Different types of damp on walls

The images above show the different effects damp can have on a property’s walls. The damage damp causes to your wall will depend entirely on the type of damp problem your property is suffering from.

Damp on walls is general caused by the three types of damp listed below: 

  • Rising Damp - Rising damp can only ever affect walls the property’s ground floor. The biggest tell-tale sign of rising damp is “tide mark” on the wall above the skirting. Another common symptom of rising damp is white marks left by salts that are drawn out of the brickwork. The salts and tide mark will often cause damage to paint or the peeling of wallpaper along with a damp musty odour.

  • Condensation - Condensation very common damp problem caused by lack of ventilation. Damp on walls. caused by condensation will typically manifest as black mould spots on paintwork and wallpaper. Condensation problems are more likely to occur on cold, outside facing walls but can affect any wall in the property given the right circumstances. Condensation problems are more common in the autumn and winter months when people close their windows and increase the humidity and is particularly prevalent in bathrooms and kitchens.

  • Penetrating Damp - Penetrating damp refers to moisture ingress through a lateral wall. It is a damp problem that can penetrate walls at any level of a property. If water management systems like guttering or downpipes on the outside of your property look damaged or blocked then they are likely the source of a penetrating damp problem. Defective pointing and leaks in plumbing can cause penetrating damp.  
    On your internal walls, penetrating damp will create damp patches that damage plaster, leave water marks and leave a damp musty smell.
