Making sense of moisture readings
A number is more useful when you know the material and context.
Compare like with like
Different materials and meter modes can produce different readings. One isolated result should not be treated as a universal moisture percentage.
Look at the distribution
A pattern across the affected surface can help describe where moisture is present. Rooms above, nearby plumbing and recent decoration provide context.
Test the explanation
System checks and other evidence help determine whether the pattern is consistent with an active plumbing leak or needs another line of investigation.
Put the information into context
This guide explains common investigation principles. Your property, the available access and the actual test findings determine the right next step. It is not a diagnosis of an unseen system.
