Building a new home? Don’t let hidden moisture ruin your investment.

At Confluence Environmental, we provide expert mould and moisture assessments during construction for homes across Newcastle, Lake Macquarie, and the Hunter Valley.

Whether you’re an owner-builder, developer, or residential construction company, our consultants deliver early-stage moisture detection to help you stay compliant, prevent defects, and ensure a safe, dry handover.

Why Moisture Checks Are Essential During Construction

Moisture damage and mould can form before a home is even complete — especially in regions like Lake Macquarie and the Hunter with frequent rainfall, high humidity, and clay-based soils.

Without a proactive inspection:

• Wet wall frames can trap moisture behind cladding

• Subfloor moisture can compromise flooring

• Roofing and plumbing penetrations may leak

• Mould may begin forming in ceilings or insulation

• Minor defects can become major warranty disputes

We help catch problems early — so you can fix them fast.

Our New Build Moisture Inspection Services

• Framing stage moisture testing before wrap/cladding

• Lock-up stage inspections post-roof installation

• Pre-handover mould and moisture checks

• Moisture meter testing and thermal imaging

• Visible mould and water damage documentation

• Optional air sampling or surface mould testing

• Photo-backed reports with clear recommendations

Local Moisture Risks in the Region

Newcastle & Lake Macquarie:

• Coastal exposure (e.g., Swansea, Belmont, Merewether)

• Stormwater runoff issues in sloped blocks

• Sea mist and saltwater ingress during weather events

Hunter Valley:

• Condensation risks in winter (e.g., Singleton, Maitland)

• High humidity zones near rivers and floodplains

• Trapped moisture in slabs from expansive soils

Local builders know the risks — but a third-party assessment ensures nothing is missed before handover.

Mould Testing & Analysis (Optional)

Where mould is detected or suspected, we can also provide:

• Airborne spore sampling

• Surface swab or tape-lift testing

• Post-remediation verification testing
  All analysis is completed through NATA-accredited labs, giving you evidence you can rely on.

Who Needs a New Build Mould Inspection?
