Enclosed (Lock-Up) Inspection in Flagstone
The enclosed, or lock-up, inspection checks your new Flagstone home once it is weather-tight — roof, cladding, windows and external doors on — but before the internal linings hide the wall cavities. VG Inspect carries out an independent, QBCC-licensed enclosed inspection across Flagstone and the surrounding Logan estates, checking external cladding, brickwork or render, articulation joints, weep holes, head flashings and roof penetrations against NCC Volume 2 Part 3.5 and the relevant Australian Standards. You receive a same-day digital report with every item photographed and referenced. This is the stage where the building's weather defences are confirmed before they are sealed up — a smart checkpoint on any Flagstone new build, and especially on the high-set and split-level homes common across the releases.

Why a enclosed (lock-up) inspection matters in Flagstone
Once the internal linings go up in your Flagstone home, the wall cavities, flashings and the back of the cladding are hidden permanently. The enclosed stage is the only practical opportunity to confirm the home is genuinely weather-tight — that flashings direct water out of the cavity, weep holes are clear, articulation joints are positioned to suit the reactive clay, and the cladding is fixed correctly per NCC Volume 2 Part 3.5. In the Logan corridor's storm-prone climate, water that gets into a wall because of a missed flashing or blocked weep hole can cause damage that only shows up months or years later, behind finished surfaces. Catching it at lock-up, while the cavity is still open and accessible, is far simpler and cheaper than tracing a hidden leak after handover.
Local conditions in Flagstone (4280)
The reactive clay that runs through most of Flagstone's release area, classified around H1 or H2 under AS 2870, makes articulation (control) joints especially important on brick-veneer and rendered homes, because they let the structure accommodate seasonal soil movement without cracking the cladding. With a mix of low-set and high-set product across the sloping estates, lock-up is the right time to confirm the weep holes are clear and correctly spaced, the cavities are clean of mortar, and the window and door head flashings shed water out of the wall. On the corridor's storm-prone summers, getting the roof penetrations, junctions and flashings genuinely weather-tight before the linings go on is well worth verifying — particularly where a stepped roofline follows the slope of the block.
What we check at the enclosed stage
The enclosed, or lock-up, inspection happens once the home is weather-tight — roof, external cladding, windows and external doors are on — but before the internal linings hide the wall cavities. It is the stage where the building's weather defences are checked before they are sealed up. Here is what we check against NCC Volume 2 Part 3.5, the relevant Australian Standards and the manufacturers' specifications:
External cladding & masonry
- External cladding, brick veneer or render checked for installation, fixing and finish per the manufacturer's specification and NCC Volume 2 Part 3.5.
- Articulation (control) joints provided and positioned correctly to accommodate movement, especially on reactive soils.
- Weep holes left clear and at the correct spacing, and wall cavities checked clean of mortar droppings.
Flashings & weatherproofing
- Window and door head, sill and jamb flashings installed to shed water out of the cavity.
- Roof covering, ridge, valley and penetration flashings checked per NCC Volume 2 Part 3.5.
- Sealants and junctions at penetrations, meter boxes and service entries confirmed weather-tight.
Openings & enclosure
- Windows and external doors installed plumb, operating correctly and sealed to the frame.
- Sarking / wall wrap continuity and lapping checked where still visible before linings.
- Roof space and eaves inspected for framing, batten and sarking installation before ceilings are fixed.
Every item is photographed and referenced to the relevant Australian Standard, NCC clause or the QBCC Standards and Tolerances Guide, then delivered in a same-day digital report you can hand straight to your builder.

Enclosed (Lock-Up) Inspection FAQs — Flagstone
What is an enclosed or lock-up inspection in Flagstone?
It is the inspection carried out once the home is weather-tight — roof, external cladding, windows and external doors installed — but before the internal plasterboard and linings cover the wall cavities. It focuses on the building's weather defences: cladding, flashings, weep holes, articulation joints and roof penetrations.
Why do articulation joints matter on Flagstone homes?
Flagstone's reactive clay, typically classified H1 or H2 under AS 2870, moves with seasonal moisture changes, and articulation joints let a brick or rendered wall accommodate that movement without cracking. We confirm they are provided and correctly positioned at lock-up, along with clear weep holes and clean cavities, so the cladding performs as designed over the life of the home.
When should I book the enclosed inspection?
Once the home is at lock-up — weather-tight with cladding, windows and external doors on — but before the internal linings start. That timing lets us see the flashings, cavities, weep holes and roof penetrations while they are still accessible and can be photographed for your report.
How much does an enclosed inspection cost in Flagstone?
Enclosed (lock-up) inspections are from $550 with a same-day digital report and no travel surcharge across Flagstone and the wider Logan City Council area. It pairs well with a frame inspection for full coverage before the internal linings go on.
