Mould, Moisture and Microbiology
Science-led mould and air quality investigations — helping you respond confidently to damage, complaints, and building issues
Why Mould and Moisture Problems Matter
Mould and dampness are more than cosmetic issues. Left untreated, they can damage building materials, trigger asthma and allergies, and compromise the safety of workplaces, rental properties, schools, and homes. Moisture intrusion is also a red flag for potential structural damage, poor ventilation, or defective construction.
Whether you’re a property manager facing tenant complaints, a builder dealing with water ingress, or a homeowner worried about your health — we help you understand what’s happening, why it matters, and what to do next.
Our Services – End-to-End Mould & Moisture Consulting
We offer comprehensive investigations and tailored reporting to help you meet compliance, make informed decisions, and restore healthy indoor environments.
Investigation & Assessment
Every project begins with a site-specific investigation. We conduct visual inspections, assess moisture loads, and use instruments like thermal imaging cameras, hygrometers, and moisture meters to identify where water is entering or accumulating — and whether mould growth is active or historical.
We also evaluate contributing factors such as ventilation, HVAC performance, construction defects, and occupant behaviours. The goal isn’t just to find mould — it’s to uncover the underlying moisture source and assess the extent of microbial impact.
Sampling & Laboratory Analysis
Where necessary, we collect samples for laboratory analysis to confirm mould types, concentrations, and potential health risks. This may include surface swabs, air sampling (spore traps or culture plates), or bulk material testing.
All samples are processed by NATA-accredited laboratories, with results interpreted in line with industry guidelines, research literature, and health standards. We help you understand whether remediation is warranted — and how urgent the issue may be.
Remediation Planning & Oversight
If mould remediation is required, we prepare a clear, site-specific remediation scope of works. This outlines the scope of works, safety requirements, containment measures, and clearance criteria — suitable for builders, insurance companies, hygienists, or cleaning contractors to follow.
We can also oversee remediation works to ensure they’re carried out in accordance with the plan. Afterward, we conduct post-remediation verification (PRV) including visual inspections, moisture checks, and clearance air sampling (if required) to confirm the site is safe to reoccupy.
Common Situations We Investigate
We regularly consult on:
Mould following flooding, leaks, or construction water ingress
Rental disputes involving tenant health complaints or repair delays
Insurance claims for water damage, burst pipes, or storm impacts
New builds where mould is appearing shortly after handover
Strata and body corporate concerns in shared building systems
Commercial or government sites where indoor air quality is under scrutiny
If it smells musty, looks damp, or is making people sick — we’re here to help.
Why Choose Confluence Environmental?
We are independent consultants — not affiliated with remediation companies or product vendors — which means you get honest, defensible advice. Our assessments are backed by scientific evidence, clear reporting, and practical recommendations that hold up under scrutiny from regulators, insurers, and certifiers.
With experience in WHS, hazardous materials, environmental health, and indoor air quality, we bring a broader risk lens to microbial issues — not just how to clean them up, but how to stop them from coming back.
Where We Work
We provide mould and microbiological consulting services across:
Sydney (all regions)
Central Coast
Newcastle & Lake Macquarie
Hunter Valley
South Coast, Mid North Coast, and regional NSW

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.
