Why it matters here

Lock-up (pre-plaster) inspections on Werribee builds

Lock-up on Werribee builds tends to catch services and insulation rather than structure: ducts crimped in the roof space, batts missing from walls, sarking left off a tiled roof and a sewer junction placed inside its clear zone.

What we find at this stage in Werribee

  • Ducts crimped or bent too tightly
  • Wall batts missing or gapped
  • No sarking under a tiled roof
  • Sewer junction inside the 450mm zone
  • Gutters holding water
  • Upper floor sheets squeaking

FAQ

Lock-up (pre-plaster) inspections in Werribee: common questions

Why look at insulation before plaster?

Because a missing batt cannot be seen once the wall is lined, and gaps reduce the energy rating the home was designed to achieve.

What does a crimped duct do?

It restricts the air reaching that room, so the heating and cooling work harder for less effect.

Do you check frame items again at lock-up?

Yes. Anything still open from the frame report is looked at again and recorded as fixed or not fixed.

Is sarking always required?

That turns on the roof type, the lot's wind class and what your specification calls for. Where it is specified and missing, we record it for the builder to confirm.

Do you test the plumbing at this stage?

No. We look at visible pipework and junction positions; pressure testing belongs to the plumber.

How long after the inspection can plaster go on?

As soon as the items are fixed. Send the report to the supervisor the day you receive it.
