Duct cleaning in Old Chiswick
Ductwork cleaning for Old Chiswick and the surrounding area: diagnosis first, then a fixed quote, the work and a report with photos. Ask us for a fixed quote.
- An insurer asking for TR19 evidence
- Years of grease along the duct floor
- Duct runs that can’t be reached
Looking after it afterwards
Results last longer with the right care. Here’s what we suggest:
- Keep access panels clear of stored items
- Do not switch the extract off early
- Ask us about extra access panels where sections can’t be reached
- Have the grease measured if cooking hours go up
You’ll have a recommended date for the next clean, worked out from the grease we found and how long you cook each day, in line with BESA guidance.
Have access panels fitted where sections can’t be reached. It doesn’t stop grease forming, but it stops it building unseen.
How we handle ductwork cleaning in Old Chiswick
Duct Doctor has cleaned kitchen extract ductwork since 2009, working across London and the South East. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, with each certificate issued through the BESCA portal. If you are dealing with hardened, baked-on grease in long horizontal runs and readings above 200 microns from a grease thickness test, we can put it right, from horizontal duct runs, multi-storey ducts and attenuators onwards.
Kitchens in Old Chiswick, like many across London, can share a building with flats or offices, with the duct running up through shared risers. A duct fire there can reach parts of the building far from the range, which is why keeping it clean to TR19® matters.
The report is your system’s health record: dated, with pictures, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

What ductwork cleaning cannot fix
Not every problem is solved by ductwork cleaning, and we’d rather say so up front. It will not put right:
- Sections that can’t be reached safely without new access (those are recorded, and panels can be fitted)
- Leaking duct joints that need repair
- Undersized or badly laid-out ducts
Not sure which it is? You can ring 0345 646 2711 or drop us a line and we will tell you honestly.
Parts of the system we cover
- Bends and junctions
- Access panels
- Attenuators
- Horizontal duct runs
- Vertical risers
- Multi-storey ducts
In-house cleaning or a specialist?
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.
Landlords, agents and facilities managers
Keeping records across a portfolio is half the battle. Each visit ends with a dated report and pictures, ready to show insurers, fire officers or EHOs.
Multi-site operators often want one contractor and one number. We cover South East England and London, so visits at different addresses can be planned together and kept on a regular cycle.
Old Chiswick kitchens: local notes
The FSA’s food hygiene register shows about 474 restaurants, cafés and works canteens and about 94 sandwich bars and takeaways within about 1.5 miles of central Old Chiswick. Wherever those kitchens cook under a canopy, the horizontal runs and risers need cleaning as well as the hood. The fire and rescue service for Old Chiswick is London Fire Brigade. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel. It’s Hounslow council that sends environmental health officers to food businesses in Old Chiswick. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Keeping each certificate and photo report on file helps show the extract is looked after.
For schools such as The William Hogarth Primary School, kitchen extract cleaning is normally booked for the holidays, when the canteen is closed. Healthcare kitchens, like those at hospitals such as West London Hospital (about 1.3 miles east), often cook for long hours, which puts them in BESA’s heavier-use bands.

What else we do in Old Chiswick
What happens if it’s left?
There’s no law that names TR19. The Fire Safety Order 2005 makes the responsible person assess and reduce fire risk, including the grease inside the extract ductwork. London sites work long hours, and the longer a job is left, the bigger it gets.
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re unsure, phone us on 0345 646 2711 or use the quote form and we will give you an honest view and a fixed quote.

Signs you need ductwork cleaning in Old Chiswick
Grease in a duct running from a kitchen in Old Chiswick is as much a fire risk as in any building. Once it lights, fire can spread along the duct and into other areas, which is why the responsible person needs it under control.
These are the problems we see most often:
- Thick deposits at the bottom of a vertical duct
- Thick crusts of old grease along the duct
- A duct clean needed for an insurer
- Readings above 200 microns from a grease thickness test
A kitchen near Chiswick station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval.
What your quote should include
- What paperwork you get at the end
- How areas they cannot reach will be recorded
- If they look at the system before pricing
- When the next visit should be, and why
Questions from Old Chiswick
Which environmental health team covers Old Chiswick?

Who is the fire and rescue service for Old Chiswick?
It’s London Fire Brigade, which covers Old Chiswick. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
How often does extract ductwork need cleaning?
It depends mostly on daily cooking hours. Kitchens cooking 12 to 16 hours a day need it at least every 3 months, while lighter use can go longer.

BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t legislation, but it’s the standard people check against.

What we do, step by step
We’re used to working while the site is closed. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. On site, the work takes a few hours for a short run, longer for long runs and tall risers. Most London sites cannot stop for the day, so work in Old Chiswick is typically done overnight, early in the morning or at weekends.
- We trace the duct and find every way in.
- Grease thickness is measured at set points.
- Once the kitchen has closed, we protect the area and open the panels.
- Heavy deposits come out by hand, then each section is degreased.
- We close up, re-test, photograph and record anything out of reach.
Before we arrive
- Mention any parking or loading restrictions
- Arrange a key holder or contact on site
- Tell us about site rules, permits or sign-in
