Extract Fan Cleaning in Headstone
Extract fan cleaning in Headstone from ventilation hygiene specialists trading since 2009. Out-of-hours visits and 24/7 emergency callout.
- An extract fan with no cleaning record
- Grease escaping from the fan outlet

Leave it or put it right?
Vibration from an unbalanced impeller does not stay small. It wears bearings and mounts and can lead to a breakdown and a kitchen can’t cook safely without extraction. Cleaning it early is far less disruptive. Planning ahead in Headstone lets you pick a quiet night rather than lose a busy one.
When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account, and the price is fixed before any work starts.
What you get with us

Extract fan cleaning in Headstone, done properly
Grease on a fan isn’t spread evenly. Heavier deposits on some blades throw the impeller off balance, which brings vibration, noise and extra wear on the bearings and motor. Cleaning the impeller and housing puts that right. The work covers axial fans, roof-mounted fans and discharge points, and the jobs we see most are a noisy fan that has got louder over time and grease escaping from the fan outlet.
In London, few kitchens can spare a day to close, so extract cleaning in Headstone is usually done overnight, after the last service. Before the clean, we agree loading, parking and roof access with whoever manages the building.
Duct Doctor has been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

Extract fan cleaning around Headstone
According to Food Standards Agency records, there are about 12 bars, pubs and nightclubs across Headstone and its immediate surroundings (about a mile and a half). A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Most London extract cleaning happens at night, after the last service. Food hygiene inspections in Headstone are the job of Harrow 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.
If you cook for passing trade around Headstone Lane station, the extract can be cleaned between your last and first customer. For schools such as Pinner Park Primary School, kitchen extract cleaning is normally booked for the holidays, when the canteen is closed.

How the visit works
On the day, we arrive 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 before work begins, and floors and nearby surfaces are sheeted. The work itself takes an hour or two for one fan, longer when it’s hard to reach. For a job in Headstone, tell us about loading bays, permits, lifts and roof access when you book.
- We find the fan and check how it’s reached and how it’s isolated.
- The fan is isolated so it can’t start while we work.
- The impeller and the housing around it are scraped clean.
- Blades, housing and the area around the motor are degreased with care.
- It’s closed up, run and checked, and photos go into your report.
Getting ready for the visit
- Move anything stored near the system
- Let us know how we reach the system, including roofs, risers and plant rooms
- Have your last certificate or report to hand

Related advice
How the job changes from site to site
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.
Fan housings and motors
The housing around the impeller catches grease flung off the blades. It’s scraped and degreased with the impeller.
In-house cleaning or a specialist?
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.

FAQs for Headstone
Can school kitchens in Headstone be cleaned in the holidays?
Yes, holiday work suits schools best. There are about 5 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Headstone. Just ring 0345 646 2711, or email photos with your term dates and we’ll plan around them.
Can parking be tricky for a job in Headstone?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. Where restrictions apply in the day, an evening or overnight visit usually gets round them.
Where does the waste go?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. We don’t leave it behind.
How far ahead should we book?
For planned work, earlier is better, especially if the next clean or test is due soon. Emergencies are different, because our line is open 24/7.
Do we lose a day’s trading?
Not usually. Booking the work out of hours means the site can carry on as normal. Larger jobs can be phased over several visits to keep things running.
Do you work with multi-site operators?
Yes. One number covers all your sites across London and the South East, with visits on a regular schedule.
How do you protect the area?
We start with protection: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.
Do you need to turn the fan off to clean it?
The fan must be isolated, for safety. Cleans are done when the kitchen is closed, so cooking isn’t affected.
What a clean will not put right
We’d rather tell you now than book work that will not help, so here are the limits:
- Grease in the canopy and ductwork
- An undersized fan that cannot cope
- Wiring faults to the fan
Not sure which it is? You can call 0345 646 2711 or use the quote form and we will tell you honestly before booking.
What the work covers
- Fan housings
- In-line fans
- Centrifugal fans
- Discharge points
- Axial fans
- Roof-mounted fans
When to call us in Headstone
A fan collects more grease when the filters let more through. Missing, damaged or badly fitted filters let grease travel the whole system, so the fan takes far more than it should.
Look out for any of the following:
- Weak extraction at the canopy
- A fan left out of previous cleans
- A fan motor running hot under a coat of grease
- Burning smells from the fan area
Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Headstone is Northwood and Pinner Cottage Hospital, about 2.2 miles west.
