Ductwork cleaning in Longfield
Grease in a duct is hidden, which is exactly why it’s dangerous. A flare-up drawn up from the range can light it, carrying a fire along the duct and into rooms far from the kitchen. Removing it is the whole point. We are often asked to deal with grease seeping out of the duct seams and a grease test showing the duct is overdue, across attenuators, horizontal duct runs and access panels.
In a small place like Longfield, kitchens are often in older or extended buildings, with long single-storey duct runs, where grease settles in the flat sections. Access, parking and timings are agreed before the day.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

Ductwork cleaning around Longfield
Food Standards Agency records list about 6 restaurants, cafés and canteens and about 6 takeaways in Longfield and the streets around it, up to about 1.5 miles out. The duct above a busy canopy coats itself in grease long before anyone sees it. Fire safety in Longfield falls to Kent Fire and Rescue Service. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel. It’s Dartford council that sends environmental health officers to food businesses in Longfield. Extraction counts as kitchen equipment, so its condition can come up on the day. A dated certificate in the maintenance file answers the question before it’s asked.
Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Longfield is Darent Valley Hospital, about 3.3 miles north-west. If you run a church or community hall kitchen, near Church of Saint Mary Magdalene or elsewhere in Longfield, its extract still collects grease from every lunch and event. If you cook for passing trade around Longfield station, the extract can be cleaned between your last and first customer.

What staff can safely do
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Honest limits
Before you book, it helps to know what’s not included:
- An extract fan that has stopped working
- Fire dampers that don’t close (they need testing and remedials)
- Parts of the duct with no way in
If you’re not sure, just phone us on 0345 646 2711, or send details by email and we will give you a straight answer before booking.
Where we work
- Vertical risers
- Multi-storey ducts
- Horizontal duct runs
- Attenuators
- Bends and junctions
- Access panels
Part by part
Vertical risers
Risers are cleaned through panels at different levels. Where it can’t be reached safely, the report says so.
Attenuators and discharge
The discharge is where the duct ends and air leaves the building. It can gather grease and mark the wall or roof around it, so it’s cleaned as far as safe access allows.
What happens on the day
The visit has three parts: 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 pictures. Most of the time goes on the work itself, and that takes a shift or more, depending on the length of the runs and the number of access points. Seeing the system in photos first means the trip to Longfield can be planned properly.
- First the duct route is traced and every access point noted.
- We measure grease thickness at set points before cleaning.
- Access panels are opened and heavy deposits scraped out by hand.
- The duct is degreased with the method that suits the grease, from degreasers to hot water or steam.
- Readings and photos are repeated and any section we couldn’t reach is recorded.
Getting ready for the visit
- Mention any parking or loading restrictions
- Let us know how we reach the system, including roofs, risers and plant rooms
- Find the previous report, if there is one

Advice
Between visits
After the visit, a few habits help the work last:
- Leave a way through to the access panels
- Report any grease dripping from duct joints
- Never cook with a filter missing
- Keep the fan on while anything is cooking
You will have a recommended date for the next clean, based on the readings and your daily cooking hours, in line with BESA guidance.
Some signs mean the duct needs attention sooner: grease leaking from duct joints, smells, or a fan that sounds rough. A grease thickness test can confirm whether a spot clean is needed.

Common questions in Longfield
Can the work in Longfield be done at night or at weekends?
Yes, out-of-hours work is a big part of what we do. It means the site in Longfield keeps running as normal. Tell us your opening hours when you ask for a quote.
Who inspects food businesses in Longfield?
That’s Dartford council, whose environmental health officers carry out food hygiene inspections in Longfield. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.
Who is the responsible person?
Under the Regulatory Reform (Fire Safety) Order 2005, it’s the responsible person: normally the employer or whoever controls the premises. In shared or managed buildings, a landlord, facilities manager or managing agent can share the duty.
Will I get a report after the ducts are cleaned?
You get a photo report with before and after pictures, and a full TR19 clean also comes with a certificate issued through the BESCA Vent Hygiene Elite portal. Keep both in the maintenance log.
Which sectors do you work in?
Any commercial site with kitchens or ventilation, from a small pub to a hospital. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
Do we need to close while you work?
Not typically. Visits are timed for when the area is closed, such as overnight or at a weekend, so the site can carry on as normal.
Do you survey before quoting?
Yes. For many sites, photos and a few details are enough, while bigger or harder-to-see systems are surveyed on site.
How do you know if the ductwork needs cleaning?
We measure it. Readings are taken by Wet Film Thickness Test (WFTT) or Deposit Thickness Test (DTT). BESA guidance says the mean shouldn’t exceed 200 microns, and 500 or more anywhere needs immediate spot cleaning.
