As a property manager, I always use Sungloss Marble Co. We highly recommend using them. We are on a service contract with them where they come out to do maintenance cleanup in Spring and Fall. I know that my company has used them for many years prior to my coming onboard four years ago. It is most convenient that Sungloss Marble Co. calls us with reminders when it is time to have them come out again. The technicians are very corrective and do a great job with maintaining areas in our building that have very heavy traffic flow, from our lobby--all the way up to our penthouse.
