The cleaning of masonry facades, whatever the material, is the most visible aspect of building conservation work. At Sun India Services Private Limited, the building’s history is always taken into account, as is the materials used in the fabric of the building, when we decide which cleaning system to utilize. Certain cleaning systems may remove or even destroy the masonry and other substrates. Firstly, therefore, we undertake careful investigation, samples and trials using only suitably qualified and experienced professionals prior to undertaking any cleaning to ensure that we maintain the integrity of the building.
