Please Note: Newport Design covers installation only - there is no warranty on the material itself. Our warranty extends one year and covers any seams you may have. Avoid putting excess weight or pressure around your sink or cooktop, this may  result in a crack which will not be under warranty. Always use a ladder or step-stool to clean windows or change light bulbs. The granite countertops you receive from Newport Design will be sealed at the time of installation. We recommend they be resealed every six months. This is an easy application - just apply the sealer on a clean cloth and apply  evenly on your countertops. Allow the sealer to penetrate, then remove any haze if necessary. There are also everyday stone cleaners that can  be used to help maintain the surface's shine. This attention to your  countertops will keep them looking beautiful for years to come, allowing you to truly appreciate them. A sincere thank you from Newport Design for selecting us for your stone needs.
