Our Take on Champion Windows

Champion Windows offers replacement windows, doors, screen doors, sunrooms, and vinyl siding. Champion is best known for its vinyl windows—most of its currently available windows have a vinyl frame. Champion provides windows in more than 30 states and has been in business for more than seventy years. 

What sets Champion Windows apart from competitors is that, unlike other window manufacturers that outsource installation, Champion handles all phases of your window replacement project, from design through installation. This means you’ll get consistent service throughout your entire project—no surprises or communication gaps from different contractors. While some window companies use third-party manufacturers (that are often based overseas), Champion makes all of its windows in the United States.

Types of Windows Champion Offers

Champion Windows offers several styles of windows, as well as enclosures and doors. Here’s a list of common window types, enclosures, and doors offered by Champion Windows:

You can view a complete list of products on Champion’s website or by visiting a showroom near you. We visited a showroom in Durham, North Carolina, and saw most of these window types in person.

Cost of Champion Windows 

Of the 1,000 homeowners we surveyed in November 2025, 39 chose Champion Windows for their replacement window project. Those homeowners paid an average of $474 per window, about $50 less than the overall average of $527 for vinyl windows. 

While installing new windows is not a cheap project, the cost of window replacement mostly depends on the material, style, size, and number of windows needed for your home. For this reason, Champion doesn’t provide online pricing, but you can schedule an appointment to get a free in-home estimate before committing to a project.

To give you a better idea of Champion’s pricing, we listed average costs for different window replacement projects based on the number of windows purchased.

Champion Warranty and Customer Service

Since new windows are a large expense, we recommend looking at the warranty details of the window brand to see if it covers common damages, such as broken glass or deteriorating window frames. Champion offers a limited lifetime warranty on its windows, which covers the frame, sash, glass seal, and moving parts. What makes Champion’s warranty stand out is that it includes both parts and labor, so you won’t face unexpected costs for repairs. The warranty covers accidental glass breakage, which some competitors don’t include. 

It’s worth noting, per the company website, that the warranty “applies to qualifying products as long as the original purchaser owns the home.” This suggests coverage may not extend to subsequent owners.  

As for customer service, Champion provides full-service that begins with your initial consultation. A sales representative will visit your home, take measurements, and walk you through window options. Once you’ve made your choice, Champion’s in-house team handles everything—from manufacturing your custom windows to scheduling and completing the installation. After installation, you can reach Champion through its customer service hotline. Champion will send a technician to assess any issues before quoting repairs or replacement. 

Comparing Champion to Other Window Brands

We evaluated Champion compared to 14 other window replacement brands to recommend the best window replacement companies. Here’s how Champion compares to other brands on key points: 

How We Tested Champion Windows

According to our November 2025 consumer survey, 20% of homeowners replace windows to improve energy efficiency or reduce energy costs. So, we decided to test how a Champion Window held its temperature in extreme conditions. 

Our editors were intrigued by Champion’s Comfort 365^® Glass, which the company says blocks 93% of harmful UV rays from the sun. Champion designed this technology to keep heat inside during the winter and prevent heat from seeping into your home during the summer.

We wanted to see for ourselves if Comfort 365^® glass made a difference, so we designed a simple test at our editorial offices in North Carolina. The Champion Windows branch in Durham was kind enough to let us borrow a sample window for the day.

Keep in mind: While this test helped illustrate how windows handle climate control, there are several other factors that contribute to how windows help a home maintain its temperature (e.g., material, seal, sun exposure). We recommend scheduling an in-home consultation with a window company to choose the best replacement windows for your home.

Tools We Used

• A double-hung window with Comfort 365^® glass, provided by Champion Windows 
• Infrared thermometer gun
• Ceramic heat lamp with a 100W heat spot

The Testing Process

We started by reading the temperature of both a Champion window and an interior window at our editorial office in Raleigh, North Carolina. Both window temperatures measured approximately 70 degrees Fahrenheit, according to our infrared thermometer gun.

Next, we plugged in a ceramic heat lamp with a 100W heat spot and let it warm up for five minutes. We used the same infrared thermometer gun to read the heat lamp’s temperature. The temperature rose to more than 300 degrees Fahrenheit in just five minutes.

Finally, we placed the ceramic heat lamp behind the Champion window. We waited five minutes, allowing the window time to absorb the heat before reading the temperature. We repeated the same process on an interior window in our office.

What We Learned

After five minutes in front of the heat lamp, the Champion window temperature stayed near 70 degrees Fahrenheit, while the office window heated to more than 100 degrees Fahrenheit. In other words, the Champion Window maintained a stable temperature compared to the office window. This test helped demonstrate the climate-controlling properties of Champion Windows that could lead to better energy efficiency in your home.

What Customers Say About Champion Windows

When shopping for replacement windows, it’s helpful to get recommendations from friends or family or read online reviews. Past customers can offer key insights that our hands-on testing can’t—what it’s really like to live in a home with Champion windows for all four seasons. 

At the time of publication, the BBB was updating the business profile of Champion Windows, so we were unable to pull customer reviews from the site. We analyzed reviews submitted in the past three years for Champion Windows on its Trustpilot listings. Although the provider has a 3.8 out of 5-star rating, we didn’t find many recent positive reviews for the company on Trustpilot.

Keep in mind that it’s more likely for customers who have had a negative experience to submit a review to third-party review sites like Trustpilot and the Better Business Bureau (BBB). We recommend reviewing online reviews from multiple sources when researching window replacement companies.

Here is a sample of positive reviews for Champion Windows:

“Our sales rep was extremely helpful and professional. [He] answered all our questions. [We] were really impressed with the young man.” —Steve S. via Trustpilot, November 2025

“We hired Champion to convert our screen porch to a three-season room. The conversion now gives us the ability to use the porch for so many more occasions and for most of the year. The work was expertly done, and the quality is superb. So happy with the results!” —Lloyd H. via Trustpilot, December 2024

Here is a sample of negative reviews for Champion Windows:

“I rescheduled my consultation appointment; they were supposed to show up on 11/05 at 6 pm. Nobody showed up, called, or texted. I texted them, no response. Texted again, no response. If I can’t even get a professional rep to come out, I have to assume that’s reflective of company culture: high-pressure sales, not customer-centric.” — Lisa H. via Trustpilot, November 2025

“It’s been four months now on a warranty claim to replace a window sash that failed. Warranties are great if the company offering them backs them up in a timely manner. I’ve chased and chased Champion, and to date, I still have no idea if the window sash has been produced or where it is.” —Matthew C. via Trustpilot, September 2025

Are Champion Windows Right for You?

After testing, we feel more confident recommending Champion Windows to homeowners looking for energy-efficient windows to help control the temperature in their homes. Specifically, we feel comfortable recommending Champion to homeowners in warm climates, since those are the conditions in which we tested. We also like that Champion windows are manufactured in the U.S. and that the company provides full service from design through installation. It’s worth evaluating Champion when choosing your replacement windows.
