Stage 4: Lock-Up
Pre-Plaster

A lock-up stage inspection is conducted when the building is enclosed with the roof, external cladding, windows, and doors installed. This is sometimes called the pre-plaster stage as it occurs before internal plastering begins. It also includes a free visible frame reassessment to verify any previously noted frame issues have been addressed.

The lock-up inspection focuses on the building envelope including roof cladding and fixings, gutters and fascia, external wall cladding, window and door installation, flashings, insulation, and weather sealing. It verifies the building is weather-tight and structurally sound before internal lining begins. We also reassess any visible frame elements at no extra charge.

Proper weather resistance at lock-up stage prevents water ingress that can cause timber rot, mould growth, and structural damage over time. Incorrectly installed flashings, poor sealing around windows, or gaps in cladding can lead to moisture entering the wall cavity. These issues become hidden once plastering is complete, making early detection critical.

During the lock-up inspection, our inspectors reassess all visible frame elements at no additional cost. This confirms that any defects identified during the earlier frame stage inspection have been rectified by the builder. It also allows us to check for any new issues that may have developed since the frame inspection.

All defects are documented in a detailed report with photographs. You can then present this report to your builder who is required to rectify the issues before proceeding. Our reports provide clear evidence to support your position and ensure compliance with building codes.

Our promise is a full report within 24 hours of your inspection completion, guaranteed. Reports are delivered via cloud-based online link, PDF email attachment, and SMS link for convenient access.

No. As the property owner, you have the right to arrange independent inspections at any stage of construction. Most building contracts include provisions for owner inspections. If your builder objects, this may be a warning sign worth investigating further.

Council inspections verify minimum compliance with building regulations and are typically brief. Our independent stage inspections are far more thorough, checking workmanship quality, Australian Standards compliance, and identifying defects that council inspectors are not required to assess.
