The point to understand
A mark can have a plumbing, weather-related or condensation explanation. Its appearance alone is rarely enough to decide what needs repairing.
Put it into practice
Observe whether the area changes after rainfall, heating or particular water use. Compare nearby materials and keep records of previous treatments.
Keep the limits in view
Moisture mapping supports an investigation. It is not, on its own, proof of a broken pipe or a replacement for a building survey.
