Adelaide Winter Mould Season: Your Preparation Checklist

Adelaide’s mould season runs May–September. Preparing your home before winter dramatically reduces the chance of mould taking hold. Use this checklist to get ahead of the problem.

Before Winter Checklist

• ☐ Check all exhaust fans are working in bathrooms and kitchen
• ☐ Clear gutters and downpipes of leaf debris
• ☐ Check subfloor vents are unblocked
• ☐ Inspect roof for potential leak points
• ☐ Move wardrobes and furniture 50mm from external walls
• ☐ Check window seals and weatherstripping
• ☐ Service heating systems (ducted and HVAC)
• ☐ Buy a hygrometer ($15-$30) to monitor humidity
• ☐ Ensure you have a plan for drying clothes (NOT indoors without ventilation)
• ☐ Clear garden vegetation from house walls for airflow

During Winter Habits

• Run exhaust fans 15 minutes after showering/cooking
• Open windows briefly each morning for air exchange
• Target indoor humidity below 60%
• Wipe condensation from windows promptly

If mould appeared last winter, get a pre-winter inspection to fix the cause before it happens again. Take our risk assessment and get connected with specialists.
