To stop mold in the house, the key is to control moisture, maintain proper ventilation, and keep the house dry and warm. Here are the main strategies:

• Control moisture: Mold grows from moisture, so eliminate any water leaks quickly and dry wet areas promptly. Fix plumbing leaks and repair any structural defects that cause dampness. Use dehumidifiers, especially in basements, to keep humidity below 60% (ideal 30-50%).
• Ventilation: Ensure proper ventilation by opening windows and doors when possible to let fresh air circulate. Use exhaust fans in the bathroom and kitchen to expel moisture from showers and cooking.
• Heating: Keep the home sufficiently heated to avoid cold spots where condensation can form. Recommended temperatures are about 20°C in living rooms, 23°C in bathrooms and children's rooms, and not below 14°C anywhere.
• Drying: Avoid drying clothes indoors on radiators as this increases indoor humidity. Instead, dry clothes outside or use a vented dryer.
• Clean and remove mold: Clean moldy surfaces with mold removal products or a mixture of water and detergent. Remove and discard materials that are heavily moldy or cannot be cleaned, such as carpets or mattresses.
• Additional tips: Use mold-resistant paints and materials when renovating, keep blinds/curtains open to allow sunlight, and air out wardrobes and cupboards regularly.

Implementing these measures can effectively prevent mold growth and maintain a healthy home environment.
