Mould is not nice to be around. Not only is it unsightly and can smell bad, but it is also often directly harmful to your health

How to prevent mould

Preventing mould is essential for maintaining a healthy indoor environment. By keeping your home dry and well-ventilated, you can significantly reduce the risk of mould growth.

Create a daily ventilation routine by opening windows and doors, even for a few minutes

Ventilate to prevent mould

Proper ventilation is one of the most effective ways to prevent mould in your home. Mould thrives in damp, stagnant environments, so ensuring steady airflow reduces moisture build-up. Create a daily ventilation routine by opening windows and doors, even for a few minutes. This allows humid indoor air to escape and be replaced with fresh, dry outdoor air.

Pay extra attention to rooms with high humidity such as bathrooms, kitchens and laundry rooms and make sure to test using a mould test if you’re ever in doubt.

After taking a hot shower or cooking, moisture levels rise and can quickly lead to condensation. Use extractor fans to remove damp air and wipe away any visible moisture immediately.

Use the extractor fan while cooking to prevent mould growth

Cooking releases both moisture and grease particles, increasing indoor humidity. Using your cooker hood or extractor fan while cooking helps prevent mould growth by removing excess steam.

Turn on the fan as soon as you start cooking and let it run for several minutes after you finish to clear remaining moisture and smells. Keep the filter clean for optimal airflow, as blocked filters can reduce the fan’s ability to remove damp air effectively.

A strong and well-maintained extractor fan is key to controlling humidity and reducing the chance of mould forming on kitchen walls or ceilings.

Whenever possible, dry laundry outdoors to prevent mould build-up and keep clothes fresh

Dry clothes outdoors to stop mould growth

Drying clothes indoors raises humidity and creates ideal conditions for mould. Whenever possible, dry laundry outdoors to prevent mould build-up and keep clothes fresh. Choose a sunny, breezy day for faster drying. Sunlight naturally disinfects, while airflow helps moisture evaporate. Hang clothes with space between them to allow air circulation and avoid hanging garments near the ground where moisture lingers.

If drying indoors is unavoidable, use a dehumidifier or ensure good ventilation to stop mould from developing on walls and fabrics.

Monitor indoor temperature to prevent condensation and mould

Mould often develops when warm, humid air meets cold surfaces. Maintaining consistent temperatures throughout your home helps prevent condensation and mould growth. Set your thermostat to keep indoor temperatures steady between 20°C and 22°C. Good insulation also plays a major role in mould prevention. Poor insulation causes cold surfaces where moisture can condense, leading to damp patches and mould formation.

Improving insulation and sealing gaps around windows and doors can significantly reduce the risk of mould and improve overall indoor comfort.

Regularly inspect walls, ceilings, floors and basements for damp patches, stains or discolouration

Be aware of moisture problems

Moisture is the leading cause of mould, so detecting and addressing it early is crucial. Regularly inspect walls, ceilings, floors and basements for damp patches, stains or discolouration. If you spot signs of excess moisture, fix the issue immediately before mould has a chance to spread.

Use a dehumidifier in areas prone to dampness and ensure proper ventilation at all times. Treating even small moisture problems promptly helps prevent long-term mould damage.

Maintain and inspect ventilation systems

Effective ventilation is key to long-term mould prevention. Regularly check ventilation systems, including ducts, extractor fans and filters, to make sure they are clean and functioning properly.

Blocked or dirty filters can trap moisture and restrict airflow, increasing humidity and encouraging mould growth. Schedule periodic maintenance to keep air flowing efficiently and humidity levels stable.

To check the moisture levels you can use a moisture meter

What to do if you already have mould

If mould has already appeared in your home, act quickly to stop it from spreading. Use an appropriate mould remover spray to clean affected surfaces and always address the moisture source behind the problem. To check the moisture levels you can use a moisture meter.

For larger infestations, professional mould remediation may be necessary to fully eliminate spores and prevent mould from returning. Early intervention protects both your home and your health.
