What it contributes
Readings taken across relevant surfaces can describe the spread and relative pattern of moisture. This supports a reasoned investigation when considered with material type and nearby plumbing.
What it cannot establish alone
Readings are affected by the substrate and instrument method. A high value alone cannot identify where water came from.
The method is selected for the conditions at the property. More than one kind of observation may be needed, and the report should make clear which findings support the proposed next step.
Before the visit
Keep existing pipe drawings and earlier findings available. Describe any restrictions on isolation, access or normal system operation. You do not need to choose or prepare a specialist test yourself.
