DuPont™ Corian Quartz® Residential Ten-Year Limited Warranty for North America

DuPont warrants to you, the owner of the original installation of DuPont™ Corian Quartz® quartz surfaces in your residence, that upon the following terms and conditions DuPont will, at its sole option, repair or replace, without charge, your installation of DuPont Corian Quartz® when installed by a DuPont Authorized Corian Quartz® Installer, provided that DuPont or its authorized warranty service agent determines that the product has failed due to any manufacturing defect or any defect in conversion or installation that is covered by this limited warranty during the first ten (10) years from the date of completion of installation of the Corian Quartz®.

General Terms and Conditions

The following contains information applicable to this limited warranty:

  1. This warranty applies to DuPont™ Corian Quartz® quartz surfaces only, and does not apply to any other products, including engineered stone products, manufactured or supplied by any other party, except by DuPont.
  2. This warranty applies to installations of Corian Quartz® quartz surfaces that have been permanently installed in the interior of residences for countertop usage and that have not been moved from the original, permanent installation. This warranty does not apply to other installations of Corian Quartz® such as, but not limited to installations in shower walls, boats or recreational vehicles, or outdoor uses. If after, or during installation, you decide that you do not like the color you selected, replacement is not covered by this warranty.
  3. This warranty applies to product purchased and installed after March 31, 2006, for owner-occupied residences.
  4. To obtain service under this limited warranty, you must contact the source from whom you purchased DuPont™ Corian Quartz®, or DuPont at the address shown at the end of this limited warranty. To qualify for repair or replacement, you must provide the original sales receipt or other documentation acceptable to DuPont that demonstrates proof of purchase clearly showing the date of purchase, the date the installation was performed, and that such installation was performed by a DuPont Authorized Corian Quartz® Installer. Your proof of purchase must identify your installation as DuPont™ Corian Quartz®. If you represent to us that your installation is DuPont™ Corian Quartz® and upon arrival of our warranty service agent at the installation site, we determine that your installation is not DuPont™ Corian Quartz®, you will be liable for and charged the standard warranty service trip charge in effect at that time and no repair or replacement will be performed. You must permit DuPont or DuPont’s authorized agents to inspect the installation of the product. You will reasonably cooperate with DuPont in DuPont’s efforts to perform its obligations under this warranty. All decisions about defects in manufacture, conversion or installation shall be made by DuPont and communicated to you in a timely manner. Whether DuPont performs repair or replacement of your installation, we will seek to obtain the best possible result, but exact color match cannot be guaranteed.
  5. This warranty shall be null and void unless the products and the installation have been paid for in full.
  6. What You Should Expect From the Appearance of Your DuPont™ Corian Quartz®:Color Variation Within an Installation: Since DuPont™ Corian Quartz® is made from natural quartz, variations in the color, size, shape and pattern of distribution of the natural stone (quartz), and the tone of the background, are inherent and unique characteristics to be expected with this product. If the natural variation is visible in an installation from a distance of 7 feet or greater with uniform lighting (no spot lights or high intensity lighting) it will be considered to be a material defect and covered by this warranty, but you must report it within ninety (90) days of installation. If the color variation is not visible from 7 feet or if it is not reported within ninety (90) days of installation, it will be considered to be a normal variation and not covered by this warranty.Color Samples: Samples are only representative and are not an exact replication of what will be installed in your home. Variations in the color, gloss, finish, size, shape and pattern of distribution of natural stone (quartz), and the tone of the background, are inherent and unique characteristics to be expected with this product. This does not affect the product performance in any manner. Your countertop will not be replaced under this warranty due to these variations.Blemishes: Some level of what could be referred to as spots or blotches are inherent in the manufacturing process. Blemishes larger than the size of a US twenty-five cent piece are covered under this warranty. In the rare case where a foreign particle (such as a piece of rubber, metal or wood) is found in the product, then it is covered by this warranty.

    Gloss: DuPont™ Corian Quartz® measures an average of 40 gloss units or greater, as measured at 60 degrees with a gloss meter. P erfect light reflection would measure 100 and by contrast granite typically measures 70 to 85, so Corian Quartz® should be expected to have less gloss than granite. An installation with average gloss that measures 40 or more is standard product and not covered by this warranty. Gloss levels can generally be increased by cleaning the installation as identified in this warranty document or on our website.

  7. This warranty is transferable within the 10-year period of warranty only when the new owner writes to DuPont (see address at the end of this limited warranty) to register the installation under the new owner’s name. The new owner may also refer to our website, shown below, which details the proper maintenance of the product.
  8. This warranty applies to products that have been maintained according to the DuPont™ Corian Quartz® quartz surfaces Care in Use Guide provided free of charge at the time of installation, upon request, from the DuPont Authorized Corian Quartz® Installer or from DuPont, or on our website shown below.
  9. This warranty covers seam performance, not the appearance of the seam which means that seams may be noticeable to the eye or may feel unaligned by touch. Furthermore, placement of the seams is at the discretion of the fabricator/installer, using color coordinated seam adhesive. Seam failure due to settling or structural issues unrelated to the countertop installation are not covered by this warranty.
  10. This warranty does not cover uses of products for “commercial” uses, uses of products exposed to outside weather and climate conditions, abnormal use or conditions, or abuse in any way. “Commercial use” includes, but is not limited to, use in a store, office or other place of business. “Abnormal use or conditions” includes, but is not limited to, damage from mishandling or misuse, damage from excessive heat or uneven exposure to weather conditions, physical or chemical abuse, and damage from improper care and maintenance. Improper care of DuPont™ Corian Quartz® may result in staining scratching, chips in the surface, cracking or seam separation.Cracking or Seam Separation:Once installed the two primary causes of cracking and seam separation are (i) shifting or movement of the substrate, cabinets or foundation; and (ii) thermal shock, which can occur when a hot pot, pan, dish or any other receptacle or object is left on the countertop for more than a brief period. Trivets or hot pads should always be used. The foregoing are not considered to be material defects, but rather, subject to proper care and maintenance by you.Chips: Chips are caused by impact. The quartz and polyester are bonded together using pressure and vacuum. Chips or any other impact damage are not covered under this warranty.Scratches: DuPont™ Corian Quartz® is extremely scratch resistant, however, it can be scratched when proper care is not used, and accordingly, scratches in your Corian Quartz® installation are not covered by this warranty. Cutting boards should always be used as part of your proper care and maintenance.

    Staining: DuPont™ Corian Quartz® is stain-resistant, but not stain proof. Stains can usually be removed with chemical cleaners. Staining is not covered by this warranty. You can view our stain cleaning guidelines on our website shown at the end of this document or at the phone number also shown at the end of this document.

  11. DuPont is not responsible for damage or injury caused in whole or in part by acts of God, job site conditions, architectural and engineering design, structural movement or settling, acts of vandalism, or accidents.
  12. DuPont’s obligation under this warranty is limited solely to the repair or replacement of the DuPont™ Corian Quartz® product covered by this warranty, including necessary labor charges needed to repair, remove or replace the product. DuPont will repair or replace any area of the installation that is determined by DuPont or its warranty service agent to be defective. To the extent required, DuPont will cover the cost of the simple plumbing and electrical disconnect and reconnect charges to the extent determined necessary by DuPont or its warranty service agent. You will be responsible for any other costs associated with or arising out of the repair or replacement, such as, but not limited to, repairs to wall surfaces, paint, wall paper, tiles, and removal of cabinets, storage bins and food garages or backsplashes to allow access to the Corian Quartz® product for repair or replacement, as well as costs incurred to enable access to plumbing and electrical connections. Your original warranty will continue for the duration of the original ten year period and not from the date of any repair or installation.
  13. Except as provided in this limited warranty, DuPont shall not be liable in either tort or contract for any loss of direct, consequential or incidental damages arising out of the use or inability to use the product in residential applications covered by this warranty. Some states do not allow the exclusion or limitation of incidental damages, so the above limitation or exclusion may not apply to you.
  14. DuPont makes no other warranty, representation or guarantee, express or implied, with respect to its products, except as expressly stated herein. Some states do not allow limitations on how long an implied warranty lasts, so the above limitation may not apply to you.
  15. This warranty gives you specific legal rights, and you may also have other rights which may vary from state to state or, in Canada, from province to province.This is the only warranty made by DuPont for Corian Quartz® quartz surfaces. No representative, dealer, sales person or any other person is authorized to make or makes any warranty or promise on behalf of DuPont with respect to Corian Quartz® quartz surfaces. No terms or conditions other than those stated herein or provided by law, and no agreement or understanding, oral or written, in any way purporting to modify this warranty shall be binding upon DuPont unless made in writing and signed by an authorized employee of DuPont.
