Mould in SEQ buildings

## A moisture problem, not just a surface problem

South East Queensland’s subtropical climate — temperatures typically above 20°C year-round and indoor humidity that regularly exceeds 70% without adequate ventilation — creates near-ideal conditions for mould growth.

Older timber-framed homes, common in suburbs such as Annerley, Greenslopes, Ashgrove and Taringa, are particularly susceptible, as are basements, subfloor cavities and poorly ventilated bathrooms and laundries in Gold Coast apartment buildings.

Mould is almost always symptomatic of a moisture problem — a roof leak, rising damp, condensation, flood inundation or poor ventilation. Treating the surface without addressing the moisture source guarantees recurrence, so our process always begins with identifying and eliminating the underlying cause.

Our process

## Our mould remediation process

1. #### Assessment & air quality testing

   Visual inspection and, where warranted, surface sampling and accredited laboratory air testing to establish the extent, species and appropriate remediation level (I–IV per IICRC S520).

2. #### Moisture source identification

   We trace and document the moisture pathway using moisture meters, thermal imaging and roof or subfloor inspection. The source must be eliminated before or during remediation.

3. #### Containment

   For significant contamination we establish physical barriers using polyethylene sheeting and HEPA-filtered negative air pressure, preventing cross-contamination to unaffected areas.

4. #### Safe work practices

   Technicians work in appropriate PPE — respirators, disposable suits and gloves — per Queensland WHS requirements and IICRC S520 protocols.

5. #### Mould removal

   Non-porous surfaces are cleaned with antimicrobial agents and HEPA vacuuming. Porous materials with significant penetration are removed under a controlled, documented strip-out protocol.

6. #### Antimicrobial treatment & encapsulation

   Affected areas receive antimicrobial treatment, and registered encapsulant coatings are applied to structural timber where appropriate.

7. #### Clearance testing

   We recommend a clearance air quality test by an accredited hygienist — documented assurance the remediation was effective, important for claims, sales and strata disputes.

8. #### Reinstatement & prevention

   Stripped areas are reinstated and, where appropriate, ventilation, vapour barriers or drainage improvements are installed to prevent recurrence.

Why it lasts

## Remediation that addresses the cause

A standard residential remediation — a single room with localised growth — typically takes 1–3 days. Extensive contamination involving structural strip-out and reinstatement can take 1–3 weeks.

Mould Remediation — FAQs

## Common questions

Mould exposure can cause respiratory irritation and allergic reactions, and certain species (including Stachybotrys, commonly called “black mould”) are associated with more severe impacts under prolonged exposure. We encourage occupants of heavily affected properties to seek medical advice. Our role is to remove the mould safely and address the moisture cause.

Surface mould on non-porous tiles and glass can sometimes be managed with proprietary cleaners. But mould in wall cavities, subfloors, insulation or structural timber requires professional remediation. DIY bleach on porous surfaces addresses appearance only — not deep mycelium growth — and does nothing about the moisture cause.

A standard residential project (single room, localised growth) typically takes 1–3 days. Extensive contamination across multiple areas, or involving structural strip-out and reinstatement, can take 1–3 weeks. We provide a clear programme at the scope stage.

Mould recurs if the moisture source is not eliminated. Our process specifically identifies and addresses the underlying moisture pathway, and we provide post-remediation recommendations for ventilation and maintenance to reduce recurrence risk.
