Types of Mould Testing

Different testing methods provide different information. The right test depends on your situation, whether you need to identify species, measure airborne concentrations, or document conditions for legal purposes.

Air Quality Testing (Spore Trap)

The most common form of mould testing. A calibrated air pump draws a known volume of air through a collection cassette, capturing airborne mould spores. Samples are collected from multiple indoor locations and compared against an outdoor baseline sample.

  • Detects elevated spore levels indicating hidden mould
  • Compares indoor vs outdoor spore concentrations
  • Identifies mould genera present in the air
  • Results in 3-5 business days from lab

Surface Sampling (Tape Lift / Swab)

Physical samples collected directly from visible mould growth using adhesive tape lifts or cotton swabs. These samples are sent to a laboratory where a mycologist identifies the mould species under microscopy or through culture analysis.

  • Identifies exact mould species on surfaces
  • Determines if growth is Stachybotrys (toxic black mould)
  • Useful for health risk assessment
  • Essential for insurance and legal documentation

Bulk Material Sampling

Small pieces of contaminated building material (plasterboard, carpet, insulation) are removed and sent to the laboratory for analysis. This determines whether the material is contaminated and whether it can be cleaned or must be removed. Commonly used during remediation planning.

Post-Remediation Clearance Testing

After mould removal, clearance air testing verifies that spore levels have returned to normal background levels. This provides written evidence that the remediation was successful and the property is safe for reoccupation. Often required by insurers and property managers.

Mould Testing FAQs

Professional mould testing in Melbourne typically costs between $300 and $800, depending on the number of samples taken and the type of analysis required. Basic surface swab testing with lab analysis starts around $300-$400. Comprehensive air quality testing with multiple indoor and outdoor samples and full laboratory analysis is typically $500-$800. Prices are indicative only and will vary based on scope, access, location, and individual contractor pricing. Request free quotes for accurate pricing.
A mould inspection is a visual and instrument-based assessment of your property to locate mould and moisture sources. Mould testing involves collecting physical samples — either air samples or surface swabs — and sending them to a laboratory for analysis. Testing identifies the specific species of mould present and quantifies spore concentrations, which can be important for health assessments and determining the appropriate remediation approach. Many professionals offer both as a combined service.
Standard laboratory turnaround for mould testing is 3 to 5 business days from when the lab receives the samples. Some laboratories offer rush processing in 24-48 hours for an additional fee. The on-site sample collection typically takes 1 to 2 hours. Your testing professional will advise on expected timelines and can usually arrange expedited results if urgency is required.
The main types of mould testing are air sampling (spore trap analysis), surface sampling (tape lift or swab), bulk sampling (removing a piece of material for analysis), and dust sampling. Air sampling is the most common and measures airborne spore concentrations. Surface sampling identifies species growing on specific surfaces. The appropriate test type depends on your situation — your testing professional will recommend the best approach.
If mould is clearly visible, testing is not always necessary before starting remediation. However, testing is valuable when you need to identify the specific mould species for health risk assessment, when there are concerns about toxic mould such as Stachybotrys (black mould), when you need documentation for insurance or legal purposes, or when you want to verify that remediation was successful through post-removal clearance testing.
Air quality testing can detect elevated mould spore levels that indicate hidden mould growth even when none is visible. If indoor spore counts are significantly higher than outdoor baseline levels, this suggests active mould growth somewhere in the property. However, air testing alone cannot pinpoint the exact location of hidden mould — it needs to be combined with a physical inspection using moisture meters and thermal imaging to locate the source.
