Understanding the Silestone 25-Year Warranty (What Does It Actually Cover?)

By Tudor Granite, Worktop Specialist | Updated: October 2025

A 25-year warranty sounds fantastic, but what does it mean in practice? The warranty is a key benefit we highlight in our main Silestone article. Here, we explain exactly what is and isn't covered, so you know what to expect.

What IS Covered?

The Silestone warranty covers manufacturing defects in the material. This means if there is a flaw that came from the factory, it is covered. Examples could include:

• A slab that has inconsistent colouring that is not part of the design.
• Unusual pitting or blemishes that are not a natural feature of the material.
• A failure of the material under normal use that is not caused by an external factor.

What IS NOT Covered?

This is the most important part to understand. The warranty does not cover damage caused by external factors or improper use. This includes:

• Chips and Scratches: These are considered wear and tear from use.
• Heat Damage: Damage from placing extremely hot pans directly on the surface is not covered.
• Stains: While Silestone is highly stain-resistant, the warranty does not cover stains caused by neglect or use of improper chemicals.
• Damage from improper installation: This is why it's vital to use an approved fabricator and installer like Tudor Granite. Our workmanship is guaranteed separately.

How to Activate Your Warranty

After your installation is complete, you must register your product on the Silestone website within 6 months. We provide all the necessary details for you to do this.

Conclusion

The Silestone warranty is a powerful assurance of the material's quality. It gives you peace of mind that you have invested in a product free from manufacturing flaws. For protection against everyday accidents, proper care and attention are still essential.
