This guide sets out good practice for diagnosing and assessing leaky (or potentially leaky) buildings. It covers the tools and techniques available to assessors and how to clearly and logically display findings and conclusions in a report. It is targeted at those who carry out detailed inspections.
The process of diagnosing a leaking building is like all diagnostic activities – it aims to balance gathering sufficient information to form the basis of robust conclusions while avoiding excessive cost or undertaking too much destructive examination.
This guidance will help an assessor address the following aspects of the diagnosis
of a leaking building.
• Is the building leaking?
• Where does it leak and why?
• What damage has been caused by the leaks?
