Extract fan cleaning in Dormers Wells
Every kitchen extract depends on its fan: it draws the air through the canopy and ductwork and pushes it outside. Grease that gets past everything else ends up on its blades and housing, and that is what we clean. The work covers centrifugal fans, fan housings and in-line fans, and the jobs we see most are an extract fan that vibrates or rattles and less air being pulled from the kitchen.
In London, few kitchens can spare a day to close, so work in Dormers Wells is normally booked for the night or the early hours. Parking, loading and access to the roof are agreed with the building before the night of the clean.
Duct Doctor has been trading since 2009, and we’re 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.

Dormers Wells questions
Can you work in Dormers Wells outside opening hours?
Yes, out-of-hours work is a big part of what we do. The work in Dormers Wells can fit around your hours. When you phone us on 0345 646 2711 or send us an email, mention when the site is quiet.
Can school kitchens in Dormers Wells be cleaned in the holidays?
Yes, out-of-term visits are normal for schools. Food Standards Agency records list about 45 schools, colleges and universities with registered kitchens within about a mile and a half of Dormers Wells. Tell us your holiday dates and we will book the visit for when the site is empty.
Do you provide a report after cleaning the fan?
A photo report, including the fan’s condition and the next clean date. File it with your other extract records.
Which sectors do you work in?
All kinds of commercial and public premises: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. Work is timed around how each site runs.
Should the extract fan be cleaned as part of TR19?
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.
What do you need from me for a quote?
A short description and a few pictures, with the address and opening hours. If we need more, we’ll ask.
Do you work with multi-site operators?
Yes. You deal with one contact for every site across London and the South East, and visits can be set on a regular cycle.
Is TR19 a legal requirement?
No, not in itself. TR19® is the benchmark insurers, fire officers and EHOs check against, and many insurers ask for proof of cleaning to it. The legal duty sits in the Regulatory Reform (Fire Safety) Order 2005 in England and Wales.

Why it’s worth doing now in Dormers Wells
The fan is part of the fire path. TR19® Grease covers the whole extract, fan included and many insurers require the full system to be cleaned to TR19. In a London building, a problem in a duct, damper or fan rarely stays in one unit.
Working hours, access and the scale of the site all affect the cost. We take each of them into account, and the price is fixed before we start.

What happens on the day
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool before we start, and floors and nearby surfaces are sheeted. The work itself takes an hour or two for most single fans. We fit London jobs around the building rather than the other way round, so a visit in Dormers Wells is typically out of hours.
- Diagnosis first: we look for grease, noise and vibration.
- Once isolated, we open the fan up.
- Each blade is cleaned so the impeller runs evenly.
- We clean the casing, the outlet and around the motor.
- The fan goes back into service with a report on its condition.
Before we arrive
- Clear the space around the work
- Allow time for equipment near the work to be turned off and cool down
- Arrange a key holder or contact on site
How to get a quote
To help us quote: the address, the type of site and when it’s open, pictures of the system and the last certificate or report, if there is one. Once you have those, call us on 0345 646 2711 or use the quote form.

Looking after it afterwards
After the visit, a few habits help the work last:
- Keep each photo report with the maintenance log
- Keep access to the fan clear
- Keep the fan on whenever the range is lit
- Look for grease stains near the discharge
We take away the grease and dirty water from the fan clean. Wherever the fan is, the area around it is cleaned down.
A change in how the fan sounds is worth noting. Rattles, hums or shaking can be early signs of build-up or wear and early action can save a repair.
Staff cleaning versus specialist work
In-house cleaning and specialist cleaning do different jobs. 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.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
When something else is needed
It’s worth knowing the limits before booking:
- A motor that has burnt out
- A cracked or broken impeller (it needs replacing)
- A fan that was never right for the kitchen
If in doubt, phone us on 0345 646 2711, or email photos and we’ll say what we think.
