All buildings move and settle over the years, sometimes leaving hairline cracks, but these are rarely cause for concern and are only cosmetic. The difference with subsidence is that large cracks appear both inside and outside the property in a very short period of time.
Common symptoms of subsidence include:
- Doors and windows getting ‘stuck’ and becoming harder to open or close.
- Wallpaper buckling in the corners of rooms.
- Cracks appearing in plaster inside the house, often next to doors and windows.
- Cracks appearing in brickwork outside the house.
- Sudden cracks appearing after extremely dry weather.
- Diagonal cracks that are wider than 1mm and wider at the top than the bottom.
