Demolition is usually the first big cost of a knock-down rebuild, so it pays to get it right. The cheapest quote is not always the cheapest job: a price that leaves out asbestos, the slab or the permit tends to grow once work starts. This guide covers practical ways to keep your residential demolition in Perth affordable, and the warning signs that a low price will cost you more.

8 ways to keep demolition costs down
1. Start the paperwork early
Permits and service disconnections take longer than the demolition itself. Starting early avoids paying for delays, rescheduled machinery or a builder waiting on a site that is not ready. Find out how demolition permits work in Perth.
2. Get the asbestos inspected before you compare quotes
Asbestos is the biggest unknown in an older Perth home. If it is identified at the start, every contractor can price the same scope and you avoid a surprise variation halfway through. Our guide to asbestos and demolition explains what to expect.
3. Clear out the house first
Remove furniture, rubbish, garden sheds full of belongings and anything you want to keep. Everything left inside becomes waste the contractor has to sort, cart and pay to tip.
4. Salvage what has value
Solid timber doors, leadlight windows, kitchen appliances, hot water systems and good-quality bricks can often be sold or reused. Agree with your contractor before work starts what you are keeping, so it can be removed safely.
5. Choose a contractor who recycles
The WA waste levy on Perth metro landfill is $90 per tonne from 1 July 2026 (WA Government). Separating concrete, brick, metal and green waste for recycling sends less to landfill, which keeps disposal costs down.
6. Bundle the extra work into one visit
If you also need trees removed, a pool filled or taken out, retaining walls removed or the block levelled, do it while the machinery is already on site. A second mobilisation costs more than doing it all at once.
7. Make access easy
Ask neighbours early about access along a shared boundary, move vehicles off the verge and trim overhanging branches if you can. Better access means less time and a lower price.
8. Compare like-for-like quotes
Line up each quote against the same list: permit, disconnections, asbestos, slab and footings, waste, clean-up, levelling and insurance. A quote that is $3,000 cheaper but leaves out the slab is not cheaper.
Red flags that make a cheap quote expensive
- No site visit. A price given over the phone cannot account for access, asbestos or the slab.
- No mention of a permit. Demolition without a permit risks fines and stop-work orders.
- No insurance details. Ask for proof of public liability insurance and workers’ compensation cover.
- Vague about waste. Ask where the waste goes. You want it recycled or taken to a licensed facility, not dumped.
- Asbestos “included” with no inspection. Licensed asbestos removal has real costs. If it is free, it probably is not being done properly.
How to check a demolition contractor
Demolition work in WA is generally licensed by WorkSafe under the Work Health and Safety (General) Regulations 2022, which set out Class 1 and Class 2 demolition licences (WA Government). You can check a licence with the online licence search, and you should ask any contractor for their licence details, insurance certificates and a written scope of work.
What affordable demolition should still include
Affordable does not mean bare minimum. A fair price for a house demolition in Perth should still cover a site inspection, the permit, coordinated disconnections, safe removal of the structure, waste removal and recycling, and a clean, level site handed back to you.
