Ventilation Cleaning

Ventilation and ductwork systems are found in many buildings we frequent – museums, hospitals, offices, kitchens and many other premises. These systems are usually tucked away out of sight and gather contaminants.

Ventilation and ductwork systems are found in many buildings we frequent – museums, hospitals, offices, kitchens and many other premises. These systems are usually tucked away out of sight and gather contaminants. If not cleaned and removed these contaminants can provide a breeding ground for pests and bacteria.


It is essential to provide access to the system to ensure cleanliness of the ventilation systems is maintained. Even though current ductwork specifications, DW 144, call for access doors at pre-determined locations and distances there is a high chance of additional doors being required to clean the ductwork to H.V.C.A. TR19, HTM03-1 & C.I.B.S.E. TM26 standards. 


At JC Watson we are proud to be using advanced tools for ventilation cleaning such as the modern rotary brush technology and air movers to clean ventilation systems, which mitigates the need for confined space working. The vacuum removal system includes a three-stage filtration system to avoid the collected dust being re-circulated into the working area. In some hospital situations such as operating theatres, clinical hygiene standards need to be met. Therefore, the internal surfaces of the ductwork should be sterilized permitting microbiological checks to be conducted to establish the precise level of cleanliness.


Our vast experience in the industry allows our ventilation cleaning experts to provide quotations from supplied drawings, giving accurate take off measurements, alternatively we can provide a free site survey. Our operatives are also trained to the current BESA standards to ensure the highest level of service to our clients.
