Silestone is one of the best-known quartz worktop brands in the UK, manufactured by Cosentino and available through major kitchen retailers including Howdens, Wickes and specialist stone suppliers. When a Silestone worktop chips or cracks, professional repair is usually possible — here’s what you need to know.
About Silestone Worktops
Silestone is an engineered stone product composed of approximately 94% quartz aggregate bound with polymer resins and pigments. It is available in a very wide range of colours — from bright whites and creams through greys, blacks, blues and naturalistic stone-effect patterns. The current Silestone range includes the Hybriq+ technology products, which blend quartz with other minerals.
Common Silestone Damage Types
- Edge chips — particularly on the exposed front and side edges
- Corner chips on breakfast bar overhangs
- Surface chips from dropped heavy objects
- Hairline cracks from thermal shock or point loading
Silestone Warranty and Repair
Silestone worktops come with a 25-year warranty from Cosentino. However, this warranty covers manufacturing defects — not accidental damage such as chips or cracks caused by impact or misuse. For accidental damage, professional independent repair is usually the most practical and cost-effective route.
Colour Matching Silestone
Silestone’s popular colours — Blanco Zeus, Cemento Spa, Altair, Iconic White — are well-known in the surface repair industry and we carry colour-matching compounds for the most common shades. Pattern-effect and veined Silestone colours require more blending but are still repairable to a very high standard.
