Remediation details: other work

Other than remediation work referred to on other pages such as replacing cladding and flashings, removing parapets and removing and replacing windows, other work may also need to be undertaken.

Weathertightness-related work

Work that may need to be specified as part of any weathertightness remediation project includes:

  • removal of attachments to the cladding – washing lines, downpipes, handrails, barriers, pergolas or decks
  • the full or partial removal of spouting and fascias, particularly where they have been installed before the cladding or where a fascia gutter system is installed on a building with no eaves
  • removal of fascia and barge boards
  • lifting of waterproof deck membranes and removal of rainwater heads
  • repainting the remainder of the building to bring maintenance up to date and to improve the light reflectance of the cladding where dark colours (that generate higher thermal movement) have been used
  • replacing damaged wiring where TPS has been in contact with expanded polystyrene
  • detailing rainheads
  • air sampling to determine if contaminants are present
  • replacing curtain rails
  • basement wall waterproofing reinstatement or repair
  • installation of vents to suspended ground floors (as well as laying polythene over the ground on wet sites).

Issues other than weathertightness

Issues other than weathertightness that may also be identified during building condition and remediation surveys or as remediation work proceeds include:

  • lack of structural performance of framing, floor joists, deck joists and bracing
  • faults in fire resistance rated construction in multi-unit dwellings
  • faults in acoustic construction in multi-unit dwellings
  • inadequate internal and external barriers (or no barriers where there should be)
  • lack of handrails
  • unsafe electrical installations
  • plumbing leaks
  • corrosion of fixings due to the higher moisture levels – a sample will need to be removed to determine the extent of the deterioration
  • damp subfloors in buildings with suspended timber floors due to ponding water and/or a lack of subfloor ventilation
  • dampness under timber-slatted decks, particularly where a cladding finishes below the deck – some of this moisture may get into a drained cavity space.
