House Demolition in Sydney

Demolition starts with a plan, not a machine

On a city block, most of the work happens before the excavator arrives. We look at the site, the neighbours, the street and the approvals, then set the order of work. A clear sequence keeps the job safe, keeps neighbours informed and stops small problems turning into delays.

A typical house demolition runs like this:

• Approval confirmed, either a Complying Development Certificate or a development consent from council
• Hazardous materials survey of the house
• Dilapidation reports on neighbouring properties
• Service disconnections and a Before You Dig Australia check
• Asbestos removed and a clearance certificate issued
• Soft strip of fittings, then the structure taken down
• Footings, slabs and driveways broken out, and the block levelled

Approvals: CDC or DA

In NSW, a house demolition is either Complying Development or needs a Development Application. A Complying Development Certificate can be issued by council or a registered certifier under the Exempt and Complying Development Codes SEPP when the property meets the standards. Heritage items, and many homes in heritage conservation areas, usually need a DA instead. Across the Inner West, Woollahra, Hunters Hill and Ku-ring-gai that is common, so we check the planning controls early and work to the conditions of whichever approval applies.

Hazardous materials survey

Homes built before 1990 may contain asbestos in fibro sheeting, eaves, wet-area linings, vinyl floor backing, roofing and old flues. Older houses can also hold lead paint and synthetic mineral fibre insulation. A hazardous materials survey identifies what is there and where, so it can be removed before the structure comes down. Demolishing over asbestos is not an option.

Neighbours and dilapidation reports

Many Sydney houses sit a metre or two from the next building. Some share a wall with it. Before work starts, we arrange dilapidation reports on the neighbouring properties. Each report records existing cracks, finishes and fences with photos, so there is a clear baseline if a question comes up later. Neighbours are told when work starts, what the noisy stages are and who to speak to on site.

Services and site safety

Electricity is disconnected through the distributor (Ausgrid across the inner, eastern and northern areas), water and sewer through Sydney Water, and gas through Jemena. Telecommunications are disconnected as well. A Before You Dig Australia check is done before any excavation, so buried assets are located before footings and slabs come out. The site is fenced, signed and secured before demolition begins.

Access on tight blocks

Plenty of Sydney homes have no side access at all. The machine may need to come through the front, over a retaining wall or from a rear lane. We size the plant to the block, which can mean a smaller excavator, hand demolition near boundaries and more truck movements with smaller loads. Where a skip, work zone or truck needs council land, we apply for the permits under the council's kerbside rules before the start date.

Traffic, pedestrians and the street

Narrow streets, school zones, bus routes and parked cars all affect how trucks get in and out. For sites that need it, a traffic and pedestrian management plan sets truck timing, spotters, footpath protection and any closures. On busy streets that plan is often the difference between a smooth week and a stalled one.

Dust and noise control

Dust is kept down with water as the structure comes apart, and loads are covered before they leave. Noisy work is kept to the hours set in the approval conditions. Machines are not left idling, and the noisiest stages are flagged to neighbours in advance.

Taking the house down

Once the house is stripped of fittings and hazardous materials, the structure comes down in a controlled order, roof first and then walls, working away from neighbours where possible. Brick, concrete, timber and metal are separated as they come out so they can go to recycling rather than landfill. Footings, slabs, paths and driveways are broken out, and the block is left level and ready for the builder, surveyor or geotechnical engineer.

What to send us

Send the address, a few photos of the front, back and sides, and any approval documents or plans you already have. If you know roughly when the house was built, include that too. We will come back with questions about access and timing, then a written quote.
