About our extract fan cleaning in Ash Green
Duct Doctor has been cleaning kitchen extract fans since 2009. As a BESCA Vent Hygiene Elite member, we clean to BESA TR19® Grease, with CHAS, SafeContractor and ISO 9001 and full insurance. If you are dealing with burning smells from the fan area and a fan coated in grease inside its housing, we can help.
Work in a small place like Ash Green 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.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Your questions about extract fan cleaning in Ash Green
Can you clean school kitchen extracts in Ash Green during the holidays?
Yes, and it’s the easiest time to do it. The FSA’s register shows about 12 schools and colleges with food registrations within roughly a mile and a half of Ash Green. Booking early in the term gives the best choice of holiday dates.
Will you come out to Ash Green?
Yes, we work in villages as well as towns, and Ash Green is covered. Photos of the system and directions to the site help us plan the visit.
Will we have to shut during the visit?
Not normally. The area we’re working in has to be out of use while we are there, so we book a time when it would be closed anyway.
Do you look at the system first?
Yes. Every job is surveyed first, either from photos and details you send or on a site visit. A fixed quote follows.
Who has the legal duty for fire safety?
Under the Regulatory Reform (Fire Safety) Order 2005, it’s the responsible person: often the employer, owner or occupier. Landlords, facilities managers and managing agents can also hold responsibility.
Are you insured?
Yes. We are fully insured, and the details are available on request.
Can you look after several sites?
Yes. Tell us the addresses and what each needs and you will get one fixed quote.
Which sectors do you work in?
All kinds of commercial and public premises: kitchens, offices, schools, healthcare, retail, leisure and food production. Work is timed around how each site runs.
What your team can do, and what needs us
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That’s our job.
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.

What we do, step by step
Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. The visit takes a few hours where there are several fans or heavy deposits. The timing of a visit to Ash Green is set by you, and the travel is our side of the planning.
- First we check the fan’s condition and how it sounds.
- With the fan isolated, the housing is opened.
- The impeller is cleaned blade by blade so it runs balanced.
- Housing, outlet and the area around the motor are cleaned.
- The fan goes back into service with a report on its condition.
Before we arrive
- Move anything stored near the system
- Mention any parking or loading restrictions
- Let us know when the site is closed or quiet

Here’s what helps us quote: the address, the type of site and when it’s open, photos of the system and the last certificate or report, if there is one. Then phone us on 0345 646 2711 or email us.

What the work involves, part by part
Roof-mounted fans
Grease can escape from a roof fan onto the surrounding surface, so the outlet area is checked too. We note any grease around the fan.
Impellers and blades
The impeller is the spinning part that moves the air, and grease builds up on them unevenly. That is what unbalances the fan, so it’s cleaned carefully blade by blade.
Kitchen extracts in Ash Green
There are about 8 restaurants, cafés and canteens and about 8 takeaways and sandwich shops in Ash Green and the streets around it, up to about 1.5 miles out, according to the Food Standards Agency’s register. The fan at the end of each of those extracts collects grease that slows it and wears the motor. Food hygiene inspections in Ash Green are the job of Guildford council’s environmental health team. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Keeping each certificate and photo report on file helps show the extract is looked after. Fire safety in Ash Green falls to Surrey 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.
Where a hall near Church of St Peter, or anywhere in Ash Green, hosts lunch clubs or events, its extract gathers grease just as a café’s does. If you run catering at a healthcare site, such as a hospital like Guildford Hospital about 4.2 miles east, the extract may need cleaning more often than a part-time kitchen.
Ash Green is about 2 miles east of Aldershot, in Surrey. Whether your site is in the middle of Ash Green or further out, extract fan cleaning is available to all kinds of commercial premises, from small sites to large estates. Ash Green is one of 395 towns, villages and districts in Surrey where we work for extract fan cleaning. Guildford is in our area too, around 6 miles away.
Work in GU12 is surveyed, quoted and booked the same way as anywhere else. We cover sites on Compass Rose Road, Drovers Way and Ash Green Lane East and nearby roads. Neighbouring places we cover for extract fan cleaning include Ash (1 mile west), Tongham (1 mile south-west), Seale (1 mile south), Ash Vale (2 miles north-west) and Sandy Cross (2 miles south-west). We also work in nearby towns such as Guildford (6 miles east), Woking (8 miles north-east), Camberley (6 miles north), Farnham (4 miles south-west), Egham (15 miles north-east) and Frimley (5 miles north).
Local landmarks in Ash Green
Around Ash Green, our work takes us to kitchens and buildings near The Dover Arms, The Connaught School and Ash Manor School. For rail, the closest station is Ash station, roughly 0.6 miles north-west of the centre. A little further out are Farnham Castle (4.4 miles west) and Guildford Hospital (4.2 miles east). The countryside around Ash Green includes Ash Ranges and Hog's Back.
Keeping the system healthy
So the system stays in good health:
- Look for grease stains near the discharge
- Run the extract throughout cooking
- Never cook with a filter missing
- Listen for new noises or vibration from the fan
We take away the grease and dirty water from the fan clean. Wherever the fan is, the area around it is cleaned down.
Keep the whole system on its cleaning cycle. A fan cleaned with the rest of the system on time rarely gets badly coated, in line with BESA guidance.
What a clean won’t put right
In fairness, there are a few things this work will not fix:
- Damaged fan blades
- A motor that has burnt out
- Wiring faults to the fan
If in doubt, call us on 0345 646 2711 or send us an email and we will say what we think before you book.
What the work covers
- Roof-mounted fans
- Fan housings
- Discharge points
- Axial fans
- In-line fans
- Centrifugal fans
What happens if it’s left?
A greasy fan at the discharge can spread grease onto the roof or wall around it. That stains surfaces and can add to the fire risk outside the building, which is one more reason to keep it clean. A fault that closes a site in a village like Ash Green affects everyone who depends on it.
Working hours, access and the scale of the site can all change the price. Each of those is built into the quote and give you a fixed price before any work starts.

Do you need extract fan cleaning in Ash Green?
A greasy fan in Ash Green is fuel at the end of the duct. A fire in the duct can reach the fan and the grease around it, and a hot, struggling motor does not help.
If you notice any of these, it’s worth a diagnosis:
- Vibration from an unbalanced impeller
- Weak extraction at the canopy
- Burning smells from the fan area
- A fan left out of previous cleans
Commuter trade near Ash station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands.
