Start with what you have noticed
A leak into a flat may originate in another home, a communal riser or a shared supply. The stain alone does not establish ownership or responsibility. A useful investigation needs access to the relevant spaces and an understanding of the building layout.
Coordinate the investigation across boundaries
We ask when water appears, which activities affect it and what the managing agent already knows. Accessible fittings and suitable system checks help narrow the likely route. Where the findings support a plumbing repair, the access and authorisation requirements are explained before work proceeds.
Signs that can prompt an investigation
- Water appearing from the flat above
- Intermittent stains below a bathroom
- Damage near a communal riser
- Uncertainty about which supply is affected
Planning the visit
