When water appears in one flat and the suspected source is the property above, the inspection has to separate emotion from evidence. This Balzan case involved damage below an upstairs bathroom, with the affected client needing to understand how wet the structure still was and what should happen before reinstatement.
The Problem
Water had entered the client’s flat from the area of the neighbour’s bathroom above. The worst visible damage was in the bathroom and corridor below, but surface appearance alone was not enough to judge whether the walls and ceiling were ready for repair.
This type of case is common in apartment blocks, which is why ceiling leaks from upstairs should be checked carefully before anyone starts blaming the wrong area.
Thermal Imaging Findings
Thermal imaging showed that moisture remained inside the affected structure even where some finishes had started to look dry. That matters because repainting or closing the area too early can trap moisture and lead to staining, bubbling paint, mould risk and repeat disruption.
For wet walls, ceilings and corridors, a damp and moisture inspection can help decide whether drying is complete enough before reinstatement.
The Backyard Concern
The client also asked us to check the backyard, which sat below the neighbour’s terrace. The moisture pattern was more noticeable during or after rain, indicating that terrace detailing above also needed attention.
This did not replace the bathroom finding. It showed that there may be more than one moisture source, which is why terrace checks, rainwater paths and internal plumbing should be treated separately.
Practical Advice Given
The advice was to remove damaged wallpaper and avoid sealing damp limestone too early. Vapour-open finishes, ventilation and assisted drying can help the structure dry properly before decorating begins.
The upstairs owner also needed to inspect the bathroom and terrace details, including grout lines, upstands and any penetrations, so the source of moisture could be repaired rather than covered.
When neighbours, insurers or property managers need a clear record, a written leak detection report can document the inspection findings and recommended next steps.
