In-house cleaning or a specialist?
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.
Extract fan cleaning in Stone
Cleaning removes grease, not wear. Anything that looks worn or damaged goes on the report and fan repair or replacement is something we also do. You get an honest view of the fan’s condition. If you’re dealing with grease escaping from the fan outlet and a smell of hot grease from the extract, we can help, from axial fans, in-line fans and fan housings onwards.
In a smaller place like Stone, the kitchens with extract systems are more likely to be a pub, a café, a takeaway or a school or care home kitchen than a big restaurant. Quieter kitchens still collect grease in the duct, just more slowly, so cleaning is planned around how much it cooks and what the readings show.
It’s worth checking any contractor’s accreditations. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

Kitchen extracts in Stone
The Food Standards Agency lists about 12 pubs and bars and about 4 hotels and guest houses as registered food businesses within about 1.5 miles of central Stone. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Food hygiene inspections in Stone are the job of Dartford council’s environmental health team. Extraction counts as kitchen equipment, so its condition can come up on the day. A TR19® certificate and photo report after each clean gives you a record to show an inspector. The fire and rescue service for Stone 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.
If you run a café or takeaway near Stone Crossing station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits. School kitchens, at schools like Stone St Mary's CofE Primary School for example, are usually cleaned in the holidays so no lunches are lost.

Stone: your questions answered
Do you work at weekends in Stone?
Yes, out-of-hours work is a big part of what we do. That way a site in Stone doesn’t have to lose a day’s trading. Let us know the hours you’re closed and we will book within them.
Do you cover smaller places like Stone?
Yes, Stone is part of our area, however small the site. A survey first, from photos or a visit, means we arrive with the right kit.
Can you look after several sites?
Yes. Tell us the addresses and what each needs and you will get one fixed quote.
How long does extract fan cleaning take?
A single accessible fan doesn’t take long, while fans on high roofs or in tight voids take longer. It’s done while the kitchen is closed.
Are you accredited?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.
Why is my extract fan noisy?
Uneven grease on the impeller often causes it. After cleaning, we’ll tell you if wear or damage is also involved.
Who is the responsible person?
In the words of the Fire Safety Order 2005, it’s the responsible person. That’s generally the employer or the person in control of the premises, and in shared buildings more than one person can have duties. If you’re not sure, check your lease and fire risk assessment.
What types of premises do you cover?
Commercial premises of every kind: kitchens, offices, schools, healthcare, retail, leisure and food production. We fit the work around how the site operates.
Between visits
After the visit, a few habits help the work last:
- Do not turn the fan off mid-service
- Report rattles or humming early
- Keep access to the fan clear
- Keep the grease filters clean and in place
When we have finished, the fan is reassembled and run. If anything seems wrong, from vibration to wear, we note it, so you can plan any repair.
Keep the route to the fan clear. A fan that can be reached safely is a fan that gets cleaned, whether it’s on a roof, in a ceiling or on a wall.
What happens on the day
When we arrive, we check the system against the survey or the photos you sent. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes an hour or two for most single fans. For a place like Stone, we load the van from the survey notes so the work can be done in one visit where possible.
- We locate the fan and plan how to reach and isolate it.
- We isolate the power before opening the housing.
- Grease is scraped off the impeller blades and casing.
- The fan is degreased, taking care around the motor.
- It’s closed up, run, checked and photographed for the report.
Preparing for the visit
- Let us know about parking and loading
- Tell us the best time to work, such as after service or at a weekend
- Make sure someone can let us in and lock up afterwards
Getting a quote
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.

- Working hours and out-of-hours timing
- Site rules, permits and inductions
- Whether it’s a one-off visit or part of a schedule
- The scale of the work
The cost depends on the size of the system, what state it’s in and how easy it is to reach. We give you a fixed price before we start, so there are no surprises.
What to send for a quote
To speed up the quote, send us:
- Wide pictures of the system and the area around it

Do you need extract fan cleaning in Stone?
The cooler the air, the more grease drops out, and on a roof or outside wall the fan can be in some of the coolest air in the system. That makes it a natural place for grease to settle.
Clients usually contact us when they notice one of these:
- Fat spreading onto the roof or wall by the fan
- A fan motor running hot under a coat of grease
- Rough running from the extract fan
- Hot, greasy smells near the fan
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.
Before you book anyone
- Exactly which parts of the system are covered
- How VAT is shown on the quote
- Whether a survey comes first
- What records you’ll receive afterwards
What happens if it’s left?
A fan that fails mid-service can stop a kitchen cooking. Grease is often where fan trouble begins, so cleaning the fan helps keep it working. If it does fail, our 24/7 emergency line is there. In a smaller place like Stone, a site that has to close is felt quickly.
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.
