Sydney's housing eras — and the defects each one hides
Sydney housing spans six major construction eras: Victorian (1840–1900), Federation (1900–1920), Interwar (1920–1940), Post-War (1945–1960), Late-Twentieth-Century (1960–2000), and Contemporary (2000+). Each era has a signature defect profile — Federation weatherboards struggle with rising damp; post-war brick veneers hide asbestos in eaves; 1990s builds often need cavity re-flashing; modern builds fail at waterproofing junctions.
Pest & Building Inspections Australia inspectors are trained to recognise the era at first look and adjust the inspection focus accordingly. That's why our reports catch defects that generic checklists miss.
