Survey Timing and Process
Optimal Survey Timing
Pre-Completion Inspection
Conduct snagging survey 1-2 weeks before completion date when property is substantially finished but before handover.
Best Practice: Developer must rectify all identified defects before completion
Post-Completion Follow-up
Conduct follow-up inspection 6-12 months after moving in to identify settling issues and warranty claims.
Important: Identifies issues not apparent at completion but still covered by warranty
Year Two Review
Final inspection before builder warranty expires and NHBC coverage begins for structural issues only.
Critical: Last chance for builder rectification of non-structural defects
Professional Survey Process

Developer Remediation Process
Typical Remediation Timeline

Step 3: Remediation Works (Days 5-21)
Developer's contractors complete remediation works, typically requiring 1-3 weeks depending on scope and complexity.
