How often should our exhaust system be cleaned?

Frequency follows cooking volume and fuel type — high-volume frying can need quarterly attention. The free survey grades accumulation and recommends an interval aligned to NFPA 96 guidance.

Can you standardise cleaning across many outlets?

Yes — multi-outlet programmes run on a rolling calendar with identical scope, evidence format and central reporting for the estate.

Will cleaning disrupt trading?

Work is executed in night or off-service windows, and kitchens are handed back service-ready each morning.

Industry

Restaurants, QSR & Commercial Kitchens.

High-volume cooking writes grease into every metre of the exhaust path — hood, plenum, duct and fan.

DCC cleans the full path to bare metal, installs access panels where the network cannot otherwise be reached, and runs drain and grease-trap programmes so the back of house keeps pace with the front.

01Grease load is a fire-safety control issue

Accumulation inside concealed ductwork is fuel running through the building. Frequency must follow cooking volume, not a calendar habit.

02Concealed runs get skipped

Hood-only cleaning leaves the duct network untouched. Access panels make the full path cleanable — permanently.

03Traps and drains fail at peak service

Loaded grease traps and slow lines surface as odour and backups during trading. Load-based cleaning calendars prevent emergency call-outs.
