Demolition is one of those industries where the marketing photos are meaningless. Everyone can post a tidy “before/after.” The difference you actually feel is in the boring stuff: licenses that match the work, insurance that’s genuinely active, safety systems that exist beyond a binder, and a scope that doesn’t quietly exclude half the job.
And if you only remember one thing, make it this:
A cheap demolition quote is often just an incomplete demolition quote.
A decision framework (not a vibe check)
Start by writing down what’s being removed, what’s staying, and what “done” means. Sounds basic. It isn’t. I’ve watched projects go sideways because the owner assumed “slab removed” meant “everything to natural ground,” while the contractor priced “cut to 300mm and cap services.” Both parties thought they were being clear.
You want a contractor who can do two things at the same time:
– Run a safe, compliant site
– Run a predictable schedule and cost plan
If they can’t explain their sequencing, disconnects, strip-out, hazardous checks, structural drop, load-out, cleanup, you’re not looking at a demolition contractor. You’re looking at someone with machines. Working with experienced Brisbane demolition contractors can help ensure the scope, safety requirements, and schedule are understood before work begins.
One-line reality check:
Clarity up front is cheaper than “variations” later.
Hot take: If they’re vague about licensing, walk away
I’m not being dramatic. In Brisbane (and broadly Queensland), you’re dealing with QBCC licensing and a web of requirements that change depending on what you’re demolishing, what’s on site, and what the site sits next to.
Ask for license numbers. Then verify them yourself.
A legitimate contractor won’t get defensive about that. They’ll expect it.
What I’d verify before a shovel hits the ground
Short list, because long lists get ignored:
– QBCC licence status and scope (does it cover your type of work?)
– Public liability insurance (certificate of currency, current dates)
– Workers’ compensation coverage
– High-risk work licences where relevant (rigging, dogging, EWP, etc.)
– Asbestos competency if there’s any chance it’s present (more on that below)
Now, this won’t apply to everyone, but if the contractor is “getting a mate in” for any of the above, you’re inheriting their risk. And your name is the one tied to the property.
Safety records: don’t accept theatre
Look, everyone claims “safety is our priority.” Fine. Prove it.
Ask for evidence that they manage safety, not just talk about it:
– incident / near-miss reporting examples (de-identified is fine)
– toolbox talk cadence and sample sign-on sheets
– plant inspection and maintenance logs
– sample SWMS and risk assessments that are clearly job-specific (not generic copy-paste)
Here’s the thing: a clean safety record doesn’t always mean a safe contractor. Sometimes it means they don’t report properly. I’ve seen that more than once.
One stat to anchor the conversation
Safe Work Australia reported 183 worker fatalities in 2023 (all industries), reinforcing why due diligence isn’t paperwork for paperwork’s sake. Source: Safe Work Australia, Key Work Health and Safety Statistics Australia 2024 (reporting 2023 data).
That’s not demolition-specific, but it’s a sober reminder: worksite risk is real, and systems matter.
Scope and specialization: your quote is only as good as your brief
Some demolition jobs are straightforward: small structure, clean access, no hazards, generous laydown area. Others are a mess: tight boundaries, live services nearby, partial demolition with retention, public footpaths, traffic control, noise constraints, cranky neighbours.
If you want apples-to-apples quotes, you need to define the job like you’re writing a recipe.
Scope details that actually change price and timeline
Not exhaustive, but these are the big levers:
– Access: Can a truck get in and out? Turning circle? Street occupancy?
– Constraints: Neighbouring structures, shared walls, overhead lines, easements
– Method: machine push, top-down, controlled dismantle, hand strip-out
– Material handling: salvage requirements, recycling targets, contamination risk
– End state: “site scraped” means nothing, specify level, compaction, slab removal depth, fence reinstatement, etc.
– Permits and authority notifications: who does what, and by when
If the contractor can’t repeat your scope back to you in plain language, they don’t understand it. And if they don’t understand it, they can’t price it.
Asbestos: treat it like it’s there until proven otherwise
Queensland has plenty of housing stock where asbestos is a reasonable assumption, not a surprise twist. If your building is older, don’t play roulette.
A professional contractor will either:
1) request an asbestos register / survey up front, or
2) price the job with clear asbestos exclusions and a discovery process
If neither happens, that’s a red flag.
Also: asbestos isn’t just “a removal line item.” It impacts sequencing, containment, air monitoring, disposal, and who can legally do the work. It changes everything.
Environmental practices (yes, this affects your budget)
Some clients treat recycling and environmental controls as “nice to have.” Then the disposal invoices land, and suddenly everyone cares.
Good demolition contractors plan environmental management from day one: dust, runoff, noise, waste streams. Not because it’s trendy, because it keeps regulators, neighbours, and schedules under control.
In practical terms, ask how they handle:
– dust suppression on dry days (water carts, misting, sealed loads)
– runoff and sediment control (especially on sloped sites)
– source separation (concrete vs metals vs timber vs mixed waste)
– tracking waste (weights, dockets, where it went)
Opinion, but I’ll stand by it: contractors who can’t explain their waste plan tend to be the ones whose “cheap” quote balloons once disposal starts.
Pricing and contracts: where most arguments are born
You want detail. Not a one-page number with “demolition lump sum” and a handshake.
A serious proposal breaks down costs and assumptions. It also names exclusions explicitly (rock, hidden footings, contaminated soil, asbestos, restricted access, after-hours noise limitations, traffic management, you name it).
What a “transparent” quote usually includes
– labour and plant (hours or allowances)
– permits / inspections / traffic control responsibilities
– waste disposal and recycling assumptions (with rates or allowances)
– site establishment, fencing, amenities
– service disconnect coordination (who arranges, who pays)
– contingency allowances and what triggers them
Then your contract needs the boring guardrails:
– milestone dates
– payment terms
– variation process (written approval, schedule impact stated)
– practical completion definition (what does “finished” mean on inspection day?)
If they dodge written change control, expect pain later.
Reputation and project management (the part nobody checks properly)
References matter, but you want recent ones, and ideally jobs that look like yours. A contractor who shines on open suburban blocks may struggle on tight inner-city sites with logistics and neighbour management.
Ask questions that make it hard to bluff:
– Did they hit the program? If not, why?
– How did they handle surprises?
– Were variations fair, documented, and priced before work continued?
– How clean was the site at handover?
– Did the supervisor stay consistent or rotate weekly?
Communication isn’t fluff here. It’s risk control.
Next steps that keep you out of trouble
If I were hiring tomorrow, I’d do this in order:
1) Site walk with the contractor’s supervisor (not just the salesperson).
2) Written scope confirmation and exclusions list.
3) License/insurance verification (independent check).
4) Waste plan and disposal assumptions reviewed.
5) Schedule with milestones and weather/access contingencies.
Then, and only then, sign.
Because once machines arrive, “we assumed…” becomes very expensive.
