How this page works
Every answer opens with the answer, then adds only the context that stops it misleading you. Dollar figures are Mandurah and Peel guide bands current at August 2026, explained fully on the costs page; permit and licensing answers summarise the WA rules covered in depth on the permits page.
Money
How much to demolish a house in Mandurah? $16,000–$27,000 for a single-storey brick-and-tile home, $23,000–$42,000 for a fibro-era house with licensed asbestos removal staged first, $28,000–$55,000 for two storeys — all including tip fees and a level block.
Pool removal? $6,500–$19,000 depending on method: collapse-and-backfill at the bottom of the band, full dig-out at the top.
Are tip fees in the quote? They should be, in writing. Disposal is one of the biggest cost lines in demolition, and quietly excluding it is the oldest trick in the cheap-quote playbook.
Permission
Shed demolition: small sheds and patios (up to about 40 m² in the City of Mandurah's guidance) generally escape the permit requirement; dwellings and larger structures need a BA5. Confirm your case with your council — Mandurah and Murray each have the final say inside their own boundaries.
Pools: a permit requirement usually exists in some form; the method (backfill versus full removal) changes what the council wants to see.
Your own hands: licensing attaches to the work class, not to ownership. High or multi-storey structural demolition is licensed-contractor territory with a five-working-day WorkSafe notice; everything else still carries full WHS, asbestos and permit obligations.
Timing
Knockdown-rebuild: six to twelve weeks from engagement to cleared block, dominated by utility abolishment and the permit — the machines themselves need only two to five days for a single-storey house.
Asbestos holds: sampling, licensed removal and clearance sit in front of demolition, not alongside it. Pre-1990 house? Build the hold into your program from day one.
Something we missed?
If your question is not on this page, it is probably about your block rather than the process — and blocks need eyes, not web pages. Call (08) 9516 2266, describe the structure, its age and the access, and the enquiry goes to an independent Peel-region contractor who can answer against the actual job. The suburbs covered are on the Mandurah & Peel page; what this site is and is not sits in the disclaimer.
Frequently asked questions
How much does it cost to demolish a house in Mandurah?
A standard single-storey brick-and-tile house in Mandurah costs $16,000 to $27,000 to demolish as at August 2026, with tip fees included and the block left level. A fibro or asbestos-era house runs $23,000 to $42,000 once licensed asbestos removal is staged in first, and a two-storey home $28,000 to $55,000. Access, the amount of concrete on the block and whether a pool or sheds come out in the same mobilisation decide where in the band a job lands.
Do I need council approval to demolish a shed in WA?
Often not for small ones — the City of Mandurah's guidance indicates sheds, patios and similar structures up to about 40 square metres can generally come down without a demolition permit, while anything larger, and any dwelling, needs a BA5 demolition permit before work starts. The Shire of Murray requires a demolition permit for buildings and structures more broadly. Because exemptions are applied by the council to your specific property, a quick call to building services before booking the work is the cheap way to be certain.
How long does a knockdown-rebuild take in Mandurah?
Allow six to twelve weeks from engaging a demolition contractor to standing on a cleared, level block — several weeks for utility abolishment (electricity is usually the slowest to finalise), around two to four weeks for the demolition permit, then two to five working days of actual demolition. The rebuild is a separate program with your builder, and most builders will not start site works until the block is cleared and the demolition signed off, so the demolition stage sits squarely on the critical path.
How long does the demolition itself take?
Two to five working days for a typical single-storey Mandurah house, from the first bite of the excavator to the last truck of rubble leaving. Two-storey homes, heavy accumulations of concrete hardstand, tight access and any asbestos hold extend that; a simple shed or garage is usually gone in a day. Most of the calendar time in a demolition project is consumed by approvals and disconnections before machines arrive, not by the knock-down itself.
Who disconnects power, gas and water before demolition?
The owner or their demolition contractor must arrange full abolishment — not just disconnection — of electricity with Western Power and gas with ATCO, plus capping of water and sewer with Water Corporation, before demolition can begin. Electricity abolishment is usually the item that takes longest to finalise, so it should be lodged first. The utilities bill their own charges direct to the owner, which is why these fees sit outside demolition quotes; a good quote states plainly who is lodging each application.
What happens if my house has asbestos?
Demolition pauses at that point: suspect material gets sampled, and confirmed asbestos of more than 10 square metres of bonded sheeting — or any friable material — must be removed by a WorkSafe WA licensed asbestos removalist and cleared before the excavator starts. In practice, any Mandurah home built before 1990 should be treated as containing asbestos until testing says otherwise, and councils ask about it on the demolition permit paperwork. This site connects enquiries with licensed third-party removalists and does not publish handling advice — asbestos is licensed work, never DIY.
Does removing a swimming pool need a permit in Mandurah?
Usually yes in some form, because an in-ground pool is a structure — but councils treat full removal and collapse-and-backfill differently, so confirm the requirement for your method with the City of Mandurah or Shire of Murray before work starts. As at August 2026, in-ground pool removal in Mandurah runs $6,500 to $19,000 depending on whether the shell is broken in and backfilled or dug out entirely. One genuine upside: once the pool is lawfully gone, the ongoing safety-barrier inspection obligations go with it.
Are tip fees included in a demolition quote?
In a properly written Mandurah demolition quote, yes — loading, cartage and disposal are built into the single figure, and they are one of the largest slices of it. It is also where thin quotes hide their gaps, so get it in writing that tip fees, cartage and site clean-up are included, and ask whether concrete and brick are being carted to recycling, which costs less per tonne than mixed landfill waste and shows up in the price you pay.
Do I need a demolition licence to knock down my own house?
You never need a licence to be the owner — licensing attaches to who performs the work. Under WA's WHS laws a WorkSafe WA demolition licence is required for the higher-risk classes, broadly structures 10 metres or more in height and structural demolition of multi-storey buildings, with WorkSafe notified at least five working days before licensed-class work begins. A routine single-storey house generally sits outside the licence classes, but WHS duties, asbestos rules and the council's BA5 permit still apply in full — which is why owner-driven demolition rarely saves what it appears to.
Does this website carry out demolition work?
No — Demolition Mandurah is a referral service. Calls to (08) 9516 2266 and form enquiries are passed to independent local demolition contractors serving Mandurah and the Peel region, and those contractors quote, contract and perform the work as their own businesses. The site's operator does no demolition and does not verify any contractor's licence or insurance, so check licence status with WorkSafe WA and sight a current insurance certificate before engaging anyone. The disclaimer page spells this out in full.
