Ductwork Cleaning in West Twyford
Professional ductwork cleaning in and around West Twyford, timed so the site keeps working and signed off in writing with photos.
- High readings at a recent grease test
- Grease pooling at the foot of the riser
- Thick crusts of old grease along the duct
How we handle ductwork cleaning in West Twyford
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, and our certificates are issued through the BESCA Vent Hygiene Elite portal. The work covers attenuators, bends and junctions and horizontal duct runs, and people most often call us about sections of duct with no access panels and readings above 200 microns from a grease thickness test.
In a London area like West Twyford, a kitchen extract often passes through shared space on its way out: a riser, a service void, the floors above. Grease in a duct like that is a fire risk to the whole building, not just the kitchen, which is why keeping it clean to TR19® matters.
We’ve been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

How the job changes from site to site
Attenuators and discharge
The last section of duct before the discharge is often the coolest, which can mean heavier deposits. It’s tested and cleaned along with the rest.
Multi-storey and shared buildings
Long ducts in larger buildings can mean several visits. We agree a sequence that suits the building, out of hours where possible.
West Twyford questions
Do you work overnight in West Twyford?
Yes, evening, overnight and weekend work is normal for us. The work in West Twyford can fit around your hours. Your opening times are the first thing we ask for.
Can a school canteen extract in West Twyford be done out of term time?
Yes. Half-terms and the summer break are the natural time for school work. Around West Twyford, the Food Standards Agency lists about 33 schools and colleges with registered kitchens within a mile and a half or so. Booking early in the term gives the best choice of holiday dates.
What happens if you can’t reach some of it?
We record them on the report, with pictures where possible, and we tell you what would make it reachable, for example new access panels.
Is West Twyford in your area?
Yes. We work in West Twyford and the rest of Greater London, within our South East and London area. To book, give us a ring on 0345 646 2711, or email photos.
What happens if there are not enough access panels?
Without a way in, a section cannot be cleaned properly. We record those sections on the report and can fit access panels.
How do you protect the area?
Protection goes down first: floor sheeting and covers over nearby surfaces and equipment. The area is left tidy, with our waste taken away.
Do we lose a day’s trading?
Not usually. The area we are working in has to be out of use while we’re there, so we book a time when it would be closed anyway.
Is there a survey before the work?
Yes, always. We diagnose before we treat: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
Managing agents and facilities teams in West Twyford
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
From a single site to a large estate, you get the same standard: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.

Signs you need ductwork cleaning in West Twyford
Many ducts do not have enough access panels. Sections between panels go uncleaned, sometimes since the system was installed, and grease there keeps thickening unseen.
These are the problems we see most often:
- A duct clean needed for an insurer
- Stale grease odours from the duct
- Grease pooling at the foot of the riser
- A duct nobody has opened in years
If you cook for passing trade around Stonebridge Park station, the extract can be cleaned between your last and first customer.
Before you book anyone
- Whether the whole system is included, or only the parts that are easy to reach
- When they can work, and whether that’s outside your opening hours
- Whether inaccessible sections are listed on the report
- Whether a survey comes first
What a clean will not put right
To be straight with you, some problems need a different fix:
- A damper stuck open in the duct
- Ductwork that was poorly designed
- Ductwork that’s corroded, split or holed (that needs a ductwork contractor)
Not sure which it is? You can phone us on 0345 646 2711 or drop us a line and we’ll tell you honestly.
Parts of the system we cover
- Horizontal duct runs
- Multi-storey ducts
- Vertical risers
- Attenuators
- Bends and junctions
- Access panels
What happens on the day
The visit has three parts: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with pictures. The middle part takes longest, and that takes a shift or more, depending on the length of the runs and the number of access points. In a London area like West Twyford, parking, loading and building access are planned before the day of the work.
- First the duct route is traced and every access point noted.
- Grease readings are taken at set points along the duct.
- Access panels are opened and heavy deposits scraped out by hand.
- The duct is degreased with the method that suits the grease, from degreasers to hot water or steam.
- Readings and pictures are repeated and any section we couldn’t reach is recorded.
Before we arrive
- Mention any parking or loading restrictions
- Tell us about site rules, permits or sign-in
- Dig out any earlier paperwork for the system
Getting a quote
There’s no standard price list, because no two systems are the same. We look at your system first, from photos or on a visit, then send a fixed quote. To get going, phone us on 0345 646 2711 or send us an email.

Grease, kitchens and West Twyford
There are about 255 cafés, restaurants and staff canteens and about 194 takeaways and sandwich shops within 1.5 miles or so of the middle of West Twyford, according to the Food Standards Agency’s register. Behind every canopy among them is a run of ductwork that collects grease out of sight. London Fire Brigade covers West Twyford. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel. In West Twyford, food businesses are inspected by environmental health officers from Ealing council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Our report lists what was cleaned and when, which is useful to have ready.
For schools such as West Twyford Primary School, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed. A hall kitchen that only cooks for events, whether near Church of St Mary or elsewhere in West Twyford, still needs its extract cleaned, just less often.

What affects the quote in West Twyford
Sites vary more than people expect. What affects the quote:
- Parking and loading at the site
- The times the site is available
- Whether we need access equipment or extra panels
- Site rules, permits and inductions
Putting the work off seldom saves money. Problems in a system tend to grow, which can make the next visit longer. If you are unsure, call 0345 646 2711 or use the quote form for straight advice and a fixed quote.
Helping us quote
Photos let us diagnose from a distance. The most useful are:
- Close-ups of filters, grilles, hatches or access panels
- Where the site is and what kind of site it is
- A few general shots of the system
- Your opening hours and when the area is out of use
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, you get a fixed price before any work starts.
Keeping the system healthy
Once we have finished, these simple steps help:
- File each certificate and photo report in the maintenance log
- Check readings when the menu changes
- Ask us about extra access panels where sections cannot be reached
- Keep access panels clear of stored items
Every panel we open is refitted when we finish, and the area around them is cleaned down. Waste grease and water are taken away.
Some signs mean the duct needs attention sooner: drips from the ductwork, stale smells or a noisy fan. Testing will show whether any section has reached 500 microns.
