Questions about warranties for PVC windows and blinds

Warranties for PVC windows and blinds: basic rules

A warranty is a written obligation by the manufacturer or installer to repair or replace defects within a specified period. For PVC windows and blinds, warranties can cover materials (profiles, insulated glass units, fittings, blinds components) and installation work — if stated in the contract.

What warranties usually cover

  • Profile and welds: profile defects and geometry issues.
  • Insulated glass units (IGUs): seal failure and internal fogging (depending on the manufacturer period).
  • Hardware: opening mechanisms, hinges, handles, locks.
  • Seals and gaskets: cracking, loss of elasticity, deformation.
  • Blinds and roller shades: mechanism failure, guide damage, bent slats depending on type.
  • Installation: water infiltration, poor sealing, incorrect fastening — only if a mounting warranty is provided.

Typical warranty periods (approximate)

  • Profile: 5–10 years (varies by brand).
  • IGUs: 5–7 years (sometimes up to 10 for premium glass).
  • Hardware: 2–5 years.
  • Seals: 2–5 years.
  • Blinds and shades: 2–5 years depending on type (roller, Roman, vertical).
  • Installation: 2–5 years (if included in the contract).

Always check the exact terms in your purchase contract and product passport.

Who is responsible: manufacturer or installer?

  • The manufacturer typically warranties materials (profile, IGU, hardware).
  • The installer guarantees the installation workmanship.
  • Sellers may offer combined warranty coverage: some defects handled directly by them, others forwarded to the manufacturer’s service.

What voids the warranty

  • Unauthorized modifications: drilling, adding attachments, or aftermarket alterations without agreement.
  • Mechanical damage from impacts or improper use.
  • Incorrect maintenance: using aggressive chemicals or solvents.
  • Natural wear and tear over time if excluded in warranty terms.
  • Improper storage or transport by the customer.

How to accept the work and file a warranty claim

  1. Inspect windows/blinds immediately after installation with the installer present.
  2. Test hardware, closing tightness, absence of drafts, and seals condition.
  3. Record defects in writing: handover act, and take photos/videos.
  4. Keep documents: contract, payment receipt, product passport, warranty card.
  5. Submit a written claim to the seller or installer with evidence.
  6. Expect a service visit within the response time specified in the contract (commonly 7–30 days).

Warranty process: timing and repair

  • The seller or manufacturer should respond within the contractual period.
  • If a defect significantly affects use, a component replacement (e.g., IGU) or full replacement may be performed.
  • If repair is impossible in a reasonable time, the buyer may request replacement or refund according to contract and consumer law.

Practical tips to keep warranty valid and extend product life

  • Follow maintenance instructions: soft cloth, neutral detergents, lubricate hardware 1–2 times a year.
  • Do not overload sashes or use windows as supports for heavy objects.
  • Replace worn seals promptly via authorised service.
  • Register the product (if the manufacturer offers registration) to speed up service.
  • Consider buying extended warranty or a service contract from the seller for broader coverage.

Frequently Asked Questions (FAQ)

  • The IGU fogged after one year. What should I do?

    This indicates seal failure. Save photos and the installation act, submit a warranty request — IGU replacement is usually covered.

  • Can I replace the gasket myself?

    DIY replacements may be considered unauthorized intervention and could void parts of the warranty. Use authorised service.

  • Are scratches on the profile covered?

    Typically not — scratches from mechanical impact are excluded from warranty coverage.

  • What if the seller ignores my warranty claim?

    Send a written complaint with confirmation of delivery. If there’s no reaction, contact consumer protection authorities.

  • What is the warranty on installation?

    Usually 2–5 years; check your contract for exact terms.

  • Can I extend the warranty?

    Many companies offer paid extended warranties or maintenance contracts.

  • Who pays for a technician’s visit under warranty?

    Normally the seller/manufacturer covers service visits under warranty. Paid visits may apply for out-of-warranty requests.

  • How long does warranty repair take?

    Depends on complexity: hardware replacement — 1–7 days; IGU replacement — 7–30 days (including production time).
