Trash chute questions, answered

It depends on the building. We recommend cleaning quarterly for hospitals, hotels and heavy-use buildings, twice a year for most apartment buildings, and at least once a year for everything else. NYC rules don’t set a frequency, but they do require chutes to be kept clean, sanitary and free of vermin and odors.

Because bags leak. Food, liquids and grease run down the walls of the chute and coat the intake doors and baffles, and that film rots, worst in warm months. Deodorizer only covers it. The fix is cutting the grease off the chute walls, doors and compactor area, then keeping a cleaning schedule.

They can. A chute and compactor that aren’t cleaned give pests food, moisture and a path through every floor of the building. Regular cleaning, bagged trash and a pest program cut pest pressure. In NYC, owners must treat chutes and refuse rooms as often as needed and keep records of the treatments.

Yes, while we’re working on it. Intake doors stay shut while the shaft is washed, so nobody drops trash on the crew or into wet chemicals. We schedule around your building and give you the timing in advance so the super can post a notice on every floor.

Keep out liquids, loose cat litter, unbagged food, bedding and cloth, hangers, blinds, pizza boxes, anything bigger than the hopper, recyclables and anything burning. Rechargeable batteries are illegal in NYC trash, chute included. Bag and tie everything else.

A baffle is the vinyl piece along the bottom of a chute’s intake door. It seals the gap so smoke, odor and debris stay inside the chute instead of drifting into the hallway. Grease and grime build up on it fast, and many cleaning crews skip it. We clean the baffles on every job.

Yes. In most buildings the “compactor chute” is the trash chute, and the compactor is the machine at the bottom that presses the trash into bags or containers. A proper cleaning covers the chute and the compactor area, because grease and spillage build up where the two meet.

An incinerator chute is a trash chute that once fed a building’s own incinerator. New York apartment buildings burned trash on site for decades; many still use the old masonry flue as their chute, now ending at a compactor. NYC’s chute rule expressly allows existing incinerator flues to be used as refuse chutes.

In stages. Larger apartment buildings built after May 20, 1968 had to have compactor systems instead, and most building incinerators were shut down in the early 1970s. Later laws required the remaining refuse-burning equipment to be stopped and sealed. That’s why so many older buildings have a chute but no incinerator.

Yes. Pre-war buildings often have brick or masonry chutes, many of them flues that once fed the building’s incinerator. Rough masonry holds grease and residue in its surface and joints, so it needs more degreaser, more passes and a closer look than a smooth metal chute. Marshall has cleaned both since 1994.

The owner. NYC’s chute rule requires chutes, refuse rooms and hoppers to be kept clean, sanitary and free of vermin and odors, and makes the owner run a treatment program for them. In practice the super handles daily upkeep and a contractor does the deep cleaning. Tenants bag their trash and follow the chute rules.

Yes, for pest treatment. Under 1 RCNY §24-01 the owner must treat the chute, refuse room and related parts as often as needed to prevent insects and rodents, and keep a record of those treatments available for the Department of Buildings. Dated cleaning reports belong in the same file.

Yes. NYC’s Buildings rule 1 RCNY §24-01 requires chute openings to have approved self-closing hoppers that close off the chute while trash is loaded, with hopper doors rated for at least one hour of fire resistance. A door that sticks open or won’t latch defeats that protection.

No. NYC’s chute rule requires refuse room doors to be fireproof and self-closing, rated at least 1½ hours, and says it is unlawful to keep them open. Propping the door for convenience defeats the room’s fire separation.

Generally, yes. The New York State Fire Code calls for sprinklers at the top of rubbish and linen chutes and in their terminal rooms, plus alternate floors where a chute runs through three or more floors, and NYC’s chute rule requires sprinklers in the refuse room. Your engineer can confirm what applies to your building.

We check the parts we work around on every job: intake doors that should close and latch on their own, and sprinkler heads in the chute that should be clear and undamaged. It’s a condition report, not a code inspection. We clean, we don’t repair, so anything that needs fixing gets photographed and reported to you.

Yes. We clean and sanitize linen chutes and work around your operation, including off-hours when that’s easier for housekeeping or environmental services. Hospitals and busy hotels usually need cleaning more often than apartment buildings.

Yes. Hospital infection-prevention policies treat them as part of the cleaning program. UNC Medical Center’s 2024 policy, for example, has laundry chute intake openings cleaned weekly or when visibly soiled with an EPA-registered disinfectant, and requires all linen to be bagged before it goes down the chute.

Every building is quoted on its own. The price depends on the number of floors and chutes, whether the chute is pre-war masonry or post-war metal, how long since the last cleaning, access and scheduling, and add-ons like graffiti. Call (646) 391-7620 or send the address and Marshall will price it the same day.

All five boroughs of New York City, Long Island and Westchester, plus New Jersey, Connecticut and Pennsylvania. If your building is in the tri-state area, call and ask. Marshall goes where the work is.

Yes. Chute Cleaning Division is insured in partnership with Select Exterminating, and we can send a certificate of insurance for your building or management company on request.

Yes. Many of the buildings whose chutes we clean also call us to remove graffiti from their exterior walls, doors and gates. It’s the same crew and the same standard.

The owner. NYC’s Department of Sanitation says property owners are required by law to remove graffiti from their property or arrange for its removal. If someone reports it to 311, the owner is mailed a Notice of Intent to Remove Graffiti under the Graffiti-Free NYC program.
