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

  • Asbestos possible to about 1987
  • Halogen downlights against insulation
  • Leaking showers as waterproofing membranes reach 25-35 years
  • Grey polybutylene pipe in some 90s homes
  • Asbestos still present in wet areas and eaves to the mid-80s
  • Single-glazed dark aluminium windows
  • Original ducted systems at end of life
  • Some concrete driveways and slabs cracking on reactive clay
What each of these costs to fix
