Pricing reviewed October 2026
Andersen and Pella are both full-range window makers, and their prices overlap heavily. Modernize puts Andersen at about $400 to $4,000 per window installed, depending on the series. Pella's own 2026 guide puts typical installed costs at $800 to $1,600 for vinyl and $1,100 to $2,200+ for fiberglass or wood (Pella; both as of Oct 27, 2026). The practical differences are materials and warranty structure. Andersen centers on Fibrex composite and clad wood with a transferable 20-year glass / 10-year parts warranty. Pella sells vinyl, fiberglass and wood, and gives original owners lifetime coverage on many components.
This comparison uses each manufacturer's published product and warranty documents, plus third-party cost data. We don't score or rank the brands, and there are no reviews or ratings here. For a general look at materials, see window cost by frame material.

Andersen terms are from its 400 Series Owner-to-Owner limited warranty for units made after Nov. 6, 2015. Andersen's warranty page lists separate warranty documents for its E-Series, A-Series, 400, 200 and 100 Series and Andersen Aluminum, and says its Owner-to-Owner limited warranties are transferable (Andersen). Terms for other series may differ. Pella's terms are from its warranty brochure, which it describes as correct as of 3/1/2024. Pella says current terms are at pella.com/warranty.

What really separates them
Materials
Andersen's distinctive material is Fibrex, a composite. Andersen describes its 100 Series as "twice as strong as vinyl" (Andersen). Pella offers true vinyl lines (150, 250, Encompass) and fiberglass (Impervia). If you want a pure vinyl or fiberglass window, Pella has it and Andersen's main series don't. If you want a wood interior, both have it: Andersen's 200, 400, A- and E-Series, and Pella's Lifestyle and Reserve.
Warranty structure
Andersen's 400 Series terms are simple and fixed: 20 years on glass and 10 years on other parts. They transfer intact to the next owner. Pella's vinyl terms favor the original owner, with lifetime coverage on frames and hardware operation while you own the home, but a later owner gets only the remainder of 10 years. Pella's fiberglass Impervia frame warranty is lifetime and nontransferable for the original owner. It switches to a transferable 10-year warranty when the home is sold (Pella Impervia warranty). If you expect to sell within about a decade, the two are closer than "lifetime" suggests.
Buying and installation
Both brands sell through retail and local dealers, so installation quality depends on who installs. Andersen also runs Renewal by Andersen, a full-service replacement business that handles design consultation and installation itself. It's a different buying experience, and Modernize's price range for it runs up to $4,000+ per window. We couldn't retrieve Renewal by Andersen's current warranty terms, so they're not compared here. Ask for the document with any quote.
Pros and cons
| Andersen | Pella |
|---|---|
| + Transferable 20-year glass / 10-year parts (400 Series) + Fibrex composite and a wide range of wood lines + Full-service option through Renewal by Andersen − Replacement-part remedy excludes labor (Andersen may instead repair at no cost) − Top series (A/E) run into the thousands per window | + Vinyl, fiberglass and wood under one brand + Lifetime coverage for original owners on many components + Two years of labor on service − Coverage drops to a 10-year remainder for later owners − Modernize lists dealer-to-dealer service variability as a con |
Pick Andersen if… / pick Pella if…
- Pick Andersen if you want Fibrex composite or a clad-wood window with warranty terms that transfer unchanged when you sell, or you want a single company to handle everything through Renewal by Andersen.
- Pick Pella if you want vinyl or fiberglass from a national brand, plan to stay in the home long-term so original-owner lifetime coverage pays off, or want to buy and compare at Lowe's.
- Coastal homes: Pella's Hurricane Shield and Defender lines are impact products. See our impact window cost guide for code and approval checks.
Who each brand fits
Andersen suits owners who want composite or wood and like fixed, transferable terms. Pella suits owners who want more material choice and plan to stay put. In both cases, the installer matters as much as the label. Get at least three written quotes and compare them with our quote checklist.

Frequently asked questions
Is Andersen or Pella more expensive?
Their ranges overlap. Modernize puts Andersen at about $400–$4,000 per window installed depending on series. Pella's own 2026 guide gives $800–$1,600 installed for vinyl and $1,100–$2,200+ for fiberglass or wood.
What is the Andersen 400 Series warranty?
Andersen's Owner-to-Owner limited warranty for 400 Series units made after Nov. 6, 2015 covers glass for 20 years and non-glass components for 10 years from purchase, and it transfers to later owners.
Is Pella's warranty transferable?
Partly. On Pella's vinyl lines, original owners get coverage for as long as they own the home, and later owners get the remainder of 10 years. Impervia's lifetime frame coverage is nontransferable and becomes a transferable 10-year warranty when the home is sold.
Does Andersen make vinyl windows?
Andersen's main series use Fibrex composite (100 Series), wood with cladding (200, 400, A- and E-Series) or aluminum. Pella sells true vinyl lines such as the 150, 250 and Encompass.
What is Renewal by Andersen?
Renewal by Andersen is Andersen Corporation's full-service window and door replacement division, founded in 1995. It handles design consultation and installation itself.
