Penetrating damp

Penetrating damp can be damaging to a property even if it does not penetrate all the way through a wall. It is most commonly caused by problems with the roof, brickwork or windows.

What is penetrating damp?

Penetrating damp, otherwise known as lateral damp, is the end result of water successfully penetrating from the outside of a building and into your property.

Unlike rising damp, penetrating damp can happen at any level within the property including roofs, ceilings and walls.
It is a very common problem found within older properties that have solid walls. Newer properties tend to have much more protection from penetrating damp through the use of cavity walls and are therefore less likely to suffer from this type of damp problem.

What causes penetrating damp?

Penetrating damp is most commonly caused through leaky pipes and poorly maintained brickwork, which over time can become damaged or need re-pointing. Deterioration of mortar joints and water management systems are also a typical cause of penetrating damp.
