Ductwork cleaning in Welling, done properly
Once air leaves the canopy, it travels through ductwork that most people never see. Grease settles along every metre of it, and that is where a kitchen fire can travel. Our ductwork cleaning reaches inside the runs and risers through access panels, to BESA TR19® Grease. Common call-outs are for a duct clean needed for an insurer and duct runs with no cleaning record, across vertical risers, multi-storey ducts and bends and junctions.
Across London, many commercial kitchens are squeezed into basements and narrow back-of-house spaces, with extract ducts that can climb several floors to discharge at roof level. For a kitchen in Welling, that typically means a longer system to clean and more access panels to plan around.
Nothing is signed off by word of mouth: a dated report with photos of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

Why act early in Welling
Under BESA guidance, the mean grease level should stay at or below 200 microns between cleans. Anywhere that reaches 500 microns or more needs immediate spot cleaning. Putting off the clean only pushes readings higher. In Welling, as across London, ductwork often passes through shared risers and other people’s space.
You will not find a price list here, because the cost depends on the site in front of us. For a fixed quote, call us on 0345 646 2711, or send details by email, and we will talk you through it.

Part by part
Attenuators and discharge
The discharge is where the duct ends and air leaves the building. Grease can collect there and stain the area around it, so it’s cleaned as far as safe access allows.
Vertical risers
A riser takes the duct up through one or more floors. Grease runs down the walls and gathers at the base, so the base is one of our test points.
What happens on the day
The first job on site is protection: sheeting goes over floors and surfaces close to the work. After that, the system is made safe and the work begins. The work on site takes a few hours for a short run, longer for long runs and tall risers, and the area is cleaned down before we leave. In a London area like Welling, parking, loading and building access are planned before the day of the work.
- First the duct route is traced and every access point noted.
- Grease readings are taken at set points along the duct.
- Access panels are opened and heavy deposits scraped out by hand.
- The duct is degreased with the method that suits the grease, from degreasers to hot water or steam.
- We test again, take photos and note any part that couldn’t be reached.
How to prepare
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Tell us where we can park and unload
- Agree a time when the area can be out of use

Advice
In-house cleaning or a specialist?
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
When it’s something else
A few issues sit outside what this work can do:
- Duct sealed behind fixed ceilings or walls
- Ductwork that is corroded, split or holed (that needs a ductwork contractor)
- A duct that is too small or badly routed for the kitchen (a design issue)
Not sure which it is? You can phone us on 0345 646 2711, or send details by email and we’ll tell you honestly.

Welling questions
Do you do school kitchen extract cleaning in Welling in the summer holidays?
Yes. The holidays are the usual time for school work. Around Welling, the Food Standards Agency lists about 34 schools and colleges with registered kitchens within a mile and a half or so. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Who inspects food businesses in Welling?
In Welling, it’s Bexley council that carries out food hygiene inspections. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
Can you look after several sites?
Yes. We work across South East England and London, so sites at different addresses can be planned together as one programme. Every site has its own report.
Can you set up regular visits?
Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. The report from each visit recommends the next date.
Do you cover Welling?
Yes. We work in Welling and the rest of Greater London, as part of our work across South East England and London. For a fixed quote, phone us on 0345 646 2711 or drop us a line.
How do you protect the area?
Protection goes down first: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.
Which accreditations do you hold?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We’ve been trading since 2009 and we’re fully insured.
How much does ductwork cleaning cost in Welling?
It depends on the site, so we quote each one individually. For a quote, call us on 0345 646 2711 or email us and tell us about the site and its opening hours.
Managing agents and facilities teams in Welling
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.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
Welling kitchens: local notes
There are about 139 restaurants, cafés and canteens and about 93 takeaways and sandwich shops in Welling and the streets around it, up to about 1.5 miles out, according to the Food Standards Agency’s register. Each kitchen that cooks under a canopy sends grease-laden air into a duct, where it cools and settles. Welling is covered by London Fire Brigade. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. London jobs usually start after the last service, with loading and roof access agreed with the building first.
If you run a café or takeaway near Welling station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits. Volunteers running a hall kitchen near St John's Church, or anywhere in Welling, may not know when the extract was last cleaned, and a grease test settles it. School kitchens, at schools like Danson Primary School for example, are usually cleaned in the holidays so no lunches are lost.

Keeping the system healthy
A little care between visits keeps the system in better shape. We recommend:
- Flag drips from the duct right away
- Do not switch the extract off early
- Keep your cleaning records together
- Make sure filters are seated properly
Grease readings are taken again at the same set points, giving you before and after readings. Photos of each section go alongside them.
Extra access panels mean more of the duct gets cleaned each time. It does not stop grease forming, but it stops it building unseen.
