A stain is not its cause

A small mark under a sink can prompt a useful question. In this fictional photograph, the observation is a color change around the cabinet base and back-panel corner.

The image alone does not tell us when it appeared, whether it is damp now, or what caused it. No moisture readings or fixture-test results are supplied in this example.

Rather than jump to ‘it is leaking,’ separate the observation from the questions that remain.

If a similar mark concerns you, prepare the questions for an on-site professional. A comment-thread photograph is not a substitute for assessing the conditions.
