Maybe you can help me too. I have been trying to contact Mark Growberry with SileStone in Atlanta. We installed our countertops 6 years ago and had no problem, until December I found a small 1" crack next to the sink and the cook top. I called my Kitchen Cabinet company who contracted silestone to install our countertops. That was January. Since then I have been getting the runaround. Today finally an installer from SileStone came in and told me that the crack was cause from tempertature change. This answer is not acceptable to me. I called Mark again and he had my secretary call me back. She was unable to explain the decision. I asked her to ask Mark to call me and left him another message. I have yet to hear from him.
