Grease Duct Cleaning in Denver, CO: The Hidden Half of Kitchen Exhaust Cleaning
The grease duct runs out of sight from the hood to the roof, which is how buildup goes unnoticed. Denver Hood Cleaning Co cleans accessible duct runs, tells you what could not be reached and works with your building's access panels.
Cleaning the Duct You Cannot See
Accessible duct runs degreased, with clear notes on access panels and what we could not reach.Grease vapor that passes the filters settles inside the duct. Cleaning it depends on reaching it, which is why access panels and building layout shape the scope of every duct job.
Survey and Access
Before cleaning, we work out where the duct goes and where we can get into it.
Route review:
Horizontal and vertical runs are identified, including any that pass through other floors or tenants.
Access panels:
We locate existing panels and note where more would be needed to clean the full run.
Landlord coordination:
Where panels or shared space need approval, we tell you early so it does not stall the visit.
Degreasing the Duct
The cleaning itself works from the hood connection toward the fan.
Scraping and degreasing:
Buildup is removed from accessible surfaces, working toward clean metal.
Containment:
Grease and rinse water are kept out of the kitchen and collected for handling.
Closing up:
Panels are resealed, and damaged or missing ones are noted in the report.
Multi-Floor and Older Buildings
Many Denver restaurants sit in older or mixed-use buildings where the duct was never designed for cleaning.
Long vertical runs:
More floors mean more access points, more time and sometimes coordination with other tenants.
Converted buildings:
Ducts in chases or shared walls may be harder to reach, and we say so before quoting.
Honest reporting:
The report lists what was cleaned and what could not be reached, so you know the real state of the system.
How We Plan Duct Cleaning
A duct job is mostly planning: where the duct goes, how we reach it, and how we keep grease contained while we work.
Contained Work:
Containment keeps grease and rinse water out of your kitchen and off your floors.
Plain Reporting:
If a section cannot be reached, we write that down rather than imply the full run was cleaned.
Paired With Hood Service:
Duct visits are often scheduled with hood and fan cleaning so the whole system is on one calendar.
What to Expect from a Duct Cleaning
Duct cleaning is quieter than hood cleaning but needs more planning. Here is what we agree on first.
Access Confirmed:
We agree on which panels we will use and who provides access to shared or upper floors.
A Clear Window:
We coordinate scheduling around your service hours, and we tell you if the job needs more than one visit.
A Written Record:
You get a service report listing the sections cleaned and any access issues found.

Grease Duct Cleaning for Denver Commercial Kitchens
The grease duct is the hidden part of the exhaust system: the ductwork that runs from the hood up through the ceiling, a wall chase or several floors to the roof fan. Because it is out of sight, buildup can accumulate for years without anyone noticing, and it is the part that fire codes focus on most when they describe cleaning to bare metal.
Below is a general overview of duct cleaning in Denver buildings. Requirements differ, so confirm with your fire inspector and your insurer.
Why access panels matter
Duct cleaning depends on being able to reach the duct. NFPA 96 expects access panels at specific locations, and where there are too few, a thorough cleaning is difficult. If your duct has no access, we note it and discuss adding panels with your landlord or a qualified contractor.
Multi-story and mixed-use buildings in Denver often have long vertical runs, which means more panels, more time and sometimes coordination with other tenants.
What duct cleaning typically includes
- Survey: locating the duct path and access panels, and noting horizontal and vertical runs.
- Degreasing and scraping: removing buildup from accessible duct surfaces, working toward clean metal.
- Containment: keeping grease and cleaning water out of the kitchen and the building.
- Closing up: resealing access panels and noting any that are damaged or missing.
- Documentation: a service report listing what was cleaned and any sections that could not be reached.
Older and converted buildings
Many Denver restaurants occupy older brick buildings that were converted from other uses. Their ducts may run through chases that were not designed for cleaning, and they can share space with other trades. We assess what is reachable before quoting rather than promise a full-length clean on an unknown system.
What affects duct cleaning scope
- Length and floors: more duct and more floors mean more access points and more time.
- Grease level: heavier buildup takes longer to remove.
- Access panels: missing or hard-to-reach panels limit what can be cleaned.
- Schedule: work after close or on a quiet day affects planning and cost.

Grease Duct Cleaning FAQs for Denver Kitchens
It is the exhaust ductwork that carries grease-laden air from the hood to the rooftop fan. It is separate from the building's general HVAC ducts and is built to handle grease vapor.
You usually cannot tell from the kitchen. Commonly cited NFPA 96 guidance bases cleaning on the interval for your cooking type and on inspection of the system. A written inspection from a service visit is the better indicator.
We note it in the report and explain what could not be reached. Adding access panels is typically a job for a qualified contractor and may need your landlord's approval.
We assess access first. Long vertical runs need panels at suitable points and sometimes coordination with other tenants, and we say plainly what is reachable before the work starts.
We use containment so that grease and wash water stay controlled, and we clean up before we leave. Expect some prep, such as clearing the line and covering equipment.
It depends on duct length, floors, access and grease level. We give an expected window after reviewing your system, and we are upfront if the scope looks like it needs more than one visit.
