Andersen vs Milgard Windows: Price, Materials & Warranty Compared (2026)

Andersen and Milgard are often compared on Milgard's famous lifetime warranty. That warranty is real, but since July 1, 2024 Milgard has issued two different warranties. Its full lifetime parts-and-labor coverage applies to some series only, for the original owner, in homes inside Milgard's service territory. That detail matters more than anything else on this page.

On price, only one brand can be checked before a quote. Andersen's 100, 200 and 400 Series are sold at Home Depot, where our September 2026 census found shelf medians of $358–$854 per window, unit only. Milgard sells through dealers and publishes no price. Start with the window replacement cost calculator for a project-level estimate.

How this estimate is calculated

$509–$1,600 per window installed, from BLS wages and the FRED price index

Based on BLS, FRED & EIA data

Labor, weatherproofing and price escalation come from federal data. The base material cost does not — and we say so below rather than rounding it into the same sentence. Reference window: standard vinyl double-hung, retrofit install.

Labor: 2 man-hrs (NREL/Craftsman) × $29/hr national carpenter wage (BLS OEWS, SOC 47-2031) × 2.84 contractor markup = $165
Materials: Vinyl frame + Low-E glass, escalated 4.9% since 2025 by the FRED producer price index. The base cost this escalates is not independently sourced — it is the largest single term in the estimate and the one we cannot yet cite. Retail listings for the products named in our tiers put a comparable unit at $284–$379, which brackets it. How we are trying to close that.
Weatherproofing: $20–$35 per opening — flashing tape, foam, backer rod and caulk, priced per opening rather than as a percentage of the window (DuPont GREAT STUFF)
Installed cost: $509–$1,600 per window installed — the low end is buying the window and hiring an installer, the high end is a full-service replacement company. Both are installed prices; they are different markets, roughly 2× apart. · $5,090–$16,000 for a 10-window project (before bulk discount)

Andersen vs Milgard: What Each Publishes on Price

Andersen figures are retail shelf prices at Home Depot for the window alone. Installation is extra, and our cost model puts it at $185 to $200 per opening for a double-hung insert. Our census also searched for Milgard Trinsic and Tuscany windows and found no big-box listing it could price.

Line	Frame	Price per window
Andersen 100 Series	Fibrex composite	Shelf medians: $483 single-hung, $465 slider, $854 casement
Andersen 200 Series	Wood, vinyl Perma-Shield exterior	Shelf $399 (1 listing)
Andersen 400 Series	Wood, vinyl Perma-Shield exterior	Shelf medians: $717 double-hung, $588 casement, $358 awning
Milgard V250 Style Line / V300 Trinsic / V400 Tuscany / V450	Vinyl	Not published — priced by dealer quote
Milgard C650 Ultra / C700	Fiberglass	Not published — priced by dealer quote

“Shelf” is the retail price of the window alone at Home Depot or Lowe’s — not installed — from our Google Shopping census, checked 2026-09-08. Where no company publishes a price we say so rather than estimate one.

A shelf price is a standard-size unit with no labor, trim or disposal. The fair comparison is an installed Andersen quote against a Milgard dealer quote for the same openings. Our installation labor cost guide shows what the labor line should look like.

The Two Lineups

	Andersen	Milgard
Vinyl	Not in the 100, 200, 400 or A-Series; 200 and 400 use vinyl only as cladding over wood	V250 Style Line, V300 Trinsic, V400 Tuscany, V450
Fiberglass	A-Series: fiberglass exterior, wood interior	C650 Ultra, C700
Composite	100 Series: Fibrex inside and out	None
Wood interior	200 Series, 400 Series, A-Series	Not a listed window series material
Aluminum	None in the series above	A250 Thermally Improved Aluminum

Andersen positions the 100 Series as “the smart alternative to vinyl” and the 400 Series as its best seller. Its wood core is protected by Perma-Shield, which Andersen describes as “a proprietary, high-grade vinyl that we vacuum form or extrude around the wood.” Milgard calls V400 Tuscany “top-of-the-line vinyl windows,” says the V250 Style Line pairs quality with affordability, and calls C650 Ultra “exceptionally strong and low-maintenance.” The C700 is Milgard's newest fiberglass series.

For a wood interior, Andersen is the only choice of the two. For an all-vinyl window, Milgard is.

Warranty: Read Which Milgard Warranty You Get

Milgard covers windows sold after July 1, 2024 under one of two documents, depending on the series:

	Milgard Full Lifetime	Milgard Lifetime Limited	Andersen 400 Series
Series	V400 Tuscany, V300 Trinsic; V450 and V250 only if upgraded at purchase	C650 Ultra, V450, V250 Style Line, A250	400 Series
Original owner, inside service territory	Parts and labor, for as long as you own and live in the home	Frame: parts for life. Glass unit and components: parts for 20 years. Skilled labor: 10 years	20 years standard glass, 10 years non-glass
Original owner, outside service territory	Parts only, for life	Same parts terms; owner pays all labor and shipping	Same as above
Later owners	10 years, parts only	10 years, parts only	Transferable (Owner-to-Owner)
Glass breakage	Tuscany and V450 included; Trinsic with upgrade	Excluded	See series warranty

“Service Territory” is defined by Milgard at milgard.com/serviceterritory. Labor coverage depends on whether your home was inside it “at the time of Product purchase.”
The C700 is not named in either July 2024 document. Ask the dealer which warranty applies and get it in writing.
Some coverage is shorter on both Milgard warranties: 10 years on painted and fiberglass frame finishes, and one year on weatherstripping, insect screens and stress cracks.

Which Should You Choose?

Choose Andersen if:

You want a wood interior. Milgard's window series list no wood.
You want to see a price first. Andersen's retail lines are priced on the shelf at Home Depot.
You may sell within a few years. A Milgard warranty drops to 10 years of parts for the next owner.

Choose Milgard if:

You are inside Milgard's service territory and plan to stay. That is where a Tuscany or Trinsic window's lifetime parts-and-labor coverage applies.
You want all-vinyl or all-fiberglass frames. Milgard offers four vinyl series and two fiberglass series.

Frequently Asked Questions

Is Milgard better than Andersen?

They lead with different materials. Milgard's lineup is mostly vinyl (V250 Style Line, V300 Trinsic, V400 Tuscany, V450) plus two fiberglass series (C650 Ultra and C700). Andersen's retail lines are Fibrex composite (100 Series) or wood clad in vinyl (200 and 400 Series). The biggest practical difference is the warranty: Milgard's best coverage includes parts and labor for life, but only on certain series and only for an original owner inside Milgard's service territory.

Does Milgard's lifetime warranty really include labor?

Only in one case. Under Milgard's Full Lifetime Warranty (V400 Tuscany and V300 Trinsic, or V450 and V250 with the upgrade bought at the time of sale), Milgard provides parts and labor for as long as the original owner owns and lives in the home, if the home is inside Milgard's Service Territory. Outside the territory it is parts only. On the Lifetime Limited Warranty (C650 Ultra, standard V450 and V250, A250), Milgard pays for skilled labor only within 10 years and only inside the territory.

What happens to the Milgard warranty when I sell my house?

It shrinks. Under both 2024 Milgard warranties, a subsequent owner gets 10 years of parts coverage from the date of manufacture, not lifetime coverage. Andersen's Owner-to-Owner limited warranty is transferable.

Is Milgard more expensive than Andersen?

Milgard publishes no prices, and our September 2026 census of Google Shopping found no Milgard Trinsic or Tuscany listing at a big-box store that it could price. Andersen's retail lines could be priced: shelf medians of $358–$854 per window, unit only, at Home Depot. A Milgard price comes from a dealer quote. Compare it against an installed Andersen quote for the same openings.

Is Milgard only available in the West?

Milgard's website asks for your ZIP code because "products and options vary by location," and tells some visitors that Milgard products and services are not available in their ZIP code. Its warranty also turns on whether your home is inside its Service Territory, published at milgard.com/serviceterritory. Check both before you plan around a Milgard window.

Fiberglass or Fibrex: what is the difference?

Milgard's C650 Ultra and C700 series are fiberglass. Andersen's Fibrex, used in the 100 Series, is a composite of wood fiber and thermoplastic polymer that Andersen calls 2x stronger than vinyl. They are different materials, and neither maker publishes a head-to-head test.
