Mould thrives in moisture-rich environments with warmth, oxygen, and organic materials like wood, carpet, and drywall—the same conditions we find comfortable—making it a persistent issue in many homes. Since the 1970s energy crisis, homes have increasingly been built with cheaper materials, excessive insulation, and basements in areas prone to poor drainage, all of which create the perfect conditions for damp and mould growth.
The good news? While you can’t eliminate every factor that contributes to mould, you can control moisture—the biggest culprit. Here are some simple yet effective ways to keep your home, and your loved ones, safe:
1. Dry Clothes Outside
Drying clothes indoors—especially on radiators—releases large amounts of moisture into the air, increasing condensation and accelerating mould growth. A single load of washing can add over two litres of moisture to your home!
Whenever possible, dry clothes outside or in a well-ventilated room with open windows to allow moisture to escape. If you use a tumble dryer, make sure it is properly vented.
2. Ventilate Your Home
Good airflow is key to preventing condensation and mould. Open windows daily, especially after cooking, showering, or using heat-generating appliances. In bathrooms and kitchens, always use extractor fans to remove excess steam.
3. Control Humidity Levels
Aim to keep indoor humidity between 30-50% to prevent damp conditions. If necessary, use a dehumidifier or air conditioner to maintain optimal levels. Simple habits—like opening windows, using extractor fans, and drying clothes properly—can significantly reduce indoor moisture.
4. Address Leaks and Damp Spots
Even a small leak can create the perfect environment for mould. Regularly check for:
-
Water stains
-
Peeling paint
-
Musty smells
Fix leaks in pipes, roofs, or windows as soon as possible to prevent moisture buildup.
5. Keep Surfaces Dry
Mould thrives on damp surfaces, so make drying a habit:
-
After showering: Wipe down bathroom walls and floors.
-
In the kitchen: Clean up spills immediately and avoid leaving damp dishcloths or sponges sitting around.
6. Clean and Declutter
Dust and clutter trap moisture, creating an ideal environment for mould growth. Keep your home tidy by:
-
Vacuuming and dusting regularly
-
Using mould-resistant cleaners like white vinegar or baking soda
7. Use Mould-Resistant Products
When renovating or decorating, opt for mould-resistant paint, drywall, and insulation. In problem areas like bathrooms and basements, anti-mould sprays and sealants can provide extra protection.
8. Check Soft Furnishings and Storage
Soft materials—like carpets, curtains, and upholstery—can harbour mould if exposed to moisture. To prevent this:
-
Regularly air out rugs and cushions
-
Avoid storing items in damp areas (e.g., basements or lofts) without proper ventilation
Key Takeaway
Preventing mould comes down to one simple rule: control moisture. By keeping your home dry, well-ventilated, and regularly maintained, you can protect both your health and your living space. Small changes can make a big difference—start today and enjoy a cleaner, healthier home.
