Stone Mart supplied the stone for my pool deck. As soon as tiles were installed they started chipping. Manufacturers rep visited my house and said that Stone Mart did not show installers how to prep the stone resulting in at least 20 tiles chipping and cracking. Manager Bob promised 3 months ago to work w/ installer to replace bad tiles and repair the deck Now 3 months later he doesn't return calls and my $70K pool is a mess. Don't trust this company, their word is no good.
