What our clients are saying...

"The courses give a fantastic insight into not only the risks that methamphetamine poses to health but also enables contractors to understand what is required to get homes back to pre-loss condition. It is something which I believe needs to be taken seriously and the education which Decon Systems deliver will enable you to answer the questions clients/friends/family may have about the harsh reality of the drug. Isaac and Rosemary are both fantastic educators and will do everything they can before, during and after the course to ensure you have a good understanding of both testing and decontaminating methamphetamine."
