Silestone is the UK’s most popular quartz worktop brand — sold through kitchen retailers, stone merchants and independent kitchen designers across the country. When a Silestone worktop chips, professional on-site repair restores it precisely, without the weeks of disruption that come with worktop replacement.

About Silestone

Silestone is manufactured by Cosentino, a Spanish company and one of the world’s largest surface manufacturers. It is an engineered quartz — approximately 90% natural quartz particles bound with polymer resin — available in over 100 colours and designs across multiple collections.

Silestone’s consistent manufacturing quality and well-documented colour range make it one of the more straightforward premium quartz brands to repair accurately.

Common Silestone Damage

Corner chips — the most common. Front corners of worktops, particularly on kitchen islands, take significant daily impact.
Edge chips — along the front face of the worktop.
Sink cutout chips — where the worktop meets the sink aperture. Very common location.
Thermal damage — dull marks or surface crazing from sustained heat exposure. Hot pans placed directly on Silestone can damage the resin binder.

How Long Does Silestone Repair Last?

A professionally repaired Silestone chip lasts 8–12 years under normal conditions. Use pH-neutral stone cleaner (not bleach or acidic cleaners), avoid placing hot items directly on the surface, and the repair will outlast the cleaning cycle of a typical kitchen.

Frequently Asked Questions

Does Cosentino offer a repair service?
Cosentino does not carry out on-site repairs directly. They may refer you to local specialists. We are independent professionals who repair Silestone as part of our broader quartz repair service.
Will the repair affect my Silestone warranty?
Cosentino’s warranty covers manufacturing defects, not accidental damage. A chip is accidental damage and is not covered by the Silestone warranty regardless of who repairs it. Professional repair does not affect any remaining warranty coverage.
My Silestone is discontinued — can you still match it?
Usually yes. We work from the physical colour in front of us rather than relying on current product availability. Send photos and we will confirm.
