Complete Exhaust Hood and Kitchen Exhaust System Cleaning
Kitchen Guard is a compliance-driven exhaust hood cleaning company built around fire prevention. We are not a janitorial cleaning vendor.
A hood that looks clean on the surface does not mean the system is safe. Grease accumulation inside ductwork, plenums, and exhaust fans is where most fire risk and compliance failures begin. A properly cleaned kitchen exhaust system requires access, containment, and trained execution across the full air path.
Kitchen Guard cleans the entire exhaust system from the hood canopy through the ductwork and up to the rooftop exhaust fan using certified technicians and documented processes.

What is Exhaust Hood Cleaning?
Exhaust hood cleaning is the professional cleaning and maintenance of a commercial kitchen ventilation and(delete) exhaust system to reduce grease buildup throughout your commercial kitchen space and support compliance with fire safety requirements with the NFPA (National Fire Protection Association) and local Fire Codes.
Complete exhaust hood cleaning includes (but is not limited to):
- The underside of the hood and canopy
- Hood filters
- The plenum (the open space leading into ductwork)
- Exhaust ductwork
- Exhaust fans (including rooftop fans)
Kitchen Guard ensures your entire system is cleaned thoroughly — not just the visible areas. It’s our core competency performed by highly trained and certified technicians.
Code-Compliant Cleaning & Inspection Readiness
Exhaust hood cleaning isn’t just about appearance — it’s about safety and compliance. The NFPA estimates U.S. fire departments respond to about ~7,000 restaurant and bar fires per year. Kitchen Guard is here to protect your commercial kitchen and keep your staff and customers safe.
Commercial kitchen exhaust systems are typically governed by fire safety standards and local inspection requirements, and cleaning frequency is often based on cooking volume and grease production. Under NFPA 96 guidelines, exhaust hoods should be inspected anywhere from once a month to once a year, depending on how heavily the kitchen is used.
Kitchen Guard follows recognized best practices (including industry standards like NFPA 96) and provides photo documentation after every service to help support inspections and insurance compliance.

Reduce Fire Risk. Protect Your Business. Maintain Clean Airflow.
Failure to keep up with your commercial kitchen exhaust hood cleaning increases risk in several ways:
- Fire Risk: Grease is flammable — and buildup increases the chance of a grease fire
- Inspection & Compliance Risk: Missed cleanings can lead to failed inspections, fines, or closures
- Insurance Risk: Lack of documentation or compliance can create problems during audits or claims
- Equipment Wear: Dirty systems restrict airflow and cause fans and equipment to work harder and fail prematurely, increasing operating costs
- Air Quality & Health: Grease buildup affects indoor air quality and can impact staff health and food safety
A consistent commercial kitchen exhaust cleaning schedule helps reduce risk and supports smoother operations.
