Common Asbestos Removal Mistakes Property Owners Must Avoid
One in three Australian homes contains asbestos (Asbestos Safety and Eradication Agency). That figure should inform every renovation plan for an older Sydney property. Get the removal steps wrong and you risk a fine while releasing fibres that can lodge in lungs for decades and lead to asbestosis and mesothelioma.
Skipping the survey before demolition or renovation
Contractors walk onto jobs where someone has already knocked out half a laundry. There is dust on the floor, a pile of broken sheeting by the back door and no one knows what that sheeting was. It is the most common failure we see.
You have a duty to identify asbestos before you renovate or demolish. That duty is written into work health and safety rules. It applies whether you are renovating a bathroom yourself or hiring a crew to gut the place. If your home was built before the late 1980s, you should assume suspect material is present until testing says otherwise.
People look for fibro walls and stop there. Asbestos-containing materials show up in many other places. In Sydney homes we have found it in vinyl tiles and backing adhesives, as well as roof linings and pipe lagging. We have also found it in corrugated roofing and eave linings. It can turn up in insulation and wall cavities where you cannot see it without opening the lining.
Do not start demolition until you have a survey from a licensed asbestos assessor. The assessor will map suspect material across the property, and samples go to a NATA-accredited laboratory for confirmation. You receive a written record of what is asbestos and where it sits. That record then guides the entire removal plan.
Thinking you can spot asbestos by eye
Plenty of owners are sure they know asbestos when they see it. They tap a sheet, look at the pattern and decide it is safe. That confidence is misplaced.
You cannot confirm asbestos by eye. New fibre cement looks much like old asbestos cement once it is painted. Vinyl tiles from different years can look identical from above. Even experienced contractors will not make a firm call without lab work. Only analysis of a bulk sample can confirm whether fibres are present and what type they are.
A licensed assessor knows how to take that sample with fibre controls in place. The area is wetted first, then a small piece is cut with hand tools and sealed at once. The sample is bagged, labelled and sent to a NATA-accredited laboratory. The lab report removes the guesswork. If the result is positive, you treat the material as friable or non-friable according to its condition and plan the removal to match.
Do not rely on old paperwork either. A previous owner’s word or a building report that says ‘possible fibro’ is not a clearance. Materials degrade, and renovations can cover old layers with new ones. A fresh survey and current lab results are the only baseline you should trust before disturbing walls or floors.
Misjudging what DIY is allowed to cover
In New South Wales a property owner can remove up to 10 m² of bonded asbestos from their own property without a licence. That is the total for the job, not an allowance for each room. Once you go beyond that area, you need a contractor with a Class B licence for bonded material. Friable material requires a contractor with a Class A licence, no matter how small the patch is.
Most people hear 10 square metres and picture a big job. It is not. One garden shed wall can use most of the allowance, while two small bathroom walls will push you over. Friable material such as old pipe lagging or crumbling insulation is never suitable for DIY. If it crumbles under hand pressure, leave it alone.
There is a reason the limit is tight. Bonded sheets still release fibres when they crack or break. A DIY job with no enclosure or air control can expose the whole home. Any job beyond that allowance, or any bonded job you would rather not handle, is work for a licensed crew. A provider of Asbestos Removal Sydney services should hold the correct licence class and follow notification and disposal rules.
Asbestos Removal in Sydney is controlled work. The contractor notifies SafeWork NSW at least five days before licensed work starts. The crew follows a safe work method statement drawn from the national How to Safely Remove Asbestos Code of Practice. That paper trail protects you if neighbours raise questions or if you later sell the property.
Reaching for power tools
Power tools and asbestos are a bad mix. We have seen drill holes in eaves where someone hung a light, along with grinder cuts in fibro made for a new pipe. Each cut took seconds, but it also sent a cloud of respirable fibres into the air.
A power drill, angle grinder, circular saw or pressure washer will shatter bonded material at speed. Bonded asbestos is only safe while the cement matrix keeps the fibres locked in. High-speed blades and abrasive discs tear that matrix apart. A pressure washer has a similar effect on a roof because it blasts away the surface layer. Even brief work can create fibre levels you do not want to breathe.
The safer rule is to remove the material manually and in one piece. Wet the sheet first. Undo fasteners by hand, then lift the panel whole without breaking it. If a sheet is screwed tight, cut the screws rather than the sheet. Bag the waste at once so offcuts are not kicked around the site.
Leave the power leads coiled.
If you must make a penetration for cables or plumbing, stop and reassess. Even a small hole requires controls. In many Sydney homes it is cheaper to reroute the service than disturb the sheet.
Pulling material out dry
Dry removal is the fastest way to fill a room with fibres. We still hear about jobs where sheets were pried off dry and stacked in the yard, with no damp cloths or other controls. Dust hung in the sun, and anyone nearby breathed it in.
Wetting keeps fibres down. A fine water mist weighs down fibres so they cannot remain airborne. Crews add a small amount of surfactant to help the water soak in, and the material stays damp from the first spray to the bag. That single habit reduces airborne release far more effectively than trying to clean up afterwards.
You do not flood the sheet. You mist it and work in small areas so surfaces do not dry between steps. In hot weather, re-mist as you go. Our crews keep a garden sprayer nearby for touch-ups. The goal is to keep the material damp, not dripping, all the way to the bin.
Do not use a high-pressure hose for this step. High pressure strips the surface and drives fibres out. Use low pressure with a wide spray. If water runs off coloured, collect it rather than letting it flow into soil or drains, where it could dry and release fibres later.
Wearing the wrong protection and spreading dust
A paper dust mask will not stop asbestos fibres. Neither will a cloth covering or a surgical mask from the chemist. Fibres are much finer than ordinary dust, so without a proper seal and filter, they pass straight through.
Anyone near removal work needs a properly fitted P1 or P2 respirator. This requires a clean-shaven fit and a seal check each time. Disposable coveralls and gloves are also needed, while boot covers keep dust away from laces and soles. Used coveralls are bagged as asbestos waste rather than shaken out for reuse.
Fibres cling to clothes, boots, tools and hair. If you walk from the work zone to the kitchen for a drink, you carry them with you. Children and pets can then pick them up from floors and furniture. A small bathroom job can contaminate an entire home this way.
The work area must be isolated before any sheet is moved. Crews cover walls and floors with 200-micron plastic and tape the joins shut. They close doors and switch off fans that could push air through the home. Only the removal team enters the area, and tools remain inside until they have been wiped down and bagged.
Do not eat or drink in the work zone. Do not bring household vacuum cleaners into it unless they have HEPA filters rated for asbestos work. Standard household vacuums blow fine fibres back into the room. Change out of your coveralls before stepping beyond the plastic.
Bagging waste wrong and using the wrong bin
Asbestos waste cannot go in a normal bin or a household skip destined for general landfill. It also cannot sit uncovered on a trailer during the trip to the tip. Each of these actions is illegal and risks releasing fibres on the road.
Waste must be double-wrapped in sealed and labelled 200-micron plastic bags. Sheets too large for bags are wrapped in plastic sheeting of the same thickness and taped shut. Every package receives an asbestos warning label. Sharp edges need extra wrapping so they cannot puncture the plastic during handling or transport.
Transport is only part of the job. Disposal must take place at an EPA-licensed waste facility set up to accept asbestos. The driver books in and unloads the waste in the marked cell. Tip receipts remain with the job file. Without those dockets, you cannot prove lawful disposal if questions arise later.
Penalties for illegal dumping are harsh. Councils can order cleanup at your cost.
You still carry the liability if someone else dumps the waste for you. Bona fide contractors therefore provide licence numbers and tip dockets without needing to be prompted.
Skipping air monitoring and hiring on price
Once removal is complete, the area must be checked by someone independent. A licensed asbestos assessor inspects the zone and often conducts air monitoring with HEPA-filtered pumps. Filters go to a laboratory for fibre counts. If the area passes the visual inspection and air results, the assessor issues a clearance certificate. You need that document before anyone sleeps in the room or uses it as living space.
Do not hire on price alone. A lawful contractor holds an active SafeWork NSW Class A or Class B licence, with the licence number shown on the quote. Mates-rates crews may skip notification and clearance, leaving you with the risk. Ask for proof of the licence and previous clearance documents. If they stall, walk away.
Every mistake above has a compliant fix. Test first and use licensed workers for anything beyond the small DIY limit. Keep the material wet and sealed, then keep the paperwork in order.
