Hi,
we have the following problem. Last year, we had mold forming in the corners of our children’s room, which we simply wiped away with Domestos. Unfortunately, we recently noticed mold again, so I took a closer look at the whole situation. However, I am not an expert. I noticed that the ceiling along the entire width of the window wall looks damp for about 30cm (12 inches) into the room, meaning it is noticeably darker than the rest of the ceiling. In addition, I can peel off the ceiling paint there!
When touching these spots, they also feel significantly cooler than the other parts of the ceiling that look normal. I then informed the landlord. He suggested that I remove the mold with alcohol and wait for the next rain to see what happens. In the corners near the window wall, the temperature is only 12°C (54°F), while the rest of the room is normally heated (about 20-22°C / 68-72°F), and during winter we have a humidity level of around 45-55%. How should I proceed now, or how can I prove that the issue is not due to ventilation and heating, but rather – as I suspect – moisture or significant cooling from the outside? It may also be worth mentioning that the roller shutters are housed in a simple wooden box that is not insulated at all.
I hope for helpful advice.
Best regards,
littlelady

thanks for all the replies. As an addition, maybe the following. The room smells musty or just different compared to the other rooms. I can rule out a rainwater pipe because it is not installed there. However, the exterior wall is not insulated, and we have a flat roof. I get along very well with the tenant, and I will definitely address this with him again and also check with the health department, since there are four people with asthma in our household, and I cannot rule out that it could be the cause, because we have been living here for four years and the complaints in two children only started here.
I find it difficult to consider a rent reduction, but health is worth it to me if he does not take action after our next conversation. His exact words were, "It’s not that bad, just wipe it away!"
What I have noticed is the following. We have a hygrometer (is that the right term?) and the concerned room always has a higher humidity level than the other rooms, despite exactly the same and very careful ventilation and heating behavior. That actually suggests that something is wrong, right? Or that it can’t be caused by ventilation, especially since we ventilate and heat the other rooms the same way and have no problems there.

Higher humidity levels obviously increase the risk of mold, which is definitely not good, especially in children’s rooms.Hi,
that is correct, but increased humidity certainly does not occur when levels always stay below 55%. Besides, I am skeptical that indoor humidity alone could soak the ceiling paint over such a large area to the point where it peels off :-)
