Rising damp on walls

Rising Damp

Watch this short video to find out more about rising damp and how it affects properties.

Rising damp is an issue that will only affect walls on the ground floor of a property. You can generally tell if you have a rising damp issue by the typical “tide mark” often left on the wall above the skirting board. It is often associated with white efflorescent salts which are drawn out of the brick work with peeling wallpaper and a damp musty smell within the affected rooms.

Condensation damp on walls


Watch this short video to find out how condensation problems occur in a property.

Condensation is by far the most common form of damp on walls. Generally, condensation on walls is most evident when the condensation festers and allows black mould to germinate. You will generally notice this on outside facing walls where the wall is colder however, it can be quite random and will certainly appear more often within the winter months particularly in bathrooms and kitchens.

Penetrating damp on walls

Penetrating Damp

This quick video shows the tell tale signs of penetrating damp from outside a property.

Penetrating damp (or moisture ingress as it is often known by) is a damp issue that can affect walls at all levels of a property. It can quickly saturate a wall and penetrate through to the inner walls. You can generally tell if you have a penetrating damp issue on your walls by examining the outside of the property to look for defective water management systems such as broken guttering or pipes. Defective pointing and plumbing can also be a common reason for penetrating damp appearing on walls.  

Internally, evidence of penetrating damp on walls can include damp patches that never seem to dry out, damaged plaster, water marks on masonry and damp musty smells.
