We had just installed a new kitchen with a beautiful quartz countertop. Right after it was installed, during the backsplash installation, a tool dropped and made a pit hole in the counter and a small dent out of the edge. I went right back to where we got the counter top and they recommended the Stonedoctor and gave me Peter's name and recommended the company. Couldn't get to it right away, however, I then accidentally, took a bit of the island countertop edge off. 3 very minute spots, but bothersome. Right then and there emailed peter- unfortunately he wasn't available so sent me to his colleague Vadim. Vadim came and repaired all 3- he was very nice, skilled and I was amazed by his work. Was so prepared, tidy, cleaned up and was overall so pleasant. He even guaranteed his work. Overall, pricey for the very minuscule size, but understandable for the steps it takes to fix. My husband and I were so pleased- you can't tell anything ever happened. Highly recommend these guys!
