Many homes across the Western Suburbs, including areas such as Kenmore and The Gap, were built during the 1970s and 1980s brick home boom. While these properties are often assumed to be asbestos-free because of their brick construction, this is rarely the case. Asbestos-containing materials were commonly used behind the scenes in eaves, bathroom wall sheeting, wet area linings, and tile adhesive. These materials were chosen for moisture resistance and durability, particularly in bathrooms, laundries, and external soffits.

The Western Suburbs are also known for leafy streets and hilly terrain, which has driven extensive renovations over time. Homes are frequently extended, reconfigured, or upgraded to suit sloping blocks and modern living needs. Bathroom renovations are especially common and often disturb wall linings, waterproofing layers, and adhesive beds that may contain asbestos. Without testing, homeowners and trades risk unexpected delays, added costs, and safety issues once work is underway.
