Kitchen Mould: Behind Cabinets and Under Sinks

Kitchens generate enormous amounts of moisture from cooking, dishwashing, and boiling water — yet most Adelaide homeowners focus on bathroom mould and overlook the kitchen. Hidden mould behind cabinets and under sinks can grow for months before discovery.

Common Kitchen Mould Locations Under the sink: Slow drips from pipe joints or failed seals create a perfect dark, damp environment Behind the fridge: Warm compressor + wall condensation = hidden mould growth Inside cabinets against external walls: Cold wall + warm kitchen air = condensation Around the rangehood: If not ducted externally, cooking moisture stays in the kitchen Prevention Tips Always use a rangehood while cooking and duct it externally (not into the roof cavity). Check under sinks monthly for leaks. Leave a gap between cabinets and external walls for airflow. In Adelaide’s older kitchens with no rangehood, opening a window while cooking is essential.

Wall mould behind kitchen cabinets often indicates a deeper moisture issue. Professional assessment is recommended before any kitchen renovation to avoid uncovering — and spreading — hidden mould.
