http://cleanandcolourroofing.com/walls/ The exterior walls of your home are to an increasing extent, exposed to micro-organisms which are transported through the air. These growths manifest themselves in coloured deposits such as algae, mould, lichen and others.

These micro-organisms need water to live. They themselves in turn harbour moisture which provides a fertile ground for further growths and deposits.

The cause of these increasing growths is as follows:
■Increased environmental pollution from harmful
substances from cars, industry and power stations
■Altered climatic causes, increased humidity
■Increased shade caused by trees and planting in residential
estates
