Andersen Windows Warranty: Coverage, Claims and Transfers

New windows are one of the biggest-ticket upgrades a homeowner can buy, so the fine print matters as much as the frame. An andersen windows warranty is a written limited warranty that covers manufacturing defects in your windows and patio doors — but the length and terms change depending on which Andersen product line you own.

This guide lays out the real coverage: glass terms, parts terms, what’s excluded, how transfers work, and exactly how to file a claim.

Quick Answer: Andersen Windows Warranty at a Glance

Andersen windows carry a limited warranty: 20 years on glass and 10 years on non-glass parts for the 200 and 400 Series, with replacement parts supplied but labor not included. Renewal by Andersen replacement windows go further — 20 years on glass and Fibrex material, 10 years on components, and 2 years on professional installation, with labor included on valid claims.

The warranty is transferable to a new homeowner. Start claims through your dealer, the parts store at andersenwindows.com, or Renewal by Andersen’s service team.

Official Policy Verification & Source Check

How We Check This Policy: We read Andersen’s official limited warranty documents and product warranty pages — not dealer brochures or forum posts. Where Andersen publishes separate terms for its retail series and its Renewal by Andersen replacement division, we keep them clearly separated below.

What the Andersen Windows Warranty Covers by Product Line

The single most important thing to know is that “Andersen warranty” is not one warranty. Andersen sells windows through its standard retail and new-construction lines (100, 200, and 400 Series) and through Renewal by Andersen, its full-service replacement division. Each carries its own written limited warranty, and mixing them up is the most common source of disappointment at claim time.

For the 200 and 400 Series — Andersen’s most popular lines — the warranty is a 20/10 limited warranty: 20 years on glass, 10 years on non-glass components, measured from the date of manufacture or installation per your warranty document. Andersen’s own parts catalog lists “20 / 10 Years Limited” as the warranty specification on 200 Series sash components.

When a covered part fails, Andersen supplies the replacement part; labor to remove and install it is not included under these series warranties.

The 100 Series (Fibrex composite, Andersen’s value line) carries a 10-year limited warranty. Renewal by Andersen replacement windows carry the strongest package: limited warranties covering 20 years on standard glass and Fibrex material, 10 years on components, and 2 years on professional installation — with parts, labor, and installation services included for valid warranty claims.

What the 20-Year Glass Warranty Covers

The glass portion of the andersen windows warranty covers manufacturing and material defects in the insulating glass unit: seal failure that causes fogging or condensation between panes, stress cracks, and spontaneous glass breakage that traces to a defect rather than an impact.

If your double-pane window goes cloudy between the glass, that is the classic glass-warranty claim, and Andersen will supply a replacement sash or glass unit under the 20-year term.

What the 10-Year Parts Warranty Covers

Non-glass components are covered for 10 years against defects in materials and workmanship: frames, sashes, operating hardware (locks, cranks, balances), weatherstripping, and factory-applied finishes. The key word is defects — a balance that fails because of a manufacturing flaw is covered; one that fails because the window was never maintained is not.

What the Andersen Windows Warranty Does Not Cover

Exclusions decide more claims than coverage terms do:

• Excluded Labor on 200/400 Series claims. Andersen’s standard-series warranty supplies replacement parts with labor expressly not included. Budget for a glazier or handyman unless you can swap the part yourself.
• Excluded Accidental glass breakage. A baseball through the pane, a storm-thrown branch, or a mower-kicked rock is not a manufacturing defect and is not covered on most series.
• Excluded Improper installation. Windows must be installed per Andersen’s instructions. A leak caused by a bad install is the installer’s problem, not a warranty claim — one reason Renewal by Andersen’s 2-year installation warranty matters.
• Excluded Normal weathering. Fading, chalking, or minor color change from sun exposure over time is expected wear, not a defect.
• Excluded Misuse, neglect, and modifications. Painting over weep holes, drilling into frames, or using harsh chemicals voids coverage for the affected part.
• Excluded Non-Andersen components. Third-party grilles, films, or hardware added after purchase are not covered.

Andersen vs. Renewal by Andersen Warranty: Side by Side

Shopping both? Here’s the difference that matters:

Renewal by Andersen costs more up front precisely because it bundles the product, the installation, and the labor coverage into one accountable warranty. If you buy standard Andersen windows through a dealer or home center, vet the installer as carefully as the product — installation problems are the top reason warranty claims get denied.

Is the Andersen Windows Warranty Transferable?

Yes. Andersen’s limited warranties are transferable to a subsequent owner of the home, which is a genuine selling point when you list your house. Keep your original purchase documentation — invoices showing the product series, installation date, and dealer name — and pass copies to the buyer at closing so they can prove coverage.

Transfer terms and any reduced terms for second owners are spelled out in the warranty document for your series, so read that page before you advertise “lifetime coverage” in a listing.

How to File an Andersen Windows Warranty Claim

1. Identify your product. Find the series (100, 200, 400, A-Series, or Renewal by Andersen), the unit size, and the issue. A photo of the product label or etched glass code speeds everything up.
2. Document the defect. Take clear photos of fogged glass, failed seals, or broken hardware, and note when you first noticed it.
3. Go through your dealer first. If you bought through a dealer or builder, contact them — they handle warranty processing for their installations.
4. Use Andersen’s parts store. For replacement parts, the parts catalog at andersenwindows.com lets you match the exact sash or component by product line and size.
5. Renewal by Andersen owners: call your local Renewal by Andersen location’s service team directly — your installation warranty and labor coverage run through them.
6. Keep everything in writing. Save claim numbers, emails, and photos until the part arrives and the repair is complete.

If your claim is denied, ask for the denial reason in writing and compare it against your series’ warranty document — dealers occasionally misclassify a defect as an installation issue, and the written terms are what count.

FAQs

Conclusion

The andersen windows warranty is a solid, clearly written limited warranty — 20 years on glass and 10 years on parts for the mainstream series — with the main catch being that standard-series claims cover parts, not labor. Know your series, keep your paperwork, and route installation issues to the right party. For the official warranty documents and to start a claim, visit andersenwindows.com.
