Bathroom Mould Prevention: Practical Tips for Adelaide Homes

Bathrooms are the number one location for mould growth in Adelaide homes, and it's easy to see why. Hot showers generate enormous amounts of moisture, and many Adelaide bathrooms -- particularly in older homes across suburbs like Norwood, Prospect, and Unley -- lack adequate exhaust ventilation. Without proper moisture management, mould can establish itself on grout, silicone, ceiling surfaces, and behind tiles.

The single most effective prevention measure is ventilation. Run your exhaust fan during every shower and for at least 20 minutes afterwards. If your bathroom doesn't have an exhaust fan, or if the existing one is undersized, upgrading is a worthwhile investment. Look for a fan rated for your bathroom's volume -- most Adelaide bathrooms need at least 25 litres per second extraction capacity. Opening a window after showering also helps, weather permitting.

Other practical steps include squeegeeing shower screens and tiled walls after use, using a mould-resistant paint on the ceiling, ensuring silicone seals around the bath and shower are intact, and keeping the bathroom door open when not in use to promote airflow. If you notice early signs of mould on grout or silicone, treat it promptly before it spreads to harder-to-reach areas.

If mould keeps returning despite your best prevention efforts, there may be an underlying issue such as a hidden leak, inadequate waterproofing, or structural moisture ingress. The professionals we connect you with can conduct a thorough inspection to identify and resolve the root cause.
