If you suspect methamphetamine has been used/manufactured in your dwelling, the first step is to contact a reputable accredited testing company to ensure the best results are achieved.
There are a number of testing methods available, however, Lab-based testing provides us with the most accurate information which enables us to plan you decontamination/remediation work efficiently.
Getting the exact level of the contamination
Testing should be in conjunction with the New Zealand standard (NZS 8510:2017 Testing and decontamination of methamphetamine-contaminated properties). So it is important to obtain a copy of the test results to review after comprehensive testing has been completed to determine methamphetamine contamination.
A house can test positive for methamphetamine but be below the national standard. If the results are low enough no work may be required. However, if the results are over a speficified level (NZS 8510:2017) it is most likely the property needs to be decontaminated.
The types of testing results you are likely to receive from a testing company are: Field Composite, Lab Composite or Comprehensive. Different costs and reasons for this depending on the level of contamination.
