Mould & Indoor Air Quality Assessments
Creating Healthier, Safer Indoor Environments
We understand how critical indoor air quality (IAQ) is to health, comfort, and productivity. With people spending over 80% of their time indoors, poor air quality can quickly lead to respiratory irritation, fatigue, reduced performance, and long-term health risks.
We provide professional mould testing and indoor air quality assessments across New Zealand, helping businesses and property owners identify hidden contaminants, assess risks, and implement effective control measures before they impact health or productivity.
Our team of Certified Occupational Hygienists and Indoor Air Quality Specialists use recognised sampling and analytical techniques to pinpoint contamination sources, confirm exposure levels, and recommend effective remediation strategies in line with the Health and Safety at Work Regulations 2016 and World Health Organization (WHO) indoor air quality guidance.
We assess a full range of physical, chemical, and biological parameters in offices, schools, industrial facilities, and residential buildings, delivering clear, practical recommendations for control and remediation.
Our Mould & Air Quality Services
Surface & Airborne Mould Sampling
We collect surface swabs and airborne spore samples using calibrated pumps and spore traps to identify mould type and concentration. Results are laboratory analysed and compared to indoor and outdoor reference levels.
Indoor Air Quality Testing
We assess temperature, humidity, CO₂, CO, VOCs, and particulate matter to determine whether ventilation performance or moisture issues are impacting occupant health and comfort.
Moisture & Source Tracing
We investigate root causes such as leaks, condensation, or ventilation failures and provide targeted remediation recommendations.
Post-Remediation Verification
We confirm the effectiveness of cleaning or remediation works through follow-up testing to ensure mould has been removed and indoor air quality restored.
Temperature & Relative Humidity
Assessment of thermal comfort conditions and moisture levels to prevent condensation and mould growth.
Gas Concentrations
Testing for CO₂, CO, NOₓ, and O₂ to evaluate ventilation performance and exposure risks.
Microbial Contamination (Mould & Bacteria)
Airborne and surface sampling to identify mould spores, bacteria, and other microorganisms with laboratory analysis.
Volatile Organic Compounds (VOCs) & Formaldehyde
Assessment of chemical off-gassing from materials, furniture, and cleaning agents.
Dust & Particulates (PM₁₀ & PM₂.₅)
Measurement of airborne particles affecting respiratory health and indoor cleanliness.
Ventilation Effectiveness
Evaluation of airflow and HVAC performance to identify poor circulation or inadequate air exchange.
Lighting Levels
Assessment of indoor lighting conditions supporting comfort, safety, and productivity.
Air Distribution Effectiveness
Evaluation of airflow patterns to ensure effective contaminant removal throughout indoor spaces.
