Choose the right scope

Explain whether the test is for a purchase, rental management or a specific concern. Agree an appropriate testing approach before booking.

Understand the testing method

Ask who collects samples, whether laboratory analysis is included and what the report will cover.

Plan the next step

Ask how results and limitations will be explained, and whether further assessment may be required.

A building inspection does not establish whether a property is free of methamphetamine residue. Testing is a separate service with an agreed scope.

Understand the deliverable

Read the method alongside the result.

A useful testing report connects the sampling record, laboratory findings where applicable, and the explanation of what the results mean for the agreed purpose.

Sampling record

The collection date, collector, areas and sample references, with photographs or a location record where included.

Method and results

The test method, any laboratory report, reported units and relevant detection or reporting limits.

Interpretation and next steps

An explanation tied to the method and intended use, including limitations and any recommended further testing.

What does “below the detection limit” mean?

It describes the method’s reporting capability for the tested sample. It should not be read as proof that no residue exists anywhere in the property, or substituted for the applicable interpretation criteria.

What should I ask about composite sampling?

Ask which areas were represented, how the samples were combined, how the result is interpreted and whether it can identify the location of any residue. Further location-specific testing may be needed depending on the method and findings.

This is a guide to report contents, not a test result or laboratory certificate. The exact method and interpretation must be confirmed with the provider.

Before you book

Make the right choice for your property.

Useful answers without the jargon.

When is this useful?

When a purchase, property-management concern or known history raises a testing question. Explain the reason for testing so the provider can discuss an appropriate scope.

What should I confirm before booking?

The sampling approach, areas to be sampled, who collects samples, laboratory involvement, reporting format and the use you intend to make of the results.

What can the results tell me?

Results relate to the agreed samples, method and areas tested. Ask how limits, interpretation and any need for further testing will be explained. Do not treat a visual building report as a test result.

How do I prepare?

Discuss access and any known property history with the provider. Ask for method-specific preparation instructions before cleaning or altering the areas intended for sampling.

What happens if further action is recommended?

Ask the provider to explain the recommended investigation and who is qualified to undertake it. Testing and decontamination are distinct tasks; agree any follow-up separately.

Your local inspector confirms the actual service inclusions and arrangements.
