Commercial Vent Hood Cleaning

Vent hood cleaning for kitchens that need the canopy, plenum, and vent path cleaned.

Vent hood is another common name for the canopy over commercial cooking equipment. Whatever the name, the cleaning needs are the same: grease collects on the canopy walls, behind the filters, and up into the vent, and that grease has to be removed down to bare metal where possible.

We clean vent hoods as part of a complete exhaust service so the vent path above the hood is not ignored. Every visit ends with filters reinstalled and the cooking area ready to use.

What this service covers

  • Vent hood canopy
  • Plenum and vent collar
  • Filters
  • Connected vent duct
  • Exhaust fan

Common problems we address

  • Discolored, sticky canopy
  • Grease in light fixtures
  • Smoke escaping the hood edges

Safety and NFPA 96

For commercial vent hood cleaning, NFPA 96 (the National Fire Protection Association standard for commercial cooking operations) is the usual reference for inspection, cleaning access, and documentation. The edition in force and how it is enforced depend on your local authority having jurisdiction. We clean thoroughly and document our work, but no contractor can guarantee an inspection result. Learn more about NFPA 96.

Benefits for your business

  • Cleaner, brighter cooking area
  • Better smoke capture
  • Lower fire risk
