Your questions about ductwork cleaning in Greenhithe
Who is the fire and rescue service for Greenhithe?
Fire safety enforcement in Greenhithe is handled by Kent Fire and Rescue Service. TR19® is not law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
Which council inspects kitchens in Greenhithe?
That’s Dartford council, whose environmental health officers carry out food hygiene inspections in Greenhithe. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
What types of premises do you cover?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, plus food production and leisure sites.
How much does ductwork cleaning cost in Greenhithe?
Size, condition, access and working hours all affect the cost. Ask us for a fixed quote and we’ll usually reply within one working day.
Do we have to stop cooking while the ducts are cleaned?
When the kitchen is closed. Larger systems may be cleaned over several nights, with the kitchen ready to cook each morning.
What if parts of the system cannot be reached?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, and we can fit those.
What’s the cleaning interval for extract ductwork?
The minimum depends on how long the kitchen cooks each day: 3-monthly for heavy use, 6-monthly for moderate and 12-monthly for light use. Measured grease sets the real interval.
How can I tell if my extract ducts are dirty?
A grease thickness test gives the answer. Using a Wet Film Thickness Test or Deposit Thickness Test, we check the grease at set points. BESA guidance says the mean shouldn’t exceed 200 microns, and 500 or more anywhere needs immediate spot cleaning.
About our ductwork cleaning in Greenhithe
No two duct runs are the same, in Greenhithe or anywhere else. A few metres to an outside wall, or a riser up through the building to a roof fan. The survey traces the route, so we know where to get in and how long it will take. If you are dealing with a grease test showing the duct is overdue and a rancid smell from the extract duct, we can put it right, from vertical risers, bends and junctions and horizontal duct runs onwards.
In a smaller place like Greenhithe, many kitchens sit in older buildings or later extensions, with the duct running through a roof space or up an outside wall. Long horizontal runs like that hold grease and need access panels to reach.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

What affects the quote in Greenhithe
Sites vary more than people expect. What affects the quote:
- The times the site is available
- Site rules, permits and inductions
- The condition of the system
- How easy every part is to reach
Working hours, access and the scale of the site all affect the cost. We take each of them into account, and the price is fixed before work begins.
What we need to know
What to send for a quote:
- Your last certificate, test record or report
- The site address and the type of premises
- When the site is open and when it’s quiet
- Photos showing the whole system and its surroundings
Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, you get a fixed price before any work starts.
Part by part
Vertical risers
Risers carry the extract up through the building to the roof. Grease runs down the walls and gathers at the base, which is one of the points we test.
Bends and transitions
Bends, elbows and changes of size are where grease collects most. Slowing air leaves grease behind, so we clean these points carefully.

Between visits
Think of this as the after-treatment advice, short and simple:
- Make sure filters are seated properly
- Flag drips from the duct right away
- Keep access panels clear of stored items
- Book the next clean before the recommended date
When the duct is cleaned as part of a full TR19® Grease clean, a TR19 certificate is issued through the BESCA Vent Hygiene Elite portal. It shows when and where the clean was done and by whom.
The less grease gets past the canopy, the cleaner the duct stays. Keep the filters clean, well fitted and in place whenever you cook.
Common problems we fix in Greenhithe
Grease filters that do not seal let fat straight through. More grease reaches the ductwork than it should and it fills faster.
It’s time to book a visit if you see:
- Grease seeping out of the duct seams
- Readings above 200 microns from a grease thickness test
- Ductwork that has never been cleaned
- Heavy grease at the base of a riser
Bursars and site managers at schools such as Knockhall Primary School tend to book extract cleaning for when the kitchen is empty.
Before you book anyone

Why act early in Greenhithe
TR19® isn’t law, but the duty to manage fire risk is. Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and grease in the duct is part of that. Light use slows the build-up but doesn’t stop it.
You will not find a price list here, because the cost depends on the site in front of us. For a fixed quote, call 0345 646 2711, or email photos, and we’ll talk you through it.

Multi-site and managed buildings
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We can quote either party and send the paperwork to whoever needs it.
From a single site to a large estate, the standard is the same: a survey first, a fixed quote, the work timed around the site and a report with photos.
Ductwork cleaning in Greenhithe: the local picture
The FSA’s food hygiene register shows about 72 restaurants, cafés and canteens and about 20 takeaways and sandwich shops within about 1.5 miles of central Greenhithe. Each kitchen that cooks under a canopy sends grease-laden air into a duct, where it cools and settles. The fire and rescue service for Greenhithe is Kent Fire and Rescue Service. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract. In Greenhithe, food businesses are inspected by environmental health officers from Dartford council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
Church and community hall kitchens, near Church of St Mary or anywhere around Greenhithe, are easy to forget, but their extracts collect grease like any other. Healthcare kitchens can’t easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Greenhithe is Darent Valley Hospital, about 1.5 miles south-west.

How the visit works
The visit has three parts: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and pictures. The middle part takes longest, which takes from a few hours to more than one visit, depending on duct length and access. Your opening hours decide when we come to Greenhithe, not ours.
- We map the duct route and check where the access panels are.
- We measure grease thickness at set points before cleaning.
- We open the panels and scrape out the heaviest grease.
- 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.
Before we arrive
- Let us know about permits to work or site inductions
- Mention any locked doors, roof access or ceiling voids
- Let us know when the site is closed or quiet
