People / companies decide to clean Natural Stone Buildings and Monuments for a number of reasons;
· It could be a building with historical interest or distinctive architecture and used for public viewing.
· To allow the building to reflect its original design.
· To improve the appearance of the building, as by having a clean stone building, it will in turn reflect a good company image.
· Prevent the deterioration of a building and maintain its condition.
It is important to carry out cleaning of natural stone as over time stone buildings can attract dirt, algae and lichens. If these are to collect on open joints and cracked stonework, over time it is likely to disguise the need for repairs. This can be unsightly, cause deterioration of the building and increase the extensiveness of repairs. It can also speed the deterioration process up by trapping water into the building and preventing it from escaping.
