Estimated breakdown for your configuration
Any Australian home built before 1990 should be assumed to contain asbestos until an inspection says otherwise. A hazardous materials survey costs roughly $400 to $900 and is required by most councils and demolishers before work starts, so book it early rather than discovering the problem mid job.
Demolition quotes vary wildly on what they include. Insist that service disconnection, the hazardous materials survey, the council application, waste levies and site levelling are each shown as included or excluded, because those five items are where a cheap quote turns expensive.
Salvage has real value on older homes. Hardwood flooring, cast iron fittings, slate, bricks and even solid timber framing can be worth thousands to a salvage yard, and some demolishers will reduce their price for the right to strip the house before it comes down.
Ways to save
- Get the hazardous materials survey done before you seek quotes, not after you accept one. A survey costs $400 to $900 and tells every demolisher exactly what they are dealing with. Without it, contractors either price defensively with a large asbestos contingency built in, or they price low and hit you with a variation the day they find sheeting behind the eaves. The survey typically pays for itself several times over in quote accuracy.
- Strip out the soft demolition yourself if you have time. Removing carpet, curtains, cabinetry, appliances, non structural internal linings and fittings can reduce a demolisher's labour and waste volume noticeably, sometimes saving $2,000 to $5,000 on a standard house. Just stop at anything that could contain asbestos, which includes wall sheeting, eaves, vinyl backing and old adhesives.
- Sort the waste stream. Landfill levies in New South Wales and Victoria are among the highest in the country, and mixed skip waste is charged at the worst rate. A demolisher who separates clean concrete, brick, metal and clean timber pays substantially less at the gate and recovers scrap value on the steel. Ask contractors how they handle recycling, because the ones with a recycling process are often cheaper despite looking similar on paper.
- Combine the demolition with the earthworks for the new build. If a rebuild is planned, having the same contractor demolish, remove the slab, cut the pad and level the site avoids paying twice for mobilisation of an excavator and trucks, which is commonly $1,500 to $3,000 each time machinery comes and goes.

What a demolition costs in Perth
Demolishing a house in Perth is priced on the building's size, whether asbestos is present, the site access, and the material carted to tip, since a demolition is a machine knock-down followed by sorting and disposing of the debris. Asbestos is the sharpest cost, as an older home with asbestos needs licensed removal first, and the disposal is a real part of the figure, so the size, the asbestos and the disposal lead the cost.
Perth's common double-brick homes produce a large volume of heavy brick and concrete debris when demolished, which must be loaded and carted, and the masonry can often be crushed and recycled, affecting the disposal cost. Older homes carry asbestos in eaves, sheeting or fencing, removed by a licensed asbestos removalist before the knock-down. The sandy soils give easy machine access on a level block. The hot, dry climate is no factor for the demolition. The isolation of the WA market rarely changes a standard knock-down, labour sits near the national average.
