A ceiling stain under an upstairs shower
Tracing water from a first floor wet area to the room below, without lifting a tile.
In short: A defect investigation in Holsworthy traced pantry ceiling staining to water escaping the first floor shower above.
The symptom
A homeowner in Holsworthy, in south west Sydney, noticed staining on the pantry ceiling. The first floor shower recess sat directly above it.
Reading the pattern
The stain pattern pointed to water coming from above rather than condensation in the pantry, which narrowed the search to the shower.
What the investigation covered
The shower, its floor waste, tile joints and screen were examined and the ceiling below was recorded with photographs and moisture readings.
Why it matters for Cobbitty owners
Nearly every new Cobbitty home has an ensuite upstairs. The same failure would show in the same way, on the ceiling of the room below.
What comes next
The report sets out the likely cause and who should rectify it. If the builder disputes it, the next step may be an expert witness report for NCAT.
