The Various Types of Damp and How to Avoid Them

Damp is a problem that has plagued homeowners for centuries. The onset of modern Building Regulations has gone a long way to addressing the cause of these problems but the blight of damp is ever present, especially within older properties.

This article will provide an overview of the different types of damp you may experience as well as how to combat them.

What is Damp?

Damp found within a building refers to the presence of water or moisture. There is rarely a good reason for your internal walls and surfaces to be wet so the presence of moisture indicates a problem. If left untreated, damp can be hazardous to health and result in a number of issues such as the growth of mould.

Rising Damp

Most people are familiar with this term and often mistake their moisture problems to be a symptom of rising damp. In actual fact, rising damp is fairly rare.

Rising damp is usually caused by ground water entering your property through a broken damp proof membrane or through the presence of a failed or broken damp proof course, where water is allowed to enter your home and climb the walls.

The symptoms of rising damp might include;

  • Peeling wallpaper or plaster based wall coverings
  • Bowed and splayed skirting boards
  • Visible tide marks on your wall
  • Lifting floor coverings

Rising damp will first need to be identified where a solution can then be presented, usually the installation of new damp proofing.

Penetrating Damp

As the name suggests, this type of damp is caused by water penetrating through the external structure of your home. This could either be through the roof structure or through your walls. Large cracks in your walls are a great way for water to enter your property.

Symptoms might include;

  • Large pools of water resting on surfaces
  • Large patches of water on your internal walls
  • Large patches of wet ceiling

Penetrating damp needs to be rectified by identifying the source of any water penetration. Once this is done and repaired, your home will dry over time where you can then begin to repair any damaged internal surfaces.


The third type and probably the most common is condensation based damp. This type of damp is caused by heightened levels of humidity and condensation present within your home. The cause of this will be poor ventilation in most cases.

The likely symptoms are;

  • Unexplained wet patches in the middle of walls
  • Constantly wet window frames, sills and panes of glass
  • The presence of mould where surfaces have been wet for a while

The most common course of action is to provide appropriate ventilation in the form of trickle vents on windows as well as the installation of extractions fans.
