How to prevent mould growing in your home

Did you know that airborne spores from mould are one of the most common triggers for allergies?


While many people know they are affected by pollen and the change in seasons, they may not realise that their own home could also be making them sick. Symptoms of mould allergy can include watery or itchy eyes, a persistent cough, asthma, dry skin, sinus problems, headaches, chronic fatigue and sneezing. An audit of your home environment and a spring clean, is the ideal way to remove and prevent toxic mould spores from your home.

Removing visible signs of house mould is essential, but changing environmental factors is the key to stopping mould from growing in your home. Rooms must be kept well aired with natural ventilation from windows and doors. The use of extractor fans in wet areas like the kitchen, bathroom and laundry also help to make your home a healthier environment for your family. Follow the steps below to help achieve a mould free home.

Step 1. Identify Areas For Potential Mould Growth

Inspect your house to determine the locations that mould could thrive in. Does your bathroom have an openable window? Is the ceiling discoloured? Is there mould on walls? Or condensation on your windows? When you’ve checked your home to detect where mould could be growing, then you can monitor the situation and implement ways to prevent mould, like installing an openable window and an extractor fan.

Step 2. Ventilate Your Home

Opening windows is the number one tip for minimising excess moisture in rooms. Mould only grows where there is moisture, so when showering, cooking or using the washer/dryer, open windows to allow ventilation of the area. Cross ventilation is the best way to prevent moisture build up in the home, so open windows or doors on the opposite side of the house to improve airflow throughout the whole house. Some windows offer greater ventilation that others. Louvre windows give ultimate control over ventilation, as you can open the whole window. Casement windows also open 100% of the window area and can direct the breeze into your home. If you have a condensation problem in your home, it may be worthwhile replacing some windows that allow greater circulation.

Step 3. Dry Wet Areas Quickly

You don’t want to leave moisture anywhere in your home for too long. Shower water should be moped up to prevent bathroom mould and wet clothes should be hung from the machine swiftly. Mould can grow very quickly, so if there is a spill or a leak, it’s best to get it cleaned up fast.

Step 4. Direct Water Away From Your Home

It’s essential to make sure that water is directed away from your home. Repair broken gutters and drains, even out land that slopes and ensure adequate drainage is installed in wet areas.

Step 5. How To Clean Mould

Mould removal can be done with anti-mould products that penetrate porous surfaces and kill mould. All you have to do is spray the affected area, wait and wash away.

Removing mould naturally is possible with tea tree oil and white vinegar:

  • Combine 2 teaspoons of tea tree oil in a spray bottle with 2 cups of water. Shake solution well before use.
  • Use an 80% white vinegar solution. Apply and leave on the affected area for at least 20 minutes, then sponge clean with water.

Remember that prevention is the best strategy to keep your home a mould free environment. Minimise the chance of excess moisture in any room to prevent mould from being able to grow.
