Commercial decontamination services (including mould and allergens)
Commercial buildings face unique challenges when it comes to mould, moisture intrusion, odour, dust, and airborne contaminants. Left untreated, these issues can affect indoor air quality, disrupt operations, damage assets, and impact staff wellbeing.
Care Services brings more than 40 years of commercial decontamination experience, backed by international training and specialist techniques, to restore safe, clean, and healthy working environments. Our services are tailored to the needs of offices, government buildings, education providers, industrial premises, retail sites, hospitality venues, healthcare facilities, and multi-level commercial properties. Contact Care Services for an assessment and the right remediation strategy for your building.
Moisture, leak and building envelope expertise
Water and moisture damage is one of the leading causes of mould growth and indoor contamination in commercial spaces. Care Services has decades of experience drying offices, retail buildings, factories, warehouses, and multi-level commercial premises affected by leaks, appliance failures, roof ingress, and flooding. We were early participants in New Zealand’s leaky-building era of the late 1990s and undertook specialist training in the USA to ensure our remediation methods aligned with emerging international standards.
Every situation is fully assessed on a case-by-case basis, allowing us to determine the extent of moisture intrusion, identify hidden risks, and recommend the safest and most effective remediation plan.
Commercial mould, allergen and air quality remediation - Advanced techniques for safe and effective removal
Care Services provides comprehensive remediation for all types of mould and airborne contaminants found in commercial buildings. This includes surface mould, black mould, hidden mould within walls or ceilings, HVAC-related contamination, and airborne microbial growth. We treat the full spectrum of workplace allergens and particulates — such as dust, pollen, fine debris, and construction-related dust — all of which can affect staff health, indoor air quality, and overall building performance.
Our remediation process typically includes:
- Detailed inspection and optional air-quality testing
- HEPA vacuuming and filtration
- Antimicrobial and anti-fungal treatments
- Isolation and containment of affected areas
- Negative-air machines and HEPA air scrubbing
- Removal and safe disposal of contaminated materials (gib, insulation, underlay, etc.)
- Surface sealing or encapsulation where appropriate
For many commercial environments, a combination of professional cleaning and air scrubbing provides immediate improvement without introducing unnecessary chemicals — a valuable approach for offices, hospitality venues, schools, childcare centres, healthcare facilities, government buildings, and public-facing spaces.
We also provide practical advice on moisture, ventilation, building leaks, and environmental factors that contribute to mould and allergen recurrence, helping businesses maintain healthier indoor spaces long-term.
Internationally Trained Specialists - Our team has completed advanced remediation training in the USA, including work alongside one of New York’s leading restoration firms. Experience gained through large-scale emergency contamination projects — including work linked to the aftermath of 9/11 — provides us with a unique understanding of complex commercial remediation scenarios. We maintain global connections with experts responsible for developing major post-disaster restoration protocols, ensuring our approach remains aligned with the highest industry standards.
Contamination and public hazard management
Odour Remediation - We have extensive experience assessing and resolving odour contamination in large commercial buildings. In one major Wellington case, we collaborated with a leading US expert to develop a remediation protocol and returned the building to service quickly, helping minimise insurance exposure and operational downtime.
Dust & Airborne Particulate Contamination - Dust contamination can occur during construction, drilling, HVAC malfunction, or IT-room disturbances. Care Services has established pressurised clean-room environments with HEPA air scrubbing to allow safe dismantling, cleaning, and reassembly of sensitive equipment — including mainframe systems and electronic infrastructure. This capability is essential for data centres, laboratories, universities, specialist manufacturing, and corporate/government IT facilities.
Safety, documentation and compliance
Safe Practices for Sensitive Commercial Environments - Some remediation treatments require temporarily isolating areas or restricting access for safety. We manage containment and advise businesses clearly on when zones can be safely reoccupied — an essential part of working in hospitals, food-prep areas, aged-care environments, and childcare or educational facilities.
Reporting for Insurance & Compliance - If required, we can provide written remediation reports and photographs to support insurance claims, compliance requirements, or property transactions.
Work to Best Practice Standards - Although New Zealand does not have a formal standard for mould remediation, we follow international best practice to ensure every job is completed to a professional, transparent, and defensible standard.
