Sooner or later, nearly every homeowner who stays in their home for any length of time will have to perform a major remodel. For some, it’s a roof. For others, it’s siding. For many, it’s windows.
Many brands of windows are designed to last around 20-30 years. That’s a long time, but if you’ve moved into your forever home and the windows have been around for a while already, there’s a good chance you’re due for new windows already.
Just take a look at your current windows.
- Are they difficult to open or close? Stuck, warped windows can be difficult to use, and that makes life just that much harder. It’s even a safety hazard if those are egress windows!
- Are they drafty? Older windows tend to end up with gaps around the seals where air can infiltrate. Very old windows might even have single-pane glass that provides next to no insulation against the elements.
- Are they cloudy or foggy? Double-pane windows are sealed so the air in between the panes is effective insulation, but those seals can fail over time. When moisture intrudes, it can condense and build up inside the windows themselves, making them worse to use, worse performing, and potentially even fostering mold.
- Is there damage on or around them? Older windows can be a source of moisture intrusion into the walls around the sills and the windows themselves, and that can cause hidden damage that builds up over time.
If it’s time to replace your windows, you have a choice to make. What window brand do you pick? Two of the giants here in New Jersey are Marvin and Andersen, and with good reason. Both brands have been around for ages, offer excellent windows, and are popular choices for everything New Jersey can throw at them.
Unfortunately, that means it can be very tricky to decide which one is the better option for your home. The good news is that’s where we come in! Read on for our comparative guide between these two popular window brands, or reach out to contact us directly for our recommendations for your specific home.
Andersen Windows: Series, Materials, and More
Andersen, in general, is a window manufacturer with a wide range of options to suit pretty much any possible need. They offer budget lines and vinyl replacement windows, and they have a special composite material known as Fibrex® that stands out as a durable, resilient material for long-lived windows. Their premium window options are still usually quite affordable, as well.

Andersen offers a range of different product lines, each with their unique benefits.
- Renewal by Andersen, a full-service window replacement line that typically offers vinyl windows custom-made for your home.
- Andersen Aluminum, formerly known as Heritage, their aluminum windows, providing metal construction that stands up against the elements.
- 100 Series, the premium Fibrex® composite windows made for long lifetimes with low maintenance, high energy efficiency, and sustainable creation.
- 200 Series, a vinyl-clad wooden design that has limited styles and options, but offers beautiful wooden interiors and an affordable price point.
- 400 Series, a vinyl-clad wooden line that offers more flexibility at a higher price point than the 200 Series.
- A Series, with wooden interiors and composite exteriors, made for customization and high thermal performance.
- E Series, the premium wood-and-aluminum line with stunning architectural designs.
With such a broad range of products across different materials, there’s something for pretty much everyone from Andersen.
Marvin Windows: Series, Materials, and More
Marvin is also a popular manufacturer of windows here in New Jersey, and with good reason. Their product lines span most common needs, but they excel in custom-made and uniquely designed windows that stand out from the average windows your neighbors have. With a high degree of customization and a design engineered for high performance, Marvin windows are some of the best on the market.

Not to be outdone, Marvin offers five product lines, each with a wide range of designs and styles.
- Marvin Essential, a line of simple, fiberglass windows with a focus on utility and durability. The designs are simpler, but the price point is very affordable.
- Marvin Elevate, the “step above” windows with fiberglass exteriors but stunning wooden interiors. They’re strong, stylish, and available to most budgets.
- Marvin Signature Ultimate, their broadest and most varied product line, with aluminum exteriors and wooden interiors. The perfect match of form and functionality is usually found in the Ultimate line.
- Marvin Signature Modern, their specialty line for modern aesthetics on contemporary homes. Fiberglass with large glass panels makes for stunning visuals, while energy-efficient glass makes them high-performance.
- Marvin Vivid, their newest collection introduced at the end of 2025, with new products being added throughout 2026. This is their product line made after taking customer feedback, striking a perfect balance between design, functionality, and form.
While most of Marvin’s windows are made of fiberglass, it’s actually a proprietary version of fiberglass called Ultrex®, which is strong, water-resistant, and extremely low maintenance. These aren’t the old kinds of fiberglass that you might be used to from decades ago, that’s for sure.
Marvin vs. Andersen: Durability and Maintenance
When you’re buying new windows, you want them to last. We find that most customers expect at least 20, and more often 30+ years of lifespan out of their windows. It should take a lot to make you need new windows again.
Marvin windows and their custom fiberglass materials are very durable and long-lived. They can easily withstand everything New Jersey can throw at them, from hot sun, UV rays, winter colds, and even coastal air. Maintenance is very low, and you’re more likely to find the areas around windows failing than the windows themselves.

Andersen windows are similarly durable, but the durability can vary across their product lines. The lower-end Andersen vinyl windows will certainly last 20 years, but they’re marginally more likely to need replacement earlier. High-end Andersen windows, meanwhile, have stood the test of time and have been known to last even longer than your longest expectations.
Neither brand needs much maintenance. As long as you check seals once a year and make sure to address any issues you do find, all you really need to do is keep them clean so they’re beautiful throughout the lifetime of your home.
Marvin vs. Andersen: Designs and Aesthetics
Both Marvin and Andersen have a wide range of designs across their different product lines. Some are your typical windows, others are sleek modern designs, and some have a classic look to them.
Marvin stands out a little on this front with some of their custom windows with unique shapes. If you have uniquely shaped windows or want custom designs, you can get them from Marvin more easily.

Neither brand is truly better than the other on this front. It all depends on what you want for your home, what will fit your siding and your architecture, and what matches your overall aesthetic goals. With extensive catalogs, both Marvin and Andersen can meet your needs in some way or another.
Marvin vs. Andersen: Energy Efficiency
One of the biggest purposes of new windows is improving the energy efficiency of your home. After all, windows are just enormous holes in your walls, and if your choice of window isn’t energy-efficient, you’ll end up wasting a lot of energy on heating and cooling.
Both Marvin and Andersen offer Energy Star certified glass options. There are some minor differences between the two, with slightly different coatings on their glass. Additionally, the different materials (wood, vinyl, composite, fiberglass) all have different thermal properties.
Across the board, though, the two brands are largely comparable. Either way, they’re going to be way better than your old, worn-out windows, and that savings alone is going to be worthwhile.

Both Marvin and Andersen also have some window products that meet Passive House certification standards, which is a step above. Only specific products have these certifications, so if you’re interested, be sure to ask about them when you talk to us about your new windows!
Soundproofing can be another aspect of efficiency that is important for homeowners. Both brands offer varied soundproofing across their products. Marvin’s Modern line is the best for their soundproofing, while Andersen’s A Series is also excellent. Other products might not be better than your typical windows for sound, though.
Marvin vs. Andersen: Warranty
You want your windows to last, and under normal conditions, they will. What happens if there’s unexpected damage, a manufacturing defect, or another issue along the way? Fortunately, that’s where warranties come into play.

Both Marvin and Andersen offer 20-year warranties on their glass across their products. Marvin offers 10 years of warranty on their window frames, while Andersen warranties are as much as 20 years, though it depends on the product line; most are ten, and a couple are actually just five.
Installation and labor warranties vary and start at 5 years, though these warranties are only valid if the windows are installed by licensed and certified dealers of the brand. Magnolia Home Remodeling is fully licensed and certified for both brands, so we’re your trusted experts here in New Jersey.
Marvin vs. Andersen: Pricing
We know that budget is always going to be a concern with any home renovation project, and windows are no different. Fortunately, both Marvin and Andersen offer both premium windows and more affordable lines to suit your needs.
If you’re pushing every penny to its limit and need to make your budget go as far as possible, you’re more likely to get what you want out of Andersen. Andersen’s budget lines are more cost-effective for what you’re getting. Marvin’s lower-end lines are still mid-range as far as windows go.

Both brands have high-end premium window offerings, so if you aren’t constrained by budget, you can land some absolutely gorgeous windows from either brand. It’s worth mentioning that if you’re aiming for custom windows from Marvin, they often have a longer lead time, so you’ll want to get started early to have them in time for your remodeling project.
If you’re struggling with the price of these two brands, you have other options as well. Companies like Pella offer more budget-friendly windows, for example. Alternatively, we offer financing for home remodeling and renovation projects to help make your projects happen when they need to happen, not when the pocketbook works out.
Which is Right for Your New Jersey Home: Andersen or Marvin Windows?
When it comes time to make a decision, which is the brand we’d recommend?
The answer is: either one!
Truthfully, both Marvin and Andersen windows are excellent. We’ve installed thousands of them all throughout New Jersey over the last 30+ years, and they definitely hold up.

Which brand has the edge depends on your specific needs. Marvin offers some excellent contemporary designs, especially with their Modern line, while their Ultimate line has some timeless, classic styles that work very well for historic homes. Andersen windows are excellent, especially along the coast, where their materials are resilient to seaside air, and they fit coastal homes incredibly well.

Frequently Asked Questions
How do I know when it’s time to replace my windows?
If your windows are difficult to open or close, feel drafty, appear cloudy or foggy between the panes, or show visible damage around the frames and sills, it’s likely time for a replacement. Most windows are designed to last 20–30 years, so if yours are approaching or past that age, new windows can improve comfort, energy efficiency, and safety in your home.
What are the main differences between Marvin and Andersen windows?
Marvin excels in custom designs and uses a proprietary fiberglass material called Ultrex® known for its durability and low maintenance. Andersen offers a broader range of budget-friendly to premium options using materials like vinyl, wood, and their proprietary Fibrex® composite. Both brands are Energy Star certified, offer strong warranties, and are built to handle New Jersey’s climate. Your best choice depends on your budget, design preferences, and performance needs.
Which brand is more affordable — Marvin or Andersen?
If budget is your primary concern, Andersen generally offers more cost-effective options at the lower end of their product lineup. Marvin’s most affordable line still falls in the mid-range price category. However, both brands offer premium, high-end windows at comparable price points. Financing options are also available through Magnolia Home Remodeling to help make your window replacement project more accessible regardless of which brand you choose.
Are Marvin and Andersen windows energy efficient?
Yes, both brands offer Energy Star certified glass options and will significantly outperform older, worn-out windows. Certain products from each brand also meet Passive House certification standards for even higher efficiency. The specific energy performance varies depending on the product line and materials chosen — wood, vinyl, fiberglass, and composite each have different thermal properties. Either brand will help reduce your heating and cooling costs substantially.
What kind of warranties do Marvin and Andersen offer?
Both brands provide 20-year warranties on their glass. Marvin offers a 10-year warranty on window frames, while Andersen’s frame warranties range from 5 to 20 years depending on the product line. Installation and labor warranties start at 5 years but are only valid when windows are installed by a licensed, certified dealer. Magnolia Home Remodeling is fully certified for both Marvin and Andersen, ensuring your warranty remains protected.
