How Much Does It Cost to Add a Window to Your Home?

Homeowners often consider adding windows to improve their living spaces, and for good reason.

A well-placed window brings in natural light, opens up views, and can make any room feel larger and more inviting. Beyond aesthetics, it’s also a functional improvement, offering better ventilation. However, many homeowners are concerned about the cost to add a window to an existing wall.

How much you’ll actually pay to add a window depends on the size and type of window you install, the contractor you choose, and the difficulty of the job. But if you are making plans to sell your property, adding natural light to a dim room may add scale-tipping appeal to your home.

To give you the most current costs and value adds, we spoke with top real estate agent Sandi Van Camp, who works with 82% more single-family homes than her peers in Canandaigua, New York, and consulted with the Pella Corporation, which has manufactured window products since 1925.

Window addition cost overview

While window replacements typically cost between $300 and $1,650, new construction windows are more expensive due to the need for framing, siding, finishing work, and potentially rerouting plumbing or electrical lines. Installing a completely new window can cost as much as $5,000 per window.

The average labor cost for the project ranges from $100 to $400 per window, or approximately 15% of the total project cost. The type, size, and material of the actual window likewise influence the total cost of the project.

Real-life cost to add a window

Because there are so few online resources that list the current cost to add a window to an existing wall, we spoke with Pella Public Relations and Brand Communications Manager Nicolle Picray.

According to Picray, you can get a window estimate on the Pella website. However, she warns that homeowners should exercise caution when budgeting a window remodel based only on their online costs. Pella’s window estimator is really a tool designed for installers more than homeowners.

All Pella windows are custom-made, and prices are difficult to estimate without details about your location and project. Instead, homeowners should contact a local Pella rep for accurate pricing and recommendations.

As mentioned, you need to cover labor costs, as well as expenses for rerouting any wiring and for the materials needed to repair and finish the wall around the window. We break down these costs below.
