mould growth, which is a cause of respiratory allergies.
mildew, salts, staining and ‘tide marks’.
damage to surface finishes.
corrosion and decay of the building fabric.
slip hazards.
frost damage.
poor performance of insulation.
damage to equipment, or electrical failure.
the most common causes of persistent damp in buildings are:
