I purchased a Big Deal for Stone Masters. The Big Deal was for $149 for cleaning, hand polishing, and sealing of natural stone countertops. They polished and sealed my granite kitchen countertops. They came out within the week or some weeks maybe after I purchased the Big Deal. My countertops looked beautiful after they were polished. They did a fantastic job for me. There were no additional charges to the $149 Big Deal. I think the tech was very good and knowledgeable. I appreciated the extra effort. I would refer them to someone.
