Our Research Process
To identify the best window brands of 2025, we used a multi-step evaluation process:
- Consumer insights: Surveyed 1,000 homeowners who purchased windows in the past two years
- Customer feedback: Analyzed more than 1,500 verified reviews
- Direct research: Requested quotes and product information from top national providers
- Expert input: Consulted with licensed contractors and industry professionals
- Secret shopping: Assessed service quality and pricing transparency firsthand
Our methodology prioritizes real-world performance, customer satisfaction, and long-term value.
How Much Do Windows Cost?
Replacement window costs typically range from $400–$900 per unit, with an average price of $554 per window based on our survey of 1,000 homeowners. Double-hung windows, chosen by 79% of our survey respondents, generally cost around $555 per unit. On average, homeowners purchase about four windows, bringing total project costs to an average of $8,803. Installation costs usually range from $50 to $200 per hour, depending on the complexity of the job.
What Factors Impact Cost?
The cost of new windows varies based on the window type, materials, and how complicated the installation is. Labor costs will also rise in 2025 due to a shortage of skilled tradespeople and higher construction expenses. As a result, homeowners should expect both higher installation fees and potentially longer project timelines.
In addition, the number of windows you’re replacing and any customizations you choose, such as specialty shapes, custom colors, or upgraded hardware, can raise the total price.
Additional factors that impact cost include the following:
- Frame material: Vinyl is usually the most affordable, while fiberglass and wood frames come at a premium thanks to their durability and classic look.
- Window style: Basic styles like sliding and single-hung windows tend to cost less than larger or more customized options like bay, bow, or specialty windows.
- Energy efficiency: Features like double or triple panes, low-emissivity (low-e) coatings, and gas fills can add to the upfront cost but can lead to savings on your energy bills over time.
- Installation method: A simple retrofit (replacing the window within the existing frame) is often less expensive than a full-frame replacement, which requires more labor and materials.
- Labor: Skilled labor can add a significant cost, especially if the installation is complicated or requires additional expertise.
- Brand and warranty: Higher-end brands often come with a bigger price tag, but they may offer better materials, craftsmanship, and longer warranties that can be worth the investment.
How Do I Choose the Right Windows for My Home?
When choosing windows for your home, it’s not just about the look—it’s about getting the right balance of durability, energy savings, and long-term value. Below, we’ll highlight some key factors to consider while shopping for your next window upgrade.
Warranty
When investing in new windows, a strong window warranty is just as important as the product itself, protecting you from manufacturing defects, premature wear, and costly repairs. Since window replacement is a significant investment, reviewing window warranty terms upfront can save you thousands in the long run.
Castle offers a true lifetime warranty, and customers report that the company reliably honors it. Other brands, like Renewal by Andersen, provide limited coverage: 20 years for its Fibrex material and glass and 10 years for non-glass components like the frame and sash. Always check the fine print, as window warranties may not cover custom features like special glazings or brass hardware finishes.
Reputation
A window company’s reputation reflects its long-term reliability and trustworthiness. Strong reputation indicators include longevity in the business, industry awards, and a solid track record of customer satisfaction. Look for accreditation from trusted organizations, such as the Better Business Bureau (BBB), and certifications like the National Fenestration Rating Council (NFRC) label or Energy Star rating. In our consumer interviews, 80% of respondents said they found their installer through word of mouth, often from family or a trusted contractor. This reinforces the value of a strong reputation in guiding homeowners toward reliable professionals.
Customer Experience
Customer service can make or break your window installation experience, so it’s worth seeing how each company handles support, responsiveness, and follow-through. While reputation draws homeowners in, it’s the service during and after installation that often shapes satisfaction. We reviewed dozens of customer testimonials and third-party ratings on sites like the BBB and Trustpilot, and we spoke directly with homeowners to get a full picture of how companies perform in real-world situations, especially when handling problems or honoring warranties.
Energy-Efficiency and Materials
Investing in energy-efficient windows can save you money on utility bills year after year and prevent furniture and carpet fading. Look for Energy Star-certified windows with a low U-factor, which measures their ability to insulate your home. Features like multiple panes, argon gas fills, and advanced weather stripping are key to enhancing insulation, reducing drafts, and maintaining a comfortable indoor temperature year-round. These energy-saving elements can also protect your furniture, carpets, and décor from fading due to UV exposure.
Materials are equally important when selecting windows. The frame material you choose affects your windows’ performance and longevity. By considering your climate, maintenance preferences, and budget, you can select materials that will provide the best value and performance for your home.
