Small job, big variable
Garage and shed removal is the least complicated demolition work we quote. One structure, usually a day or less on site, a machine and a truck.
There is exactly one thing that changes it from simple to serious, and in the Illawarra it changes it often: fibro.
The fibro shed problem
Post-war Illawarra back yards were filled with asbestos cement structures — sheds, lean-tos, garages, carport infills, and fencing. A great many of them are still standing across Warrawong, Cringila, Berkeley, Unanderra, Port Kembla and the older escarpment suburbs, quietly holding a mower and a few tins of paint.
Asbestos cement is difficult to identify by eye and is easily confused with later fibre-cement products that contain none. So the answer is testing, not opinion. If asbestos is confirmed, the removal is carried out by a separately licensed asbestos removalist — not by a demolition crew and not by you on a Saturday. The asbestos page explains why the sequence matters.
This is the single most common place we see homeowners about to do something genuinely unwise. Taking a hammer to a fibro shed spreads material across the yard the house next door shares, and it is one of the few DIY jobs that can create a problem you cannot clean up yourself.
Structure types and what they involve
Colorbond and steel-frame sheds. Straightforward. Dismantled or pulled down, steel separated for recycling, which offsets some of the disposal cost.
Timber-framed sheds and lean-tos. Also straightforward, though older ones sometimes have fibro linings behind timber cladding — worth checking rather than assuming.
Brick and masonry garages. Heavier, more spoil, and the disposal weight is the main cost driver. Clean brick and masonry can go to a concrete stream at a better rate than mixed waste if it is separated.
Fibro garages and sheds. Survey first. Licensed removal. Then demolition.
Carports and awnings. Usually the simplest, with the caveat that anything attached to the house needs the connection made good afterwards — ask whether that is in the scope.
The slab question
Almost every garage or shed sits on a slab, and whether it goes is a decision worth making deliberately.
Take it out if you are building anything there, if you want lawn or garden, or if the area needs to drain. A slab left in place under turf produces a permanently poor patch of grass and a drainage problem after rain.
Leave it if you want a hardstand for parking, a base for a new shed of similar footprint, or a paved area.
The economics are simple: removing the slab while the excavator is already on the block costs a fraction of bringing one back later. See concrete removal for how slab work is priced.
Empty it first
The one piece of preparation that saves real money on a shed or garage removal is emptying it properly beforehand.
A structure full of paint tins, old chemicals, tyres, batteries and general accumulation is not a demolition job — it is a demolition job plus a waste sorting job, and several of those items cannot go into a general bin at all. Paint, solvents, oils, gas bottles and batteries each have their own disposal pathway.
Sorting it yourself over a weekend, with a trip to the local waste facility for the problem items, will almost always cost less than having it priced into the demolition. It also removes a category of surprise from the quote.
If there is material you are unsure about — unlabelled drums, old chemicals, anything that looks like it might be asbestos sheeting — leave it and flag it at the site assessment rather than handling it yourself.
Access
The same Illawarra constraint applies. A back-yard shed needs a machine in the back yard, and that means side access wide enough to take one. Narrow side paths through the older suburbs — Thirroul, Bulli, Corrimal, the tighter parts of Wollongong — can mean hand demolition and material carried out, which is slower and therefore dearer.
Newer estates around Dapto and Shellharbour rarely present a problem.
Approvals
Small outbuildings can often be removed without development consent, but this depends on the council, the zone, the size of the structure and whether any heritage control applies. Worth a check rather than an assumption — the approvals page sets out the general pathways.

Frequently asked questions
How much does it cost to remove a garage or shed?
As a 2026 planning guide, a small colorbond or timber shed on an accessible block commonly runs $1,500 to $4,000, and a single or double garage $3,000 to $8,000 with the slab removed. A fibro structure requiring licensed asbestos removal is priced separately and will be higher — the removal is specialised work with its own disposal pathway.
Should I remove the slab too?
It depends what is going there next. If you are building, the new structure will almost certainly need its own footings and the old slab is in the way. If you are putting down lawn or garden, a slab left in place means poor drainage and a permanently unhappy patch of grass. Removing it while the machine is already on site is far cheaper than coming back.
My shed is fibro. What happens?
It gets tested before anything is touched. Fibro sheds across the Illawarra frequently contain asbestos cement sheeting, and dismantling one without knowing spreads material across your yard. If asbestos is confirmed, removal goes to a separately licensed asbestos removalist, and the structure comes down only after that work is completed and cleared.
Do I need council approval to demolish a shed?
Often a small, non-heritage outbuilding can be removed without development consent, but this varies by council, by zone and by the size and nature of the structure — and heritage listings or conservation areas change it. It is worth a check with your council rather than an assumption, and the contractor can tell you what is typical for that area.
