Stone Cleaning
In some instances, stone cleaning techniques have proved to be damaging, especially to sandstone and limestone, with the introduction of chemicals and abrasive methods that can remove or destroy the stone’s natural protective layer (patina).
Think carefully before instructing a contractor to undertake a stone cleaning scheme for aesthetic reasons. The dark coating that develops on stone structures is a natural product of aging and helps to protect the stone. Bear in mind that its removal may accelerate the rate of natural stone decay.
Where it is deemed necessary to proceed with a stone cleaning project, special consideration needs to be given to sensitive cases such as historic structures and listed buildings where the use of abrasive techniques or chemicals can seriously harm the surface of the structure.
If you own a listed property, be aware that you may have to seek consent before any cleaning work can be undertaken.
We offer a range of sympathetic cleaning methods dependent upon the type of façade, the sensitivity of the structure, and the extent of staining. Please contact us to discuss your specific circumstances.
