Local case study 3: Arundel, mould in an enclosed under-stair cupboard

Local Case study 2: Pimpama, mould around an ensuite exhaust fan
Fine speckled mould spreading out from an ensuite exhaust fan, with nothing wet and nothing sagging. The owner wanted to know if water was getting in. The answer was above the ceiling, not behind it.

Why does mould keep coming back on the bathroom ceiling?
It is the same ceiling every time. Above the shower, around the fan, or a grey line following the cornice all the way round. You wipe it, it looks fine for a few weeks, and then it is back in exactly the same place. Bathroom ceilings are the most common thing we get called to on the Gold Coast, and across the jobs I did in July it came down to the same three things over and over.
