Cost guide · Ceiling insulation · Brisbane & SE Queensland · 2026
Ceiling insulation cost in Brisbane, and why R3.0 does most of the work.
Pump-in Cellulose Fibre Insulation runs $38.50 to $60.50 per square metre including GST, supplied and installed. Polyester batts run $30.80 to $49.50 per square metre including GST. Where you land depends on ceiling size, roof access, what’s already up there and travel.
I’m Peter Johnson. I’ve been in South-East Queensland roofs for 40 years and we make the cellulose ourselves at Tiaro. Here’s what a ceiling actually costs, what moves the price, and the part nobody in this trade wants to tell you: why paying for a bigger R-value usually buys you almost nothing.

What a ceiling costs in 2026
The bands, in plain numbers.
Pump-in Cellulose Fibre Insulation runs $38.50 to $60.50 per square metre including GST, supplied and installed. If you’d rather have batts, polyester runs $30.80 to $49.50 per square metre including GST. Every price on this site includes GST, so there’s nothing to add on the end.
I don’t publish one flat total, because two houses with the same floor area can come in hundreds of dollars apart once access is in the mix. What I will do is give you a fixed price before anyone climbs into your roof, and not move it on the day.
There’s no fibreglass figure on this page because we don’t install fibreglass, and I won’t quote a product I wouldn’t put in my own house. If you want to know why, that reasoning is set out on why we use cellulose. For everything else about roof insulation in Brisbane — the roof types we work in, how we get into them, and who actually does the job — start there.
Cellulose Fibre Insulation
$38.50–$60.50 /m²
including GST · supplied and installed
Pumped in as one seamless blanket with no gaps. Made by us at Tiaro. Transferable Life-of-House guarantee.
Polyester batts
$30.80–$49.50 /m²
including GST · supplied and installed
Australian-made, no glass fibre. If you want batts, this is the one I’d put in.
Small jobs carry a minimum charge, because a half-hour of pumping still costs a day of truck, machine and travel. Ask me and I’ll tell you straight whether your job is under it.

What you’re actually buying: cellulose going in through the hose as one continuous blanket, with no cut edges to leave gaps.
What’s in the price
- A fixed price, quoted before we start
- No deposit, and no inspection to book first
- Measured off aerial imagery, not guessed
- Photographed before you're invoiced
- Transferable Life-of-House guarantee
Why two houses the same size aren't the same price
Four things that move your number.
None of these are surprises I spring on you at the door. They're all worked out before you get the quote.
The size of your ceiling
The biggest single number, and the one thing I can work out before I ever speak to you. I measure your roof off aerial imagery, so the square metres in your quote are the square metres on your house, not a guess off the phone.
How hard the roof is to work in
A low-set with a decent manhole and standing room is the cheap end. A cut-up two-storey, a low-pitch roof where the eaves close down under 400 mm, or a Clip-Lock deck with no easy way in, all cost more because they take longer and take it out of the installer.
Whether there's already something up there
Pumping over sound old batts is cheaper than clearing a roof out first. If what's up there is rodent-fouled, wet or falling apart, removal is its own job with its own price, and I'll quote it separately so you can see what you're paying for.
How far I have to come
We run out of Tiaro and across South-East Queensland. Travel is real and it goes on the quote as its own line rather than getting buried in the rate.
Travel gets its own line on your quote. I’d rather you saw it than had it buried in the rate and wondered why a Tiaro mob was dearer per metre than the bloke down your street.
The bit that costs me money to tell you
Is a higher R-value worth the extra? Usually not.
Every insulation salesman in the country would rather sell you an R5 than an R3. Here's a paper from our files that explains why I won't.
This is “The Diminishing Benefit of Extra Home Insulation”, written by James Fricker M.AIRAH and dated 7 February 2002. He modelled a Brisbane home with air conditioning and worked out the yearly cooling cost at each roof R-value. The shape of what he found is the whole point.
| Going from | To | Cuts the modelled cooling bill by |
|---|---|---|
| A bare roof | R3.0 | More than half |
| R3.0 | R5.0 | About another 16% |
Fricker’s own closing line is the one I’d put on the wall: “Extra R does not necessarily mean extra comfort or substantially more energy cost savings or greenhouse gas reductions.”
That’s why we install R3.0 as standard in Brisbane. The National Construction Code asks for about R2.5 in climate zone 2, so R3.0 puts you comfortably over it, and it sits right where the curve flattens off. Toowoomba and the Downs are zone 5, where R3.0 is the code figure itself. Work out yours on the R-value lookup.
Those dollar figures are 2002 prices
The dollar figures in Fricker’s table are 2002 energy prices and I’m not going to pretend they’re your bill today. Power has gone up a long way since. What survives is the shape: the saving is steep up to about R3 and then goes nearly flat, and that’s physics rather than pricing. The percentages above are worked out from his own table.
And there’s a catch that matters more than the R number on the bag. A rated R5 with gaps in it performs nothing like an R5. Coverage beats rating every time, which is the real reason a seamless R3.0 is worth more to you than a gappy R5.
Both pages of the paper as we hold it. The Brisbane cooling model is on the first, the Melbourne heating model on the second. We’ve blacked out the author’s email address and the name of the person it was faxed to.
The other big fork in the price
Top up over the old stuff, or clear it out first?
This is usually the difference between a straightforward job and a two-part one, so it's worth understanding before you compare quotes.
Pump straight over the top
If the old batts are dry, sound and nothing has been living in them, this is the cheaper and usually the better answer. Cellulose flows over and around them and fills the gaps at the joists, the edges and around the fittings, which is exactly where a batt ceiling was losing its R-value in the first place. You keep what you already paid for and fix what was wrong with it.
Clear it out first
Some roofs need emptying before anything goes back in: rodent mess through the batts, anything that’s been wet, or old insulation that has broken down to the point it’s just debris. That’s its own job with its own price and I’ll quote it as a separate line rather than folding it in. What removal actually involves.
You don’t have to work out which one you need. I look at what’s in the roof and tell you, and if it’s the cheaper answer I’ll say so. Talking a customer into a removal they didn’t need is how you get one job instead of a reputation.
The quote that costs you twice
Why the cheapest quote can be the dearest ceiling.
Insulation is invisible the moment the manhole shuts. You can’t see a gap, you can’t see a ceiling blown thinner than the R-value on the invoice. And you won’t know either way for twenty years. That’s what makes a cheap number risky in this trade, more than in most.
Paid by the metre
A subbie on a square-metre rate is rewarded for speed, not for dragging insulation out to the hard corners where it matters most.
No photos, no proof
If nobody photographs the finished roof, nobody can show you what you bought. Ours are checked before you're invoiced.
A price that moves
A number that goes up on the day isn't a quote, it's an opening offer. Ours is fixed before anyone climbs up there.
Straight answers
Ceiling insulation cost: the questions I get asked most.
How much does ceiling insulation cost in Brisbane?+
As a guide, pump-in Cellulose Fibre Insulation runs $38.50 to $60.50 per square metre including GST, supplied and installed. Polyester batts run $30.80 to $49.50 per square metre including GST if you'd rather have batts. Every price on this site includes GST, so there's nothing to add on the end. Where you land in that band depends on the size of your ceiling, how hard the roof is to work in, whether anything has to come out first, and how far we travel. I don't publish one flat total because two houses with the same floor area can be hundreds of dollars apart once access is in the mix. Send me your address and I'll measure your roof off aerial imagery and email you a fixed price, usually within 48 hours, with no deposit and no inspection needed first.
What R-value do I need for a Brisbane ceiling?+
Brisbane sits in climate zone 2, where the National Construction Code asks for about R2.5 in the ceiling. We install R3.0 as standard, which puts you roughly 20 per cent over the minimum. Toowoomba and the Darling Downs are colder, in zone 5, where R3.0 is the code figure rather than the buffer. The honest part most people don't get told is that pushing well past that buys you very little. The savings curve is steep up to about R3 and then goes nearly flat, so the difference between R3 and R5 is small money on your bill for a lot more money on the quote.
Is it cheaper to pump over my old batts or take them out first?+
Pumping over is cheaper, and if the batts are dry, sound and free of rodent mess it's usually what I'd recommend. Cellulose fills every gap around and over them, which is where an old batt job leaks its R-value anyway. Taking them out is a separate job with its own price. It's the right call when the roof is fouled with droppings, when something has been wet, or when the batts have gone to pieces. I'll tell you which one your roof needs, and I'll quote them separately so you can see the difference rather than getting one number with everything hidden inside it.
Are there government rebates for ceiling insulation in Queensland?+
No. There's no general Queensland or federal rebate a homeowner can claim for putting insulation in a ceiling right now. Victoria has a scheme, which is why you'll find Australian pages talking about rebates that turn out not to apply here. If that changes I'll say so on this page. I'd rather tell you there's nothing than have you chase a rebate that doesn't exist.
Why do you charge more than the cheap quote I got?+
Because the cheap quote usually leaves things out that you only find out about later. Ours is a fixed price quoted before we start and it doesn't move on the day. We make the Cellulose Fibre Insulation ourselves at Tiaro, so you're not paying a middleman on the material. The job is done by a trained owner-operator rather than whoever was cheapest that week, it gets photographed before you're invoiced, and it carries a transferable Life-of-House guarantee. None of that shows up in a headline number. All of it shows up in your roof.
How long does ceiling insulation take to install?+
Most houses are a one-day job. Pumping is quick because there's nothing to cut and fit; I run the hose from the manhole and fill the ceiling as one continuous blanket. A removal beforehand adds time, and a difficult roof adds time. If your job is going to need more than a day I'll tell you that in the quote rather than on the morning.
Do I have to pay a deposit?+
No. There's no deposit on our quotes, and no pre-quote inspection to arrange either. You send your address, I measure the roof off aerial imagery. And you get a fixed price by email, usually inside 48 hours. You pay when the job is done and the photos are checked.
Want a real number for your ceiling?
Send me your address, and I’ll price it properly.
No deposit, no inspection to book, and no salesman in your lounge room. I measure your roof off aerial imagery and email you a fixed price, usually within 48 hours. If your job needs something out of the ordinary, that’s in the quote too, not sprung on you on the day.
