Migliaccio & Rathod LLP is investigating Cosentino S.A. for quality and safety defects in its “Silestone” quartz countertops.
Reported Silestone Issues
Users have reported a persistent chemical odor from newly installed slabs, premature chipping, and surface scratching despite marketing that claims the product is “harder than granite.” Reddit threads indicate growing consumer concern and potential class-action discussions.
Why Consumers Should Be Concerned
The odor suggests off-gassing of resin binders, posing potential indoor-air-quality risks. Consumers may also face repair costs and property-value losses from the chipping and scratching of a product advertised as “maintenance-free.”
Signs You May Be Affected
- Purchased or installed Silestone between 2023–25.
- Experienced lingering sweet or chemical odors or unexpected chipping.
- Selected “low-silica” slabs expecting safer materials.
