Marvin is a window manufacturer with more than 110 years of experience selling residential and commercial windows. The company has an expansive network of dealers and installers in nearly all U.S. states. Unlike some brands, Marvin has several window lines to choose from, which allows you to select styles that suit your home’s look. 

Our team looked into Marvin’s website, window offerings, pricing, warranty coverage, and customer reviews to see how it stacks up to other top window brands. We believe the company is a solid option if you plan on buying fiberglass windows. However, other brands may offer better warranties and installation options at a more attractive price.

Our Take on Marvin Windows

Marvin is an industry-recognized manufacturer that has won several awards, such as the 2016 Minnesota Family Business Award, the 2017 Brand Leader Business Award, and the American Business Ethics Award. In our review, we scored Marvin a 4.2 out of 5 stars based on its wide product selection, years of experience, and solid glass warranty. 

We like Marvin’s commitment to innovation, sustainability, and energy-efficient windows. Its products meet or exceed industry standards from Energy Star and the National Fenestration Rating Council (NFRC). For example, Marvin offers various glass and frame material options, such as low-emissivity (low-E) coatings, double- and triple-pane glass options, and argon gas-filled window panes to maximize energy efficiency and insulation.

However, Marvin lost points in our review because it doesn’t provide a labor warranty and holds mixed customer ratings.

Types of Windows Offered

Marvin offers up to 13 types of windows, making it one of the most well-rounded window brands we’ve reviewed in terms of product selection. Two of its options—the corner window and Skycove glass structure—are unique offerings we haven’t seen other brands offer. 

According to Marvin’s website, the Skycove structure can add up to 20 square feet of space within your home since the structure sticks out of your home, similar to a bay window. These windows best suit contemporary homes with modern design elements. 

Alongside its unique offerings, Marvin sells many common window styles, such as single-hung and casement windows. In addition, Marvin provides a product help library on its website where you can browse care and maintenance guides, energy data, parts and warranty manuals, and more.

Marvin pairs its vast window style selection with three material options: aluminum, fiberglass, and wood. Of the fiberglass models, you can choose from high-density fiberglass or the company’s proprietary Ultrex fiberglass material. According to Marvin’s website, its Ultrex windows are eight times stronger than vinyl, which makes them suitable for extreme climates. However, if you’re specifically interested in vinyl windows, we suggest a different brand because Marvin doesn’t offer them.

Marvin Window Cost

According to our research, Marvin’s window prices tend to vary because the company makes windows on a per-order basis. Also, prices depend largely on the size and type of window, the amount you buy, and your location. Our team spoke with a Marvin representative who said the company typically prices most of its windows between $400 and $1,500 per window.

We also gathered pricing data by surveying 1,000 windows customers nationwide in 2024. Respondents who bought Marvin windows reported paying between $400 and $1,925 on average per window, which roughly matches the price range Marvin gave us. Marvin’s window costs are within the average replacement cost of $1,500 and $2,000 per window, meaning that Marvin prices its windows similarly to other national brands.

Financing Options

Like most window replacement brands, Marvin offers financing options. However, we didn’t find any information on the types of financing the company provides on its website. The customer service representative we spoke with said that Marvin outsources all of its sales and financing procedures to its network of authorized dealers. The representative added that financing terms and offers can vary by location, so your best bet is to contact your local dealer and ask about financing options.

Discounts and Ways To Save

During our call with Marvin’s customer service representative, we asked if the company provides any discounts for its products. The representative said discounts vary by authorized dealer. We recommend asking your local dealer about any discounts they may have when you request a quote.

Although Marvin doesn’t disclose information about discounts on its website, there are still ways to save on your replacement window project, which we highlight below:

• Select affordable window options: Marvin’s large variety of window styles and material options allow you to easily choose a more budget-friendly window. While you may want a large and beautiful wood bow window, a smaller and simpler design, such as a fiberglass picture window, can still provide striking views at a lower price.
• Get several quotes: Even if you plan on buying your windows from Marvin, we recommend requesting quotes from other window installation companies to compare prices, window options, and warranty terms. 
• Purchase during the off-season: Window installation companies generally have fewer jobs during the colder months. Your local Marvin dealer may offer additional labor discounts during the off-season since they may have a smaller workload.

Energy Efficiency

Marvin builds all of its windows and doors to meet or exceed the demanding energy-efficiency standards from Energy Star and the NFRC. We checked the product databases of Energy Star and the NFRC and found Marvin as a certified partner for both. 

According to Marvin’s website, the company can build windows that suit every climate in the U.S., such as Northern, North-Central, South-Central, and Southern climate regions. Some of the energy efficiency features that Marvin includes in its windows are the following:

• Argon gas fill: Argon gas is an insulating material that Marvin uses in between each glass pane of its insulated glass. The gas helps reduce condensation and heat conduction.
• Insulated glass: Insulated glass is another term for double- or triple-pane glass. The insulation occurs through the multiple layers of glass and insulating gas fill. These features prevent heat or cold from entering or escaping through the window.
• Low-E coating: Low-E coatings help reduce the amount of solar heat that can transmit through your window glass. Marvin offers various levels of low-E coatings to match your climate region.
• Weatherstripping: Weatherstripping—usually made of rubber or vinyl—prevents air leaks, drafts, and moisture from entering your home. It also helps regulate your home’s internal temperature by keeping warm or cool air in.

Warranty

We went on Marvin’s website and found the company provides a glass and hardware warranty for every window and door it sells. The company has different warranty terms for each window series and product line. 

We read the warranty terms of Marvin’s Elevate, Essential, and Signature window lines. While reading, we noticed that it lists installation as a warranty exclusion. Note that other quality window brands provide glass, hardware, and labor warranties for their products. 

That said, Marvin is still worth considering if you’re looking for cutting-edge windows available in many styles and materials. We break down Marvin’s Elevate, Essential, and Signature window warranties below:

• Exterior finish: 20 years for aluminum windows installed in standard environments; 10 years for aluminum windows installed in coastal environments; 10 years for composite windows installed in standard environments
• Glass: 20 years for glass under 60 square feet; 10 years for glass over 60 square feet
• Hardware and other nonglass components: 10 years for most hardware and nonglass components; five years for motorized hardware and components
• Interior finish: Five years for wood; 10 years for aluminum and composite

Quote and Installation Process

Marvin’s quote process is similar to other window brands that outsource window installation to authorized dealers or installers. On Marvin’s website, you must first find an in-network dealer near you to start the quote process. Using the company’s find a dealer page, we were able to locate dealers in every U.S. state except Alaska, Arizona, Nevada, South Dakota, Texas, and West Virginia. Once you select a dealer, you can fill out a consultation request form with your information.

An authorized dealer will review your request and schedule an in-person consultation with a window replacement expert. Marvin’s website doesn’t provide much information regarding its consultation and installation process. 

However, Marvin’s Infinity replacement window website sheds some light on its consultation and installation procedures. According to Infinity, it breaks the consultation and installation process into four steps: initial consultation, measurement consultation, window building, and installation. We outline each step in more detail below.

• Initial consultation: After you schedule a consultation with an authorized partner, a replacement expert will view your home, answer questions, provide recommendations, and place your order with Infinity.
• Measurement consultation: This step has a technician review your order, measure your window openings, and verify any installation needs.
• Window building: Once the measurement technician verifies your work order, Infinity will begin building your windows based on your specifications.
• Installation: The final step involves removing your home’s old windows and installing the new ones you ordered. Installation can take anywhere from a few hours to several days, depending on the size and difficulty of your replacement project. Infinity’s professional window installers will take care of the cleanup and instruct you on maintaining and using your new windows.

Customer Reviews

Although Marvin has an A+ rating with the Better Business Bureau (BBB) as of the time of this writing, the company has generally unfavorable customer reviews on the site. That said, we’ve found that most window brands we’ve reviewed tend to have poor customer reviews on the BBB since the site helps handle customer disputes. While we do take into account the experiences of customers on BBB, keep in mind that reviews might not paint a complete picture of a company’s reputation.

The main themes we found on Marvin’s BBB page include mixups on delivery dates and poor customer service when customers request a fix. Here are a few reviews we found:

“Ordered doors and windows for a whole house remodel based on project timelines around the dates Marvin provided. Marvin not only failed to meet delivery dates, they did not communicate changes in the schedule, and they did not appropriately follow up with damaged products. This has been a disaster, and I regret going with Marvin.” —Christy K. via the BBB, October 2024

“Customer service is a waste of time with Marvin. They just blame everything on the installer and leave the customer between a rock and a hard place. No explanation as to why they insist leaks are the installer’s fault. They just stick to that excuse no matter how many questions you ask so that you can even talk sensibly to an installer or other repair person about what’s happening. Other than the window leaks inside. No help whatsoever. I’m not buying from Marvin ever again.” —D.B. via Yelp, June 2024

We found more favorable reviews for Marvin on Google Reviews. Below are a couple of customer reviews we found:

“We had a consultation with Marvin through Costco. The Marvin representative arrived on time and was very respectful and communicative. I didn’t feel unnecessary pressure from him, and he worked with me to look at different options. He was personable and explained everything so that I completely understood what working with Marvin would look like. [I] will definitely be recommending them to friends and family!” —Chelsea W. via Google Reviews, September 2024

“The crew at Marvin replacement windows was excellent all around. They were on time and polite. They did a great job on the installation and totally cleaned up after they were done. Would highly recommend them.” —Christine W. via Google Reviews, May 2024
