Wet area rectification is the most expensive defect category in a new house, because reaching a layer worth a few hundred dollars means dismantling a finished room. The shower recess is where it starts, and the Austral records show it examined at lock-up before the tiler was anywhere near it. The photographs below were taken in Leppington, Oran Park or Austral, between two and eight kilometres from Catherine Field, and each caption names its suburb. We would rather tell you that than let another job pass as a local one.

Two or three days is normal between the membrane curing and the tiler arriving, which is why the booking has to be arranged ahead rather than on the day.
A damp skirting, or a stain on the far side of the wall in the next room, always behind finished tiling and always expensive.
Anything still open is assessed, and the parts already sealed up are noted as such.
The builder owns it, and has to bring the waterproofer and the tiler back in sequence. The report hands them the location together with the clause.
