Service-Tech Corporation provides kitchen exhaust hood cleaning in Columbus, OH — complete grease removal from the hood, filters, ductwork, and exhaust fan, cleaned to bare metal per NFPA 96 and documented for the fire marshal and your insurance carrier. An IKECA member serving the Columbus market since around 1980 from our Gahanna office, we clean for the full spread of central Ohio kitchens: restaurants and restaurant groups, hotel and banquet operations, hospital food service, corporate cafeterias, and campus dining at OSU scale.
Full-System Scope: Hood, Duct, Fan, Roof
NFPA 96 governs the exhaust system, not the canopy — so a compliant cleaning covers the entire grease path:
- Hood canopy and plenum — scraped and pressure-washed to bare metal
- Grease filters — cleaned and reseated, with damaged filters flagged for replacement
- Horizontal and vertical ductwork — the concealed runs where the heaviest grease lives and where duct fires propagate
- Exhaust fan — blades, housing, and hinge access, tipped and cleaned properly on the roof
- Rooftop grease containment — the grease field around the fan handled before it becomes a roofing and slip hazard
- Certification documentation — service sticker plus a report with before/after photos, per IKECA practice
Vendors who quote low and clean the visible hood are common in every market; the duct run they skip is the actual fire path. Our scope is the system, every visit. Full technical depth: the kitchen exhaust hood cleaning service hub.
NFPA 96 and Who Enforces It in Ohio
Ohio's fire code adopts NFPA 96's requirements for commercial kitchen exhaust, which makes cleaning frequency enforceable law rather than a voluntary practice — checked by local fire marshals across Columbus and Franklin County suburbs during inspections, and checked again by insurance underwriters when policies renew or claims land. The inspection conversation is short: current service sticker, certification documentation, evidence the full system (not just the hood) was cleaned. Fail it, and outcomes range from re-inspection orders to shutdown of cooking operations; have a post-fire investigation find a lapsed schedule, and the insurance conversation becomes far more expensive than any cleaning contract.
Cleaning Frequency by Cooking Operation
NFPA 96 keys inspection frequency to what and how much you cook:
| Cooking operation | NFPA 96 frequency | Columbus examples |
|---|---|---|
| Solid fuel (wood, charcoal) | Monthly | Wood-fired pizza and smokehouse operations |
| High-volume (continuous charbroiling, wok) | Quarterly | Stadium and arena concessions, hospital kitchens on continuous service, high-output grills |
| Moderate volume | Semi-annually | Most full-service restaurants, hotel banquet kitchens, corporate cafeterias |
| Low volume (churches, seasonal, day camps) | Annually | Seasonal venues, low-use institutional kitchens |
Most Columbus restaurants land in the semi-annual band; campus, hospital, and event-venue kitchens typically run quarterly. We confirm your classification at the free assessment and build the contract calendar to it — so the schedule itself becomes your compliance evidence.
From OSU-Scale Dining to Multi-Site Restaurant Groups
Columbus is an institutional food-service town: one of the nation's largest campus dining operations, a full calendar of stadium and arena events, hospital systems feeding patients and staff on continuous meal cycles, and fast-growing restaurant groups running kitchens across the metro. That buyer profile — many hoods, many buildings, one responsible director — is who our Columbus practice is built for:
- Campus dining portfolios — dozens of hoods across dining halls, cleaned on academic-calendar windows with consolidated per-building documentation
- Stadium and arena concessions — high-volume, event-compressed schedules; every stand certified before the season opens
- Hospital and senior-living food service — continuous-operation kitchens cleaned in coordination with meal service and infection-control expectations
- Hotel and conference banquet kitchens — swing-load operations scheduled around the events calendar
- Multi-site restaurant groups — every location on one contract, one frequency map, one reporting format
One Portfolio, One Compliance Picture
The hardest part of multi-site hood compliance isn't the cleaning — it's the paperwork sprawl. Ten locations with three different vendors means three sticker formats, three report styles, and no single answer to the question "are we compliant everywhere, right now?"
Service-Tech consolidates that picture. Every location gets the same full-system scope, the same bare-metal standard, and the same certification report format — so your compliance file reads identically from your Polaris location to your downtown flagship. And because our footprint pairs Columbus with Cleveland and Dayton offices, an Ohio restaurant group or multi-campus operator can put its whole state portfolio under one vendor, one frequency map, and one accountable contact — with kitchen exhaust hood cleaning in Cleveland and kitchen exhaust hood cleaning in Dayton handled by the same company on the same standard.
How a Hood Cleaning Visit Runs
- 01
Pre-inspection
scope confirmation, grease-depth check, and scheduling coordination with your kitchen manager
- 02
Protection
cooklines, equipment, and floors sheeted before any grease moves
- 03
Hood-to-fan cleaning
hot-water pressure washing and hand scraping to bare metal through hood, plenum, duct, and fan
- 04
Rooftop service
fan exterior and grease containment addressed, not skipped
- 05
Filter service
cleaned, reseated, damage flagged
- 06
Certification and closeout
sticker applied, report with before/after photos delivered, deficiencies (like missing access panels) documented with a fix quoted
Operating kitchens are cleaned when they aren't cooking — overnight and off-hours windows are standard, sequenced across multi-hood sites so no service period is touched.
The Acceptance Checklist: How to Sign Off Any Vendor's Hood Cleaning
Whether you hire us or not, hold every hood-cleaning vendor to this five-minute walkthrough before signing:
- Look for metal, not shine. Open an access panel: interior duct surfaces should show bare metal, not a thinned, evened-out grease film
- Check the roof. The fan should be clean inside its housing, and the surrounding roof free of fresh grease trails
- Count the photos. Before/after photos should cover the same points every visit — plenum, duct panels, fan, roof — not just the prettiest angle
- Read the deficiency list. A system with inaccessible duct sections should have them documented, with access-panel installation quoted — a report with zero deficiencies on an aging system is a red flag, not a compliment
- File the certificate. Sticker on the hood, certification report in your compliance file, next service date on the calendar
That checklist is simply our own closeout standard, written down. If your current vendor's work can't pass it, you have your answer.
Opening a New Kitchen? Start the Compliance File on Day One
Columbus adds restaurant seats every year, and new operations have a compliance moment most first-time owners miss: the exhaust system needs its baseline service and documentation before the grease ever gets ahead of you. A new kitchen's first cleaning is quick and inexpensive — the system is nearly clean — but it establishes three durable assets: your NFPA 96 frequency classification confirmed against your actual cookline, a photo-documented baseline your future cleanings are compared to, and a compliance file that exists before your first fire-marshal visit rather than because of it. Get the first service scheduled during your soft-opening window and the calendar runs itself from there.
What We Find in Central Ohio Exhaust Systems
The deficiency patterns in Columbus kitchens track the city's food-service growth — fast build-outs, converted spaces, and equipment upgrades that outran their exhaust systems:
- Duct runs with no access panels — common in converted retail and strip-center build-outs, where the exhaust duct threads through structure nobody planned to open again. Uncleanable means non-compliant; we document it and quote the panels.
- Fans without hinge kits — a fan that can't tip open can't be fully cleaned, and "cleaned as far as reachable" is not a certification worth filing.
- Upgraded cooklines on legacy schedules — a kitchen that added a charbroiler or moved to higher-volume service has moved up an NFPA 96 frequency class, whether or not its cleaning contract noticed.
- Rooftop grease with no containment — the membrane damage is invisible from inside the restaurant and very visible in the landlord's roof-inspection photos.
- Sticker-only histories — a current sticker with no photo-documented reports behind it protects nobody in a post-fire insurance review.
Every finding lands in your closeout report with a recommended fix and, where relevant, a quote — so the deficiency list shrinks year over year instead of waiting for an inspector to write it for you.
What Hood Cleaning Costs in Columbus
Kitchen exhaust hood cleaning starts at $599 per cleaning. Recurring compliance contracts — the norm for institutional and multi-site buyers — are quoted per site after a free assessment, with pricing driven by hood count, duct length and configuration, roof access, and grease load. Travel is factored into the quote; no separate surcharge, whether the kitchen is in Gahanna or ninety minutes out. Portfolio contracts price per location after each site's assessment, so growing groups add kitchens to the schedule without renegotiating the relationship.
The Failure Modes of a Greasy System
Grease-loaded exhaust fails in predictable ways: the duct fire that turns a cookline flare-up into a structure fire; the failed inspection that becomes a shutdown order in your busiest month; the post-loss insurance investigation that finds the lapsed schedule and disputes the claim; the rooftop grease slick that becomes some contractor's fall. Each one costs a multiple of a cleaning contract. None of them happens to kitchens that keep the NFPA 96 calendar — which is why the calendar, held by one accountable vendor and evidenced by one consistent report format, is the whole strategy.

What Your Scope of Work Should Specify
Campus dining, corporate cafeterias and distribution-centre canteens dominate Columbus, and they share a scheduling problem: a fixed service window, every day, with no dark night. Cleaning to bare metal around that means working the small hours and having the system back before breakfast service.
- The measurement that decides it. A grease depth comb gauge reading of 0.002 in requires the entire exhaust system cleaned; 0.078 in means clean now.
- Frequency basis. NFPA 96 Table 11.4 sets the minimum by cooking volume — write the contract against the table, not against a calendar habit.
- Scope to insist on. Hood interior, filters and baffles, the full duct run, fan housing and blades, and the rooftop termination.
- Prohibited. Coating a cleaned surface, and any flammable solvent as a cleaning aid. Electrical is locked out before work starts.
- The roof. Grease containment at the fan protects the membrane, and membrane repair is the expensive half of neglect.
What "Bare Metal" Takes on a Loaded System
On a system that has run past its interval, chemistry alone will not get there. Crews isolate the section, pull and soak the baffle filters rather than wiping them in place, shroud the fan before wash-down, then scrape the hardened deposit mechanically before degreasing and hot-washing the surface. Runoff is squeegeed to containment rather than left to find the roof drain, and the accessible stainless is polished at the end so the next inspection starts from a known baseline. That sequence is the difference between a system cleaned to the standard and one cleaned to the eye.
Frequently Asked Questions
How often does NFPA 96 require hood cleaning for my Columbus kitchen?
It depends on your cooking operation: monthly for solid-fuel cooking, quarterly for high-volume operations like continuous charbroiling and event concessions, semi-annually for moderate-volume kitchens (most full-service restaurants), and annually for low-volume operations. We confirm your classification during a free assessment and build the contract calendar to match.
Can you handle all of our locations across Ohio?
Yes — that's a core strength. With staffed offices in Columbus, Cleveland, and Dayton, we put multi-site restaurant groups, campus operations, and hospital systems under one contract, one frequency map, and one certification report format statewide, so your compliance file reads identically at every location.
Do you clean campus and stadium kitchens?
Yes. Campus dining portfolios are cleaned on academic-calendar windows with per-building documentation, and stadium and arena concession lines are certified on event-compressed schedules before seasons open. High-volume institutional kitchens are the buyer our Columbus practice is built around.
What does hood cleaning cost in Columbus?
Kitchen exhaust hood cleaning starts at $599 per cleaning. Recurring compliance contracts are quoted per site after a free assessment — hood count, duct length, roof access, and grease load drive the number. Travel is factored in with no separate surcharge.
Will cleaning disrupt our kitchen's service hours?
No. Cleaning is scheduled when the kitchen isn't cooking — overnight and off-hours windows are standard — and multi-hood sites are sequenced so no service period is affected. Scheduling is coordinated with your kitchen manager in advance, not sprung on the closing shift.
What should we check before accepting any vendor's hood cleaning?
Five things: bare metal (not shine) inside duct access panels, a clean fan and grease-free roof, before/after photos at consistent points, an honest deficiency list with fixes quoted, and a certificate plus sticker filed with the next date on the calendar. That's our own closeout standard — hold every vendor to it.
