Have we really moved forward in water damage restoration, or have we lost sight of the fundamentals? I share my thoughts on why early make-safe action, smarter monitoring and better processes matter - because behind every claim is a person, a home and a life affected. People Matter. Outcomes Matter. Read my latest article below.

Why early make-safe action, immediate stabilisation and smarter monitoring matter.

Mould!

They’re everywhere, aren’t they? 🤔

Well… today I was cleaning my water bottle and discovered something that made me go 😱

MOULD… inside the drinking straw!

I generally keep my bottle pretty clean. I use a soft brush, wash it regularly and replace parts when needed.

But… life happened. One thing led to another, and this little bottle had been neglected for longer than I realised. 🤦‍♀️

And, of course, being an inspector in this space, my first thought was:

“Well, I guess I have to write about this!” 😂

We often think about mould in buildings — walls, carpets, ceilings, HVAC systems and damp areas.

But moisture + time + organic material = an opportunity for microbial growth, and that can happen in the everyday things we put in our mouths or breathe through.

There is good evidence that exposure to mould can contribute to respiratory symptoms, particularly for people who are allergic, have asthma or have other respiratory vulnerabilities. (CDC)

And the same principle applies to equipment that delivers air.

For example, research has demonstrated that microorganisms in contaminated CPAP humidifier water can make their way into the breathing circuit under experimental conditions. (PubMed)

But here is the important part: this doesn’t mean that every dirty bottle or CPAP hose will make you sick. The evidence isn’t that simple, and risk varies enormously between people and circumstances.

What it does remind us is that cleaning the things we drink from and breathe through matters.

So tonight:

🧽 Wash the bottle
🪥 Clean the straw properly
💨 Check those reusable hoses and breathing equipment
💧 Don’t leave moisture sitting around unnecessarily
🔍 And inspect those hard-to-reach areas!

Because sometimes the biggest problem isn’t the mould you can see…

It’s the mould you haven’t looked for.

And yes… I replaced my straw . 😂

🏅 Proud to Announce My Achievement as a Certified Indoor Air Quality (IAQ) Consultant

I am proud to announce that I have successfully achieved certification as an Indoor Air Quality (IAQ) Consultant through the Building Restoration Inspection Institute (BRII).

This certification recognises advanced knowledge in the assessment of indoor environments, combining building science with practical investigation techniques to identify and solve complex indoor environmental issues.

As an IAQ Consultant, my focus includes:

🌬️ Indoor Air Quality Assessments
🏠 Healthy Building Performance
💧 Moisture & Condensation Investigations
🦠 Mould & Microbial Contamination
❄️ Ventilation & HVAC Performance
🌡️ Temperature & Humidity Analysis
📷 Thermal Imaging & Building Diagnostics
📊 Evidence-Based Building Investigations

Indoor air quality is one of the most important factors affecting the health, comfort and performance of the spaces where we live, work and learn. Understanding how moisture, ventilation, building design and occupant behaviour interact is essential to creating healthier and more resilient buildings.

This achievement reflects my ongoing commitment to professional development and to providing clients with science-based advice that delivers practical, measurable outcomes.

A sincere thank you to everyone who has supported me throughout my journey. I look forward to continuing to advance healthy buildings and building science across Australia.

“Healthy buildings don’t happen by chance—they are designed, measured and verified.”

Condensation Explained: The Simple Guide Every Homeowner, Builder and Designer Should Know:

Condensation is one of the most misunderstood issues in buildings. Many people think it only happens on windows during winter, but in reality it can occur inside walls, ceilings, floors and roof spaces long before any visible damage appears.

The problem isn't simply "too much moisture." Condensation occurs when temperature, humidity and airflow combine under the wrong conditions.

What is Condensation?

Condensation occurs when warm, moisture-laden air comes into contact with a surface that is colder than the air's dew point temperature.

The excess water vapour changes from a gas into liquid water.

Think of a cold drink on a hot day. Water appears on the outside of the glass—not because it's leaking, but because moisture from the air condenses on the cold surface.

Buildings behave exactly the same way.

The Four Things Needed for Condensation

Every condensation problem involves four factors:

Moisture (humidity)
A cold surface
Air movement carrying moisture to that surface
Enough time

Remove just one of these and condensation usually disappears.

Warning Signs

Watch for:

Water droplets on windows
Black mould around windows
Musty odours
Bubbling paint
Peeling wallpaper
Damp wardrobes
Rust on screws or metal
Swollen skirting boards
Timber cupping
Ceiling stains

These are often symptoms—not the cause.

Two Reports. Two Different Outcomes. One Important Lesson.

I review a large number of technical reports every year, and I am still surprised by how often bias can influence the outcome.

Recently, I reviewed two plumbing reports relating to the same issue.

The first report, prepared for an insurer, stated it was unbiased. However, the conclusion relied on assumptions that favoured the insurer’s position. No testing was undertaken to support those assumptions. A professional opinion without supporting evidence may be considered an opinion, but it is not a conclusive finding.

The second report, commissioned by the strata manager, was very different. Testing was performed, the evidence was documented, and the conclusions were directly supported by the results. The outcome was evidence-based and defensible.

This highlights one of the biggest mistakes any inspector, assessor, consultant, or expert can make: allowing assumptions to drive conclusions rather than allowing evidence to guide them.

What concerns me most is the impact this has on clients. Recently, while discussing a claim, a highly educated professional—someone respected by their peers and accomplished in their field—told me they felt “stupid” dealing with the insurance process.

I hear this more often than I should.

The reality is that many intelligent and capable people become overwhelmed when navigating complex claims and conflicting expert opinions. It is not because they lack knowledge; it is because the system can be difficult to understand and challenging to challenge.

Good reporting should not advocate for a party. It should advocate for the facts.

Evidence first. Assumptions last.

Building the future of moisture investigation and healthy buildings in Australia.

Big milestone for us today.

After 12 years of industry involvement, research, and collaboration, we are excited to launch the new BEWG webpage and community platform.

The site is designed to showcase the groups, discussions, and future direction around:✔ Moisture detection✔ Mould and IAQ investigations✔ Building health✔ Sustainable drying systems✔ Education and industry collaboration

We believe the industry needs stronger connection, better education, and practical systems that support healthier buildings across Australia.

More updates, case studies, resources, and group discussions coming soon.

Check out the new webpage - https://www.bewg.au/

Thank you to everyone who has supported the journey so far.

This book is designed to provide information for homeowners, homebuilders, and other construction partners regarding the Mold-Free ProcessTM, a process by which the problems of mold and mildew may be controlled and, in some cases, eliminated by decisions made during the building process.

About Us

We specialise in moisture, mould, and indoor air quality — the hidden factors that impact building performance and human health.

Our work began in the field, solving real problems where buildings were failing and the cause wasn’t clear. What we found is simple:
when moisture is misunderstood, buildings deteriorate.

Through Moisture Detective®, we identify issues using evidence, not assumptions.
Through Building Environmental Wellness Group (BEWG), we connect moisture, air quality, and building science to provide real solutions.
Through BRII, we train industry professionals to better understand buildings and prevent failure.

We don’t just report problems — we find the cause and help fix it properly.
