About our ductwork cleaning in Barking
Nobody sees duct grease building, so nobody notices it until something goes wrong. A flare-up drawn up from the range can light it, and fire can then run along the ductwork to other parts of the building. Cleaning the duct takes that fuel away. If you’re dealing with grease seeping out of the duct seams and a duct nobody has opened in years, we can put it right, from vertical risers, horizontal duct runs and multi-storey ducts onwards.
London kitchens are often tucked into basements or the back of a building, and the duct may run up through several floors before it discharges at the roof. In Barking, as elsewhere in the capital, a long duct run means more access points to open and more grease to remove.
Duct Doctor has 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 are fully insured.

What staff can safely do
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that is where we come in.
Grease, kitchens and Barking
Food Standards Agency data counts about 155 restaurants, cafés and works canteens and about 106 takeaways in and around Barking, up to about a mile and a half out. The duct above a busy canopy coats itself in grease long before anyone sees it. Most London extract cleaning happens at night, after the last service. Fire safety in Barking falls to London Fire Brigade. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract.
Commuter trade near Barking station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands. Church and community hall kitchens, near St Patrick's Church or anywhere around Barking, are easy to forget, but their extracts collect grease like any other.

Why deal with it now?
A dirty duct is something insurers ask about. 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. In Barking, a planned overnight visit is much easier than closing unexpectedly.
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we will go through it with you.

Questions from Barking
Which environmental health team covers Barking?
That’s Barking and Dagenham council, whose environmental health officers carry out food hygiene inspections in Barking. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
Can you come to Barking after we close?
Yes, nights and weekends are routine for us. The site is handed back ready to open. Your opening times are the first thing we ask for.
What does ductwork cleaning cost?
We don’t publish prices, because the cost depends on the job: the size of the system, its condition, access and when we can work. You get a fixed price before work begins.
How often does extract ductwork need cleaning?
The duct is cleaned as part of the whole system, at intervals set by BESA guidance, from every 3 months for heavy use to every 12 months for light use. Readings tell you if it needs to be more often.
What about areas you can’t get to?
We never leave them off the paperwork. You’ll know exactly which parts weren’t reached and why, and we can quote to improve the access.
What do you do to protect the area?
Protection goes down first: floor sheeting and covers over nearby surfaces and equipment. We tidy up and take our waste away before we leave.
How do you clean inside the ductwork?
After a survey and grease readings, the duct is opened up through its access panels. We clean the runs and risers section by section, then the readings are repeated.
How much notice should we give?
That depends on the slot you want and the size of the job. Mention your preferred dates with your enquiry, and if it’s an emergency, call us any time.
Part by part
Vertical risers
Risers often pass through floors and walls, where fire dampers may be fitted. We test those as a separate job.
Multi-storey and shared buildings
A duct that climbs several floors may be cleaned over more than one visit. Visits are planned around the building’s hours, out of hours where possible.
What happens on the day
Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. All told, the work takes from a few hours to more than one visit, depending on duct length and access. Expect the work in Barking to happen after your last customer leaves, not during trading.
- First the duct route is traced and every access point noted.
- Set points along the runs are tested for grease.
- Through the access panels, thick grease is removed by hand first.
- Horizontal runs and risers are then degreased by the method that suits the deposit.
- Post-clean readings and photos go into the report, with any unreachable section listed.
Before we arrive
- Move anything stored near the system
- Let us know when the site is closed or quiet
- Allow time for equipment near the work to be turned off and cool down
Get a fixed quote
To get a fixed quote, ring 0345 646 2711 or send us an email with the site type, your trading hours and a short description of the system. A few photos and your last certificate or report help a lot. We usually come back within one working day.
Advice
Looking after it afterwards
To keep the system working properly between visits:
- Run the extract fan throughout service
- Keep your cleaning records together
- Tell us if grease leaks from the ductwork
- Keep access panels clear of stored items
When the duct is cleaned as part of a full TR19® Grease clean, a TR19 certificate is issued through the BESCA Vent Hygiene Elite portal. It records the date, the location and the technician.
Keep the fan on throughout service. Moving air carries vapour through rather than letting it settle, so switching off early adds to the build-up.
What we’re called out for in Barking
Grease settles fastest where the air slows down. Flat runs, bends, reducers and the base of risers are the usual hotspots, and those are the points we pay most attention to.
If you notice any of these, it’s worth a diagnosis:
- Thick crusts of old grease along the duct
- Stale grease odours from the duct
- A duct nobody has opened in years
- Thick deposits at the bottom of a vertical duct
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Barking Community Hospital is the nearest hospital to Barking, about within half a mile north.

When it’s something else
We will always give you a straight diagnosis, so here’s what this work can’t put right:
- Ductwork that’s corroded, split or holed (that needs a ductwork contractor)
- A failed fan motor at the end of the duct (a fan repair job)
- A damper stuck open in the duct
If you are not sure, just phone us on 0345 646 2711 or send us an email and we will give you a straight answer.
