How Much Does Window Replacement Cost in Chicago? [2026 Data]

Chicago weather can be brutal, so having quality windows is essential. The average window replacement cost in Chicago, Illinois, is $5,943, with a typical range of $2,766 to $9,191. The exact cost will depend on the number of windows in your home, the frame and glass material, and your chosen window style, among other factors. Learn how much you can expect to pay for your Chicago window replacement project.

Window Replacement Cost Factors

Each window replacement project in Chicago differs depending on several factors. Learn about the most influential ones below.

Number of Windows

Home sizes in Chicago vary from under 1,000 square feet for a downtown condo to an average of 3,300 square feet for a new house in the suburbs. Smaller condos might have fewer than 10 windows, while larger single-family homes can have double or triple that number. The more windows you replace, the higher the cost. On average, expect to spend around $750 per window.

Frame Material

Chicago experiences a wide range of weather, from the heat and humidity of summer to the freezing temperatures and lake-effect snow of winter. Choosing the right window frame material can help insulate your Chicago home from the wide range of weather the city experiences throughout the year.

• Vinyl windows are typically the most affordable choice, offering high energy efficiency and low maintenance. 

• Wood windows are classic and long-lasting, but they require additional maintenance to protect them from moisture and insect damage.

• Fiberglass windows are strong, durable, and energy-efficient, but tend to cost more than vinyl or wood windows.

• Aluminum windows are lightweight and strong, but tend to cost more than other types of window frame materials.

Fiberglass windows last the longest—up to 50 years and beyond.

Window Style

The window style in a home typically depends on the home's design. Many Chicago homes have single- or double-hung windows that can be opened to let in the breeze on a spring or fall day. These types of windows are generally the cheapest to replace. If you opt for a more complex window design, such as bay or bow, expect your window replacement costs to be higher. Awning and casement windows are ideal for condos. Here are the average prices for different window styles.

Glass Type

The right type of glass can maintain a consistent temperature in your home, regardless of the weather outside. It’s best to avoid single-hung windows in Chicago since they aren’t good insulators. Instead, opt for double- or triple-pane windows, which will improve your home’s insulation and can also decrease noise infiltration from everyday city sounds. Low-emissivity (Low-E) glass is the most effective insulator, but it can prevent natural light from entering your home. Here’s what you can expect to pay for each.

Window Replacement Pro Costs

Window replacement isn’t a DIY-friendly job. Hiring a professional window replacement company in Chicago ensures that your windows are correctly installed. Here are the costs associated with hiring a pro for this project.

Labor

As a major metropolitan area, Chicago has a slightly higher cost of living than other, more rural areas. This can affect the price of labor, as contractors must charge more for projects to ensure they’re making a profit. Window installation is a highly labor-intensive project, so labor costs typically account for at least 15% of the total project cost. That means labor for an average $6,000 window replacement project will be around $900.

Permits

The City of Chicago requires you to obtain a permit for exterior window or door replacement. As long as you’re installing replacement windows in an existing opening, you can apply for a permit online through the city’s Express Permit Program. However, if you’re installing a window in a new opening, the permit application process can take a little longer. A pro will usually include the cost of the permit in their quote and will handle the paperwork themselves.

Taxes

The total sales tax rate in Chicago is 10.25%. That percentage includes the following:

• Illinois state tax: 6.25%

• Cook County tax: 1.75%

• City of Chicago tax: 1.25%

• RTA tax: 1%

If you’re completing your window replacement project through a pro, your quote will include tax. However, if you’re purchasing the windows yourself and either doing the installation yourself or hiring a professional for the installation, you’ll need to factor this tax rate into your budget.

Licensing and Certification Requirements

Cook County requires window contractors to be registered with the Cook County Department of Building and Zoning. A window replacement pro may also be required to hold a valid City of Chicago general contractor license. Before signing any work agreements, verify that your window contractor has the necessary licenses and certifications to perform the work legally.

Tipping

It’s not required or expected to tip your local window replacement pro, and many Chicago homeowners find that they don’t have the funds to offer a tip after budgeting for this pricey project. However, you might consider tipping if the contractor went above and beyond expectations. If you do plan to tip your window pro, don’t forget to include a 10% to 20% tip in your budget.

Does Window Replacement Increase Home Value?

According to data from the Journal of Light Construction, vinyl window replacement has a 73.6% return on investment (ROI) in Chicago, while wood window replacement has a 73% ROI. For a $8,000 window replacement project, you can expect to recoup around $5,840 from the job cost when it comes time to sell your home.

Window replacement can increase your home value in several ways. First, new windows can enhance your home’s curb appeal, making it more attractive to potential buyers. Second, replacing old, inefficient windows with new, efficient ones can help you maintain a consistent temperature in your home, which is a huge plus during hot Chicago summers or frigid winters. Finally, new windows tend to have fewer window problems and require less maintenance than old ones, which is a draw for buyers who want a move-in-ready home.
