What are Major Casement Windows Cost Factors?

Casement window prices are primarily affected by the following factors.

• Window size: Casement windows come in many sizes, with larger windows typically costing more. Your window dimensions will also depend on the frame material and manufacturer.
• Casement window type: Casement windows can swing inward or outward and have push or crank opening styles. They also come in different designs, impacting the total installation cost.
• Window frame material: Casement windows come in various materials, each with different price points.
• Brand: Several manufacturers sell casement windows ranging from low to high-end prices.

Casement Window Size

The bigger the casement window, the more expensive the project. Your window dimensions may vary slightly based on the frame material and manufacturer.

For example, most vinyl casement windows are 3.5–35.5 inches wide and 17–73 inches tall. Fiberglass windows are taller than vinyl, reaching 77.5 inches. Wood casement windows that contain aluminum are as tall as vinyl but wider than most other types at 17–59 inches. The biggest casement windows are up to 72 inches wide and 96 inches tall. Most casement window manufacturers offer custom window sizes, but these cost more and the return policy may be different. 

A small 24-by-36-inch casement window costs $262. Higher-end frame, glass, and glazing choices can push the price to $354. Large, high-end casement windows cost $626 for the window alone. Every casement window size has different material selections, which significantly affect the price.

Casement Window Type

The cost of installing casement windows depends on which type you choose. For example, there’s single frame, double frame, egress, and a picture window that contains casement flankers. It costs $224 for a single-frame casement window and up to $800 for a picture window with casement flankers.

Here are different casement window types:

• Single-frame casement window ($224–$370): A single-frame is a basic casement window design consisting of one frame. This type of window opens either inward or outward, depending on the window mounting.
• Double-frame casement window ($445 and $585): Double-frame, or French, casement windows use two panels that open from the middle with no center stile.
• Picture window with casement flankers ($600–$800): A flanker is a window that’s installed on the side of another window. It’s often used to let in more natural light. Picture windows are large and inoperable, but many homeowners add casement flankers to the sides of a picture window for better airflow.
• Egress casement window ($430–$1,300): Egress casement windows are side-hinged and work the same as standard egress windows, except they’re smaller. The primary purpose of an egress window is to allow easy escape in an emergency, so it must be large enough for a person to fit through.

Cost by Type

Casement Window Frame Material

Your chosen window frame material also affects cost.

Cost by Frame Material

Casement Window Brand

Several different window brands manufacture casement windows and even offer Energy Star products. Here are some popular casement window brands.

• Andersen ($348–$984): Andersen offers classic casement windows plus push-out, French, and a made-to-order series. Andersen’s warranties vary depending on the specific window series and components, and some are transferable if you sell your home.
• Jeld-Wen ($262–$625): Jeld-Wen sells casement windows across nine product lines, and homeowners can choose from various wood or vinyl materials. The company’s premier product is custom wood, available in five configurations. Lower-cost and midrange materials are available. Jeld-Wen’s warranties are based on the date purchased.
• Pella ($465–$505): Pella offers wood, vinyl, and fiberglass casement window frame materials, broken down into categories based on their style and quality. Pella offers mid to high-end casement windows with available warranties.

Cost by Brand

Casement Window Labor

How much you pay a professional to install your casement windows depends on the type of window frame material. For example, wood is heavier and takes more time to install, so installing wood frames is more expensive than vinyl. Labor costs also vary by geographic location, with prices typically higher in metropolitan areas.

Labor costs $150–$300 per window, plus an additional $60 to remove and dispose of the existing window frame.

DIY vs. Professional Casement Windows Installation

Homeowners often consider installing windows on their own to cut down on costs, but this comes with risks. Here are some things to consider when deciding whether to hire a professional or tackle the project yourself.

DIY Casement Window Installation

You’ll need the right equipment, supplies, knowledge, and experience to complete do-it-yourself (DIY) window replacement. Window installation involves the following steps:

• Prying out the old frame
• Measuring
• Cutting openings and fitting the new window frame
• Installing the window
• Ensuring the window is sealed properly

Professional Casement Window Installation

A professional window installer will have all the necessary tools and equipment to complete the job quickly. The installer will measure and fit the window, ensure it’s level, and create a watertight seal using putty or glazing. 

Here are several advantages to hiring a professional casement window installer:

• Knows how to create a watertight seal to avoid mold and moisture damage
• Helps with window placement in the house
• Avoids building code violations
• Aware of any necessary permits
• Has the experience to do a custom or complex window installation
• May provide warranties or guarantees on their work

Additional Casement Windows Cost Factors

The following factors can also impact your casement window project cost. 

Number of Glass Panes

The more glass window panes in your casement window, the higher the cost. A single-pane window is the least expensive—between $150 and $400—but these aren’t as common due to poor insulation. Double-pane windows cost $150–$600 and have an insulating layer between the panes. Triple-pane windows are the most energy-efficient but cost $400–$950. Homeowners can add a low-emissivity (low-e) glass coating and insulating gas, but this increases the price.

Glass Coatings

Coatings are a clear, microscopic film added to glass for various reasons. A reflective coating ($230–$500) reduces glare and heat transfer and offers additional privacy. A low-e coating ($250–$840) helps keep heat inside your home during winter and outside during summer. Spectrally selective coatings ($350–$850) are a type of low-e coating, but they’re typically used in hotter climates to help keep cooling costs low.

Gas-Filled Windows

A gas fill refers to gas pumped between glass panes to plug “thermal holes” and increase a window’s energy efficiency. Argon gas and krypton are the most common, costing $380–$850 and $530–$1,190, respectively. Argon requires at least half an inch of space between panes, while krypton needs one-fourth an inch of space.
