Timber slat decks – deterioration of decking/cladding

Cause

Decking and framing was installed hard against the building cladding 

Repair

  • create a separation of the deck and building cladding: temporarily support the deck adjacent to the building, remove stringer and re-install with 10 mm minimum packing off the wall cladding to provide drainage. Re-fix joists to stringer. Ensure decking also has a minimum 10 mm clearance from the cladding to provide drainage
  • where it is suspected that the building may be leaking and there is a risk of damage, engage a building surveyor to report on the building

Accumulated dirt and debris is trapped against the cladding
