Mold remediation in the laundry cellar?

Warm air normally condenses higher up and not just down there at the edge.

But sure, you can tell the seller to not dry anything for 1-2 months and then decide ;)

Especially basements and moisture plus such casual statements would make me VERY cautious...

Moisture condenses at the coldest spot.

As I read the ET, the purchase is done.

Especially basements and moisture plus such casual statements would make me VERY cautious...

I have undergone a basement renovation with 4 complete exterior walls myself. If it is only one spot in a room that is also used for drying laundry and presumably poorly ventilated, then I honestly see no reason to panic. Especially since a professional has already examined the place on site, whose judgment you (for whatever reason) doubt.

I also didn’t write anything about panic - but you are too relaxed here with me.

But if it’s already done anyway, I would then do nothing for 1-2 months and see what happens.

Of course it condenses at the coldest spot - but it is usually at the top in the ceiling area.

If there is underfloor heating above or generally a warm room, then the top is simply not the coldest spot. When the dryer is running, it also produces heat that rises upwards, so it is warm at the top and cooler at the bottom.

Even if it should come from outside/below, it can be managed.

Ich habe auch nichts von Panik geschrieben - mir bist Du hier aber zu gelassen.

Yes, because almost every house on the street has such a corner and, as I said, I had significantly more damages of this kind in the house.

: that is the problem: the laundry room is located in a building that we might buy/have to buy next month. Until then, we have no influence.

More detailed about the condition: The laundry room is not heated by the current landlord; it only contains a washing machine and dryer. The ventilation through the basement window seems to happen arbitrarily so far, usually it is just always open.

The moisture on the walls is exclusively in the floor area, 15-20 cm, but not continuous. However, several spots are affected that look similar to the corner in the posted picture.

These damages are found on both the outer wall and a completely internal wall. There, however, only on the laundry room side. The other side of the internal wall (towards the basement corridor) is also dry. If the moisture rises from the floor, shouldn’t both sides be affected?

All other rooms in the basement, including, for example, the unheated storage room, are dry.

Basically, all rooms have underfloor heating. Since the kitchen is above, the ceiling of the laundry room is therefore partially heated. Thus, I suspect that the greatest cold or moisture occurs on the basement floor.

With the description, I would then also agree with Dirk - it's still not nice.
