A damp wall beside a shower does not tell you whether the cause is a supply pipe, drainage, a seal or waterproofing. The most useful first step is to record when the moisture appears and stop using a shower that is causing damage. Avoid treating a new bead of silicone as a diagnosis.

Record what happens before and after use

Note whether dampness is present all the time or becomes noticeable after showering. Record which side of the bathroom is affected, whether nearby skirting has changed and whether a room or unit below has reported a stain. Photos taken from the same safe position make changes easier to compare.

Do not deliberately run the shower for a long period to reproduce a damaging leak. Do not flood-test the floor yourself. Explain any existing pattern to the person investigating and let them decide how to test without unnecessarily extending the damage.

Different possible sources need different checks

A leak associated with shower use may involve water supply connections, the waste connection or water escaping the intended wet area. An investigation should distinguish those possibilities rather than assuming every problem is failed waterproofing.

Tell the investigator about recent tap replacements, regrouting, sealant work or bathroom renovations. Useful background includes when the bathroom was last used without problems and whether any access panels or earlier reports are available. You do not need to identify the fault yourself.

Why a surface repair may not answer the question

Visible gaps or deteriorated finishes may deserve attention, but fixing a visible edge does not prove there is no concealed plumbing or waterproofing issue. Ask what the proposed repair is intended to resolve and how its result will be checked.

Similarly, a thermal image can help identify a temperature pattern worth investigating; it is not a picture of water inside the wall. Moisture readings, the history of the leak and targeted checks need to be interpreted together.

Apartments need coordinated access

If water is affecting a unit below or a shared wall, notify the building or strata manager. Renters should also notify their property manager. Provide photos, the time the issue was noticed and whether the shower has been taken out of use.

Ask who can authorise inspection and whether access to another unit is needed. Do not open common property or remove building materials without appropriate permission. Record observed damage without attributing blame before the source is established.

What to ask when booking

  • Does the first visit cover plumbing leak investigation?
  • What access or documents should be available?
  • Will any invasive testing need further approval?
  • If the cause is not plumbing, which specialist should assess it?
  • How will moisture in adjoining materials be checked?

Restored Right Group can discuss leak detection and water-damage assessment for your situation. Call urgently if water is spreading, reaching electrical fittings or affecting a ceiling. For a contained issue, request a callback with the symptom history and your suburb.

Common questions

Can regrouting fix every leaking shower?

No. The source needs to be identified first. A supply, drainage or concealed waterproofing problem may need a different response.

Should I keep using the shower while I wait?

Avoid using a shower that appears to be causing ongoing damage. Ask the attending professional what can safely remain in use.

Need help with your property?

Call with your suburb, what happened and whether water is still escaping. Confirm availability and the proposed first-visit scope when booking.
