We would like to get someone to re-plaster/skim our living room walls and ceiling. We recently removed the wallpaper and large sections of the walls are fine. However there are some big cracks, particularly around the corners of the room, and sections where the plaster board will need patched or replaced. The room is approximately 4.5m by 3.6m. There is a sloping ceiling on one side with a dormer window, as we are in a top floor flat.
