Mould can pose significant risks to both health and property if not addressed promptly and professionally. In New South Wales and Victoria, those responsible for a business or undertaking (PCBU) are required under WHS legislation to manage risks related to hazardous exposures, including those arising from mould contamination in workplaces, public buildings, and residential settings. Left unchecked, mould growth can compromise indoor air quality, trigger respiratory symptoms, and cause building damage. Recognising conducive environments for mould is crucial, as is identifying issues before they escalate.
A thorough mould inspection not only identifies visible growth but evaluates underlying or hidden contamination sources. According to the NSW Health guidelines:
Structured visual survey of rooms, air handling systems and susceptible surfaces
Air quality sampling for mould spores when health symptoms, odour, or high humidity are present
Surface sample collection (swabs/tape-lifts) to confirm contamination
Moisture mapping and detection for leaks or condensation in building fabric
Destructive (invasive) assessment, if hidden mould is suspected
Photographic documentation and laboratory analysis by an accredited facility
Tailored recommendations for remediation and further monitoring
Our risk-based approach provides various services, as advised by Better Health Channel Victoria and WorkSafe Queensland:
In-depth visual and moisture investigations
Air and surface sample analysis for spore count and species identification
Destructive testing where necessary to expose hidden contamination
Workplace risk assessments driven by PCBU duties under the Work Health and Safety Act
Insurance claim advice and documentation
Post-remediation verification for clearance certification
With accredited technicians trained to national and state standards, medical oversight, and detailed, regulator-ready reports, we provide:
Comprehensive initial inspection to diagnose surface and hidden contamination
Air and surface sampling tailored to the site circumstances and occupant health effects
Destructive testing for hard-to-access or high-risk areas
Detailed post-remediation verification with clearance certification
Support for insurance claims with tailored assessment documentation
Our approach integrates scientific methodology, regulatory awareness, and a practical understanding of building use—ensuring compliance with NSW and Victorian guidelines and best practice.
| Assessment Service | Purpose | When Required | Example Scenario |
|---|---|---|---|
| Visual Inspection | Identify obvious growth/risk | Initial investigation, visible damp/mould | New stains in office ceiling |
| Air Sampling for Mould | Assess indoor air quality, airborne spores | Health complaints, musty odours | Staff reporting persistent cough |
| Surface Mould Sampling | Detect contamination on materials | To confirm visible contamination or after cleaning | Wall cleaned but odour remains |
| Destructive/ Invasive Testing | Find hidden mould/moisture in structures | Recurring issues, failed basic remediation | Leaking windows repeatedly causing mould |
| Post Remediation Clearance | Verify remediation success, compliance | After clean-up, for insurance or tenancy | Required by landlord post-flood |
| Workplace Risk Assessment (PCBU focus) | Ensure legal compliance, staff safety | Any workplace with potential exposure or WHS requirements | Factory using water-based processes |
| Insurance Claim Assessment | Evidence for claims, dispute resolution | Following water damage, loss events or as requested by insurer | Hospital submits report for flood damage |
We provide professional mould assessment and testing in:

Documentation for workplace compliance, insurance, & regulatory authorities
| Section | Details |
|---|---|
| Industry / Site Type | Industrial Warehouse – Logistics Facility, Victoria |
| Issue Identified | Musty odours and visible mould patches near loading bays. Previous surface cleaning failed. Moisture ingress from roof condensation created a conducive environment for hidden mould growth behind wall insulation. |
| Impact on Operations | – Decreased indoor air quality and employee health concerns (respiratory irritation). – Potential workplace health & safety non-compliance under PCBU duties. – Risk of product contamination and insurance claim complications. |
| Audiometrics’ Involvement | Comprehensive mould assessment and testing conducted by Audiometrics, including: – Visual inspection across affected and adjacent areas. – Air and surface sampling to measure mould spore concentration. – Destructive testing within wall cavities to locate hidden moisture sources. – Detailed laboratory report with findings and remediation recommendations. – Post-remediation verification (mould clearance testing) to confirm remediation success. |
| Methodology / Techniques Used | – Air sampling (spore trap method). – Surface swab and tape lift sampling. – Moisture mapping and infrared thermography. – Data-driven mould identification and quantification per Australian standards. |
| Outcome | – Airborne mould spore levels reduced to safe background levels. – Full mould clearance certification achieved. – Warehouse operations resumed safely and compliantly. – Client engaged Audiometrics for periodic air quality and mould inspection services. |
| Keywords Integrated | mould assessment, mould inspection, air and surface sampling, destructive testing, post remediation verification, mould clearance certification, workplace mould testing |
Q: What is a professional mould assessment and does my site need one?
Professional assessment involves scientific investigation and sampling to identify sources, extent, and risks from mould – for example, a school reporting asthma incidents without visible mould benefited from air testing which found hidden duct contamination.
Q: When should a PCBU or property owner commission a mould inspection?
Arranging inspection is essential when health effects are reported but visible signs are unclear, after water damage, or after incomplete remediation works. Example: a workplace crew experienced musty odours and headaches, air sampling confirmed the need for remediation.
Q: What does a post-remediation clearance certificate mean?
It is formal confirmation by a competent party that remediation has returned the site to safe, acceptable standards—often needed for insurance or regulatory compliance post-remediation.
Q: What are typical signs of hidden mould?
Unexplained odours, localised damp or humidity, staining, and recurring health complaints such as sinus or skin irritation, even when no mould is visible.
Q: How do insurance claims benefit from detailed mould reports?
Insurers require specific, evidence-based documentation of both pre-existing conditions and work completed to approve claims – our reports include lab results, photographic evidence, and recommended next steps.
