What you can see at the canopy is only half the system. Grease vapour that escapes the filters condenses and hardens along the ductwork — in the horizontal runs, the bends and the risers you can't easily reach. That hidden layer is exactly where extract fires take hold and spread.
We arrange complete ductwork cleaning quotes for Swansea kitchens, covering the full run from canopy to external discharge, with grease-depth checks before and after.
What's involved
Specialists open up the full run — adding access hatches where there aren't any — and mechanically clean every section through to the discharge terminal. Readings and photographs at the access points go into your compliance certificate.
Why it matters here
Fire-risk assessors look specifically at ductwork, because a canopy-only clean leaves the most dangerous grease in place. A documented full-system clean is what demonstrates real TR19 compliance.

Frequently Asked Questions
Do you clean the whole duct run?
Yes — out to the external discharge. Where sections aren't accessible, providers fit hatches so the whole run can be reached and cleaned.
How is the clean proven?
Pre and post grease-depth readings plus photographs are recorded and included in your certificate.
