Mould reduction in Melbourne

Why buildings here are at risk

Melbourne does not have Brisbane’s humidity, and building managers often conclude from that they do not have a mould risk. The mechanism here is different. Winter minimums sit low for months, interiors are heated continuously, and the temperature differential across external walls, single-glazed windows and uninsulated soffits produces condensation on a daily cycle from roughly May to September. Sustained surface moisture at moderate temperature is ideal for colonisation.

The building stock

A large inventory of pre-1990 office and institutional stock with limited wall insulation and original glazing. Victorian and Edwardian conversions across Fitzroy, Collingwood and South Melbourne with solid masonry and rising damp. Newer apartment and mixed-use towers where sealed construction and under-specified ventilation trap occupant-generated moisture.

What we get called for

Winter complaint spikes in offices and schools. Condensation-driven growth behind joinery and in ceiling voids that is invisible until it stains through. Strata and owners-corporation disputes across a dense apartment market.
