Why it matters
Why arrange a Building Survey?
A Building Survey helps you move beyond a simple list of defects. It explains how the property appears to be performing, why defects may have occurred, how they may be rectified, and what could happen if repairs are ignored.
- Understand defects before purchase or major works
- Identify damp, cracking, timber and roof-related concerns
- Get more detailed commentary on construction and building fabric
- Understand likely causes, repair priorities and urgency
- Learn the consequences of delaying essential repairs
- Identify issues that may require further specialist investigation
- Support negotiation, budgeting and confident decision-making
Survey comparison
Building Survey/Level 3 vs Home Buyer/Level 2
A Home Buyer / Condition Survey gives a practical overview of visible condition and is suitable for many standard homes. A Building Survey is more detailed and is better suited to older properties, altered buildings, extended homes, larger, higher-value or complex properties, with deeper commentary on construction, visible defects, likely causes, repair options and consequences of non-repair. If you are unsure which survey is right, we can help you choose the appropriate level based on age, construction, condition, complexity and intended use.
Speak to National building consultants before you commit to buying, leasing or renovating, so you understand the property's condition, risks and repair priorities first.
