Causes of damp in a property

Damp

Leaks

Leaks can often be a major cause of damp within a property leading to issues such as penetrating damp and wet rot. Generally, the result of a leak will be localised to one area of a wall. If you notice localised damp patches, check the following:

  • Examine downpipes and gutters within the affected area
  • Look for damage, cracks, faulty joints or seals
  • Ensure that your drains and downpipes are not blocked. Rain water can very easily be backed up, forcing itself out of a pipe joint within the affected area
  • If the damp is below a flat roof or a roof channel, check that the felt is sound
  • If the damp is below a window, check the window frame and window sill. Badly fitted windows can also let damp penetrate into a room
  • If the damp is localised around a chimney breast, check the flashing and tiles

Rising damp

If you are on the ground floor and the damp seems to be at the bottom of walls, it could be that the cause of damp is the result of your damp proof course being bridged resulting in rising damp. This could be because of an increase of ground levels around the affected damp area or that your damp proof course has failed.

Condensation

It is not always the case whereby the cause of damp originates from the outside. One of the most common causes of damp within homes is due to condensation. Condensation occurs when large quantities of water vapour from general everyday living become trapped within a property. When the warm moist damp air comes into contact with cooler air, or a surface which is at a lower temperature, the result is condensation. This can prove ideal for the germination of the commonly associated black mould.
