Soiled supply and extract ductwork undermines air quality and compliance. We survey, clean and certify general ventilation systems, AHUs and associated plant.
What we do
- Ventilation hygiene surveys — assessing the cleanliness of general ventilation ductwork against TR19®.
- AHU and ductwork cleaning — cleaning air handling units, supply and extract ductwork and associated systems.
- Post-clean verification — measured evidence that the system meets the required cleanliness standard.
- Compliance reporting — certificates and records for insurers and auditors.
Standards
Our ventilation and air handling work follows the BESA TR19® guide for ductwork hygiene.
