Drug Residue Testing Services

Drug residue testing is not typically included in a standard building inspection. However, if there are suspicions of drug use or manufacturing, conducting drug residue testing can be considered for safety and habitability. At Clear View, we offer reliable and thorough drug residue testing services to ensure your property remains free from any remnants of illicit drugs. We strongly advise conducting a proper test before purchasing or occupying a new property.

The Australian Institute of Criminology study found that about 75% of detected drug laboratories in Australia are located in residential properties. These properties can be found in various neighbourhoods, including affluent areas. Chemicals used in drug manufacturing during illicit production can become airborne and deposit on surfaces within the property, such as countertops, tiles, walls, ceilings, HVAC systems, septic systems, floors, carpets and pipes. Therefore thorough examination for traces of drug residue is necessary for premises previously used for narcotics purposes like meth labs (clan labs) and cannabis grow houses.

Australian homebuyers may find it surprising that approximately 2% of homes are impacted by methamphetamine residue. Many homeowners and residents may not be aware that they have been exposed to potentially harmful chemicals left behind from the production of meth.

Identifying Illicit Drugs in a Property

Drug residue testing is an important part of property inspections, especially for buildings tied to the manufacturing or cultivation of illicit drugs. This examination aims to identify any remaining drug residue that may pose dangers to its occupants.

Whether your property has a history as a “drug house” or you suspect drug-related activities, it’s crucial to undergo drug residue testing for awareness and specialized cleaning procedures aimed at removing potentially harmful toxins from the structure. Clear View Property Inspections can assist in identifying and addressing any drug residue concerns within your property.

The most common sources of drug contamination in a building include:

  • Meth labs (clan labs)
  • Meth smokehouses
  • Cannabis grow houses

According to the Australian Crime Commission (ACC), the illicit drug market in Australia is estimated to have an annual value of approximately $11 billion. One of the most commonly used and manufactured drugs is methamphetamine, also known as ice. The ACC has observed a rise in clandestine drug laboratories in recent years, with many focused on producing methamphetamine. These labs can leave behind dangerous residues that can linger on the property for extended periods if not adequately handled.

However, other illicit drugs may also have been previously present in a property in large quantities including:

  • Cocaine
  • Heroin
  • Fentanyl
  • Tetrahydrocannabinol (THC)
  • Cannabinol
  • Buprenorphine
  • Norbuprenorphine
  • Amphetamine
  • MDMA
  • Pseudoephedrine

Property Drug Residue Indicators

While an odour can detect some drugs like cannabis, many other potentially dangerous drugs are odourless and can be hard to detect by the naked eye.

  • Strong odours.
  • Discolouration around the property, including structures, soil, pavement or driveway.
  • Burnt, stained or yellowed walls and structures.
  • Rust in uncommon places like window fittings or door handles.

Property Examination

The initial examination of your property and its surroundings will provide important insight into the extent of drug residue and contamination in the building, as well as set expectations for the cleaning process. The inspector will use appropriate test kits and personal protective equipment to conduct a thorough examination without risk of exposure. If our findings are positive, the following steps should be taken.

Clean up Preparation

Now it’s time to prepare for clean up. Your inspector will assess the extent of the proposed cleaning based on their initial reports. The preparation will involve reviewing:

  • Contamination levels in each room and area
  • Necessary protective equipment
  • Cleaning machines required – Concerns regarding security or structural integrity
  • Waste disposal methods

Contamination Removal

The cleanup process starts by removing contaminated objects such as furniture and carpeting. In many cases, these items cannot be cleaned and must be discarded. After the contamination removal is finished, the property will be ventilated for at least another 24 hours. Drug residue testing plays a crucial role in ensuring the safety and well-being of individuals residing or working on a property.

Vacuuming Above-Ground Surfaces

A commercial-grade vacuum with specialized HEPA filters will clean all flooring, walls, and above-ground areas at this stage. This initial cleaning removes loose particles or debris from surfaces before deep cleaning begins.

Start the Deep Clean Process

We’ll also use specific high-quality cleaners known not to react with any drug residue. For instance, when cleaning a former meth lab, detergent cleaners are preferred over bleach as mixing bleach with meth creates a toxic gas, undermining the cleaning process.

Ventilation System

To check if the system has been contaminated, it will also undergo special testing. At this stage, the ducts will be disinfected using high-quality equipment to ensure a thorough cleaning and decontamination process once the HVAC system reboots.

Second Stage Cleaning

To ensure thorough cleaning, we use a safe cleaning agent and start with another wash of the property. We begin at the ceilings to prevent further contamination as any residue is released from higher levels. Then clean exhaust vents, light fittings, and hard surfaces several times in the final stages.


Drug residue from drugs like meth can make your plumbing system flammable, which is dangerous for obvious reasons. With professional drug residue testing, we’ll check your plumbing and septic systems to ensure the safety of your property.

Final Testing

Once the clean-up process is complete, your property will undergo final drug residue testing to ensure compliance with council laws. If the property fails this test, it will undergo another deep cleaning process. In extreme cases, walls and ceilings may need to be encapsulated with primer and paint to reduce residue levels to pass.

Property Inspections and Drug Residue

Drug residue testing is important due to the risk of drug residue to your health and its risks to your property. Drug residue testing is especially crucial when it comes to properties that have been involved in drug-related activities such as meth labs or marijuana cultivation. Drug residue testing is essential for a new property inspection as it helps identify and remove any unwanted chemicals or residues that may be present.

Residential Drug Residue Testing

Drug residue testing is crucial for safety and well-being. Our professional team conducts thorough inspections using top-of-the-line equipment, prioritizing customer satisfaction with meticulous attention to detail.

Illicit drug production in residential properties can cause significant harm to the structure and health hazards for occupants and neighbours. Therefore, property owners, landlords, and managers should proactively recognize these risks by conducting routine inspections, screening tenants thoroughly, and implementing drug residue assessments.

Drug Residue Inspection

Testing drug residues in properties has become a critical aspect of property inspections, particularly given the growing prevalence of drug use and clandestine drug laboratories. The issue has recently garnered considerable attention due to its potential health implications and legal ramifications.

Property inspections serve several purposes, such as ensuring occupant safety and welfare, assessing property value, and identifying possible hazards. Drug residue testing is an integral part of these inspections as it aids in detecting illicit substances’ presence while shedding light on their associated health risks.

During property inspections, evaluating for drug residues involves collecting samples from surfaces such as walls, floors, countertops, and furniture. Different methods can be used for this testing, including swabbing surfaces and analyzing the samples in a lab or using rapid on-site test strips.


The presence of methamphetamine residues in properties is a concerning issue, often associated with illicit drug manufacturing or use. Research studies have highlighted the potential health risks posed by these residues, especially for children who are more vulnerable due to their higher metabolism rates.

Recently, there has been increasing focus on developing rapid on-site test strips capable of detecting major drug residues like methamphetamine. These test methods are specifically designed for use outside the laboratory at inspection sites, providing immediate results and facilitating prompt decision-making regarding property safety.


The detection of ephedrine/pseudoephedrine residues in properties often signifies illicit drug activity, especially in the production of methamphetamine. It is crucial to test for these substances during property inspections to identify potential clandestine drug manufacturing operations and safeguard the safety of occupants and the local community.

The presence of ephedrine/pseudoephedrine residues in properties can be a significant concern. It may pose health risks and have legal implications, especially if not disclosed by property owners or potential buyers who are aware of their illegal drug manufacturing use.


Drug residue testing is crucial for property inspections, particularly in identifying the presence of 3,4-methylenedioxymethamphetamine known as ecstasy. This powerful stimulant and hallucinogenic substance can have serious health implications for individuals exposed to its remnants.

The detection of MDMA residues signals potential illegal drug use or distribution within a property, posing significant risks to the well-being of occupants both physically and mentally. Additionally, uncovering MDMA residues bears important legal considerations since possession and distribution of this illicit substance are prohibited acts in multiple jurisdictions.
