Illicit Drug Residue Cleaning

Illicit Drug Residue Cleaning & Decontamination

Gloved hands disinfecting a contaminated surface — Testing comes first. Every job starts by establishing exactly what is present before any cleaning begins.

Illicit drug residue contamination is not limited to methamphetamine. Properties can carry residue from a range of substances, from imported drugs used residentially through to the precursor chemicals associated with clandestine manufacture, and each carries its own testing and handling considerations. Delta Environmental provides testing and decontamination across the full range of illicit substances we are asked about, with methamphetamine remaining by far the most common contamination we are called out for across Australia.

As with every service we provide, the process starts with independent testing, not assumption. A visual inspection alone cannot tell you which substance is present or how far it has spread, and different substances can call for different cleaning agents, contact times and disposal handling. We identify what is actually present before recommending a scope of work.

Our most common call-out

Methamphetamine: Our Primary Focus

Methamphetamine residue accounts for the large majority of illicit drug decontamination work we carry out across Australia, whether from residential smoking use, tenant manufacture, or a property with an undisclosed history. Residue from meth use and manufacture soaks into plasterboard, carpet, curtains, insulation and ductwork, often remaining invisible and odourless within weeks of exposure, which is why independent laboratory testing rather than a visual check is essential before buying, renting or continuing to occupy a suspect property.

Given how frequently we are asked about this specific substance, we maintain a full dedicated page covering our meth testing, decontamination and independent clearance process in detail, including typical timeframes, the clearance benchmark used across the industry, and answers to the questions we hear most often.

Beyond meth

Other Substances We Test & Decontaminate For

Cocaine

Cocaine is typically imported rather than manufactured domestically, so the large-scale clan lab contamination pattern seen with meth is less common. Residential use can still leave detectable residue on surfaces, and we test and clean affected areas the same way we would for any other substance.

Fentanyl

As a synthetic opioid, fentanyl requires specialised handling protocols given its potency, even in small residual quantities. Our technicians follow strict PPE and containment procedures for any suspected opioid contamination, and testing confirms exactly what is present before cleaning begins.

MDMA

MDMA residue is most commonly associated with residential use rather than large-scale local manufacture, though pill-pressing operations do occur. We test and decontaminate affected surfaces using the same independently verified process applied to any other substance.

Amphetamines

Illicit amphetamine, commonly known as speed, can leave a similar residue pattern to methamphetamine in properties used for regular consumption, and is tested and treated using the same surface sampling and decontamination approach.

Ephedrine & Pseudoephedrine

These are precursor chemicals associated with clandestine methamphetamine manufacture rather than substances typically consumed on their own. Properties where precursor chemicals have been stored or processed require the same independent testing and full decontamination as a meth manufacture site.

Specialised Opioid & Stimulant Residue

Beyond the substances above, our technicians are equipped to test for and decontaminate residue from a broader range of opioids and stimulants on a case-by-case basis. If you are unsure what a property may have been exposed to, independent testing is the starting point regardless of the substance suspected.

How it works

Our Drug Residue Decontamination Process

Independent testing. Accredited laboratory testing identifies which substance is present and how far contamination has spread.

Scope and quote. Test results inform a clear, itemised decontamination plan specific to the substance involved.

Containment & decontamination. The area is sealed and treated using methods and PPE appropriate to the substance identified.

Independent clearance. Post-remediation testing by an independent laboratory confirms the property is safe before reoccupation.

Why choose Delta

One Team, Every Substance

Not limited to meth

While meth is our most common call-out, our testing and decontamination process applies to a wide range of illicit substances.

Independent verification, always

Every result, for every substance, is confirmed by an accredited laboratory with no stake in the outcome.

Substance-appropriate methods

Cleaning agents, contact times and PPE are matched to the specific substance identified, not a one-size-fits-all approach.

Discreet and confidential

These situations are sensitive. We work discreetly and treat every job with confidentiality.

Not sure what you're dealing with?

You do not need to know which substance is involved before calling us. Independent testing is always the first step, and it will tell us exactly what we are dealing with regardless of the starting assumption.

Our guarantee

What You Can Expect When You Book Delta

Booking your property with an unfamiliar company can feel like a leap of faith, so we keep our side of the arrangement simple and transparent. You get a clear, itemised scope of works before anything begins, a fixed appointment window rather than a vague all-day slot, and a single point of contact for the life of the job rather than being passed between call centres.

If a job turns out to be larger or more complex once work is underway, we explain why, put any change in writing, and get your sign-off before proceeding. There are no surprise line items on the final invoice.

Straightforward, no-pressure quotes

We quote based on what your property actually needs, not a one-size-fits-all package. If a lighter touch will do the job safely, that is what we will recommend.

Good to know

Frequently asked questions

No. While methamphetamine is by far our most common call-out, we test for and decontaminate residue from a range of illicit substances, including cocaine, fentanyl, MDMA, amphetamines and precursor chemicals like ephedrine and pseudoephedrine.

You do not need to know beforehand. Independent laboratory testing identifies the specific substance and the extent of contamination before any decontamination work begins.

Fentanyl is far more potent by weight than most other substances, so we follow stricter handling and PPE protocols for any suspected opioid contamination, even though the property itself is treated with the same independent testing and clearance process.

They are precursor chemicals commonly associated with clandestine methamphetamine manufacture. Properties where these chemicals were stored or processed require the same independent testing and decontamination as a confirmed meth manufacture site.

Cost depends on the substance involved, the extent of contamination, and which materials need replacing versus cleaning. We provide a free, itemised quote once independent testing confirms the scope of the job.

We would not recommend it. Different substances require different cleaning agents and contact times, and disturbing contaminated material without the right protective equipment and testing can expose you to health risks. Independent testing and professional decontamination is the safer path.

Yes. Pre-purchase and pre-tenancy testing for illicit substance residue is one of our most common requests, particularly in areas with a known history of drug-related occupancy.
