13% to 22% general-contractor overhead.
Energy savings and 2026 incentives
ENERGY STAR says certified windows lower household energy bills by an average of up to 13% nationwide when they replace single-pane windows. In This Old House’s 2026 survey, 36% of buyers reported lower bills, most often by $25 to $49 a month.
Federal tax credit status (checked September 28, 2026): the Energy Efficient Home Improvement Credit (section 25C), which paid 30% of the product cost, up to $600 for windows, has ended. Under the One Big Beautiful Bill (Public Law 119-21), the IRS says the credit is not allowed for property placed in service after December 31, 2025. Windows installed in 2026 do not qualify. If your windows went in during 2025, that credit belonged on your 2025 return; ask a tax pro about amending if you missed it.
Rebates: the federal Home Electrification and Appliance Rebates (HEAR) list heat pumps, electrical panels, wiring and appliances, not windows. The whole-home Home Efficiency Rebates (HOMES) are performance-based and require at least a 20% cut in modeled energy use, so windows may help only as part of a bigger package. Each state runs its own program, so check your state energy office and your local utility before you sign.
DIY vs hiring a pro
A handy owner can set a ground-floor insert window and save the $100 to $400 labor charge per window. Full-frame work is different: flashing mistakes cause hidden leaks, and some window warranties require professional installation, so read yours first.
Safety note: second-story and large windows mean ladder work while handling heavy, awkward glass units. Call a pro for anything above the first floor, any bay or bow unit, and any opening with visible rot or water damage.
How to get an accurate quote
Get at least three quotes, ideally one from a full-service brand, one from a brand dealer and one from an independent installer. Then make sure each one answers these questions:
- Insert or full-frame, window by window?
- Exact brand, series, frame material and glass package (double or triple pane, low-E)?
- Are interior and exterior trim, capping, screens, permits and disposal included?
- What is the price per extra hour or per sq ft if rot is found?
- Separate product and labor warranties, and who honors each?
- Lead-safe certification if your home was built before 1978?
Ways to save: use inserts wherever frames are sound, stick to standard sizes and styles, replace the worst windows first, and compare quotes line by line rather than on the bottom number alone. Browse our home project calculators to budget related exterior work at the same time.
Common questions
How much does it cost to replace 10 windows?
Expect about $4,500 to $15,000 installed, based on HomeGuide’s $450 to $1,500 per window range. At Fixr’s $800 national average, 10 windows come to $8,000, and Angi estimates $7,000 to $9,000 for a typical 3-bedroom home with 10 to 12 windows.
Why do window replacement quotes vary so much?
Quotes differ mainly on install method (insert vs full-frame), who sells the window (full-service national brand vs local installer), whether the price includes installation, and the frame material and window type. Compare quotes only after matching all four.
Is a retrofit window cheaper than full-frame replacement?
Yes. Installation labor runs about $100 to $300 per window for a retrofit insert vs $150 to $800 for full-frame, according to HomeAdvisor. Full-frame is worth it when the old frame is rotted or you want a new size or style.
Is there a federal tax credit for new windows in 2026?
No. The 25C Energy Efficient Home Improvement Credit ended for property placed in service after December 31, 2025, so windows installed in 2026 do not qualify. Check your state energy office and utility for any local rebates. Status checked September 28, 2026.
How much are new windows without installation?
HomeGuide puts the window unit alone at about $250 to $1,400 or more, depending on size, material and brand. Installation typically adds $100 to $500 per window.
