Does Refinishing Quartz Countertops Void the Warranty?
By Fred Hueston
Quartz countertops have gained immense popularity due to their durability, low maintenance, and stylish appearance. However, with daily use, they can develop minor scratches, dull spots, or other cosmetic imperfections. As a professional stone and tile restoration contractor, you may be asked if refinishing or polishing a quartz countertop voids the manufacturer’s warranty. Let’s dive into this important topic so you can better guide your clients.
Understanding Quartz Countertop Warranties
Most quartz manufacturers provide a limited warranty that covers material defects and, in some cases, workmanship during the fabrication and installation process. These warranties typically last between 10 years and a lifetime, depending on the brand. However, it is important to note that warranties usually include several exclusions. These can vary, but some common exclusions include:
- Damage caused by misuse or negligence
- Heat damage or burns
- Stains and chemical damage
- Unauthorized repairs, refinishing, or modifications
One key element to emphasize is that any modification to the surface, such as grinding, honing, or polishing, is generally not covered under the warranty. This means that once you perform any significant refinishing work, the warranty could be voided.
Why Refinishing May Void the Warranty
Refinishing involves removing a small layer of the quartz surface, which manufacturers often view as altering the original product. Quartz countertops consist of a mix of natural quartz crystals and resin binders. The surface finish created during the manufacturing process is achieved using precise techniques and machinery that are difficult to replicate during field refinishing. Manufacturers claim that once the factory finish is altered, the surface no longer meets their specifications, which can lead to:
- Inconsistent Surface Sheen: Field polishing may not achieve the same level of uniformity as the factory finish.
- Weakening of Resin: Aggressive refinishing may compromise the resin, leading to more susceptibility to future damage.
- Potential Discoloration: Overheating the surface during polishing may cause the resin to discolor or “burn.” This is especially common with darker-colored quartz.
Because of these factors, most manufacturers include specific language in their warranties indicating that any unauthorized refinishing voids the coverage.
Communicating with the Client
Before starting any refinishing or polishing work on a quartz countertop, it’s critical to have an honest conversation with your client. Here are some key points to cover:
- Check the Warranty: Encourage the client to review their warranty terms and contact the manufacturer if necessary to clarify any exclusions.
- Written Agreement: Obtain written consent from the client acknowledging that the refinishing process may void the warranty.
- Outline Expectations: Explain the potential risks and set realistic expectations regarding the appearance after refinishing.
When Refinishing May Be Worth It
In some cases, refinishing may still be the best option despite the potential warranty void:
- Out-of-Warranty Surfaces: If the countertop is past its warranty period, refinishing can extend its useful life.
- Minor Imperfections: Light polishing to remove minor scratches or dull spots can restore the surface without heavy modification.
- Cost of Replacement: In some situations, the cost of replacing the countertop may be prohibitive, making refinishing a cost-effective solution.
Best Practices for Refinishing Quartz Countertops
If you and your client decide to proceed with refinishing, follow these best practices to minimize risks:
- Use Low Heat Tools: Avoid excessive friction and heat buildup during polishing to prevent resin discoloration.
- Avoid Harsh Abrasives: Use fine-grit abrasives designed for quartz surfaces to avoid deep scratches.
- Test in an Inconspicuous Area: Perform a small test in an inconspicuous area to ensure the desired result can be achieved without unexpected issues.
- Use Specialized Polishing Pads: Consider using diamond-impregnated pads specifically made for engineered stone to achieve a better finish.
Refinishing and polishing quartz countertops can void the warranty, but this doesn’t always mean it’s the wrong decision. By clearly communicating the risks and rewards with your client, you can build trust and ensure they make an informed choice. Be sure to document your process, use the correct tools, and set proper expectations for the final appearance. In the end, a well-executed refinishing job can restore the beauty of the surface and extend the life of the countertop, even if it means operating outside of the manufacturer’s warranty guidelines.
