House Demolition
Full knockdown of an existing house down to a cleared, level block, ready for your new build.

The garage the car hasn't seen in years. The lean-to holding up more spider webs than roof. The workshop a previous owner built in 1978 out of whatever was cheap — which, in 1978, meant asbestos cement sheet. Shed and garage demolition is the small-but-satisfying end of the trade: an eyesore off the block in a day, and usable ground where it stood.
The scope that matters: structure down, materials sorted and carted, and the concrete pad out — because a shed demolition that leaves the pad has just swapped one obstacle for a flatter one.
What the material is decides how the job runs
Modern steel sheds unbolt and come apart the way they went up, faster. Sheeting and frame go to metal recycling, which offsets a little of the cost. Half a day's work for most.
Timber-framed garages get pulled down and sorted — clean timber, steel, and general waste in separate loads to keep tip fees sensible.
Asbestos-era outbuildings are the ones that change the plan. Pre-1990 sheds and garages around Halls Head, Coodanup and the older parts of Mandurah routinely carry asbestos cement wall sheets or corrugated "super six" roofs. That material comes off first, as its own licensed stage, before the frame is touched — in WA, more than 10 m² of bonded sheeting is licensed removalist territory under the WHS (General) Regulations 2022. The referral process is on our asbestos removal page. It adds a step and a cost, and pretending otherwise is how corners get cut badly.
On Pinjarra and Ravenswood rural blocks, multiply all of the above: machinery sheds, stockyard shelters and decades of outbuildings often come down together as part of a broader site clearing job — one mobilisation across the whole block.
The pad comes out too
Under nearly every garage is 100 mm or so of concrete, and under older ones, footings as well. Breaking the pad out is quick while the excavator is already on site — a hammer attachment, a sorted load to the crushing yard, and the ground levelled behind it. Done separately later, the same work costs a second call-out. If the pad is large or connected to driveways and paths you also want gone, it's priced the same way as any concrete slab removal.
What goes in the shed's place shapes the finish: levelled and raked for lawn, or compacted properly if a new shed or slab is going down on the same footprint.
One visit, one number
A shed or garage demolition quote should name the structure, the sheeting material (tested if suspect), the pad, where the waste goes, and the finished state of the ground — fixed, in writing, tip fees included. Typical Mandurah prices for outbuildings sit at the lower end of the ranges on the costs page.
Call (08) 9516 2266, describe the shed — size, age, what it's made of — and we'll connect you with contractors who'll take it down properly, pad and all.

FAQs
Frequently asked questions
Do I need a permit to demolish a shed in Mandurah?
Usually not — under the Building Act 2011 (WA), demolishing sheds, patios and similar minor structures up to 40 square metres generally doesn't need a demolition permit. Bigger outbuildings, and anything on a heritage-listed property, are a different matter and should be checked with the City of Mandurah or Shire of Murray. The safest habit is to have the contractor confirm the permit position in the written quote — our permits page covers where the lines fall.
What about asbestos in old sheds and garages?
It's common. Garages and sheds built before 1990 around Mandurah frequently used asbestos cement sheeting for walls and 'super six' corrugated roofing, and that material must be removed before the structure is demolished — by a licensed removalist where the law requires it. In WA, removing more than 10 square metres of bonded asbestos sheeting needs a licensed contractor, and any friable material needs one regardless of amount. Suspect sheds get sampled before they get quoted.
Is it worth demolishing a shed myself?
A small modern steel garden shed, maybe. Anything with asbestos-era sheeting, a concrete pad, or real size to it is a different equation once you price safe removal, disposal fees, tip runs in a trailer, and your weekends. A contractor turns it into one visit: structure down, materials sorted, pad broken out, corner of the block levelled. Get the fixed price first and then decide — it's usually less than people expect, and the pad removal is the part DIY almost never finishes.
