When mould contamination requires professional intervention, the process matters enormously. Professional mould remediation following IICRC S520 standards ensures safe, effective removal that prevents recurrence—while unprofessional approaches often make problems worse.
As IICRC-certified mould remediation specialists, we follow strict protocols developed through decades of industry research and experience. This guide explains what professional remediation actually involves and why certification matters.
What is the IICRC?
The Institute of Inspection, Cleaning and Restoration Certification (IICRC) is the global authority for restoration industries. Their S520 Standard provides the definitive protocol for professional mould remediation.
Why IICRC certification matters:
- Evidence-based protocols (not guesswork)
- Regular training and testing requirements
- Adherence to Australian building codes
- Insurance recognition
- Consumer protection through accountability
The IICRC S520 Standard Overview
The S520 Standard covers:
- Assessment methodologies
- Containment procedures
- Removal and disposal protocols
- Worker safety requirements
- Verification testing
- Documentation standards
Professional Remediation Process
Step 1: Pre-Remediation Assessment
Before work begins, IICRC technicians conduct detailed assessment as explained in our professional assessment guide.
Step 2: Containment Setup
Purpose: Prevent mould spores spreading to unaffected areas during removal.
Methods:
- Physical barriers: Heavy plastic sheeting seals work area
- Negative air pressure: HEPA-filtered air machines create lower pressure in work zone
- Air scrubbers: Filter airborne spores continuously
Step 3: PPE and Safety
Technicians wear appropriate protective equipment based on contamination level.
Step 4: Mould Removal
Porous materials (heavily affected):
- Removed and disposed of properly
- Includes drywall, insulation, carpet, padding
- Bagged in sealed containers
Non-porous or salvageable materials:
- Cleaned with specialized antimicrobial treatments
- HEPA vacuumed
- Verified clean
Step 5: Cleaning and Sanitization
- All surfaces HEPA vacuumed
- Appropriate cleaning agents applied
- Antimicrobial treatments where indicated
Step 6: Drying
- Industrial dehumidifiers
- Air movers for circulation
- Moisture monitoring until dry
Step 7: Verification
- Visual inspection
- Clearance testing (air sampling)
- Moisture verification
- Documentation
Why Professional Matters
Professionals provide:
- Proper containment (prevents spreading)
- Appropriate PPE (protects workers)
- Correct removal methods
- Proper disposal
- Verification of success
