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.
