How do you recognise damp walls?

There are a lot of different causes of damp in walls, all of which have somewhat different symptoms. However, there are symptoms that pretty much always recur. Some are:

  • Damp or wet spots on the wall
  • A musty smell in the room
  • White, black or green mould on the wall
  • White deposit or saltpetre on the wall
  • Discoloured or detached plaster or wallpaper

Important: damp walls can manifest themselves in all rooms of a home. Not only the basement, which is often associated with moisture problems, may be related to this, but also the bedroom, living room, bathroom and kitchen may be affected.

Why is it important to do something about damp walls?

Damp walls bring all kinds of negative consequences.

  • For instance, damp walls are pernicious for the strength of your home.
  • Because a damp house is harder to heat, damp walls contribute to excessive energy bills.
  • Damp walls are also a health hazard. Moisture problems often affect breathing, airways and lungs. This is especially true for people who already have a respiratory condition. People with asthma, for example, are very sensitive to this.
  • Moisture problems are also often the cause of mould. Especially black mold is a big culprit here, as black mould is also called 'toxic mould'. These emit toxins that can lead to respiratory problems, allergic reactions, nausea, nerve and joint pain and so much more. As with general damp problems, people with respiratory diseases are more susceptible to this than others. Children and the elderly are also more likely to suffer the effects of black mould.
  • Finally, damp walls can also attract pests.

The causes of damp walls and their treatments

Damp walls always indicate an underlying problem. The most common causes are rising damp, penetrating damp or condensation damp. In addition, cold bridges or a leakage can also be responsible for wall dampness.

Possible cause 1: Rising damp

Are there moisture spots only on the ground floor? Is the moisture close to the ground and does it stop at a certain height? Then we speak of rising damp.

Rising damp is the most common damp problem. Here, ground moisture is absorbed by the walls because there is no or a deficient water barrier at ground level. The worst moisture spots may be near the ground, but it can still spread further into the wall.

The solution to rising damp: injecting damp walls

Injecting walls is the best solution against rising damp. By injecting walls, we tackle the moisture in the walls, prevent mould and prevent paint or wallpaper from flaking.

  • When injecting walls, we first of all drill a hole in the wall, close to the ground.
  • We then inject the wall with a damp-proofing substance that spreads into the pores of the wall. This way, groundwater no longer has a chance to settle in the walls and your moisture problem is solved.

Possible cause 2: Penetrating moisture

Penetrating moisture is the main cause of moisture problems in the outer walls of your home. With penetrating damp, a wall has been exposed to rain for a long time. The moisture is mainly on the outside of the house, but sometimes it can have progressed to the point where the moisture has penetrated the interior walls. At such a point, it is clear that the walls are no longer able to repel rainwater.

Penetrating moisture can be dangerous when it freezes. Because the moisture in the walls can freeze, causing cracks.

The solution against penetrating damp: impregnating damp walls

In the case of penetrating damp, the external wall is the big culprit. So that is the wall you need to have waterproofed. This can be done in three different ways.

  • Painting the exterior wall with damp-proof paint
  • (Have) your exterior wall impregnate
  • Having a new - waterproof - cladding installed

Possible cause 3: Condensation moisture

A third possible cause of a damp wall is excess condensation moisture. At condensation warm air beats itself onto the cold surfaces of windows and walls. Those walls are mainly the outside walls. These usually feel coldest when it is also cold outside.

Condensation is something that can occur anywhere in the home. It occurs most of all in rooms like the kitchen and bathroom:

  • In the kitchen, moisture from cooking hits the cold walls.
  • In the bathroom the hot water from the shower or bath provides the condensation.
  • However, the bedroom is not free of condensation moisture. In fact, by sweating and breathing, you send a lot of moisture into your bedroom space.
  • Do you also dry your laundry indoors in, for example, your living room? If so, you may have to deal with condensation moisture there too.

The solution against condensation moisture: Ventilation

Moisture in walls due to condensation is easy to solve. The major cause of condensation dampness is a lack of ventilation. So make sure you ventilate your house properly or buy an air purifier. This is a simple way to tackle condensation.

Possible cause 4: leaks

A damp wall can also be caused by leaks in water pipes or drains built into the wall. Small leaks may seem harmless at first, but they are not. In fact, they often go unnoticed for a long time. If the leak persists for a long time, the wall also becomes damp and the same consequences will occur.
