Average cost to replace a window well
A window well replacement costs $1,000 to $5,000 total to remove and install a new window well. The window well itself costs $400 to $2,800, depending on the material.

A window well, or egress window, is an excavation around a basement window that sits at or below ground level. It allows for more natural light, provides an emergency exit (egress) from the basement, and helps drain water from the foundation and basement windows when properly installed.
Window well cost by material
The cost of a window well varies based on the material, each offering different benefits in terms of durability and maintenance. Steel window wells are the most common and affordable, ranging from $400 to $800 before installation. Plastic or composite wells, costing $600 to $1,600, are also popular because they are lightweight and rust resistant.
Material | Average material cost* | Details |
---|---|---|
Steel | $400 – $800 |
|
Plastic / Composite | $600 – $1,600 |
|
Fiberglass | $1,000 – $2,000 |
|
Concrete | $1,500 – $2,800 |

Additional window well costs
When replacing a window well, you may want to consider making other improvements at the same time, such as replacing the windows themselves, adding a cover, or improving the basement drainage system. These services not only enhance the safety and functionality of your basement windows but also contribute to the overall maintenance and value of your home.
Window replacement
Many homeowners choose to replace the entire window when replacing the window well. This is especially common if the existing window is old, damaged, or inefficient. Egress window replacement costs $150 to $1,200 for the window alone and $200 to $500+ for labor to remove and replace the existing egress window with a new one, not including replacing the window well.
The following table details the most common basement egress window types:
Window type | Average price per window (unit only) | Description |
---|---|---|
Casement | $200 – $1,000 | Hinged on the side and opens outward, typically with a hand crank |
Double-hung | $250 – $800 | Slides up or down from both the top and bottom |
Single-hung | $150 – $500 | Slides up from the bottom |
Horizontal / sliding | $250 – $1,200 | Slides open to the left or right |
Along with the window type, the glass quality also impacts the cost:
Single-pane windows have only one layer of glass and cost $150 to $400.
Double-pane and triple-pane windows start at around $400 and have additional layers with air or argon gas sandwiched between the glass for better insulation and improved energy efficiency.
Upgrading to low-E-coated, frosted, or laminated glass increases window prices by 10% to 20%.
Window well covers
Installing a window well cover is another popular add-on service. Covers cost $250 to $500+ and help keep debris out of the well, prevent accidents, and potentially improve drainage. They also provide an additional layer of insulation and security. Options include custom-made covers, polycarbonate covers, and grates. Prices vary based on material and design.
Drainage & waterproofing
Proper drainage is crucial for window wells. This often involves installing a new drainage system or implementing waterproofing measures to prevent water infiltration. These services are essential for keeping basements dry and protecting the foundation from water damage.
Costs may include:
Weather stripping installation costs $5 to $10 per window.
Basement waterproofing costs $4,500 to $10,000 for interior waterproofing of a 750- to 1,000-square-foot basement.
A new basement drainage system costs $4,000 to $12,000 for an interior perimeter drain tile system, while a French drain costs $4,000 to $15,000.
Window well enlargement
You may opt to enlarge your window wells during replacement to increase the amount of natural light it lets into the room or meet egress requirements for a basement remodel that includes living space. Enlargement typically requires additional excavation costs of $500 to $1,000 but can significantly enhance the usability and safety of basement areas.
Foundation repair
While replacing a window well, any issues with the surrounding foundation should be addressed. Foundation repairs cost $2,000 to $12,000 on average to repair a foundation leak. Addressing these issues during well replacement can prevent more serious problems in the future.
Landscaping
After a window well replacement, some landscaping work may be necessary to restore the area around the window well. Landscaping costs $4 to $12 per square foot or $50 to $100 per hour for landscaping labor. Proper landscaping can help ensure good drainage away from the foundation and maintain the aesthetic appeal of your property.
Window well replacement cost factors
Several factors contribute to how much you’ll spend to replace a window well:
Size: Larger window wells cost more and take more labor to install, increasing costs.
Access: Difficult-to-access areas may increase labor costs.
Labor: Hiring a handyperson to replace a window costs less than hiring a general contractor to manage the project.
New vs. replacement window well: The cost to install a new window well is higher than to replace an existing one that has the excavation already done. However, enlarging the window well during a replacement can also incur additional excavation costs.
Adding new windows: It’s common to replace the egress window when replacing the window well, especially if there are leaks.
Adding a drainage system: Installing proper drainage can add to the overall cost but is crucial for preventing leaks and basement flooding.
Local regulations: Some areas may require additional features, permits, or inspections, potentially increasing costs.

Window well replacement FAQs
What is a window well?
A window well is a semi-circular or rectangular excavation around a basement window that sits at or below ground level. Its primary purpose is to allow more natural light into basement spaces and provide an emergency exit—also called egress—in case of fire.
Who replaces window wells?
For simple replacements, landscapers or experienced handypeople can install or replace window wells. More complex projects may require a general contractor or specialized window well service.
Why replace a window well?
Window wells may need to be replaced for several reasons:
Water infiltration, such as flooding, leaks, or moisture damage near your basement windows
Structural damage, including rust, rot, holes, or scrapes on metal wells, and warping or decay on wooden wells
Window wells that have loosened or detached from the foundation well due to factors like rust damage or freeze-thaw cycles
Insufficient space for emergency egress or proper window operation
Outdated materials like older metal or wooden window wells that are prone to deterioration
Need for more efficient drainage systems, such as perforated pipes or gravel-filled reservoirs, which can better manage water runoff
Safety concerns if your current window well lacks proper covers or safety grates
Is it difficult to replace a window well?
Replacing a window well can be challenging, especially for those without experience, and mistakes can lead to significant issues like water damage. While some homeowners may attempt it as a DIY project, professional installation is recommended for the best result.
Getting estimates from window companies
When seeking a local window well installer, follow these suggestions:
Request quotes from at least 3 different contractors using the same window well size and materials for comparison.
Choose companies with proper licensing, bonding, and insurance that have been operating for over 5 years.
Check customer feedback on platforms like HomeGuide and Google to assess work quality and reputation.
Ask for a written agreement and warranty before starting the project.
Avoid paying the entire amount before work begins. Reserve the last payment until the job is finished and all necessary inspections have been cleared.
