Renewal by Andersen
4.1
Our Rating
As the child company of long-time window industry leader Andersen Windows & Doors, Renewal by Andersen specializes in white-glove window replacement services. The company’s long-standing A+ BBB rating reflects its commitment to hassle-free installation processes and master workmanship that only comes with Renewal by Andersen windows.
I recommend Renewal by Andersen because of its commitment to high-quality windows and increased curb appeal for customers.
Every window features the company’s patented Fibrex framing. This material, made of wood composites and polymers, provides maximum strength and weathertight protection. According to Renewal by Andersen’s website, Fibrex offers the durability of wood with the low-maintenance efficiency of vinyl. Because the material consists of reclaimed materials and lasts for decades, the manufacturing process produces less landfill waste.
Each Renewal by Andersen window replacement follows the company’s signature service process from consultation to cleanup. After a smooth installation, your Renewal by Andersen team will walk you through product operation and maintenance tips to ensure you’re satisfied with your new windows. It’ll then clean up the project area and dispose of old windows and debris. After the team leaves, you’ll be all set to enjoy your new Energy Star-certified windows.
The main drawback of Renewal by Andersen is its warranty. It offers a limited warranty structure with 20-year protection for glass and Fibrex, 10-year protection for locks, hinges, and hardware components, and 2-year protection for installation. While the company is known for quality products and excellent workmanship, it still might not be the best option for those seeking robust, lifetime replacement window warranties.

Champion
4.3
Our Rating
Champion earns a score of 4.3 out of 5 stars and the title “Best Customer Service” for its reliability and long-time presence in the window replacement industry. With 70 years of experience providing quality installations to American homeowners, Champion is an excellent choice for your next window replacement project.
Champion excels at customer service, offering free quotes and consultations in-person and virtually. If you’d prefer a virtual consultation, a Champion professional will meet with you via a video call to discuss quote options and provide live product demonstrations. From there, you’ll receive a project estimate on the spot.
Perhaps the most notable feature of Champion is its thorough installation process. Champion window experts follow a six-step process from arrival to finishing touches to ensure your home’s installation goes smoothly. Once its team conducts a final inspection of its work, it’ll clean up the area and discard old windows, leaving your home better than before.
Champion also offers a robust product list with nine window types and several glazing options. All products and installations feature lifetime warranties to cover necessary repairs, parts, and labor should any problems arise after installation.
Learn More: For more information, visit our full review of Champion Windows.
While Champion’s service and product offerings are top-of-the-line, the company does have some downfalls. It’s not accredited by the Better Business Bureau (BBB), which is a useful tool for learning about a company’s reputation and reliability. Despite its lack of accreditation, Champion has a 3.9 out of 5-star customer review rating on the BBB site, which indicates that most customer reviews are positive.

Window Nation
3.8
Our Rating
Window Nation’s score of 3.8 out of 5 stars and “Most Customization Options” title reflects its highly customizable window selection and multiple frame material options. Along with its dedication to specialized window and door products, it commits to customer education with its home improvement visualizer tool and resource library.
Window Nation provides a wide range of customization options for various homeowner needs. According to the provider’s website, it has over 1,500 custom window and door style combinations. That means you can fine-tune nearly every aspect of your window replacement to ensure the product is right.
The company offers eight window styles, two framing materials, and seven glass options for better energy efficiency. Pair those features with Window Nation’s interior and exterior color options, and you have a true custom window.
Window Nation shines when it comes to specialty windows. While some companies only offer basic specialty items like transom or picture windows, Window Nation consults with every customer to build a custom window for their home. So, if you’re seeking a unique circle, half-circle, triangle, or even hexagon window to enhance your home, Window Nation can deliver.
The main downside of Window Nation is that it’s unavailable in every state. While the company has grown tremendously since its inception in 2006, it still only has 20 showrooms across the U.S. Locations mainly span the eastern half of the country, so residents in the Midwest and West Coast might not have convenient access to Window Nation products.

Universal Windows Direct
4.0
Our Rating
Universal Windows Direct (UWD) gets 4 out of 5 stars and our ranking as the “Most Affordable” window replacement company. In addition to providing high-quality, cost-effective window products, the company also offers siding, doors, roofing, gutter protection, and attic insulation services to improve your home from top to bottom.
My industry research shows UWD is one of the most affordable brands available. With replacement prices ranging from $350–$550 per window, you can update your home and improve its curb appeal for less. Along with its lower-than-average prices, the company offers frequent discounts and custom financing options to make window replacement more affordable.
A solid warranty supports UWD’s competitive prices to protect your investments after purchase. The company promises top-notch service by certified window installation experts who handle everything from setup to cleanup. However, should anything go wrong with your UWD products after the installers leave, the company will honor your purchase with its True Lifetime Warranty.
The warranty covers parts, materials, glass, framing, locks, hardware, and labor costs for the span of the buyer’s homeownership. Should the owner sell their home, the warranties are transferable to the next owner for up to 30 years.
One drawback of UWD is that it only sells seven window types. Most other top providers offer between eight and 10 styles, so some shoppers might find this selection a bit limited.
The company offers standard options like double-hung and picture windows, making it sufficient for basic replacement projects. However, if you’re seeking a specialized window shape or custom framing, you should consider a different provider.

Window World
4.3
Our Rating
I give Window World 4.1 out of 5 stars and the superlative “Best Window Selection” for its wide range of service offerings and product customization. The company has been in business since 1995 and has established itself as a leader in the home improvement industry. With over 200 locations nationwide, it offers installation services for windows, doors, shutters, siding, and more.
If you need specialty replacement windows to match the rest of your home design, Window World is a great place to start. It has the best product selection of any top provider in the market. In addition to offering 12 types of windows, the company provides customization for nearly every element of those windows — from the grills down to the hardware. Along with this high level of customization comes a limited lifetime warranty and durable, chip-free vinyl framing.
Window World is one of the only replacement companies offering single-hung window installation. Though experts accept double-hung windows as the more attractive option for upkeep and curb appeal, I like that Window World includes single-hung models in its catalog of replacement styles.
The company’s impressive product list allows shoppers to outfit many aspects of their home’s exterior in one place. If you’re considering a full exterior remodel, you’ll find windows, doors, and siding at Window World.
Despite Window World’s extensive selection of window products and customizations, the provider only offers vinyl window frames. Vinyl is the most popular framing material on the market, but some homeowners prefer the traditional look of wood or the durability of metal.
If you’re one of these shoppers, the company might not be the best option for your home’s window replacements. However, if aesthetics are the only thing holding you back from Window World’s vinyl frames, consider one of its woodgrain finishes to achieve the look you want.

Castle Windows
3.9
Our Rating
I awarded Castle Windows 3.9 out of 5 stars and the title “Best Window Warranty.” The family-owned company has an established reputation as one of the most trusted providers in the window replacement industry. Since its inception in 1977, Castle Windows has proven its dedication to customers with outstanding product warranties and long-standing BBB accreditation.
Castle Windows is the best choice for homeowners seeking comprehensive, long-term warranty protection for their replacement windows. The company provides lifetime guarantees on windows and workmanship, giving customers some of the best buyer protection in the industry.
Castle’s protection applies to window units, glass, and labor, as long as the windows remain in their original openings. Even if you sell your home, its Castle Windows will retain non-prorated protection with transferable lifetime warranty coverage.
Castle provides customers with additional support in its troubleshooting and service guides. The troubleshooting guide provides extensive window maintenance and repair information, and the service guide video tutorials visually demonstrate how to care for your Castle Windows products.
One limitation of Castle Windows is that it’s only available in 11 states. If you don’t live in Connecticut, Indiana, Maryland, Michigan, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Virginia, or West Virginia, you might not have access to the company’s services.

What Should You Consider When Looking for a Good Window Replacement Company?
When shopping for any part of your home, you must consider many factors to ensure you get the best option. Windows are no exception, and finding a window replacement company that fits your budget, style, and service needs can save you money and time down the road.
Consider these factors when choosing a window replacement company:
- Product offerings
- Customization options
- Energy-efficient product options
- Warranty coverage fine print
- Industry reputation
- Real customer reviews
Let’s dive deeper into these factors below to give you a full understanding of what to look for in a reliable window replacement business.

Product Offerings
I suggest finding a window replacement company with a wide range of product offerings. This is important for a few reasons. Firstly, a company with a robust selection of window types and customization options is better equipped to meet your individual needs. More frame, glass, and hardware options allow you to invest in a product you love.
A wide product range is also important because it often signals a company’s expertise in home services. If you find a top-rated window replacement business that also installs patio doors, siding, or roofing, you can turn back to that company when other replacement needs arise for your home.

Energy Efficiency
Understanding how windows can enhance your home’s energy efficiency is a crucial step in the cost-benefit analysis of window replacement shopping. Advanced window designs are built for better insulation, less noise pollution, and higher energy savings.
Look for companies with Energy Star-certified window products. The U.S. Department of Energy rigorously tests these windows to ensure they provide greater efficiency and lower energy bills.
Many energy-efficient window brands use low emissivity (Low-E) glass that contains a thin layer of reflective coating to repel UV and infrared rays. The coating simultaneously reflects interior temperatures into your home, thus reducing the amount of heat transfer through the window.
The number of panes (glass layers) in your windows also contributes to your potential savings. Single-pane windows have one sheet of glass between the frames. Double and triple-pane windows have multiple glass layers, often separated by argon gas fills that prevent significant temperature transfer through the windows.
According to the National Association of REALTORS®, you can save up to $465 per year by replacing single-pane windows with double-pane ones. You can save about $100 annually by replacing existing double-pane windows with energy-efficient models.

Warranty Coverage
A window warranty is a manufacturer’s guarantee to cover defects or damage to certain window components for a set time after purchase. Many window warranties cover glass, hardware, framing, and sometimes installation to help homeowners protect their investment.
Unfortunately, not all window replacement warranties are straightforward. Some include unclear wording and easy-to-miss loopholes that leave customers confused and frustrated when they don’t receive the coverage they expected. For this reason, fully understanding a company’s window replacement warranty before signing a contract is crucial to your satisfaction and budget should any defects come to light.
Many window replacement companies boast a “lifetime warranty” for their products, which usually means the products are covered for as long as the original buyer owns the home. However, some companies only offer lifetime warranties on certain window components, so you’ll need to dig into a contract’s fine print for any year-specific provisions. The bottom line is that you should determine what the warranty covers before buying.

Reputation and Reviews
Explore a company’s online ratings, qualifications, and reviews before hiring them to install new windows in your home. You can assess the company’s Better Business Bureau (BBB) rating or read customer comments on sites like Google Reviews, Yelp, and Trustpilot.
The BBB is an excellent place to start when researching window company reputations. The organization catalogs and ranks companies based on factors like transparency, reliability, and honest business practices. Many of the top window replacement providers i ranked in this article are BBB-accredited, some with the highest possible rating of A+.
Reading real customer reviews is one of the most important way to vet a company before investing in its products. Before hiring a company, learning about other customers’ experiences can save you from poor service and faulty installations. A company might boast excellent service and speedy installation on its website, but then deliver the opposite. Real customers are likely to be candid, noting the good and bad aspects of their experiences with particular window companies.

How Much Do the Top-Rated Window Replacement Companies Cost?
Industry pricing for replacement windows ranges from $400 to $2,100, depending on the type of window you need.
Based on our research, I found that the following several factors typically affect window replacement costs.
- Material: The material you select for your replacement windows will affect how much they cost. Vinyl is typically the cheapest, most common option, while wood and composite windows tend to cost more. If you would like to choose the more affordable option, which is vinyl, I recommend buying from reputable vinyl window providers.
- Size: Unsurprisingly, the size of your new windows will significantly affect how much they cost. Smaller windows use fewer materials and, therefore, cost less. Larger types, like bay and bow windows, take more materials and installation time, leading to higher costs.
- Glass: Glazing can impact your overall replacement window prices. If you opt for double or triple-pane windows, impact glass, or customized tinting, your price tag will reflect it.
While shopping for window replacement quotes online, you’ll find that most companies don’t list pricing info on their websites. Window replacement generally involves a highly individualized consultation process in which a representative will assess your home and window needs before providing a quote. For more specific pricing information from a top provider, consider setting up a virtual consultation or calling its customer service line.
Read our article on the best inexpensive window replacement companies for more cost and company information.
The chart below shows the average cost ranges for each company I covered. The green rectangles represent the breadth and expanse of each provider’s replacement window prices, from least to most expensive.
What Types of Windows Do the Top-Rated Window Replacement Companies Offer?
Each replacement window company I covered has solid product selections with various window types for you to explore. However, the selections still vary, so you must ensure your chosen provider has exactly what you need.
I’ve compared each company’s product offerings below to give you a picture of potential gaps in your search.

For the widest selection of window types, I recommend Window World. The company offers everything from double and single-hung to high-performance impact windows for your home. It’s the only company on our list that advertises single-hung replacements, so it’s the best place to shop if you’re seeking this window type.
Renewal by Andersen has a narrower selection but offers a trusted installation process for the most common replacement window types you might need. Champion, Renewal by Andersen, Window Nation, Window World, Thompson Creek, and Castle Windows all offer specialty products to personalize your replacement windows. I suggest scheduling an in-home consultation with one of these companies if you need custom windows.

How Do You Know If You Need a Window Replacement?
Windows generally last 15–20 years, after which the components start deteriorating and losing efficiency. If your windows exhibit issues before their lifespan runs out, you may wonder if you need window repairs or replacements.
The lists below explain which scenarios require simple fixes and full replacements.
You might need window repairs if:
- The window frames or sashes show signs of chipped paint and cosmetic damage.
- The locks and hardware are difficult to maneuver.
- The weatherstripping becomes worn out or ineffective.
It’s time to replace old windows when:
- The windows show signs of imbalance or warped framing.
- The glass seal is broken, or condensation is present between panes.
- Your windows no longer provide UV protection and insulation.
- You’ve outgrown the look and style of your existing windows.
How Can I Save Money on the Top-Rated Window Replacement Companies?
If you need new windows, you may be worried about the upcoming cost. Fortunately, taking the time to assess your options and shop smart can save you hundreds of dollars on this investment.
Follow these tips to save money on your replacement windows:
- Collect multiple quotes from top-rated window providers. Gathering several quotes will give you a firm idea of how much your home improvement project will cost and what options are available.
- Ask about discounts. Some window providers offer discounts if you pay in cash or purchase multiple new windows at once.
- Stick with standard window options. Unique colors, hardware, and sizes cost extra, so if affordability is your top concern, stick with standard sizes and skip pricey customization options.

FAQs about Window Replacement Companies
What Is the Best Time of Year To Replace Windows?
Most window installers recognize late spring and early summer as the best times to replace windows. This time of year is often the mildest in most areas, making it easiest for installers to complete the projects without letting inclement weather into your home.
The downside to fall and winter replacements is the possibility of cold drafts entering the home, affecting indoor temperatures and bumping up energy bills. If you must replace your windows during the colder months, the installer can take steps to minimize the negative effects. For example, they can replace one window at a time or close off the room they’re working on to minimize drafts. They might follow this same process in extremely hot weather to minimize the amount of heat entering the home.
Homeowners in milder climates can replace windows anytime with fewer negative consequences. If you live in a mild climate, you may want to consider booking in the “off-season” of fall or winter to score potential deals and easier booking with your chosen installer.
What Are the Benefits of Replacing Old Windows?
The main benefit of replacing your old windows is your potential to access new window technologies. New window designs are specially crafted to provide sound reduction, energy efficiency, and style to your home than was possible with previous models.
Though the initial investment will seem high, new windows provide the possibility of cheaper utility bills, enhanced functionality, and higher home resale value. Learn more about how new windows can improve your home’s value in this article from Window World.
Are Replacement Windows Tax-Deductible?
As of 2023, energy-efficient replacement windows and skylights installed after January 1, 2023, are eligible for up to $600 in tax credits. To qualify for tax credits, your new windows must replace the existing ones on your primary residence and meet Energy Star’s Most Efficient criteria for home upgrade products. Visit the Energy Star website to determine if your windows are eligible for credits or rebates.
What replacement windows last the longest?
Fiberglass is the longest-lasting window material because it is warp, crack, and rust-resistant. While a bigger upfront investment, fiberglass windows can last years longer than flimsier materials like vinyl, giving you a strong return on investment.
Methodology: How We Evaluated Window Replacement Companies
At Today’s Homeowner, we strive to bring you the most transparent, accurate information for your home improvement projects. Our window company ratings emphasize what matters most to you—a wide range of well-designed products with reliable installation and great curb appeal.
Our ratings are based on publicly available information about each company, secret shopping online and over the phone, customer-review analysis, and discussions with renovation and building experts. A company can earn a maximum of 100 points across five categories, converted to a five-star scale. We researched dozens of windows installation and replacement companies to develop the following formula:
- Product Offerings (40 points): Window installers can earn the maximum point value in this category if they offer a wide variety of window styles, frame materials, hardware designs, and glass and coating options. Companies earn more points if they design custom windows for your home. We also score the quality and energy efficiency of the windows each company installs.
- Service Offerings (10 points): When evaluating this category, we consider factors such as consultations, post-installation cleanup, and additional product offerings. We also look at each company's installation team structure – including whether it uses certified window installers or subcontractors to complete work – as this can cause variances in quality.
- Affordability (25 points): Our affordability rating considers the provider’s average window prices and how they align with industry averages, as well as discounts and payment plans.
- Warranty and Support (10 points): A best-in-class window installer will back up its work with a solid warranty to give you added peace of mind. Companies receive the maximum point value in this category if they offer lifetime warranties for their products and workmanship.
- Company Reputation (15 points): To ensure we’re recommending worthwhile installers, we check each company’s reputation and standing with the Better Business Bureau (BBB). We also consider how many years of experience it has in the window industry.
We monitor company data on an ongoing basis to keep rankings and information up to date.
