TL;DR: What You Need to Know About Replacement Windows Cost

Replacement windows cost anywhere from $300 to $1,500 per window installed, with most homeowners paying around $650 to $750 each. A whole-house project of 10 to 15 windows typically lands between $6,500 and $19,000. The biggest price drivers are the window type, frame material, glass package, and labor — and here in New England, expect prices to run 15 to 30 percent above the national average. The good news? There are smart ways to bring that number down without cutting corners.

How Much Do Replacement Windows Cost on Average?

If you’ve started getting quotes, you’ve probably noticed the numbers are all over the place. That’s because “replacement windows cost” isn’t one number — it’s a range shaped by what you’re buying and who’s installing it.

Nationally, a standard replacement window runs $300 to $1,500 installed, and the average sits around $650 to $750 per window. For a full home, plan on:

• 5 windows: $3,250–$7,500
• 10 windows: $6,500–$15,000
• 15 windows: $9,750–$22,500

One thing to keep in mind if you’re shopping in Rhode Island, Connecticut, or Massachusetts: New England is one of the pricier regions in the country for window replacement. Higher labor rates and stricter energy codes push per-window costs 15 to 30 percent above the national average — often $650 to $1,050 per window installed. That makes it even more worthwhile to shop smart on the windows themselves.

Replacement Windows Cost by Window Type

The style of window you choose is one of the biggest factors in your final price. Here’s what common window types cost installed:

Single-hung and sliding windows tend to be the most affordable because they’re simple to install and widely available in standard sizes. Double-hung windows — the classic New England choice — cost a bit more but offer better ventilation and easier cleaning. Bay and bow windows sit at the top of the range because they often require structural work, framing adjustments, and significantly more labor.

Cost by Frame Material

After window type, frame material is the biggest lever on price — and it affects how long your windows last, too.

• Vinyl ($200–$1,500 installed): The most popular choice for a reason. Vinyl is affordable, low-maintenance, energy-efficient, and lasts 20 to 40 years.
• Aluminum ($175–$1,000 installed): Budget-friendly with slim, modern frames, but it conducts heat — not the best insulator for cold New England winters.
• Fiberglass ($400–$2,000 installed): A premium step up from vinyl. Stronger, longer-lasting (30 to 50 years), and better in extreme temperature swings.
• Composite ($400–$2,300 installed): Similar performance to fiberglass with a more wood-like look.
• Wood ($800–$3,800 installed): The classic choice, especially for older and historic homes. Beautiful, but the most expensive and the most maintenance-hungry.

For most homeowners, vinyl hits the sweet spot of price and performance. If you’re replacing windows in an older home, our guide to the best replacement windows for old homes walks through when wood or composite is worth the upgrade.

Factors That Influence Replacement Windows Cost

Beyond type and material, a handful of factors can move your quote up or down.

1. Glass Package and Energy Efficiency

Standard double-pane glass is the baseline. Upgrading to low-E glass with argon fill adds roughly 30 percent to the glass cost, and triple-pane runs about 80 percent more — but in a cold climate, those upgrades pay you back through lower heating bills. Many New England towns also have energy code requirements that make efficient glass the default rather than the exception.

2. Window Size and Custom Dimensions

Standard sizes are always cheaper. Custom-sized windows — common in older homes where openings have settled out of square — can add 20 to 50 percent to the price of the unit.

3. Insert vs. Full-Frame Installation

An insert (retrofit) replacement slips the new window into your existing frame and keeps labor costs down. A full-frame replacement tears everything out down to the rough opening — necessary when frames are rotted or out of square, but it can double the labor.

4. Labor

Installation typically accounts for 40 to 50 percent of your total. Labor runs $100 to $300 per window for straightforward insert installs and $150 to $800 for full-frame work. Second-story windows, hard-to-access openings, and trim repairs all add time — and time is money.

DIY vs. Professional Installation

If you’re handy, installing insert replacement windows yourself can save $100 to $300 per window — and it’s a very doable weekend project for standard-size openings in good condition. Our quick reference guide to installing replacement windows covers the basics.

That said, DIY isn’t for every situation. Full-frame replacements, bay or bow windows, second-story work, and openings with rot or water damage are best left to a pro. A poorly sealed window leaks air and water, which costs far more to fix later than professional installation costs up front.

How to Save on Replacement Windows

Here’s where a little strategy goes a long way:

• Buy surplus and overstock windows. Brand-new, first-quality windows from manufacturer overruns and closeouts sell for a fraction of retail. Same window, smaller price tag.
• Replace multiple windows at once. Installers amortize setup and travel across the job, so the per-window price drops when you do five or more together.
• Stick to standard sizes when you can. Custom sizing is one of the fastest ways to inflate a quote.
• Choose insert installation if your existing frames are sound.
• Time it for the off-season. Late fall through winter often brings better labor pricing.
• Check for energy-efficiency incentives. ENERGY STAR-rated windows may qualify for federal tax credits and local utility rebates.

Final Thoughts on Replacement Windows Cost

Replacement windows cost more than most homeowners expect — especially in New England — but the price range is wide, and where you land in it is largely up to you. Choose a practical window style, a frame material that fits your budget and climate, and a smart source for the windows themselves, and you can bring a project quote down by thousands without sacrificing quality.

FAQ: Replacement Windows Cost

How much does it cost to replace 10 windows?

Replacing 10 windows typically costs $6,500 to $15,000 installed, depending on window type, frame material, and glass package. Vinyl double-hung windows land at the lower end; wood or fiberglass frames and upgraded glass push the total higher.

Is it cheaper to replace all windows at once?

Yes. Installers spread setup, travel, and disposal costs across the whole job, so the per-window price drops when you replace several at once. Replacing five or more windows together usually delivers meaningful savings over doing them one at a time.

What is the cheapest style of replacement window?

Single-hung windows are usually the most affordable, typically $150 to $450 installed, followed by sliding windows. Both have simple mechanisms and come in widely available standard sizes, which keeps both the unit price and installation labor down.

How much should I budget for labor?

Labor typically makes up 40 to 50 percent of the total replacement windows cost. Expect $100 to $300 per window for insert installations and $150 to $800 per window for full-frame replacements, with New England labor rates running above the national average.

Do replacement windows increase home value?

Yes — window replacement consistently ranks among the better home improvement investments, with homeowners typically recouping a majority of the project cost at resale, plus energy savings every year in between.
