Pre-Completion vs Post-Completion Snagging Inspections

Conducted before legal completion, during your builder’s notice period.
Helps you identify and report cosmetic snags early, so the builder can address them before you move in.
Provides reassurance that your home meets the minimum quality standards of the New Homes Quality Code (NHQC).
Typically limited to visible, surface-level defects: paint, tiling, doors, windows, skirting, etc.
Strictly visual only: cannot use specialist equipment or check hidden services (pipes, electrics, insulation, underfloor heating, damp, air leaks).
Developer permission is required; inspections are often strictly time-limited (usually 1–2 hours).
A helpful early check but for the most thorough evaluation of your home, we strongly recommend a Post-Completion Snagging Survey.

Conducted after legal completion, once you have full ownership and access to your home.
The most comprehensive inspection option, designed to identify any defects missed at earlier stages.
Thorough, room-by-room independent survey with detailed notes and photographs.
Includes full testing of both visible and hidden areas, using advanced equipment such as thermal imaging, moisture meters and Survey Instruments.
Detects hard-to-spot issues like insulation gaps, air leakage, underfloor heating faults, damp, and water ingress.
No developer permission needed: you control access and timing.
Strongly recommended to ensure all defects are fully identified within your builder’s 2-year warranty period.
Many buyers choose this inspection for maximum peace of mind.
