About our ductwork cleaning in Blendon
We’ve been trading 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, and our certificates are issued through the BESCA Vent Hygiene Elite portal. We’re often asked to deal with an insurer asking for TR19 evidence and fat dripping from the ductwork, on horizontal duct runs, vertical risers and access panels.
In London, few kitchens can spare a day to close, so work in Blendon is normally booked for the night or the early hours. Parking, loading and access to the roof are agreed with the building before the night of the clean.
Duct Doctor has 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 are fully insured.

Grease, kitchens and Blendon
There are about 189 restaurants, cafés and works canteens and about 85 takeaways and sandwich shops across Blendon and its immediate surroundings (about a mile and a half), according to the Food Standards Agency’s register. Where they cook under a canopy, grease doesn’t stop at the filters: it settles along the duct and up the riser. Overnight is the normal time to clean a London kitchen extract, so trading is not affected. Blendon sits within the area of London Fire Brigade. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
Commuter trade near Albany Park station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands. Bursars and site managers at schools such as Blackfen School for Girls tend to book extract cleaning for when the kitchen is empty.

What your team can do, and what needs us
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
How it works
There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and the rest is down to us. Before we leave, the area is tidied and the paperwork follows. Security desks and permits-to-work are routine in London, so let us know what your building in Blendon needs from us.
- We map the duct route and check where the access panels are.
- We measure grease thickness at set points before cleaning.
- We open the panels and scrape out the heaviest grease.
- 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.
Preparing for the visit
- Tell us where we can park and unload
- Mention any locked doors, roof access or ceiling voids
- Tell us the best time to work, such as after service or at a weekend

Part by part
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.
Multi-storey and shared buildings
Ducts in taller or shared buildings often run past other occupiers. We plan access with you and the building manager, so the clean is done safely and quietly.
How we price ductwork cleaning
Some jobs are bigger than they look, and some smaller. The main factors:
- Whether several sites go on one quote
- The condition of the system
- How big the system is
- Any permits to work or inductions
A single site or a whole portfolio, the quote is built the same way: the work involved, the access and the timing. You will have a fixed price before any work starts.
Helping us quote
You don’t need the technical terms. It helps if you can send:
- The site address and the type of premises
- Your opening hours and when the area is out of use
- Detail shots of panels, filters and grilles
- Any symptoms, from odd noises to smells or leaks
If you need ductwork cleaning in Blendon, give us a ring on 0345 646 2711 or drop us a line. Tell us what kind of premises it is and when it’s open, and send pictures or your last report if you can. We usually send a fixed quote within one working day.
Questions from Blendon
Who inspects food businesses in Blendon?
The local authority for Blendon is Bexley council, and its environmental health team does the inspecting. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
How do you handle parking and loading in Blendon?
A loading bay, a visitor permit or off-street space near the site in Blendon makes the visit easier to plan. Where restrictions apply in the day, an evening or overnight visit normally gets round them.
What does TR19 mean?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It covers how systems are inspected, cleaned and checked, and it takes a risk-based approach.
Can you look after several sites?
Yes. Tell us the addresses and what each needs and we will quote them together.
What do you need from me for a quote?
Where the site is, what it is and when it’s open, along with a few pictures and any previous report.
When is the ductwork cleaned?
Out of hours, at a time that suits the kitchen. Long ducts can be split across visits, with the kitchen ready to cook each morning.
What if part of the duct can’t be reached?
Every reachable section is cleaned and the rest recorded. Fitting extra access panels is the usual answer, and we can do that for you.
What shows that the ducts need a clean?
We measure it. Using a Wet Film Thickness Test or Deposit Thickness Test, we check the grease at set points. BESA guidance says the mean shouldn’t exceed 200 microns, and 500 or more anywhere needs immediate spot cleaning.
Managing agents and facilities teams in Blendon
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Every building has its own written report, so records stay tidy.
Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.
Leave it or put it right?
Dealing with the ductwork in Blendon now beats dealing with it after a problem. The work takes a shift or more, depending on the length of the runs and the number of access points, done out of hours so the kitchen keeps cooking. Leaving it on a busy London site only adds to the work.
Every site is different, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.

Signs you need ductwork cleaning in Blendon
Air cools as it moves away from the canopy. As it cools, the grease it carries condenses onto the duct walls, which is why ducts go on gathering grease well beyond the filters.
Look out for any of the following:
- Ductwork that has never been cleaned
- A duct clean needed for an insurer
- Thick crusts of old grease along the duct
- A grease test showing the duct is overdue
Volunteers running a hall kitchen near St James the Great, or anywhere in Blendon, may not know when the extract was last cleaned, and a grease test settles it.
