Are you dealing with mould growth on your windows, window sills, ceilings, bathroom walls, or any damp surface in your home? Unfortunately, if you live in a cooler climate, you may have encountered the problem of mould.


Tasmania’s winters can be wet, cold and severe, leaving moisture on surfaces for long periods. Moisture in the air and condensation on surfaces around the home can result in mould if left for more than 24 hours.


Mould can appear in various colours, including black, green, yellow, pink, grey, or white, and can spread quickly. If you do not address the condensation problems and remove any mould instantly, your home can become hazardous to your health, and the affected surfaces of your home will start to be consumed by mould!

How to prevent mould growth

To prevent mould growth, it's essential to use preventative strategies. The best ways to avoid mould are maintaining proper ventilation, reducing humidity, and controlling excess or unnecessary moisture. For more information on preventing mould in your home, check out our practical tips for combating condensation.

Already have mould growing?

It's time to eliminate the mould in your home! Here are some simple and easy steps so you can learn how to get rid of mould!

Consider safety first

It's crucial to prioritise your safety when removing mould from your home. To prepare yourself for the task, it's important to wear protective gear such as a mask, gloves, and protective eyewear.


By wearing these items, you can reduce the risk of getting infected by mould spores that can enter your body through your skin, breathing them in, or getting them in your eyes from the air.

Create airflow in your home

To safely remove mould in your home, it's essential to increase airflow by opening windows and external doors before using one of the non-toxic spray solutions listed below. It's crucial to take caution when removing mould or seeking professional assistance.

Spray and wipe to remove the mould from your home!

We have compiled a list of four effective and non-toxic spray mixtures you can use when getting rid of mould. It's advisable to spray the mould as soon as it appears since it becomes more difficult to remove once it has been growing for some time.

1. Tea tree oil

Use 1 teaspoon of tea tree oil to 1 cup of water in a spray bottle, and shake to blend.

2. White vinegar

Pour vinegar straight into a spray bottle.

3. Grapefruit Seed Extract

Use 10 drops to 1 cup of water in a spray bottle, and shake to blend.

4. Baking soda

Use ½ tablespoon of baking soda in a spray bottle filled with water, and shake well to combine. Only use this spray on non-porous surfaces, such as tile and vinyl.

To remove mould, spray one of the mixtures above directly onto the affected areas. Wait 10-15 minutes, then spray again and use a micro cloth or abrasive tool to wipe it away, depending on the severity of the mould. Be careful not to damage the surface you are cleaning.


Remember that the smell of the spray will go away in a few hours. You can store each mixture in a cool, dry place for as long as you need.

When should you call a professional?

Consider the following before tackling any mould issue.

Is the mould-infected area large?

When mould is disturbed, mould spores will filter through the air and land on other clean, mould-free surfaces. The larger the mould area is, the more likely spores will spread to other areas of your home. Mould specialists can safely and carefully remove mould from any room or surface without contaminating other areas.

Is the area damaged by sewage or other contaminated sources?

Mould can emerge from various sources, such as building faults, bursting water pipes, and water infiltration in hidden areas like ceilings or under the house. To tackle the issue, you might require assistance from an electrician, plumber, or builder to fix the underlying problem. Following the repair work, a mould specialist can effectively eliminate the existing mould growth.

Does the mould keep returning?

If you have concerns about how mould may be affecting your health, it's vital to take action. If you've noticed that the mould keeps coming back, having a professional mould specialist inspect your home to diagnose the problem is best. They can determine the cause of the mould, provide a solution to remove it safely and give prevention strategies to stop the mould from returning.

Is the mould growing on porous surfaces such as wood, plaster and drywall?

Getting mould out of porous surfaces like wood and soft materials is difficult. Contacting a professional who has had experience in removing all remnants of mould will not only help to eliminate the mould but stop the mould from rotting and destroying the material.

We highly advise you to exercise caution when removing mould on your own. We suggest seeking the advice of a professional who can determine if the mould in your home requires specialised treatment and assist in identifying the root cause of the issue.
