Why it matters here

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

Most leaks we trace in new Truganina homes begin with a lock-up detail: a broken tile underlap, wrap not taped around a window, a weep hole full of mortar. With no temporary downpipes, roof water also lands right beside a slab that sits on reactive clay.

What we find at this stage in Truganina

Cracked tiles and broken underlaps on the roof
Weep holes filled with mortar
No temporary downpipes connected
Strap bracing left slack
Wrap missing between garage and house
Wall batts incomplete before plaster

FAQ

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

How does a lock-up visit differ from the frame visit?

Frame looks at the structure before it is covered. Lock-up looks at what now closes it in: roof, wrap, windows, brickwork and insulation, and confirms the frame items were fixed.

Is the roof itself walked at a Truganina lock-up?

Yes, where it is safe. Broken underlaps and cracked tiles are often only visible from the roof itself.

Why are missing temporary downpipes written up?

Without them, roof water discharges straight beside the slab for weeks. On reactive clay that wetting is exactly what the footing design tries to avoid.

Which standards govern the lock-up stage?

AS 3700 for masonry, AS 2047 for windows, AS 4773 for brick, the NCC roof and wall cladding provisions and the manufacturers' flashing details.

Are wall and ceiling batts checked at lock-up?

Yes, visually. Missing or displaced batts are recorded, since this is the last chance to see wall insulation.

How long does it take?

One to two hours on site for most Truganina homes.
