Why does Render become
discoloured in Cornwall?

Over a period of time the Cornish weather will take its toll on your exterior walls. Render will become dirty and stained with red algae, black algae, green algae and other mildew which will result in organic staining. If you have red stains in render, this is a type of algae called trentepohlia, which in turn produces red/orange type pigment which bleeds through the rendered surface or pebbledash surface. To clean render or pebbledash and spa dash which is discoloured, the process is using a low pressure steam and a cleaning method called soft wash.
