Cladding may protect your home against rain and wind, but not automatically against moisture problems. On the contrary, in some cases, cladding can even hide moisture, allowing problems to spread slowly but surely.
That is why it is important to know how to recognize moisture problems, both on the exterior and inside the home. Because the sooner you catch it, the smaller the damage and the costs.
Cladding can hide moisture
Cladding forms an extra layer on top of the original outer wall. This layer protects against rain and wind, but it can also ensure that moisture becomes visible less quickly.
With traditional brick walls, you often see immediately when something is wrong. Discolorations on the bricks reveal that you have a moisture issue. But with clad facades, those signals sometimes remain hidden longer. That makes it all the more important to recognize subtle signs.
How do you recognize moisture problems on the exterior?
How you can recognize moisture in the facade depends on the type of cladding.
Damaged or discolored render
Render (facade plaster) is sensitive to small cracks and fissures. Even tiny hairline cracks can be enough to let water in. You can usually see these cracks. They are often accompanied by discolorations or even spots where the plaster begins to crumble. Moss or algae growth also often indicates that moisture is accumulating on or in the facade.
Wood that remains damp for a long time
Wooden cladding has a natural look but also requires maintenance. Wood reacts strongly to moisture and weather conditions. You notice problems when wood remains wet for a long time after rain, when certain areas discolor or turn gray, and when boards start to warp or expand. In some cases, you also see mold or moss growth appearing. Wood that cannot dry out lets moisture through.
Problems with sidings (plastic or fiber cement)
Sidings are low-maintenance but not completely immune to moisture problems. With sidings, the cause is often not in the material itself, but in the installation or the underlying structure. If you see gaps where there shouldn’t be any, have them repaired before you end up with moisture issues.
Pay attention to joints, connections, and details
This actually applies to all types of cladding. If you suspect moisture problems, pay close attention to joints and connections. Think, for example, of the connections around windows and doors, the corners and edges of the facade, and damaged joints. In these places, water can penetrate and spread behind the cladding.
How do you recognize moisture problems inside the home?
Because cladding can hide moisture, the first clear signs often appear inside the house. You should never ignore those signs.
Damp patches on walls and ceilings
One of the most common signs is, of course, the typical damp patches. These can manifest as dark or yellowish stains, but also as rings on walls or ceilings. They often expand during periods of heavy rain.
Peeling wallpaper or paint
Moisture affects the adhesion of finishing materials. This translates into peeling wallpaper, flaking paint, or crumbling plaster. These are clear signs of moisture in the house, possibly due to your cladding.
Mold growth
No moisture without mold. In most cases, mold in the house is due to a condensation problem or rising damp, but cracks in the cladding can also bring these unwanted guests with them.
Cold and damp walls
Does a wall feel cold and clammy? Then there may be moisture accumulation. Other typical signs are condensation forming on those cold walls and higher heating costs without you heating more than usual.
Why you should not ignore moisture problems
Moisture problems rarely disappear on their own. On the contrary, they usually get worse over time. This can lead to major consequences:
- Structural damage to the walls and facade
- Damaged insulation (with all the associated consequences)
- Health problems due to the mold that always accompanies moisture
- Decrease in the value of your home
So, tackle that moisture problem. It all starts with the right diagnosis. Not all moisture problems are the same, and each type requires a different treatment. We don’t handle penetrating damp the same way as rising damp or condensation problems. A thorough analysis, with an expert eye, is therefore necessary to determine exactly where the problem lies and how it can be solved.
