John Williams and Natasja Froger try to deal with and resolve neighbor quarrels. The duo comes by to hear the details, look at the problem from all sides and propose solutions. They don't go away until everyone is satisfied, even if time-consuming bumps have to be overcome. Sometimes the solutions are very obvious, but the parties no longer have an overview. Sometimes parties cannot solve it because they do not have the correct inputs. In other cases, you just have to roll up your sleeves. From season 5, John Williams and Natasja Froger have been replaced by Jochem van Gelder and Patty Brard.
