Replacement Window Warranty

Imperial’s limited warranty for our replacement windows includes the following coverage, subject to the applicable written terms and exclusions.

Window Hardware & PVC Extrusions

25-year coverage

25 years warranty on hardware parts and on PVC extrusions excluding labor and transportation caused by their replacement.

Insulated Window Glass

25-year coverage

25 years warranty on replacement sealed units. Qualifying seal failure may cause moisture or dirt to appear between the panes. This is different from condensation on the room-side or outdoor surface of the glass.

Window Paint & Coatings

15-year coverage

Painted or coated window surfaces are covered against peeling, cracking and excessive fading caused by manufacturing defects. After 15 years, qualifying replacement materials remain covered, but refinishing, replacement labour and service charges are the homeowner’s responsibility.

* Condensation on windows, which may occur as the natural result of inside temperatures, does not indicate a manufacturing defect and would not be included in this limited warranty.

Steel and Fiberglass Entry Door Warranty

Coverage varies by the panel, finish, frame, glass and hardware selected for your entry door. The main residential coverage periods are summarized below.

Steel Door Panels

20-year coverage

Steel panels are covered against qualifying warping, rust, cracking or buckling under normal residential use. Scratches, improper care and environmental damage are subject to the exclusions in the written warranty.

Fiberglass Door Panels

25-year coverage

Fiberglass panels are covered against qualifying defects in materials and workmanship, including delamination or structural failure. A multipoint lock is required for panel-warping coverage.

Door Paint & Stain

10 years paint · 5 years stain

Factory paint on steel and fiberglass panels is covered against qualifying blistering, peeling and uneven discoloration. Factory stain on fiberglass panels has five-year coverage; proper clear-coat maintenance is required.

Door Glass & Other Components

10-year residential glass coverage

Eligible glass units in a pre-hung entry-door system have coverage for qualifying seal failure and internal misting. Pressure cracks and glass breakage are excluded. Composite frames have limited lifetime coverage against qualifying defects, rot and decay. Eligible multipoint locks and accessories have their own coverage terms.

Keep your entry door properly maintained. Adding a storm door can void the entry-door product warranty. Contact Imperial before making changes to the door system. Labour and service coverage may be shorter than the product coverage; charges may apply after the applicable labour period.

Sliding Patio Door Warranty

Our sliding patio doors have separate coverage for the frame, finish, glass and operating components.

Vinyl Frames & Paint

25 years white PVC · 10 years painted PVC

White vinyl frame and panel components are covered against qualifying manufacturing defects. Factory-painted vinyl components have 10-year coverage against qualifying splitting, blistering, peeling, flaking, chipping or corrosion.

Insulated Patio Door Glass

20-year seal-failure coverage

Standard insulated sealed units are covered against qualifying dust, debris or condensation between the panes caused by seal failure. Surface condensation caused by excess indoor humidity is excluded.

Hardware & Internal Blinds

2 years hardware · 10 years blinds

Handles, security locks and rollers have two-year coverage against qualifying defects. Internal tilt-and-turn mini blinds have 10-year coverage for qualifying manufacturing defects, with 10-year seal coverage on the associated glass unit.

How to Request Warranty Service

Contact Imperial in writing promptly after discovering a problem. Window and entry-door warranty claims require written notice within 30 days of discovery. Keep your invoice and original warranty documents so we can identify the product and applicable coverage.

1. Send Your Details

Invoice & installation address

Provide your name, contact information, installation address, invoice number and purchase or delivery date. Tell us which window or door is affected.

2. Describe the Problem

Clear photos help

Include a brief description and photos of the complete product and the affected area. Leave the product in place and avoid unauthorized repairs or modifications before it is assessed.

3. Review the Next Steps

Inspection & service

We will confirm the next steps within two business days of receiving your notification. An inspection may be required to determine coverage. Inspection, labour or travel fees may apply to work outside the applicable warranty.

Selling your home? Imperial’s separate limited warranty may be transferred by the original property owner to one subsequent owner when Imperial receives notice within 30 days of the ownership transfer. Product-warranty transfer requirements vary; contact us with the original invoice to confirm what applies.

Proper window and door installation and ongoing care help protect product performance. Product warranties and Imperial’s separate obligations are distinct; parts coverage does not automatically include every labour, travel or refinishing cost.

Imperial’s separate limited warranty

IMPERIAL IS NOT RESPONSIBLE FOR:

The exclusions below apply to Imperial’s separate limited warranty. The entry-door glass and PVC lite-frame exclusion does not remove the window sealed-unit coverage stated above. Qualifying product-warranty coverage remains subject to its written terms.

  • * The limited warranty stipulated in this document is the only warranty applicable in whole, or in part, and is granted in lieu of any warranties written or oral other wise implied by law or equity and no such warranties shall apply to Imperial.
  • * Exposure to sunlight, air pollutants and normal atmosphere conditions may cause all material surfaces to gradually fade, chalk or suffer an accumulation of surface dirt or stains. These are normal occurrences and are not covered under Imperial Limited Warranty.
  • * No Warranty coverage if the sweeper is damaged due to ice buildup.
  • * Any defect, malfunction or failure to perform which has occurred because of unreasonable use or lack of necessary maintenance.
  • * Any damage to the window or components thereof, caused by settlement or structural defects of the building in which they are installed.
  • * Any damage caused by wind, hail, lightning or other acts of God, intentional acts, accidents, negligence or exposure to harmful chemicals or pollutants.
  • * Broken glass or torn screen as a result of any cause.
  • * Winly locks door’s hardware.
  • * Imperial provides no separate warranty on entry-door glass units’ failure and PVC lite frames beyond the applicable product warranty.
  • * Damage caused by improper handling or installation.
  • * Any Window which has been repaired, modified, or attempted to be repaired or modified by any person other than a duly authorized representative of Imperial.
  • ** Condensation or damages caused by condensation. Note: Unless the damage is relative to a breakage or defect of the insulated glass, most of the problems relating to the condensation are linked to the high, excessive humidity levels in the buildings. Contact a heating specialist to obtain help or advice.
