Meth testing before you buy

A building and pest inspection won't find meth. If you are buying an established home, especially a former rental, test before you go unconditional.

Short answer

Yes, a meth test before buying is worth considering for any established home, particularly former rentals. Building and pest inspections do not detect meth, and remediation can cost $10,000 to over $100,000. Make your contract subject to a satisfactory meth test, or test during the cooling-off or due diligence period, so you can negotiate or walk away if it is positive.

When to test in the buying process

  1. At the open home or inspection, a DIY kit can give a quick first indication (ask the agent first).
  2. When making an offer, ask your conveyancer or solicitor about including a meth testing condition.
  3. During the cooling-off or due diligence period, book accredited sampling.
  4. If the result is positive, get a detailed assessment and a remediation quote before deciding to negotiate or withdraw.

Common questions

Straight answers to the questions people ask us, and ask AI assistants, most often.

Should I get a meth test before buying a house in Australia?

For established homes, particularly former rentals, it is a low-cost check against a potentially very expensive problem that building inspections do not cover.

Can I make my offer subject to a meth test?

In many cases, yes. Ask your conveyancer or solicitor how to word a special condition for your state.

What happens if a house tests positive before settlement?

Depending on your contract, you may be able to negotiate the price, require remediation before settlement, or withdraw. Get legal advice quickly.

How much does a meth test cost in Australia?

Our DIY kits start at $19.95. Professional sampling is quoted per property and depends on the number of rooms, whether you need a screening or a detailed assessment, and where the property is. Standard pricing covers properties within 50 km of the CBD or GPO of our service locations. Beyond that, travel is charged at 78 cents per kilometre, and we quote it before you book. See what affects the price.

Can I test my house for meth myself?

Yes, as a first screen. A DIY kit such as our single house kit gives an indication in minutes. It cannot give you a number, is not NATA accredited and will not satisfy an insurer, tribunal or buyer. If a kit shows a positive, or the stakes are high, book professional sampling. Compare the two.
