Important notes: 

  • Unfortunately the majority of the ceiling plaster linings in these photos are beyond re-securing and would require replacing. It can also be very messy if insulation has been fitted above the ceilings.
  • Replacing ceiling linings can be an expensive problem that you need to be aware of when buying a property and must be addressed ASAP.
  • The longer it is left the lesser likely it can be secured without the need for replacing.
  • All ceiling linings sag to varying degrees, the problem is when they sag beyond repair.
  • The degree must be determined by a trades person that is willingly to guarantee their repair work and replace linings, where necessary.
