Ductwork cleaning in Thamesmead, Greater London
Cleaning of kitchen extract ductwork, horizontal runs and vertical risers through access panels for businesses, landlords and public buildings in Thamesmead. BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease.
- An insurer asking for TR19 evidence
- Smells of old cooking grease from the ductwork
- High readings at a recent grease test
What happens on the day
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool first, and the area around the work is covered and protected. The work itself takes a shift or more, depending on the length of the runs and the number of access points. Night and weekend working is normal for us in London, and a site in Thamesmead is no exception.
- We trace the duct and find every way in.
- We take grease readings along the route.
- Once the kitchen has closed, we protect the area and open the panels.
- Thick grease is scraped out, then the runs and risers are degreased.
- We close up, re-test, photograph and record anything out of reach.
Preparing for the visit
- Move anything stored near the system
- Mention any locked doors, roof access or ceiling voids
- Tell us where we can park and unload

Advice
About our ductwork cleaning in Thamesmead
In doctor’s terms, the ductwork is the system’s arteries: find the blockages, clear them, then check the flow is right. Grease readings before and after give you the evidence, alongside before and after pictures. Typical jobs include readings above 200 microns from a grease thickness test and duct runs that can’t be reached, across multi-storey ducts, bends and junctions and horizontal duct runs.
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. In Thamesmead, as elsewhere in the capital, a long duct run means more access points to open and more grease to remove.
The paperwork matters as much as the work. You get a written report with photos after every visit, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

How the job changes from site to site
Vertical risers
In taller buildings, a riser may pass through several floors and fire compartments, so fire dampers may be fitted where it crosses them. We test those as a separate job.
Attenuators and discharge
The discharge is where the duct ends and air leaves the building. It can gather grease and mark the wall or roof around it, so it’s cleaned as far as safe access allows.
Grease, kitchens and Thamesmead
The FSA’s data shows about 7 pubs, bars and clubs registered within roughly a mile and a half of the centre of Thamesmead. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. Kitchens in Thamesmead get their food hygiene inspections from Greenwich council. 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. In London, kitchens are typically cleaned overnight, when the kitchen is closed and loading is easier.
If you run a church or community hall kitchen, near St Paul or elsewhere in Thamesmead, its extract still collects grease from every lunch and event. Eastbury Manor House, about 2.4 miles north-west, is one of the historic houses near Thamesmead; if you run event catering at a venue like that, cleans can be booked between functions.
Thamesmead is about 2 miles north-east of Plumstead, in Greater London. Wherever you are in the SE28 postcode area, we can carry out ductwork cleaning at your premises. Thamesmead is one of 764 places in Greater London where we work for ductwork cleaning. For sites nearby, see our London page (10 miles or so).
Ductwork cleaning in SE28, SE2 and DA18 is surveyed, quoted and booked the same way as anywhere else. Streets in the area include Attlee Road, Aisher Road and Carlyle Road, all of which we cover for ductwork cleaning. We also cover Crossness (1 mile south-east), Dagenham Dock (1 mile north-east), Barking Riverside (1 mile north-west), Thames View Estate (2 miles north-west) and Hornchurch Marshes (2 miles north-east). Larger places within reach include London (10 miles west), City of Westminster (12 miles west), Marylebone (12 miles west), Kensington (14 miles west), St Pancras (11 miles west) and Shoreditch (9 miles west).
Landmarks near Thamesmead
Locally, jobs take us to businesses close to Harris Garrard Academy and Abbey Wood Park. The nearest railway station is Abbey Wood station, roughly 1 mile south of the centre. Other landmarks nearby include Greenwich Borough Museum (1.7 miles south-west) and Gallions Reach Shopping Park (2 miles west). For a walk, there’s Crossness Nature Reserve.
What happens if it’s left?
A dirty duct is something insurers ask about. Many policies require TR19 cleaning, and a claim may be refused or reduced without evidence. A certificate that covers the ductwork is what they want to see. Every month a London system goes without attention adds to what has to be done later.
Every site is different, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all make a difference.

Common questions in Thamesmead
How do you handle parking and loading in Thamesmead?
A loading bay, a visitor permit or off-street space near the site in Thamesmead makes the visit easier to plan. If the building has a loading slot system, we’ll book into it.
Can you clean school kitchen extracts in Thamesmead during the holidays?
Yes, out-of-term visits are normal for schools. With about 29 schools and colleges on the FSA’s register within roughly a mile and a half of Thamesmead, it pays to plan holiday dates ahead. Tell us your holiday dates and we will book the visit for when the site is empty.
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 for anything urgent, ring our 24/7 emergency line.
What happens if there aren’t enough access panels?
Every reachable section is cleaned and the rest recorded. Fitting extra access panels is the usual answer, and we can do that for you.
How is kitchen extract ductwork cleaned?
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.
How long does it take to clean extract ducts?
It takes a few hours for a short run, longer for long runs and tall risers. We will confirm the time when we quote.
Where does the waste go?
We contain it and take it with us. Grease, debris and waste water are collected as the work goes on, so it doesn’t spread.
Do you offer emergency callouts?
Yes, 24/7. Our office is open from 8am to 6pm on weekdays, and the emergency line covers the rest.
Keeping the system healthy
A little care between visits keeps the system in better shape. We recommend:
- Don’t block access panels with shelving or stock
- Consider fitting panels where the report shows gaps
- Flag drips from the duct right away
- Do not switch the extract off early
Any section of duct we couldn’t reach is listed on the report, with the reason. You can then decide whether to have access panels fitted.
Extra access panels mean more of the duct gets cleaned each time. It doesn’t stop grease forming, but it stops it building unseen.
Landlords, agents and facilities managers
Records are where multi-site compliance often slips. Every visit ends with a dated report and photos, so you can show an insurer or inspector what was done at each site.
We also work for facilities teams across offices, schools and healthcare across Greater London. Work can be phased by floor, building or site to keep disruption down.
What we are called out for in Thamesmead
A greasy duct is a fire path, in Thamesmead as anywhere. Once it lights, fire can spread along the duct and into other areas, which is why the responsible person needs it under control.
Common reasons sites call us include:
- Grease pooling at the foot of the riser
- Years of grease along the duct floor
- Stale grease odours from the duct
- Duct runs that can’t be reached
If you run catering at a healthcare site, such as a hospital like Erith and District Hospital about 2.6 miles south-east, the extract may need cleaning more often than a part-time kitchen.
What your quote should include
- What’s included in the scope, part by part

- How areas they can’t reach will be recorded
Fixed quotes for ductwork cleaning in Thamesmead
The price is fixed before any work begins. It’s based on:
- Whether several sites go on one quote
- Site requirements such as sign-in and permits
- The scale of the work
- One-off work versus a regular cycle
A single site or a whole portfolio, we price it on the same basis: the work involved, the access and the timing. You will have a fixed price before any work starts.
What to send for a quote
The more you tell us, the more accurate the quote. With your enquiry, please include:
- Problems your staff have spotted
- Close-ups of filters, grilles, hatches or access panels
- Your opening hours and when the area is out of use
- Any previous report or certificate
The quickest way to a quote is to send pictures: 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 many jobs can be priced from that alone.
