Updated September 2026. Cost data: 2025 Cost vs. Value Report (Zonda/JLC), manufacturer and installer price ranges published 2025–2026.
Replacing a window in 2026 typically costs $450 to $1,600 per window installed for vinyl, and $1,100 to $2,200+ for fiberglass or wood. For a typical 10-window project, national benchmark data puts a full-service vinyl job at about $22,000, so the number you actually pay depends heavily on who installs and how much of the old frame comes out.

Cost per window by material
Frame material is the single biggest price lever you control. Vinyl dominates US replacements because it is cheap to make and needs little upkeep. Fiberglass costs more but moves with temperature at a rate close to glass, which helps in climates with big swings. Wood is chosen mostly for looks and architectural detail.
| Material | Installed cost per window | Best for | Trade-off |
|---|---|---|---|
| Vinyl (regional installer) | $450–$850 | Tight budgets, standard sizes | Fewer color and profile options |
| Vinyl (brand-name, full service) | $800–$1,600 | Most homeowners | Price rises fast with glass upgrades |
| Fiberglass | $1,100–$2,200 | Extreme hot/cold climates, long ownership | Higher upfront cost |
| Wood | $1,100–$2,200+ | Historic or design-led homes | Ongoing maintenance |

Why two vinyl rows? Online averages mix two very different businesses. A regional installer quoting a standard double-hung insert is not selling the same job as a national brand with in-home consultation, custom sizing and interior trim work. Neither number is wrong; make sure you compare quotes for the same scope.
Cost by window style
Operating style changes the price because of hardware and frame complexity. The ranges below come from one regional installer’s vinyl price list, so treat them as a guide to the relative difference between styles rather than a national average.
| Style | Vinyl, installed | Notes |
|---|---|---|
| Double-hung | $450–$800 | Most common, easiest to price |
| Sliding | $500–$850 | Good for wide, short openings |
| Casement | $550–$950 | Crank hardware adds cost; seals tightly |
| Bay or bow | $1,200–$3,500 | Often priced as a project; structure and roof above add cost |

Whole-house window replacement cost
Most homes replace windows in batches. We multiplied the per-window ranges above by common window counts. These are our calculations, not quotes, and they exclude repairs to rotted framing.
| Number of windows | Vinyl ($450–$1,600 each) | Fiberglass ($1,100–$2,200 each) |
|---|---|---|
| 10 windows | $4,500–$16,000 | $11,000–$22,000 |
| 15 windows | $6,750–$24,000 | $16,500–$33,000 |
| 20 windows | $9,000–$32,000 | $22,000–$44,000 |
UpgradeWorth calculation based on the material ranges above.
For a reality check at the top of the range, the 2025 Cost vs. Value Report prices a 10-window vinyl replacement at $22,073 and the wood version at $26,781 nationally. That project assumes a full-service remodeler and a midrange specification, which is why it lands above many installer quotes.
What drives the price
Full-frame vs. insert replacement
An insert (pocket) window slides into the existing frame, which keeps labor and interior disruption low. A full-frame replacement removes everything down to the rough opening, which costs more but lets the installer fix water damage and air leaks. If your frames are soft, rotted or out of square, an insert quote is not a real saving. See full-frame vs. insert replacement windows.
Size and custom shapes
Standard rectangular sizes are the cheapest. Arched tops, large picture windows and non-standard openings require custom manufacturing and often longer lead times.
Glass package
Double-pane low-E glass is the norm. Triple-pane, laminated or impact-rated glass can add a meaningful share to each window’s price, so match the glass to your climate rather than buying the top package by default.
Access
Second-story windows, windows over roofs or landscaping, and openings in brick or stucco take longer to replace and cost more to install.
Where you live
Labor rates vary widely by metro. The same Cost vs. Value vinyl window project that averages $22,073 nationally is priced at $21,510 in Washington, DC and $20,975 in Las Vegas, and resale value swings even more between markets.
Hidden costs and quote red flags
- Frame and sill repair. Rot is usually discovered once the old window is out. Ask how the quote handles it and at what hourly or per-foot rate.
- Lead-safe work. In homes built before 1978, federal EPA rules require certified renovators and lead-safe practices when paint is disturbed. That can add cost, and a contractor who ignores it is a red flag.
- Exterior trim and capping. Aluminum capping or new trim is sometimes quoted separately.
- Permits. Many jurisdictions require them when opening sizes change or egress rules apply in bedrooms.
- “Today only” pricing. Large same-day discounts usually mean the starting price was inflated.
Federal tax credit status in 2026. The Energy Efficient Home Improvement Credit (Section 25C), which covered 30% of qualifying window costs up to $600 a year, was ended by the One Big Beautiful Bill Act for property placed in service after December 31, 2025. Windows installed in 2026 do not qualify. If a quote still advertises this credit, ask the contractor to correct it in writing. Details: window tax credit 2026.
Is window replacement worth it?
On resale alone, rarely in full. The 2025 Cost vs. Value Report estimates a vinyl window project recoups about 75.5% of its cost nationally and a wood window project about 70.1%. The case for replacing is stronger when the windows are failing, when you plan to stay long enough to benefit from comfort and lower energy bills, or when the home is going on the market with windows that would show up on an inspection report. We walk through the math in are new windows worth it.
Worth it if
- Frames are rotting, sashes won’t stay open, or seals have failed across many units
- You have single-pane windows in a hot or cold climate
- You plan to stay 10+ years
- An inspector or buyer’s agent has already flagged them
Skip it (for now) if
- Only one or two units have foggy glass: replace the glass, not the window
- The windows are double-pane and working, and energy savings are your only motive
- You’re selling within a year and the windows aren’t a visible problem
How to lower the cost
- Get three quotes on the same spec. Same material, glass package, installation type and trim. Otherwise you are comparing different projects.
- Use inserts where frames are sound. Save full-frame work for openings that actually need it.
- Prioritize. Replace the worst windows first, typically the weather-facing side, instead of the whole house at once.
- Stay with standard sizes and stock colors. Custom shapes and exterior colors add cost and lead time.
- Check state and utility programs. With the federal credit gone, local rebates are the main remaining incentive. Search your utility’s website and your state energy office.
How we got these numbers
We do not collect quotes from contractors. Per-window ranges come from published 2025–2026 price guides by a national manufacturer (Pella) and a regional installer (Thompson Creek), and we label each row with its source because they describe different service levels. Project benchmarks come from the 2025 Cost vs. Value Report by Zonda, which estimates job costs with remodeling estimating software and resale values through a survey of real estate professionals. Whole-house totals are our own multiplication of those ranges. Tax credit status is based on the law as of September 2026. Read our full methodology.
FAQ
How much does it cost to replace one window?
Usually $450 to $1,600 installed for vinyl and $1,100 to $2,200 or more for fiberglass or wood. A single window can cost more per unit than a batch, because the installer’s travel and setup are spread over fewer windows.
Is it cheaper to replace all windows at once?
Per window, often yes, because setup and travel are shared. In total dollars, replacing in phases lets you spread the cost and start with the windows in the worst condition.
Is there a federal tax credit for new windows in 2026?
No. The Section 25C credit ended for windows placed in service after December 31, 2025. Some states and utilities still offer rebates.
Does homeowners insurance pay for window replacement?
Generally only when a covered event, such as a storm or a break-in, damages the window. Age, wear and failed seals are usually treated as maintenance. Check your policy.
Do new windows increase home value?
They add value, but national data shows they typically recoup less than they cost at sale: about 75.5% for vinyl and 70.1% for wood in the 2025 Cost vs. Value Report. Results vary a lot by market.
