Conditions Conducive To Structural Damage Including:

Defective Plumbing and Defective Roof Plumbing and Flashings including:

  • Non-existent rainwater goods including flashings, gutters and down-pipes
  • Lack of general storm-water drainage
  • Faulty, decayed or lack of parapet / chimney flashings
  • Cracked or decayed roof cladding
  • Inadequate pitch / lap of roof cladding / no sarking
  • Faulty / decayed vent / flue flashings
  • Decayed ridge cappings, gutters and down-pipes

Defective / Bridge Damp Proof Course including:

  • Non-existent damp-proof course in masonry walls
  • Failed / defective damp-proof course
  • Bridged damp-proof course by: earth, mulch, path, floor, rendering, re-pointing and additions

Shoddy Work including:

  • Construction which is obviously unsatisfactory / even dangerous
  • Construction which has been built without regard to any recognised standard
  • Repairs to the building structure of a superficial / makeshift nature
  • Materials unsuitable for the purpose for which they were intended
