Only a NATA-accredited laboratory can confirm the presence of asbestos. We are not that laboratory, and we do not take samples ourselves. We refer you to a licensed asbestos assessor, who collects the sample safely and sends it to an accredited laboratory for analysis.
That distinction matters. Anyone offering an instant on-site “result” is giving you an opinion, not an analysis, and an opinion is not something you can hand to a builder, an insurer or a purchaser.
Why you cannot tell by looking
Asbestos cement and modern fibre cement can look identical once they are painted, weathered or installed. Age is a strong indicator — Australian manufacture and use was not banned outright until 31 December 2003, and residential asbestos-cement products were largely phased out through the 1980s — but “built in 1975” tells you the odds, not the answer. Renovations muddy it further: plenty of Sydney houses have 1960s sheeting in one room and 1995 fibre cement in the next.
Experienced removalists develop a good eye for it. A good eye is still a guess.
What the laboratory actually does
The sample is analysed under AS 4964-2004, the Australian Standard for qualitative identification of asbestos in bulk samples. In practice that means stereo microscopy to separate out the fibres, then polarised light microscopy with dispersion staining to identify them by optical properties — which is what distinguishes chrysotile, amosite and crocidolite from the organic and synthetic mineral fibres used in modern products.
The result comes back as a written report identifying which asbestos types were detected, or that none were. That report is the document that satisfies a builder, a certifier or an insurer. Our name is not on the finding; the accredited laboratory’s is.
Why a professional takes the sample
Taking a sample means deliberately breaking a small piece off something you suspect contains asbestos. Done casually, that single act creates the exposure the test was meant to help you avoid — and it is the step that goes wrong most often in DIY testing.
A sample is collected under controls: the area wetted down, the piece taken rather than snapped, the sample sealed, and the sampling point sealed behind it. We do not publish the method, because this is not a job to attempt from a web page.
Home test kits sold online still require the sample to be taken by you and posted to a lab. The laboratory step is fine. The step before it is the problem.
What happens with each result
- Negative. You get the report and you carry on. That is a good outcome and it happens regularly.
- Positive, material intact and undisturbed. Removal is not automatically the right answer. Managing it in place is often safer and cheaper — an asbestos inspection will tell you which, and put it in a register if the property is a workplace.
- Positive, material damaged or in the way of work. We quote the removal. You are under no obligation to use us for it, and the laboratory report is yours either way.
If you are trying to work out whether it is worth testing at all, start with what asbestos looks like — and in the meantime, leave the material alone.
