When removing the old plaster straw mats, several chunks of the ceiling came down on me. What should I do? In my opinion, the damage should actually not be a problem. Above this ceiling is a tiled room.
Everything is possible, nothing is mandatory. Or also: no one can really tell you exactly what is going on with you here. An expert inspection wouldn't be wrong, I assume - otherwise you will always yell at the children when they stomp around again because you are afraid they will stomp a hole.
