About our extract fan cleaning in Darenth
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. If you are dealing with a fan shaking on its mounts and a fan that hums, whines or rumbles, we can help, from centrifugal fans, fan housings and in-line fans onwards.
Work in a small place like Darenth starts with a call to agree access and timings, and the clean itself is the same full TR19® job as in any town: canopy to discharge, then a TR19® certificate and a photo report.
Think of the report as the system’s health record: a dated account with photos of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

What we do, step by step
The visit has three parts: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, while signing off means the written report and photos. Most of the time goes on the work itself, and that takes a few hours where there are several fans or heavy deposits. Somewhere like Darenth, lanes, gates and parking are worth mentioning in advance.
- First we check the fan’s condition and how it sounds.
- Once isolated, we open the fan up.
- Each blade is cleaned so the impeller runs evenly.
- Housing, outlet and the area around the motor are cleaned.
- We run the fan and note its condition in the photo report.
How to prepare
- Have your last certificate or report to hand
- Clear loose items from the work area
- Tell us where we can park and unload

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 work begins.

What extract fan cleaning can’t fix
We won’t sell you work that does not address the problem, so these are the things it will not cover:
- Wiring faults to the fan
- A motor that has burnt out
- A cracked or broken impeller (it needs replacing)
Not sure which it is? You can ring 0345 646 2711 or use the quote form and we’ll tell you honestly before booking.
Parts of the system we cover
- Axial fans
- Discharge points
- Roof-mounted fans
- In-line fans
- Fan housings
- Centrifugal fans
Multi-site and managed buildings
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side and send the paperwork to whoever needs it.
We also work for facilities teams across offices, schools and healthcare in Darenth and across Kent. Larger estates can be phased building by building to keep disruption down.
Part by part
Kitchens with long cooking hours
When a busy kitchen’s fan fails, cooking stops. A clean fan is less likely to strain, and our 24/7 emergency callout is there if it happens anyway.
Impellers and blades
Coated blades move less air. Scraping and degreasing them restores their shape, so the fan can run as intended.
In-house cleaning or a specialist?
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
Looking after it afterwards
Think of this as the after-treatment advice, short and simple:
- Keep the fan on whenever the range is lit
- Note any drop in extraction at the canopy
- Keep each photo report with the maintenance log
- Never cook with a filter missing
File the photo report with your other extract records. It gives a dated record of the fan’s condition, which helps if anything changes later.
A change in how the fan sounds is worth noting. Rattles, hums or shaking can be early signs of build-up or wear, and catching it early keeps it a cleaning job.
What affects the quote in Darenth
Your quote is based on your site. We consider:
- Site requirements such as sign-in and permits
- Where the site is and how we reach it
- The number of sites or systems
- The times the site is available
Kitchens, offices, schools and hospitals are all priced 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 go through it with you.
What to send for a quote
We can often survey from photos. Try to include:
- A few general shots of the system
- Any access panels or hatches you can see
- The paperwork from the last visit, if you have it
- The roof, plant room or outside wall the system runs to
Quoting starts with a diagnosis, from your photos and details or, where that is not enough, a survey on site. Then we send a fixed price so you know the cost before any work starts.

Questions from Darenth
Which council inspects kitchens in Darenth?
The local authority for Darenth is Dartford council, and its environmental health team does the inspecting. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
Can you work in Darenth outside opening hours?
Yes, evening, overnight and weekend work is normal for us. Your customers, staff or residents in Darenth needn’t be disturbed. Tell us your opening hours when you ask for a quote.
What do you do to protect the area?
With sheeting and covers, before anything else happens. We keep the work contained and clean down when we finish.
Which accreditations do you hold?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.
Does a TR19 kitchen extract clean cover the fan?
Yes. The whole system is cleaned, from the canopy to the discharge, and the fan sits right in that path, so it’s cleaned too.
Do you have insurance?
Yes. We are fully insured, and the details are available on request.
Is the fan isolated during cleaning?
We isolate the fan, so the kitchen cannot cook while we work. We work evenings, overnight or weekends, and the kitchen is ready when we leave.
Can the fan be cleaned between full cleans?
Yes, where it makes sense. A coated fan often means the duct before it is coated too, but the choice is yours.
Kitchen extracts in Darenth
Food Standards Agency records list about 54 cafés, restaurants and staff canteens and about 16 takeaways within 1.5 miles or so of the middle of Darenth. The fan at the end of each of those extracts collects grease that slows it and wears the motor. Kitchens in Darenth get their food hygiene inspections from Dartford council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Before-and-after photos from each clean are a simple way to show the extract is in hand. Darenth 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.
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Darenth Park Hospital is the nearest hospital to Darenth, about 1 mile north. Term dates shape school work: for a school like Greenlands Primary School, an extract clean fits neatly into a half-term or summer break. If your kitchen is in a listed or historic building, like the houses around Darenth (Hall Place and Gardens is about 4.6 miles north-west), fitting access panels needs care.
