Ductwork cleaning in Winchmore Hill
The ductwork is where an extract clean is won or lost. Sections with no way in can go uncleaned for years. We open up every reachable section and record any we can’t reach, so you know exactly where you stand. The work covers attenuators, access panels and horizontal duct runs, and the jobs we see most are a grease test showing the duct is overdue and stale grease odours from the duct.
In London, few kitchens can spare a day to close, so extract cleaning in Winchmore Hill 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.
We’ve been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

Kitchen extracts in Winchmore Hill
There are about 170 restaurants, cafés and works canteens and about 44 takeaways across Winchmore Hill and its immediate surroundings (about a mile and a half), according to the Food Standards Agency’s register. Wherever those kitchens cook under a canopy, the horizontal runs and risers need cleaning as well as the hood. Winchmore Hill sits within the area of London Fire Brigade. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. Kitchens in Winchmore Hill get their food hygiene inspections from Enfield council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Before-and-after photos from each clean are a simple way to show the extract is in hand.
A kitchen near Winchmore Hill station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval. If you look after a school kitchen, at a school such as St. Paul's School or anywhere near Winchmore Hill, the holidays are the usual time for a TR19® clean.

What we’re called out for in Winchmore Hill
Damaged or poorly fitted filters let more grease into the duct. The duct then takes grease that the filters should have stopped and it fills faster.
The symptoms we are asked about most are:
- Heavy grease at the base of a riser
- Gaps where access panels were never fitted
- Stale grease odours from the duct
- Years of grease along the duct floor
Volunteers running a hall kitchen near Holy Trinity, or anywhere in Winchmore Hill, may not know when the extract was last cleaned, and a grease test settles it.

Staff cleaning versus specialist work
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.

Winchmore Hill: your questions answered
Can you come to Winchmore Hill after we close?
Yes, we can come after you close and finish before you open. That way a site in Winchmore Hill does not have to lose a day’s trading. Let us know the hours you are closed and we’ll book within them.
Which environmental health team covers Winchmore Hill?
Food hygiene inspections in Winchmore Hill are carried out by Enfield council. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.
Which accreditations do you hold?
We hold CHAS, SafeContractor and ISO 9001, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
How much does ductwork cleaning cost in Winchmore Hill?
We don’t publish prices, because the cost depends on the job: the size of the system, its condition, access and when we can work. You get a fixed price before any work starts.
How do you know if the ductwork needs cleaning?
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.
What do you do with what you remove?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. We do not leave it behind.
Do you survey before quoting?
Yes, every time. We diagnose before we treat: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
What should I send you?
Only a few details: where it is, what kind of site, when it’s open and the access. Photos and any previous paperwork make it quicker. After that, simply call 0345 646 2711 or send us an email.
What affects the quote in Winchmore Hill
The price is fixed before any work begins. It takes into account:
- How many systems or sites are involved
- How easy every part is to reach
- Site requirements such as sign-in and permits
- The times the site is available
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you’re not sure what’s needed, call us on 0345 646 2711 or send us an email and we will give you an honest view and a fixed quote.
What to send for a quote
Before you ask for a quote, gather:
- The times we could work without disrupting the site
- Close-ups of filters, grilles, hatches or access panels
- Any symptoms, from odd noises to smells or leaks
- The roof, plant room or outside wall the system runs to
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before work begins.
How the visit works
There are three stages on the day: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, while signing off means the written report and photos. Most of the time goes on the work itself, which takes anything from a few hours to several visits, depending on the length of duct. In a London area like Winchmore Hill, parking, loading and building access are planned before the day of the work.
- 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.
- Thick grease is scraped out, then the runs and risers are degreased.
- We close up, re-test, photograph and record anything out of reach.
Getting ready for the visit
- Mention any locked doors, roof access or ceiling voids
- Tell us about site rules, permits or sign-in
- Arrange a key holder or contact on site
Get a fixed quote
We do not publish a price list, because no two systems are the same. Instead, we look at your site first, from photos or a survey, and then send you a fixed quote. To get going, call us on 0345 646 2711 or email us.
Advice
Looking after it afterwards
So the system stays in good health:
- Ask us about extra access panels where sections can’t be reached
- Ask for a grease thickness test if the kitchen gets busier
- Keep access panels clear of stored items
- Flag drips from the duct right away
Grease readings are taken again at the same set points, giving you before and after readings. Photos of each section go alongside them.
The less grease gets past the canopy, the cleaner the duct stays. Clean, properly seated filters are the duct’s best protection.
For landlords and multi-site operators
We also work for facilities teams across offices, schools and healthcare across Greater London. Work can be phased by floor, building or site around the people who use them.
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side and send the paperwork to whoever needs it.
Why it’s worth doing now in Winchmore Hill
Grease narrows the duct and slows the air. Less air moves, so heat and smoke stay in the kitchen while the fan strains and grease can drip from duct joints. Shared walls, risers and roofs mean a problem at one London site seldom stays put.
Combining work into one visit or one programme often makes better use of the time. Tell us about everything you’d like looked at, and you will get one fixed quote.
