Lockup (Pre-Plaster) Stage Inspection in Perth

Residential Properties • Commercial Properties

The lockup stage (often referred to as the pre-plaster stage) is the point in time when building a new house where you can "lock up" the property — typically when all windows and exterior doors have been installed.

The lockup stage is a major milestone. Once external doors and windows are in, it allows for internal appliances and fixtures (light fixtures, taps, etc.) to be installed. iSPECT Building Inspections recommend engaging a qualified inspector to complete a new home lockup stage inspection before internal plastering covers the work permanently.

Lockup Stage Inspection Perth — What We Check

This is your last opportunity to inspect before walls are sealed. Our qualified inspector will assess:

Waterproofing in wet areas
Electrical rough-in & cable runs
Plumbing rough-in & pipe work
Insulation installation
Window & door installation
External cladding & brickwork

The 4 Stages of New Home Inspection

The lockup stage is the third of four inspections we recommend during the process of building a new home:

1
Pre-Slab Stage Inspection
Before concrete is poured
2
Frame Stage Inspection
After frame approval, before cladding
3
Lockup (Pre-Plaster) Inspection
Before internal plastering begins
4
Completion Inspection (Handover / PCI)
Final check before handover

Our qualified inspectors work for you — our report will enable you to rectify any works that are substandard or not to plan, ensuring you get the home you want built for what you paid for.

Our team includes both registered builders and experienced building inspectors, each with a minimum of 10 years industry experience. The lockup stage inspection is carried out in accordance with Australian Standard AS4349. 1-2007.

Planning your Perth property inspection

Buying an established home, arranging a construction-stage inspection and documenting a property's existing condition are different jobs. Tell our Perth team the property address, the service you need and your deadline so we can confirm the scope, access requirements and quote before you book.

Choose the right inspection

A building inspection assesses the accessible building condition. Choose a combined building and timber pest inspection when you also need findings on timber pest activity, damage and conducive conditions. Check the agreed scope: one service does not automatically include the other.

Arrange access and timing

Share your agent's contact details and any inspection deadline. Let us know about locked areas, tenants, roof-space or subfloor access, and any concerns you want assessed. For an apartment or strata property, confirm whether the requested inspection includes common areas. Your report will identify access limitations.

Use the report with confidence

Read the findings, photographs, limitations and recommendations together. Ask about anything unclear and arrange specialist follow-up where recommended. For purchase conditions and deadlines, speak with your settlement agent or legal adviser. See WA Consumer Protection's property-buying guidance.
