Cost of Egress Window

If you have a basement or lower-level living space, ensuring the safety and functionality of your home is paramount. Installing egress windows is a crucial step to meet building code requirements and provide a safe means of escape in case of emergencies.

This comprehensive guide will delve into the various aspects of egress window installation, including the cost, types of windows available, and important considerations to keep in mind.

Why Install Egress Windows?

Egress windows are not just a legal requirement; they also offer several benefits that can enhance the overall livability and value of your home. These windows provide natural light, ventilation, and improved aesthetics to basement spaces. Additionally, egress windows allow for the creation of an additional bedroom, which can significantly increase your home’s resale value. Most importantly, they serve as a crucial safety feature, providing occupants with a safe exit route in case of emergencies.

Understanding Egress Window Requirements

Before diving into the cost and installation process, it’s important to understand the specific requirements for egress windows. The International Residential Code (IRC) sets the standards for egress window specifications.

According to the IRC, egress windows should have a minimum width of 20 inches and a minimum height of 24 inches. The net clear opening of the window should be at least 5.7 square feet, with the bottom of the window sill no more than 44 inches above the floor. It’s essential to consult your local building authority to ensure compliance with specific regulations in your area.

Factors Affecting Egress Window Cost

Several factors influence the overall cost of egress window installation. By considering these factors, you can plan your budget effectively and make informed decisions. Let’s explore the key elements that contribute to the cost:

Labor and Permits

Labor costs and permit fees are significant components of the overall expenses. Hiring a professional contractor to handle the installation ensures a proper and efficient process. Labor costs can range from $40 to $100 per hour, depending on the complexity of the project. Additionally, obtaining the necessary permits is crucial to comply with local building codes and regulations. Permit fees typically range from $50 to $200 per permit.

Window Type, Size, and Customizations

The type and size of the egress window you choose will have an impact on the overall cost. There are various window types available, including casement windows, double-hung windows, in-swing windows, single-hung windows, and sliding windows. Each type comes with its own price range. Additionally, customizations such as glass quality, frame materials, and hardware selections can add to the cost.

Number of Windows

The number of egress windows you need to install will directly affect the total cost. Each window requires materials and labor for installation. While installing multiple windows may increase the overall cost, it can lower the cost per window due to economies of scale. It’s important to assess your needs and consult with professionals to determine the optimal number of windows for your space.

New Installation vs. Replacement

The nature of the installation, whether it’s a new installation or a replacement, will impact the cost. New installations involve cutting out the window frame and creating a window well if it’s a below-ground basement window. This process requires additional labor and materials, resulting in higher costs. On the other hand, replacing existing windows that do not meet code requirements may require alterations to the frame or well, but it is generally less expensive than a new installation.

Location of the Window

The location of the egress window within your home can influence the cost. Attic and above-ground egress windows are typically less expensive compared to below-ground installations with window wells. Skylight egress windows fall within the mid-range of costs. Factors such as excavation, backfilling, and additional structural considerations can impact the overall expenses.

Types of Egress Windows

Egress windows come in various styles, each with its own advantages and considerations. Understanding the different types can help you choose the most suitable option for your specific needs. Let’s explore the common types of egress windows:

Casement Windows

Casement windows are a popular choice for egress windows. They feature a side-hinged design that opens outward, allowing for maximum ventilation and easy escape in case of emergencies. Casement windows are known for their energy efficiency and can add a touch of elegance to your space. The cost of casement egress windows ranges from $200 to $500, depending on the size and materials used.

Double-Hung Windows

Double-hung windows consist of two movable sashes that can be operated independently. They offer versatility, allowing you to open either the top or bottom sash for ventilation. Double-hung windows are generally more expensive than other types, with prices ranging from $250 to $500.

In-Swing Windows

In-swing windows operate similarly to casement windows but swing inward instead of outward. They are a suitable choice for older basements with small window openings. It’s important to note that small window openings may not meet egress window requirements unless they are modified to comply with size specifications. In-swing windows typically cost between $350 and $700.

Single-Hung Windows

Single-hung windows are similar to double-hung windows but only have one movable sash. They are a cost-effective option for first-floor or basement installations. The price of single-hung egress windows ranges from $100 to $400, depending on the selected brand and size.

Sliding Windows

Sliding windows consist of two separate panes of glass that slide horizontally. They are best suited for larger rooms due to the required size for egress compliance. Sliding windows typically cost between $150 and $700, depending on the size and materials used.

The Installation Process

Now that we have explored the various aspects of egress window installation, let’s delve into the step-by-step process involved in bringing these windows to life:

Step 1: Assess Your Needs

Begin by assessing your specific needs and requirements. Determine the number of egress windows needed, their locations, and the type of windows that best suit your space. Consider factors such as natural light, ventilation, and overall aesthetics when making your decisions.

Step 2: Consult with Professionals

Consulting with professionals experienced in egress window installation is crucial to ensure a smooth and successful project. They can provide expert advice, assess your space, and guide you through the process. Obtain multiple quotes to compare costs and choose a reputable contractor with a proven track record.

Step 3: Obtain Permits

Before commencing any construction work, it’s essential to obtain the necessary permits from your local building authority. Failure to comply with permit requirements can result in fines and delays. Your contractor can assist you in obtaining the appropriate permits.

Step 4: Prepare the Work Area

Clear the work area of any obstructions and ensure a safe and accessible environment for the installation process. Remove any furniture, coverings, or fixtures that may hinder the installation. Take necessary precautions to protect your belongings from dust and debris.

Step 5: Excavation and Preparation

For below-ground egress windows, excavation is required to create a window well. This process involves digging a hole around the window opening, ensuring proper drainage and stability. Backfilling the well with gravel or crushed stone provides support and prevents water accumulation.

Step 6: Window Installation

Once the window well is prepared, the installation of the egress window can begin. The process involves securing the window frame, ensuring a proper fit, and sealing any gaps to prevent air or water infiltration. Follow the manufacturer’s instructions and consult with your contractor to ensure proper installation techniques.

Step 7: Finishing Touches

After the window is installed, it’s time to add the finishing touches. This includes installing window wells covers, interior trim, and any additional accessories or features you desire. These finishing touches not only enhance the aesthetics but also provide added security and functionality to your egress windows.

Step 8: Inspection and Finalize

Once the installation is complete, schedule a final inspection with your local building authority to ensure compliance with all regulations and code requirements. Address any necessary corrections or adjustments before finalizing the project.

Additional Considerations

While the cost and installation process are crucial aspects of egress window projects, there are other considerations to keep in mind. These factors can help you make informed decisions and ensure the long-term functionality and satisfaction with your egress windows:

Maintenance and Upkeep

Egress windows, like any other part of your home, require regular maintenance to ensure their proper functioning and longevity. Periodically clean the windows, check for any signs of damage or wear, and address any issues promptly. Regular maintenance will keep your egress windows in optimal condition and extend their lifespan.

Energy Efficiency

Consider the energy efficiency of the egress windows you choose. Energy-efficient windows can help reduce heating and cooling costs, improve indoor comfort, and contribute to a more sustainable home. Look for windows with high-quality glass, low-emissivity coatings, and proper insulation to maximize energy efficiency.

Safety and Security

Egress windows are primarily intended for safety purposes, so it’s crucial to prioritize security features. Choose windows with robust locking mechanisms, shatter-resistant glass, and reinforced frames for enhanced security. Additionally, consider installing window well covers or grates to prevent unauthorized access.

Warranty and Insurance

Before finalizing your egress window installation, review the warranty provided by the manufacturer and the contractor. Ensure that you understand the coverage and any limitations or exclusions. Additionally, check with your insurance provider to determine if installing egress windows can potentially lower your insurance premiums.


Egress windows are a vital component of any basement or lower-level living space. They provide safety, natural light, ventilation, and increased property value. By understanding the cost factors, types of windows available, and important considerations, you can make informed decisions and ensure a successful egress window installation. Prioritize safety, consult with professionals, and adhere to local building codes to create a space that is both functional and aesthetically pleasing. With proper planning and execution, your egress windows will enhance your home and provide peace of mind for years to come.
