Asbestos in Renovations: What Australian Homeowners Need to Know
If your home was built before 1990, assume asbestos could be somewhere in it, and plan your renovation around that before anyone picks up a hammer. Asbestos is only dangerous when it is disturbed, so the safest path is to find it, test it, and have it dealt with properly before demolition, sanding, drilling or cutting begins. That protects your family, your neighbours and your budget.
We build, extend and renovate homes across Melbourne, and asbestos comes up on a surprising number of our first site visits. It rarely derails a project when it is found early. It causes real trouble when it is found halfway through, with walls open and a trades schedule running. This guide explains what to look for, what the rules generally require, and how to keep a renovation on track.
TL;DR
Most Australian homes built before 1990 are likely to contain asbestos, and the older the house, the higher the odds.
You cannot identify asbestos by looking at it. Have a sample tested by an accredited laboratory, or treat the material as asbestos until proven otherwise.
Breaking, cutting, drilling, sanding or blasting asbestos materials releases fibres. Power tools, high-pressure water and compressed air are the classic mistakes.
Removal rules differ between states and territories. In Victoria, check with WorkSafe Victoria, and for anything beyond a small, simple job, use a licensed removalist.
The best time to deal with asbestos is during planning, before demolition, not after the walls are open.

Why asbestos and renovations are such a risky mix
Asbestos was used widely in Australian building materials until the mid-1980s, and it lingered in some products until the late 1980s and into the 1990s. The Australian Government’s health department notes that most houses built before 1990 contain it somewhere. Our country used a great deal of it, and that includes the weatherboard, fibro and brick-veneer homes that make up much of Melbourne’s older suburbs.
In good condition and left alone, most asbestos-containing material sits quietly. The problem starts the moment a renovation turns it into dust. A kitchen strip-out, a bathroom retile, a new window opening or a rear extension can all disturb materials that have been stable for fifty years.
The health stakes are serious. Safe Work Australia explains that breathing in asbestos fibres can lead to asbestosis, lung cancer and mesothelioma, and that symptoms usually take 20 to 30 years to appear. That long delay is exactly why people shrug it off. You feel fine the day you sand the old eaves, and the consequence arrives decades later.
Research from Australian health bodies has also pointed to home renovation as a major source of non-work exposure. Surveys of people with mesothelioma have found that major home renovations were the most common way people outside the trades were exposed. Many DIY renovators in a New South Wales study reported being exposed during their projects, and a notable share said their partners and children were exposed too. Asbestos dust travels on clothes, hair and shoes, so it does not stay in the room where the work happens.
Where asbestos hides in Australian homes
The general rule from state asbestos authorities is simple. Homes built before the mid-1980s are highly likely to contain asbestos products. Homes built between the mid-1980s and 1990 are likely to. After 1990, the chance drops sharply, though it is not zero for older materials that were stockpiled or reused.
There are two types worth understanding:
Bonded (non-friable) asbestos is mixed into a hard material like cement sheeting. It is firm and cannot be crumbled by hand when in good condition. Most of what you will find in a house is bonded.
Friable asbestos is loose, soft or crumbly, such as old insulation or sprayed coatings. It releases fibres easily and is a much higher risk. It must be handled by specialists.
Bonded material can become friable if it is badly weathered, broken, or attacked with the wrong tools, which is why “it’s only fibro” is never a reason to be casual.
Common locations inside the house
Asbestos regulators list a long set of places where it turns up. Inside a typical older home, check these:
Wall and ceiling sheeting in wet areas, including behind tiles
Splashbacks in kitchens and laundries
Lining behind floor and wall tiles
Vinyl sheet flooring, vinyl tiles and the paper underlay beneath them
Carpet underlay and adhesives
Insulation around hot water pipes, old heaters and fuse boxes
Eaves linings and ceiling panels
Textured or sprayed ceiling coatings
Bathrooms, laundries and kitchens are the usual danger zones because they are the rooms most homeowners want to gut first. If you are planning a bathroom or laundry rebuild, our guide to what a wet area renovation involves explains the process, and testing sheeting and tile bedding belongs at the very start of it.
Common locations outside the house
Outdoor structures are easy to forget, and they are often where people take the biggest risks, because it feels like “just a shed”. Asbestos has been found in:
Imitation brick and weatherboard-look cladding
Fibro sheds, garages and granny flats
Roof sheeting, gutters and downpipes
Fencing
Concrete formwork and old pipes
If your plans include a deck, a new fence, cladding or a backyard rebuild, work through an outdoor renovation checklist alongside your asbestos check, so old structures are assessed before they are pulled down or built against.
How to tell if a material contains asbestos
You cannot tell by looking. Two sheets of cement board can look identical, and only one contains asbestos. Age is a clue, not proof. The reliable options are these:
Get a sample tested. Accredited laboratories analyse small samples, and an asbestos assessor can take the sample safely for you. Do not scrape or snap a piece off yourself without guidance.
Assume it is asbestos. If testing is not practical, the official advice is to treat the material as if it contains asbestos and take the precautions that follow.
Commission an asbestos assessment. For a major renovation or demolition, an intrusive inspection by a licensed assessor looks inside wall cavities, under floors and above ceilings. That gives a far clearer picture of hidden material than a walk-through, and it is the step we recommend for any pre-1990 home.
A clean test result on one sheet does not clear the whole house. Houses are often patched and extended over decades, so a 1950s house may have 1970s additions with different materials. Test each distinct material you plan to disturb.
Before you start: a practical pre-renovation plan
The Asbestos Safety and Eradication Agency’s guidance for householders and renovators is clear on the order of play: get advice, test or assume, then plan your response. Here is how that looks in practice.
Step 1: Work out the age and history of the house
Check the build date, then look for evidence of earlier extensions or renovations. Previous owners may have left building records, and your council may hold permit history. Heritage homes need extra care, since they often have layers of repairs from different eras. We cover that in our piece on the top challenges of heritage renovations in Melbourne.
Step 2: Arrange testing before design is locked in
Testing early means the results can shape the design and the budget. If the sheeting behind your bathroom tiles turns out to contain asbestos, you want to know that before you finalise the scope. It also helps to set aside a contingency for surprises. Our article on renovation design briefs with a 10% contingency shows how to build that buffer in from day one.
Step 3: Decide who does the work
This is where the rules matter most (more on that below). For anything beyond a very small, simple job, a licensed removalist is the safer, and often not much more expensive, choice once you count the equipment, protective gear, waste disposal and your own time.
Step 4: Tell the people around you
Official guidance says to inform your neighbours before asbestos work begins. It is courteous, and it is practical too: they can close windows, bring in washing and keep children and pets away. It also heads off complaints that can stall a job.
Step 5: Plan where you will live
Living in a house during asbestos removal or major demolition is rarely wise. Dust management, air clearance and daily life do not mix easily. Our guide on staying in your home during a renovation in Melbourne goes through the tests we use to decide, including how asbestos affects the call.
Who can remove asbestos, and what are the rules?
In Australia, asbestos regulation sits with each state and territory, so the detail depends on where you live. Safe Work Australia is explicit that licensing requirements vary and that you should contact your state’s work health and safety regulator. In Victoria, that regulator is WorkSafe Victoria, and EPA Victoria also has a role in how waste is handled and disposed of.
There are some common themes across the country:
Small amounts of bonded asbestos. Several states allow homeowners to remove a limited area of non-friable asbestos, commonly 10 square metres or less, without a licence. Some jurisdictions, such as Queensland, add training or certificate requirements, and all of them expect safe methods. Do not assume the rule in one state applies in another.
Larger areas of bonded asbestos. These generally need a licensed removalist.
Friable asbestos. This always calls for a licensed specialist with the appropriate class of licence. It is never a DIY job.
Homeowner duties. Under public health laws and the common law duty of care, you are responsible for not releasing fibres in a way that could harm your family or neighbours.
The Asbestos Safety and Eradication Agency goes further than the legal minimum. It advises that using a professional is usually safer, often cheaper, and easier than doing it yourself. We agree. The legal line may say you can, but the practical question is whether you should.
What about builders and trades?
When a builder or trade business works on your home, it has its own legal duties. A business or undertaking carrying out work at a residential property must manage asbestos risks under work health and safety laws. In practice, that means identifying whether asbestos is present, assessing the risk, and controlling it before work starts. A builder who shrugs and says “we’ll deal with it if we find it” is not meeting that standard.
At Yorcon, we manage the whole build, from design through permits, approvals and construction. That includes raising asbestos early, arranging assessment and engaging licensed removalists where required, so you are not coordinating specialists on your own.
What to avoid when asbestos may be present
The Asbestos Safety and Eradication Agency lists the habits that turn a manageable material into an airborne hazard. Keep these off your site:
Power tools. Sanders, grinders, circular saws and drills create fine dust.
High-pressure water. Blasting an old fibro roof or fence is one of the most common DIY mistakes. It spreads fibres across the yard and into the drains.
Compressed air. Blowing dust off a surface just puts the fibres into the air.
Breaking sheets. Smashing or dropping cement sheet crumbles the bonded material.
Ordinary vacuum cleaners. Even a household vacuum with a HEPA filter is not suitable for asbestos dust. A purpose-built Class H vacuum is required.
Dumping waste in your general bin or skip. Asbestos waste must go to a licensed facility, double-wrapped and labelled as required.
What if you accidentally disturb asbestos?
It happens more than people admit: a tile lifts and reveals a crumbling board, or a sheet cracks during a demolition. Here is a calm, sensible response.
Stop work immediately. Turn off any power tools and fans.
Keep people and pets away. Leave the area, and close doors if you can do it without disturbing more dust.
Do not sweep or vacuum. Dry cleaning spreads the problem.
Avoid tracking dust through the house. Take off dusty clothes carefully and wash them separately from other laundry, and shower.
Call a licensed asbestos assessor or removalist. They can test the material, set up air monitoring where appropriate, clean up and issue clearance.
Contact your regulator if needed. If you are unsure about reporting or waste, WorkSafe Victoria and EPA Victoria are the starting points in Victoria.
If you are worried about exposure, speak to your GP and mention what happened, so it is on your record. A single brief exposure carries a small risk compared with repeated or heavy exposure, but no level is considered completely safe, so the aim is always to avoid it rather than hope for the best.
Asbestos, demolition and permits
Demolition is the point where asbestos is most likely to be released in bulk, which is why it is treated so strictly. Pulling down part of a house to make way for an extension, or flattening it for a rebuild, brings asbestos assessment, licensed removal and waste disposal into the schedule before the machinery arrives. Our article on whether you need a demolition permit in Melbourne covers the approvals side.
If you are considering a knockdown rebuild, asbestos removal is typically one of the earliest line items in the job. It is far better to price it before you commit than to meet it after the contract is signed. Structural work brings similar surprises, and our Melbourne structural renovation costs and permits guide helps you plan for them.
Selling or buying a home with asbestos
Yes, you can sell a house that contains asbestos in Australia. Asbestos in itself does not make a property unsaleable, and a great many older homes change hands with it still in place. What matters is honesty and process.
Disclosure rules differ between states and territories, and they can change, so we cannot give you one national answer. A few principles hold up broadly:
Sellers should not mislead buyers about what they know. If you are aware of asbestos, tell your conveyancer or agent and let them advise on how it should be disclosed in the contract.
Buyers can ask about asbestos, arrange a building inspection, and commission an asbestos assessment as part of their due diligence.
Insurers may treat asbestos differently, so check your policy before and during renovation work.
If you are buying an older home with renovation in mind, a pre-purchase assessment helps you price the real cost of the project. It is a smart move to get a clear picture of any asbestos before you sign, particularly if you intend to gut bathrooms, remove ceilings or knock out walls. For legal questions about your own contract, speak to a conveyancer or property lawyer in Victoria.
Renovating a heritage or older family home with asbestos
Older homes bring both charm and complications. A Victorian terrace may have original lime mortar, timber floors and decorative ceilings, but it may also have a 1960s bathroom extension out the back with fibro sheeting behind the tiles. A 1970s brick-veneer home may have asbestos in its eaves, its laundry and its vinyl floors.
The approach is the same in every case: identify, test, plan, remove what must go, and protect what should stay. For homes with period features, the aim is to deal with asbestos without damaging the details that make the house special. That takes a builder who understands both heritage fabric and hazardous materials, which is the work our heritage home renovation and restoration service is built around.
Families with young children should be especially careful. Our guide to child-friendly home renovation features looks at planning a renovation with kids in mind, and asbestos safety is the first thing to settle before any other design decision.
How asbestos affects cost and timing
Asbestos adds cost in three places: testing and assessment, licensed removal, and the extra time for approvals, clearance and waste disposal. The amount depends on the type of material, how much there is, how accessible it is, and whether it is bonded or friable. Quotes vary widely, so get written quotes from licensed removalists for your specific job.
What you can control is when you find out. Testing during planning lets you build removal into the budget and the schedule. Finding asbestos mid-build means stopping work, bringing in specialists and often paying trades to stand by. That is why we recommend assessing before design is finalised. If you want to see how asbestos sits within the larger picture, our family home renovation process guide walks through each stage in order.
Our architectural design service is priced at $15,000 to $35,000 as a one-off, and early investigation of existing conditions, including hazardous materials, is part of getting the design and the build budget right.
How Yorcon can help

If you are weighing up an older Melbourne home, our home renovations service covers the full project, and our free project feasibility call is a good first step. We will talk through your home’s age, what is likely to be hiding in it, and how that shapes your plans, with no pressure.
FAQ
How can you tell if it’s asbestos?
You can’t tell by sight. Age is a useful clue, since homes built before 1990 are likely to contain it, but only laboratory testing confirms it. An asbestos assessor can collect a sample safely. If testing isn’t possible, treat the material as asbestos and take full precautions.
Is a little bit of asbestos exposure okay?
No level of exposure is considered completely safe, though a single brief exposure carries a lower risk than repeated or heavy exposure. Because diseases like mesothelioma can take 20 to 30 years to appear, the aim is to avoid any exposure. If you think you have been exposed, mention it to your GP.
Can you sell a house with asbestos in Australia?
Yes, many older homes are sold with asbestos in place. Disclosure obligations vary between states and territories, so speak to your conveyancer or a property lawyer about what applies to your contract. Being upfront with buyers is always the safest approach.
What if I accidentally removed asbestos tiles or sheeting?
Stop work, keep people and pets away, and don’t sweep or vacuum the dust. Change and wash your clothes separately, then call a licensed asbestos assessor or removalist to test, clean up and clear the area. Mention the incident to your GP so it is on your record.
Can I remove asbestos myself during a renovation?
Some states allow homeowners to remove a small area of bonded asbestos without a licence, but the rules vary, and friable asbestos always needs a licensed removalist. In Victoria, check with WorkSafe Victoria first. Even where it is allowed, a licensed professional is usually the safer choice.
