Factors That Affect Window Replacement Costs

Homeowners should consider several factors when planning for a windows replacement project. Your new window’s functionality, features, and construction play a part in which window option works best. You should also consider energy-efficient framing material, glass types, and Energy Star-certified products to help lower your energy costs. Your selected window brand and project size could also lead to additional savings and rebates. To help you make an informed decision, we’ll explain how each of the following factors will affect your windows budget:

  • Window type
  • Glass type
  • Energy efficiency
  • Framing material
  • Installation labor
  • Window brand
  • Number of replacement windows

We’ll also cover how any additional cost factors, such as your window location and home’s age, could influence your final costs.


How Much Do Different Types of Windows Cost?

Different types of windows are more expensive than others. Below are the most common window types and their average costs.

  • Arched ($200–$1,100): Arched windows are rectangular with a semi-circle at the top. Their shape allows more natural light into your home and may serve as a focal point for your home’s design.
  • Awning ($100–$1,000): These windows have hinges on the top and open by pushing out the bottom. This design allows for ventilation and rain protection. Awning windows are often placed higher on walls for privacy.
  • Bay and bow ($400–$5,500): A bay window typically includes three large glass panes set in an angled frame that protrudes from the house. Bow windows are similar but have a more curved design. Because of their size and complexity, these windows are typically quite expensive to replace.
  • Casement ($200–$2,000): Casement windows use a hand crank to open like a door, typically from left to right.
  • Double-hung ($250–$3,000): A double-hung window opens from the top or bottom for maximum ventilation. These are slightly more expensive than single-hung windows. 
  • Egress ($300–$830): Egress windows are specialty windows designed for your home’s basement. Safety codes often require them for habitable spaces in a basement or attic, as they’re intended as emergency exits.
  • Glass block ($60–$840): Glass block windows are most common in bathrooms because they let in light while offering privacy.
  • Picture ($150–$1,000): Picture windows, sometimes called fixed windows, are made of one glass sheet in a frame that doesn’t open. These windows often have unique sizes and shapes, so you might need a custom option.
  • Single-hung ($175–$2,800): Single-hung windows have a movable bottom sash and a fixed upper sash. They make great options for bottom-floor installations due to their restricted operation.  
  • Skylight ($150–$2,000): Skylight windows are expensive to replace because they’re difficult to install. They’re placed on your home’s ceilings to provide natural light in areas it may not otherwise reach, such as hallways and bathrooms. 
  • Sliding ($150–$800): Sliding windows open horizontally to the left and right on a fixed track. 
  • Storm ($100–$400): Storm windows are additional glass panes installed inside or outside existing windows to protect them from inclement weather and provide further insulation. They can be permanent or removable. Homeowners typically opt to protect all of their home windows, costing around $5,000.

How Much Do Different Glass Types Cost?

A window’s glass type determines its energy efficiency and in turn affects your energy bills. Energy-efficient glass reduces a window’s heat transfer, lessening the amount of energy needed to keep your home warm in winter and cool in summer. Different glass types also help reduce noise, add privacy, and protect your home from the elements. 

Windows come with different pane or glazing options. Glazing affects the window’s overall efficiency and climate suitability. The more panes a window has, the better its energy savings and noise reduction. Single-pane windows are the most basic window glazing type. They use a single glass layer and don’t provide insulation or energy efficiency. However, they cost only $100–$350 each, making them the best option for homeowners on a strict budget.

Double-pane windows are more energy-efficient because they use two glass panes with gas trapped in between. Common options include krypton or argon gas. These gasses are nontoxic, colorless, and odorless. They act as insulation, helping to block frigid cold or sweltering heat from entering your home and preserving your interior temperatures. 

According to the Efficient Windows Collaborative, double-pane windows are the most popular choice among homeowners because they are both inexpensive and energy efficient. Double-pane windows cost $280–$1,500 each. For additional protection, you can install triple-pane glass windows with three glass panes. These are the priciest option, costing $300–$2,700 per window.

Homeowners can add specialty glass for added safety and privacy. Laminated glass, which contains resin for added durability, is up to five times stronger than normal glass and provides added protection from forced entries. 

Tempered (or safety) glass provides even better protection than laminated glass. It offers additional protection from debris caused by inclement and extreme weather. 

Frosted glass is semiopaque, meaning sunlight can travel through your window while blurring the view into your home. 

Cost by Window Glass Type

Replacing window glass costs $300–$1,000 on average but can be higher depending on window size. Read about the average material costs to replace each window glass type below.

Glass TypeAverage Cost
Single-pane glass$100–$350
Laminated glass$125–$2,750
Tempered glass$150–$3,000
Double-pane glass$280–$1,500
Frosted glass$300–$700
Triple-pane glass$300–$2,700
Low-e glass$350–$2,680
Argon-filled glass$375–$2,720

How Much Do Energy-Efficient Options Cost?

Installing Energy Star-certified windows will improve your home’s energy efficiency and maximize energy savings. These products are recommended by the U.S. Environmental Protection Agency (EPA) for their energy efficiency. These products are also tested independently by the National Fenestration Rating Council (NFRC), a non-profit organization that grades windows’ insulation and efficiency performance. The NFRC also has a website with exact specs for every window manufacturer.

According to Energy Star, using its certified windows will lower your household energy bills by an average of 12% per year. Upgrading non-certified single-pane windows will save you $101–$583 per year and $27–$197 per year for double-paned. Energy Star products carry energy performance rating designations, making it easier to select the best options for your home’s needs. 

Energy-Efficient Window Treatments

Homeowners can also opt for glass with special coatings that block ultraviolet (UV) rays. Low-emissivity coatings (low-e) help control how heat moves through window panes. Low-e exterior glass coatings prevent heat from entering your home without blocking sunlight. The UV blocking also protects floors, furniture, and art from sun bleaching. In fact, the Department of Energy states that although windows with low-e coatings cost about 10%–15% more, energy loss reduction improves by 30%–50%.

Tinted windows are a cheaper alternative to low-e windows. They use solar window film to block UV rays. They’re similar to car window tinting but are less noticeable and don’t hinder your home’s aesthetics.

How Much Do Different Window Framing Materials Cost?

Window framing material is exactly what it sounds like: the structure between the window’s glass and the walls around it. This material affects the window’s appearance, cost, energy efficiency, and maintenance level. 

  • Aluminum ($75–$400): Aluminum is a strong and lightweight metal. Aluminum windows are popular because they resist bending and warping. Unfortunately, it’s not a good insulator, thus not a particularly energy-efficient option. 
  • Composite ($300–$1,200): Composite frames are a blend of wood fibers and polymers. Composite windows are as durable and energy-efficient as vinyl but a bit pricier than wood.
  • Fiberglass ($500–$1,500): Fiberglass window frames are as energy-efficient as vinyl and as sturdy as aluminum. They can also mimic painted wood. However, they’re one of the most expensive window replacement materials. 
  • Vinyl ($100–$900): Vinyl window frames are the most common option because they’re durable and affordable. Vinyl is a good insulator, making it energy-efficient. Vinyl frames are also the most low-maintenance material, though not necessarily the most attractive.
  • Wood ($150–$1,500): Wooden windows have a classic look. Wood doesn’t expand or contract with heat, and you can repair individual frame parts rather than replace the entire window. However, you may be stuck with multiple future repairs since wood can crack, peel, and warp.

Cost by Frame Material

Below is a breakdown of window frame costs for material only.

Retrofit Replacement Cost vs. Full-Frame Cost

Homeowners can keep replacement window costs low by opting for retrofit installations. This type of installation uses the existing window frame and trim and only involves removing the window sash. A retrofit installation can reduce window installation costs by up to 20%. If your current window frame and trim are in excellent condition, this replacement option will work best. 

A full-frame installation could double the cost per window. In this replacement process, the window sash, trim, and frame are removed and replaced with new parts. The window frame and trim must then be stained to match the existing trim. A full-frame replacement is required if your current trim and frame are in poor condition. See a breakdown of window parts below, as illustrated in our How To Replace a Window article.

What Are the Labor Costs for Window Replacement?

Along with the actual window cost, you should also factor in the labor cost. We recommend using a professional installer for most projects. Window installation experts have experience with proper window installation and can identify any performance issues. 

Professional installers are familiar with local codes and regulations, ensuring your new windows meet all standards and requirements. Window installers provide a faster installation process and back their jobs with workmanship warranties. Out of the 71% of our surveyed respondents that worked with a professional installer, 58% said they wanted to protect their investment with a warranty. 

Homeowners can expect to pay an average of $100–$300 per window. More complicated installations (such as oversized and specialty windows) can increase labor costs by $600 or more per window. While a standard installation takes about an hour, large jobs could last six hours or more.


What Are Window Replacement Costs by Brand?

Replacement window costs vary widely depending on your chosen type, material, and customizations. You’ll pay top dollar for premium brands, such as Andersen or Pella, and high-end styles and materials. Homeowners could also choose replacement-only window installers, such as Renewal by Andersen, to lower their overall investment. 

Request quotes from installers to get estimates for your window replacement project. Below is a list of some of the best window brands and their average prices.

Window BrandWindow Frame MaterialCost
Andersen WindowsAluminum, composite, fiberglass, vinyl, wood$500–$3,000
Castle WindowsAluminum, Fiberglass, vinyl$300–$600
Champion WindowsAluminum, vinyl$350–$800
Harvey WindowsVinyl, wood$500–$1,350


How Much Does It Cost To Replace Multiple Windows?

Many window replacement companies offer discounts and savings when replacing several windows simultaneously. Therefore, many homeowners opt to replace all their home windows at once. Most windows are installed at the same time, so they often require replacement around the same time anyway.

Note that prices listed throughout this guide are per window. Your windows project will likely involve replacing multiple windows. We recommend working with a local contractor to create a full project budget in order to get an accurate estimate. According to our homeowners survey, 47% of respondents paid between $500 and $3,000 for their entire windows project. Keep this price range in mind when planning your window upgrades. If your project is larger, you may get a discount.


Additional Window Replacement Cost Considerations

In addition to the window type, frame material, and labor, the following factors can impact your window installation cost.

  • Home age: A home’s age can increase labor costs, as older homes sometimes have non-standard window sizes or structural issues that require more careful installation.
  • Insulation/weatherproofing: Additional insulation, such as unique spacing systems or weatherproofing, will increase your cost per window. 
  • Location: Ground floor windows require less labor to replace than basement or upstairs windows, decreasing installation costs.
  • Replacement versus new installation: Replacing your home’s windows is less expensive than installing them during new construction.

How To Know It’s Time To Replace Your Windows

In many cases, you can tell when windows should be replaced. You’ll see signs of worn window frames, cracked panes, or feel air leaks around the window. Other signs, such as elevated noise or higher energy bills, could also indicate a need for new windows. Below are the most common signs you need to replace your windows.


If you notice water droplets accumulating on the window’s surface or in between the window panes, the seal might be broken. Both moisture and air can seep through a broken seal. 

Damaged Frames

Damaged or decaying frames cause moisture buildup, leading to water damage, rotting, and mold. This problem is especially common with wooden windows. If the glass is still in great shape, you may be able to replace just the window frame rather than the whole window

Difficult to Operate

If you have difficulty opening or closing your window, it may be time for a replacement. This issue occurs with improper installation, a warped or rotted window frame, or settlement in your home’s foundation. Windows that don’t close properly might also not lock, creating a safety issue for you and your family. 


If your home struggles to maintain a comfortable temperature, check to see if any drafts are coming from your windows. If so, your energy bills could climb to compensate for the irregular internal temperatures. The Department of Energy estimates that homeowners could achieve 5%–30% in potential annual energy savings by reducing drafts. Properly sealed new windows will eliminate chilly drafts during winter and expel excess heat and humidity in summer.

Higher Energy Bills

Higher monthly utility bills might indicate the need for window replacement. Twenty-four percent of our survey respondents noted unexplained energy cost increases, motivating them to replace their windows. Faulty window insulation and seals would cause your HVAC to work overtime, increasing energy bills. Installing new windows ensures your home remains comfortable year-round and helps lower heating and cooling costs

Noise Infiltration

Old windows struggle to provide adequate sound insulation and absorb external noise. Although some soundproofing window solutions may help reduce the noise, they may only partially resolve the problem if the window is too old or damaged. New windows, especially ones with multiple panes, absorb outside sounds more efficiently.



How To Save Money on Replacement Window Costs

You have several options to lower your window replacement costs. Thanks to the 2022 Inflation Reduction Act, homeowners can receive a federal tax credit for installing Energy Star-certified windows and skylights. According to Energy Star, you can claim up to 30% of installation costs for a maximum credit of $600. This credit applies to your primary residence and is available from January 2023 to December 31, 2032. 

Check with your local utility company for any rebates and incentives available. These credits are limited to Energy Star or energy-efficient windows that have been professionally installed. You may also receive rebates from the window installer companies. Some states offer tax credits and rebates for energy-efficient home improvements, including windows. You should check the Database of State Incentives for Renewables and Efficiency (DRISE) for available incentives in your state.

Homeowners could also choose affordable window replacement options and styles, such as vinyl double-hung windows, to keep budgets to a minimum. Although they don’t offer the visual appeal of wood or fiberglass, they provide good energy efficiency and affordability.


Things To Ask Yourself Before Buying Replacement Windows

As you begin planning your window replacement project, remember that each aspect of the window’s design, material, and placement will affect your overall costs. Below are some questions to help you decide on your replacement windows’ major features, functionality, and design elements. 

When deciding on window type, you should consider:

  • How do I need the window to function?
  • What size window is being installed?
  • Do I want the windows for style, energy efficiency, or both?
  • What room are the windows being installed in? 
  • How will they look in that room?

When choosing framing material, ask yourself:

  • Can I repair the existing frame, or do I need frame replacement?
  • Do the frames match my home’s style? 
  • What are the typical weather patterns around my home? 
  • How much maintenance do the frames require?

When selecting glass type, consider the following: 

  • Do I need more energy-efficient glass to improve my home’s performance?
  • Do I need weather-resistant glass?
  • Do I need noise-reduction glass?
  • Do I need windows tailored to safety and privacy?


Our Conclusion

On average, window replacement costs around $300 per window. This price increases after selecting your preferred style, framing materials, and efficiency preferences. We recommend contacting at least three window companies to compare quotes, products, and warranty options to find the right windows for your home.
