Demolition companies play a big role when you decide to knock down a house in Sydney. Whether you’re clearing a block for a new build, removing an old weatherboard in the Inner West, or taking down a double-brick home in the Hills District, understanding how demolition companies work will save you time, stress and money. This guide walks you through everything you need to know about hiring demolition companies for house demolition in Sydney.

What Do Demolition Companies Actually Do?
Demolition companies handle the safe and legal removal of houses and other structures. In Sydney, that usually means:
· Full house demolition (single or double-storey)
· Partial demolition (keeping parts of the house you want to save)
· Asbestos removal (very common in pre-1990 homes across Sydney)
· Site clearing, tree removal and rubbish disposal
· Disconnecting services (water, power, gas, sewer)
· Recycling materials like bricks, timber and metal
Good demolition companies in Sydney do more than swing a wrecking ball – most use excavators with special attachments, and some still do careful hand demolition in tight spots like Paddington terraces or Lane Cove bush settings.
Safety First – Why It Matters in Sydney
Sydney’s dense suburbs and sandstone soils make safety non-negotiable. Reputable demolition companies follow strict WorkCover NSW rules and Australian Standards (AS 2601). They must:
· Set up exclusion zones and scaffolding
· Use dust suppression (water trucks or misting systems)
· Monitor noise and vibration (especially near neighbours in Bondi or Mosman)
· Have traffic management plans for narrow streets in Surry Hills or Balmain
A licensed contractor carries public liability insurance and workers compensation – always ask to see the certificates before work starts.
Permits and Regulations in Sydney
You can’t just knock a house down tomorrow. In Sydney, demolition companies help you get these approvals:
· Development Application (DA) or Complying Development Certificate (CDC) from your local council
· Section 140/138 approval from Sydney Water for sewer work
· Dial Before You Dig report
· Asbestos clearance certificate if the house was built before 1990
· Waste classification for the tip (most Sydney houses go to Kembla Grange or Eastern Creek)
Many councils (Randwick, North Sydney, Canada Bay, etc.) now require a Waste Management Plan showing how much material will be recycled – Sydney demolition companies usually aim for 85–95% recycling rates.
How Demolition Companies Price House Demolition in Sydney
The cost depends on several local factors:
· Size and construction type (fibro is cheaper than double brick)
· Access – easy bulldozer access vs crane work in tight Leichhardt streets
· Asbestos presence (a big factor in most Sydney homes)
· Tree removal and retaining walls
· Distance to recycling centres and tipping fees in greater Sydney
Experienced demolition companies give fixed-price quotes after a free site visit so you know the exact figure upfront.
What to Expect When You Hire Demolition Companies in Sydney
Here’s the usual timeline for a standard house demolition in Sydney:
1. Free quote and site inspection
2. You accept quote and pay deposit
3. Demolition company lodges DA/CDC (if needed) or you organise it
4. Services disconnected (2–4 weeks)
5. Neighbours notified (council requirement)
6. Asbestos removal (if required) – usually 3–7 days
7. Demolition day – 1–5 days depending on house size

Questions and Answers: Common Questions About Demolition Companies in Sydney
Q: How long does house demolition take in Sydney?
Ans: Most standard single or double-storey houses are fully demolished and cleared in 3–10 working days once all approvals are in place. Tight access or large homes on the Northern Beaches can take longer.
Q: Do I need to be home when the house is demolished?
Ans: No. In fact most people prefer not to watch! The demolition company only needs access to the property.
Q: Will knocking my house down affect my neighbours in Sydney?
Ans: Good demolition companies minimise impact with dust screens, water sprays and vibration monitors. Sydney councils require neighbour notification letters before work starts.
Q: What happens to all the rubbish from my Sydney house demolition?
Ans: Around 90% gets recycled – bricks crushed for road base, timber chipped, metal sold. Only asbestos and a small amount of general waste goes to landfill.
Q: Can demolition companies remove my swimming pool at the same time?
Ans: Yes – most Sydney demolition companies also demolish and remove in-ground concrete pools and fill the hole ready for building.
