Commercial Exhaust Hood Cleaning

Type I grease exhaust hood cleaning over fryers, ranges, and grills.

Grease exhaust hoods, often called Type I hoods, are installed over appliances that produce grease-laden vapor. Their design depends on the filters, the plenum, and a sealed duct to safely carry grease out of the building. Each of those parts needs regular cleaning.

Our exhaust hood cleaning covers each hood in the kitchen, including back-of-house hoods that are easy to forget, such as prep kitchen fryers and bakery ovens connected to grease exhaust.

What this service covers

  • Type I grease hoods
  • Plenum and filters
  • Hood lights and lens exteriors
  • Connected duct and fan

Common problems we address

  • Secondary hoods missed on previous cleanings
  • Grease around hood light fixtures
  • Uneven buildup across hood sections

Safety and NFPA 96

For commercial exhaust 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

  • Every hood cleaned to a consistent standard
  • Documentation by hood
  • Cleaner work environment
