FAQ

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

Why do you recheck frame items at lock-up?

Because some are still open. One Sunbury lock-up found items from the frame report not yet fixed, which is the last chance before plaster.

What does torn wall wrap do?

It weakens the barrier against wind and water behind the cladding. Tears and gaps at openings should be taped before plaster.

Do you check insulation?

Yes, for coverage. Missing batts in a few bays are easy to fit now and costly later.

Is the roof checked at lock-up?

Yes, from accessible points. Penetrations, tile positions and gutter fixing are all reviewed.

Which documents apply?

The National Construction Code, AS 1684 for framing, the roofing manufacturer's instructions and your engineering.

How long does it take?

About one to two hours depending on the size of the home.
