What Is an Egress Window?
An egress window looks just like a regular window but opens fully to become a secondary emergency exit. You typically find egress windows in finished basements, where they add natural lighting and a striking exterior trim in addition to acting as a fire escape.
Egress windows come in multiple window styles, but simple casement and transom windows are the most common.

Egress Window Requirements
Many municipalitiesโ building codes actually require egress windows in livable spaces below the fourth floor. Codes require the window be a certain size so that an adult can exit safely and swiftly. The International Residential Code (IRC) sets the qualifications for an egress window to be considered part of an emergency escape route.
The area directly outside the egress window must also meet specific requirements, such as being installed below ground level (also called โbelow gradeโ) and including a window well. A window well is a U-shaped barrier made of ribbed metal or plastic. It prevents water from pooling around the window and allows more access to the emergency exit.
The IRC requires these measurements for egress windows:
- Minimum height: 24 inches
- Minimum width: 20 inches
- Minimum opening: 5.7 square feet above ground or 5 square feet below ground
- Maximum distance from the indoor floor to the window base: 44 inches

What Affects How Much a New Egress Window Costs?
How much an egress window costs depends primarily on the following factors:
- Glass quality: Windows that are double-paned or made of coated glass cost more.
- Location: Egress windows installed above ground cost less than those that must be partially or totally below ground
- Window type: Casement windows are the most popular, but other types are available that come at different price points.
Glass Quality
Like other quality replacement windows, egress windows come in single-, double-, and triple-pane options. More panes means more sound insulation and energy efficiency, though double-pane is the standard.
Multipane glass increases a windowโs resistance to shattering and cracking. It also adds noise reduction and helps with ventilation and heat exchange. Low-emissivity (low-e) glass adds even more energy efficiency, using a transparent glaze that blocks more ultraviolet (UV) rays than standard glass. Incorporating argon gas between the panes adds further insulation and reduces heat transfer, helping to preserve your homeโs internal temperature.
You can also opt for tempered glass, which is heat-treated for additional strength. Consider installing a top-rated storm window for added protection if you live in an area that experiences harsh weather.
Below is a list of different glass options and their average costs per window*:
Glass Type | Cost |
---|---|
Argon gas between panes |
$375โ$2,720 |
Double-pane glass |
$280โ$1,500 |
Low-e glass |
$280โ$1,500 |
Storm windows |
$90โ$400 |
Single-pane glass |
$100โ$350 |
Tempered glass |
150โ$3,000 |
Triple-pane glass |
$300โ$2,700 |
*Note that the prices listed in these sections are for individual aspects of the window. Additional materials and professional installation will increase your project cost, as will adding a window well if installing the window in a basement.
Location
Whether the window is installed above-ground or below-ground affects the total cost significantly. Windows that sit below ground require excavation and soil shoring to preserve drainage, increasing labor costs. While less common, skylight egress windows are more expensive because theyโre harder and more time-consuming to install.
Location | Price |
---|---|
Attic |
$900โ$3,000 |
Bedroom (above ground) |
$900โ$3,000 |
Living room (above ground) |
$900โ$3,000 |
Skylight |
$1,500โ$4,000 |
Basement (below ground) |
$2,500โ$5,300 |
Cost by Window Type
Casement Windows
Casement windows are the most common egress window type. Theyโre hinged on one side and open with a hand crank. The entire window swings outward like a door.
![Casement_Window casement window icon](https://dlczb9lfz9r73.cloudfront.net/wp-content/uploads/2024/01/23154258/Casement_Window-e1706042595729.png)
Double-Hung Windows
Double-hung windows have two sashes that can be moved up and down to open a portion of the window. Because only half of the window can be open at a time, double-hung egress windows must be a minimum of 4 feetโtwice the height of the code requirements for an emergency exit opening.
![Double_Hung_Window double hung window icon](https://dlczb9lfz9r73.cloudfront.net/wp-content/uploads/2024/01/23154606/Double_Hung_Window-e1706042782699.png)
In-Swing Windows
Casement windows that open inward are called in-swing windows. Theyโre popular for egress windows, but the interior space around them must remain clear so they can open
![in-swing-window](https://dlczb9lfz9r73.cloudfront.net/wp-content/uploads/2024/02/13135316/in-swing-window.png)
Single-Hung Windows
Single-hung windows are similar to double-hung windows, except only the lower sash moves. These are typically the least expensive windows, but they have the same problem as double-hung windows: They must be twice as tall as the legal requirement.
![Single_Hung_Window single hung window icon](https://dlczb9lfz9r73.cloudfront.net/wp-content/uploads/2024/01/23155155/Single_Hung_Window-e1706043130983.png)
Sliding Windows
Sliding windows open horizontally. Again, this means they must be twice as wide as the requirement of 20 inches to create an opening large enough to meet building codes.
![noun-sliding-doors-1074097-7B7A78](https://dlczb9lfz9r73.cloudfront.net/wp-content/uploads/2024/02/06143356/noun-sliding-doors-1074097-7B7A78.png)
Window Type | Price |
---|---|
Single-hung |
$100โ$400 |
Sliding |
$150โ$600 |
Double-hung |
$150โ$650 |
Casement |
$150โ$1,000 |
In-swing |
$350โ$700 |
What Are Additional Cost Factors in Egress Window Installation?
Youโll save on labor if you install several egress windows at once. Although local building codes only require one per bedroom, adding additional windows will increase the spaceโs fresh air and natural light. If your basement is divided into more than one basement bedroom, youโll need one egress window per room.
Installing an egress window typically requires a building permit and an excavation permit for below-ground windows. These can cost $50โ$200 depending on your location and the workโs extent. A professional contractor will be able to get the proper permits for you. They typically charge $40โ$100 per hour.
Egress windows are more functional than decorative, so most homeowners opt for prefabricated versions. These cost less and are easier and cheaper to install. You can customize your egress window for a higher cost if you feel creative or have an unusual space to fit the window. Keep the code requirements for an egress window opening in mind, though.
If youโre converting a previously unfinished room into a livable space, there may already be a window that doesnโt meet code requirements. You can often remove the old window, cut the hole larger, and install a new window in its place. Window replacement costs are higher if more labor is required. This project can cost as little as $200 if no resizing is needed to more than $1,000 to dig a larger well.
When you install an egress window, you have to pay for both the window materials and the corrugated metal or plastic that creates the window well. Some egress windows also include step ladders and further ventilation to improve safety and performance. The more materials required, the higher the cost.
Youโll need to pay for window removal if you want to convert an existing window into an egress window. Window replacement costs about $180โ$409 per window, but the type of window being removed and its accessibility can increase or decrease this price. We recommend reading our guide to window replacement costs to calculate potential window removal costs.
You can install egress windows anywhere in your home, but basement egress windows tend to cost more than other locations due to the addition of the window well.
Your homeโs address also influences the projectโs cost. For example, a window installer has to install the egress window at a different depth depending on your water table level. The deeper the window must go, the higher the cost. Additionally, prices will be higher in areas with higher costs of living. However, a window installer may charge about 50 cents per mile if they have to travel to a remote location.
Egress windows need to serve as emergency exits, so the area around the window must have enough space to allow an adult to climb out. Youโll need to excavate a window well for below-ground egress windows. This job may require a land surveyor and structural engineer to ensure your foundation remains secure and your yard has proper drainage. These professionals charge about $500 per visit.
Excavation usually costs $50โ$300. Youโll also need an egress window well kit, costing $1,600โ$3,000. This kit is typically made of fiberglass or metal. It has all the materials you need to install egress windows, including the window itself. You can also purchase the parts a la carte. High-end kits are often made to look like stone or brick.
Below are the prices for the various items needed for window well installation.
Window Well Installation Cost by Material
Material | Price |
---|---|
Stepladder |
$70โ$260 |
Grate |
$150โ$500 |
Well barrier |
$400โ$2,100 |
Window well cover |
$280โ$1,000 |
Entire kit |

DIY Egress Window Installation
Installing an above-ground egress window is tricky if you donโt have an understanding of masonry and framing. You need to first determine if the wall you plan to install on is load-bearing. If it is, it may be necessary to install a header above the window on the interior framing and a lintel to span the masonry exterior. The job can get complicated quickly if youโre not familiar with this type of work.
Here are the basic steps if you do choose to attempt the project on your own:
Double-check the window size and operation requirements, then measure and mark the space on the interior wall where the window will go.
Drill a pilot hole through the wall and measure and mark the exterior wall.
Build an interior support frame out from the wall studs and hang plastic sheeting for easy cleanup.
Cut around the inside perimeter with a concrete saw, first as a shallow groove to follow your measurements, then halfway through the wall.
Go to the exterior wall and complete the cuts there.
Knock out the concrete blocks, smooth the sides of the hole, and patch holes with concrete.
Install the wooden window frame and caulk to seal it.
Remove the support frame and lift the window into place, installing it according to manufacturer instructions.
