Ductwork cleaning in New Malden, done properly
Duct Doctor has cleaned kitchen extract ductwork since 2009, working across London and the South East. As a BESCA Vent Hygiene Elite member, our duct cleaning is done to BESA TR19® Grease, and our certificates are issued through the BESCA Vent Hygiene Elite portal. Typical jobs include grease pooling at the foot of the riser and sections of duct with no access panels, on bends and junctions, attenuators and access panels.
London kitchens are often tucked into basements or the back of a building, with extract ducts that can climb several floors to discharge at roof level. In New Malden, as elsewhere in the capital, a long duct run means more access points to open and more grease to remove.
For insurers and inspectors, the record counts. That is why every job is written up in a report with photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

What the work involves, part by part
Access panels
We can fit new access panels where the duct needs them, making future cleans more complete. The survey shows where they’re needed.
Bends and transitions
A bend can hold far more grease than a straight run of the same length. We clean it back by hand and with degreaser, and readings are taken there before and after.
For landlords and multi-site operators
We regularly work with managing agents. Tell us the site, the work and the access arrangements, and we will send a fixed quote.
Multi-site operators often want one contractor and one number. We cover South East England and London, so visits at different addresses can be planned together and kept to a regular schedule.
When to call us in New Malden
A duct with too few access doors cannot be fully cleaned. Sections between panels go uncleaned, sometimes since the system was installed, and the grease there keeps building out of sight.
Most sites get in touch when they notice one of these:
- Proof of duct cleaning for the insurer
- Smells of old cooking grease from the ductwork
- Heavy grease at the base of a riser
- A duct nobody has opened in years
Healthcare kitchens, like those at hospitals such as Kingston Hospital (about 1.2 miles north-west), often cook for long hours, which puts them in BESA’s heavier-use bands.
Questions to ask before booking
- How VAT is shown on the quote
- Whether the quote is based on a survey or photos
- If the quote is a fixed price or an estimate
- Whether they’re fully insured
Ductwork cleaning in New Malden: the local picture
According to Food Standards Agency records, there are about 26 pubs and bars in New Malden and the streets around it, up to about 1.5 miles out. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. New Malden is covered by London Fire Brigade. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises. Night work suits London kitchens, and roads and loading bays tend to be quieter too.
Where a hall near New Malden Baptist Church, or anywhere in New Malden, hosts lunch clubs or events, its extract gathers grease just as a café’s does. Commuter trade near New Malden station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands.

Landmarks near New Malden
Around New Malden, our work takes us to kitchens and buildings near Beverley Park, The Glasshouse pub and Holy Cross School. There’s a railway station in New Malden itself: New Malden station.

What staff can safely do
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.
Your questions about ductwork cleaning in New Malden
Who inspects food businesses in New Malden?
That’s Kingston-Upon-Thames council, whose environmental health officers carry out food hygiene inspections in New Malden. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
Is parking a problem for work in New Malden?
A loading bay, a visitor permit or off-street space near the site in New Malden makes the visit easier to plan. Night visits tend to make loading easier on London streets.
How can I tell if my extract ducts are dirty?
Signs include grease dripping from joints, smells and a fan working harder, but the only sure way is to measure. A WFTT or DTT reading gives a clear answer.
What if part of the duct cannot be reached?
Ductwork needs access to be cleaned. We record those sections on the report and can fit access panels.
How do you keep the site clean during the work?
Floors and surfaces near the work are sheeted before any work starts, and anything we remove is contained. At the end, the area is cleaned down.
Which sectors do you work in?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, as well as food production and leisure sites.
Are you fully insured?
Yes, fully. CHAS and SafeContractor accreditation sit alongside it for clients who vet their contractors.
Do you look at the system first?
Yes, every time. We diagnose before we treat: the survey tells us what the system needs and how to reach it, and the quote is based on that.
When it’s something else
Ductwork cleaning can’t fix everything, and we’d rather say so up front. It does not solve:
- Ductwork that’s corroded, split or holed (that needs a ductwork contractor)
- Fire dampers that don’t close (they need testing and remedials)
- Ductwork that was poorly designed
If you are not sure, just give us a ring on 0345 646 2711, or send details by email and we’ll give you a straight answer before booking.

How we price ductwork cleaning
Every site gets its own quote. These are the things that affect it:
- The size of the system
- Where the site is and how we reach it
- The times the site is available
- Any permits to work or inductions
When the work has to happen, how we reach it and how big the site is can all change the price. Each of those is built into the quote and give you a fixed price before any work starts.
Helping us quote
There’s no need for technical detail. It helps if you can send:
- Detail shots of panels, filters and grilles
- Problems your staff have spotted
- The site address and the type of premises
- The paperwork from the last visit, if you have it
We don’t publish a price list, because every site is different. Instead, we look at your site first, from pictures or a survey, then send a fixed quote. To start, give us a ring on 0345 646 2711 or drop us a line.
