Our company, Historic Building Restoration Ltd, specializes in stonemasonry and stone cleaning services, utilizing authentic Torc and Doff systems. Our skilled operatives, trained by Stonehealth, are adept at cleaning various types of stone and brick, both indoors and outdoors.

The Doff system is a steam-based cleaning method that stands out for its ability to reach temperatures up to 150°C at the nozzle. Operators have control over temperature and pressure, making it effective in removing paint, graffiti, bird fouling, algae, and other biological matter.

With the Torc system, we create a gentle swirling vortex using low air pressure, minimal water, and safe granulate. Its modularized design allows for efficient cleaning with even less water and granulate than previous systems. The interchangeable nozzle cone accommodates different cleaning needs, from large areas to intricate details.
