4. Andersen Windows Cost In 2026: Prices For Every Series, And How Renewal Differs

Andersen sells its windows in five main series, and the price of a replacement window swings from a few hundred dollars to several thousand depending on which one you pick. Add the fact that Renewal by Andersen is sold as a separate, fully installed product, and it gets hard to tell what a fair number looks like. This guide lays out what each Andersen series costs installed, what moves the price, and how to check a quote before you sign it.

The short answer: Andersen windows cost about $400 to $4,000 per window installed in 2026, according to HomeGuide’s national cost data. The entry-level 100 Series runs about $400 to $1,500, the popular 400 Series about $500 to $3,000, and the architectural A-Series and E-Series about $1,000 to $4,000. Renewal by Andersen is a different product sold as an installed package, at roughly $1,500 to $5,000 per window.

We’re Forshaw of St. Louis, and we sell and install Marvin windows, not Andersen. That gives us a stake in this topic. Andersen is one of the most respected window makers in the country. If you’re pricing one of its series, we’ll show you the Marvin line to price beside it, so you can compare two good options instead of guessing.

Andersen windows cost by series

Andersen’s series set the price more than anything else. The 100 Series is the entry point, the 200 and 400 Series are the wood-interior middle, and the A-Series and E-Series are the architectural lines. Here is what each one is made of and what it costs per window, unit only and installed, from HomeGuide’s cost guide:

Andersen series	What it’s made of	Window only	Installed cost per window
100 Series	Fibrex composite inside and out	$300–$1,000	$400–$1,500
200 Series	Wood interior, Perma-Shield vinyl exterior	$350–$2,000	$450–$2,500
400 Series	Wood interior, vinyl exterior	$400–$2,500	$500–$3,000
E-Series	Wood interior, aluminum exterior	$900–$3,300	$1,000–$3,800
A-Series	Wood interior, fiberglass and Fibrex composite exterior	$1,000–$3,500	$1,100–$4,000
Renewal by Andersen	Fibrex composite, sold installed	Not sold separately	$1,500–$5,000

The materials column comes from Andersen’s own compare and product pages. A few things are worth knowing about each series before you look at a quote:

• 100 Series. Andersen’s lowest-priced line, along with the 200 Series, built from Fibrex, a composite of wood fiber and thermoplastic that Andersen describes as twice as strong as vinyl. Our guide to what Fibrex is covers the material in detail.
• 200 Series. A wood-interior window in Andersen’s most popular sizes and most requested options. Andersen pitches it as “value that is unmatched in a wood window.” Fewer window types and choices than the 400 Series.
• 400 Series. Andersen calls it its most popular series. Same wood-inside, vinyl-outside construction as the 200 Series, with more window types, sizes, colors and hardware.
• A-Series and E-Series. The architectural lines, with the most design freedom. Andersen says the E-Series comes in 50 standard colors, with “dramatic sizes” and “dynamic shapes.”

Some national guides run lower than these numbers. Modernize’s 2026 guide, for example, puts the 400 Series at $700 to $2,100 installed. The spread between guides is a good reminder that the only number that counts is a written quote for your openings.

What Andersen’s own prices leave out

Andersen shows a few list prices on its website, and they look low next to the ranges above. On its compare page, a 100 Series awning window is listed at $480 to $720 and a 400 Series awning at $580 to $860. The A-Series and E-Series show “Request a quote” instead of a price.

Those are product prices only. Andersen’s pricing page says so directly: “Andersen® product pricing is determined by others based on the options, upgrades and other adjustments selected. Installation is not included.” In other words, the dealer or store sets the final price, and installation is extra.

Andersen window prices by window type

The kind of window matters almost as much as the series. A picture window has no moving parts, so it’s the least expensive to make. A bay or bow window is three or more units joined together, so it’s the most expensive. HomeGuide’s installed prices by type, across Andersen’s series:

Window type	Installed cost per window
Picture	$300–$1,500
Double-hung	$350–$1,500
Gliding (sliding)	$350–$1,500
Awning	$400–$1,500
Casement	$400–$2,000
Bay or bow	$1,600–$4,000

Not every type comes in every series, so ask which series a quoted window belongs to. The top of each range is where the larger sizes and the higher series sit.

What a whole house of Andersen windows costs

A typical home has somewhere around 10 to 15 windows. ConsumerAffairs puts the average home at about 10 to 12. Using HomeGuide’s installed ranges, here is how the total moves with the series you choose for 12 windows:

Series	12 windows installed
100 Series	$4,800–$18,000
400 Series	$6,000–$36,000
A-Series	$13,200–$48,000

Those ranges are wide because they cover everything from small, standard-size windows to large or custom ones with upgraded glass. Most homes don’t sit at either end. The takeaway is that series choice is the biggest lever you control, and the second biggest is the mix of window types.

Why two quotes for the same Andersen series come out so different

Two quotes for “400 Series double-hungs” can land far apart, and neither one has to be wrong. The difference usually comes from what’s inside the quote, not the brand on it:

1. Size and type of each opening. A large casement costs more than a small picture window in the same series. A quote is really a list of windows, not one price times a count.
2. Options and glass. Colors, interior finishes, hardware, grilles and glass packages are all priced as adjustments. Andersen says its own pricing depends on “the options, upgrades and other adjustments selected.”
3. Insert or full-frame replacement. An insert slides a new window into the existing frame. A full-frame replacement removes the old frame down to the rough opening, which takes more labor and more trim work. Older homes with rotted or out-of-square frames often need full-frame. Our guide to insert vs. full-frame replacement explains how to tell which you need.
4. Labor. HomeGuide puts installation at $100 to $500 per window, based on two installers spending about an hour per window on the ground floor. Second-story openings, tight access and repairs to the opening add time.
5. Who’s selling it. Because Andersen doesn’t set retail prices, the same window can be priced differently by a home center and a dealer. Installation, warranty on the labor and service after the sale vary too.

Where Andersen windows are sold

The 100, 200 and 400 Series are sold through home centers such as The Home Depot as well as through Andersen dealers. For the A-Series and E-Series, Andersen’s own compare page shows “Request a quote” rather than a price, so expect to work through a dealer or an installer for those.

Buying the window and buying the installation are often two separate things with Andersen’s retail series. When you compare, make sure each quote says who installs the windows and who stands behind that work.

Andersen vs. Renewal by Andersen: same parent company, different product

Renewal by Andersen is the part of Andersen that sells full-service window replacement. It uses its own Fibrex windows, sells through an in-home consultation, and prices the window, measurement and installation together as one package. HomeGuide puts Renewal at $1,500 to $5,000 per window installed and notes the package includes a 2-year installation warranty.

That’s why a Renewal quote and an Andersen 400 Series quote rarely line up. They’re different products, sold different ways. If you’re weighing a Renewal quote, our article on why Renewal by Andersen windows cost what they do walks through the package line by line.

How to read an Andersen quote

Before you compare Andersen quotes, or put one next to another brand, check that each one spells out the same things:

• The exact series and window type for every opening, not just a total.
• Insert or full-frame replacement, opening by opening.
• The glass package, including Low-E coatings and any upgrades.
• Interior finish, exterior color, grilles and hardware.
• Installation, including trim, interior and exterior finishing, and haul-away of the old windows.
• Warranty on the windows and warranty on the labor. Andersen’s 100, 200, 400, A-Series and E-Series carry 20 years on the glass and 10 years on non-glass parts, and the coverage transfers to the next owner. Labor coverage comes from whoever installs the windows.
• Timeline from order to install.

Two quotes that match on every line are a fair comparison. Two that don’t are comparing different jobs.

What to price beside each Andersen series

Every Andersen series has a Marvin counterpart that’s built for the same buyer. We sell Marvin, so we’d ask you to price both. Here is how the lines match up by construction:

If you’re pricing	Price this Marvin line beside it	Why they’re a match
Andersen 100 Series	Marvin Essential	Both are one material inside and out: Fibrex composite for Andersen, Ultrex fiberglass for Marvin
Andersen 200 or 400 Series	Marvin Elevate	Both put real wood on the inside and a low-maintenance exterior: vinyl for Andersen, Ultrex fiberglass for Marvin
Andersen A-Series	Marvin Elevate or Marvin Ultimate	Wood interiors with composite or fiberglass exteriors, aimed at architectural detail
Andersen E-Series	Marvin Ultimate	Wood interiors with aluminum exteriors, the widest range of colors, sizes and custom options in each brand

If you like a clean, contemporary look, Marvin’s newest collection, Vivid, is worth a look too. It pairs an Ultrex fiberglass exterior with a fiberglass-reinforced composite interior and comes as casement, awning and direct-glaze windows.

On price, This Old House’s 2024 survey of window buyers put Marvin at $400 to $1,925 per window installed, which overlaps Andersen’s retail series. The only way to know which is the better value for your home is two written quotes for the same openings. That’s what we’ll give you.

Frequently asked questions

What’s the average cost of an Andersen window?

Andersen windows cost about $400 to $4,000 per window installed, according to HomeGuide. The window itself runs about $300 to $3,500 and installation adds about $100 to $500 per window. The retail 100, 200 and 400 Series sit in the lower part of that range. The A-Series, E-Series and large bay or bow windows sit at the top.

What is the price difference between the Andersen 100 and 400 Series?

The 400 Series costs more. On Andersen’s own compare page, a 100 Series awning window is listed at $480 to $720 and a 400 Series awning at $580 to $860, before installation. HomeGuide’s installed ranges are $400 to $1,500 for the 100 Series and $500 to $3,000 for the 400 Series. The 400 Series has a wood interior with a vinyl exterior and more sizes, types and options. The 100 Series is Fibrex composite inside and out.

Which is more expensive, Pella or Andersen?

They’re priced in the same range. HomeGuide calls them the two biggest competitors in residential windows “with similar pricing,” with Andersen at $400 to $4,000 per window installed and Pella at $300 to $3,500. The series or line you choose, and the options on it, matter far more than the brand. Our Marvin vs. Pella comparison covers how Pella’s lines stack up.

How much do windows cost for a 2,000 square foot house?

A house that size commonly has about 10 to 12 windows. At HomeGuide’s installed range for the Andersen 400 Series, 12 windows would come to roughly $6,000 to $36,000. The series, the window types and whether you need insert or full-frame replacement decide where your project falls in that range.

Does Andersen publish a price list?

No. Andersen doesn’t publish a full price list or an online cost calculator. Its compare page shows list-price ranges for some series and “Request a quote” for the A-Series and E-Series. Andersen’s pricing page says product pricing is set by the seller based on the options chosen, and that installation is not included.

Is Renewal by Andersen the same as Andersen windows?

No. Renewal by Andersen is Andersen’s full-service replacement business. It sells Fibrex windows as an installed package through in-home consultations, at roughly $1,500 to $5,000 per window installed according to HomeGuide. Andersen’s retail series are bought through home centers and dealers, with installation priced separately.

Are Andersen windows worth the money?

Andersen is one of the leading window makers in the country, and all five of its retail series carry a 20-year warranty on glass and a 10-year warranty on other parts that transfers to the next owner. Whether a given series is worth it depends on matching it to your home and your plans. The best way to judge is to put a written Andersen quote beside a quote for a comparable line from another maker, for the same openings.
