Best Exhaust Cleaning in Sydney: How to Choose a Contractor

The single biggest difference between exhaust cleaning quotes in Sydney is scope, not price. A quote for "exhaust cleaning" can mean the filters alone or the entire system to the roof — and the two are separated by thousands of dollars and most of the fire risk.

The short answer

The best commercial exhaust cleaning contractors in Sydney clean the entire system rather than the reachable parts of it: canopy, filters, the full duct run including risers and bends, and the discharge fan. They measure airflow before and after, fit compliant access panels where the run cannot be reached, document the work to AS 1851, and assess the installation against AS/NZS 1668.1.

The checklist

What to look for — and why each one matters

Use this as a script. Every item is a question you can ask before you book anyone.

Criterion 1

Full-system scope, stated in writing

What to look for
A quote that itemises canopy, filters, duct run (with length), riser, fan and discharge cowl separately.
Why it matters
Grease left in the duct recontaminates a cleaned canopy within weeks. Partial cleaning buys you a clean-looking kitchen and an unchanged fire load.

Expert Exhaust Cleaning: Every quote itemises the full system, and states plainly which sections are excluded and why.

Criterion 2

Access panels fitted, not cleaned around

What to look for
Ask what happens to duct sections with no access. The answer should be "we fit panels".
Why it matters
A duct section that cannot be reached cannot be cleaned or inspected — and a certificate covering it would be worthless. Contractors who clean around missing access are certifying work they did not do.

Expert Exhaust Cleaning: Compliant sealed access panels are fitted at the intervals the run requires, quoted up front.

Criterion 3

Airflow measured before and after

What to look for
A recorded reading on the service report, not a verbal "it’s much better now".
Why it matters
Airflow is the only objective measure of whether extraction actually improved. Heavily loaded systems commonly lose 20–30% of rated airflow, and you should see that recovered as a number.

Expert Exhaust Cleaning: Pre- and post-clean airflow readings recorded on every fan and full-system clean.

Criterion 4

Assessment against AS/NZS 1668.1

What to look for
A contractor who will comment on duct sizing, discharge location and fire dampers — not only on grease.
Why it matters
Cleaning cannot fix a system that was installed wrong. Knowing that your discharge is too close to an intake is worth more than another clean.

Expert Exhaust Cleaning: Every full-system clean includes an AS/NZS 1668.1 assessment, with non-compliances listed in writing.

Criterion 5

Trade-waste disposal of grease

What to look for
Ask where the grease and caustic waste goes.
Why it matters
Grease flushed to stormwater is an offence that traces back to the site, not just the contractor. It is also a straightforward indicator of how the rest of the job is run.

Expert Exhaust Cleaning: All waste captured and disposed of as trade waste. Nothing enters stormwater.

Criterion 6

Named technicians and a signed report

What to look for
A report signed by the person who did the work, not an unattributed office-generated PDF.
Why it matters
Accountability. Subcontracted labour with no name on the paperwork means nobody is answerable when a section is missed.

Expert Exhaust Cleaning: Sydney-based employed crews. The technician who cleans your system signs the report.

We meet every criterion above, and we will put each one in writing before you book — insurance certificate, sample AS 1851 report, technician certifications and a fixed scope.

Questions buyers ask before booking

FAQ

Direct answers you can act on.


What does commercial exhaust cleaning actually include?

A complete exhaust clean covers the canopy and filters, the full duct run from the canopy plenum to the roof discharge including risers and bends, and the exhaust fan and discharge cowl. Anything less should be described in the quote as a partial clean.

How much does commercial exhaust cleaning cost in Sydney?

Between $900 and $1,600 for a single-canopy system with a short duct run, $1,600–$2,800 for two canopies on a shared run, and $3,000–$6,000 for a multi-storey riser. Access panel installation and difficult roof access are the two most common price variables.

How do I know the duct was actually cleaned?

Ask for photographs taken at each access point, before and after. A contractor cleaning the full run will have opened the duct in several places and can show you inside each one.

Should exhaust cleaning be done during the day or overnight?

Overnight, in almost all cases. Daytime cleaning costs a full service period, and caustic degreasers should not be in use above a working cooking line.
