Here are some other variables that can contribute to egress window installation costs.
Number of Window Installations
You’ll save on labor if you install several egress windows at once. Although building codes only require one per bedroom, adding additional windows will increase the space’s fresh air and natural light. If your basement is divided into more than one bedroom, you’ll need one egress window per room.
Permits and Labor
Installing an egress window typically requires a building permit and an excavation permit for below-ground windows. These can cost $50–$200 depending on your location and the the work’s extent. A professional contractor will be able to get the proper permits for you. They typically charge $40–$100 per hour.
Prefab vs. Custom
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 you’re converting a previously unfinished room into a livable space, there may already be a window that doesn’t 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.
You’ll have to pay for window removal if you want to convert an existing window into an egress window. Window replacement costs about $180–$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 home’s address also influences the project’s 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.
Window Well Installation
Egress windows need to serve as emergency exits, so the area around the window must have enough space to allow a person to climb out. You’ll 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.
The excavation usually costs $50–$300. You’ll also need an egress window well kit, costing $1,600–$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.
