During our firsthand experience shadowing an installation crew in St. Louis, Missouri, we saw the level of professionalism and care each Renewal by Andersen window installer displayed as they removed and installed new windows. The installers double- and triple-checked their measurements to ensure the windows fit properly.

Overview
Champion Windows is a good choice for larger window replacement projects thanks to its bundled pricing, frequent discounts, and flexible payment options. Champion offers several budget-friendly options for window replacement, including vinyl windows and in-house financing with 0% down and interest-free loans. Unlike some other providers, Champion includes installation in its pricing, helping to eliminate surprise add-on fees.
During our secret-shopping process, we saw promotions like buy two windows, get two free on the company’s website. This is an appealing option if you’re tackling a full-home project and want to save on costs.
Our Experience
In our firsthand test using a ceramic heat lamp and infrared thermometer, Champion’s Comfort 365 glass maintained a stable temperature, whereas a standard window heated significantly. This test highlighted the glass’s climate-controlling properties, showing how it can help regulate indoor temperatures and improve overall energy efficiency in your home.
Along with testing its products, we also explored the buying process. We used Champion’s free quote tool and found it slightly slower than with other companies, but it offered helpful visuals and allowed us to select how many windows we needed. We appreciated how the company listed discounts for each service upfront. After entering our project details, the tool let us schedule a consultation with our local branch for the next steps.

The company makes it easy to match your home’s style with a wide range of window designs and color options. The company offers 10 window styles along with 13 interior and 20 exterior colors. It’s a solid pick if you’re planning a larger home upgrade, since it also installs entry and patio doors, storm doors, siding, shutters, and garage doors. With so many options in one place, you can give your entire exterior a fresh, coordinated look.
Our Experience
During our secret shopping, we found that Window World’s quote process is simple. You can fill out an online form, and a representative will contact you to schedule an appointment with a design consultant. The consultant reviews your window options and helps place the order. However, the company’s website offers limited details about its lifetime warranty, unlike other brands that provide full warranty information online.
We also found the company may not cover certain products, such as impact windows, under its standard warranty. This could cause concern for homeowners in storm-prone areas.
Product Details

Overview
With energy-saving features and expert installation through local showrooms, Pella Windows offers reliable, well-crafted replacement windows that perform and look great. Pella has earned a reputation for its high-quality products, including vinyl, fiberglass, and wood window options. The company puts its products through tough in-house testing to make sure they hold up in extreme weather and daily use. Its wood windows come pre-finished, meaning they’re factory-painted or stained before installation for added protection. Its fiberglass frames are built to resist warping, rotting, and corrosion over time.
Our Experience
We researched the Pella quote and installation process and found that the company offers multiple ordering options, including online, in showrooms, and at Lowe’s. You can choose between do-it-yourself (DIY) installation or scheduling a free 90-minute in-home consultation with a Pella expert, who can provide a no-obligation quote.
If you move forward, installation typically takes a few hours to two days depending on the project. Working with a Pella expert qualifies you for the Pella Care Guarantee, which covers product and labor issues for up to 10 years. However, certain styles, like custom or bay and bow windows, require an appointment to order.

- Provides a wide selection of replacement window styles, including specialty shapes and skylights, to suit custom design needs

- Uses independent dealers for sales and financing, which can lead to inconsistent pricing and terms across locations
Overview
Marvin Windows is a good choice if you’re interested in non-traditional replacement window styles and smart home integration. The company offers a range of specialty options, including skylights and custom-shaped windows, for more creative and flexible designs. It uses high-performance materials like wood, aluminum-clad wood, and its proprietary Ultrex fiberglass, which the company claims is eight times stronger than vinyl. According to Marvin, the company can tailor its windows to suit all major U.S. climate zones, from cold northern winters to hot southern summers. Plus, the company’s Connected Home line integrates with smart systems like Alexa, allowing you to control windows and doors remotely.
Our Experience
Though the Marvin website offers a detailed catalog of products, it doesn’t include interactive shopping features like pricing tools or online configuration options found on other sites. Instead, you get directed to search for local dealers to explore products and request quotes. If you’re looking for replacement windows specifically, the site redirects you to the separate Infinity from Marvin website, where you can request a free in-home consultation.
This extra step of navigating to a separate site for replacements could feel confusing for some homeowners, especially those expecting a more streamlined experience. It also means that much of the shopping process, such as product comparisons, pricing, and installation details, depends on local dealers, which may lead to variations in service and availability.
Product Details
- Material options: Aluminum, fiberglass, and wood
- Warranty: Limited transferable
- Energy-efficiency options: Yes

Overall, these windows combine long-term durability with improved insulation for homes in demanding environments.
Our Experience
During our secret shopping, we tested Milgard’s online experience and quote process. The company offers specialized guidance for project planning for replacement windows, including resources on color and style selection, budget setting, energy tax credits, architectural styles, and more. Milgard even provides an innovative Inspiration Center visualizer tool in which you can add windows to provided sample homes or upload photos of your own to see how different options look in your space.
Milgard lets you request a free in-home consultation or quote via an online form, phone, or using the company’s dealer locator. You begin by entering your project ZIP code to find certified dealers in your area.

Our Experience

Although you can’t place an order or get a quote directly online, the site allows you to search for local dealers or retailers and includes a state-by-state breakdown of distributors to make finding a supplier easier.
We also found that JELD-WEN doesn’t offer instant online quotes for homeowners. Instead, you’ll need to fill out the “Get Help for Your Project” form or use the dealer locator to share details like your project type, number of windows, and ZIP code. A local dealer or contractor will then follow up to provide a custom quote based on your needs and measurements.

With energy-efficient features such as double-glazed windows and low-e glass coatings, Loewen balances aesthetics with performance.
Our Experience
We found that the Loewen website doesn’t offer the interactive features found on some competitor sites, like allowing you to switch between material types or preview customized options. However, it does provide detailed product information along with swatches of available finishes and colors to help guide your selection.
The company also doesn’t offer instant online pricing or quoting tools. Instead, you’re directed to the “Find a Dealer” page, where you can locate a certified builder or dealer based on your ZIP code. After submitting your information, a local dealer will contact you to discuss your project, take measurements, and provide a personalized quote for Loewen’s premium wood window products. Because installation and quoting are handled entirely by independent dealers, the process is highly tailored to your needs, but you will need to wait for direct consultation and follow-up to receive pricing.

- Warranty: Limited transferable
- Energy-efficient options: Yes

How To Tell If You Need To Replace Your Windows
Knowing when it’s time for a window replacement can save you money on energy bills, improve indoor comfort, and enhance your home’s curb appeal. Here’s a list of signs you may need to install new, energy-efficient windows:
- Drafts and uneven temperatures: Feeling a cold breeze in winter or added heat in summer, even when your windows are closed, often means the seals are worn out.
- High energy bills: If your heating and cooling costs keep climbing, your windows may no longer effectively insulate your home.
- Fog or condensation between panes: This typically indicates a broken seal in double- or triple-pane glass, reducing energy efficiency.
- Visible wear and damage: Cracked frames, rotting wood, or broken glass signal it’s time for full window replacement.
- Windows are hard to open or close: Warped frames or damaged tracks make windows difficult to operate and can become a safety concern.
How Much Do Replacement 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 nationwide. Double-hung windows, chosen by 79% of our survey respondents, generally cost around $555 per unit. On average, homeowners in our survey purchased four windows, with total project costs of around $8,803. Installation costs usually range from $50–$200 per hour, depending on the complexity of the job.
Factors Affecting Replacement Window Costs
Some factors affect the price of replacement windows more than others. For example, the type of window and frame material will usually determine total costs more than the glass type you choose.
Labor costs may 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.
Below, we detail the main factors that influence replacement window costs.
Type of Window
The type of window you buy is the biggest factor affecting replacement costs. Larger windows with multiple panes and design features, like bow windows, usually cost more than smaller, simpler windows. When shopping for new windows, consider both the look you want and the functionality it provides, such as added light, ventilation, or curb appeal.
The table below shows the average prices our survey respondents reported paying for the type of windows they purchased.
| Window Type | Average Cost Per Window |
|---|---|
| Awning | $288 |
| Bay | $1,131 |
| Casement | $344 |
| Double-hung | $357 |
| Picture | $775 |
| Slider | $339 |
Frame Material
Vinyl frames are typically the most affordable option due to their low manufacturing and maintenance costs, while aluminum is also budget-friendly but offers less insulation. Fiberglass, wood, and composite frames tend to cost more because of their superior durability, energy efficiency, and aesthetic appeal.
Glass Type
All of the brands we feature in this review offer double-pane glass, which is more affordable and performs well in most climates. However, you may find triple-pane windows worth the added cost if you live in areas with extreme heat or cold for more insulation.
Installation Method
Full-frame installation, which involves removing the entire window and frame, typically costs more than insert installation, where the new window fits into the existing frame. In addition, complex window styles, like bow, bay, or picture windows, often require extra labor, customization, or structural support, which increases installation costs.
Warranty Options
We recommend choosing a company that offers both a window warranty and an installation warranty, as this combination delivers the best value and long-term protection for your investment. While products with comprehensive coverage may cost more upfront, they can save you hundreds or even thousands by protecting against defects in materials and workmanship. This helps guarantee your windows perform as promised for years without unexpected repair expenses.
Energy Efficiency
Energy-efficient windows can make your home more comfortable while lowering heating and cooling costs. Many top models feature double or triple-pane glass, low-e coatings, and argon gas fills, which may cost more upfront but provide long-term savings and protect against ultraviolet (UV) damage. Each brand featured in this guide has solid Energy Star ratings and is rated by the National Fenestration Rating Council (NFRC).
The Most Common Types of Windows
When choosing new windows, it’s important to understand the most popular styles, how each one functions, and where they’re typically used. Below is a quick overview of the most common window types, along with the average prices from our 2025 survey.
How To Choose the Right Replacement Windows
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 highlight some key factors to consider while shopping for your next window upgrade.
- Certifications: Look for windows with Energy Star and National Fenestration Rating Council (NFRC) certifications. These labels confirm that windows meet strict standards for quality and performance, providing key metrics such as the U-factor, which measures how well a window prevents heat loss.
- Reputation and reviews: Select installers with proven experience and consistently positive customer reviews. Read online customer reviews and look for patterns of clear communication, prompt problem resolution, and honoring warranties.
- Professional Standards: We recommend working with companies that clearly outline their installation process, hold necessary state licenses, and carry liability insurance to protect against accidents or property damage.
- Product selection and warranty coverage: Consider companies that offer the styles, frame materials, and customization options that fit your design and energy goals. Review the warranty to see what it covers, how long it lasts, and whether coverage applies to both materials and installation.
Questions To Ask Window Companies
When we interviewed homeowners about their window replacement experience, every respondent said their consultations were helpful, and 73% reported that appointments lasted between 60 and 120 minutes. To make the most of this time, it’s important to come prepared. Asking the right questions can help you choose a reliable installer and avoid surprises down the line.
- Do you offer free estimates and consultations?: Confirm whether the installer charges extra for the initial appointment.
- What brands do you carry, and do you offer energy-efficient options?: Look for features like low-e coatings, multiple panes, gas fills, and Energy Star ratings to help reduce heating and cooling bills.
- What is included in the quote, and do you handle permits and inspections?: Ask if the estimate includes old window removal, trim work, permits, and warranties. A detailed breakdown can help you avoid unexpected charges in the future.
- Are your installers certified or factory-trained?: Installers need proper training to ensure proper window installation and to maintain warranty protection.
- What warranties do you offer on both windows and installation?: A solid warranty should cover both the product and the labor. Ask what the company’s coverage includes and how long it lasts.
- How long will the window replacement project take?: Timelines vary depending on the number of windows, but understanding the duration can help you plan around potential disruptions.
- Can I see examples of past projects or speak with references?: Verified reviews and completed project photos give insight into the company’s workmanship and customer service. Show caution if the company won’t share references.
- How do you handle issues after installation or unexpected problems, such as structural damage?: Whether it’s air leaks, water intrusion, or unexpected damage during the job, you’ll want a clear process for how the company handles repairs and follow-up service.
FAQs About the Best Window Brands

Some product lines are tailored to specific climate zones to maximize energy savings. To find the best fit for your home, compare NFRC ratings like U-factor, to find the right fit for your home.
How do I choose the best replacement windows for my home?
To choose replacement windows, start by considering your budget, home style, and specific needs, such as energy efficiency, durability, or noise reduction. Look for reputable brands, compare warranties, and ensure the company you choose offers the windows you prefer. If you need help selecting windows for your home, talk with a company representative for specific guidance.
How often do you need to replace windows?
Windows generally need replacing every 15–30 years, depending on the materials, weather conditions, and overall maintenance. If you notice drafts, difficulty opening or closing the window, condensation between the panes, or higher energy bills, it’s a good sign you need replacements.
Which type of frame material should I choose for my replacement windows?
Each window frame material has pros and cons. Vinyl is affordable and low-maintenance, wood offers a classic aesthetic and natural insulation, and fiberglass provides exceptional durability and energy efficiency. Your choice depends on your priorities and budget.
What are the most efficient replacement windows?
Reputable brands such as Renewal by Andersen and Castle offer highly rated energy-efficient options designed to reduce heat loss and improve comfort. Energy-efficient replacement windows typically have double or triple glass panes, low-e coatings, and argon or krypton gas fills.
How much should you spend on replacement windows?
Most homeowners spend between $400 and $900 per window, with an average cost of $554 based on our 2025 survey of homeowners nationwide. Pricing depends on the brand, materials, and features. Spending more up-front on durable, energy-efficient models can pay off in energy savings and fewer repairs in the future.
How do I get a quote from a window brand?
To get a quote from a window brand, you can fill out an online form, schedule a free in-home consultation, or call customer service for an estimate. During the consultation, a representative will measure your windows and discuss options to provide an accurate quote. We recommend comparing quotes from at least three different companies to find the best pricing and installation options.
Which company is better, Pella or Andersen?
When comparing Pella versus Andersen, the best option ultimately depends on your specific needs and preferences. Pella is known for its wide range of energy-efficient options and custom designs, while Andersen excels in durable materials and high-performance testing. If you’re looking for a more budget-friendly option with reliable energy efficiency, Pella might work best. However, if long-term durability and premium quality are your priorities, Andersen may better fit your home.
