Flipping a house with asbestos: the rules, the cost, the deal

Flipping a house with asbestos is a problem you inherit the moment you start buying the kind of house that flips well. The best cosmetic flips are tired, dated, under-loved homes, and in Australia that almost always means older homes, and older homes are where asbestos lives. It is not a reason to walk away from a deal. It is a reason to know what you are dealing with before you swing a hammer, because asbestos is cheap to manage when you plan for it and expensive, dangerous and occasionally illegal when you do not. Here is how I think about it on a flip.

This is general information, not safety, legal or health advice. Asbestos is regulated differently in every state and territory and the rules get updated, so confirm the current requirements with your state work health and safety regulator and use a licensed professional. When you are not sure whether something contains asbestos, treat it as though it does and do not touch it.

Why old flips and asbestos go together

The homes that make the best cosmetic flips are exactly the ones most likely to contain asbestos. Asbestos building products were phased out through the late 1980s and a full national ban took effect at the end of 2003. The federal agency responsible for it, the Asbestos and Silica Safety and Eradication Agency, says the safest assumption is that any home built before 1990 contains asbestos somewhere. It was used in more than 3,000 products, so this is not just a fibro-shack problem. Brick, weatherboard, clad and part-renovated homes from that era can all have it.

The timing matters more now than it used to. That material is decades old and deteriorating, and asbestos is most dangerous when it is damaged, weathered or disturbed. A run-down pre-1990 house, which is the classic flip target, is also the house most likely to have asbestos that has started to break down. So if you flip older stock in Australia, this is not an edge case you will occasionally meet. It is something to screen for on almost every deal.

Where asbestos hides in an older house

Before you can price it you have to know where to look. In a typical older Australian home, asbestos commonly turns up in internal wall and ceiling linings, external cladding and eaves, roof sheeting, and the wet-area sheeting behind bathrooms and laundries. It also hides in less obvious places: vinyl floor tiles and the backing under old lino, the flue and some drainage pipes, the backing board on the electrical meter box, and out in the yard in fences, sheds and carports.

The distinction that decides everything is friable versus non-friable.

• Non-friable (bonded) asbestos is the fibres locked into a solid material like fibro sheeting or asbestos-cement cladding. Left alone it is relatively stable. The danger comes when you cut, drill, sand or smash it, which is exactly what a renovation does.
• Friable asbestos is material that can be crumbled by hand when dry, like pipe lagging, sprayed coatings and loose-fill insulation. It releases fibres far more easily and is the serious, specialist end of the problem.

Most of what a flipper meets is bonded sheeting. But you do not get to guess, because the handling rules and the cost both hinge on which one it is.

Don't disturb it, and don't assume you can DIY it

The single rule that keeps you safe and legal is this: asbestos is a hazard when it is disturbed, so the work is tightly regulated and a lot of it is not yours to do. Here is the shape of the licensing, which runs off the harmonised work health and safety laws in most states:

• You can generally remove up to 10 square metres of non-friable (bonded) asbestos without a licence, as long as you follow the safe-handling procedures, but that is a ceiling, not a licence to rush.
• More than 10 square metres of bonded asbestos requires a licensed Class B asbestos removalist.
• Any amount of friable asbestos requires a licensed Class A removalist. There is no DIY version of friable work.

Two places change those rules. In the ACT, any asbestos removal at all requires a licence, so there is no unlicensed allowance. In Victoria, which runs its own occupational health and safety regulations, unlicensed removal is capped at 10 square metres of non-friable asbestos and no more than one hour of removal work in any seven-day period, with a separate tight limit on asbestos dust. Check the current figure with your state regulator before you rely on any of this, because these are the rules that get reformed.

Honestly, on a flip I do not DIY it even when the job sits under the threshold. A flip almost always involves cutting into more than 10 square metres of lining, your insurer and your resale disclosure care whether it was handled properly, and the testing, clearance and licensed disposal are a job for someone who does it every day. I get a licensed removalist, get the certificate, and spend my time on the parts of the reno that make money.

What asbestos removal actually costs on a flip

This is the number that matters for your feasibility, and it is also where a "cosmetic" flip quietly turns into something bigger if you did not see it coming. The figures below are indicative ranges pulled from licensed-removalist cost guides, and they vary a lot with volume, access, your state and what else is going on, so treat them as planning numbers and get real quotes.

• Bonded fibro removal runs roughly $40 to $150 per square metre, commonly $50 to $100, with a minimum call-out often around $1,500 to $3,000 for a small job.
• Friable asbestos costs about two to three times that, roughly $150 to $300 per square metre, because of the extra controls.
• A whole-house internal strip of bathroom, laundry and kitchen sheeting often lands somewhere around $3,000 to $6,000.
• An asbestos-cement roof is the big one, commonly $4,000 to $15,000 to remove, and more again if you are replacing it.
• Disposal is charged by weight, and fibro is heavy at roughly 11 to 16 kilograms a square metre. It has to go to a licensed facility. Putting asbestos in your household or skip bins is illegal.
• Friable work needs an independent clearance certificate before anyone re-enters, typically $400 to $2,000.

There is also a cheaper path worth knowing about. Where the material is intact and will not be disturbed, a licensed assessor may recommend encapsulation, sealing it with a protective coating rather than ripping it out. That can be the right call on, say, a sound asbestos-cement eave you are not touching. On a full reno it usually is not an option, but it is worth asking.

Whatever the path, these costs do not belong in your head, they belong in the budget. Put them through the renovation cost calculator with the rest of your scope so the removal is a line item, not a surprise.

How to handle asbestos when flipping a house

Put together, the way I run it on a deal is simple:

1. Assume, then confirm. If the house is pre-1990, get a licensed asbestos assessor to inspect and, where needed, take samples before you lock in your reno budget. Do not rely on your building and pest report for this: a standard building and pest inspection is a non-invasive visual check and does not test for asbestos.
2. Price it into the offer. Asbestos is a reno cost and a timeline cost, which means it belongs in your maximum offer, not in a pile of regret after settlement. A house full of it should be bought cheaper to compensate.
3. Remove or encapsulate with the right licence. Match the work to the licence class, bonded over 10 square metres to a Class B removalist, anything friable to a Class A, and do not let a cheap unlicensed quote tempt you into carrying the risk.
4. Clear and dispose properly. Get the clearance certificate where the work requires it, use a licensed tip, and keep every receipt. You will want that paper trail for your resale disclosure and your insurer.
5. Check the approvals and your cover. Removing a full asbestos roof or demolishing a fibro structure can trigger council or regulator notification, so confirm whether you need council approval for the work. And make sure your renovation insurance actually covers a site where asbestos is being handled.

Does asbestos kill the deal?

Almost never. On most flips it is a line in the budget and a few weeks in the timeline, not a reason to pass. The flippers who get hurt are the ones who found the asbestos after they had committed, when it was too late to adjust the price or the plan. Cost it, build the removal and clearance into your timeline so your holding costs carry it, and run the whole thing through a full analysis or at least a sample analysis with the asbestos work in the numbers.

Done that way, a fibro house at the right buy price with asbestos costed in can be a better flip than the already-renovated house next door, precisely because other buyers flinched at the fibro and you did not. The test is the same as every other deal in the how to flip a house in Australia playbook: the numbers have to work with the real costs in them. If the deal only pencils when you pretend the asbestos is not there, it is not your deal.

This is general information only and is not safety, legal, health or financial advice. Asbestos identification, removal, licensing, disposal and notification rules differ by state and territory and change over time. Always confirm the current requirements with your state work health and safety regulator and use a licensed asbestos assessor and removalist.
