What is a Specific Defect survey?

A Specific Defect Survey (also known as a Specific Structural Survey or Specific Structural Inspection) is used to assess a particular problem with a property’s structure or condition. Any related building matters which are found during the inspection will also be covered. The survey goes into a similar level of detail to a Full Building Survey, but does not cover the whole property, just the specific area of concern.

Specific Defect Surveys are suitable if you believe that the rest of the property is sound, but you have concerns about one aspect. This could be something that you have spotted in a property you wish to buy.

A survey would allow you to get detailed information on the extent of the issue and the costs of rectifying it; this would allow you to make an informed decision on whether to proceed with the purchase or renegotiate the price. Alternatively, it could be something in your own home that you want to check for peace of mind, perhaps before carrying out building works. Sometimes a vendor may wish to get a second opinion on an issue highlighted by a purchaser’s survey, to aid negotiations.

Examples of issues a Specific Defect Survey could address include:
– Cracking or bowing of walls or beams; suspected instability or movement of walls or floors (subsidence)
– Timber rot or infestation
– Damp
– Non-standard construction
– Issues with brickwork quality
– Problems with supporting structures such as beams
– Issues with the quality of specific aspects of the building or alterations, such as wall removals and loft conversions
– Roofing defects For more information about the expert investigations we offer, please visit our residential services page.


The survey report includes detailed descriptions of what is found during the building inspection, alongside relevant photos. It states whether or not there is a problem with the structure of the building, and if there is, what needs to be done and how much it will cost to rectify the problems found.
