When storms hit, we bring clarity, control, and clean air back to your home.

Following a recent severe storm system across Sydney's Northern Beaches, one homeowner discovered escalating moisture intrusion and early signs of mould within wall cavities and flooring. AAA Mould Removal was engaged immediately to perform a full remediation in accordance with IICRC S500 and S520 standards.

Within 7 days, we completed the project, restoring the property to a clean, dry, and safe condition with no compromise on safety, documentation, or compliance.

🧰 Project Summary

• Location: Northern Beaches, Sydney

• Cause: Storm-related water intrusion

• Duration: 7 days

• Total Cost: $7,500

Services Provided:

• Site moisture mapping & damage assessment

• Source removal of all water-damaged materials and disposal

• IICRC-compliant containment & decontamination zones

• HEPA air scrubbing with engineered negative air pressure

• Double-bagged and goose-necked contaminated material disposal

• PPE-protected crew under certified supervision

• Full documentation in Clean Claims (insurance-ready)

• Supply and setup all hardware

• Final cleanup and decommisioning of containment

• Consultantion with buiders for the post remediation buiding remedia work

• Liase with third party for PRV

1. Initial Assessment & Containment Setup

Our IICRC-certified team quickly responded to assess the property using professional moisture mapping tools. Stormwater had penetrated multiple internal wall assemblies and underfloor areas.

To contain the affected zone and prevent cross-contamination, we established:

• Full containment barriers with zipper entry access

• A dedicated decontamination chamber

• HEPA-filtered air scrubbers engineered to negative air pressure

2. Source Removal & Remediation Process

Following the IICRC S500 & S520 protocols, all porous water-damaged materials (gyprock, insulation, underlay) were removed via source removal — no fogging was used. We exposed structural framing for inspection and drying.

Contaminated debris was:

• Double-bagged and goose-necked to meet safe handling standards

• Transported off-site for compliant disposal

Throughout the process, all technicians wore full PPE, including disposable suits, P2 respirators, gloves, and eye protection.

3. Structural Drying & Project Documentation

Once the source materials were removed, structural drying commenced using axial air movers and a combination of LGR and desiccant dehumidifiers.

All environmental readings (RH, temperature, and GPP) were monitored 24/7 through our remote telemetry logging system, and drying goals were confirmed before demobilisation.

All remediation actions were thoroughly documented using Clean Claims, ensuring compliance with insurance carrier requirements and providing peace of mind to the homeowner.

🏠 Final Outcome

• Mould contamination was completely removed

• Structural elements were dried to IICRC target levels

• The area was cleared for safe reoccupation

• Detailed reports, readings, and photos were provided for insurance submission

❓ Frequently Asked Questions

Q: Why don’t you use fogging for mould?

A: We follow IICRC S520 standards, which prioritise source removal over fogging. Fogging can mask contamination but doesn’t remove it. We eliminate mould at its origin.

Q: What’s the purpose of containment and negative air?

A: Containment prevents mould spores from spreading to clean areas. Negative air ensures all airborne particles are pulled into HEPA scrubbers, not into your home.

Q: Do you provide insurance reports?

A: Yes. All work is logged in Clean Claims, including moisture data, photographic evidence, and technician notes. This supports your insurance claim and serves as a long-term record.
