Under the floor

Soil

Reactive clay

Moderately to highly reactive clay (Class M to H). Seasonal movement causes hairline cracking in brickwork and render. Modern slabs are engineered for it; older strip footings were not. Consistent moisture around the house is the whole game.

In the walls

  • Party walls and shared driveways on community or strata titles
  • Small setbacks mean little garden and less solar access
  • Quality varies enormously between developer-builders
  • Neighbourhood character disputes
  • Asbestos in eaves, bathroom, laundry and fence
  • Galvanised pipes and low water pressure
  • Empty wall cavities (no insulation)
  • Original switchboard with ceramic fuses
What each of these costs to fix
