House moldy - Should mold be removed?

That looks catastrophic! The question shouldn’t be “Does the mold have to be removed” but rather “Does the house have to be removed.” I wouldn’t dare go out on the street anymore, but everyone to their own.

So for me, it’s okay! Our summer house in Serbia is a catastrophe. But my wife is heating me up right now! “Ivo,” she says, “in Serbia it’s okay! But in Germany, the 3 cm corners at the entrance just don’t work.”

Maybe you should listen to your wife more often.
