"Battling the Damp: Tackling black mould in Australian Homes"

In some regions of Australia, black mould is a common issue in homes, particularly due to the humid subtropical climate, which provides ideal conditions for growth. Exposure can cause numerous health issues, especially for individuals with respiratory conditions, allergies, or weakened immune systems. Common health effects include:

  • Respiratory problems (e.g., asthma, bronchitis)

  • Allergic reactions (e.g., sneezing, runny nose, red eyes, skin rash)

  • Headaches and fatigue

  • Eye, nose, and throat irritation

What causes black mould?

  • Humidity: A humid climate contributes to high indoor moisture levels, which promote growth.

  • Poor Ventilation: Inadequate ventilation in homes can trap moisture, especially in areas like bathrooms, and kitchens.  

  • Water Leaks: Leaking roofs, pipes, or windows can introduce moisture into the home, creating a perfect environment for growth.

  • Condensation: This often occurs on windows and walls, especially in winter, when warm indoor air meets cold surfaces.

 How can I prevent it?

  • Improve Ventilation: Ensure proper ventilation in all rooms, especially in high-moisture areas like bathrooms and kitchens. Use exhaust fans and open windows when possible.

  • Control Humidity: Use dehumidifiers to maintain indoor humidity levels below 60%. Air conditioners can also help control humidity.

  • Fix Leaks Promptly: Address any leaks in roofs, walls, and plumbing as soon as possible to prevent moisture buildup.

What do I use to clean it?  

  • Small Areas: For small black mould patches (less than 10 square feet), you can clean them yourself.

  • Soap and Water: Use a mixture of dish soap and water to scrub the black mould off non-porous surfaces.

  • Vinegar: Spray white vinegar directly onto the area and leave it for an hour before wiping it off.

  • Hydrogen Peroxide: Use 3% hydrogen peroxide in a spray bottle, spray on the affected areas, let it sit for 10 minutes, and then scrub.

  • Baking Soda: Mix baking soda with water or vinegar to form a paste, apply it to the area, scrub, and then rinse.

When to get Professional Help

For large areas with significant black mould problems, it may be necessary to hire professional. These experts can assess the extent of the problem, identify the source of moisture, and safely remove.

 What are my rights as a tenant?

Landlords are responsible for ensuring their rental properties are free from health hazards, including black mould, due to structural issues. Tenants need to make a report in writing to the Property manager.

By taking proactive measures and addressing any black mould issues promptly, homeowners and tenants can maintain a healthier living environment.
