Our experience and knowledge of external façade cleaning and restoration means there is very little that we haven’t dealt with before. 

Each building must be assessed by one of our leading experts who will work with you to maintain the integrity and authenticity of the building we are working on but also to ensure we achieve the desired outcome. 

The extent of the required clean-up will determine not only the technique used to but also the equipment used to scale and work our way around the building. Each building, particularly listed buildings, brings with it it’s own unique set of challenges such as access.

Every material specified will be treated in a way which will clean up, restore and extend the design life of the façade.
