We purchased a Silestone quartz surface countertop in 2002 with a ten year warranty. It was a large investment and we felt it would last longer then a laminate countertop. However, we found a defect in the stone (chip) within six months and now we have two cracks and a seam that is easily noted.
The installer said not to worry about the initial chip in the countertop and said we had the ten year warranty to do anything about it. The choice I had was to drill a hole into the countertop and replace the area where the chip is in the countertop and I was afraid it would look worse then it does now.
We contacted Home Valu in the summer of 2007 and they sent out the installers who actually sent the pictures and description of the cracks to the Silestone warranty department. In September 2007, we received a letter from Oscar Jimenez, General Manager, stating the cause of the cracks was due to "settlement of your home" and would not be covered under the Silestone Limited Warranty. Our house was fifteen years old when the countertop was installed and this would not be an issue. I question if I would put this product in a new home since homes do settle in the first year. We have placed no heated objects on our countertop, however, one crack is close to the dishwasher.
I have been in contact with Home Valu, where we purchased the countertop, and they contacted Silestone also. Home Valu manager said a Silestone representative was to call and set up at time to look at the Silestone countertop in our home, however, we've never heard from them (September 2007). I have my third call to Home Valu to inquire why we have not heard from Silestone.
Silestone is an expensive product and in my opinion, Silestone is not living up to their warranty. Unless they change and honor their warranty, I would not purchase this product. I would also be concern placing this product into a new home due to the Limited Warranty which Mr. Jimenez stated would not cover "cracks due to structural movement, settlement of your home, building etc.
