Perhaps you need both a mason to fix the existing damage and a waterproofing company to fix the underlaying problem?
I'm sorry but I don't have specific recommendations for either.
If water is the issue, I'd contact Gregory Watetproofing or Avellino.
I'm guessing it's a combination of factors. Water behind the walls. The paint and cinderblock is peeling and crumbling. Mason? Painter? Handy man?
