Hood Cleaning & Grease Trap Pricing in Rapid City — Published, Not Hidden
A single-hood kitchen exhaust cleaning in Rapid City typically runs $300–$700 per service. A multi-hood line runs $800–$1,500. An indoor grease trap pump-out runs $150–$450 per visit. Those are real working ranges from published national cost data, and the rest of this page breaks down what moves a job inside them — because the standard industry move is to hide every number behind a sales call, and we’d rather you walk into the quote knowing what fair looks like.
One sentence governs everything below: price depends on hood count, duct run length, roof access, grease load, and trap size — and a free walkthrough gets you a firm quote.

What moves the hood cleaning number
Hood count. Each additional canopy adds filters, plenum, and duct to the scope. A four-hood hotel line is a different night than a single-hood taco kitchen, which is why the multi-hood range starts where the single-hood range ends.
Duct run length and geometry. A short vertical duct straight to a roof fan cleans fast. A long horizontal run with elbows and limited access panels takes real time — every foot has to reach bare metal, not just the parts a camera can see from the hood. Long runs are the most common reason a quote lands at the top of the range.
Roof access. A one-story building with a fixed ladder is simple. A steep-pitch roof, an interior-access-only hatch, or a downtown building where staging takes planning adds labor before the first bolt comes off the fan.
Grease load. A system on a regular cadence cleans predictably. A system that’s gone a year past due — common when a restaurant changes hands — carries baked-on load that takes hours of extra scraping. First services on neglected systems price high; the follow-ups get cheaper because the cadence is right. The restaurant hood cleaning page covers what a full-scope service includes.
Cooking style. Solid-fuel and charbroil operations produce heavier, stickier deposits and sit on the fastest inspection schedule NFPA 96 has — monthly for solid fuel, quarterly for high-volume. More visits per year, more load per visit, top of the range. Details on why in the NFPA 96 compliance guide.
What moves the grease trap number
Trap size and type. Indoor under-sink traps run 20–100 gallons and price at $150–$450 per visit; getting on a recurring route brings the floor to roughly $125. In-ground interceptors — the 500 to 3,000-plus gallon concrete vaults outside — are a vacuum-truck job at roughly $325–$950 up to about 1,000 gallons, with bigger vaults quoted individually. See grease trap pumping and interceptor service for scope details.
Condition. A trap pumped on the 25% rule — the industry practice of pumping when fats, oils, grease, and solids reach a quarter of capacity — pumps quickly. A trap that’s fully capped with hardened grease takes longer and can need extra work on the lines. Rapid City doesn’t codify a pumping interval; the ranges above assume a trap that’s been on some kind of schedule, and we’ll tell you during the walkthrough if yours hasn’t.
One thing you won’t see here: per-gallon pumping rates quoted as fixed facts. Nobody publishes reliable ones, and any vendor quoting a hard per-gallon number is deriving it on the spot. We quote the visit.
Why rush work costs more — and how to never pay it
Pre-inspection panic service carries a 25–50% premium because it means a crew re-shuffling a full overnight schedule on short notice. It’s the most avoidable cost in this trade. A kitchen on the right NFPA 96 cadence — inspections on the Table 12.4 schedule for its cooking volume, cleaning when the inspection finds the threshold — never needs rush service, because the dated sticker on the hood is always current when the fire inspector walks in.
The Black Hills calendar sharpens this. Summer tourist volume and the August rally load systems fast, and pre-season slots in April and May book out. A spring deep clean at the normal rate beats a July emergency at a premium — same work, different invoice. Kitchens in Sturgis especially: the pre-rally window is the busiest fortnight of the year, and early booking is the whole game.
What the price includes
Every full exhaust cleaning in these ranges includes the compliance product, not just the labor: hood canopy, baffle filters, plenum, accessible ductwork, and the rooftop fan cleaned to the bare-metal standard, plus before-and-after photos, a written service report, and a dated certification sticker on the hood. That documentation set is what the Rapid City Fire Department’s inspectors ask to see and what insurance carriers request after an incident. A cheap quote that skips the fan or the paperwork isn’t a deal — it’s half a service, and the half that’s missing is the half the fire code cares about.
Grease trap and interceptor visits include full pump-out (not skimming), a look at inlet and outlet tees, and a disposal manifest for your records.
How to compare quotes — the scope checklist
If you’re shopping this around (you should — published ranges make that easy), compare scope before price. Five questions expose the difference between a compliance service and a canopy wipe:
- Does the quote include the duct run and the rooftop fan, or does “hood cleaning” stop at the filters? The fan and duct are where the fire code’s attention actually lives.
- What’s the cleaning endpoint? The right answer references bare metal and the ANSI/IKECA C10 method standard — not “degreased” or “washed.”
- Who holds what certification? South Dakota has no state hood-cleaner license, so IKECA credentials (CECS, CECT) are the screening question. A vendor who can’t name a certification, or names one that sounds invented, has answered the question anyway.
- What documentation is included? Photos, written report, dated sticker — all three, in the base price, or the quote is incomplete.
- On traps: pump-out or skim? A full pump-out removes grease, water, and solids; a skim leaves the solids and most of your problem. The cheap trap quote is usually the skim.
A low bid that fails two of these questions isn’t a low bid — it’s a smaller job wearing your job’s name. Every range on this page assumes the full-scope version, because that’s the only version that produces paperwork worth showing an inspector.
Getting your number
Ranges are honest, but your kitchen is specific.

If you’re comparing vendors, take our FAQ with you; the questions about certification, scope, and paperwork are the ones that separate a real NFPA 96 service from a canopy wipe-down.
