Mould Exposure in Children: Risks Every Parent Should Know

Children breathe faster than adults, have developing immune systems, and spend more time on floors and in enclosed spaces. This makes them disproportionately vulnerable to mould exposure — and the consequences can be lasting.

Why Children Are More Vulnerable

A child’s respiratory system is still developing until around age 6. Mould spore exposure during these critical years has been linked to increased rates of asthma development, chronic rhinitis, and lower respiratory infections. Studies show children in mouldy homes are 40% more likely to develop asthma.

Symptoms Parents Often Miss

Children may not articulate symptoms clearly. Watch for: persistent “colds” that never fully resolve, disrupted sleep due to congestion, reduced appetite, behavioural changes linked to fatigue, and frequent coughing — especially at night or upon waking. Full health risks guide.

Adelaide Hot Spots

Families in older Adelaide homes — particularly stone and brick houses in Burnside, Unley, and Mitcham — should be especially vigilant. These homes often have rising damp and poor ventilation that creates ideal conditions for the black mould and wall mould that affect children’s bedrooms on exterior walls.

If you suspect mould is affecting your child’s health, don’t wait. Book a professional inspection and get connected with qualified specialists who can make your home safe again.
