Think of being in an emergency where each second counts and there is no safe exit. This nightmare becomes a reality for many residents whose houses don’t have egress windows.

Understanding what they are is important, especially for those who plan on getting a window replacement. As a trusted home remodeling contractor with 26 years of experience, we’ve put together all the information to help you get familiar with the window egress systems and eventually choose extra safety. Moreover, this guide covers the key aspects, from types and sizes to benefits. After reading it, you can make informed decisions to protect your home and loved ones.

What Is an Egress Window?

As previously established, a window egress system serves as an emergency escape from a building in the event of a fire or other danger. Such a system is essential in homes, especially bedrooms, and basements, to provide rescuers with quick access and residents with a safe escape. Therefore, egress windows must meet specific standards and comply with building codes, such as the International Residential Code (IRC).

When Do You Need an Egress Window? 

First and foremost, you should establish a safe environment for you and your family. That’s when egress windows come into play. Without one, you won’t meet the safety requirements for your living space. No one is exempt from flooding, fires, hurricanes, and any other types of dangers. 

Whether you’re finishing your basement to create more living space or just updating an older home to meet today’s standards for safety, a proper emergency exit is a necessity. If you find yourself asking, “When do you need an egress window?”  the answer is “always,” because your family’s lives are the priority.

What Qualifies as an Egress Window?

In most states, egress window installation is required by law. Consequently, there are certain rules for their construction. Keep in mind that these rules may vary depending on your location, so be sure to satisfy the requirements specific to your state. The most important include: 

  • The egress window opening should be sufficiently large to enable a person to climb out during an emergency. 
  • There must be at least one basement egress window easily accessible without a key. 
  • Most building codes require that the minimum opening should be at least 5.7 square feet for upper floors.
  • The escape route must lead to the public area, not another building.
  • The height from the floor should not exceed 44 inches. 

Your window egress system should meet these standards to avoid fines or legal issues. A properly installed exit construction not only ensures safety but also complies with building regulations.

Types

There can be several types with advantages, depending on your home’s layout or style. Explore the most common ones, as well as their prices per unit.

Casement Windows

This egress window installation has a hinge on the side and opens outward. Because of this construction, the casement style has wide openings that easily meet emergency requirements. It’s popular for smaller openings due to their capability to maximize the space available for escape. How much does an egress window cost? For the casement option, the price ranges from $150 to $500. 

Double-Hung Windows

This is a type with two operable sashes that slide vertically. They can qualify as egress windows, but they need to be large enough so that the opening meets the minimum requirements when fully open. On average, you will pay between $150 and $650. 

Sliding Windows

Sliding egress window installation opens by sliding horizontally on a track. This style is attractive because it doesn’t require a lot of space, which is perfect for attic areas. Plus, sliding replacement windows are easy to open. The cost varies between $150 and $750. 

Basement Egress Window Options

Typically, a window well is required for this type of installation, which takes place below grade. These window egress systems must meet the minimum size and accessibility requirements for a safe exit in emergencies. The price for this option ranges from $100 to $700, but a window well will add up from $500 to $1000 more.

Sizes of Egress Windows

What qualifies as egress windows may vary depending on the room where it is placed. Generally speaking, what is the minimum egress window size? It must be 20 inches wide and 24 inches high. However, such dimensions will not provide the required 5.7-square-foot opening unless the unit is larger. 

Alternatively, you may ask how to calculate egress window size.? To calculate if your window meets the requirements, multiply the width and height of the openable portion of the unit. Ensure it matches the minimum openable area required by local building codes.

Benefits of Egress Window Replacements

Egress window installation brings multiple benefits beyond mere compliance with building codes. Some of the key advantages include:

Improved Safety

Such window systems primarily serve as a safe exit from a house during an emergency, as has been already mentioned. In the event of a fire or other life-threatening situation, they provide an accessible escape route for you and your family.

Boosted Airflow

Egress windows greatly improve airflow within rooms, including basements. This increased ventilation helps reduce dampness and prevent mold growth on the walls.

More Daylight

These windows can significantly brighten up the space and improve your home’s overall atmosphere. They allow more daylight into basement areas that might otherwise be dark, dingy, and uninviting.

Summary

Egress windows serve as both a crucial safety feature during emergencies and a means of meeting building code requirements. Understanding the different types, sizes, and requirements will help you choose the right replacement windows for your home. The average price for sliding, casement, double-hung, and basement window emergency systems ranges from $100 to $700. Also, installing a window well may cost an additional $500 to $1000.
