Why This Matters
Mould growth in commercial buildings is typically caused by moisture, condensation, inadequate ventilation, or thermal bridging. Beyond health risks (respiratory sensitisation, allergic reactions), visible mould damages building reputation and can trigger formal complaints from tenants and occupants. Under the Landlord and Tenant Act 1985 and the Homes (Fitness for Human Habitation) Act, landlords have a legal obligation to maintain properties free from serious damp and mould hazards.
- Mould spores can trigger respiratory and allergic reactions in building occupants
- Persistent damp indicates underlying building fabric defects requiring investigation
- Remediation without root cause analysis leads to costly recurrence
- Post-remediation verification is essential for compliance and tenant confidence
- Landlords face legal liability under the Homes (Fitness for Human Habitation) Act for unresolved mould
Our Approach
We conduct visual assessment, surface sampling (tape-lift and swab), and volumetric air sampling for culturable fungi using an Andersen impactor. Environmental measurements (humidity, temperature, dew point) identify moisture sources. Reports include species identification, concentration data, root cause analysis, and remediation guidance.
