What can affect your quote?
- Floor area and storeysThe published bands step up with size; a double-storey house takes longer to bring down and produces more material.
- Construction typeFibro and weatherboard come down faster than brick veneer, and full brick or concrete takes the longest to sort and remove.
- AsbestosBonded asbestos removal is quoted from the assessment. Friable asbestos is removed by our Class A licensed partner.
- Access and machineryNarrow frontages, battle-axe blocks and steep sites limit the machine we can bring in, which changes the time on site.
- Pools, slabs and retaining wallsStructures beyond the house are priced as their own items so you can see what each one adds.
- Council, certifier and utility feesApproval and disconnection fees are set by others. They are itemised separately in your written quote.

Do I need council approval to demolish a house in Wahroonga?
Wahroonga is split between Ku-ring-gai Council and Hornsby Shire Council, so we first confirm which council’s rules apply to your address. Gabrael prepares and lodges the application and confirms whether the work goes ahead as a DA or a CDC once we have checked the planning controls for your address.
