  • The majority of homeowners in our survey paid between $232 and $740 per window for their replacement projects.

Average Window Replacement Cost

The average cost to replace a single window is $477, with the typical price range falling between $232 and $740. One of the primary cost factors in a window replacement project is the number of windows you need. For example, a home with 25 or more windows can cost $11,925 or more for a full replacement project.

New windows can transform the exterior of your home while providing savings on your energy bill.

The type of windows, window frame material, and installation required for your replacement project will also affect costs. The table below shows average window replacement costs with installation and labor based on our homeowner survey responses.

Cost RangePrice Range Per WindowAverage Cost Per Window
Budget$232–$500$310
Mid-range$501–$1,000$751
Premium$1,001–$1,300$1,151
Custom$1,300–$1,500$1,400

Cost by Window Type

The type of window is another major factor in determining costs. Generally, larger or more complex window types, like double-hung or casement windows with additional sashes or hinges, cost more than basic single-hung or fixed windows. After looking at our November 2025 survey results, we found that sliding windows were the most popular choice among homeowners.

We give a quick overview of several common types of windows and how much they cost below.

  • Awning ($514): Awning windows hinge at the top and open outward, which is good for ventilation in bathrooms.
  • Bay and bow ($791–$886): Bow and bay windows extend outward from walls, creating additional interior space and panoramic views. These windows typically consist of three to four panels placed next to each other.
  • Casement ($560): Casement windows hinge on one side and open outward with a crank, offering excellent ventilation.
  • Custom ($517): Custom windows get custom-made to fit the exact style of your home and the dimensions of your window opening.
  • Double-hung ($495): Double-hung windows function like single-hung models, except both the bottom and top sashes move, providing better ventilation and easier cleaning.
  • Garden ($493): Garden windows protrude from a wall or shelf, allowing them to hold plants and other home decorations.
  • Picture ($419): These fixed windows don’t open or close, providing unobstructed views and maximum energy efficiency.
  • Single-hung ($397): Single-hung windows have a simple design in which only the bottom sash moves, making them one of the most affordable options.
  • Skylight (pricing varies): As the name suggests, a skylight is installed in the ceiling or roof of your home to admit more natural light from above.
  • Sliding ($507 per window): Sliding windows move horizontally along tracks within the window frame, which is ideal for spaces with limited exterior clearance.

Cost by Frame Material

Another major factor affecting replacement window costs is the type of frame material. The material of the window frame helps determine your window’s appearance, energy efficiency, and maintenance requirements. The most common window frame materials are aluminum, composite, fiberglass, vinyl, and wood. Each type of material has specific advantages and disadvantages that impact costs.

Did You Know

  • Fiberglass was the most popular window frame choice among our 2025 survey respondents, followed by vinyl.

The table below shows average window costs based on frame material and the pros and cons of each option.

MaterialAverage Cost Per WindowProsCons
Aluminum$448Strong, affordable, durable, offers a modern lookPoor insulation, heat and cold transfer issues
Fiberglass$491Very durable, energy-efficient, low-maintenanceLimited color options
Vinyl$527Affordable, energy-efficient, low-maintenanceLimited colors, less rigid than other materials
Composite$529Combines wood’s look with vinyl’s durabilityHigher cost than vinyl, fewer manufacturers
Wood$567Beautiful appearance, excellent insulatorRequires maintenance, susceptible to rot and pests

Cost by Installation Method

The way you install replacement windows has a major impact on both the total cost and your project scope. You can choose between two approaches when replacing your home’s windows: a retrofit installation or a full-frame installation. The method you choose will impact labor time, materials, and the extent of changes needed to your home’s existing structure.

  • Retrofit installations: A new window is installed inside an existing frame for a faster and more affordable option. Because the process leaves surrounding finishes untouched, it causes minimal disruption to your home. This method works best when existing frames remain square and level, and it slightly reduces the window’s glass area.
  • Full-frame installations: Removes the entire window down to the rough opening, which takes longer because of added finishing work and costs more. However, contractors can inspect and repair hidden damage, improve insulation, and maintain the original glass area. 

Your window installer can help determine whether your project requires a retrofit or a full-frame installation based on the condition of your windows and the surrounding area. A retrofit installation typically works best for homes under 20 years old with intact frames. A full-frame installation is best suited for older homes, houses with damaged frames, or homeowners who want style or size changes.

Homeowner Insights

  • Nearly half of homeowners in our November 2025 survey said it took contractors between two and three days to finish their window installation. Another 33% said it took one day or less.

Additional Window Replacement Cost Factors

In addition to the window type, material, and installation method, several other factors can affect the total cost of window replacement. We break down other cost factors of a window replacement project below so you better know what to expect.

Glass and Pane Type

The type of glass and the number of panes you choose directly affect the cost of your replacement windows. Most replacement brands only offer double- or triple-pane windows because single-pane versions aren’t energy-efficient. If cost is a concern, you can buy new construction windows, which manufacturers typically make with affordable materials.

Did You Know

  • Nearly 80% of our survey respondents chose to install double-pane windows, rather than single- or triple-pane models.

Here’s an overview of the most common glass panes for new windows:

Single-pane windows are generally the most affordable because of their single-glass construction. However, they’re the least energy efficient because hot and cold air can easily enter and escape through a single glass pane.

Double-pane windows have two panes of glass and an insulating gas, like argon or krypton. These materials serve as an insulating barrier, keeping home temperatures and noise levels comfortable.

Triple-pane windows offer even greater insulation than double-pane windows because of their additional third pane of glass. They’re suitable for extremely hot or cold climates but have the highest cost of all window pane types.

Here’s a breakdown of the most common glass treatment options:

Low-emissivity (low-e) coatings are microscopic, transparent layers applied to window glass that reflect thermal energy away from the window. This coating is especially useful for windows that receive a lot of sunlight throughout the day. We found that low-e coatings were the most popular glass enhancements among respondents in our November survey.

This glass offers semi-opaque views, allowing sunlight to travel through your window while blurring the view into your home.

This glass option contains resin for added durability, making it up to five times stronger than normal glass.

This glass offers better protection than laminated glass, blocking debris damage caused by inclement and extreme weather. Tempered glass is common in windows near doors and in those that extend to the walking surface.

Window Size

Window size directly affects both replacement window manufacturing and installation costs. Generally speaking, standard window sizes fit common rough openings, which keeps prices low and simplifies the installation process. Manufacturers typically produce standard sizes in large quantities, making them readily available and more affordable for most window styles.

Custom and oversized windows increase overall project costs because they require specialized production and installation methods. For example, installers must use special handling equipment and materials for large windows, which extends labor time and increases risk during installation.

Standard window sizes typically don’t require specialized installation methods or equipment, which will keep labor costs down.

Window Features and Hardware

The features and hardware you buy can also raise your total window replacement costs. Upgraded window features enhance both performance and appearance, but also increase total project cost. Homeowners often add design elements like window grids or grilles, or between-glass blinds for a clean, low-maintenance look. These upgrades enhance comfort and style, creating a more personalized finish.

Hardware and security options also impact overall pricing. Premium hardware finishes, like brushed nickel or bronze, will increase costs compared to standard hardware. Features and accessories, like window cranks, shutters, or specialty operating mechanisms, can add extra curb appeal but also increase the overall cost of your new windows.

Installation Details

The time of year you replace your windows can impact cost. Spring and summer are the busiest seasons for window replacement, so pricing is often higher, particularly when it comes to contractor costs. The best time of year to replace windows is fall or winter if your timeline and climate allow it. You may get a deal during these seasons on materials and from installers looking for work.

Also note that windows on the second floor or above, or in challenging spots, can make installation more difficult and expensive.

Hidden Costs

As with any home improvement project, knowing about hidden expenses can help you avoid sticker shock when your contractor reveals the total cost of your window replacement project.

  • Permits and inspections: Local building codes often require permits for window replacement projects, particularly with full-frame installations. Permit fees depend on your location and project details. Before starting a window replacement project, check your city or county regulations to ensure compliance.
  • Historic homes: Homes located in historic districts can face additional requirements that can significantly raise costs. Preservation boards often review window materials, styles, and installation methods to maintain a property’s architectural integrity.
  • Structural repairs: Window replacement sometimes uncovers hidden structural issues that need fixing before you can install new windows. Removing old windows can reveal water damage, rot, or weakened framing. Repairing a rotted frame, for example, typically costs $250–$800 depending on the extent of the damage and type of material.
  • Disposal fees: Reputable contractors include old window removal in most installation quotes, but it’s important to confirm this to avoid unexpected charges at the end of the project. In general, expect to pay between $55 and $65 per hour for standard window removal and disposal, depending on the size and weight of the materials.

We recommend planning a 10%–20% buffer in your window replacement budget to help offset any surprise costs.


Energy Efficiency and Return on Investment

When shopping for replacement windows, it’s important to consider the overall energy efficiency of the windows you’re looking to buy. Energy-efficient windows offer long-term savings by lowering utility bills and boosting your home’s value. Upgrading to modern, high-performance windows improves comfort, reduces drafts, and minimizes strain on HVAC systems—all while providing a measurable financial return over time.

Energy Savings

Energy-inefficient windows are a major cause of heating and cooling costs, according to the U.S. Department of Energy (DOE). The DOE estimates that 25%–30% of residential heating and cooling energy use is due to losses from poorly insulated windows.

To confirm the DOE’s claims, we asked our November 2025 survey respondents about how much they saved on their electricity bill after installing new windows. Over 66% of homeowners reported saving between $25 and $100 per month on utility bills since replacing their windows. These savings can grow over time, especially in regions with extreme temperatures. Nearly 95% of respondents said their new windows made their home somewhat or much more comfortable than before.

When shopping for windows, we suggest choosing Energy Star-certified models. Windows with this certification offer up to 13% more energy savings than single-pane, non-certified models. They achieve this by reducing heat transfer, blocking unwanted solar gain, and maintaining stable indoor temperatures year-round. Choosing the right glass coatings and frame materials maximizes energy performance for every home.

Window Replacement Return on Investment

Alongside the energy savings you can achieve with new windows, you’ll also get a solid return on investment (ROI) in the form of increased home value. Vinyl replacement windows will recover up to 76% of the original price you paid should you plan to sell your home, according to the Journal of Light Construction’s 2025 Cost vs Value Report. The report also notes that wood windows can recover up to 70% of their original cost. The combination of increased energy savings and boosted curb appeal makes window replacement one of the strongest long-term home improvement investments.

Energy Efficiency Ratings Explained

Understanding energy performance ratings can help homeowners select windows that strike a balance between insulation, light, and comfort. Each rating highlights a different efficiency aspect, making it easier to compare products and choose the best option for your home and climate.

  • U-Factor: The U-factor rating measures the amount of heat that a window allows to pass through the glass. Lower values mean better insulation and improved indoor comfort. Look for a rating of 0.30 or lower for optimal efficiency.
  • Solar Heat Gain Coefficient (SHGC): The SHGC rating indicates how much solar heat enters through a window’s glass. Lower values block more heat, ideal for warm climates, while moderate values work better in colder regions.
  • Air Leakage (AL): The AL rating indicates the amount of air that can pass through window joints. Lower numbers indicate tighter seals and reduced drafts. Aim for a rating of 0.3 or lower.
  • Visible Transmittance (VT): The VT rating measures the amount of natural light a window allows into a room. Higher numbers provide brighter interiors without increasing energy use.

Finding the Most Cost-Effective Replacement Windows

The most cost-effective window replacement doesn’t always come in the form of the cheapest windows available. Our research shows that the most cost-effective window replacement involves selecting a window with the most energy-efficient features tailored to your specific climate.

“Windows that are poorly made or installed can cause discomfort, increase energy costs, and cause damage to your home down the road, so plan carefully,” said Amanda Hatherly, the CEO of Building Performance Institute.

What To Ask a Professional Window Installer

Our team spoke with Mark Waddell, the installation and application manager at Cornerstone Building Brands, to get advice on what homeowners should ask their window installer before hiring them. Here’s what he had to say:

Questions to Ask Your Window Installer

  1. How long have you been in business?: Although everyone must start somewhere, companies that have been in business for more than five years are generally more established. If a business is less than five years old, ask for references and do research online to evaluate its ratings.
  2. Do you have a contracting license?: Licensing requirements vary by state and aren’t always required. In some states, licenses are required to pull a permit for work.
  3. Do you have workman’s compensation and general liability insurance?: In some states, based on the size of the company, workman’s compensation insurance may not be required. However, this insurance protects the homeowner from financial responsibility for any injury a worker may sustain while working on their home. General liability insurance protects homeowners financially from accidental damage caused by the installer during the installation process.
  4. Will they be pulling a permit for the work?: Most professional companies will pull the permit themselves. Occasionally, a contractor may ask a homeowner to pull the permit to save money on the job. This is often an indication of an unlicensed contractor, so beware.

Best Companies for Budget-Friendly Window Replacement

In addition to reviewing more than a dozen window brands and their offerings, we gathered cost information from our November 2025 window survey. Our 1,000 survey takers reported cost averages for 16 popular brands, including Renewal by Andersen and Window World.

We found that most brands charge between $232 and $740 per window. Our survey showed Milgard and Jeld-Wen as the least expensive, at $232 and $322 per window, respectively. Simonton and Andersen windows were the priciest, at $690 and $740 per window, respectively. While price is important, we recommend also considering factors like a company’s reputation, warranty coverage, and window installation process.

Check out our recommendations for top-rated window brands based on price, aesthetics, and energy efficiency:


Choosing Between Professional and DIY Installation

While you can install replacement windows yourself, it may not save you as much money as you think—and it can void your warranty coverage. Say you choose a do-it-yourself (DIY) installation and encounter an issue with your window later on. Your window manufacturer may not accept the warranty claim because coverage typically requires professional installation.

“One of the biggest additions to the cost would be a contractor having to come in and repair work that is done incorrectly,” said Jason Hensler, the president of the National Association of the Remodeling Industry. “Hidden costs can sneak up on you if you are unprepared.”

It’s also typically safer to leave installation to the professionals if you’re inexperienced with this type of project, to ensure safety and quality work. For these reasons, we typically recommend using a professional for replacement window installations.


How To Save on Window Replacement

While installing new windows is often an expensive project, you can lower your costs with local and federal tax credits, rebates, and other incentives. We discuss several ways to save on window replacement below.

  • Choose affordable window options: Buying budget-friendly window replacement options and styles, like vinyl and double-hung windows, can help keep costs low. Although vinyl windows may not have the same visual appeal as wood or fiberglass, they’re energy-efficient and affordable.
  • Negotiate the price: Not every contractor is willing to negotiate an estimate after giving you a quote. However, it’s worth trying to make a counteroffer if the quoted price is more than you expected.
  • Rebates and incentives: Check with your local utility company for any available rebates and incentives. Some states offer tax credits and rebates for energy-efficient home improvements, including windows. You can check the Database of State Incentives for Renewables and Efficiency (DSIRE) for available incentives in your state.
  • Tax credits: You can claim up to 30% of installation costs, up to a maximum credit of $600, when replacing your windows, according to Energy Star. This credit applies to your primary residence and is available from Jan. 1, 2023, to Dec. 31, 2025.

Survey Insights from Homeowners Nationwide

In November 2025, our team surveyed 1,000 homeowners who replaced their home’s windows within the last five years. The survey helped us gain a deeper understanding of the overall customer experience of shopping, selecting, and installing replacement windows. Here’s what we found:

  • Average home age: Over 28% of our November 2025 respondents reported that their home was between five and 10 years old when they decided to get new windows. The next most common home age was under five years old (25%).
  • Most popular window brands: We found that Andersen Windows (21%) was the most popular window brand. The second most popular brand was big-box retailers (15%), including Home Depot and Lowe’s.
  • Reasons for window replacements: The primary reason our respondents replaced their windows was due to physical damage (37%).
  • Overall satisfaction: We found that 95% of our respondents were either satisfied or very satisfied with their new replacement windows overall.

FAQs About Window Replacement Costs

What is the cheapest type of window you can buy?

The cheapest window you can buy is an aluminum, single-hung window with single-pane glass. While you’ll pay less for this option upfront, it doesn’t yield a significant return on investment due to its low energy efficiency. A more energy-efficient option that’s still budget-friendly is a vinyl, double-hung window with double-pane glass.

Does replacing my old windows increase my home’s value?

Yes, replacing your old windows can increase your home’s value. Replacing vinyl windows can add an average of $16,657 to your home’s resale value, and wood windows added an average of $18,764, according to the Journal of Light Construction’s 2025 Cost vs. Value report.

Can I save money by installing windows myself?

Doing installation yourself eliminates labor fees, which can save you a few hundred to a few thousand dollars, depending on the number of windows you’re installing. However, improper installation can leave you with even costlier issues down the line. Not only can unlicensed window installation void your manufacturer’s warranty if you ever need to file a claim, but improper installation and sealing of windows can also cause air and moisture leakage issues, which can drive up your energy bills or lead to mold growth in your home.

How can I tell if my windows need a repair or replacement?

A window repair makes sense when windows show mild wear but still operate effectively. Minor issues like worn caulking, broken locks, or small cracks in glass often cost little to fix. Replace your home’s windows if there’s damage to the glass or framing, your home is drafty, your energy bills are rising, you spot condensation between the window panes, your windows are letting in moisture, or your windows allow in more noise pollution than you want.

Is it cheaper to replace all windows at once?

While the total project cost of replacing every window in your home may be higher than replacing one, most window companies offer better discounts when you buy multiple windows. Many companies also provide better labor rates when installing numerous windows, which you may miss out on if you purchase fewer units. For homes with 5–25 windows, the cost can range from $2,385–$11,925.


Our Rating Methodology

Our team backs up our window ratings and recommendations with a detailed rating methodology to objectively score each provider we review. Our research included speaking with company representatives, browsing product selections, reviewing window details, and conducting consumer surveys. We then scored each provider against our review standards based on window variety and features, cost, value, trustworthiness, and customer service to determine a final score on a 5-point rating scale.

How We Determined Window Replacement Pricing

To provide the most accurate and current pricing for window replacement, we collected cost estimates from our November 2025 survey of 1,000 homeowners who replaced their windows within the last five years nationwide. Our research involved analyzing costs based on window material, style, glass, and additional features. We also looked at installation costs in different regions across the country. This approach allowed us to determine project estimates for different homeowner situations.
