I remodeled kitchen had new cabinets and countertops put in. Silestone Helix Counter top was installed in February of 2019. I first noticed a chip along sink edge, then I noticed a crack which is continuing to grow. I contacted Lowes's they sent out an inspector who says this is the 2nd one in 1 week that he was called to and wondered if it was manufacture defect. Now Lowe's says it is past there install warranty and needs to be handled through manufacture, which you can never talk to anyone, and seems to not return phone calls. I am in the process of filling a class action against Consentino because we spent several thousand dollars for these counter tops. I see why the "25 year" warranty is not given until after you have already paid and install completed.
