Hi, I have just started removing wallpaper from my bedroom wall and have discovered two parallel (either side of the corner) vertical cracks going through the plaster in the corner of the room. It is where the previous owners had a wall mount for a TV and one of the cracks runs through the drill holes. Can anyone help suggest possible causes of this and whether I should be worried about subsidence? Also, does anyone have any suggestions on how I can fix this?
