Does it leak only after a shower?
A leak linked to bathroom use can involve several routes. The sequence of events helps shape controlled investigation.
Separate supply, drainage and containment
A pressurised pipe, a waste connection and a failed water-containment detail can produce similar marks below. A leak that follows use is a clue, but does not identify which part has failed.
Describe timing carefully
Note whether water appears during use, while draining or some time afterwards. Tell us if a bath, basin or WC produces the same symptom. Avoid repeated testing that adds water to a damaged area.
Consider access from below
Inspection may require entry to the room underneath as well as the bathroom. In flats, arrange this through the relevant occupants and responsible owner or managing agent.
Agree the correct scope
A plumbing repair is different from rebuilding a shower area or replacing waterproofing. The package must be confirmed as suitable for the identified cause, with reinstatement arrangements understood separately.
Tell us what’s
happening at home.
A damp patch. A moving meter. A boiler that keeps losing pressure. You don’t need to know where the leak is to make an enquiry.
