What we do, step by step
Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. All told, the work takes a shift or more, depending on the length of the runs and the number of access points. Getting kit into a London building takes planning, so let us know where we can load and park in Crouch End.
- We trace the duct and find every way in.
- Grease thickness is measured at set points.
- Once the kitchen has closed, we protect the area and open the panels.
- Heavy deposits come out by hand, then each section is degreased.
- Panels are closed, readings and photos repeated, and unreachable sections recorded.
How to prepare
- Mention any parking or loading restrictions
- Plan for cooking equipment or plant to be off before we arrive
- Make sure someone can let us in and lock up afterwards

Ductwork cleaning for kitchens and businesses in Crouch End
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. Common call-outs are for ductwork that has never been cleaned and readings above 200 microns from a grease thickness test, on horizontal duct runs, vertical risers and multi-storey ducts.
London kitchens tend to trade late and open early, so extract cleaning in Crouch End is usually done overnight, after the last service. Parking, loading and access to the roof are agreed with the building before the night of the clean.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Leave it or put it right?
Grease left in a duct in Crouch End hardens over time. It bakes into a hard layer that takes far longer to remove, so the later the clean, the bigger the job. In a London building, a problem in a duct, damper or fan rarely stays in one unit.
Working hours, access and the scale of the site can all change the price. We take each of them into account and give you a fixed price before any work starts.

Crouch End: your questions answered
Do you work overnight in Crouch End?
Yes. We work evenings, overnight and at weekends. It means the site in Crouch End keeps running as normal. Tell us your opening hours when you ask for a quote.
Do you do school kitchen extract cleaning in Crouch End in the summer holidays?
Yes, and it’s the easiest time to do it. The FSA’s register shows about 51 schools and colleges with food registrations within roughly a mile and a half of Crouch End. Just phone us on 0345 646 2711 or send us an email with your term dates and we will plan around them.
What is TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It sets out inspection, cleaning and record keeping, and it takes a risk-based approach.
What paperwork do you give after a duct clean?
Readings, pictures and, for a full clean, a TR19 certificate. It also gives a recommended next clean date.
What do you do to protect the area?
We start with protection: floor sheeting and covers over nearby surfaces and equipment. We tidy up and take our waste away before we leave.
Do we lose a day’s trading?
Not normally. Booking the work out of hours means the site can carry on as normal. Bigger sites can be done in stages to keep things running.
What if parts of the system can’t be reached?
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.
How do you clean inside the ductwork?
Each section is cleaned through its own panel. Grease is scraped out first, then degreased, with readings taken before and after.

Between visits
How long the results last depends on use and care. We suggest:
- Keep your cleaning records together
- Tell us if grease leaks from the ductwork
- Leave a way through to the access panels
- Ask for a grease thickness test if the kitchen gets busier
Every panel we open is refitted when we finish, and the surrounding area is left clean. Waste grease and water are taken away.
Keep the fan on throughout service. Moving air carries vapour through rather than letting it settle, so switching off early adds to the build-up.
What affects the cost of ductwork cleaning
Some jobs are bigger than they look, and some smaller. The main factors:
- Where the site is and how we reach it
- Access, including roofs, risers and ceiling voids
- A single visit or a regular plan
- What state the system is in
Combining work into one visit or one programme can make for a more efficient booking. Mention every system or site you need covered, and you’ll get one fixed quote.
What we need to know
We can often survey from photos. The most useful are:
- Your last certificate, test record or report
- How we’d reach plant on a roof or in a plant room
- The times we could work without disrupting the site
- Wide pictures of the system and the area around it

Crouch End kitchens: local notes
Food Standards Agency records include about 77 bars, pubs and nightclubs and about 6 hotels and guest houses within about 1.5 miles of central Crouch End. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. The fire and rescue service for Crouch End 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. London jobs normally start after the last service, with loading and roof access agreed with the building first.
Commuter trade near Crouch Hill station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands. Volunteers running a hall kitchen near Christ Church, or anywhere in Crouch End, may not know when the extract was last cleaned, and a grease test settles it. Healthcare kitchens, like those at hospitals such as Hornsey Central Hospital (about less than half a mile north-west), often cook for long hours, which puts them in BESA’s heavier-use bands.

Different parts, different methods
Horizontal duct runs
Flat runs of duct link the canopy to the riser or the outside wall. They collect grease as the air cools and slows, and we clean them section by section through access panels.
Attenuators and discharge
At the end of the duct is the discharge. Grease can collect there and stain the area around it, so it’s cleaned as far as safe access allows.
Managing agents and facilities teams in Crouch End
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We can quote either party and send the paperwork to whoever needs it.
What your team can do, and what needs us
Staff cleaning and specialist work are not the same thing. 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.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
