Southall ductwork cleaning
Ductwork cleaning for commercial sites in Southall and across Greater London. BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease.

- Grease seeping out of the duct seams
- Duct runs with no cleaning record
Why it’s worth doing now in Southall
There’s no law that names TR19. Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, including the grease inside the extract ductwork. In a London building, a problem in a duct, damper or fan rarely stays in one unit.
A single site or a whole portfolio, the quote is built the same way: what needs doing, how we get to it and when. The price is fixed before work begins.

How we handle ductwork cleaning in Southall
Duct Doctor has cleaned kitchen extract ductwork since 2009, working across London and the South East. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and our certificates are issued through the BESCA Vent Hygiene Elite portal. The work covers vertical risers, multi-storey ducts and access panels, and people most often call us about heavy grease at the base of a riser and duct runs that can’t be reached.
In a London area like Southall, a kitchen extract often passes through shared space on its way out: a riser, a service void, the floors above. Grease in a duct like that is a fire risk to the whole building, not just the kitchen, which is why keeping it clean to TR19® matters.
Each visit ends with a written report and photos, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Ductwork cleaning around Southall
The FSA’s data shows about 22 pubs, bars and clubs and about 4 hotels and B&Bs registered in Southall 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. Southall is covered by London Fire Brigade. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel. Overnight is the normal time to clean a London kitchen extract, so trading is not affected.
If you run catering at a healthcare site, such as a hospital like St Bernard's Hospital about 1.2 miles east, the extract may need cleaning more often than a part-time kitchen. A hall kitchen that only cooks for events, whether near Saint John or elsewhere in Southall, still needs its extract cleaned, just less often.

FAQs for Southall

Do you do school kitchen extract cleaning in Southall in the summer holidays?
Yes. The holidays are the usual time for school work. With about 37 schools and colleges on the FSA’s register within roughly a mile and a half of Southall, it pays to plan holiday dates ahead. You can call 0345 646 2711, or send details by email with the dates the site is empty.
Is Southall in your area?
Yes. Southall is part of the area we cover, as part of our area across London and the South East.
Which kinds of sites do you work on?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, plus food production and leisure sites.
Do you survey before quoting?
Yes. We always survey first, from your photos and details, or with a visit where necessary. A fixed quote follows.
How long does it take to clean extract ducts?
Duct length, access and grease levels all affect it. As a guide, it takes from a few hours to more than one visit, depending on duct length and access.
How much does ductwork cleaning cost?
Every site is different, so each gets its own fixed quote. For a quote, call us on 0345 646 2711 or email us and tell us about the site and its opening hours.
How can I tell if my extract ducts are dirty?
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.
Common problems we fix in Southall
Grease filters that don’t seal let fat straight through. More grease reaches the ductwork than it should, and build-up speeds up.
Any of these means the system needs a check-up:
- A duct nobody has opened in years
- Proof of duct cleaning for the insurer
- A rancid smell from the extract duct
- Years of grease along the duct floor
School kitchens, at schools like Hambrough Primary School for example, are typically cleaned in the holidays so no lunches are lost.

Keeping the system healthy
How long the results last depends on use and care. Here’s what we suggest:
- Ask for a grease thickness test if the kitchen gets busier
- Keep grease filters clean and fitted whenever you cook
- Diarise the next duct clean
- Flag drips from the duct straight away
Keep the certificate and report with the fire risk assessment. It’s the evidence an insurer or inspector may ask for, and the pictures make the duct’s condition easy to see.
Some signs mean the duct needs attention sooner: grease leaking from duct joints, smells, or a fan that sounds rough. Testing will show whether any section has reached 500 microns.
When something else is needed
Ductwork cleaning cannot fix everything, and we’d rather say so up front. It won’t put right:
- Ductwork that’s corroded, split or holed (that needs a ductwork contractor)
- Parts of the duct with no way in
- Fire dampers that do not close (they need testing and remedials)
Not sure which it is? You can call 0345 646 2711 or send us an email and we will tell you honestly before you book.
What the work covers
- Vertical risers
- Bends and junctions
- Multi-storey ducts
- Access panels
- Horizontal duct runs
- Attenuators
How it works
When we arrive, we check the system against the survey or the photos you sent. Anything unexpected is raised with you before we go further. From there, it takes a few hours for a short run, longer for long runs and tall risers. A name and number for whoever controls access to the building in Southall saves time on the night.
- We start by working out how the duct runs and where it can be opened.
- We measure grease thickness at set points before cleaning.
- We open the panels and scrape out the heaviest grease.
- Next the ducts and risers are degreased, using whatever suits the deposit.
- We test again, take pictures and note any part that couldn’t be reached.
Getting ready for the visit
- Tell us where we can park and unload
- Have your last certificate or report to hand
- Clear the space around the work

For landlords and multi-site operators
We also work for facilities teams across offices, schools and healthcare in Southall and across Greater London. Larger estates can be phased building by building around the people who use them.
From a single site to a large estate, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with pictures.
Staff cleaning versus specialist work
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.
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 grease that has passed the filters is out of reach. That part needs specialist access and equipment.
