The mould management minefield

Winter is upon us and like most Australians at this time of the year, rugging up has become part and parcel of everyday life.

When it comes to our homes though, rugging them up too much can invite an unwanted visitor – mould!

When determining who is responsible for fixing or paying to fix a problem with mould, a lot comes down to who or what contributed to the problem.

In cases where mould is caused by condensation, whether that be as a result of heating, showering, clothes drying or the like, it is likely to be the responsibility of the property's occupants (the Renter/Tenant).

Where we find roof leaks and rising dampness, it is likely to be the property owner’s responsibility to make good the mould (the Residential Rental Provider/Landlord).

Like most things in life though, not everything is clear cut and, in many cases, you will find that there is actually a number of contributors to mould development in a property.

So what can you do to avoid mould build-up on your property?

As the occupant of the property, you can:

Make sure that you clean and use the exhaust fans; not just those in the bathrooms and toilets but also the fans in the kitchen and laundry as a lot of moisture actually comes from cooking and clothes drying!

Leave your windows, doors, and curtains open when you can to ensure that you have sufficient natural light and airflow to dry out the water created by condensation. It’s tempting to close doors and rooms off to help heat your home efficiently but it’s important that you also open those doors during the day to allow air to circulate.

If you have a split system, try running it on the dry cycle for the first or last hour of the day.

You can also regularly wipe over windowsills and skirting boards to remove excessive condensation.


There are also a number of moisture-absorbent products available from your supermarket, perfect for placing in wardrobes and cupboards.

It’s also important to be mindful of the number of indoor houseplants you have, as they too will contribute to the amount of moisture in the air in your home!

Regular vacuuming, dusting, and cleaning in kitchens and bathrooms help prevent mould. The earlier you find and remove mould, the easier it is to keep it under control. It’s much harder to remove mould once it takes hold.

And as the owner of the property you can:-

Make sure that your property’s gutters are regularly cleaned to prevent leaks.

Ensure that windows and fly screens are maintained and in good working order.

If the exhaust fans aren’t easily reached, you may want to engage a professional to clean them annually.

Install or supply a dehumidifier on the property.

When painting mould-prone areas, like bathrooms and laundries, invest in good quality mould-resistant paint.

Make sure that trees, shrubs, and garden beds are kept free and clear of the building itself to allow light and air in and around the building.

Again, if the mould persists, call in a professional.

If you do find mould, then we recommend that you:

Remove all of your furniture and other items away from the area.

Dispose of any items affected by mould immediately or carefully clean and dry them.

Remove/clean mould from affected areas if reasonable for you to do so.
