Garage and Shed Mould: Prevention Tips for Adelaide

Garages and sheds are often the forgotten spaces when it comes to mould prevention. Yet stored belongings, tools, and vehicles create conditions where mould thrives — damaging your possessions and creating a spore source that affects the rest of your home.

Why Garages and Sheds Get Mouldy

Poor ventilation, concrete floor moisture, and temperature fluctuations create condensation on metal surfaces and stored items. In Adelaide, garages built on reactive clay soils (common in Mitcham and Tea Tree Gully) often have moisture rising through the slab.

Prevention Strategies

Install passive ventilation (wall vents or whirlybird). Keep items off the floor using shelving. Don’t store cardboard boxes directly on concrete. Ensure gutters drain away from the structure. For persistent moisture, a mechanical ventilation system may be needed.

If mould has damaged stored items or spread to walls, a mould inspection can assess the extent and recommend remediation. View typical costs.
