DOFF is a steam based cleaning system. High temperature and low pressure, capable of heat up to 150 degrees, it is ideal for treating stone. The operator is able to control the temperature and pressure to be appropriate for removing different types of biological matter, paint, algae, moss and general build up of dirt, without damaging a property’s exterior, and without the use of potentially harmful chemicals.


The patented TORC system features a low-pressure vortex, that uses small volumes of water, air, and fine inert granulate to achieve a gentle and effective method of cleaning stone masonry. Intended to remove some of the most difficult staining, TORC tackles carbon sulphation, lime and cement based paints, bitumen and limescale.


Nebulous cleaning is a system of intermittent mist sprays. The sprays can be set up at intervals along a structure, focusing on spaces in more need, and reducing levels where there is less dirt. Water can be regulated by enabling intermittent spraying so that water can be stopped at the appropriate clean to the building exterior.
