The cost to replace windows in a house ranges from $300 to $2,500 per window, including labor and materials. Most homeowners spend between $450 and $1,500 per window depending on the frame material, glass type, window style, and installation method. For a full-home project with 10 to 15 windows, the total cost typically falls between $4,500 and $22,500. This article breaks down every factor that affects window replacement cost, from material and labor to rebates and return on investment, so you can plan your budget with confidence.
How Much Does It Cost to Replace One Window?
The cost to replace one window is between $300 and $2,500, depending on the frame material, window style, glass type, and labor rates in your area. According to a November 2025 survey of 1,000 homeowners by This Old House, the national average cost per window is $477. Data from Angi places the average slightly higher at $750 per window, while Modernize reports a range of $614 to $1,309 per window including installation.
The wide range comes down to choices. A basic vinyl double-hung window on the first floor is on the low end. A custom fiberglass casement window on the second story with triple-pane glass and Low-E coatings is on the high end. Where you fall depends on what you pick and how complex the install is.
For homeowners in Bend and Central Oregon, costs can lean slightly higher due to the need for high-performance windows that handle harsh winters, intense summer sun, and high elevation UV exposure. Choosing the right windows for your Central Oregon home means factoring in both climate performance and budget from the start.
How Much Does It Cost to Replace All Windows in a House at Once?
The cost to replace all windows in a house at once ranges from $4,500 to $22,500 for a home with 10 to 15 windows. According to HomeGuide, the average home has about 10 to 15 standard windows, and replacing them all in a single project brings the per-window cost down by 15% to 30% compared to doing them one at a time.
There are two reasons for the savings. First, manufacturers and suppliers offer better per-unit pricing on larger orders. Second, installation crews only set up and clean up once, which cuts labor costs per window. According to Angi, replacing 25 windows in a home averages around $18,000 to $20,000 total.
Here is a rough breakdown based on the number of windows:
| Number of Windows | Estimated Total Cost | Average Per Window |
|---|---|---|
| 5 windows | $2,250 – $7,500 | $450 – $1,500 |
| 10 windows | $4,500 – $15,000 | $450 – $1,500 |
| 15 windows | $6,750 – $22,500 | $450 – $1,500 |
| 20 windows | $9,000 – $30,000 | $450 – $1,500 |
| 25 windows | $11,250 – $37,500 | $450 – $1,500 |
Sources: HomeGuide, Angi, NerdWallet (2025 data). Ranges include materials and labor for standard installations.
What Is the Average Labor Cost to Install a Window?
The average labor cost to install a window is $100 to $300 per window. According to Angi, most window contractors charge per window rather than per hour, and the fee covers removal of the old window, disposal, and installation of the new one. Modernize reports a slightly lower range of $70 to $150 per window for standard installations.
Labor costs go up when the job gets harder. Second-story windows, windows over staircases, or windows in tight spaces can add $50 to $200 per window because of the extra time, equipment, and safety precautions involved. Bay windows, bow windows, and other specialty shapes also cost more to install because of their size and structural demands.
Homeowners building new custom homes in Central Oregon should factor in labor timing early. Knowing current window lead times helps keep the project on schedule and prevents costly delays.
Does Window Frame Material Affect the Cost?
Yes, window frame material is one of the biggest factors that affects the cost of window replacement. The material you choose determines the price of the window itself, how long it lasts, how well it insulates, and how much maintenance it needs over time.
Here is how the most common frame materials compare on cost:
| Frame Material | Cost Per Window (Materials Only) | Lifespan | Maintenance |
|---|---|---|---|
| Vinyl | $100 – $900 | 20 – 30 years | Very low |
| Aluminum | $75 – $400 | 20 – 25 years | Low |
| Fiberglass | $320 – $1,500 | 40 – 50+ years | Very low |
| Wood | $150 – $1,300 | 30 – 40+ years | High (painting, sealing) |
| Composite | $300 – $1,200 | 30 – 40 years | Low |
| Aluminum-Clad Wood | $400 – $2,000+ | 40+ years | Low to moderate |
Sources: NerdWallet, Bob Vila, Modernize (2025 data). Costs are for the window unit only, not including installation.
In Bend, Oregon and across Central Oregon, window frame materials directly affect energy efficiency, which matters in a climate with freezing winters and hot, dry summers. Fiberglass and aluminum-clad wood tend to perform best in extreme temperature swings.
How Much Do Vinyl Windows Cost Compared to Fiberglass or Wood?
Vinyl windows cost $100 to $900 per window for materials only, making them the most affordable option. Fiberglass windows cost $320 to $1,500, and wood windows cost $150 to $1,300. According to NerdWallet, vinyl is the most popular frame material because of its low price and minimal upkeep.
But the cheapest window is not always the best value. Fiberglass windows last 40 to 50 years or more, while vinyl windows typically last 20 to 30 years. Fiberglass also expands and contracts far less than vinyl in extreme heat and cold, which means tighter seals and better energy efficiency over time. For a deeper look at how these two materials stack up, the comparison of vinyl vs fiberglass windows breaks down every difference.
Wood windows offer a classic look and excellent natural insulation, but they require regular painting and sealing to prevent rot and warping. For homeowners who love the look of wood but want less maintenance, aluminum-clad wood windows combine a wood interior with a weather-resistant aluminum exterior.
How Much Do Different Window Styles Cost?
Different window styles cost anywhere from $150 to $2,300 or more per window, depending on the design complexity and size. Simpler styles like single-hung and double-hung windows are the most affordable. Larger or more complex styles like bay windows and bow windows cost significantly more because of the materials and labor involved.
According to Mr. Handyman, here is what the most common styles cost for the window unit alone, before labor: single-hung windows run $150 to $400, double-hung windows run $300 to $800, sliding windows run $200 to $800, casement windows run $300 to $1,000, and picture windows run $300 to $1,200. Bay and bow windows can range from $500 to $2,300 or more according to HomeGuide.
Casement windows are a popular choice in Central Oregon because they crank open outward and create a tight seal when closed, which makes them one of the most energy-efficient window styles available. For homeowners deciding between window types, it helps to understand what casement windows are and when to use them.
How Much Do Energy-Efficient Windows Cost?
Energy-efficient windows cost $400 to $3,200 per window installed, depending on the frame material, number of panes, and coatings. According to Angi, energy-efficient upgrades like Low-E glass, argon gas fills, and triple-pane glass add $50 to $1,650 per window to the base price. The upfront cost is higher, but the long-term savings are real.
According to the U.S. Department of Energy, heat gained or lost through windows accounts for 25% to 30% of a home’s total heating and cooling energy use. Replacing old single-pane windows with ENERGY STAR certified models reduces household energy bills by an average of 12% to 13% nationwide, according to ENERGY STAR. The Department of Energy also reports that ENERGY STAR windows save 7% to 15% in annual energy costs.
For Bend homeowners dealing with below-zero winter nights and 90-degree summer days, energy performance is not optional. Learning about how to choose the most energy-efficient windows can help you pick the right glass and frame combination for Central Oregon’s climate.
Do New Windows Save Money on Energy Bills?
Yes, new windows save money on energy bills. According to ENERGY STAR, replacing old windows with certified models saves an average of 12% on energy bills nationwide. The U.S. Department of Energy puts annual savings at 7% to 15%, depending on your climate and the condition of your current windows.
The savings add up fast in a climate like Central Oregon’s, where heating and cooling demand is high for much of the year. Homes at elevation in Bend, Redmond, and Sisters face cold winters that push furnaces hard, and the high desert sun in summer drives up cooling costs. Old, drafty windows make both problems worse.
One of the biggest factors in window energy performance is the glass itself. Features like Low-E coatings, argon gas fills, and the choice between double-pane and triple-pane glass all play a role. The comparison of double-pane vs triple-pane windows helps you figure out which option delivers the best return for your home.
Is It Cheaper to Replace Windows in Winter?
Yes, it is often cheaper to replace windows in winter. Fall and winter are the off-season for window replacement. Demand drops because most homeowners schedule projects in spring and summer. Lower demand means shorter wait times, more flexible scheduling, and sometimes lower labor rates.
According to Angi, spring and summer are peak season for window replacement, which means longer waitlists and potentially higher prices. Replacing windows in the off-season can save you money and get the job done faster. Modern installation techniques allow professionals to swap windows quickly, even in cold weather, with minimal heat loss during the process.
Is It Worth Replacing 20-Year-Old Windows?
Yes, replacing 20-year-old windows is almost always worth it. Windows that are 20 years old or more are likely losing energy, developing seal failures, and showing visible signs of wear. If you notice drafts, condensation between the panes, difficulty opening or closing, or visible rot or warping, those are clear signs the windows have reached the end of their useful life.
According to the U.S. Department of Energy, heat lost through inefficient windows accounts for up to 30% of your heating and cooling bill. Upgrading from old double-pane windows to new ENERGY STAR certified models can save you hundreds of dollars per year in energy costs, while also making your home quieter and more comfortable.
If your windows are getting close to that age, it is worth learning about the specific warning signs. Knowing when your windows need to be replaced can save you from spending money on repairs that will not fix the underlying problem.
Do New Windows Increase Home Value?
Yes, new windows increase home value. According to Remodeling Magazine’s 2024 Cost vs. Value Report, vinyl window replacement recoups about 67.1% of the project cost at resale, and wood window replacement recoups about 62.9%. Data from Angi puts the overall return on investment for new windows at 70% to 85%.
The National Association of Realtors reports that homeowners can expect to recover roughly 73% of the cost of new windows upon resale. That makes window replacement one of the higher-ROI home improvement projects you can do, outperforming midrange kitchen and bath remodels in many cases.
Beyond the numbers, new windows improve curb appeal, comfort, security, and energy efficiency. According to a National Association of Home Builders survey, 90% of home buyers rate energy-efficient windows as a desirable feature. In Bend’s competitive real estate market, those upgrades can make a listing stand out.
Is It Worth Replacing Windows Before Selling a House?
Replacing windows before selling a house is worth it if the current windows are visibly damaged, drafty, single-pane, or more than 20 years old. Buyers see old windows as a red flag and will either negotiate a lower price or ask for a credit to cover the cost of replacement after closing.
If your windows are still functional and in decent shape, a full replacement may not be necessary. In that case, replacing only the most damaged or visible windows, especially the ones facing the street, can improve curb appeal without the cost of a full project. A new front door can also make a strong impression. Many homeowners in Bend pair window upgrades with a new entry door to maximize curb appeal before listing.
Are There Tax Credits for Replacing Windows in 2026?
The federal tax credit for energy-efficient windows expired on December 31, 2025. Under the Energy Efficient Home Improvement Credit (Section 25C), homeowners could claim 30% of the cost of qualifying windows, up to $600 per year. This credit was part of the Inflation Reduction Act and was terminated early by the One Big Beautiful Bill Act passed in 2025, according to the IRS.
If you installed qualifying ENERGY STAR Most Efficient windows before the end of 2025, you can still claim the credit on your 2025 tax return filed in 2026. You will need the manufacturer’s Qualified Manufacturer Identification Number (QMID) and IRS Form 5695. However, windows installed in 2026 do not qualify for this federal credit under current law.
This makes it more important than ever to explore state and local incentives. Oregon homeowners still have access to programs through the Energy Trust of Oregon and upcoming state rebates. For a broader look at what has been available, the topic of window tax credits for energy-efficient upgrades covers the details.
What Rebates Are Available for Windows in Oregon?
Oregon homeowners can get cash back through the Energy Trust of Oregon when replacing qualifying windows. The Energy Trust currently offers $1.00 per square foot for windows with a U-value of 0.23 to 0.27, and $1.50 per square foot for windows with a U-value of 0.22 or better. You must replace existing single-pane or metal-frame double-pane windows to qualify, and your home must be served by a participating utility like Pacific Power or Cascade Natural Gas.
According to the Oregon Department of Energy, new Home Energy Rebate Programs (HOMES and HEAR) are expected to launch in spring 2026. These programs will offer performance-based rebates for energy-efficiency upgrades, including windows, with additional funding reserved for lower-income households. These rebates are separate from the expired federal tax credit and are funded through state and federal allocations.
For homeowners in Bend and Central Oregon, stacking Energy Trust incentives with the upcoming state rebates could offset a meaningful portion of a window replacement project. Ask your window supplier about which products qualify before you buy.
What Is the Difference Between Retrofit and Full-Frame Window Installation?
The difference between retrofit and full-frame window installation is how much of the old window assembly gets removed. Retrofit installation, also called insert installation, fits a new window into the existing frame. Full-frame installation removes the entire window unit, frame and all, down to the rough opening.
Retrofit installation costs $700 to $1,100 per window according to Cobex Construction Group. It is faster, less invasive, and works well when the existing frame is in good condition. Full-frame installation costs $1,300 to $1,800 per window and is necessary when there is rot, structural damage, or when switching to a different window size or style.
In older homes across Bend and Redmond, full-frame installation is common because the original frames may have moisture damage or may not meet current energy codes. For new construction projects, the best window options for new construction are installed during the framing stage, which is a different process entirely.
What Hidden Costs Should I Watch for in Window Replacement?
Hidden costs in window replacement include permit fees, wood rot repair, disposal of old windows, trim work, and structural modifications. These line items are not always included in the initial quote and can add hundreds or even thousands to the final bill.
Here are the most common hidden costs to ask about: permits typically cost $100 to $400 depending on your city. Wood rot or framing damage repair can add $300 to $800 per window opening. Disposal of old windows runs $50 to $100 per window. Interior and exterior trim work adds cost if the new window is a different size than the old one. And second-story installations can add $50 to $200 per window for scaffolding or lift equipment.
Always ask for a line-item quote that breaks out materials, labor, disposal, permits, and any expected repair work. Getting everything in writing upfront prevents surprises on the final invoice.
How Long Does It Take to Replace Windows in a House?
It takes about 30 to 60 minutes to replace a single standard window. For a full-home project, a professional crew can typically install 10 to 15 windows in one day. The total timeline from consultation to completion usually runs 2 to 4 weeks, with most of that time spent on ordering and manufacturing the windows. The actual on-site installation for most homes is done in 1 to 3 days.
Complex window styles like bay windows or hard-to-reach upper-floor installations can extend the timeline. Homes with structural issues or rot found during the installation may also take longer. Planning ahead and choosing your windows early helps keep the project on track, especially during busy building seasons in Central Oregon.
Should I Replace All Windows at Once or One at a Time?
You should replace all windows at once if your budget allows it. Replacing all windows in a single project saves 15% to 30% per window compared to doing them individually, according to multiple industry sources. You also get bulk pricing on materials, lower labor costs per unit, and a consistent look across the entire home.
If a full replacement is not in the budget right now, prioritize the windows that are causing the most problems. Start with windows that have broken seals, visible damage, or the worst drafts. Replacing 5 to 10 windows at a time still offers some bulk savings while spreading the cost over multiple projects.
What Is the Best Window Material for Cold Climates?
The best window material for cold climates is fiberglass. Fiberglass expands and contracts very little in extreme temperatures, which keeps the seal tight and prevents air leaks. It is also one of the most energy-efficient frame materials available, with excellent insulation properties.
Aluminum-clad wood is another strong choice for cold climates. The wood interior provides natural insulation, and the aluminum exterior protects against moisture, snow, and ice. Vinyl works well for moderate cold but can become brittle in extreme freezing temperatures, which is a concern for homes at elevation in Bend, Sisters, and Sunriver.
In Central Oregon’s high desert climate, temperature swings of 50 degrees or more in a single day are common. Windows need to handle freezing mornings and hot afternoons without losing their seal. Knowing how cold climate windows differ from standard options helps you pick the right product for this kind of environment.
How Do I Know When My Windows Need to Be Replaced?
You know your windows need to be replaced when you notice drafts near the frame, condensation or fog between the glass panes, difficulty opening or closing the sash, visible rot or warping in the frame, or a noticeable increase in energy bills. Any of these signs means the window seals, hardware, or frame have deteriorated past the point of simple repair.
Windows older than 15 to 20 years should be inspected even if they look okay from the outside. According to HomeGuide, seals begin to leak after 15 to 30 years depending on the material and climate conditions. In Central Oregon, the combination of UV exposure, snow, ice, and dry heat puts extra stress on window components and can shorten their lifespan.
Condensation between the panes is one of the most common early warning signs. It means the seal has broken and the insulating gas has escaped, which reduces your window’s ability to block heat transfer. Learning about window condensation and how to fix it can help you decide whether a repair or full replacement makes more sense.
Frequently Asked Questions
How Many Windows Does the Average House in Bend, Oregon Have?
The average house in Bend, Oregon has between 10 and 18 windows. The exact number depends on the size and layout of the home. According to Angi, the national average is about 10 windows per home. Larger custom homes in Central Oregon, especially those designed to take advantage of mountain and Cascade Range views, often have more.
Can I Replace Just the Glass Instead of the Whole Window?
Yes, you can replace just the glass instead of the whole window if the frame is still in good shape. Glass-only replacement, also called reglazing, is less expensive than a full window swap. According to Modernize, glass replacement costs range from $280 to $325 per pane. This option works best for newer frames with a broken seal or cracked glass, but it will not fix problems with a warped, rotted, or outdated frame.
Do Double-Pane Windows Make a Big Difference Over Single-Pane?
Yes, double-pane windows make a significant difference over single-pane. Double-pane windows have two layers of glass with an insulating gas fill between them, which dramatically reduces heat transfer. According to the U.S. Department of Energy, upgrading from single-pane to ENERGY STAR certified double-pane windows can cut heating and cooling energy loss by 25% to 30%. For homes in Bend that still have original single-pane windows, the upgrade delivers the biggest energy savings of any window improvement.
How Much Does It Cost to Replace Windows in a Two-Story House?
Replacing windows in a two-story house costs more than a single-story home because of the added labor for upper-floor access. According to multiple sources including Angi and Cobex, second-story window installation adds $50 to $200 per window for scaffolding, safety equipment, and additional time. If the ground-floor windows cost $750 each, budget $800 to $950 per window for the second story.
What Window Brands Are Available in Central Oregon?
Window brands available in Central Oregon include Marvin, Milgard, Ply Gem, Simonton, Cascade, Coeur d’Alene, and Luvindow. According to the This Old House 2025 survey, brand pricing varies widely, with Milgard averaging $232 per window and Andersen averaging $740 per window. For homeowners interested in how premium brands compare, the differences between Marvin and Milgard windows come down to material options, warranty coverage, and price range.
Is It Better to Buy Windows from a Supplier or a Big-Box Store?
It is better to buy windows from a dedicated building supply partner for most projects, especially custom homes and remodels. Big-box stores carry limited stock sizes and fewer high-performance options. A local supplier offers access to a wider range of brands, custom sizing, expert product recommendations for your climate, and white-glove delivery to the job site. In a market like Bend where energy codes are strict and climate demands are high, working with a specialist makes a real difference.
Final Thoughts
Window replacement is one of the smartest investments you can make in your home. It improves energy efficiency, boosts comfort, increases resale value, and upgrades the look of your property inside and out. For homeowners in Bend and across Central Oregon, the right windows also protect against extreme temperatures, high UV exposure, and heavy snow loads that are part of life at elevation.
The cost depends on how many windows you need, what materials you choose, and how complex the installation is. But with Energy Trust of Oregon rebates, upcoming state incentive programs, and the long-term savings on energy bills, the payback on new windows starts from day one. If you are ready to get started, Lifetime Building Supply provides expert guidance, access to top window brands like Marvin and Milgard, and reliable white-glove delivery throughout Central Oregon.
