About our ductwork cleaning in Wanstead
Between the canopy and the fan runs the ductwork, hidden above ceilings and inside walls. Every horizontal run and vertical riser collects grease along the way, and that’s where a kitchen fire can travel. Our ductwork cleaning reaches inside the runs and risers through access panels, to BESA TR19® Grease. The work covers access panels, horizontal duct runs and bends and junctions, and people most often call us about fat dripping from the ductwork and sections of duct with no access panels.
In London, few kitchens can spare a day to close, so work in Wanstead 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. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.

Landlords, agents and facilities managers
For anyone managing more than one site, we can schedule visits across all of them on one quote. Every building has its own written report, so records stay tidy.
Keeping records across a portfolio is half the battle. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.
Wanstead: your questions answered
Who would carry out a food hygiene inspection at a kitchen in Wanstead?
Kitchens in Wanstead are inspected by Redbridge council’s environmental health officers. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
How do you handle parking and loading in Wanstead?
London parking can be tight, so details of loading bays and permits help. Working overnight, as we often do in London, normally makes it simpler.
Do you survey before quoting?
Yes, every time. We diagnose before we treat: the survey shows what needs doing and what access we need and the fixed quote is built on it.
Are you insured?
Yes. We are fully insured, and the details are available on request.
What types of premises do you cover?
Any site with a kitchen or a ventilation system to look after, from a small pub to a hospital. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
Can you come out in an emergency?
Yes, day and night, every day of the year. Office hours are Monday to Friday, 8am to 6pm, and the emergency line covers the rest.
How do you know if the ductwork needs cleaning?
A grease thickness test gives the answer. Readings are taken by Wet Film Thickness Test (WFTT) or Deposit Thickness Test (DTT). A mean above 200 microns, or 500 microns at any point, means it’s due.
How is kitchen extract ductwork cleaned?
We get into the duct through its access panels. Thick deposits are removed by hand before degreasing, such as degreasers, hot water or steam.
Wanstead kitchens: local notes
The FSA’s food hygiene register includes about 33 pubs and bars and about 6 hotels, B&Bs and guest houses in and around Wanstead, up to about a mile and a half out. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. In London, kitchens are usually cleaned overnight, when the kitchen is closed and loading is easier. It’s Redbridge council that sends environmental health officers to food businesses in Wanstead. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Keeping each certificate and photo report on file helps show the extract is looked after.
If you look after a school kitchen, at a school such as Wanstead Church School or anywhere near Wanstead, the holidays are the usual time for a TR19® clean. Healthcare kitchens, like those at hospitals such as Wanstead Hospital (about 0.5 miles north), often cook for long hours, which puts them in BESA’s heavier-use bands.

When something else is needed
To be straight with you, there are a few things this work will not fix:
- Parts of the duct with no way in
- Undersized or badly laid-out ducts
- A worn-out fan that needs replacing
If in doubt, give us a ring on 0345 646 2711 or send us an email and we will say what we think before you book.
Parts of the system we cover
- Access panels
- Bends and junctions
- Vertical risers
- Attenuators
- Multi-storey ducts
- Horizontal duct runs
Keeping the system healthy
Looking after the system between visits is straightforward, and it helps at the next visit:
- Have the grease measured if cooking hours go up
- Keep to the interval on the report
- Make sure filters are seated properly
- Do not switch the extract off early
After the clean, the same points are tested again, so the report shows the before and after figures. Photos of each section go alongside them.
Keep the fan on throughout service. When the air stops, grease settles in the duct, so switching off early adds to the build-up.

Common problems we fix in Wanstead
Grease filters that do not seal let fat straight through. More grease reaches the ductwork than it should and it fills faster.
Keep an eye out for these warning signs:
- Sections of duct with no access panels
- Grease leaking from duct joints
- Years of grease along the duct floor
- A duct nobody has opened in years
Volunteers running a hall kitchen near Wanstead United Reformed Church, or anywhere in Wanstead, may not know when the extract was last cleaned, and a grease test settles it.

- What insurance they carry
What affects the cost of ductwork cleaning
We do not publish a price list, because sites vary so much. The quote depends on:
- When the work can happen, such as evenings, overnight or weekends
- A single visit or a regular plan
- The condition of the system
- How many systems or sites are involved
What you pay reflects the actual work. That’s why we survey first, from pictures or on site, and the price is agreed before any work starts.
Helping us quote
Before you ask for a quote, gather:
- Problems your staff have spotted
- Close-ups of filters, grilles, hatches or access panels
- The times we could work without disrupting the site
- The paperwork from the last visit, if you have it
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
What the work involves, part by part
Horizontal duct runs
A long flat run cannot be cleaned from one end. Where the gaps between panels are too long, we record what couldn’t be reached and can fit extra panels.
Access panels
Extra panels can be installed where there are gaps, making future cleans more complete. The survey shows where they’re needed.
What we do, step by step
Before we leave, we walk the area with whoever is on site. Anything we couldn’t reach or that needs attention is pointed out there and then, and the same goes into the written report. The visit takes from a few hours to more than one visit, depending on duct length and access. In Wanstead, as across London, we normally work overnight or at weekends and hand the site back ready to open.
- First the duct route is traced and every access point noted.
- Grease readings are taken at set points along the duct.
- Through the access panels, thick grease is removed by hand first.
- Next the ducts and risers are degreased, using whatever suits the deposit.
- Post-clean readings and pictures go into the report, with any unreachable section listed.
Getting ready for the visit
- Clear loose items from the work area
- Allow time for equipment near the work to be turned off and cool down
- Let us know how we reach the system, including roofs, risers and plant rooms
