Window Well Installation Prices

Choosing a window well material has a big impact on your budget. For a long-lasting window well, opt for the highest quality product you can afford. The most common materials are plastic, steel, fiberglass, and concrete.

The cost of materials only starts at around $800 for plastic and metal wells while higher end wells, including custom concrete ones, cost up to $2,800.

Plus, you'll need to account for the cost of the window itself, which costs $100 to $700, depending on the type and size of window you choose.

Window Well Installation Costs

Excavating the window well accounts for the majority of the labor costs, with a price range of $1,500 to $3,000. If you're also having an egress window installed, add an additional $100 to $250 per window in labor costs.

Window Well Installation Cost Factors

There are factors that can influence the cost of a window well installation. You should consider these when planning for your project. Talk to an expert to determine what the best option is for your home.

Getting a Permit and Meeting Code Requirements

In most municipalities, you'll at least need a building permit to add a window well and an egress window. This type of permit generally costs $50 to $300, but your contractor will most likely take care of this for you as part of the project fee.

Depending on the extent of the work and the regulations in your local area, you may also need a land surveyor and/or a structural engineer at a cost of $500 each.

Installing an Egress Window

If you're installing a window well, it follows that you'll need to install an egress window, too. These two jobs are usually part of the same project, which reduces overall cost. The type of window you choose has a direct impact on the total project price. The cost of an egress basement window is between $100 and $750 each.

Single-Hung Windows

Single-hung egress windows are the most common and most affordable. These egress windows cost $100 to $400 per window. Single-hung windows open vertically and work well in most window wells, including narrow ones where singing windows are problematic.

Double-Hung Windows

Double-hung windows cost $250 to $500 per window. These windows open from top to bottom, making them an excellent choice for hot climates, as they're pretty efficient when it comes to letting fresh air into the basement, compared with windows that open bottom to top.

Horizontal or Sliding Windows

Horizontal windows cost $150 to $700 per window. Horizontal windows slide open from one side to the other.

Casement Windows

Casement windows cost between $200 and $500 each. Instead of swinging or sliding open, casement windows are operated by a hand crank that allows precise adjustment for airflow.

In-Swing Windows

In-swing windows cost $350 to $700 each. They open inwards and are a popular choice for small basement window openings and narrow wells.

Window Features

Adding double paned windows increases the price per window to $200 to $500 for single-hung windows while triple-paned single-hung windows cost $300 to $800 each.

If you want a low-E coating, expect to pay an extra 10% per window.

In cold or very hot climates, to make the windows more energy efficient, you'll also need to apply weather stripping, which costs $130 to $400 per window.

Adding Window Well Covers

In order to protect your egress windows from the elements, dirt, debris, or critters chewing on your basement window frames, window well covers are necessary. The average price for a window well cover installation is $705, and the project price ranges from $370 to $1,115. The price depends on the type, size, and material of your chosen well cover.

Adding a Window Well as Part of a Larger Project

If you're adding a window well and an egress window, you're most likely finishing your basement and turning it into a livable space. Finishing a basement costs $7 to $23 per square foot and you may save on the total project fee by rolling the cost of the window well and egress window into that project.

DIY vs. Hiring a Pro for Window Well Installation

For window well installation, which can involve changes to the foundation and structure of your home, it’s best to hire a professional handyperson to do it for you. Some regulations must be followed to make sure your window wells meet the code for egress and security. You can check with your local municipality for requirements, or your window well installer can do that for you.

FAQs

What size should a window well be?

A window well needs to be 8 inches deeper than the base of the window and 6 inches wider on either side.

Does a window well need a drain?

The best option for most window wells is to connect a drain to the home’s existing drainage system. Your window well needs to be graded sufficiently to allow for fluids to run off correctly. If you notice moisture and a build-up of liquid in your window well, it needs better drainage.

When should I add a window well and cover?

For the best price from window installers and contractors, the best time to do this type of home improvement is during the winter, when their services aren’t as in demand, particularly for window work.
