Clearstone Southwest provides stone and masonry cleaning, restoration and conservation for commercial and public buildings throughout South-West England, including Cornwall, Devon and Plymouth.

Our system cleans stone surfaces of moss, lichen, and algae, along with the build-up of dirt to leave them looking almost like new — and all without using chemicals which damage plant life, are dangerous to pets and wildlife, and degrade the environment generally.

Absolutely no bleaching agents and
100% environmentally friendly

Beware companies which claim to be eco-friendly. Many of these ‘eco-friendly’ companies use chemicals harmful to animals and vegetation, and which end up entering the drains and eventually rivers, causing damage to the ecosystem.

Our system uses nothing but superheated water. The spray reaches a maximum temperature of 150°C. This is high enough to remove biological matter such as moss and algae and also kill off spores to stop regrowth.

And once any debris removed during the cleaning operation has been disposed of, the water simply drains into the ground, and causes no environmental damage whatsoever.

Absolutely no surface damage

Even better, although our cleaning process is powerful, the water pressure is low and very gentle.

This means the surface being cleaned — including stone with lime mortar — won’t suffer any damage (unlike jet washing and other abrasive techniques).

The small amount of water used in the process also ensures the surface never becomes saturated and is therefore usually dry within minutes.
