Mould, Moisture and Microbiology in Newcastle and the Hunter Valley
Independent mould and indoor air quality assessments to identify causes, assess health risks, and support effective remediation.
Why Mould and Moisture Problems Matter in Newcastle
In Newcastle and the Hunter Region, moisture problems and mould growth are common across both older homes and newer buildings — often linked to water ingress, inadequate ventilation, or construction defects. These issues are more than just a visual concern: they can damage structures, reduce indoor air quality, and affect occupant health.
Whether you're a homeowner experiencing recurring mould, a property manager dealing with tenant complaints, or a builder or insurer responding to water-related defects, we help you understand the root cause — and how to fix it the right way.
Our Services – End-to-End Mould & Moisture Investigation and Reporting
We provide comprehensive assessments and independent reporting to help you make informed decisions, meet compliance obligations, and return buildings to a safe, usable condition.
1. Moisture & Mould Investigations
Our process starts with a site-specific inspection. We combine visual assessment with tools like:
Thermal imaging
Moisture meters
Hygrometers
This allows us to locate active leaks, trapped moisture, and hidden mould growth. We also assess factors such as:
Ventilation design and usage
HVAC performance
Construction or waterproofing defects
Occupant behaviour contributing to damp conditions
Our aim is to trace the problem to its source, not just identify symptoms.
2. Mould Sampling & Lab Testing
If needed, we conduct surface, air, or bulk material sampling to identify:
Mould type (e.g. Cladosporium, Aspergillus, Stachybotrys)
Spore concentrations
Potential health implications
All testing is completed by NATA-accredited laboratories, and we interpret the results in line with industry guidance and relevant health literature. You’ll receive a clear explanation of what was found, whether remediation is required, and how urgently it should be addressed.
3. Remediation Scopes & Oversight
If remediation is needed, we prepare an independent, detailed scope of works, including:
Required control measures and PPE
Safe work procedures
Clearance criteria
Recommended contractor qualifications
We can also oversee the remediation process to ensure it aligns with the scope, and carry out post-remediation verification (PRV) with clearance inspections and optional air testing to confirm the site is safe to occupy.
Common Situations We Investigate in Newcastle

Frequently Asked Questions (FAQ) – Mould, Moisture & Microbial Consulting
Q: How do I know if mould in my building is a health risk?
Mould affects people differently, but exposure can lead to respiratory issues, asthma flare-ups, fatigue, eye or skin irritation, and worsened allergies — especially for children, the elderly, or anyone with a compromised immune system. Even if the mould is not visible, a musty smell, water stains, or damp areas may indicate microbial growth. We assess both the visible impact and airborne spore levels to determine whether health risks are likely.
Q: What causes mould to form in new buildings?
Mould in new builds is usually caused by construction moisture — such as trapped water from poor drying during the build, inadequate ventilation, wet plasterboard, or leaking windows and flashings. If not addressed early, mould can grow inside wall cavities, ceilings, or under floors. We investigate moisture intrusion at the building envelope level and provide recommendations to fix root causes, not just symptoms.
Q: Can you tell me if mould remediation was done properly?
Yes. We provide post-remediation verification (PRV) services, which involve a detailed inspection of the treated areas, moisture testing, and (where required) air or surface sampling to confirm that mould has been successfully removed and no longer poses a health risk. We can issue a clearance report that satisfies landlords, insurers, or regulatory authorities.
Q: Do you provide mould cleaning or removal services?
No — and that’s a good thing. We are independent consultants, not contractors or product sellers. That means you can trust us to give unbiased advice about what needs to be done and whether remediation is even required. If it is, we can refer you to experienced professionals and oversee the work to ensure it’s done correctly.
Q: Do I need to test the air for mould?
Air testing can help assess hidden mould contamination or airborne spore levels, especially in buildings with health complaints or poor ventilation. However, testing isn’t always necessary. We only recommend laboratory analysis when it adds value — and we always explain the purpose, cost, and benefit before collecting samples.
Q: What areas do you service?
We work across Sydney, the Central Coast, Newcastle, Lake Macquarie, the Hunter Valley, and regional NSW. We regularly assist property managers, homeowners, insurers, builders, and government agencies in both metro and rural areas. For large projects or urgent assessments, we can often attend site within 24–48 hours.
