Casement windows are a popular choice for homeowners looking for better ventilation and a clean, modern look. Expect to pay $500–$1,000 per window installed, though costs can go higher depending on size and materials.
In our recent survey of 1,500 homeowners, 46% had at least one casement window installed during their window project. On average, those who chose casement windows spent $11,304 on installation — though your final cost will depend on the number of windows, labor rates in your area, and whether you’re doing a full-frame replacement or a simpler retrofit.
Casement windows offer great airflow and an unobstructed view, but they aren’t the cheapest option. We’ve gathered expert insights and real pricing data to break down costs, pros and cons, and key factors to consider before your next window upgrade.

Average Cost of Casement Windows
A casement window is a side-hinged window that swings outward like a door, typically operated with a crank or lever. Unlike double-hung or sliding windows, which open by moving up, down, or side to side, casement windows provide a full, unobstructed opening for maximum ventilation.
On average, casement windows cost $500 to $1,000 each. Depending on your specific needs, your casement window prices may fall below or well above that range.
| Cost Range | Average Cost Range |
| Low-End Cost Range | $250 – $475 |
| National Average Cost Range | $500 – $1,000 |
| High-End Cost Range | $1,100 – $1,850 |
Casement Window Replacement Costs: Insert Vs. Full-frame
Before diving into the cost factors of casement windows, it’s important to determine whether you need a window insert replacement or a full-frame replacement. Full-frame replacements involve removing the entire window down to the rough opening. These window replacement costs will be closer to what you’d pay for new construction windows.
“Retrofitting new windows into existing frames is generally less expensive than full-frame replacements, which involve removing the entire existing window and frame and installing new ones,” said Robert Schindler, vice president of North Wilkesboro-based Window World. This article covers window insert replacements, which involve securing a new sash and frame into the existing window opening.
A reputable window replacement contractor will likely decide between full-frame and pocket replacement, depending on the condition of your window sill and frames. We recommend maintaining your windows frequently to help avoid more involved installation procedures.

What Factors Affect the Cost of Casement Windows?
Your casement window costs won’t always fall within the national average cost range. The following factors can fluctuate your final price by hundreds or even thousands of dollars.
Cost of Casement Windows by Size
The size of your casement windows will significantly influence their cost. Larger windows require more materials and labor for installation, resulting in higher prices. Standard window sizes cost less than custom sizes, which is worth noting if you have specialty windows needing replacements.
The table below displays prices for casement windows of various sizes and materials* to help you understand cost trends.
| Casement Window Size | Vinyl Average Cost | Wood Average Cost |
|---|---|---|
| 2’ X 2’ | $440 | $615 |
| 2’ X 3’ | $470 | $700 |
| 2’ X 4’ | $565 | $750 |
| 2’ X 5’ | $585 | $830 |
| 2’ X 6’ | $650 | $900 |
| 3’ X 5’ | $785 | $965 |
| 3’ X 6’ | $915 | $880 |
| 4’ X 3’ | $960 | $1,190 |
| 4’ X 4’ | – | $1,270 |
| 4’ X 5’ | – | $1,400 |
| 4’ X 6’ | – | $1,535 |
| 5’ X 3’ | – | $1,185 |
| 5’ X 5’ | – | $1,340 |
| 7’ X 4’ | – | $1,760 |
| 7’ X 5’ | – | $2,120 |

Cost of Casement Windows by Number of Panels
In addition to the overall size of your casement windows, you must determine how many panels or lites you need. Choosing multi-panel casement windows raises your price because you’re essentially installing multiple windows. However, you may save by getting the full window project out of the way at once. Plus, the panels often come within a single frame, allowing for quicker, easier installation.
See potential prices for different casement window configurations:
| Casement Window Panels | Average Cost |
|---|---|
| Single | $440 – $880 |
| 2 lite | $900 – $1,000 |
| 3 lite | $1,350 – $1,500 |
| 4 lite | $1850 – $2,251 |
| 5 lite | $2,600+ |
| Picture window with casement flankers | $1,880+ |
A picture window with casement flankers includes a fixed center window with operable casement windows on each side. This layout utilizes the benefits of both window types for true home improvement. You get natural lighting and a scenic view of a picture window, plus the enhanced airflow of casements.
Cost of Casement Windows by Frame Material
Frame material is one of the most significant cost factors for any type of window. The most common frame options for residential casement windows are vinyl, aluminum, and wood, though some brands offer premium options like composite and fiberglass frames.
Wood tends to be more expensive due to its costly sourcing and craftsmanship, while vinyl and aluminum offer more affordable alternatives with excellent durability and low maintenance requirements. However, aluminum windows may not be as good of an investment as high-end vinyl or wood windows.
Higher-quality window frames, such as vinyl or wood, can last decades before they need replacement. They’re also more energy efficient than aluminum, which helps reduce your monthly energy bills. Insulated vinyl window frames are the most affordable and energy-efficient, according to Mike Peck, the vice president of installation at Leaf Home in Akron, Ohio. Just know that vinyl isn’t always the best choice for extremely hot climates, as it can bow or warp under constant high temperatures.
Though fiberglass and composite frames are less common for casement windows, they offer unique benefits at a much higher price point. Composite frames, made from a resin-fiberglass mixture, combine the long-lasting durability of vinyl with the sophisticated look of wood. Meanwhile, fiberglass frames can be up to eight times stronger than vinyl ones, making this material an ideal choice for severe climates. However, fiberglass windows are typically the most expensive due to costly manufacturing processes and lower availability.
Here are some price range approximations for popular window materials:
| Casement Window Frame Material | Low-End Cost | High-End Cost |
|---|---|---|
| Vinyl | $450 | $800 |
| Aluminum | $585 | $1,075 |
| Wood | $600 | $1,550 |
| Composite | $700 | $1,800 |
| Fiberglass | $700 | $2,000 |

Cost of Casement Windows by Glazing
Glazing has the power to improve the energy efficiency, performance, and functionality of casement windows. However, those layers of glass also have the potential to impact your final bill.
Single-pane windows are undoubtedly the cheapest option but provide the fewest benefits. Meanwhile, double-pane windows and triple-pane windows provide superior insulation and noise reduction at a higher price. Before settling on a casement window glazing option, consider which will fit your budget and home improvement needs.
| Casement Window Glass Type | Average Cost |
|---|---|
| Single-pane | $200 – $425 |
| Double-pane | $450 – $1,000 |
| Triple-pane | $1,000+ |
Glass Upgrades
You can make your casement windows more energy efficient by upgrading their glass with different tints or a low-emissivity (Low-E) coating. Window manufacturers typically fill their double-pane and triple-pane windows with argon or krypton glass. These features improve the window’s energy efficiency and sound-reducing capabilities. Tempered and laminated glass are other common upgrades that make your glass more impact-resistant. Glazing features like Low-E coatings and UV-resistant tints can tack $5 to $15 per square foot to your window costs.
Cost of Casement Windows by Brand
Countless brands on the market offer casement windows, which is why prices can vary wildly. Below, we’ve listed some of the best window companies and potential cost ranges of casement windows below:
| Casement Window Brand | Average Cost |
|---|---|
| Universal Windows Direct | $400 – $600 |
| Simonton | $450 – $750 |
| Pella | $550 – $800 |
| Window World | $550 – $850 |
| Window Nation | $550 – $850 |
| Castle Windows | $550 – $850 |
| JELD-WEN | $500 – $900 |
| Marvin | $600 – $950 |
| Champion Windows | $700 – $1,000 |
| Renewal by Andersen | $900 – $1,200+ |
Although it’s tempting to go with the cheapest window replacement company, consider the additional benefits a company offers for its higher pricing. Maybe you’ll pay more for a certain brand but get a better warranty, higher quality window, and full-service installation. These service upgrades can make the higher price worth it down the road.
Additional Costs of Casement Windows
While preparing your budget for new casement windows, you should make some extra room for labor fees, customizations, and any other accessories you’re considering. Understanding these additional cost factors ahead of time can help you make an educated decision.
Labor and Installation
According to RSMeans, casement window installations generally require one to three carpenters, depending on the project’s scope. Single-panel casement window installations that require one worker may add $39 to $63 per hour to your price. More complex installations for multi-panel casements or bay windows containing casements may add $117 to $190 per hour to your final bill.
Location in the Home
The area of your window installation may affect your costs. Installations on the second and third floors sometimes require lifts or scaffolding to reach the project site, adding to your overall labor fees.
Customization
Designing tailor-made casement windows can benefit your home’s curb appeal but also significantly increase the final cost. Before tweaking your windows (from their exterior finishes to the hardware), consider whether it’s worth the price hike.
Hardware Accessories
Casement windows are functional because of their hand cranks and locks. While hardware is typically included in the initial price of a casement window, custom finishes and premium options will cost more. If you need to replace hardware down the road, expect to spend around $15 to $45 per piece.
Number of Replacement Windows
Replacing more windows will likely result in a more expensive invoice. According to our survey respondents, those who replaced one to five casement windows paid an average of $12,072 for their replacement project, and respondents who replaced six to 10 windows paid an average of $15,215.
However, note that window manufacturers may provide discounts for bulk orders. If you can’t decide between replacing all the windows in a room instead of one or two, speak with a sales representative to see how much you can save by buying in bulk.
How Does the Cost of Casement Windows Compare To Other Window Types?
Casement windows are typically a mid-range cost option, similar to double-hung windows. However, your costs will be higher if you combine casement windows with other window types. Picture windows with casement flankers typically start around $1,800. Architectural windows can double or triple that price. For example, we found a $5,358 estimate for a bow window made of casement window panels.
If you combine multiple window styles, budget for higher costs. The project will be bigger, with more moving parts and installation requirements.
Here’s how casement windows compare to other popular window styles:
| Window Type | Low-End Cost | High-End Cost |
| Storm | $100 | $400 |
| Single-hung | $200 | $400 |
| Double-hung | $430 | $915 |
| Awning | $430 | $830 |
| Egress | $300 | $1,500 |
| Glass block | $500 | $1,000 |
| Skylight | $500 | $2,000 |
| Picture | $700 | $1,300 |
| Bay | $1,000 | $7,000 |
| Bow | $2,000 | $4,000 |
Is DIY Worth the Cost Savings of Installing Casement Windows?
Installing your own casement window with the proper tools, skills, and expertise is possible. However, window installation can be challenging, as it requires precision and close attention to ensure a secure and weatherproof fit. Without these things, your new casement window may be more damaging than beneficial for your home.
Our team shadowed a Renewal by Andersen installation crew in June 2024 in Charlotte, North Carolina. During the ride-along, we first noticed that the installation took three team members—one inside the home and two outside—to complete. We also noted that the installers took precise measurements throughout the process and used high-quality spray foam insulation to help protect the windows from the elements and ensure utmost energy efficiency.
“If you [install windows] yourself, you can buy them from a contractor, but the manufacturer will know and void the warranty if they are not installed by a certified, approved contractor,” said Rick Andronicos, owner of United Builders in Southern California
Our top-rated window brands offer lengthy labor warranties that help cover installation costs if your windows fail prematurely. DIYers don’t have that luxury—they’ll need to pay out of pocket for any future repairs. This is why we suggest hiring a professional installation company for your window replacement project. A crew of certified installers can handle the entire process, from old window removal to cleanup, bringing the knowledge and equipment needed to perform a meticulous, high-quality installation. If anything goes wrong after the crew leaves, you’ll have a customer support team and window warranty to help you out.

Are Casement Windows Worth It for Your Home?
Casement windows generally cost between $500 and $1,000. However, costs can increase depending on your chosen frame material, window size, and brand. You can save money on casement windows by selecting standard sizes, fewer panels, and cheaper frames. If you decide on a custom window with specialty hardware, glass coatings, and grilles, prepare for a higher price tag. That said, new casement windows can be an excellent investment that increases the curb appeal of your living space. Although they cost more than non-operational window types, their added functionality may better suit your needs.

FAQs: Cost of Casement Windows
Picture windows cost more than bigger than casement windows, which yield higher starting prices. However, picture and casement windows of the same size may have similar prices.
In some cases, a casement window may cost more because it requires operational features like hardware, muntins, locks, and additional lites, while the picture window only has one large glass pane. When choosing between picture and casement windows, you should likely account for the window size as the largest determinant of price.
According to Thompson Creek Window Company, casement windows are one of the safest window styles for your home. Once you close and latch them, these windows can’t be opened from the home’s exterior, even with a crowbar. They feature durable locking mechanisms and weathertight seals, making them hard to penetrate and keeping out intruders and outdoor elements.
Casement windows aren’t the cheapest type of window you can buy. The prices of awning windows often fall within a lower price range, starting at around $300. Double-hung and single-hung windows are also lower-cost window options, starting at around $400 per window.
Casement windows are one of the most energy-efficient windows, despite their ability to open and close. They’re more energy-efficient than double-hung windows because they don’t require a sliding track for opening. Tracks wear down over time, leading to potential air leaks and water seepage. Casement windows open on a hinged side and close tightly to lock and seal.
For the most energy-efficient casement window, we suggest shopping for options certified by ENERGY STAR and the National Fenestration Rating Council (NFRC).
There are a few common reasons for replacement, according to Kevin O’Donnell, owner and CEO of O’Donnell Roofing based in eastern Pennsylvania.
“People will often replace the windows in their home because they notice that they are getting cold or drafty, they want to improve the energy efficiency of the home, or they simply want to update the look of their windows,” said O’Donnell.
Here are some of the common signs that it’s time to replace your windows and the benefits of doing so:
- Damaged windows: Nearly 56% of homeowners in our survey who purchased casement windows replaced their old windows because of broken glass or damaged frames. Replacing damaged windows can make your home more comfortable and safe, as damaged windows can be a security risk. It may be possible to replace the glass rather than the entire unit if your window only has damaged glass.
- Rising energy costs: Besides reducing drafts, upgrading to new, energy-efficient windows can drastically reduce your monthly energy bills. The average homeowner can save up to $580 per year with an efficient window, said Mark Waddell, installation and application manager of Cornerstone Building Brands, New windows are eligible for up to $1,100 tax credits, he added.
- Outdated appearance: New windows are a significant investment, but the window replacement gives your home a facelift and improves curb appeal. 70% to 75% of his customers buy new windows for design reasons, estimated Jeff Ludy, owner of Houston Window Experts. A qualified window expert will advise on the best window styles and frame materials to improve your home’s look.
