DCUK FM, the country’s leading Ventilation Hygiene, Ductwork Cleaning and Asbestos Remediation specialists

DCUK FM, the Air Quality division of Marlowe Critical Services, are leading experts in the cleaning and decontamination of ventilation systems, ductwork cleaning, management, kitchen extract cleaning, asbestos removal and building refurbishment. We also created the world’s first ductwork deposit monitoring sensor, which provides real time information of the deposit build up within ductwork.

Since April 2006 it became an offence if systems are not maintained from a fire risk prospective (Section 17 of the RRO). We carry out communal ductwork cleaning for direct private and public customers and FM Service providers across the UK.
