The defects worth knowing first.

  • Entry № 001 · Compliance

    Climbable Horizontal Members or Excessive Gaps in Balustrade

    I inspected a balustrade on a deck, balcony, or stair with a drop greater than 1m and found horizontal rails, lattice, or decorative infill a child could foothold, or I measured gaps between vertical members wider than 125mm. When I test the lower portion with a sphere gauge I find climbable surfaces in the zone 150-760mm above finished floor. Reference: NCC 3.9.2.5 (non-climbable zone in effect since 1996). I see this on both post-1996 builds and older homes that were rebalustraded without the rule being considered.

    Bath Hob and Surround Missing Waterproof Membrane

    I inspected the bath hob, step-down, and vertical wall returns and could not confirm a continuous waterproof membrane behind the tiling. Reference: AS 3740. In my experience overspray and splash then tracks into the sub-tile substrate over time. I see this most on renovations completed before the post-2004 tightening, and still on recent unlicensed work.

  • Entry № 003 · Termite

    Concealed Slab Edge

    The slab edge is hidden from view by paving, soil, garden beds, or render, preventing visual inspection of the most likely termite entry point on a modern brick-veneer home. AS 3660.1 and the termite-management standard both require a minimum 75mm of exposed slab edge at every external wall so an inspector can see whether termites have bridged between the soil and the wall framing.

    Diagonal or stepped cracking in load-bearing masonry walls indicating differential settlement or foundation movement, commonly found in older Perth and Sydney homes on reactive clay soils.
