Asbestos and demolition: the pre-1990 reality

Here's the fact that shapes every demolition quote in regional Victoria: if your house was built before 1990, it almost certainly contains asbestos. Australia used asbestos cement products heavily from the 1940s until the late 1980s, and didn't ban asbestos outright until 31 December 2003. Demolishing around it isn't optional — it's the law, and it's the first thing a professional prices.

Where it hides in a typical regional home

• Fibro sheeting — external cladding on entire houses (the classic "fibro home"), plus sleep-outs and lean-tos.
• Eaves and gable linings — near-universal on 1950s–1980s homes, including brick ones.
• Wet areas — bathroom, laundry and kitchen wall sheeting ("Tilux" and similar), and vinyl floor tiles and their backing.
• Roofing — corrugated asbestos-cement roofs on houses, garages and dairies.
• The odd spots — flue pipes, fences, switchboard backing, under-heater pads, garden sheds.

Brick homes are not exempt: the eaves, infill panels and wet areas of a 1970s brick veneer are usually asbestos cement.

The rules in Victoria

• Asbestos must be identified before demolition begins — a pre-demolition asbestos survey by a competent assessor is the standard first step, and the building surveyor will expect it.
• Licensed removalists are required: a Class B licence covers bonded (non-friable) asbestos over 10 sqm; a Class A licence is required for any friable asbestos (damaged, fire-affected, or crumbling material, pipe lagging, low-density board).
• Removal happens first, as a separate stage — the machines don't start until the asbestos is stripped, wrapped and carted to a licensed disposal facility with the paperwork to prove it.
• Homeowners in Victoria may legally remove up to 10 sqm of bonded sheeting themselves — but for a demolition, don't: unlicensed removal contaminating a site can turn a $4,000 line item into a $40,000 remediation.

What it costs

• Licensed removal: $30–$150 per sqm of material, Victoria typically at the lower half of that band.
• Typical whole-house allowance: $2,500–$15,000 on top of demolition. A fully fibro-clad house sits at the top; a brick veneer with asbestos eaves and one wet area sits at the bottom.
• Testing: lab analysis of samples runs $25–$200 per sample; a pre-demolition survey a few hundred dollars.
• Disposal: roughly $13–$15 per sqm of sheeting at licensed facilities — asbestos can't go in ordinary demolition waste.

Era cheat sheet

• Pre-1940s: possible (some early sheeting), plus lead paint considerations.
• 1940s–1970s: assume it — often extensive. Fibro-clad houses of this era are effectively asbestos structures.
• 1970s–late 1980s: very likely in eaves, wet areas and sheds even on brick homes.
• 1990–2003: possible but uncommon — worth a survey, rarely a big cost.
• Post-2003: asbestos-free by law.

Bonded vs friable: why the distinction drives the price

Bonded (non-friable) asbestos — fibres locked in cement sheet — is the common case and the manageable one: sheets are wetted, unscrewed whole where possible, wrapped and carted. Friable asbestos — anything crumbling, fire-damaged, water-damaged, or naturally loose like pipe lagging and low-density board — releases fibres freely and jumps the job to a Class A removalist with enclosures, negative-pressure controls and air monitoring. This is why fire-damaged and long-derelict houses quote higher than their size suggests: the fire turned cheap bonded sheeting into expensive friable material. It's also why "she'll be right, it's only fibro" is the most expensive sentence in demolition — one crushed sheet under a machine track can convert a routine strip into a contaminated-site remediation.

What your neighbours should see

A professional asbestos stage looks reassuringly boring: signage up, area cordoned, suited operators hand-removing wetted sheets into plastic-lined transport, no dust, no smashing. If a demolition near you ever looks like asbestos-era cladding going through a machine dry, that's a WorkSafe call — for your own lungs' sake.

What a good contractor does

Surveys before quoting, names the licensed removalist, includes removal and disposal as a priced line item, and hands you the disposal dockets and clearance certificate afterwards. A quote that "excludes hazardous materials" on a 1960s house isn't cheaper — it just hasn't told you the real number yet. Our calculator builds an asbestos allowance from your home's era so the estimate you see is the honest shape of the job.
