"Canopy cleaning," "duct cleaning," "extract cleaning" — the terms get used loosely. Here's what each part actually is and why a proper clean covers all three.
The canopy
The canopy (or hood) is what you see above the cooking line. It captures grease, steam and heat, and holds the baffle filters. It's the most visible part — and the easiest to clean — but it's only the start of the system.
The ductwork
Behind the canopy, the ductwork carries the extracted air to the outside. Grease that escapes the filters condenses and hardens along this run — in horizontal sections, bends and risers you can't see. This hidden layer is where most extract fires start and spread, which is why TR19 places so much emphasis on cleaning the full duct to the external discharge.
The fan
At the end of the run, the extraction fan pulls the air out. A grease-clogged fan moves less air, works harder and adds to the fire risk, so it's cleaned alongside the rest.
Why a full-system clean matters
A canopy-only clean leaves the most dangerous grease — in the ductwork — in place. That's why a TR19 extract clean covers canopy, duct and fan together, with readings and photos to prove the whole system was done. Request a free quote.
Frequently Asked Questions
Is canopy cleaning enough on its own?
No — it leaves the higher-risk grease in the ductwork. A full TR19 clean covers canopy, duct and fan.
How do you reach the ductwork?
Specialists add inspection hatches where needed so the full run can be accessed, cleaned and photographed.
