Common problems we fix in Lisson Grove
A greasy duct is a fire path, in Lisson Grove as anywhere. Burning grease can carry fire through the ductwork to other rooms or floors, which is why the responsible person needs it under control.
These are the problems we see most often:
- Ductwork that has never been cleaned
- High readings at a recent grease test
- Grease seeping out of the duct seams
- A rancid smell from the extract duct
Where a hall near St Paul's Community Church, or anywhere in Lisson Grove, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

Ductwork cleaning for kitchens and businesses in Lisson Grove
Not every duct has enough access panels. TR19 calls for any section we couldn’t reach to be recorded, and we can fit new access panels so it’s cleaned next time. It’s better to know than to assume. The work covers multi-storey ducts, horizontal duct runs and bends and junctions, and people most often call us about grease pooling at the foot of the riser and fat dripping from the ductwork.
Kitchens in Lisson Grove, like many across London, can share a building with flats or offices, with the duct running up through shared risers. A duct fire there can reach parts of the building far from the range, so a regular TR19® clean protects everyone in it.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.

The process
The first job on site is protection: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. It takes anything from a few hours to several visits, depending on the length of duct, and we clear up before we go. A name and number for whoever controls access to the building in Lisson Grove saves time on the night.
- Diagnosis: a survey of the duct’s route, size and access.
- A fixed quote follows, based on what we found.
- We clean section by section, working from panel to panel.
- We take extra care at bends and at the foot of risers.
- The duct is signed off with readings, photos and a next clean date.
How to prepare
- Mention any locked doors, roof access or ceiling voids
- Let us know about parking and loading
- Plan for cooking equipment or plant to be off before we arrive
Ask for a quote
Some systems can be priced from pictures; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before any work starts.
Related advice
What the work involves, part by part
Access panels
We can fit new access panels where the duct needs them, so the next clean reaches more of the system. We’ll recommend where they should go.
Bends and transitions
Bends, elbows and changes of size are where grease collects most. Slowing air leaves grease behind, so these points get extra attention.
Keeping the system healthy
Think of this as the after-treatment advice, in brief:
- Check readings when the menu changes
- Report any grease dripping from duct joints
- Ask us about extra access panels where sections cannot be reached
- Don’t block access panels with shelving or stock
After the clean, the same points are tested again, giving you before and after readings. Before and after pictures sit next to the numbers.
Some signs mean the duct needs attention sooner: drips from the ductwork, stale smells or a noisy fan. Testing will show whether any section has reached 500 microns.
Managing agents and facilities teams in Lisson Grove
We also work for facilities teams across offices, schools and healthcare in Lisson Grove and across Greater London. Larger estates can be phased building by building around the people who use them.
Records are where multi-site compliance often slips. Each visit produces a dated report with photos, ready to show insurers, fire officers or EHOs.
What happens if it’s left?
A fire in a greasy duct is hard to reach and hard to stop. It can travel through the ductwork to other parts of the building, so cleaning the duct is as important as cleaning the hood. Planning ahead in Lisson Grove lets you pick a quiet night rather than lose a busy one.
Several systems or sites on one quote often makes better use of the time. Mention every system or site you need covered, and you’ll get one fixed quote.

FAQs for Lisson Grove
Who enforces fire safety at workplaces in Lisson Grove?
Lisson Grove is in the area of London Fire Brigade. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
Do you do school kitchen extract cleaning in Lisson Grove in the summer holidays?
Yes. The holidays are the usual time for school work. With about 71 schools and colleges on the FSA’s register within roughly a mile and a half of Lisson Grove, it pays to plan holiday dates ahead. Booking early in the term gives the best choice of holiday dates.
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.
Do we have to stop cooking while the ducts are cleaned?
Out of hours, at a time that suits the kitchen. Larger systems may be cleaned over several nights, with the kitchen ready to cook each morning.
Can you fit access panels in our ductwork?
Yes, we do. We’ll point out where panels are needed, and we can fit them so those sections are cleaned in future.
Can you come out in an emergency?
Yes. There’s a 24/7 emergency line, for problems that can’t wait. Ring any time and tell us what’s happened.
Is Lisson Grove in your area?
Yes. Our technicians work in Lisson Grove, within the South East and London area we cover.
What happens if you cannot reach some of it?
They’re listed in the report, never skipped quietly. The report says which parts couldn’t be reached and why, and we can quote to improve the access.
Grease, kitchens and Lisson Grove
There are about 1,570 cafés, restaurants and staff canteens and about 288 sandwich bars and takeaways within 1.5 miles or so of the middle of Lisson Grove, according to the Food Standards Agency’s register. The duct above a busy canopy coats itself in grease long before anyone sees it. Kitchens in Lisson Grove get their food hygiene inspections from Westminster council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Our report lists what was cleaned and when, which is useful to have ready. The fire and rescue service for Lisson Grove is 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.
Term dates shape school work: for a school like Gateway Academy, an extract clean fits neatly into a half-term or summer break. If you cook for passing trade around London Marylebone station, the extract can be cleaned between your last and first customer.

Staff cleaning versus specialist work
When your team notices a problem 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.
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
