Replacing your windows is a big investment, whether you’re just installing one or upgrading your entire house. Most homeowners aren’t buying windows on a regular basis and may not know which features to look for or how to find a quality window worth the price.
We extensively researched the best replacement window companies to help you narrow down your choices. We put 15 popular window brands to the test by scoring them on the six factors we think are most important when shopping for windows: value, performance, selection, services, customer support, and reputation. We studied warranty policies, read more than 1,500 customer reviews, compared each brand’s product selection, and assessed energy performance.
Our team also surveyed 1,500 homeowners who bought windows in the last two years and spoke with two of our team members who purchased windows in the last three years to understand what customers are looking for and what the window-buying process is like. In addition, we consulted two industry experts on important window features to look for and joined a company’s installation crew on the job to understand the replacement window process.
The following five companies scored highest against our rating criteria. Our guide tells you why we recommend each one and which may work best for you.

Learn How Replacement Windows Are Installed
We strongly recommend using a professional for your replacement window project for reasons we explain in our guide. However, if you decide to tackle the job yourself, it is a good idea to familiarize yourself with the installation process. In the video below, This Old House’s Tom Silva gives a step-by-step walkthrough showing how to install replacement windows in your home.
Why Trust Our Replacement Window Reviews
When we surveyed 1,500 recent window buyers in 2024, the top two reasons people were looking for replacement windows were broken glass and air leaks—two things that impact your home’s energy efficiency and security. Both issues mean you likely want to pick a quality company and get the project started quickly. We strive to make this process easier by equipping you with the information and recommendations you need to make a decision fast.
We carefully researched 15 of the top replacement window brands in the industry to narrow down your best options. We used our survey to ask homeowners about their experience buying windows, which company they chose and why, how much they paid, which features made a difference in their energy savings, and more. Our team also spoke with two industry experts about what happens during the window consultation and ordering process, plus what buyers should look for when deciding between windows. Finally, we joined a professional installation crew at a job site to understand what to expect during window installation.
How We Selected the Top Replacement Windows
From our research outlined above, we developed six rating criteria to evaluate companies: value, performance, reputation, product selection, services, and customer support. We detail what we considered when weighing each of these categories in the sections below.
The following chart compares our top five companies’ overall scores to their price:
Value
To assess value, we first used our survey data to look at how much customers paid on average per window for our rated companies. We know from this data that the average price consumers paid per window was $1,500–$2,000. We considered a well-priced window to be one that cost $1,400 or lower. All of the companies in our top five met this criteria.
Window World was the most affordable brand of windows, averaging below $1,000 per window. Interestingly, the four brands we reviewed that averaged over $1,400 per window received the worst overall scores: Harvey, Jeld-Wen, Simonton, and Loewen.
We also looked at financing offers when scoring this category, since this impacts your total investment and helps you cater better to your specific budget. For example, some window manufacturers offer in-house financing programs and perks, such as generous discounts, no payments for 12 months, and loans with 0% interest rates that allow you to pay over time and require no money down.
We combined points for pricing and financing offers and ultimately scored Champion, Renewal by Andersen, and Window World highest in this category. All offer multiple financing incentives and valuable discounts, such as a buy-two, get-two-free deal.
Performance
We considered Energy Star certification and a lifetime warranty as the highest standard in this category. We gave the lowest points to companies that only provide limited warranty coverage. While every brand we reviewed was Energy Star-certified, not having this certification would have resulted in a major point reduction.
Roughly 28% of our surveyed window buyers said energy efficiency was the top reason they chose their selected window brand. The Efficient Windows Collaborative, one of the window industry’s most respected independent organizations, reported that replacing inefficient windows with energy-efficient ones lowers heating costs by at least 15% and cooling costs by 11%–37%. Energy-efficient windows reduce your energy bills, make your home more comfortable in every season, and potentially increase your home’s value.
A clear way to know if a window is energy-efficient is to look at its certification labels. The main label to look for is Energy Star certification. This label means that the window has been through rigorous independent testing to see how it performs in various climates. Windows won’t get Energy Star certification unless they use leading technologies such as low-emissivity (low-e) glass coatings and argon gas filling between panes—features that increase insulation. The label also tells you that the window is double-pane or triple-pane, as more panes mean better energy performance. Nearly 80% of our survey takers chose double- or triple-pane windows.
We don’t recommend buying a window without an Energy Star label. A sticker from the National Fenestration Rating Council (NFRC) indicates further independent energy testing and provides an even more detailed breakdown of performance. All brands we reviewed sell Energy Star-certified windows. Renewal by Andersen has won Energy Star Partner of the Year 10 years in a row.
Next, we evaluated warranty coverage. There are three primary types of window warranties:
- Lifetime warranty: All aspects of the window (parts, materials, screens, glass, installation, repairs, etc.) are covered for the window’s lifetime.
- Limited lifetime warranty: Some aspects of the window are covered for the window’s lifetime.
- Limited: Window aspects are covered at varying lengths of time.
We recommend a full lifetime warranty for maximum coverage. Champion and Window World both offer lifetime warranties, meaning they’ll fix your window if it breaks at any point. Most companies on our list offer a limited lifetime warranty, which varies according to the brand’s policy terms. Renewal by Andersen was the only company that made our top five despite having a limited warranty.
Here’s a look at our overall ratings for this category:
Reputation
We primarily looked at the Better Business Bureau (BBB) to score reputation but also evaluated customer reviews and scores on Trustpilot. In cases where a brand had fewer than 100 reviews across these sites, we looked at other forums such as Google Reviews, Facebook, and Reddit.
While BBB accreditation and scoring does matter to us, we look at it through a critical lens. A company’s BBB profile tells us whether it has any active lawsuits or patterns of unethical business practices, which we take seriously. But we also know that BBB ratings require meeting BBB criteria, which includes annual payments, advertising restrictions, and other factors we don’t think are important when judging a business’s reputation. When a company has a low or no BBB score, we use the customer rating and other site reviews as the source of truth.
We read at least 100 customer reviews per company and noted positive and negative themes. Because people typically leave reviews to express negative feedback, we investigated why customers held certain beliefs about a company. For example, we noted when customers complained about their warranty claim being denied when the issue clearly went against the company’s terms. We also dismissed reviewers who simply wrote that the company was a scam—a popular term on review sites—because every company we scored is a legally legitimate company.
We awarded the most points to brands with an A+ BBB score and average customer ratings of 3.6 out of 5 stars or higher. Brands with B scores and customer ratings of 2.1–3.5 were scored midtier, and we gave the fewest points to brands with scores below a B and ratings 2 out of 5 stars and below. Universal Windows Direct, Power Home Remodeling, and Harvey all did best in this category.
Selection
We looked at both inventory and quality to score this section. First, we checked how many window types companies offered, since this gives customers more customization options. The brands that made our top five all had at least seven styles.
We then evaluated frame material, checking how many materials each brand offered and the materials’ quality. Window frames are made using either aluminum, vinyl, wood, fiberglass, or a composite blend. While vinyl windows are the most common material type, vinyl and aluminum are the least energy-efficient and durable choices, so we gave these minimal points. We considered wood midtier because it’s more expensive than aluminum and vinyl, but it’s also more efficient and adds curb appeal. Composite and fiberglass windows are the most expensive but provide the best return on investment, so we scored them highest. They’re long-lasting, heavy-duty, low-maintenance, and supremely energy-efficient.
Most brands we scored only sell vinyl windows, but a handful sell other materials. For example, Window Nation sells vinyl and wood windows. Of the top five companies on our list, Renewal by Andersen offers the highest-quality material. Its proprietary composite blend, called Fibrex, is guaranteed to not rot, warp, or decay.
Lastly for this category, we gave points to window companies that sell doors in addition to windows, as it’s convenient for homeowners who want to upgrade both at once. You may also be able to get a discount by bundling. All brands that made our top five sell doors and windows.
Services
Some window companies have their own installation teams trained to install their products. We rated these brands higher for several reasons. For one, they don’t require you to find your own contractor. Secondly, this means your warranty coverage comes from one company, which should prevent an outside contractor from voiding the manufacturer’s terms or vice versa. Finally, in-house installers are specifically skilled at putting in the windows, and the scheduling and project management processes should be more cohesive. Nearly half (48%) of our 1,500 survey respondents chose a company that both makes and installs its windows. All the brands that made our top five have in-house installers.
We also awarded points to companies that offer additional services such as siding, roofing, and sunrooms. This is convenient because if you have multiple jobs to tackle, the company can schedule and complete them all at once, and you may get discounts for combining work.
Renewal by Andersen is the only company in our top five that doesn’t offer additional services. Window World stood out for being the only company we reviewed that installs shutters.
Customer Support
We assessed the following criteria to evaluate each company’s level of customer support:
- 24/7 support hours
- Daily support hours
- Online chat availability
- Online service form
- Online education guides
We gave the highest points to companies that provide customer support every day of the week—and extra if its team is available around the clock. We feel this accessibility is important because you can’t predict when a lawn mower might spit a rock through your window. In these instances, you don’t want to wait until Monday to schedule a repair. Castle is the only company we rated that provides 24/7 support. Every other brand limits its customer support to five or six days a week during traditional business hours.
We gave additional points to companies that offer various ways to reach them, such as an online chat feature or service form. Submitting an online service form may immediately put you on the list to get a repair and prevent you from having to make a call. However, we can’t guarantee how quickly companies look at these requests as they come in. An online chat feature also prevents you from having to use the phone when you just want to ask a quick question. We tested this with Castle, Window Nation, and Universal Windows Direct. Castle and Window Nation responded right away.
Lastly, we gave minor points to brands with educational resources on their website, such as maintenance guides detailing how to care for your windows or what to do in certain situations. We like these resources because they help customers and provide convenience.
Overall, Castle was the only brand that excelled in this category, offering 24/7 support, an online chat feature, and an online service form.
Our Top Replacement Window Brand Picks
After comparing 15 brands and surveying 1,500 customers, we believe the following five companies offer the best replacement windows in the industry. Each of our reviews details what we think is most important to know about the brand, such as its standout features and reasons why it may not be right for you.
You’ll notice that two factors we consider important in the table above aren’t discussed much in our reviews: energy efficiency and cost. That’s because the companies on our list fare pretty similarly in these categories. All sell Energy Star-certified windows, meaning their windows have been independently tested and confirmed to be highly insulative. Four of the brands are also in the same price bracket, with Window World being the only standout for its below-average prices.
Renewal by Andersen
Best Installation Pros and Cons
What We Liked
- Uses highly durable composite framing on all windows
- Provides in-house installation, so you won’t have to hire a contractor
- Brings a BTU meter to consultations to demonstrate energy performance
What We Didn't Like
- Has a limited warranty, whereas other brands have lifetime coverage
- May have installation delays
Our Review
Renewal by Andersen earned 4.8 out of 5 stars. The brand’s standout feature is its energy-efficient Fibrex material no other company has.
Renewal by Andersen is our top pick for a few reasons. We like its proprietary Fibrex framing, a composite material that’s more durable, weather-resistant, and energy-efficient than aluminum, vinyl, and wood but not quite as pricey as fiberglass. Renewal by Andersen is the only company that offers this. Most competitors only sell vinyl windows or a combination of vinyl and one or two other materials.
Fibrex is low-maintenance and much more insulative than other materials. That means it will keep warm air out of your home in summer and inside during winter. Plus, it won’t warp or crack like wood and vinyl if exposed to hot sun.
We also like Renewal’s in-house installation team. While the other brands on our list have in-house installation, Renewal is the only one with Certified Master installers who are highly trained both in their field and in installing Renewal products specifically. You get expert professional service, including job site cleanup and old window disposal after installation is complete.
If this all sounds great but you don’t think Renewal by Andersen is in your budget, you may be surprised. Despite its reputation for being expensive, our survey of window buyers showed the company’s average price per window is $1,194, putting it on par with most of the best-rated companies on our list.
The one thing we don’t love is Renewal by Andersen’s limited warranty. A limited warranty puts caps on how long the brand will cover each aspect of the window, such as glass, hardware, etc. We prefer a lifetime warranty, which covers all aspects of the window for its lifespan. If this is the coverage you want, consider Castle or Window Nation.
Customer Reviews
Renewal by Andersen has an A+ rating on the BBB and has been accredited by the organization since 1997. It has 3 out of 5 stars from more than 420 reviews on BBB and 2 out of 5 stars from 135 customers on Trustpilot. However, we believe the larger sample size on BBB is a more accurate reflection of customers’ experiences. We consider these to be average to slightly above-average customer ratings when compared to the other 14 companies we reviewed.
Happy customers report liking the quality of their Renewal windows and note that the installation team was punctual, knowledgeable, courteous, and respectful of their home. Not-so-happy customers say their windows showed up damaged or incorrect when unboxed, something we’ve seen in other companies’ reviews. Another negative theme for Renewal and several other brands is long wait times for installation or repair services. While both of these issues are a pain, we don’t consider them a red flag because they’re usually caused by supply chain delays and factory packaging, which installers have no control over.
Pros and Cons
What We Liked
- Offers a lifetime warranty, so all aspects of the window are covered for the window’s lifespan
- Has 24/7 customer support so you can call anytime
- Provides a 0% down loan option so you can buy windows with no cash upfront
What We Didn't Like
- Sells only vinyl windows, which aren’t as durable and efficient as other options
- Doesn’t sell picture windows, a rarity in the industry
Our Review
Castle earned 4.7 out of 5 stars. Its biggest selling point is its true lifetime warranty, the best type of warranty you can get. This warranty covers glass, framing, hardware, screens, installation, repairs, and more for the window’s lifespan. As with the other brands in our top five, this coverage is transferable, meaning you can pass it on to the next homeowner if you sell your house.
We also like how accessible Castle’s customer support team is. It’s the only company we reviewed that provides 24/7 support, and only one out of two that has customer support hours seven days a week. Most competitors are only reachable Monday through Friday during traditional business hours, with some offering a few hours on Saturdays. You can also reach Castle by using the chat feature on its website. This is a convenient way to get a quick answer to a simple question.
Our main complaint about Castle is that it only sells vinyl replacement windows. This isn’t unique—the same is true for 9 out of 15 of the brands we researched. However, vinyl is one of our least favorite materials. While it’s budget-friendly and typically more durable than aluminum, it’s less energy-efficient and durable than wood, fiberglass, or composite. We think it’s best to pay more for a better material so you can increase your return on investment. If your budget is tight or you prefer vinyl windows, we recommend Window World instead. The company is in our top five and is about $410 cheaper per window than Castle, according to our survey data.
Customer Reviews
Castle has an A+ rating on BBB and has been accredited by the organization since 1992. Its customer ratings across review sites (3.1 out of 5 stars on BBB and 3.8 out of 5 on Trustpilot) are average to slightly above-average compared to competitors.
We were happy to see in the customer reviews that Castle not only offers a lifetime warranty, it stands behind it. We read several reviews praising the company for honoring warranty claims. The same is true for its customer support. Many customers said the representatives they spoke to were helpful, pleasant, and efficient in solving issues. We also noticed Castle’s reviews mention good product quality more than those of other brands.
There wasn’t a strong negative theme among the reviews. Most complaints were niche issues, such as a broken seal or missed appointment time. The most common complaint that seemed to drag ratings down was pushy door-to-door salespeople. This doesn’t reflect the quality of the company’s products and services, and it may just be an issue at a few locations.
Champion
Best Financing Pros and Cons
What We Liked
- Offers the best financing perks of any brand we reviewed
- Is the only brand we evaluated that sells glass block privacy windows
- Has more customer reviews than any other company on our list, indicating popularity
What We Didn't Like
- Only sells vinyl windows, which aren’t as high-quality as fiberglass or composites
- Has complaints about responsiveness and missed appointments
Our Review
Champion Windows scored 4.6 out of 5 stars. We’re most drawn to its valuable financing offers.
Champion’s financing program is what sets it apart. If you need windows now but don’t have a lot of cash saved up, it could be a great option.
Champion offers loans with a 0% interest rate, which isn’t common according to our research. You also don’t have to put any money down or make any payments the first 12 months. The brand handles financing in-house, so you don’t have to independently get a loan from your bank. Plus, you get generous discounts, such as a buy two windows, get two free. If you’re upgrading windows throughout your entire home, this is a really helpful way to save money.
Champion’s biggest downside is that it only sells vinyl windows. Though this is an affordable material, it’s not the best long-term investment. Vinyl is common in the window industry, but it’s a much lower quality than wood, fiberglass, and composite materials. It’s not as energy-efficient or long-lasting, and we don’t recommend it if you live somewhere with high temperatures or severe storms because vinyl tends to warp and crack in these conditions. Fiberglass or composite windows are better choices for these climates.
Customer Reviews
Champion is one of two companies we reviewed that doesn’t have a BBB rating. This may seem concerning, especially because BBB displays an alert for the company pointing to a pattern of unreturned calls, canceled appointments, and delays. However, we read through over 200 reviews on BBB and didn’t see complaints about these issues any more than we see on other brand’s BBB profiles. We know from reading BBB’s accreditation criteria that companies must make annual payments, adhere to certain advertising criteria, and other actions that don’t reflect the company’s quality in regard to its customers. For these reasons, we’re not concerned about the current lack of rating, especially since we saw Champion have an A+ rating on the site earlier this year.
We trust Champion’s average customer rating of 3 out of 5 stars on BBB and its 4.1 out of 5 stars on Trustpilot, which is based on more than 3,600 customer reviews. These are above-average customer ratings. Customers note a high standard of professionalism among installers, though one negative theme is missed appointments. This could be a location-specific issue but still isn’t a good look for the company.
Window World
Most Budget-Friendly Pros and Cons
What We Liked
- Is the most affordable company of the 15 brands we scored
- Offers discounts and a 0% interest loan to help fit your budget
- Is the only company we reviewed that also installs shutters
What We Didn't Like
- Sells only vinyl windows, which aren’t as durable as other window materials
- Has a limited lifetime warranty, so it only covers select window parts
Our Review
We scored Window World 4.6 out of 5 stars. The company stands out for having the most affordable pricing on our list.
If you’re on a budget, Window World may be the way to go. According to our research, it has the lowest average prices by at least $400 per window, but it still maintains quality and scores highly enough in our rating categories to be in our top five. The company also offers discounts and a 0% interest loan at select locations.
In addition to windows, Window World installs entry and patio doors, siding, shutters, and garage doors. We like this for customers who have multiple home improvement projects, as you may be able to save money by bundling them.
Like a few other companies on our list, Window World’s main drawback is that it only sells vinyl windows. This is common for the industry, but we recommend a higher-quality material if you have the budget. Wood is a much more attractive and durable material, and fiberglass and composites are far more energy-efficient and weather-resistant. If your windows are exposed to intense heat in the summer or severe storms, don’t expect vinyl to hold up as well as these materials. You get what you pay for in this regard.
Customer Reviews
Window World has an A+ rating on BBB and an average customer rating of 4.1 out of 5 stars. This is one of the highest customer ratings we’ve seen on BBB, but the company doesn’t do as well on Trustpilot. There, it has just 2.3 out of 5 stars, which is average to slightly below average for that site.
We don’t see any significant reason why reviews on BBB are more positive than on Trustpilot. Positive themes across both sites are that installation was smooth, installers were professional and respectful of customers’ homes, and the windows look nice. The top complaint was that installers arrived with a product that couldn’t be installed, either because it was broken during shipping or wasn’t the correct order. We see this feedback in most companies’ reviews, and we know these issues have more to do with third parties than the company itself. We don’t see this as a big concern, as it sounds like this is an industry-wide problem given how many shipments go out daily and that windows are a delicate product.
Window Nation
Best Discounts Pros and Cons
What We Liked
- Sells wood windows in addition to vinyl—the only wood option in our top five
- Includes a true lifetime warranty, meaning windows are fully covered for their lifespan
- Offers buy-one, get-one discounts and discounts for veterans and seniors
What We Didn't Like
- Is one of two of the 15 brands we rated that doesn’t sell picture windows
- Can be difficult to reach
Our Review
We scored Window Nation 4.3 out of 5 stars. Its standout is its lifetime warranty coverage.
Window Nation is a good brand to consider if you want wood windows. Less than half the brands we reviewed sell wood options, and Window Nation is the only one that made our top five. Wood is durable and decently energy-efficient, and many homeowners like its classic curb appeal. However, we don’t recommend it for climates with a lot of moisture. Avoid wood if you live in a coastal area, as the humid, salty air will wear down your windows and shorten their lifespan. Window Nation also sells vinyl windows, which have a lower price tag but aren’t as durable or efficient as wood.
We like Window Nation’s lifetime warranty. It’s one of only two brands on our list with this kind of coverage length for all of its products and window parts. We also like the variety of discounts Window Nation offers, such as a buy one, get one free deal and a 5% discount for veterans, active military members, and seniors.
Unlike many companies on our list, Window Nation doesn’t have any other perks to help you save money. It doesn’t provide other home services, have 24/7 customer support, or sell picture windows, a customer favorite. These downsides caused it to lose points in key rating categories, putting it at the bottom of our list but still in the top five.
Customer Reviews
Like Champion, Window Nation doesn’t have a BBB rating. As we explained above, this could be for reasons that aren’t a reflection of the company’s product or service quality, such as not making its annual BBB payment. In this case, we saw that the company’s BBB profile displayed an alert about how the company advertised a vacation voucher. It looks like BBB flagged this promotion because it violates the organization’s advertising rules. Vacation vouchers are just an added travel incentive and don’t have anything to do with Champion’s windows, so we’re not concerned about the lack of rating.
Champion has 3.2 out of 5 stars from customers on BBB and 2.8 out of 5 stars on Trustpilot, which are both average ratings. We saw a lot of reviews from repeat customers, which is a good sign to us. Repeat customers expressed being just as happy the second time around with how fast and well-done their installation was and how much they love their windows.
A consistent negative complaint was that Window Nation’s installers arrived with the wrong windows. We’ve seen this in a few other brand’s reviews, but it was more consistent with Window Nation. There may be a miscommunication issue during the consultation when the order is placed or throughout Window Nation’s papertrail as the order is processed. We recommend asking for a copy of your order in writing in case you experience this issue.
FAQ About the Best Replacement Windows
Who makes the best replacement windows for the money?
We chose Renewal by Andersen as the best replacement window. According to our survey data, the brand’s average window price of $1,194 is below industry standard, yet Renewal by Andersen is known for its energy-efficient windows, professional in-house installation service, and unique, high-quality Fibrex composite frame material.
Which replacement windows last the longest?
Replacement windows last varying amounts of time based on their frame material quality. Lower-quality materials such as aluminum and vinyl typically last 20–30 years. A midtier material such as wood can last 30 years if well maintained. Fiberglass windows last the longest, potentially up to 50 years, if well cared for. Pella makes fiberglass windows that come with a limited lifetime warranty, which is the best combination of long-lasting material and a lengthy warranty.
How much should you spend on replacement windows?
Our survey of 1,500 window customers showed that the majority paid between $1,500 and $2,000 per window. However, many high-quality brands with more affordable prices don’t skimp on quality, such as Renewal by Andersen, Window World, Champion Windows, and Castle. These companies fall in the $800–$1,250 range on average, which we feel is a much more realistic amount to budget for per window.
What is the No. 1 window company in America?
Andersen is one of the most popular and awarded window companies in America, with more than 120 years in the window industry. We surveyed 1,500 homeowners and learned that 21% chose Andersen, while 15% chose Renewal by Andersen, Andersen’s child company.
What windows are comparable to Andersen?
Castle and Champion Windows rate similarly to Andersen regarding product quality and customer satisfaction.
