What is a Level 3 Building Survey?
The most comprehensive survey available for residential properties. Every defect is identified, explained, and accompanied by professional guidance on repairs, urgency, and next steps.
The service includes:
- Thorough inspection of all accessible areas
- Opening up where access is permitted
- Detailed defect analysis with photographs
- Remedial guidance and repair options
- Prioritised recommendations
More than visual: Where safe and permitted, we open hatches, lift loose floorboards, and inspect concealed areas that Level 2 cannot reach.
Who needs a Level 3?
Period Properties (Victorian & Edwardian)
Complex construction, period features, and often hidden defects that need expert assessment.
Converted Buildings & Subdivisions
Properties converted to flats or with unusual layouts require deep structural understanding.
Known Defects or Concerns
If previous surveys or your own observations flag issues, Level 3 provides the detail you need.
Large or Complex Properties
Multi-unit buildings or properties with unusual construction benefit from comprehensive analysis.
Properties in Poor Condition
Run-down or neglected properties where the scope of required works needs proper assessment.
What the survey includes
- ✓Full interior and exterior inspection
- ✓Roof spaces, sub-floor areas where accessible
- ✓Opening up where safe and permitted
- ✓Detailed structural assessment
- ✓All defects documented with photographs
- ✓Remedial options and repair guidance
- ✓Prioritised recommendations by urgency
- ✓Post-survey discussion and support
Report length:
Typically 30–40+ pages of detailed findings, photographs, and professional recommendations.
What's not included
- ×Testing electrics, gas, plumbing, or heating
- ×Specialist structural engineering assessment
- ×Asbestos sampling or environmental testing
- ×Drainage or underground investigation
- ×Valuation (separate instruction if needed)
- ×Legal advice on boundaries or rights
Where we identify concerns that need specialist investigation, the report clearly recommends next steps.
Level 3 goes further than Level 2 – but it is still a surveyor's inspection, not a specialist contractor's investigation.
