Sandstone masonry cleaning

Sandstone is very porous and could easily be destroyed if saturated or have any pressure or chemical applied. We gently cleaned this sandstone facade with the TORC Heritage cleaning System. TORC Cleaning is a way to clean exterior surfaces of brick and stone with little to no need for chemicals. Instead, it uses a mixture of water and very fine calcium carbonate to clean using just high-pressure air and a splash of water.

Breathe new life into dirty and tired facades

A sample will always be carried out to assess the least intrusive method required to achieve the best possible result. Close consultation with our clients ensures customer satisfaction, as well as best practice in terms of future maintenance, protection and preservation. 

Pmac breathes new life into building facades and public areas by removing grime, growth, grease, oil and carbon deposits from stone surfaces. Our specialist stone cleaning services cover facade cleaning, walkways, bridges and pavements. We also rejuvenate modern renders such as Monocouche,Techrete and Cladding. These are very thin renders that can’t withstand any pressure cleaning and must be treated with extreme care. If you have grimy and damaged stone or render, we can clean and restore it.

Stone Repairs and Stone Replacement

Once a building is cleaned we can assess for repairs. Our Masonry craftsmen are on hand to source and replace damaged stones. We also have extensive experience repairing damaged and chipped stones, filling in holes and finishing facades to an extremely high standard.

As a registered Heritage Contractor, PMac combines the best traditional craftsmanship with modern techniques and materials to accomplish an excellent finish, achieving the best possible protection for the future.
