Black mould can be a problem in many homes, especially when it’s cold and damp outside. It’s not just ugly to look at; it can also be bad for your health. The good news is, you can keep it away by managing the temperature and air flow in your home.
In this guide, we’ll show you some simple steps to help prevent black mould from setting up shop in your space. Let’s take a look at how you can keep your home cosy and mould-free!

Step 1: Set the Right Temperature
Aim for Consistency:
- Aim to maintain a steady indoor temperature, ideally at 18°C or above, especially during colder months. This helps prevent condensation, a common culprit for mould growth.
Step 2: Ventilate, Ventilate, Ventilate
Kitchen & Bathroom:
- These areas are mould hotspots due to their moisture levels. Make a habit of opening windows or using exhaust fans during and after cooking or showering to let out steam.
Bedrooms & Living Areas:
- Regularly air out these spaces by opening windows, especially during dry days. Fresh air can help keep moisture levels down and prevent mould.
Step 3: Monitor Humidity Levels
Use a Dehumidifier:
- A dehumidifier can be a game-changer in damp areas or during wet seasons. Aim to keep indoor humidity below 60% to create an unfriendly environment for mould.
Step 4: Regular Home Check-ups
Look for Signs:
- Every week, check common problem areas like windows, corners of rooms, and behind furniture for signs of condensation and mould. The earlier you catch it, the easier it is to deal with.
Step 5: Seek Professional Advice When Needed
Don’t Hesitate:
- If mould has already taken hold in your home, or if you’re unsure about the adequacy of your ventilation, consult a professional. They can provide tailored advice and solutions.
Step 6: Educate Everyone in the Home
Make it a Team Effort:
- Ensure everyone in the home understands the importance of good ventilation and how to prevent mould. It’s a team effort that can lead to a healthier living environment.
