How much does it cost to install an egress window?

The word egress can literally be defined as "to emerge" and "a path out" and this is the main function of egress windows in any home. These windows are installed in specific locations in a dwelling as a means to provide an emergency exit in case of a fire or any other accident. This type of windows must meet specific requirements and size to be termed as an egress window. Residential building codes should have at least one egress window and that window must be a primary consideration during construction and design.

Apart from providing you and your family an escape route in case of an emergency, egress windows add value to your home. These windows add more square footage to your home and this equates to greater value. When opened, egress windows allow additional light to pour in and also act as a high-quality basement ventilator, bringing in fresh air from outside. Depending on your property, you can also use these windows to boost the aesthetic value of your home.

The average cost of installing a prefabricated below ground egress window can range from $2,500 to $4,000.

Other factors, such as where the window is to be installed, also affect the cost. Initial installation may require grading, drainage system and evacuation for creating a safe space outside the window to make exit and entry easier. Some other factors which may bring up the cost include additional labor, engineering, and equipment.

Requirements for egress windows

While each county, state or municipal government may have different requirements for egress window place, the International Residential Code (IRC) has developed some board standards which should be used as guidance:

Minimum height: 24 inches.
Minimum width: 20 inches.
Maximum sill¹ height from floor: 44 inches.
Minimum clearing once opened: 5.7 square feet.

In addition, these windows must be operational from the inside and must not need a tool or key to open. You may add grates or bars around the window but they too should be easy to open and not require any keys or tools.

Location: below or above ground

Egress windows may be installed in basements or in bedrooms, typically in rooms used for sleeping purposes.

Below ground egress window installations require digging into the ground and cutting your way through concrete and brick walls. This means you will have to think about getting permits and permissions from city utilities. Hire a skilled contractor to do the job. It can cost between $1,500 - $2,500.

Installing egress windows above ground is a fairly simpler process. Installing an energy-efficient window will cost about the same as having any other window installed. It may cost around $500 to $1,000.

Types

When installing an egress window, there are several options you can choose from:

Types of Window	Features	Best Suited For
Casement Windows² ($650 to $1,820)	Crack outward or swing open.	Ideal for Basements
Horizontal Sliding Windows³ ($450 to $1,300)	Much larger and thus require an even bigger opening	Ideal for larger rooms, such as living areas or bedrooms
Double or Single Hung Windows⁴ ($150 to $1,000)	Fixed at the sash Difficult to open if there is debris in the way	Best suited for large living spaces or room applications
Prefabricated Egress Windows ($2,500)	Several brands offer prefabricated egress windows for added convenience	Suitable for all locations
Custom Egress Window ($6,500)	It may be necessary depending on the structure of the house	Suitable for all locations

Labor

Installing an egress window requires complicated handiwork, hence it is best you hire professional help. Installing the window includes the following tasks: Cutting a hole (this is only required in case of a fully submerged basement), installing the window, setting up the well and ensuring it meets the code in terms of grade, steps/ladder and drainage and cleaning up the interior, which includes trimming the egress window, including the drywall⁵ wrap, casing, trim, and insulation.

As mentioned above, installing an egress window in the basement is more complicated and thus adds to the cost. Above-grade window installation for bedrooms and living rooms typically costs between $500 to $1,000 including labor costs.

However, due to the complicated nature of installing egress windows in basements, the project can cost you between $2,500 to $4,000 including labor costs. An experienced contractor should be contacted for this job.

Enhancement and improvement costs

High-end energy-saving windows

High-end windows with energy-saving features often end up costing more than their single-paned counterparts, around 10% to 20% higher than other windows whereas installation costs about the same.

Egress well escape systems

Egress well escape systems are beneficial for added safety. They are an extension, typically with attached steps or ladders to result in an easy escape. Installation costs can vary depending on the project but can cost between $1,500 to $1,800.

Well cover

A well cover is a sheet of material designed to cover the well and basement window. It is installed to prevent accidents and prevent the buildup of snow, water, and debris. Purchasing or installing a well cover can cost an average between $300 to $800.

Additional considerations and costs

Egress window installation is certainly not a DIY job as you can potentially disturb the entire infrastructure of your home, including the pipes and drainage system.
A sliding basement door on sloping property can act as a substitute for egress windows as long as it abides by the building codes and provides homeowners an emergency exit.
You will need a permit prior to installing an egress window. While most permits cost around $150 however, it typically depends on the value of the product. Unlike installing other windows, installing egress windows require more planning. Installing an egress window requires permits from city utilities. If you have hired a contractor, he will get the permit for you.
The warranty may vary from lifetime to limited time depending on the warranty.
Digging the basement in order to make an egress can interfere with the utility lines. This is why you should hire a professional. You may also call 811 in case you are doing a DIY project to locate utility lines.
According to the International Building Code, sleeping rooms and basements must have one emergency escape (this can be in the form of a skylight, patio, and window) that leads directly to a yard, court, alley or public street. However, it must meet certain criteria.
