Window replacement typically costs $450 to $1,200 per window installed, with most homeowners paying an average of around $700 to $750 per window. A full home with 10 to 15 windows generally runs $6,500 to $18,000, depending on the frame material, glass package, and window style you choose. This guide breaks down the real cost factors so you know what to expect before you get a quote.
How much does window replacement cost on average?
A professionally installed window typically costs $450 to $1,200, averaging around $700 to $750 per window. Here is what a typical project looks like at different scales:
| Project size | Estimated cost range |
|---|---|
| Single window | $450 to $1,200 |
| 5 windows | $2,500 to $6,000 |
| 10 windows | $4,500 to $12,000 |
| 15 windows (full house) | $6,500 to $18,000 |
Replacing all your windows in one project instead of one at a time often lowers the per-window cost by 10 to 20 percent, since labor and setup are shared across the job.
How much does frame material affect the cost?
Vinyl is the most affordable and popular frame material, generally running $300 to $900 per window. Fiberglass and wood cost more but offer different durability and aesthetic trade-offs.
| Frame material | Typical cost per window | Why choose it |
|---|---|---|
| Vinyl | $300 to $900 | Best balance of cost, energy efficiency, and low maintenance |
| Fiberglass | $450 to $1,500 | Very durable, holds paint well, minimal expansion and contraction |
| Wood | $400 to $2,000+ | Classic look, but requires ongoing maintenance |
| Aluminum | $75 to $500 | Budget-friendly but less energy efficient |
For most homeowners, vinyl offers the strongest overall value: it costs less upfront, insulates well, and never needs painting or staining.
Does window style change the price?
Yes. Double-hung windows are the most common and moderately priced, while bay, bow, and casement windows cost more due to their shape and more complex installation.
| Style | Typical installed cost | What to know |
|---|---|---|
| Double-hung | $350 to $700 | The most popular style, offering a good balance of function and cost |
| Casement | $400 to $800 | Crank-out windows that seal tightly |
| Sliding | $300 to $700 | A simple, budget-friendly option for wide openings |
| Awning | $400 to $800 | Hinged at the top for ventilation in light rain |
| Bay or bow | $1,500 to $5,000+ | Multi-panel windows that project outward and need structural support |
| Picture | $400 to $1,500 | Large, fixed windows priced by size rather than a flat range |
How much does the glass package add to the cost?
Basic double-pane glass runs $300 to $900 per window. Low-E coatings and triple-pane glass cost more upfront but improve insulation, which matters for North Jersey's cold winters and humid summers.
| Glass type | Typical added cost | Benefit |
|---|---|---|
| Double-pane | $300 to $900 | Standard insulation, big step up from single-pane |
| Double-pane with Low-E coating | $400 to $1,200 | Reflects heat, blocks UV, reduces fading |
| Triple-pane | $600 to $2,000+ | Maximum insulation and sound reduction |
In North Jersey's climate zone, Low-E glass with argon or krypton gas fill is generally the sweet spot. It meaningfully cuts heating and cooling loss without the full cost jump of triple-pane, which tends to make more sense in especially cold climates or on noise-heavy lots.
Is there still a tax credit for energy-efficient windows?
No. The federal Energy Efficient Home Improvement Credit (Section 25C), which offered up to $600 back on qualifying windows, expired for any windows installed on or after January 1, 2026.
This is one of the most common questions homeowners ask, and it's worth getting right, since a lot of information online is outdated. The 25C credit let homeowners claim 30 percent of the cost of qualifying windows, capped at $600 per year. Under the tax law signed in July 2025, that credit was accelerated to expire at the end of 2025, so windows installed in 2026 or later do not qualify for a federal credit. If you're unsure whether any state or utility rebate programs apply in North Jersey, it's worth asking your installer or checking with a tax professional, since those programs can change independently of the federal credit.
The stronger financial case for replacing older windows now is what they do to your monthly energy bill and comfort, not a one-time credit. Upgrading from old single-pane or failed double-pane units to a modern Low-E package continues to save money every month for the life of the windows.
What other factors affect window replacement cost?
Beyond material and glass, installation type, window size, number of windows, and any structural repairs needed all move the final price.
- Installation type -- A retrofit or insert install (fitting a new window into the existing frame) is generally less expensive than a full-frame replacement, which is needed when the existing frame is damaged or you want to change the window's size.
- Window size -- Larger windows and custom sizes cost more in both materials and labor.
- Number of windows -- Bulk projects typically bring the per-window price down.
- Structural issues -- Rot, water damage, or an out-of-square opening adds repair costs on top of the window itself.
- Removal and disposal -- Hauling away old windows is usually included but worth confirming in any quote.
Is window replacement worth the cost?
Yes, for most homes. New windows typically recoup 50 to 75 percent of their cost in resale value and continue lowering energy bills for decades.
Beyond resale value, new windows cut drafts, reduce outside noise, and stop the fading that UV rays cause to floors and furniture. In North Jersey, where winters are cold and summers are humid, the ongoing energy savings from a properly sealed, Low-E window often matter more over time than any single upfront number.
How can you keep window replacement affordable?
Compare quotes, choose standard sizes when possible, replace all windows in one project for bulk pricing, and ask about financing.
- Compare multiple quotes to understand fair pricing for your specific home.
- Stick to standard sizes and styles where you can, since custom windows typically cost 25 to 50 percent more.
- Replace windows together rather than one at a time to capture bulk pricing.
- Ask about financing. Spreading the cost into monthly payments can make a full-house project more manageable.
