Extract Fan Cleaning in Isington
One call covers cleaning of kitchen extract fans, impellers, fan housings and discharge points in Isington: survey, fixed quote, work and sign-off. CHAS and SafeContractor accredited, ISO 9001 and fully insured.
- Less air being pulled from the kitchen
- A fan coated in grease inside its housing
- An extract fan that vibrates or rattles
Different parts, different methods
Roof-mounted fans
On a roof, the air is cooler and grease drops out faster. We scrape and degrease the blades and casing.
Inline duct fans
Space around an inline fan can be tight, so we plan how to reach and clean them. Anything out of reach is recorded.
Extract fan cleaning in Isington, done properly
The extract fan is the heart of the system: it pulls air from the canopy, through the duct and out of the building. Whatever grease slips past the filters and duct reaches the fan, and that’s what we clean. Typical jobs include weak extraction at the canopy and a motor area thick with grease, across in-line fans, fan housings and roof-mounted fans.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, and those horizontal sections are where grease settles. We agree access and timings in advance.
Duct Doctor has been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.

In-house cleaning or a specialist?
Staff cleaning and specialist work aren’t the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
When to call us in Isington
A fan in Isington builds up grease at a rate set by the kitchen, not the location: how many hours a day the kitchen runs and what it cooks. BESA guidance sets minimum intervals of 3, 6 or 12 months for the whole system by daily use.
These are the problems we see most often:
- A fan that no longer moves enough air
- A heavily greased fan housing
- A motor area thick with grease
- An extract fan with no cleaning record
For schools such as Binsted Church of England Primary School, kitchen extract cleaning is normally booked for the holidays, when the canteen is closed.
Questions to ask before booking
- How VAT is shown on the quote
- What happens if part of the system cannot be accessed
- What hours they’ll be on site
- If the quote is a fixed price or an estimate
Managing agents and facilities teams in Isington
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
Facilities teams in offices, schools and healthcare sites book us too across Hampshire. Larger estates can be phased building by building around the people who use them.
Questions from Isington
Which environmental health team covers Isington?
In Isington, it’s East Hampshire council that carries out food hygiene inspections. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
Can the work in Isington be done at night or at weekends?
Yes, we can come after you close and finish before you open. That way a site in Isington does not have to lose a day’s trading. Just give us a ring on 0345 646 2711, or email photos with your opening times and we will plan around them.
What should I send you?
Where the site is, what it is and when it’s open, plus photos of the system and your last certificate or report if you have one.
Will we have to shut during the visit?
Not typically. Booking the work out of hours means the site can carry on as normal. Larger jobs can be phased over several visits so parts stay in use.
What’s the cleaning interval for an extract fan?
It’s cleaned with the whole extract, from every 3 months for 12 to 16 hours of cooking a day to every 12 months for 2 to 6 hours. Grease readings and the fan’s condition can show it needs more.
Can you fix a fan that is worn out?
Fan repair and replacement is part of what we do. If cleaning shows a worn motor, bearings or impeller, we will tell you and quote for the repair.
Why has my extract fan got louder?
A common cause is grease. Uneven build-up on the blades throws the fan off balance, causing vibration and noise. Cleaning may sort it, but worn bearings or a failing motor need a repair.
Does a TR19 kitchen extract clean cover the fan?
Yes, it should be. A TR19 Grease clean covers everything from canopy to discharge, and the fan is a key part of it, so it’s cleaned too.
Leave it or put it right?
Vibration from an unbalanced impeller does not stay small. It can wear the bearings and lead to failure, which may leave the kitchen without extraction. A planned clean beats an emergency. Out of sight is the usual reason a rural system goes too long without attention.
The cost depends on how big the system is, the condition it’s in and how easy it is to reach. We give you a fixed price before work begins, so there are no surprises.
Why book with us
- Fully insured
- Photo reports with every job
- We diagnose before we treat
- CHAS and SafeContractor accredited, with ISO 9001
How it works
On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool first, and floors and nearby surfaces are sheeted. The work itself takes a couple of hours per fan, depending on its size and the build-up. Rural roads and tight entrances are worth telling us about before a visit to Isington.
- First we locate the fan and agree how it’s safely isolated.
- The fan is isolated so it cannot start while we work.
- We remove the grease from the blades, impeller and casing.
- The fan and its surrounds are degreased, keeping clear of the motor’s electrics.
- We reassemble, run the fan and photograph the result.
How to prepare
- Make sure someone can let us in and lock up afterwards
- Tell us where we can park and unload
- Allow time for equipment near the work to be turned off and cool down

Getting a quote does not take long. Send a few details and pictures, and we usually reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.

What a clean will not put right
We’d rather tell you now than book work that won’t help, so here are the limits:
- Grease in the duct and canopy before the fan (those need a full TR19 clean)
- Electrical faults in the fan’s supply or controls (an electrician’s job)
- An undersized fan that cannot cope
If in doubt, ring 0345 646 2711, or send details by email and we’ll say what we think before booking.
What we work on in Isington
- Roof-mounted fans

Grease, kitchens and Isington
Fire safety in Isington falls to Hampshire and Isle of Wight Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. Environmental health officers from East Hampshire council inspect food businesses in Isington. Extraction counts as kitchen equipment, so its condition can come up on the day. Our report lists what was cleaned and when, which is useful to have ready.
For kitchens close to Bentley (Hampshire) station, where the day often starts early and ends late, the extract can be cleaned overnight. Healthcare kitchens, like those at hospitals such as Chase Community Hospital (about 5 miles south), often cook for long hours, which puts them in BESA’s heavier-use bands.
