What is duct cleaning?

Commercial kitchen duct cleaning is the mechanical removal of grease deposits from the entire exhaust duct run between the canopy and the roof discharge point, including risers, horizontal runs, bends and the fan housing.

What’s included

Fixed scope. Everything below is in the price — nothing is an optional extra.

  • Full duct survey — run length, bends, risers and existing access panel positions mapped
  • Compliant access panels installed where the run cannot otherwise be reached
  • Scraping, brushing and rotary-brush cleaning of horizontal runs, risers and bends
  • Fan housing and discharge cowl degreased at the roof termination
  • Grease collected and disposed of as trade waste — nothing flushed to stormwater
  • Before/after photos at every access point plus an AS 1851 cleaning report

Every access point is photographed before and after, and filed with your certificate.

Why it matters

The case for duct cleaning

Three specific reasons, each with the mechanism behind it.

A duct fire travels where the grease goes

Grease deposits inside a duct are continuous fuel running through the ceiling void and up the riser. Once ignited at the canopy, a loaded duct carries fire to the roof and into the building fabric — which is precisely what AS 1851 duct cleaning intervals exist to prevent.

Insurers routinely decline claims on undocumented ducts

Commercial policies commonly require exhaust duct cleaning at a stated interval with written evidence. No report, no cover. We supply a dated AS 1851 report with photographic evidence at every access point.

Build-up quietly strangles extraction

A 3 mm grease lining through a 300 mm duct removes measurable cross-section and adds friction. Extraction drops, the kitchen gets hotter, and the fan draws more power to move less air.

Our process

How we clean: duct cleaning

Same sequence every job, so the result is repeatable and the report means something.

  1. Step 1

    Survey and map the run

    We trace the duct from canopy to discharge, note every bend and riser, and identify where access is missing.

  2. Step 2

    Fit access where needed

    Compliant, sealed access panels are cut and fitted so every metre of the run can be reached and re-inspected later.

  3. Step 3

    Mechanically clean the run

    Scrapers, rotary brushes and degreaser take the internal surface back to metal, working section by section.

  4. Step 4

    Photograph, report, certify

    Every access point is photographed clean, and the AS 1851 report is issued with the technician sign-off.

Duct Cleaning — questions we get asked

FAQ

Direct answers, no runaround.


How much does commercial duct cleaning cost in Sydney?

Commercial kitchen duct cleaning in Sydney typically ranges from $600 for a short single-canopy run to $4,000+ for a multi-storey riser in a shopping-centre food court. Price is driven by duct length, number of bends, roof access difficulty and whether access panels need to be fitted. We quote on site, same day.

How often does a commercial kitchen exhaust duct need cleaning?

Every 3 to 6 months for most commercial kitchens, and as often as monthly for solid-fuel, charcoal or high-volume frying operations. AS 1851 ties the interval to cooking load and observed grease accumulation, so a quarterly inspection is the safe default.

What if my duct has no access panels?

We fit them as part of the job. A duct that cannot be inspected cannot be certified, so compliant sealed access panels are installed at the intervals the run requires — they stay in place for every future clean.

Do you clean the roof fan at the same time?

Yes. The discharge fan and cowl are cleaned as part of a full duct clean, because grease that collects at the termination drains straight back into the run you just cleaned.
