Ductwork cleaning in North Cray
In doctor’s terms, the ductwork is the system’s arteries: diagnose where grease has built up, clear it and confirm the result. Grease readings before and after give you the evidence, alongside before and after pictures. The work covers horizontal duct runs, multi-storey ducts and bends and junctions, and the jobs we see most are a rancid smell from the extract duct and grease leaking from duct joints.
Across London, many commercial kitchens are squeezed into basements and narrow back-of-house spaces, and the duct may run up through several floors before it discharges at the roof. For a kitchen in North Cray, that typically means a longer system to clean and more access panels to plan around.
For insurers and inspectors, the record counts. That’s why every job is written up in a report with photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Staff cleaning versus specialist work
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Looking after it afterwards
Simple habits between visits make a real difference. We recommend:
- Keep access panels clear of stored items
- Tell us if grease leaks from the ductwork
- Run the extract fan throughout service
- Check readings when the menu changes
Every panel we open is refitted when we finish, and the area around them is cleaned down. Waste grease and water are taken away.
Keep to the cleaning interval on the report. A change in cooking hours may change the interval under BESA guidance, and grease thickness testing will show it.
What affects the quote in North Cray
The diagnosis comes before the price. We look at:
- The scale of the work
- Working hours and out-of-hours timing
- How many systems or sites are involved
- Any permits to work or inductions
You will not find a price list here, because each job is priced on what it involves. For a fixed quote, phone us on 0345 646 2711 or send us an email, and we will explain what it covers.
Asking for a quote
When you contact us, these details help:
- The paperwork from the last visit, if you have it
- The roof, plant room or outside wall the system runs to
- The site address and the type of premises
- Any access panels or hatches you can see
Quoting starts with a diagnosis, from your pictures and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work, before any work starts.
What the work involves, part by part
Bends and transitions
The join where the canopy meets the duct is a common hotspot. We reach it from the plenum side where possible.
Access panels
Extra panels can be installed where there are gaps, so the next clean reaches more of the system. The survey shows where they’re needed.
The process
There’s very little for your team to do on the day. A contact on site lets us in at the agreed time and points us to the system, and we take it from there. Afterwards, the area is left tidy and the written report follows. Getting kit into a London building takes planning, so let us know where we can load and park in North Cray.
- The duct route is surveyed and every access point found.
- 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.
- Panels are closed, readings and pictures repeated, and unreachable sections recorded.
Getting ready for the visit
- Let us know how we reach the system, including roofs, risers and plant rooms
- Let us know about parking and loading
- Make sure equipment near the work can be switched off and left to cool

Do you need ductwork cleaning in North Cray?
Air cools as it moves away from the canopy. Cooling air drops its grease onto the inside of the duct, which is why ducts go on gathering grease well beyond the filters.
If you notice any of these, it’s worth a diagnosis:
- An insurer asking for TR19 evidence
- Heavy grease at the base of a riser
- Thick crusts of old grease along the duct
- Grease seeping out of the duct seams
Where a hall near Parish Church of St James, or anywhere in North Cray, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

Common questions in North Cray
Can the work in North Cray be done at night or at weekends?
Yes, we can come after you close and finish before you open. It means the site in North Cray keeps running as normal. When you call 0345 646 2711 or use the quote form, mention when the site is quiet.
Can school kitchens in North Cray be cleaned in the holidays?
Yes. The holidays are the usual time for school work. With about 16 schools and colleges on the FSA’s register within roughly a mile and a half of North Cray, it pays to plan holiday dates ahead. Tell us your holiday dates and we will book the visit for when the site is empty.
What shows that the ducts need a clean?
We measure it. Readings are taken by Wet Film Thickness Test (WFTT) or Deposit Thickness Test (DTT). BESA guidance says the mean shouldn’t exceed 200 microns, and 500 or more anywhere needs immediate spot cleaning.
What’s involved in cleaning extract ducts?
Each section is cleaned through its own panel. Heavy grease comes out by hand, and what’s left is degreased, with readings taken before and after.
What is TR19?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t law, but it’s the benchmark.
How much notice do you need?
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.
Which kinds of sites do you work on?
Commercial premises of every kind: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. We fit the work around how the site operates.
Do you work in North Cray?
Yes. Our technicians work in North Cray, within the South East and London area we cover.
What ductwork cleaning looks like in North Cray
According to Food Standards Agency records, there are about 37 bars, pubs and nightclubs and about 3 hotels, B&Bs and guest houses within 1.5 miles or so of the middle of North Cray. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. The fire and rescue service for North Cray is London Fire Brigade. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. In North Cray, food businesses are inspected by environmental health officers from Bexley council. Extraction counts as kitchen equipment, so its condition can come up on the day. Before-and-after pictures from each clean are a simple way to show the extract is in hand.
If you run a café or takeaway near Albany Park station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits. A hospital like Bexley Hospital, about 1.8 miles north, is the kind of site where a kitchen may cook for patients, staff and visitors all day.
