We are buying a house and want to address moisture issues in the laundry room: about 15cm (6 inches) above the baseboard, mold has developed in several corners and caused the wallpaper to peel. According to the current seller, this has been the case for around 10 years, since they bought the house back then. The plaster is not completely wet, but damp.
Apparently, they didn’t pay much attention to it. The moisture does not come up from the floor, but rather the room’s humidity simply accumulates there. The rest of the house is dry.
The current occupant has a dryer in the laundry room, occasionally hangs laundry there, and there is only a small window. Presumably, they do not follow correct ventilation practices (seasonal differences like summer and winter).
Question: Is it sufficient to remove the damp plaster, replaster, and paint the entire room with a vapor-permeable silicate paint? Then, minimize drying laundry in the room itself and follow proper ventilation rules? (We do not have a dryer.) Or should a specialist definitely be involved?
Example picture attached.
Thank you

Even I, as a layperson, would immediately suspect ground moisture—or the joint between the wall and the foundation slab.
And I would stay far away from something like that right away… it’s not a minor issue.

Sebastian7920 Sep 2015 13:51Did they have X-ray vision? I wouldn’t put much weight on that opinion—without a proper inspection, you’ll only get guesses here as well.
But I wouldn’t take it so lightly... there is a high potential for significant expenses behind this.

Sorry, but I don’t see any drama here. The moisture from the laundry has to go somewhere, and if the room isn’t properly ventilated, this is what it looks like.
I would suggest letting it dry and observing what happens if you don’t dry any laundry there for 4 weeks.
Best regards,
Dirk Grafe
