The ductwork is the hidden half of your extract system — and often the most dangerous. Grease vapour that isn't captured at the canopy condenses and hardens along the duct run, building up in horizontal sections, bends and risers where you can't see it. This is exactly where extract fires start and spread.
We arrange complete ductwork cleaning quotes for Cardiff commercial kitchens, covering the full run from the canopy to the external discharge point, with grease-depth assessment before and after.
What's involved
A proper duct clean means accessing the full run — adding inspection hatches where needed — and mechanically cleaning every section: horizontal ducting, risers, bends and the discharge terminal. Pre and post grease readings confirm the system has been brought back to standard, and the work is photographed and certified.
Why it matters for Cardiff kitchens
Insurers and fire-risk assessors specifically look at ductwork because a canopy-only clean leaves the highest-risk grease in place. A documented full-system clean is what demonstrates genuine TR19 compliance.

Frequently Asked Questions
Do you clean the full duct run or just the accessible bits?
We arrange cleaning of the complete run to the external discharge. Where sections aren't accessible, providers fit inspection hatches so the whole system can be reached and cleaned properly.
How do you prove the ductwork is clean?
Pre and post grease-depth readings plus photographs at access points are recorded and included in your compliance certificate.
