A Comprehensive Guide to Attic Egress Windows and Installation

Attic egress windows are a game-changer for homeowners who want to add natural light and ventilation to their attic spaces. They provide a safe and accessible way to enter and exit the attic, which is a requirement in many jurisdictions.

An attic egress window is typically installed in the gable end of a roof, replacing a traditional window. According to the International Residential Code (IRC), an attic egress window must have a minimum net area of 5.7 square feet and be at least 5.7 square feet in size.

The installation process for attic egress windows can be complex and requires careful planning. It's essential to hire a professional contractor who has experience with attic egress window installations.

The cost of installing an attic egress window can vary depending on the size and type of window, as well as the complexity of the installation. On average, homeowners can expect to pay between $3,000 to $10,000 for a standard installation.

An attic egress window must meet specific requirements to ensure safe and easy escape in case of an emergency. The International Building Code states that the window must open directly into a public street, alley, yard, or court.

The net clear opening of an attic egress window must be at least 5.7 sq. ft. This is the actual free and clear space that exists when the window is open, not the rough opening size or glass panel size. Code officials want the opening large enough so firefighters can comfortably crawl through the window in full protective gear.

The opening height must be at least 24 in., and the opening width must be at least 20 in. The bottom of the clear opening must be within 44 in. of the floor. Bars, grilles, and grates over windows must be operational without tools or keys and still allow the minimum clear opening.

Here are the key requirements for attic egress windows:

These requirements ensure that an attic egress window provides a safe and easy means of escape in case of an emergency.

An egress window in your attic is a must-have for safety reasons, and it's not just about installing any old window. The International Residential Code requires an emergency escape and rescue opening in habitable attics, which must open directly to a public way or a yard or court that opens to a public way.

The minimum width of an egress window is 20 inches, and the minimum height is 24 inches. This might not seem like a lot, but it's crucial for emergency responders to have enough space to enter and exit your attic safely.

These dimensions are in place to ensure that emergency escape and rescue openings are large enough for firefighters and paramedics to access in an emergency. The opening must also be operational from the inside without keys or tools.

Custom dimensions and sizes for windows can be a bit tricky, but understanding the basics can help you make informed decisions.

Typically, custom windows are designed to fit specific openings or spaces, which can vary greatly depending on the type of window and its intended use.

For example, a custom sliding glass door might be 6 feet wide and 10 feet tall, while a custom casement window might be 4 feet wide and 5 feet tall.

Some custom windows, like bay windows, can be quite large, spanning up to 12 feet wide and 8 feet tall, while others, like skylights, are much smaller, only 2 feet wide and 4 feet tall.

The size and shape of a custom window can greatly impact its functionality and aesthetic appeal, so it's essential to consider these factors when designing or installing a custom window.

In addition to the size, the shape of a custom window can also vary, with some featuring a more traditional rectangular shape, while others, like circular or arched windows, can add a unique touch to a room.

Installation costs for an attic egress window can vary significantly depending on the level of expertise and the extent of the installation.

A highly skilled homeowner may be able to install an attic egress window and well themselves, but some tasks may require a professional contractor.

Hiring a professional to perform the installation can cost between $1,500 and $3,000, as they will handle excavation, foundation cut, and window and well installation.

For a DIY approach, a handy homeowner can install a complete kit for around $1,495, but they may need to outsource the foundation cut and installation of the window and well, which can add up to around $2,750.

The largest labor expense is usually excavation, which is why some companies have created patented window wells that minimize the required excavation space.

Material costs can be a significant portion of installation costs, especially for large or complex projects.

The cost of materials can vary greatly depending on the type and quality of the materials used. For example, high-end finishes like hardwood flooring can cost upwards of $15 per square foot.

A good rule of thumb is to allocate at least 30% of the total installation cost to materials.

The cost of labor, not materials, is usually the largest portion of installation costs, with some projects having labor costs as high as 70% of the total cost.

Labor costs can vary depending on the complexity of the installation. A highly skilled homeowner might be able to install an egress window and well themselves, but tasks like excavation and cutting an opening for the window through the home's foundation are best left to a professional contractor.

Hiring a professional to perform these tasks, along with the window and well installation, usually costs between $1,500 and $3,000. This is a significant investment, but it ensures the job is done correctly and safely.

Installing a below-grade egress window requires excavation to remove enough dirt to accommodate the large window well. This can be a labor-intensive task, and the largest labor expense is usually excavation.

If you're a handy homeowner, you might be able to save some money by performing the excavation yourself, but you'll still need to hire a professional for the foundation cut and installation of the window and well. In this case, the cost is around $2,750.

Some companies, like Bright Ideas Egress, offer complete kits that can be installed by a handy homeowner for $1,495. This is a more affordable option, but it still requires some DIY expertise.
