Your neighbours’ conversations in the office
Music being played by the tenant upstairs
The sound of the air-conditioning motor
The noise of water-flushing equipment
Footsteps and the floor “groaning”
An unpleasant feeling of cold in the room
Draughts by the window at the level of the back plates
On the ground or on the walls, areas in certain positions
with major differences in temperature
Black marks and even patches of mould appear inside
on the most exposed surfaces
Traces of damp and sometimes even droplets of moisture
are visible on the walls
