Odour Investigation
Trusted since 1999 · Proven delivery partner
Odour complaints in commercial buildings are disruptive, difficult to diagnose, and damaging to occupant satisfaction. Green Air Monitoring delivers systematic odour investigations that identify the source, pathway, and cause — providing the evidence and recommendations needed for effective resolution.
Common Odour Sources
Building odours can originate from a wide range of sources, many hidden within the building fabric or services.
- Drainage faults — sewer gas ingress through dry traps or failed seals
- HVAC contamination — microbial growth in ductwork, AHU coils, or condensate trays
- Building fabric — damp, mould, or off-gassing from materials
- External sources — traffic, construction, industrial activity, or neighbouring premises
- Internal activities — cooking, cleaning products, or process emissions
Investigation Methodology
Our odour investigation follows a structured diagnostic process: occupant interviews and complaint pattern analysis, systematic walkthrough and source mapping, targeted air sampling (VOCs, microbial, specific gases), HVAC system inspection, and building fabric assessment. Results are interpreted to identify the specific source and pathway.
Resolution Support
We don't just identify the problem — we provide prioritised remediation recommendations and can verify that corrective actions have been effective through follow-up monitoring.
