Start with what you have noticed
Water staining a ceiling may have travelled along a joist or through a void before becoming visible. The room immediately above is a starting point, not proof of where the leak originates. Intermittent leaks are particularly dependent on their timing.
Understand what happens before the stain changes
We ask whether the damage follows showering, water use, heating or rain. Access to the room above and any relevant shared services helps plan the checks. Suitable observations and tests then distinguish possible supply, heating and fitting-related causes. Where plumbing repair is appropriate, the access and work are explained before proceeding.
Signs that can prompt an investigation
- A ceiling stain that grows after water use
- Drips from beneath an upstairs bathroom
- Recurring damp below another flat
- Water marks without an obvious exposed leak
Planning the visit
Arrange authorised access above the damage where possible. Keep people clear of a bulging or damaged ceiling and do not open it yourself just to help the investigation.
