Ductwork cleaning in Dunkirk, done properly
Duct Doctor has cleaned kitchen extract ductwork since 2009, working across London and the South East. As a BESCA Vent Hygiene Elite member, our duct cleaning is done to BESA TR19® Grease, with each certificate issued through the BESCA portal. The work covers vertical risers, multi-storey ducts and bends and junctions, and common reasons people get in touch are an insurer asking for TR19 evidence and duct runs that can’t be reached.
Work in a small place like Dunkirk starts with a call to agree access and timings, and the clean covers the whole system, as it would anywhere: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.
We’ve been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

What ductwork cleaning can’t fix
To be straight with you, there are a few things this work won’t fix:
- A failed fan motor at the end of the duct (a fan repair job)
- Fire dampers that do not close (they need testing and remedials)
- Parts of the duct with no way in
If you’re not sure, just call us on 0345 646 2711, or send details by email and we’ll give you a straight answer.

What we do, step by step
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, while signing off means the written report and pictures. Most of the time goes on the work itself, which takes anything from a few hours to several visits, depending on the length of duct. Photos of the system and how to reach it help us plan a visit to Dunkirk.
- 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
- Move anything stored near the system
- Dig out any earlier paperwork for the system
- Agree a time when the area can be out of use

Dunkirk: your questions answered
Can you come to Dunkirk after we close?
Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in Dunkirk needn’t be disturbed. Your opening times are the first thing we ask for.
Which council inspects kitchens in Dunkirk?
Kitchens in Dunkirk are inspected by Swale council’s environmental health officers. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
What’s involved in cleaning extract ducts?
After a survey and grease readings, the duct is opened up through its access panels. Each run and riser is scraped and degreased, then the readings are repeated.
Can you look after several sites?
Yes. You deal with one contact for every site in our area, with visits on a regular schedule.
Can you fit access panels in our ductwork?
Yes, we install duct access panels. Panels go where they give the best access to sections that couldn’t be reached, and we will recommend where.
How do you keep the site clean during the work?
We start with protection: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.
How can I tell if my extract ducts are dirty?
We measure it. Using a Wet Film Thickness Test or Deposit Thickness Test, we check the grease at set points. A mean above 200 microns, or 500 microns at any point, means it’s due.
Who has the legal duty for fire safety?
Under the Regulatory Reform (Fire Safety) Order 2005, it’s the responsible person: often the employer, owner or occupier. Landlords, facilities managers and managing agents can also hold responsibility.
What we’re called out for in Dunkirk
The further the air travels from the cooking, the cooler it gets. Cooling air drops its grease onto the inside of the duct, which is why ducts go on gathering grease well beyond the filters.
Most sites get in touch after spotting something like this:
- Duct runs that cannot be reached
- A grease test showing the duct is overdue
- Smells of old cooking grease from the ductwork
- Grease pooling at the foot of the riser
A hospital like Eastbridge Hospital of St Thomas the Martyr, about 4.4 miles east, is the kind of site where a kitchen may cook for patients, staff and visitors all day.

Why it’s worth doing now in Dunkirk
Insurers know the risk of a greasy duct. Many policies require TR19 cleaning, and a claim may be refused or reduced without evidence. Your certificate and photo report show the ducts were cleaned. Our emergency line runs 24/7, but a planned visit to Dunkirk is calmer for everyone.
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 are unsure, call 0345 646 2711 or drop us a line for straight advice and a fixed quote.

Grease, kitchens and Dunkirk
Look up Dunkirk on the FSA’s food hygiene register and you will find about 5 restaurants, cafés and works canteens in and around Dunkirk, up to about a mile and a half out. Behind every canopy among them is a run of ductwork that collects grease out of sight. Environmental health officers from Swale council inspect food businesses in Dunkirk. Extraction counts as kitchen equipment, so its condition can come up on the day. A dated certificate in the maintenance file answers the question before it’s asked. Kent Fire and Rescue Service covers Dunkirk. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.
If you run a church or community hall kitchen, near Christ Church or elsewhere in Dunkirk, its extract still collects grease from every lunch and event.

What your team can do, and what needs us
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
Part by part
Multi-storey and shared buildings
In a building with several floors, the duct may pass other tenants’ spaces. Access is planned with the building’s managers, so the clean is done safely and quietly.
Horizontal duct runs
Flat runs of duct link the canopy to the riser or the outside wall. Grease drops out of the slowing air along them, and we clean them section by section through access panels.
Between visits
Think of this as the after-treatment advice, in brief:
- Book the next clean before the recommended date
- Report any grease dripping from duct joints
- Never cook with a filter missing
- Leave a way through to the access panels
Any section of duct we couldn’t reach is listed on the report and why. You can then decide whether to have access panels fitted.
Keep the fan on throughout service. When the air stops, grease settles in the duct, so switching off early adds to the build-up.
