Hamilton's Local Mould Assessment Specialists
Scaada NZ provides professional mould inspection and testing services to Hamilton homeowners, landlords, tenants, property managers and building professionals. Whether you've discovered visible mould growth or suspect hidden contamination, our McCrone-certified mycologists and MAIOH-accredited occupational hygienists can identify exactly what you're dealing with and advise on appropriate remediation.
What is a Mould Assessment?
A professional mould assessment goes beyond simple testing. Our qualified assessors evaluate your property systematically to identify mould contamination, determine its source, and provide evidence-based recommendations for remediation.
What a Comprehensive Mould Inspection Involves
- Visual inspection - Identifying visible mould growth, moisture sources, and water damage patterns throughout your property
- Surface sampling - Tape lifts and biotapes collected from suspect areas, analysed using ASTM D7658-17 methodology
- Airborne spore sampling - Spore trap samples to assess indoor air quality, as compared with relevant industry guidelines
- Moisture content readings - Non-invasive moisture measurements of building materials to identify hidden dampness
- Temperature and relative humidity - Environmental conditions that influence mould growth potential
- Site documentation - Photographs and detailed notes supporting the laboratory findings
When to Choose Professional Assessment vs. DIY Testing
DIY sample kits are suitable when you have a small area of visible mould and simply want to identify what species is present. We provide sample kits with instructions for straightforward cases.
Professional on-site assessment is recommended when:
- You or family members are experiencing health symptoms that may be mould-related
- You need documentation for insurance claims or legal matters
- You're buying or selling a property with suspected mould issues
- You suspect hidden mould behind walls, under floors, or in ceiling cavities
- Previous remediation has failed or mould keeps returning
- The affected area is larger than 1 square metre

Understanding Your Mould Assessment Results
Our laboratory reports provide detailed analysis using internationally recognised standards. Here's how we interpret and communicate findings:
IICRC S520 Condition Ratings
We classify mould conditions according to ANSI/IICRC S520 Professional Mould Remediation standards:
- Condition 1 - Normal Fungal Ecology: Mould spores present at levels typical of outdoor air. No remediation required.
- Condition 2 - Settled Spores: Elevated spore levels from contamination originating elsewhere. Surfaces may need cleaning but no active growth present.
- Condition 3 - Active Growth: Visible mould growth or confirmed active colonisation. Professional remediation recommended.
Airborne Spore Interpretation
For air samples, we reference BRANZ SR452 guidelines for New Zealand residential buildings, alongside recognised international guidelines for indoor mould spore concentrations:
- Naturally ventilated NZ homes typically show indoor spore counts below 1000 fungal structures per cubic metre (fs/m³)
- Indoor counts are compared against outdoor reference samples taken at the same time
- Elevated indoor counts or different species composition may indicate an indoor mould source
Surface Sample Interpretation
- Normal ecology: 50-500 spores/cm² of common environmental species
- Elevated levels: Counts above 1000 spores/cm² suggest contamination requiring attention
- Species significance: Finding water-damage indicators like Stachybotrys or Chaetomium points to ongoing moisture problems, while Aspergillus and Cladosporium often indicate humidity or ventilation issues
What This Means for Your Property
- What mould you have - We identify specific genera and species, distinguishing common environmental moulds from more concerning types
- Source identification - The types and distribution of mould help pinpoint moisture sources and building issues
- Health context - Different moulds pose different risks, particularly for allergic or immunocompromised individuals
- Remediation scope - IICRC condition ratings translate directly into appropriate remediation approaches, ensuring you're neither under-treating nor over-treating the problem

Post-Remediation Verification (PRV)
After mould remediation work is completed, independent verification confirms the job has been done properly. Post-Remediation Verification (PRV) provides documented evidence that contaminated areas have been successfully restored to normal fungal ecology.
When PRV is Recommended
- After professional mould remediation to confirm successful completion
- When occupants include immunocompromised individuals, infants, or elderly persons
- For insurance claim documentation and sign-off
- Before re-occupancy of properties with significant contamination history
- When landlords need evidence of compliance for tenants
What PRV Involves
- Visual inspection - Confirming all visible mould has been removed and affected materials properly disposed
- Surface sampling - Testing remediated surfaces to verify Condition 1 (normal fungal ecology) has been achieved
- Air sampling - Comparing indoor air quality against outdoor reference to confirm no elevated spore levels
- Documentation - Detailed clearance report suitable for insurance, tenants, or property records
PRV assessment follows ANSI/IICRC S520 clearance criteria, providing objective third-party verification that remediation has met professional standards.
Enquire About PRVHealthy Homes & Compliance Documentation
Under the Residential Tenancies (Healthy Homes Standards) Regulations 2019, landlords must ensure rental properties meet minimum standards for heating, insulation, ventilation, moisture and drainage, and draught stopping. While the regulations don't specify mould testing requirements, mould growth is often a symptom of underlying moisture and ventilation issues.
How Mould Assessment Supports Compliance
- Identify root causes - Our assessments identify moisture sources and ventilation deficiencies contributing to mould growth
- Document property condition - Laboratory reports provide objective evidence of indoor environmental quality
- Guide remediation priorities - Results help you address the most significant issues first
- Verify improvements - Post-remediation testing confirms that interventions have been effective
For Property Managers & Landlords
Professional mould assessment demonstrates due diligence in maintaining healthy rental properties. Our reports provide clear documentation that can support discussions with tenants, insurance providers, and maintenance contractors about property condition and remediation needs.

- Advanced Assessment: Comprehensive assessment with all rooms evaluated using spore traps and biotapes for trace mould spores and growth. Includes reporting on other potential allergens if found, plus detailed review of all mould spores with remedial recommendations.
Contact us to discuss which option suits your situation.
What's the difference between mould testing and mould inspection?
Mould testing refers to laboratory analysis of samples - we examine tape lifts, biotapes, or air samples under the microscope to identify what mould species are present and in what quantities.
Mould inspection (or assessment) is a professional site evaluation that includes visual inspection, moisture readings, strategic sample collection, and interpretation of findings in context. An inspection determines not just what mould is present, but why it's there and what should be done about it.
You can send us samples for testing without a full inspection, or we can provide a comprehensive on-site assessment that includes laboratory analysis.
How long does a mould assessment take?
On-site inspection typically takes 1-2 hours depending on property size and complexity. Laboratory analysis follows, with standard results available within 3-5 business days. Priority and same-day options are available for urgent cases.
Can I do mould testing myself or do I need a professional?
DIY sample kits are suitable when you have a small area of visible mould and simply want to identify the species. We provide tape lift kits with instructions for straightforward cases.
Professional assessment is recommended when:
- You or family members have health symptoms that may be mould-related
- You need documentation for insurance claims or legal matters
- You're buying or selling a property
- You suspect hidden mould (behind walls, under floors)
- The affected area is larger than 1 square metre
- Previous remediation has failed
What qualifications should a mould inspector have?
Look for assessors with recognised training in mould analysis and occupational hygiene. Key credentials include:
- McCrone Research Institute certification - The international standard for mould microscopy training
- AIOH membership - Australian Institute of Occupational Hygienists accreditation demonstrates expertise in indoor environmental quality
- Knowledge of IICRC S520 - The professional standard for mould remediation ensures assessors understand industry protocols
Our team holds these qualifications. See our About page for full credentials.
