1) Moisture on the bottom of walls

 Rising damp

Moisture on the bottom of the walls is almost always caused by problems with the pipes below or behind said walls. In case of rising damp it’s ground water rising in the walls. You can solve this in one of these 2 ways: inject your walls or put in an entirely new damp-proof course.

Injecting your walls means that, after drilling holes in them, you have to squirt damp-proof gel into the walls.

2) Moisture on the outer wall

⇒ Penetrating damp

If you have obvious damp spots on your outer wall (and if they run through to even the inner walls), then you’re dealing with penetrating damp. The reason why this moisture is seen through the facade, is because the wall cover has turned porous. That’s why it often occurs with older buildings. Penetrating damp can be dealt with in 2 ways: impregnate the walls or replace the facade coating.


Injecting walls can be done by applying an invisible damp-proof coating to your outer walls. This prevents the moisture from seeping through and creating damp spots.

3) Mold

⇒ Condensation

Condensate on the windows, mold in the bedroom, kitchen or bathroom… They are all signs of condensation. This problem is caused by too little ventilation. When you cook, or take a bath, lots of vapour is released, and if it cannot leave your house, it will condensate and form mold. Luckily there’s a simple solution: ventilate!


Mechanical ventilation prevents condensation and moisture and makes sure you live in a healthy environment.

4) Other moisture problems

Do you have a damp problem that cannot be explained with the above-mentioned causes, then there’s a big chance that there’s a leak in one of the pipes. For this, it is best to have a leak detection carried out by a damp expert.

By applying the wrong technique, you could cause loads of unnecessary work and the cost could be immense. So getting to the root of the problem is the first, crucial step in treating damp.
