I am a property manager, and I have used Sungloss Marble Co for over eight years. That means that I have used them a lot of times. They do an excellent job for me each time. Their employees are punctual, friendly and professional. They are also very compliant with all COVID-19 protocols. The company has a wide range of services that they provide, from tile and stone cleaning to graffiti removal. For example, this building has a very porous stone external surface, and when the graffiti artists strike, the paint seeps down into the stone. Sungloss Marble Co. has the answer. They apply clay to the surface, and the clay sucks the paint back out of the stone. They taught me a new trick with this one! It was just like watching magic, the way they did that! I can not recommend Sungloss Marble Co. highly enough! They know what they are doing when it comes to cleaning stone or hard surfaces!
