Reactive Investigation of Specific Issues
When an indoor air quality problem arises — an odour complaint, staff feeling unwell, visible mould, or a regulatory notice — you need a rapid, targeted investigation. We identify the root cause and provide actionable corrective recommendations, typically within 48 hours of instruction.
Common Investigation Triggers
- Staff complaints about odours, headaches, or respiratory irritation
- Visible mould or damp in workspaces
- Sick Building Syndrome (SBS) concerns
- Post-refurbishment air quality queries
- Environmental Health enforcement notices
- Insurance or liability-driven assessments
Our Investigation Process
We deploy targeted monitoring and diagnostic assessment to identify the source of the problem. This includes real-time air quality measurement, surface and air sampling where required, ventilation system review, and building fabric inspection. Results are interpreted against established standards and presented with prioritised recommendations.
Response Times
Standard reactive investigations are arranged within 48 hours. Contract clients benefit from priority response and dedicated account management. For urgent situations involving regulatory compliance or health risk, we offer expedited deployment.
