Improperly repaired external wall defect - what to do?

But that is already a topic, because with slow, slightly immediate pressing the door is never closed. Especially not with children! However, I do not know exactly how this could affect possible crack formation.

and of course trust a bit in what my father says

That's exactly it... we can't assess what kind of impact it could have if the door is regularly slammed shut.

That's why I pointed out the need to nip things in the bud and make clear whose opinion territory this house is.

Oh yes, I think I misunderstood that earlier.

Ok, so it is not to be expected that a serious problem will arise at some point because of this matter.

Would you refrain from the complaint about defects?

There is this old teacher trick called upbringing, which significantly influences whether you raise terrorists. The diverse offspring of the patchwork family in my neighborhood even greet in the stairwell. Slamming doors is by no means innate; you learn that from bad role models. In single-family homes, you can even install PVC front doors as a "cheapskate" *shudder*
