Ductwork cleaning in Stonehill Green
Ductwork in Stonehill Green is cleaned the same thorough way as everywhere else we work: we test the grease first, remove thick deposits by hand and degrease what’s left. Readings are taken again afterwards and photos go into your report. Common call-outs are for an insurer asking for TR19 evidence and duct runs that can’t be reached, on attenuators, horizontal duct runs and access panels.
In a small place like Stonehill Green, kitchens are often in older or extended buildings, with long single-storey duct runs, and those horizontal sections are where grease settles. We agree access and timings in advance.
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.

Why deal with it now?
A partly blocked duct slows the airflow. Less air moves, so heat and smoke stay in the kitchen while the fan strains and grease can drip from duct joints. Out of sight is the usual reason a rural system goes too long without attention.
The price reflects the work, not guesswork. That is why we survey first, from photos or on site, and the price is agreed before any work starts.

Ductwork cleaning in Stonehill Green: the local picture
The FSA’s food hygiene register shows about 20 cafés, restaurants and staff canteens and about 12 takeaways in and around Stonehill Green, up to about a mile and a half out. The duct above a busy canopy coats itself in grease long before anyone sees it. It’s Dartford council that sends environmental health officers to food businesses in Stonehill Green. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Keeping each certificate and photo report on file helps show the extract is looked after. Stonehill Green sits within the area of 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.
School kitchens, at schools like Hextable School for example, are normally cleaned in the holidays so no lunches are lost. A hall kitchen that only cooks for events, whether near St Peter or elsewhere in Stonehill Green, still needs its extract cleaned, just less often.

Questions from Stonehill Green
Do you work in villages like Stonehill Green?
Yes, we work in villages as well as towns, and Stonehill Green is covered. Just mention lanes, gates or anything else about the site when you book.
Which fire authority looks after Stonehill Green?
Kent Fire and Rescue Service is the fire and rescue service for Stonehill Green. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Will the duct clean disrupt the kitchen?
We clean while the kitchen is closed, evenings, overnight or at weekends. The extract and cooking equipment need to be off.
What accreditations do you have?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We have been trading since 2009 and we are fully insured.
How much notice should we give?
It depends on the time you need and how big the job is. Mention your preferred dates with your enquiry, and if it’s an emergency, call us any time.
How much does ductwork cleaning cost in Stonehill Green?
The cost depends on the size of the system, its condition, access and timing. Call for a fixed quote, typically ready within one working day.
How can I tell if my extract ducts are dirty?
Drips, smells and weak extraction are clues, but the only sure way is to measure. Grease thickness testing shows exactly where the duct stands.
What is TR19?
TR19® is BESA’s specification for ventilation hygiene. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.

How the job changes from site to site
Bends and transitions
Wherever the duct turns or changes size, grease builds up. Slowing air leaves grease behind, so these points get extra attention.
Multi-storey and shared buildings
Long ducts in larger buildings can mean several visits. Visits are planned around the building’s hours, out of hours where possible.
Common problems we fix in Stonehill Green
Grease settles fastest where the air slows down. Long horizontal runs, bends, changes in size and the foot of a riser all collect more, and those are the points we pay most attention to.
The symptoms we are asked about most are:
- High readings at a recent grease test
- Duct runs that can’t be reached
- A duct nobody has opened in years
- Grease pooling at the foot of the riser
If you run catering at a historic house or estate in the area (Hall Place and Gardens is about 2.4 miles north), event kitchens in older buildings often have awkward duct runs that need planning.
Comparing quotes
- What insurance they carry
- How VAT is shown on the quote
- How they set the interval to the next visit
- Whether a written report and photos are included
How the visit works
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool first, and floors and nearby surfaces are sheeted. The work itself takes from a few hours to more than one visit, depending on duct length and access. Pictures of the system and its access let us plan the work in Stonehill Green before we set off.
- The duct route is surveyed and every access point found.
- Grease thickness is measured at set points.
- Out of hours, the area is protected and the access panels opened.
- Thick grease is scraped out, then the runs and risers are degreased.
- Panels are closed, readings and photos repeated, and unreachable sections recorded.
Preparing for the visit
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Mention any sign-in, permit or induction we need
- Mention any parking or loading restrictions
Get a fixed quote
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 we start.

Managing agents and facilities teams in Stonehill Green
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Each site gets its own report and pictures, so records stay tidy.
Whether it’s one building or many, you get the same standard: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
Keeping the system healthy
So the system stays in good health:
- Keep grease filters clean and fitted whenever you cook
- Get panels fitted where the duct couldn’t be cleaned
- Keep access panels clear of stored items
- Check readings when the menu changes
File the paperwork in the maintenance log. An insurer, fire officer or EHO may ask to see it, and the pictures make the duct’s condition easy to see.
Book the next duct clean before the date passes. A change in cooking hours may change the interval under BESA guidance, and grease thickness testing will show it.
