A weep hole asked for at practical completion

The right finding at the wrong stage.

Owner Inspections · Catherine Field 2557 · 2026-01-30

In short: A weep hole recorded as required at an Austral handover inspection.

What a weep hole is for

Draining the cavity. Water crossing the outer brick skin runs down the inside face, lands on a flashing, and leaves through the weep hole. Take away any part of that and the water stays in the wall.

What was recorded

Weep hole required, at high severity, on an Austral practical completion inspection about eight kilometres north of Catherine Field.

Why the stage is the story

At lock-up this is a bricklayer and a chisel. At practical completion the brickwork is finished, sometimes rendered, and putting it right means cutting into completed work.

How the conversation goes

The builder resists, for exactly that reason. What moves it is a report citing what the detail fails, with a dated photograph attached, rather than a description of how the wall looks.

What to do about it on your build

Book lock-up. Every envelope item we see arriving late belongs at that stage, and it is the cheapest inspection in the sequence relative to what it can save.

FAQ

Questions Catherine Field owners ask about this

Is it a major defect?

Water through the envelope is the commonest category argued as major. The argument is much easier with the clause and the photograph in hand.

How many weep holes should a wall have?

They sit along the base of the cavity and above openings, at the spacing AS 3700 and the code require. A stretch of wall with none is easy to see; uneven spacing has to be measured.

Can it be fixed properly after rendering?

Yes, but it is invasive and it will be visible. That is the cost of finding it late.

At what point ahead of handover should I book?

Two to three weeks, so the builder has a genuine window to act.
