About our extract fan cleaning in Wilmington
Duct Doctor has been cleaning kitchen extract fans since 2009. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we are fully insured, with CHAS, SafeContractor and ISO 9001. Common call-outs are for a fan coated in grease inside its housing and vibration from an unbalanced impeller, on axial fans, in-line fans and discharge points.
Somewhere as small as Wilmington, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Every one of them still needs its extract kept clear of grease.
The paperwork matters as much as the work. Each visit is written up with photos, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

What happens on the day
We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool first, and the area around the work is covered and protected. The work itself takes an hour or two for most single fans. In a small place like Wilmington, the journey is planned ahead and the visit arranged around the site’s hours.
- 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.
- Blades, housing and surrounds are degreased with care around the electrics.
- It’s closed up, run, checked and photographed for the report.
How to prepare
- Name a contact who can let us in at the agreed time
- Mention any sign-in, permit or induction we need
- Dig out any earlier paperwork for the system

Advice
Fixed quotes for extract fan cleaning in Wilmington
Sites vary more than people expect. What affects the quote:
- The condition of the system
- When the work can happen, such as evenings, overnight or weekends
- Travel, parking and unloading
- How big the system is
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we will explain each part.
Asking for a quote
To help us quote quickly, send us:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Close-ups of filters, grilles, hatches or access panels
- Your opening hours and when the area is out of use
- Your last certificate, test record or report
Quotes are quick. Call or email with a few details and you’ll typically have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.
Common questions in Wilmington
Do you work in villages like Wilmington?
Yes, smaller places are covered as well as towns. A survey first, from photos or a visit, means we arrive with the right kit.
Do you clean school canteen extracts around Wilmington out of term?
Yes, and it’s the easiest time to do it. With about 18 schools and colleges on the FSA’s register within roughly a mile and a half of Wilmington, it pays to plan holiday dates ahead. Send us your term dates when you give us a ring on 0345 646 2711, or email photos, and we’ll fit the work in.
Which sectors do you work in?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, plus food production and leisure sites.
What does TR19 mean?
TR19® is the BESA specification for keeping ventilation systems clean. 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 long is a fan clean?
Allow a couple of hours per fan, depending on its size and the build-up. We will confirm the time when we quote.
How much does extract fan cleaning cost in Wilmington?
The cost depends on the size of the system, its condition, access and timing. Call for a fixed quote, usually ready within one working day.
Is the fan isolated during cleaning?
The fan is isolated before we open it, so it can’t start while we work. With the extract off, the kitchen can’t cook, so we work out of hours.
Can the work be done while we are closed?
Yes, and it’s often the best time. We book the visit for when the area is out of use, whether that is late evening, overnight or a weekend.
Why it’s worth doing now in Wilmington
Vibration from an unbalanced impeller does not stay small. It wears bearings and mounts and can lead to a breakdown, which may leave the kitchen without extraction. A planned clean beats an emergency. Rural sites cannot always move to another kitchen or room when something fails.
You won’t find a price list here, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll explain what it covers.
Why Wilmington businesses choose us
- A written report with photos after every visit
- A fixed price before any work starts
- Evenings, overnight and weekends, plus 24/7 emergency callout
- A BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease

When something else is needed
Before you book, it helps to know what’s not included:
- Electrical faults in the fan’s supply or controls (an electrician’s job)
- A dirty duct upstream of the fan
- A fan that was never right for the kitchen
Not sure which it is? You can phone us on 0345 646 2711, or email photos and we’ll tell you honestly before you book.

Part by part
Roof-mounted fans
Grease can escape from a roof fan onto the surrounding surface and we check the area around the outlet. Heavy staining is noted on the report.
Kitchens with long cooking hours
Kitchens that cook 12 to 16 hours a day put the most grease through their fans. BESA guidance sets at least 3-monthly cleaning for that level of use, fan included.
Looking after it afterwards
To keep the system working properly between visits:
- Listen for new noises or vibration from the fan
- Note any drop in extraction at the canopy
- Check the report shows the fan was cleaned
- Report grease escaping from the fan
A full system clean includes a TR19 certificate from the BESCA Vent Hygiene Elite portal. A fan-only clean is recorded in the photo report.
The fan stays cleaner when less grease gets past the canopy. Clean, well-seated filters are the fan’s first protection, and replace any that are damaged.
Kitchen extracts in Wilmington
There are about 49 restaurants, cafés and canteens and about 43 takeaways and sandwich shops in Wilmington and the streets around it, up to about 1.5 miles out, according to the Food Standards Agency’s register. Each kitchen extract among them ends at a fan, and grease on the impeller strains the motor. Fire safety in Wilmington falls to Kent Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. Food hygiene inspections in Wilmington are the job of Dartford council’s environmental health team. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. A dated certificate in the maintenance file answers the question before it’s asked.
If you run catering at a historic house or estate in the area (Hall Place and Gardens is about 1.7 miles north-west), event kitchens in older buildings often have awkward duct runs that need planning. Term dates shape school work: for a school like Wilmington Grammar School for Girls, an extract clean fits neatly into a half-term or summer break. Church and community hall kitchens, near St Barnabas or anywhere around Wilmington, are easy to forget, but their extracts collect grease like any other.

Staff cleaning versus specialist work
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
