Mold in the bathroom on the grout

Hello everyone,

4 years ago, shortly after we moved into this apartment, the grout in our bathroom was renewed by a professional commissioned by the landlord.
The mold was already there when we moved in.

Even back then, we noticed because of numerous cracks that the renewal was not really done well (or were we mistaken?).

Now the mold is back again and we believe this is because the grout was poorly renewed.

Is that correct?

Otherwise, we ventilate a lot and after showering we wipe off the water everywhere as far as possible.

However, the humidity is often quite high, which is due to the high humidity.

Do the grout lines need to be renewed?

Does the landlord have to do that?

Thank you

Moisture in the joints = mold.

Neither the landlord nor anyone else can do anything about it. At most the tenant, by keeping the room and the joints drier.

The humidity is still quite high often, but that is due to the high humidity.

... and therefore the joints do not dry well. Properly ventilated even in winter? Sure, but moisture still remains in the joints...

Buy mold remover and clean the joints thoroughly and regularly. A tenant should always do this to prevent such problems.

Sorry, you probably didn't want to hear that answer. But I don't see it as being caused by poorly made joints at all.

You have to clean that yourself. The joints are well done!
