If you own a fibro house in Sydney and you're planning to knock it down, there are two numbers you need to understand — the demolition cost and the asbestos removal cost — because every fibro house in Sydney needs both. Trying to separate them, or hoping to avoid one, is how homeowners end up with illegal jobs, SafeWork NSW fines and contaminated land. This guide is written by a licensed Sydney demolition contractor (NSW Demolition Licence AD214611, Asbestos Class B AD214613) and gives you realistic 2026 pricing based on jobs we quote and complete every week across Greater Sydney.
What Is Fibro — and Why It Matters
"Fibro" is Australian slang for fibre-cement sheet cladding. From the 1920s through to late 1987, almost all fibro manufactured in Australia (by James Hardie, CSR Wunderlich and others) was made with Portland cement bound together by chrysotile, amosite or crocidolite asbestos fibres. That's not scare-mongering — that's the material composition. The sheets were cheap, fireproof, waterproof and lightweight, which is why they were used on hundreds of thousands of post-war Sydney homes in suburbs like Mount Druitt, Blacktown, Penrith, Campbelltown, Bankstown, Punchbowl, Ryde, Dundas, Chester Hill, Guildford, Merrylands and across the Hills District.
Asbestos-containing fibro was only phased out between 1981 and 1987. James Hardie stopped using asbestos in flat sheet in 1987. If your fibro house was built or clad before 1987 — and the overwhelming majority of surviving Sydney fibro homes were — the sheeting, eaves linings, wet-area linings, backing boards behind kitchen cupboards, and often the roof itself must be treated as asbestos cement sheet (ACM) by law.
Fibro House Demolition Cost Sydney — Full Price Table
| Fibro house size | Floor area | Demo only | Asbestos component | All-in total |
|---|---|---|---|---|
| Small 2-bed cottage | 80–110m² | $18,000 – $24,000 | $5,000 – $8,000 | $23,000 – $32,000 |
| Average 3-bed fibro | 110–160m² | $22,000 – $29,000 | $6,500 – $10,000 | $28,500 – $39,000 |
| Large 3–4 bed with extensions | 160–220m² | $27,000 – $35,000 | $8,000 – $12,000 | $35,000 – $47,000 |
| Fibro + garage/granny flat | Add | + $3,000 – $7,000 | + $1,500 – $4,000 | Varies |
Prices are inc GST and include the licensed asbestos removal, SafeWork NSW notification, independent clearance certificate, mechanical demolition, debris removal, basic site levelling and the demolition completion certificate. They assume reasonable truck access and no in-ground pool. Slab removal is typically an additional $5,000–$12,000.
Why the Asbestos Line Item Is Not Optional
We get asked once a week: "Can't you just push it over and take it to the tip?" The short answer is no — and anyone who says yes is either unlicensed, uninsured, or planning to dump it illegally. Here's what the law actually says:
- The NSW Work Health and Safety Regulation 2017 requires any removal of more than 10m² of bonded asbestos to be done by a licensed Class B (or Class A) removalist. A 3-bedroom fibro house has 200m²+ of ACM.
- Bonded ACM must be removed by hand, intact where possible, double-wrapped in 200µm polythene or sealed in heavy-duty asbestos bags, labelled, and transported in a covered vehicle to a SafeWork NSW–approved facility (SUEZ Lucas Heights, Veolia Woodlawn, Bingo Patons Lane etc.).
- Mechanical demolition — the excavator with the grab — only starts after the asbestos is gone and an independent licensed asbestos assessor has signed a clearance certificate.
- SafeWork NSW must be notified a minimum of 5 clear working days before licensed removal begins.
The penalties for ignoring this fall on the landowner as well as the contractor. Illegal dumping of asbestos in NSW attracts fines up to $1 million for a corporation and $250,000 for an individual, plus clean-up costs. The cheap quote is not cheap.
The Process Step-by-Step
- Hazardous materials survey — A licensed assessor samples the fibro, eaves, vinyl tiles, backing boards and any suspect material. Lab-confirmed register produced. ($400–$900.)
- SafeWork NSW notification — We lodge the licensed asbestos removal notification online. Minimum 5 clear working days before work starts.
- Service disconnections — Power, gas, water, Telstra. We coordinate; you (or your builder) pay the utilities direct — allow $400–$1,200 each.
- Site setup — Perimeter fencing, signage, decon unit, negative-pressure where required, personal air monitoring.
- Licensed asbestos removal — Hand-strip all ACM. Double-wrap, label, load into covered skip. Typically 2–4 days for a standard fibro house.
- Clearance inspection — Independent licensed asbestos assessor inspects. Clearance certificate issued.
- Mechanical demolition — Excavator with grab/pulveriser attachment demolishes timber frame, roof trusses, slab (if included). Debris sorted and loaded out.
- Site handover — Clean, level pad. Demolition completion certificate, clearance certificate and tipping dockets provided to you in a project pack.
Total time on site for a standard fibro house: 7 to 12 working days from mobilisation to clean pad, assuming the 5-day SafeWork notification period has already run.
Fibro vs Brick vs Double-Brick — Cost Comparison
| House type (3-bed, ~150m²) | Demo only | Asbestos/hazmat | All-in | Time |
|---|---|---|---|---|
| Fibro cladding on timber frame | $22k – $29k | $6.5k – $10k | $28.5k – $39k | 7–12 days |
| Brick veneer (timber frame + brick skin) | $20k – $28k | $2k – $5k (eaves, vinyls) | $22k – $33k | 6–9 days |
| Double-brick / full masonry | $26k – $38k | $1.5k – $4k (if any) | $27.5k – $42k | 8–12 days |
Fibro is quick and cheap to break up because the structure is light timber — but the asbestos component more than makes up for the saving. Double-brick is the opposite: longer and heavier mechanical demo, but usually minimal hazardous material. If you've been quoted $12,000 to demolish a fibro house in Sydney, something is being left out — probably the asbestos.
Red Flags When Getting Fibro Demolition Quotes
These are the things we hear from homeowners who've just been burned by a cheap quote:
- "We'll just wrap it and knock it down." Illegal. Full stop. Walk away.
- "Asbestos is included in the price" — but there's no line item, no licence number, no notification lodgement, and no clearance certificate mentioned. The quote is hiding the fact they're not doing it properly.
- No NSW demolition licence number on the quote. Every legitimate Sydney demolition contractor has one — look it up on the SafeWork NSW public register.
- No Class B (or Class A) asbestos removal licence. If they're subcontracting the asbestos, who to? Get the subbie's licence number too.
- Cash discount offers. No insurance, no paperwork, no clearance certificate — and when the next owner tries to sell the land, the contamination comes back to you.
- Price is more than 20% below the next cheapest. Either they've missed something that will come back as a variation, or they're cutting corners you'll pay for later.
- No written itemised scope. If "slab", "asbestos", "tree", "disconnections" aren't each on their own line, you don't have a quote — you have a dispute waiting to happen.

Frequently Asked Questions
How much does it cost to demolish a fibro house in Sydney?
A typical Sydney fibro house costs $23,000 to $47,000 inc GST all-in — roughly $18,000–$35,000 for the demolition itself and $5,000–$12,000 for the licensed asbestos removal component. Price depends on house size, how much fibro cladding is present, interior asbestos (vinyl tiles, Zelemite, backing boards) and site access.
Does all fibro contain asbestos?
Any fibro installed in Australia before 1987 must be assumed to contain asbestos cement — it is not optional and it is not negotiable. In Sydney, 99% of original fibro homes still standing contain bonded asbestos. A lab sample test is cheap insurance if the age is uncertain.
Can a demolition contractor just wrap the fibro and knock it down?
No. "Wrap and crunch" is illegal in NSW. Bonded asbestos sheeting must be removed by hand by a licensed Class B (or Class A) asbestos removalist before mechanical demolition, double-wrapped in 200µm polythene, and disposed at a licensed facility. Anyone offering to "just push it over" is breaking the law and exposing you — the landowner — to prosecution and clean-up costs.
Do you need to notify SafeWork NSW before demolishing a fibro house?
Yes. Licensed removal of more than 10m² of bonded ACM requires 5 clear working days' notice to SafeWork NSW before work starts. Every fibro house in Sydney exceeds that threshold. Your contractor lodges the notification — ask to see the confirmation before work starts.
What is a clearance certificate and do I need one?
After the asbestos is removed and before mechanical demolition proceeds, an independent licensed asbestos assessor inspects the site and issues a clearance certificate confirming the area is safe. Keep it with your demolition certificate and tipping dockets — builders, certifiers and future purchasers may ask for it.
