Warranty Terms & Conditions

Why the KINGSTONE Quartz Warranty Matters

Choosing the KINGSTONE Quartz Collection means more than selecting premium quartz surfaces — it means investing with confidence. Our warranty is crafted to protect your purchase while emphasising responsible care and use. The warranty is transferable in certain cases, offering added value for homeowners.

With coverage available for both residential and commercial applications (subject to the terms below), the stone collection provides unmatched assurance. From kitchens to office spaces, KINGSTONE Quartz ensures your surfaces remain elegant, functional, and protected under clear warranty terms.

At KINGSTONE Surface, we stand behind the strength, design, and innovation of our products. With the KINGSTONE Quartz Collection, customers gain not only luxury quartz surfaces but also the confidence of a warranty that truly supports their investment.

Terms and Conditions of KINGSTONE Quartz Collection

1. This warranty applies only to KINGSTONE's quartz surfacing materials and does not apply to any other products, including other quartz surfacing products manufactured or supplied by any other party.
2. This warranty applies only to KINGSTONE's quartz surfacing materials that have been permanently installed in the interior of single-family residences and have not been moved from their original installation. If after or during installation you decide that you do not like the colour or finish you selected, that decision is not covered under this warranty.
3. This warranty does not cover any residence where the owner is not the occupant.
4. This warranty does not cover materials and/or services that have not been paid in full.
5. This warranty applies only to materials that have been maintained according to the KINGSTONE Care & Maintenance guidelines. Care & Maintenance guidelines are available at our Maintenance & Care page.
6. Following installation, you must register your product within thirty (30) days in order to activate your warranty. Simply complete the online form available on our Warranty Registration page. You must agree to cooperate with KINGSTONE or its authorised agents in the inspection of the product and assist us in efforts to perform our obligations under this warranty.
7. In the event that KINGSTONE quartz surfacing materials fail due to a manufacturing defect, KINGSTONE will, at its sole discretion, repair or replace such materials. KINGSTONE will seek to obtain the best possible result, whether we decide to repair or replace your installation. However, an exact colour match is never guaranteed. All decisions regarding this warranty are at the sole discretion of KINGSTONE; no representative, dealer, salesperson, distributor, fabricator or any other person is authorised to make any warranty or promises on behalf of KINGSTONE with respect to KINGSTONE quartz surfacing products.

Exclusions

3. This warranty does not cover products used as flooring material.
4. This warranty does not cover improper use or abuse. Improper use or abuse includes, but is not limited to, damage from mishandling of the product, damage from excessive heat or uneven exposure to weather conditions, physical or chemical abuse and damage from improper care and maintenance.
5. This warranty does not cover chips or other excessive impact damage to the product.
6. This warranty does not cover scratches. KINGSTONE Quartz is a very hard material and highly scratch-resistant but not scratch-proof. Proper care must be exercised including the use of a cutting board as part of your care and maintenance.
7. This warranty does not cover routine maintenance. Routine maintenance includes but is not limited to minor conditions such as removing stains and water spots by following the techniques specified in our online Care & Maintenance guidelines.
8. This warranty does not cover failures due to fabricator or installer improper fabrication and/or installation; it is the sole responsibility of the fabricator and/or installer.

10. This warranty does not cover seam appearance or seam performance, adhesives, caulk or other accessory items. Once the product is installed, the two main reasons for seam separation or cracking are the shifting or movement of the substrate, cabinets or foundation, and thermal shock. Thermal shock can occur when a hot pan, dish or other object is left on the countertop for more than a brief period. Trivets or hot pads should always be used. These issues are not considered material defects and are subject to proper care and maintenance by the owner.
11. This warranty does not cover any chemical damage.

22. This warranty does not cover natural variations in the colour, size, shape, and distribution of the pattern of the natural quartz or the natural variations in background tone. These characteristics are inherent and unique to the product. Colour samples provided to consumers, dealers and fabricators are only representative and not an exact replication of what will be installed in your home.
23. This warranty does not cover what is referred to as spots or blemishes smaller than a UK ten (10) pence coin. A certain level of spots or blemishes are inherent in the manufacturing process and do not affect the structural integrity of the material.

Limitation of Liability

KINGSTONE is not responsible for damage or injury caused in whole or in part by job-site conditions, architectural / engineering design and structural movement, acts of vandalism, or accidents, which will void the warranty.

KINGSTONE shall not be responsible in either contract or tort for any loss of direct, indirect, consequential, incidental, special, exemplary, or punitive damages arising out of the use or the inability to use the products covered by this warranty.
