Installing new windows is a fantastic way to get a new view of the world outside—and light up your world inside. Replacing a window costs about $650 on average. However, the price depends on your window type, material, size, whether it is an energy-efficient window, and whether you replace it yourself or hire a professional. Read on to learn all the window replacement cost factors.

Factors That Impact Window Replacement Pricing

New window installations and replacements range greatly in price because there are so many factors that can impact what you pay. Everything from the size of your unit to the material used to where they’re installed in your home will determine how little or how much you spend. 


Size is an important factor when calculating the cost of window replacement. In general, the larger the window, the more expensive a replacement will be because of all the extra materials and labor involved.

While window replacement is often simple, it’s not uncommon to encounter additional costs during the course of the project. In addition to the cost of window replacement, you may find yourself needing to pay for structural repairs, waterproofing, insulation, clean-up, and disposal.


A major factor in calculating the cost of window replacement is the material you choose. Popular choices include vinyl, wood, fiberglass, aluminum, and composite. Expect to spend between $75 to $1,500 per window unit, not including labor. Custom, lavish, or extra-large projects can add 25% to 50% to the total project cost.

Material Pros and ConsCost per Window
VinylLow maintenance, economical, durable, energy efficient and long lasting$100 – $900
WoodAlign well with classical architecture and known for preserving the integrity of historical homes$150 – $1,300
FiberglassEnergy efficient, low maintenance and mid-range in cost$500 – $1,500
AluminumDifficult to insulate and paint, lower cost than many other window types$75 – $400
Composite Low maintenance, durable, look similar to wooden windows$300 – $1,200

Window Styles

When calculating the cost of replacement windows, it is essential to consider the window style. Common window styles include bay or bow, casement, custom, double-hung, energy-efficient, fixed and picture casement, single-hung, sliding or folding, storm, and pocket.

Home Age

The age of your home also impacts what you’ll pay. Replacing a window on a newer property will generally cost less than replacing one on an older property, because the latter may require refitting, demolition, and sometimes custom-made pieces to ensure the new installation is up to modern-day code. Pros may need to remove or replace additional parts, like a broken or rotting trim, and this additional labor and materials will add up on your final bill.

Home Location 

Where windows are located on a home also impacts the overall cost of replacements. For example, windows positioned on the ground floor generally cost less to replace than ones on higher levels or others that are located slightly underground (like an egress window), because they don’t involve as much labor. On the flipside, tough-to-reach windows may require additional tools and steps to install properly, like an extendable ladder or land excavation for a basement window.

Energy-Efficient Window Replacement Costs

Energy-efficient windows generally cost between $120 and $1,200 per window. Quality, efficiency, and low e-coatings (also known as electrodeposition coating), which is used as a protective primer, determine the cost. Installing energy-efficient windows can save you between 7% and 15% annually in energy costs. To determine if energy-efficient windows are worth the investment, you’ll need to think about how much you spend on energy costs now, how many windows you have, and how long you plan to live in your home.

Here’s a quick breakdown of various factors that impact the cost of energy-efficient windows and what you can expect to pay for each.

Number of PanesCost
Single Pane$100 – $350 per window
Double Pane$400 – $900 per window
Triple Pane$500 – $1,800 per window
Type of GlassCost
Insulated$10 – $20 per square foot
Double-Glazed$3 – $6 per square foot
Tempered$12 – $14 per square foot
Low e-coatings$300 – $1,000 per window
Tinted$7 – $110 per square foot
Laminated$10 – $20 per square foot

Number of Panes

The number of panes that a window has determines just how energy-efficient it will be. In general, windows with fewer panes cost less, but they aren’t as efficient as windows with multiple panes. 

  • Single pane: This is the most affordable type of window because it uses less glass. However, it’s also the least energy-efficient option. In general, you’ll pay between $100 and $350 per window, but you won’t see lower energy bills. 

  • Double pane: Double-paned windows offer better insulation than single-pane windows because of a layer of nontoxic gas like argon or krypton that’s trapped between the panes. They cost between $400 and $900 per window on average.  

  • Triple pane: Triple-paned windows function similarly to double-paned windows but offer even better insulation thanks to an extra layer of glass and protective gas. You’ll pay between $500 and $1,800 per window on average for three panes. 

Type of Glass

There are many different types of window glass and just a few are ideal for reducing energy costs. 

  • Insulated glass: This type of glass is ideal for homeowners in warm climates because it’s finished with a special glaze that reduces sun glare and keeps home interiors cool on even the hottest of days. On average, you’ll pay $10 to $20 per square foot of this window material. 

  • Double-glazed: This type of glass provides insulation from both noise and weather and it’s relatively affordable compared to other energy-efficient options at $3 to $6 per square foot on average. 

  • Tempered glass: This is the strongest type of glass which means it’s well-protected from elements like wind, debris, and intense weather. It costs $12 to $14 per square foot of material on average. 


These extra window treatments may cost a lot up front, but they can save you on energy costs in the long run

  • Low e-coatings: Though low emissivity coatings can be pricey to install, they can also reduce heat loss by as much as 50%. Expect to pay between $300 and $1,000 per window for this extra feature. 

  • Tinted: Tinted glass can also reduce the amount of heat that enters and leaves your home, as well as reducing sun glare and blocking out harmful UV rays. This option costs $7 to $110 per square foot

  • Laminated: Laminated glass is functionally similar to double-glazed glass, but it’s a bit more expensive because of a few additional properties, like providing protection from moisture. This option typically costs between $10 to $20 per square foot.

Cost to Replace Window Glass

If you don’t need to replace the whole window and just need to replace the glass, plan to spend about $270. A glass installer charges between $50 and $75 per hour, and glass typically costs $3 per square foot. Keep in mind that these prices don’t account for window frame and trim replacements but do include the cost of a new window sash. 

Additional Cost Factors

Along with all the different parts and labor that are required to replace a window, there are a few tangentially related factors that can also affect the size of your final bill. 

Structural Repairs

In some cases, window replacements also reveal the need for greater, structural repairs in a home. For example, any cracks in the drywall or stone masonry that might have formed from one window to the next will require additional expenses and labor to properly and safely repair. 

Insulation and Weatherproofing 

Though windows don’t need to be insulated or weatherproofed to function properly, this kind of addition will save you money on both repairs and energy costs in the long run. In general, these kinds of treatments range from $3 to $20 per square foot on average. 


Although many professional contractors include the price of old window removal and cleanup in their cost of the entire project, some may charge an additional fee. In these cases, expect to pay an additional $55 to $65 per hour of extra labor. 

Hiring a Professional vs. DIY Window Installation

If you have a simple single window replacement, you may be able to handle the project on your own. If you'll be replacing multiple windows or installing a custom or complex window it likely makes sense to hire a window replacement installer near you. Hiring a professional will help you avoid issues involving mold, code regulations, cosmetic damage, and structural issues.

Labor Costs

Labor typically costs between $50 and $65 per hour with most window installations totaling between $100 and $300 per window for a simple installation, and more complex jobs costing $600 or more in labor, per window.  

Signs That Your Windows Need to be Replaced

Before you tally replacement costs, be sure to inspect your existing window frames for damage or rot. If the window's frame is soft to the touch, cracking, or showing signs of wear, it will need to be replaced. If it's still solid, you can simply install new glass and save money. Check to see if your windows are still under warranty.


Will replacing my windows change my current warranty? 

Before you replace your windows, you’ll want to check your specific home warranty to understand how it might be impacted. Many home warranties don’t cover windows at all, while some have specific clauses about what they will and will not cover and what will void the warranty. 

Should I replace just a few windows or all my windows at once?

While you don’t have to replace all your windows at once, doing so will likely save you money in the long run. Replacing all your windows at once will often save you money as installers generally quote a flat price for the job and their overhead remains the same for a partial or full day's work. Additionally, from a curb appeal and home value perspective, having matching windows that all look and perform the same is appealing. If you do plan to replace just some of your windows, it’s recommended that you replace no less than five to eight at a time.

What are the most energy-efficient windows?

Energy Star certified widows are the most energy-efficient windows on the market. Energy Star certified windows lower household energy bills by an average of 12% annually nationwide. 

What is the best time of year to replace windows?

There are advantages and disadvantages to replacing your windows in each season. Typically, demand for window replacement spikes in the spring and summer, as many people are concerned about replacing their windows in colder months. While spring or summer window replacement will certainly mean you don’t have to deal with cold drafts during the project, there will also likely be a longer waitlist and you may end up paying more. Choosing to replace your windows in the fall or winter, when demand is down but you might have to deal with a cold breeze, often means that your project will be completed more quickly and you’ll pay less than you would in warmer months. 

How often do I need to replace my windows?

 While windows each have their own natural lifespan based on materials, installation, and maintenance, most properly installed and maintained windows will last between 15 and 20 years. No matter how old your windows are, some signs that it’s time for a replacement include:

  • The room feels drafty

  • The window glass is foggy

  • Your energy bills are high

  • Your windows don’t open or close properly

  • Your window frames are soft

  • Water is seeping in

  • The look of your windows feels out of date

What is the cost to replace windows in an older home?

In general, it’s no more costly to repair windows in an older home than it would be to replace the windows of a similar size and material in a newer home. In older homes, however, you may be more likely to run into additional problems during the replacement that you’ll need to repair. These might include the need for structural repairs, insulation, or waterproofing.
