How Much Does a Window Replacement Cost in 2025?

Average Window Replacement Cost

Window Replacement Cost Factors

The size and number of your windows, as well as full-frame vs. retrofit replacements, will have a significant impact on your total window installation costs.

Size

Even the smallest window will typically cost at least $100. Various brands also price their products differently. A higher-end brand might charge $1,200 for a standard window, while a budget-friendly brand might only charge $300. There are hundreds of stock sizes available directly from manufacturers and most big box home improvement stores. 

Number of Windows

If you’re planning to replace multiple windows in your home, it’s usually best to get them all done at once. This can save you on transportation fees and minimum fees charged by some window professionals. In some cases, such as switching from single-glazed to multi-glazed windows, you may want to replace all the windows in your home.

Full-Frame Window vs. Retrofit Replacement 

A retrofit window installation means a contractor will insert a new window sash into the existing window frame. A window sash is the window section that holds the glass in place. On the other hand, a full-frame window replacement means a contractor will replace everything, including the glass panes and frame. 

A retrofit window replacement is less labor-intensive, less expensive, and preserves the existing trim. However, a retrofit window replacement is only a good choice if your current frame is structurally sound. 

A full-frame window replacement allows the installer to inspect and repair water damage. This also offers the homeowner an opportunity to replace a window with a new style. However, expect to pay more for a full-frame window replacement. 

Labor

Most window installers charge about $40 to $65 per hour. Expect to pay more in metropolitan areas like San Francisco or New York City or if you have a complicated project. For example, replacing one window in a single-story suburban home built in the last 20 years might be a quick two-hour job, but a third-floor replacement in an old row home may take six hours or longer. 

Complex installs—as dictated by the age of the home, accessibility, and location—can increase the cost to $600 or more per window. Some other factors that play into labor include: 

• Travel time

• Fuel and transportation costs

• Cleanup and disposal fees 

Given the fixed overhead on this type of work, you can save on labor by replacing more windows rather than one window at a time. 

Other Window Replacement Cost Factors

In addition to key factors like the size and number of windows, you’ll also want to consider how home age, structural repairs, energy efficiency, and permits may impact your total costs.

Home Age

Replacing windows on older homes can double or triple the final project price. The unique challenges include custom pieces made to fit non-standard sizes, repairing or replacing rotted or broken trim, matching historical architecture, removing counterweights, upgrading to current code standards, and filling empty areas with insulation. It’s a fairly common problem, as about 14% of the nation’s housing is made up of homes more than 70 years old.

Structural Repairs

A crack running from one side of a window to another might be a pressure crack, meaning there might be a serious problem with your home's structure. Keep in mind, though, that houses naturally settle about 10 years after they're built. 

Energy Efficiency

Windows can account for 25% to 30% of your home's heat loss, so replacing them with Energy Star-rated products can help you save on your utility bills. When shopping for energy-efficient windows, you'll have many options to choose from. You'll find that vinyl, wood, and fiberglass are much better insulators than aluminum, but any frame material can include high-efficiency glass and low-emissivity coatings. On average, thermally insulated, energy-efficient windows run about $120 to $1,200 or more.

"When considering cost versus value for energy-efficient windows, remember that the same qualities that make a window efficient also make your home's climate more comfortable,” says Cati O'Keefe, Expert Home Building & Sustainability Contributor. “Good windows prevent cold and hot spots, which may make them worth the additional expense."

Even if you buy energy-efficient windows, they have to be installed appropriately. Trained pros should install your windows according to the manufacturer's instructions. If they fail to do this, your warranty may become void. 

Permits

Some window replacements may need permits, which can cost between $50 and $300. If you’re planning to replace just the movable parts, sash, or the section that holds the glass in place, you won’t need one. But if you’re altering the structure of your home, such as putting in a larger window, you’ll need to apply for a permit. 

Cost by Window Material

You'll spend anywhere from $75 to $1,500 for the window alone. There are five main types of window materials with varying costs and energy efficiency levels. 

Aluminum Windows 

Aluminum windows cost around $75 to $400 per unit and are affordable, lightweight, and sturdy. However, some homeowners may not like the look of metal on windows. They’re less energy-efficient than vinyl but comparable in price.

Vinyl Windows 

Vinyl is the most popular window replacement style because it’s affordable, costing around $100 to $900 per window. Vinyl is very durable and typically doesn’t need a lot of repairs. It’s also worth highlighting that vinyl is less energy-efficient than fiberglass.

Wood Windows 

Wood windows cost approximately $150 to $1,300 per unit and are suitable for homeowners who have older or historic homes. However, it’s important to note that wood doesn’t resist moisture, meaning wooden windows can rot or become susceptible to mold. On the plus side, wood windows are more energy-efficient than vinyl ones.

Composite Windows 

Composite windows cost around $300 to $1,200 per unit. Some composite windows are made of reclaimed wood fiber and thermoplastic polymer and can resist rot, decay, and fungal growth. If the composite is made from wood, these windows may also be energy efficient. Composite windows are twice as strong as vinyl windows, but keep in mind that this material is more expensive than most other window materials. 

Fiberglass Windows

Fiberglass windows are the preferred material for windows these days and cost around $500 to $1,500 per window. Fiberglass windows are more expensive than most other window materials, but they’re more energy-efficient than vinyl, come in more color options, and have a long lifespan.

Cost by Window Type

The price of your windows will also be affected by the type of window you select. You'll make this decision primarily based on aesthetics and the amount of light, ventilation, and access you need. Here are the most common window types for homes:

Single-Hung Windows

Single-hung windows are the most popular style and cost $100 to $400 each. They have a vertical opening with a single lower sash that allows ventilation and remains flush with the wall, so they’re a great option for walls facing a walkway. Single-hung windows can provide a more authentic look in historic homes. 

Double-Hung Windows

Double-hung windows cost between $150 and $650 each. While they look like single-hung windows, both the upper and lower sashes move, allowing ventilation from the window's top or bottom. It isn't a good idea to replace these yourself because they're heavier, and the complexity of moving parts means more opportunities for costly mistakes. Double-hung windows also require the highest quality frame. 

On the plus side, double-hung windows are easier to clean than single-hung ones. They allow for more ventilation for rooms with lots of moisture and are more secure because of double-locked units. 

Picture-Style Windows

Picture-style windows cost anywhere from $65 to $700 or more each, depending on the size. They’re a simple square or rectangle shape with a glass pane that doesn’t open, although some have a side panel for ventilation and can make a sunroom brighter or enhance your home’s curb appeal. 

Casement Windows

Casement windows run from $150 to $1,000 each. They’re hinged on one side and crank open to allow for ventilation. These types of windows are common above kitchen sinks. 

Sliding Windows

Sliding windows run from $150 to $800 each. They open on a track from side to side and are sometimes referred to as horizontal windows, sliders, or gliders. Some people find these windows easier to open than casement windows.

Folding Windows

Folding types, also known as pass-through windows, are custom installations and range anywhere from $500 to $900 each. They don’t take up as much space as an open door but still open up to offer ventilation and light.

Storm Windows

Storm or hurricane windows cost $90 to $400 each and can either be interior or exterior windows. These can help reduce airflow in and out of existing windows and lower energy bills because low-E, or low-emissivity, storm windows reflect heat into the house during colder months and help the home stay cooler during the summer. 

Bay Windows

A bay window costs $910 to $7,100 each but can go up if you need to open up a wall for it. Bay windows feature three panes joined at an angle that extrude from a living space or bedroom. These windows are popular because they let in a large amount of light from various directions. They also increase curb appeal and can be as functional as they’re decorative, with the addition of seating or shelving.

Bow Windows

Bow windows cost anywhere from $1,500 to $6,500 each. They’re like bay styles but have a minimum of five panes rather than three, with glass panels at equal angles that form a semi-circle “bow.” 

Bow windows fit well in Victorian-style homes, but they make an elegant architectural touch in most settings. Installing a bow window where one doesn’t already exist can cost significantly more because you’ll need to factor in new framing, drywall, and any extra roofing and siding. 

Custom Windows

Custom work is always more than standard replacements and starts at $1,000 each. Custom sizes and installations are common among older homes where standard opening sizes weren't used.

When Do You Need a Window Replacement? 

You may want to replace your windows just to refresh and modernize the look of your home. But most often, homeowners look to replace them when they just aren't functioning the way they should. Here are some common reasons why homeowners might consider replacing their windows.

Higher Bills

You’ll likely need a window replacement if your energy bills are skyrocketing. Drafts make your air conditioning or heating system work harder. One way to tell if your window needs to be replaced is to take a lighter and hold it near your window. If it flickers, there's a draft coming in. 

Functionality

If you’re having problems opening and closing your windows or they show visible damage or moisture, chances are you’ll need to replace them. 

Sound

Single and some double-pane windows can't block sound vibrations from your street. New windows will help with soundproofing, and energy-efficient ones can even absorb sound waves before entering your home. 

Decaying Frames and Leaky Windows

A leaky window is hard to miss, but a wooden frame that’s seen too much moisture is more subtle. Call in a pro before there’s serious decay, which could cause safety issues. 

Window Replacement vs. Repair

Depending on the problems you’re experiencing with your windows, it may be possible to repair rather than replace your windows. Most homeowners spend an average of $400 on window repairs, compared to $850 for a full replacement. Repairs can be a good solution if you need to fix a minor leak or repair a thermal seal, which can fix issues with drafts and moisture. A small window crack can also be repaired for around $100, but a larger crack may require you to replace the window glass.

If your window has extensive damage to the glass, frame, or sill, you may want to consider replacement. This may also be a good fit if you want to improve your overall home energy efficiency by swapping out single-glazed windows for double or triple-glazed windows.

Does Window Replacement Increase Home Value?

Window replacement may increase your home’s value, depending on the type and quality of windows you choose. A standard window replacement won’t usually make a large difference, although it may be necessary if your windows are damaged. Installing some window types, like smart glass, can improve your privacy but may not suit the tastes of every buyer. However, installing high-quality, energy-efficient windows can be a draw for many potential home buyers. 

Good windows increase the comfort of your home by providing improved temperature regulation. Energy-efficient windows can also reduce your utility bills, which offers cost savings even while you live in your home. Finally, new windows can improve your home’s curb appeal, which may increase home value or help your home sell more quickly.

Budgeting for Window Replacement

Window replacement typically requires professional tools and expertise, but there are plenty of steps you can take to keep your installation on budget:

• Consider long-term costs: While single-glazed and simple windows cost less upfront, they don’t offer the same temperature regulation as higher-quality, multi-glazed models. It may be worth investing in a double-glazed or triple-glazed window if it will reduce your utility bills in the long run.

• Shop in bulk: Many window suppliers offer discounts for buying in bulk, so if you expect you’ll need to replace multiple windows, it may be more cost-effective to do them all at once.

• Browse second-hand: Professional contractors often donate construction materials to places like Habitat for Humanity. This can be a great way to get like-new windows for an affordable price while keeping materials out of the landfill.

• Look for rebates: There are many local, state, and federal grant and rebate systems for installing energy-efficient home improvements. These can reduce the costs for things like double and triple-glazed windows and, in some cases, may even make them more affordable upfront.

• Contact multiple pros: Reach out to several window replacement professionals in your area to compare quotes and find the best price.
