Specialist cleaning of Monuments including Grade1 listed buildings (Cathedrals, Churches, Stately homes and Palaces) takes a great deal of thought and care to prevent lasting damage. We partner with the stone experts who developed the Thermatech cleaning systems. Their knowledge is exemplary and together we work with your conservation teams or architects and create a method statement on the best course of action. Naturally, this will involve carrying out extensive tests beforehand.
