How grease travelsGrease-laden vapor rises from the cooking line into the hood, up the duct, and out the rooftop fan. Grease collects at every stage. Part of the hood is drawn cut away to show the filters.

Grease doesn’t stay in the filters

Grease from your cooking line collects inside the hood, the duct, and the rooftop fan. Over time, that buildup becomes fuel.

NFPA 96 is the national fire code standard for commercial kitchen exhaust systems. It sets how often your system must be checked for grease, and it requires cleaning when grease is found.1

Who we work with

  • Restaurants, bars, and food trucks with hoods.
  • Church and school kitchens.

How we do it

  1. Walk through

    We look at your hood, duct, and fan, and give you a firm quote.

  2. Protect

    We cover the cooking line and floors, and protect the fire suppression nozzles.

  3. Clean

    Hood, filters, ductwork, and rooftop fan, degreased and washed down to bare metal.

  4. Capture

    Wash water and grease are collected and disposed of properly. None of it goes down a storm drain.

  5. Document

    A dated sticker on your hood, and a written report with photos.

What you get after every cleaning

This is the paperwork fire marshals look for. The City of Bryan Fire Marshal’s Office, for example, expects a service tag with the cleaning date and the next service date, plus a written report with photos.2

  • A dated service sticker on your hood, showing your next service date.
  • A written report with before-and-after photos.
  • Notes on anything we couldn’t reach or anything that needs repair, like a missing access panel.
  • Hood, filters, ductwork, and rooftop fan, cleaned down to bare metal.

Your fire suppression system, protected. We cover the nozzles before we start and leave the system exactly as we found it.

Questions about hood cleaning

How often do we need cleaning?

It depends on your cooking. NFPA 96 sets the check schedule, from monthly for wood or charcoal cooking to once a year for low-volume kitchens like churches.1 We’ll match your schedule to your kitchen.

Do you work at night?

Yes. We schedule around your hours, so the kitchen is ready when your crew arrives.

Do you clean the rooftop fan?

Yes. The fan, its housing, and the grease containment around it. If your fan doesn’t have a hinge kit for safe access, we’ll tell you.

What happens to our fire suppression system?

We cover and protect the nozzles before we start, and we leave the system exactly as we found it.

Can you set up a recurring schedule?

Yes. We’ll put you on a schedule that fits your kitchen and call ahead before each service.
