The different kinds of damp are:-

Rising damp:

Rising damp is an unsightly form of dampness that can affect not only the health of your property but depending on the extent of the rising damp issue, can potentially affect your own health or family members, if not quickly treated. Most common within older properties where the original damp proof course may be failing or damaged, rising damp can lead to the breakdown of the wall plaster resulting in damaged internal decorations, skirting boards and walls. If the rising damp is not professionally treated this type of damp can easily reoccur.


It is thought that condensation affects about one in five properties in the UK. Condensation is perhaps the most annoyingly common root cause of damp problems in homes and buildings. It is caused by warm vapour filled air ‘condensing’ when it contacts with cold surfaces like walls or windows. It leaves behind drops of water (condensation) on the surface. If left untreated, condensation can lead to damp walls, causing unhealthy living conditions and black mould growth. Ant Construction has a selection of professional condensation solutions to eradicate the most serious and persistent problems.

Penetrating Damp:

Penetrating damp (also known as water ingress) is the result of water infiltration from the outside of a property to the inside. It can be caused by things such as rain from a faulty drainpipe at the property and can also include damp from high ground levels. It is, however, an issue that can affect all buildings with solid brick or stone walls.
