How we handle ductwork cleaning in Stone
In doctor’s terms, the ductwork is the system’s arteries: diagnose where grease has built up, clear it and confirm the result. Readings taken before and after show the difference, alongside before and after pictures. The work covers vertical risers, multi-storey ducts and horizontal duct runs, and people most often call us about stale grease odours from the duct and an insurer asking for TR19 evidence.
Around a smaller place like Stone, kitchen extracts tend to belong to pubs, cafés, takeaways and school or care home kitchens. A kitchen that cooks fewer hours still builds up grease, so the interval is set by hours of use and grease readings.
Nothing is signed off by word of mouth: a dated report with pictures of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

How the visit works
Your staff do not need to do much on the day. Someone lets us in at the agreed time and shows us where everything is, and the rest is down to us. Afterwards, the area is left tidy and the written report follows. Because the survey comes first, a visit to Stone can usually be finished without a second trip.
- The duct route is surveyed and every access point found.
- 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.
Before we arrive
- Find the previous report, if there is one
- Plan for cooking equipment or plant to be off before we arrive
- Tell us about site rules, permits or sign-in

What staff can safely do
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.

Grease, kitchens and Stone
According to Food Standards Agency records, there are about 12 pubs, bars and clubs and about 4 hotels, B&Bs and guest houses in Stone and the streets around it, up to about 1.5 miles out. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Environmental health officers from Dartford council inspect food businesses in Stone. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Before-and-after pictures from each clean are a simple way to show the extract is in hand. Kent Fire and Rescue Service covers Stone. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.
Healthcare kitchens, like those at hospitals such as Darent Valley Hospital (about 1 mile south-west), often cook for long hours, which puts them in BESA’s heavier-use bands. Bursars and site managers at schools such as Stone St Mary's CofE Primary School tend to book extract cleaning for when the kitchen is empty.

Do you need ductwork cleaning in Stone?
Air cools as it moves away from the canopy. As it cools, the grease it carries condenses onto the duct walls, which is why ducts go on gathering grease well beyond the filters.
These are the problems we see most often:
- Gaps where access panels were never fitted
- A duct clean needed for an insurer
- Years of grease along the duct floor
- Grease pooling at the foot of the riser
If you cook for passing trade around Stone Crossing station, the extract can be cleaned between your last and first customer.

Keeping the system healthy
Simple habits between visits make a real difference. Our advice:
- Leave a way through to the access panels
- Never cook with a filter missing
- Flag drips from the duct right away
- Get panels fitted where the duct couldn’t be cleaned
You’ll have a recommended date for the next clean, based on the readings and your daily cooking hours, in line with BESA guidance.
Extra access panels mean more of the duct gets cleaned each time. Grease you can reach is grease that gets removed.
Honest limits
Not every problem is solved by ductwork cleaning, and we’ll tell you before any work starts. It does not solve:
- Undersized or badly laid-out ducts
- Sections that cannot be reached safely without new access (those are recorded, and panels can be fitted)
- Faulty fire dampers
Not sure which it is? You can give us a ring on 0345 646 2711, or email photos and we’ll tell you honestly before booking.

Stone: your questions answered
Which fire authority looks after Stone?
Stone is in the area of Kent Fire and Rescue Service. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
Do you clean school canteen extracts around Stone out of term?
Yes. The holidays are the usual time for school work. The FSA’s register shows about 5 schools and colleges with food registrations within roughly a mile and a half of Stone. Send us your term dates when you call us on 0345 646 2711 or email us, and we will fit the work in.
How far ahead should we book?
Earlier is better, especially for out-of-hours work. Quotes normally come back within one working day, and there’s a 24/7 line for emergencies.
Can you fit access panels in our ductwork?
Yes, we do. We will point out where panels are needed, and we can fit them so those sections are cleaned in future.
When is the ductwork cleaned?
Only while we’re working, and we work around you. Most kitchens book overnight or weekend cleans, so no service is lost.
Do you have a 24/7 line?
Yes. There’s a 24/7 emergency line, for problems that cannot wait. Ring any time and tell us what’s happened.
What do you need from me for a quote?

Do you have insurance?
Yes. Duct Doctor is fully insured, and the details are available on request.
How the job changes from site to site
Horizontal duct runs
Horizontal runs carry the extract along ceilings and through voids. Grease drops out of the slowing air along them, and we clean them section by section through access panels.
Vertical risers
Cleaning a riser needs access along its height. Where it cannot be reached safely, the report says so.
