Damp and mould


In most cases the growth of mould is caused by condensation rather than damp

Damp is the result of a defect in the structure of your home.

Penetrating damp

Penetrating damp is caused by an external defect such as:

  • a leaking roof or gutter
  • water getting in through cracks in an outside wall
  • water getting in around window and door frames

The damp becomes more noticeable when it rains. It feels wet when touched.

Rising damp

Rising damp is caused by moisture rising from the wall at ground level to form a 'tide mark'. Although quite rare, it can rise up to a maximum of around 1 metre.

This may be the result of:

  • a failed damp course membrane
  • the level of soil outside being above the damp course

Getting help

If your home suffers from penetrating damp or rising damp it will need to be repaired before you see any improvement in problems with mould.
