ᐅ Damp or moisture in the wall caused by inadequate ventilation after screed installation

Dear building experts,

In my father’s new house, the walls are cracking as if they were tectonic plates.

He told me that 3-4 weeks passed between the screed installation and the first ventilation.

It seems to me that moisture has penetrated the beams of the prefabricated house, causing the building to now "move."

Can anyone advise me on how to deal with this? Or where the regulations are regarding how builders are required to ventilate?

Thank you very much for your advice.

I don’t understand. Then you would be a doctor, not a doctor (gender-neutral).

@Snowy36 @driver55: Could you please continue your discussion via private message?

I’m concerned that it not only dilutes the thread but also discourages others from following and contributing their thoughts.

Ok, he is living in the house now. So, where are the cracks appearing? At the wall-to-ceiling joints or within the walls affecting the plaster or wallpaper? He’s allowed to take pictures inside his own house now, right? How many weeks or months have passed since the screed installation and moving in?

It shouldn’t be that difficult…

He has been living there for one year now.

Attached are some of the areas where cracks have appeared. But there is practically no wall in the house without cracks.

There are quite a few, but they are very straight and seemingly narrow... surely not settlement cracks?

What kind of base surface is it—just plaster or is there a painter’s fleece underneath?
We only have plaster, so it’s normal for cracks to appear, for example, in corners and transitions, or in places where, for instance, ventilation is installed. But with you, it seems to be quite a lot.

These all look like completely normal settlement cracks.
Were the joints of the drywall panels beveled?
Were they finished with mesh tape?
