Do you see yellow stains or brown damp patches on your wall? Then it is better to tackle these in time, because the stains indicate an underlying problem. Usually it is a moisture problem, but sometimes there are other causes. Do you want to know exactly how these yellow or brown stains appear on your wall? Then read how to trace the possible causes yourself.
Yellow and brown spots due to moisture problems
Usually, yellow and brown spots are caused by an underlying moisture problem. It may be that your wall feels wet due to rising damp, or that moisture seeps in from outside. Then you are dealing with penetrating damp or one or more leaks. A leak can occur because your exterior wall is in poor condition, or because there is an old pipe in your wall that is leaking. Also on painted walls where the yellow and brown spots have been visible for some time, the paint will gradually peel off and affect the surface.
Yellow and brown damp spots due to poor ventilation
Does your wall look intact and does the surface even feel dry? Then you may be dealing with poor ventilation, which is often the case in new or recently renovated/insulated homes.
Especially in well-insulated homes without ventilation, yellow and brown spots will appear more quickly. This indicates that the living moisture indoors is affecting the building materials, which can create a breeding ground in which moulds develop more easily.
Yellow and brown stains in older homes
Do you see yellow and brown spots on walls that need renovation? Then there is a good chance that the building materials themselves are the cause, for example if the water barrier is of poor quality. In outdated homes, there are often metal pipes in the walls, where the metal oxidizes and leaves a brownish color on your wall. Is there a rusty or leaking pipe in your wall? Then there is a good chance that you will see brown damp spots on your wall as a result.
The older the house, the greater the stain formation. This is because the cause is not only due to moisture problems, but also to the general poor/rotten condition of the walls themselves. Is this the case? Then you will also see similar stains on your ceiling and other walls in your home.
And finally, the cause may also lie with the occupant himself. Has someone smoked or burned wood in the house for years with an open fireplace? Then the stain formation is often the result of the soot and smoke that has penetrated the walls. In this case, the house also spreads an unpleasant and musty smell.
Tackling yellow and brown damp spots in time
If you wait too long to tackle damp spots, mould or mildew will develop, especially on the yellow and brown damp spots. Mould formation not only affects your walls but also your health, so it is good to tackle moisture problems in time.
