Mould in 1950s-1970s Adelaide Brick Homes: Why They’re Prone

If your Adelaide home was built between 1950 and 1975, it has a specific set of construction characteristics that make mould almost inevitable without intervention. These homes dominate suburbs like Charles Sturt, West Torrens, Marion, and Salisbury.

The Problem with Post-War Construction No insulation: Cavity brick walls with no insulation create extreme cold bridging Single glazing: Windows drip with condensation every winter morning Minimal ventilation: Small windows, no exhaust fans, sealed-up wall vents Concrete slab on ground: No subfloor ventilation, moisture wicks through the slab The Mould Hotspots South-facing bedroom walls (behind wardrobes), original bathrooms without exhaust fans, ceiling corners where cold roof meets warm interior.

What to Prioritise Install bathroom exhaust fans ($200-$500), add wall insulation during any renovation ($2,000-$5,000), consider secondary glazing ($200-$400/window). These three changes dramatically reduce mould risk. Professional inspection identifies your home’s specific vulnerabilities. Get your free assessment.
