About Demolition in St. Marys

St. Marys falls within the Penrith City Council area and features heavy stock of 1950s–1970s fibro homes — significant asbestos workload. We work regularly across St. Marys and surrounding suburbs including Mount Druitt, Werrington, Erskine Park, Colyton, Oxley Park.

Local Considerations

Council approvals: Penrith City Council requires either a CDC (issued by a private certifier) or a DA for demolition. We can advise on the right pathway and supply demolition methodology documents.

Service disconnections: Sydney Water, Ausgrid and Jemena disconnections must be confirmed before demolition starts. Allow 2–6 weeks lead time.

Neighbour notifications: Adjoining-owner sign-off is often required where boundary walls or shared fencing are affected.

Hazardous materials: Many homes in St. Marys built before 1990 contain bonded asbestos — we test and remove as part of the demolition.
