Sungloss Marble Co. does a great job for us! They clean and seal the floors, the elevators, and the walls, which are marble about one fourth of the way up. Their employees are professional people, and they interact well with us. They listen to what we tell them, and they pay attention to details. Like I said before, they do a great job for us, and we highly recommend them to everyone! They know what they are doing when it comes to taking care of marble and stone surfaces!
