Marvin Windows Review: Collections, Cost and Warranty (2026)

Marvin, founded in 1912 and still family-owned, is based in Warroad, Minnesota. Its five collections are sold through local dealers. Infinity by Marvin is a separate replacement brand with its own stores and warranty, and which of the two you’re quoted decides who stands behind the installation.

What Marvin sells

None of Marvin’s current collections is vinyl. Most are built on Ultrex, Marvin’s name for its fiberglass, and Elevate and Ultimate have wood interiors.

The names changed in April 2019, when Marvin retired the Integrity brand. Integrity Wood-Ultrex became Elevate and Integrity All-Ultrex became Essential. Ultimate and Modern were grouped for a while under a “Signature” banner. Marvin’s site now presents five collections with no Signature umbrella (the old Signature page returns an error), and the 2026 warranty names the same five.

• Essential: Ultrex fiberglass inside and out, and the lowest-priced collection in the third-party estimates below.
• Elevate: a wood interior with an Ultrex fiberglass exterior.
• Ultimate: the most customizable collection, wood inside with an aluminum-clad or wood exterior.
• Modern: a contemporary design with a high-density fiberglass exterior and an aluminum interior.
• Vivid: new, announced in September 2025. Ultrex outside, a fiberglass-reinforced composite inside. Marvin pitches it at “an accessible price point” but publishes no numbers. The launch range is casement, awning and fixed (direct-glaze) windows plus sliding, swinging and bi-fold doors, sold only in Texas, Colorado, Kansas, Montana, Idaho, Washington and Oregon for now. Marvin says more products and states are due in 2026, and that Vivid meets ENERGY STAR version 7.
• Infinity by Marvin: replacement windows in Ultrex fiberglass, with an EverWood interior option. It launched in 2002 as Infinity from Marvin and took its current name in 2025.

What Marvin windows cost

Marvin publishes no price list, and its windows aren’t stocked at Home Depot or Lowe’s, so there’s no supply-only shelf price to compare against. Here is what our model says for the two frame types Marvin uses, national figures before your city’s price level is applied:

Marvin frame	Double-hung, 3 x 5 ft	Casement
Fiberglass (Essential, Modern, Infinity)	$895–$2,205	$1,075–$2,645
Wood, clad exterior (Elevate, Ultimate)	$1,120–$3,495+	$1,345–$4,200+

Casements cost more per window than double-hungs in every frame, roughly 1.2 times as much (the cost guides we checked that split styles price them higher). Vivid launched with casements, awnings and fixed glass but no double-hung, so for its Ultrex frame the fiberglass casement figure is the nearest one.

The only collection-level estimates we found are third-party:

Collection	Modernize estimate, installed per window (updated Oct 6, 2026)
Essential	$900 to $1,200
Elevate	$1,000 to $1,400
Ultimate and Modern	$1,200 to $2,500

Modernize’s worked examples on the same page: ten Essential double-hungs in Dallas at $11,000 to $13,000, and fifteen Elevate casements in Chicago at $18,000 to $22,000. The page’s own summary table gives $500 to $1,500 per window, which doesn’t square with its detail. It has no Infinity figures, and we found none elsewhere.

What Infinity does publish is promotions. On October 30, 2026, Infinity Replacement’s Columbus, Ohio, page offered $2,000 off an installed project with a $12,000 minimum, plus $0 down and no payments or interest for 12 months, expiring November 30, 2026.

How buying Marvin works

Marvin collections. For replacement work, Marvin tells homeowners to “choose a local Certified Installing Retailer.” That retailer quotes, measures and installs, and it writes its own installation warranty. Marvin’s warranty covers the product, not the labor.

Infinity by Marvin. You can buy it from an independent Infinity retailer or from Infinity Replacement by Marvin, which describes itself as Marvin’s “full-service, turnkey replacement division” and sells through company-owned locations. It opened its 19th market, Northern Virginia, Maryland and Washington, DC, in May 2026. Its location menu lists Kentucky, Maryland, Massachusetts, New Hampshire, New Jersey, New York, North Carolina, Ohio, Oregon, Pennsylvania, Texas, Virginia, Washington and DC.

The Infinity Replacement process starts with a free consultation. A project manager then measures for custom-built units, and “trained specialists” install them. The company promises “no subcontractor guesswork” but doesn’t say whether its installers are employees. Independent Infinity retailers run their own sales process and pricing, and set their own installation terms.

We found no published lead times for either channel. If a quote leans on a financing offer, our window financing guide covers what to ask.

Marvin warranty

Marvin’s collections and Infinity carry different warranties, both in versions that took effect in January 2026.

	Marvin collections (effective Jan 12, 2026)	Infinity by Marvin (effective Jan 4, 2026)
Frame and non-glass parts	10 years	Lifetime for the original purchaser who owns and lives in the home, if registered within 60 days of installation; otherwise 10 years
Insulated glass seal	20 years under 60 sq ft; 10 years at 60 sq ft and larger	20 years
Exterior finish	Aluminum clad 20 years (10 in coastal settings); fiberglass 10 years	Fiberglass 10 years
Labor	Not included	Infinity may “provide and install a replacement component” under the lifetime term
Next owner	Fully transferable, terms counted from the original purchase date	Lifetime ends with the original owner; a buyer gets 10 years on non-glass parts and 20 on glass

A few details sit outside the table. Marvin covers stress cracks for 10 years and interior wood finish for 5. Claims go through the dealer within 60 days of the defect appearing, and the document includes class-action and jury-trial waivers. Infinity’s glass, coastal hardware and finish are always on the 10/20 terms, never lifetime.

Installation is where the two really part. Marvin’s warranty excludes removal, installation, finishing and disposal, and Marvin says the installer warrants the installation. Infinity Replacement adds a five-year installation warranty: it covers installation defects that damage the windows or doors, reported within five years, and the remedy is to correct the installation or refund that window’s installation fee. It excludes damage to other building materials and worn caulk, and disputes go to arbitration. Independent Infinity retailers write their own installation terms, and one partner page advertises a lifetime installation warranty.

Our window warranty comparison sets these terms beside other brands’.

What to check in a Marvin quote

1. The collection, by its current name. Integrity is a retired name, and Signature no longer appears on Marvin’s collections page or 2026 warranty. Coastline has its own 2023 warranty but isn’t on Marvin’s current collections page. If a quote uses any of the three, ask which 2026 collection and warranty you’re actually getting.
2. The installer’s labor warranty, in writing. On the five Marvin collections it’s the only labor coverage you’ll have, so get the term and what it covers on the contract.
3. Who registers an Infinity warranty. Without registration within 60 days of installation, the lifetime term drops to 10/20. Ask who files it and get the confirmation.
4. Large glass. On Marvin collections, a unit of 60 sq ft or more gets a 10-year seal term instead of 20. That matters for very large picture windows.
5. Interior finishing on wood collections. Elevate and Ultimate have wood interiors. Check whether the quote includes a factory finish or leaves the staining or painting to you, and note that Marvin’s warranty remedies exclude finishing and refinishing costs.
6. The price before any promotion. If a quote applies a dollar-off offer or no-payment financing, ask for the undiscounted price and the rate after the promotional period.

How Marvin compares

For a dealer-sold wood-clad or fiberglass window, the nearest comparisons are Andersen and Pella; Pella vs Andersen covers that pair. Infinity Replacement’s model of company-owned stores with installation included is closest to Renewal by Andersen, whose installation term is two years against Infinity Replacement’s five. In the western states, Milgard’s new C700 is another fiberglass line sold through dealers. Already holding a Marvin or Infinity bid?

Frequently asked questions

›How much do Marvin windows cost?

Marvin doesn't publish prices, and its windows aren't sold off the shelf at Home Depot or Lowe's. Our national model puts a 3 x 5 ft fiberglass double-hung (Essential, Modern, Infinity) at $895–$2,205 installed and a wood-clad one (Elevate, Ultimate) at $1,120–$3,495+. Modernize, updated October 2026, estimates $900 to $1,200 per window installed for Essential, $1,000 to $1,400 for Elevate and $1,200 to $2,500 for Ultimate and Modern.

›What happened to Marvin Integrity windows?

Marvin retired the Integrity name in April 2019, when it folded its brands into one Marvin brand. Integrity Wood-Ultrex became the Elevate collection and Integrity All-Ultrex became Essential. A quote or a website that still says Integrity is using the old name.

›Is Infinity the same as Marvin?

Infinity by Marvin is Marvin's replacement-only brand, launched in 2002 and renamed from Infinity from Marvin in 2025. It uses Marvin's Ultrex fiberglass but has its own warranty and its own sales channel: independent Infinity retailers, plus Infinity Replacement by Marvin, a company-owned division that reached its 19th market in May 2026.

›What's the difference between Infinity and Marvin Essential?

Both are Ultrex fiberglass windows. The differences are how you buy them and the warranty. Essential is sold by Marvin dealers with Marvin's transferable warranty (10 years on non-glass parts, 20 years on the glass seal, no labor). Infinity carries a lifetime warranty on the frame and non-glass parts for the original owner who lives in the home, if it's registered within 60 days, and Infinity Replacement locations add a 5-year installation warranty.

›Does the Marvin warranty cover installation?

No. Marvin's 2026 warranty states that removal, installation, finishing, refinishing and disposal costs are not included, and Marvin says installation is warranted separately by the installer. Infinity Replacement locations give a 5-year installation warranty; independent Infinity retailers and Marvin dealers set their own terms.

›Is the Marvin warranty transferable?

The warranty on Marvin's five collections is fully transferable, with every term counted from the original purchase date. Infinity's lifetime coverage is not: it lasts while the original purchaser owns and lives in the home, and a later owner gets the 10/20 terms (10 years on non-glass parts, 20 years on the glass).
