Hood Cleaning,
Done Right

Restaurant hood cleaning exists because grease is flammable and exhaust hoods are built to collect it. Every ticket a kitchen fires sends grease-laden vapor up into the hood, where it cools and sticks to the canopy, the baffles, the duct walls, and eventually the rooftop fan. Left alone, that residue does not stay put — it thickens into a fuel source sitting directly above an open flame or a hot fryer line.

Egg Harbor Township runs a busier kitchen economy than its size might suggest. The Black Horse Pike and Tilton Road corridors are lined with chain restaurants, diners, and hotel food service, and the township's position next to Atlantic City International Airport and the Atlantic City casino corridor keeps commercial kitchens running long hours year-round rather than on a summer-only shore schedule. More covers per week means faster grease accumulation, which means the cleaning interval your kitchen actually needs is often shorter than operators assume.

NFPA 96 is the national standard that sets minimum cleaning frequency for kitchen exhaust systems, and it is enforced locally by Atlantic County fire officials under the same framework the NJ Division of Fire Safety applies statewide. Kitchens running solid-fuel cooking or wok stations are typically looking at monthly cleaning; moderate-volume operations — burgers, fryers, grilled items — usually land on a quarterly interval. None of this is optional paperwork. Insurance carriers and health inspectors routinely ask for signed documentation proving the work happened on schedule, not just that it happened at some point.

A dirty hood is also a cost problem most operators do not connect to their utility bill. When the baffle filters load up with grease, the exhaust fan has to pull harder to move the same volume of air. That shows up as a hotter kitchen, higher energy draw, and a system more likely to underperform during a Friday dinner rush. Servicing the hood, baffles, duct, and fan together keeps airflow at the level the system was designed for.

When One Visit Should Cover More Than the Hood

Most Egg Harbor Township kitchens get better value from a full system cleaning — hood, duct, and exhaust fan — in the same visit rather than scheduling each component separately. If your kitchen is also on a grease trap pump-out schedule, we can combine that work into the same after-hours appointment so your line only loses one night, not two.

Filter exchange runs on a shorter, separate cycle for kitchens that saturate their baffles faster than a full degreasing schedule can keep up with. We swap in a clean set of filters, take the dirty ones for cleaning off-site, and repeat the cycle — no appointment slot lost waiting on parts.

Warning Signs Your Exhaust System Needs Attention Now

Waiting for a fire marshal visit to prompt a cleaning is a gamble. A few signs mean the system needs service before an inspector ever shows up.

Grease dripping or pooling along the hood edges is the clearest signal — if it is visible on the outside of the canopy, the interior is worse. Smoke that hangs over the line longer than it used to, with no change in cooking volume, points to a fan or duct that has lost airflow to grease buildup. Up on the roof, a dark stain spreading out from the exhaust fan housing means the grease containment tray has already overflowed.

Inside the building, a sulfur smell rising from floor drains — worse on warm days or after a busy shift — usually means a grease trap at or past capacity. It will not resolve on its own, and it gets worse with heat and volume. A grease trap pump-out is the only real fix.

What a Professional Cleaning Crew Should Deliver

A real hood cleaning is not a rag and a spray bottle. It starts with a pre-clean inspection to gauge grease load and flag any mechanical issues, followed by drop covers over your equipment before a commercial-grade hot degreaser goes on. The crew lets it dwell, then scrubs and pressure-rinses from the canopy down through the duct to the rooftop fan. Every ounce of grease collected leaves the property — none of it goes down a drain or onto the roof membrane.

At the end of the visit you get a signed service report with technician name, date, areas cleaned, and any deficiencies noted. File it with your health permit and fire suppression records — that report is exactly what gets requested if Atlantic County fire officials ask for proof of a compliant cleaning schedule.

When Not to Call Us

If the underlying system was installed wrong — undersized duct, a fan that cannot handle the BTU load, makeup air that never balanced — no amount of cleaning fixes that. We will tell you exactly what we find during inspection, but correcting mechanical or installation problems is HVAC contractor work, not cleaning work.

We also do not service residential range hoods. Our crew and equipment are built for commercial kitchen volume. If you are running a home kitchen or a small café with a recirculating hood, we are not the right call — a residential appliance technician is.

Cleaning requirements are governed by NFPA 96 and enforced locally by the NJ Division of Fire Safety. For grease trap requirements, refer to the EPA's FOG prevention guidance.
