Hood Cleaning & Grease Trap Pricing in Sioux Falls — Published, Not Hidden

A single-hood exhaust system cleaning in Sioux Falls typically runs $300–$700 per service, a multi-hood line (2–4 hoods) runs $800–$1,500, and an indoor grease trap pump-out runs $150–$450 per visit. Most companies in this trade make you sit through a walkthrough before they’ll say a number out loud. Here’s the whole table up front, then an honest explanation of what moves each line — because the walkthrough should confirm your price, not reveal it.

The full price table

Price depends on hood count, duct run length, roof access, grease load, and trap size — a free walkthrough turns the range into a firm quote.

What moves the hood-cleaning number

Hood count. The first hood carries the mobilization — truck, crew, containment setup, roof access. That’s why a second and third hood on the same line cost less per hood than the first, and why the 2–4 hood band runs $800–$1,500 rather than a straight multiple of the single-hood price.

Duct run length. A single-story building with a short vertical duct to the fan is the easy version. A downtown Sioux Falls building where the duct climbs two or three stories through the structure is a different job: more interior surface to scrape and wash, more access panels to open, more time on ladders. Duct run is usually the biggest spread between two kitchens with identical hoods.

Roof access. Crews reach the fan by roof hatch, exterior ladder, or lift. A locked hatch nobody has keys to at 1 a.m., a steep or iced roof in a Sioux Falls January, or a fan mounted somewhere that needs staging all add time. A hinge kit ($150–$300 installed) pays for itself here — it lets the fan tip open for full cleaning in minutes instead of being wrestled off its base every visit. Details on the exhaust fan service page.

Grease load. A system inspected and cleaned on the cadence NFPA 96 Table 12.4 implies for your cooking volume never gets truly bad, and pricing stays at the friendly end. A system that’s gone a year past its interval — hardened, baked-on grease through the plenum and duct — takes hours more scraping to reach bare metal, and the first cleaning is priced accordingly. Every kitchen that’s ever been quoted a painful “catch-up clean” learned the same lesson: the standing schedule is the cheap option.

Cooking style. Solid-fuel and heavy 24-hour systems sit at the high end and on the tightest cadence — monthly inspection for solid fuel, quarterly for high-volume lines — because charbroilers, woks, and around-the-clock frying load the system fastest. The restaurant hood cleaning page covers what full-system service includes at any volume.

What moves the grease-trap number

Trap size and type. An under-sink or indoor floor trap (20–100 gallons) is a $150–$450 visit; an in-ground interceptor up to around 1,000 gallons runs roughly $325–$950. Bigger vessels mean more volume to pump, haul, and dispose of legitimately — the manifest you get afterward is part of what you’re paying for.

Route vs. one-off. A kitchen on a recurring pump-out route can see per-visit pricing floor around $125 for small indoor traps, because the hauler’s truck is already in the neighborhood on a schedule. One-off emergency pump-outs — the Saturday the floor drain backs up — price like emergencies.

Why the schedule matters here too. Sioux Falls doesn’t codify a pumping calendar; the city’s lever is a sewer surcharge when discharge exceeds 100 mg/L of grease under §51.081(d). The industry practice — an EPA-recommended best practice, not a city ordinance — is the 25% rule: pump when grease and solids fill a quarter of the trap’s capacity. A trap past that point stops holding grease back, and the surcharge math gets worse than the pumping bill fast. Full breakdown on the grease trap pumping and grease interceptor pages.

The rush premium, explained without judgment

Pre-inspection rush service — the fire inspector is coming Thursday and the sticker on the hood is a year old — runs 25–50% above standard pricing. Not as a penalty; it’s what it costs to reshuffle an overnight crew’s route on short notice. Every kitchen ends up here once. The way out is the standing schedule: quarterly or semiannual service booked in advance, always overnight, priced at the standard rate, with the dated sticker and report refreshed before anyone official asks. That schedule logic is laid out on the NFPA 96 compliance page.

What’s included at every price point

Whatever the number, a proper service includes the same deliverables: the full system cleaned to the bare-metal standard (residual combustible residue no more than 0.002 inches), before-and-after photos including the duct interior and fan, a written service report, and a dated certification sticker on the hood. On the trap side: a full pump-out (not a skim), a look at inlet and outlet tees, and a disposal manifest for your records.

If a low bid doesn’t include the duct and fan, it isn’t a lower price for the same service — it’s a different, smaller service that leaves the fuel load in the part of the system you can’t see. The photos are how you tell the difference between the two, which is why we treat them as non-negotiable.

Multi-location and satellite-town pricing

The ranges above hold across the metro — Brandon, Harrisburg, Tea, and Dell Rapids price the same as a Sioux Falls address, since a 15-minute drive doesn’t change the work. Groups running several locations can put all of them on one route and one report format, which tends to earn route pricing on the trap side and keeps every kitchen’s paper trail consistent for whichever health authority licenses it.

How to read a competing bid

Two habits make you a hard customer to underquote-and-underdeliver. First, make every bid itemize scope against the same checklist: canopy, filters, plenum, full duct run, fan opened and degreased, wash water hauled away, photos of the duct interior and fan included. A number without that list attached isn’t comparable to one with it. Second, ask what happens when the crew finds a problem — a missing duct access panel, a fan that can’t open, a burned-through filter. The right answer is “it gets photographed and flagged in the report with a price to fix it,” not silence. Bids that survive both questions tend to land inside the ranges above; bids that don’t are usually cheaper for a reason you’d have paid for later.

Getting your number

The walkthrough is free and takes about twenty minutes: hood count, duct run, roof access, cooking volume, trap size and location. You get a firm quote — not a range, not “starting at.” Call (605) 675-7391 or send the form, and if you want the code background before you buy anything, start with the FAQ.
