Common Subsidence Issues in Portslade
Diagonal Cracking
Cracks running diagonally from window and door corners are one of the most common signs of subsidence. These typically widen over time if the underlying cause is not addressed.
Sticking Doors & Windows
When foundations move, door and window frames can distort, making them difficult to open or close. This is often one of the first signs homeowners notice.
Gaps Between Walls & Ceilings
Separation between internal walls and ceilings or floors can indicate differential movement in the foundations beneath the property.
Rippling or Bulging Walls
External walls that appear to bow or ripple may be experiencing lateral movement caused by foundation failure or ground heave.
Sinking or Uneven Floors
Ground floor slabs that slope or feel uneven can be caused by settlement of the sub-base or erosion of supporting ground beneath the property.
Cracked Rendering or Brickwork
Stepped cracks following the mortar lines in brickwork, or cracked render on external walls, are classic indicators of structural movement.
