Extract fan repair for kitchens and businesses in Duncton
We treat a failing fan much like a patient: we hear the symptoms, find the cause and put it right. The aim is steady, quiet extraction and a plain account of what we found. If you’re dealing with a dead fan motor and a squealing belt on start-up, we can put it right.
For a fan repair in or near Duncton, the more you tell us about the fan, the better the first visit: photos of the fan, its rating plate and how to reach it all help.
We’ve been trading since 2009, as 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.

What affects the quote in Duncton
Some jobs are bigger than they look, and some smaller. The main factors:
- Where the site is and how we reach it
- The size of the system
- The condition of the system
- Any permits to work or inductions
A single site or a whole portfolio, the quote is built the same way: the work involved, the access and the timing. You will have a fixed price before we start.
What we need to know
To speed up the quote, send us:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Wide photos of the system and the area around it
- Your last certificate, test record or report
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
Here’s what helps us quote: where the site is, what it is and its opening hours, pictures of the system and the last certificate or report, if there is one. Once you have those, ring 0345 646 2711, or send details by email.
When a fan fails in Duncton
The FSA’s food hygiene register shows about 3 restaurants, cafés and canteens within 1.5 miles or so of the middle of Duncton. Every one of them that cooks under a canopy depends on its extract fan to keep cooking. We cover Duncton, about 45 miles from central London, as part of our work across London and the South East. A survey and a fixed quote come first, then the visit at a time that suits you. In Duncton, food businesses are inspected by environmental health officers from Chichester council. Under food hygiene rules, a kitchen needs suitable and sufficient ventilation. That’s one more reason not to keep cooking with a broken fan.
For school kitchens, at schools like Duncton CofE Junior School for example, a planned fan repair in the holidays avoids losing lunches in term time.

What happens on the day
There are three stages on the day: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and pictures. Most of the time goes on the work itself, and that takes part of a day for most faults, with a return visit if parts have to be ordered. If the van will struggle with a lane or gateway near Duncton, let us know and we’ll plan around it.
- We ask what the fan is doing, from noise and vibration to a full stop.
- With the fan safely isolated, we open it up for a proper look.
- We check the motor, bearings, drive, impeller and mountings.
- You get our diagnosis and a fixed quote to repair or replace.
- The repair or replacement is carried out and the fan is run and checked.
How to prepare
- Find the previous report, if there is one
- Make sure someone can let us in and lock up afterwards
- Let us know how we reach the system, including roofs, risers and plant rooms

Related advice
Different parts, different methods
Motors and bearings
The motor and its bearings work hardest. Hot, greasy air and long days wear them down.
Roof and wall-mounted fans
Fans outside are exposed to rain and condensation. Rust on fixings and housings is a frequent find.
Why it’s worth doing now in Duncton
An overloaded motor is under constant strain. Every hour of strain takes its toll, and when it finally fails, it may take other parts with it. Catching it early keeps the repair small. It’s worth booking a check, because nobody sees inside a duct day to day.
Putting the work off seldom saves money. Problems in a system tend to grow, which can make the next visit longer. If you are unsure, call 0345 646 2711 or use the quote form and we will give you an honest view and a fixed quote.

Keeping the system healthy
No system stays clean for ever, but care slows the build-up. Our tips:
- Clean or change filters on schedule
- Keep the fan on a planned cleaning cycle
- Avoid lowering the speed to quieten a fault
- Keep access to the fan controls unobstructed
Listen to the fan over the next few weeks. A new noise or vibration is worth reporting early rather than waiting for it to fail.
A fan that is starting to make noise is giving you a warning. Booking a check at this stage keeps it a planned job rather than an emergency during service.
Signs you need extract fan repair in Duncton
Not every problem is mechanical. A failed speed controller or a wiring fault can stop a fan, and a fan that won’t start is not always a dead motor.
If you notice any of these, it’s worth a diagnosis:
- A motor that trips out or overheats
- An extract fan that rattles or knocks
- A fan shaking on its mountings
- A humming noise from the fan motor
If you look after a church or hall kitchen near Church of Holy Trinity, or anywhere in Duncton, test the extract fan before a big event rather than on the day.
Questions to ask before booking
- If the quote is a fixed price or an estimate
- How areas they can’t reach will be recorded
- Whether the quote shows VAT
- What records you’ll receive afterwards

What else we do in Duncton
Duncton: your questions answered
Can you come to Duncton after we close?
Yes, we can come after you close and finish before you open. It means the site in Duncton keeps running as normal. Tell us your opening hours when you ask for a quote.
Which environmental health team covers Duncton?
The local authority for Duncton is Chichester council, and its environmental health team does the inspecting. An officer may ask how the kitchen is ventilated, so keep repair records with your maintenance file.
Do we need to close while you work?
Not normally. Visits are timed for when the area is closed, such as overnight or at a weekend, so you keep your normal hours.
Which kinds of sites do you work on?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, as well as food production and leisure sites.
Why is our extract fan so noisy?
It can be one of a few things, including bearings, belts, grease and mounts. It’s worth having it diagnosed before the fault gets worse.
Do you replace extract fans as well as repair them?
Yes, when repair doesn’t make sense. We check the duct size and the extract the kitchen needs before recommending a unit.
How much time does a fan repair need?
That depends on what’s wrong, but most jobs take anything from an hour or two to a full visit, depending on the fault. We will give you a better idea once we have diagnosed it.
Will you tell us when the next visit is due?
Yes. We put a recommended next date on the report. BESA’s minimum intervals for kitchen extracts range from 3-monthly for heavy use to 12-monthly for light use, and fire dampers need testing at least once a year.
What extract fan repair cannot fix
We’ll always give you a straight diagnosis, so here’s what extract fan repair will not do:
- Cooking smells reaching neighbours, which may need odour control
- An extract system that was undersized from the start
- Wiring and supply faults beyond the fan itself
If you’re not sure, just phone us on 0345 646 2711 or email us and we will give you a straight answer.
