ᐅ Mold in the bathroom on the grout lines

Hello everyone,

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

At that time, we noticed many cracks and felt that the renewal was not done properly (or were we mistaken?).

Now the mold has returned, and we believe this is because the grout was poorly renewed.

Is that correct?

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

However, the humidity is often quite high, which may be due to the high moisture levels.

Do the grout joints need to be renewed?

Is the landlord responsible for this?

Thank you

Moisture in the joints = mold.

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

... and because of that, the joints do not dry out well. Is the room properly ventilated, even in winter? Of course, but moisture still remains in the joints...

Buy mold remover and clean the joints thoroughly and regularly. This is something tenants should always do to prevent such problems.

Sorry, this probably isn't the answer you wanted to hear. But I don’t think the issue is due to poorly done joints.

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