Subsidence occurs when the ground beneath your home sinks, settles or moves. Identifying the signs of subsidence and dealing with the problem as soon as possible can help prevent any additional damage to your home. Signs of subsidence include:

● Cracks in walls, floors or ceilings – These cracks are usually at least 3mm thick. In walls, they’re likely to be wider at the top.
● Doors and windows sticking – As walls move, door and window frames may become distorted, causing windows and doors to stick or not open and close properly.
● Uneven floors – Because subsidence can cause the ground under your home to become uneven, it can lead to sloped or sinking floors.
● Extensions or conservatory subsidence and separating – If your home has an extension or a conservatory examine the joints between the extension and the main building. If it looks as if the extension is pulling away, it may be a sign of subsidence.
● Ripples or creases in wallpaper – When wallpaper acts up, homeowners often think it’s caused by damp, but if there are no signs of moisture, it may mean that the walls are moving due to subsidence.
● Leaning of the house – As the foundation shifts, the whole house may lean to one side.
● Bay windows – The historical misconception that bay windows are lighter structural elements that require a shallower foundation than the main house, leads to bay windows in older homes being particularly vulnerable to subsidence.
