Grease Duct Cleaning

Grease duct cleaning addresses the interior ductwork that connects commercial kitchen exhaust hoods to rooftop fans. These enclosed ducts accumulate highly flammable grease deposits that represent one of the most dangerous fire risks in any commercial kitchen. NFPA 96 (the National Fire Protection Association standard governing commercial kitchen exhaust systems) mandates that ductwork be cleaned on the same schedule as hoods, with frequency determined by cooking volume and type. Proper duct cleaning requires access panels installed at regular intervals along the ductwork, including at every change of direction. Without adequate access points, technicians cannot reach all interior surfaces, leaving hidden grease deposits that create fire risk and result in non-compliance during fire marshal inspections. Many kitchen fires originate in grease-laden ductwork, making this service critical for safety and insurance compliance.
