A single-pane casement window starts at $224, while a bay window casement costs up to $3,600.* Rather than sliding up and down, casement windows have a hinge on one side and swing outward like a door. They typically open via a hand crank and are easy to operate. They also seal tightly when closed, keeping out drafts better than many other types of windows. Our guide details the cost of casement windows based on factors such as type and size, plus offers advice on the best installation options.

The window’s size, type, brand, and frame material have the biggest impact on cost.

  • Window type: Simple windows are less complex than windows with multiple frames or openings, and are thus easier and cheaper to install.
  • Window brand: Some window brands are more high-end than others.
  • Window size: The larger the window, the higher the cost.
  • Window frame material: Aluminum and vinyl casement windows cost much less than fiberglass or wood windows.

Cost by Casement Window Type

The simplest type of casement window has a single glass pane in a frame with a hinge on one side. You can also install double casement windows, which have two window panes that open like French doors.

Another popular configuration is a large, central picture window with a casement window on either side. Casement windows can also make up the angled side windows of a bay window. In general, casement window prices increase with the installation’s complexity.

Cost by Window Brand

Many leading window brands offer casement windows at various price points depending on frame material and energy efficiency features. Jeld-Wen specializes in cost-effective wood and vinyl casement windows with multiple grille patterns. Three of Andersen’s four product lines are available in the casement style, with vinyl, wood, or composite options. Pella offers the largest price range, including single-pane vinyl windows and double-casement windows framed in wood.

Cost by Window Size

Larger windows require more materials and are slightly harder to install, so they cost more than smaller windows. Standard-size windows cost much less than those with custom sizes and shapes. Here are some common casement window sizes and their typical price ranges.

Cost by Window Frame Material

As with most windows, casement windows are available with vinyl, aluminum, fiberglass, or wood frames. Each of these materials has benefits and drawbacks when it comes to price, durability, and energy efficiency.

Labor Cost

Professional installation typically costs between $30 and $50 per hour. Anything that increases the project time, such as difficult-to-access windows or complex installations, will increase this cost. Window installers tend to be busiest in spring and summer, so they may charge more for labor during this time. Window companies also cost more in areas with a higher cost of living or a very active housing market.

Additional Factors Affecting Casement Window Cost

The following considerations may also impact on your window project’s price, depending on the specifics.

Window Frame Replacement Type

Window replacement costs depend partly on whether you’re replacing the full frame. New construction windows come surrounded with nailing flanges (thin strips installed on a window’s exterior), so an existing home must be stripped of siding before the replacement can start. This is more expensive, around $150 to $1,000 in labor, though your new window will be weathertight. If you’re just popping an existing window out of the frame and installing a frameless replacement, expect to pay $150 to $300 per window. However, there’s a larger chance of air or water leaks with this replacement type.

Type of Gas in Window Pane

Window manufacturers use insulating, nonreactive gas to fill the space between double- and triple-pane windows’ glass. The most common type is argon gas, which greatly improves how well the window insulates.

Krypton gas is more insulating than argon but is substantially more expensive. It’s typically only used in triple-pane windows. An argon-filled casement window usually costs between $375 and $850, whereas a krypton-filled casement window costs between $525 and $1,190. Our research suggests that argon-filled windows are sufficient for homes in most climates, as krypton’s insulation factor is only modestly higher. 

Number of Glass Panes

As with most residential windows, casement windows can have one, two, or three glass layers in each pane. Single-pane windows are the least expensive, but they’re also the most breakable and least energy-efficient. Double-pane windows are far more efficient since the heat that hits the exterior glass has less chance of transferring through to your home’s interior. 

Triple-pane windows further increase this efficiency, and both types are harder to break. Nearly all ENERGY STAR-rated windows are double- or triple-pane and cost more than single-pane windows.

Glass Coatings

The most energy-efficient windows don’t have clear glass panes. Instead, the glass is coated or treated with glazing that prevents excess heat from transferring through the window, in some cases without reducing visible light.

  • Reflective coatings are applied to the window’s exterior and reflect some light to prevent glare and increase privacy.
  • Low-emissivity (low-e) treatments consist of a thin coating of metal oxide that filters out certain wavelengths of infrared and UV light. This reduces heat transfer, lowering energy loss by 30% to 50%, according to the U.S. Department of Energy (DOE).
  • Spectrally selective coatings block even more heat than low-e glass, reducing home heat loss by up to 70%, according to the DOE.

Professional vs. DIY Casement Window Installation

Some homeowners may want to save money on labor by installing casement windows themselves. Here’s what you need to know about this home improvement project.

Professional Casement Window Installation

You’ll pay more to hire a professional window installer, but the job will be done quickly and efficiently. Windows are important to your home’s energy efficiency. Leaky or poorly insulated windows force your heater or air conditioner to work overtime to maintain a comfortable temperature. This increase in your utility bills will likely outweigh any short-term savings a do-it-yourself (DIY) installation provides. Professional installation also offers more peace of mind and sometimes includes a workmanship warranty.

DIY Casement Window Installation

Installing windows yourself will save you money up-front, and it may be an option depending on your skill level and the project’s specifics. Look for the necessary tools and materials at a hardware store such as The Home Depot. A vinyl window installation on the ground floor will be the easiest to handle yourself. You’ll need to take accurate window measurements to ensure a secure installation.

Additionally, replacement windows are far easier to install than full-frame windows. Be sure to check your new windowswarranty: Sometimes the warranty will be void if the window isn’t professionally installed.

If you aren’t skilled at window installation or have concerns about voiding your warranty, we recommend hiring a professional.


How to Reduce Casement Window Installation Costs

You can reduce your total project costs with the following tips.

Choose affordable replacement windows, such as vinyl, for the best balance of price and efficiency.

Stick to simple window configurations for smaller windows.

Think long-term: Installing high-quality, energy-efficient windows costs more up-front but will save you money on utility bills over time.

Consider having casement windows installed during the offseason to save on labor costs.


How to Hire a Professional

Hiring a window installer is similar to hiring most other contractors. Here are some steps to take to find a reputable company.


Benefits of Casement Windows

Casement windows have several benefits over more common single- or double-hung windows. Here are a few.

Aesthetics

Casement windows let in more light because there’s no sash running across the glass’s center. You can add grilles or keep the glass surface plain to provide an unobstructed outdoor view.

Ease of Operation

Opening and closing sashed windows requires a decent amount of strength, height, and leverage because you’re working against gravity. Opening a casement window is as simple as turning a hand crank. This makes casement windows more accessible to people who may struggle to raise or lower a window.

Energy Efficiency

Casement windows close by pressing the entire sash against the window frame, so they’re less likely to leak air over time. Since casement windows open outward, wind also presses the sash against the frame, further tightening the seal. The DOE identifies casement and awning windows, which are hinged at the top and also open outward, as two of the most energy-efficient window designs.

Improved Airflow

Unlike sashed windows, casement windows can open to the window frame’s entire height for maximum ventilation. Additionally, the open window pane can direct fresh air into your home if the breeze is blowing the right way.

Low Maintenance

Casement windows are simpler to clean because they open so easily. You should be able to access the window’s exterior and interior by opening it to clean the window’s outer surface. A casement window’s screens will be on the window’s interior, meaning they can be easily removed for cleaning.

Potential Egress

Because the entire window frame opens, a large casement window can be used as an egress window in an emergency. Since basements must have egress windows to be considered bedrooms.


Our Recommendation

The best windows for your home depend on a number of factors, but casement windows have several benefits. We recommend casement windows in rooms where uninterrupted views and maximum ventilation are high priorities, or in homes where residents have mobility issues, as these windows are easy to open. They’re also highly energy-efficient and less likely to leak.
