How to Actually Read a Brisbane Demolition Quote

You get three demolition quotes back for the same old Queenslander. One's $18,000. One's $27,000. One's $41,000. Same house, same block, same job. So what's going on?

Most of the time, the price gap isn't really a price gap. It's a scope gap. One quote covers everything from asbestos testing to sewer capping to the final skip bin off site. The other covers "demolition" and hopes you don't ask what that includes until the invoice lands.

Reading a quote properly is the fastest way to stop paying for surprises. Here's what each part is actually doing.

The site inspection should come before the number

If a contractor gives you a firm price without walking the property, that's a signal on its own. Every Brisbane block has quirks that change the job: the tree canopy the truck has to squeeze under, the neighbour's fence that sits an inch inside your boundary, the concrete driveway that turns out to be reinforced with steel mesh, the soil that gets soupy after a wet week.

A proper inspection lets the contractor scope the work honestly. A quote written off a postcode and a photo is a guess dressed up as a number, and guesses tend to get topped up later.

The big line items you should see

Once you're looking at a real quote, the same handful of items show up on almost every one. Knowing what each covers makes it much easier to spot what's missing.

Labour and plant hire

This is the actual knocking-down part. Excavator time, operator, ground crew, ancillary equipment. It's often the biggest single line, but for older homes it isn't always the biggest total once the other items get added.

Asbestos testing and removal

For anything built roughly between the 1920s and the late 1980s, this line matters more than any other. Old Brisbane homes commonly have asbestos in the eaves, wall linings, roofing, and even the vinyl underlay, and Queensland law says only licensed removalists can touch it. On plenty of jobs, this single item costs more than the mechanical demolition itself.

If a quote skips asbestos entirely and your house is that vintage, ask why. Either they haven't tested yet, or they're leaving it out to look cheaper on paper.

Utility disconnections

Power, water, gas, sewer, telecommunications. Each utility has its own process and its own fee. Sewer capping in particular needs a licensed plumber and a Form 4 for council. Some quotes bundle these in, some list them as "by others," which is contractor-speak for you'll be arranging that yourself.

Council permits and approvals

Every demolition in Brisbane needs a private certifier and a Form 21 to close out. If your home is pre-1946 or sits inside a Character Residential zone or a Demolition Control Precinct, approvals get much harder and sometimes aren't granted at all. A good contractor flags this before you sign anything, not after.

Waste removal and disposal

Tip fees are charged by weight, and a demolished house weighs a lot. This line covers the trucks, the bins, and the gate fees at the waste facility. Contractors who separate recyclable materials on site (steel, concrete, clean timber) often bring this cost down, and the good ones will tell you how they handle it.

The extras that quietly push the total up

Two quotes can list the same headline items and still land thousands apart because of what's tucked into the fine print, or left out of it.

Access is the classic one. A house at the end of a narrow driveway, with power lines overhead or a slope down to the back fence, needs smaller machines and more manual work. That takes longer, and time is money on a demolition site.

Then there's what's under the house. Old concrete slabs, buried oil tanks, an ancient in-ground pool no one's used in a decade, tree stumps with root systems bigger than the tree they came from. If the quote doesn't mention them, either they've been checked and confirmed as included, or you're going to get a variation later.

Finally, look for the words "GST inclusive." A $22,000 quote and a $22,000 plus GST quote are two different quotes.

What a good quote actually looks like

The best quotes read like a scope of works, not a total with a signature line. You should see each item, what it covers, whether it's included or excluded, and a clear number next to it. Anything provisional should say so, with a plain-English trigger for when it kicks in.

You should also see who the contractor is: their QBCC licence, their asbestos removal licence if that's part of the job, their insurance details. In Queensland, unlicensed demolition work is a legal problem waiting to happen, and the paperwork is worth checking before the machinery shows up.

If you want to see what a properly itemised quote looks like in practice, contractors like Total Demolition Brisbane publish clear scopes for residential, commercial, and industrial jobs, which makes it easier to compare against whatever else is on your desk.

One last thing worth doing

Line up your quotes side by side and match them item for item, not total to total. Where one contractor lists something the others don't, that's a conversation to have. Sometimes it's a genuine cost the cheaper quote missed. Sometimes it's padding that shouldn't be there. Either way, you'll only find out by asking.

Demolition isn't a mystery. It's a sequence of specific tasks with specific costs, and any contractor worth hiring can talk you through theirs without getting cagey. The quote is your first look at how they work. If it's clear, itemised, and honest about what it doesn't cover, you're probably in good hands before a single wall comes down.
