Inspecting decks and balconies

You need to inspect your deck at least once a year.

Even rusted nails could cause a collapse that could kill or injure someone. Check each part and the deck generally to ensure the structure hasn’t moved due the stress of swaying and twisting under load or the ground subsiding.

Learn what to look out for.

Fixings

  • Check fixings and post brackets for bending, stress, fractures and rust.

Nuts, bolts, screws and nails

  • Check for rust and replace as soon as needed.

Wooden posts

  • Check that the timber is a type that won’t degrade in soil and is treated appropriately.
  • Check for wet rot, fungal growth, or spongy or fibrous timber, and fix immediately.

Steel posts

  • Check for rust or deterioration around the base where water can pool.

Bracing

  • Check for warped, cracked or damaged bracing elements and fixings that are loose or deteriorating.

Bearers and joists

  • Check bearers and joists regularly for warping or cracking.

Balustrade anchor points

  • Check for deterioration where the balustrade is fixed to the deck or balcony, walls and posts.
  • Check that:
    • handrails are fastened securely
    • glass balustrades are free from chips or cracks
    • anchor points are free of rust and wear.
