Penetrating Damp Signs & Causes

What Is Penetrating Damp?

Penetrating dampness occurs generally as a result of poor external maintenance, i.e. defective rain water goods (gutters), which will allow rain water to penetrate the structure of the building. This can happen when the external renders are cracked, because of spalled brickwork, or even due to roof defects.
