Extract fan repair and replacement in Cumnor, Oxfordshire
Our technicians work in Cumnor on extract fan repair and replacement. Out-of-hours visits, a fixed quote and a written report with pictures as standard.
- A squealing belt on start-up
- A whining or grinding extract motor
- An extract that vibrates through the ductwork
What the work involves, part by part
Belt-driven fans
Belt-driven fans have a motor that turns the impeller through belts and pulleys. Worn belts squeal and slow the fan down, and pulleys and bearings need checking too.
Impellers and housings
The impeller does the work of moving air through the system. Grease on it throws it out of balance and make it shake.
Extract fan repair in Cumnor
Before anything is ordered, we diagnose. The motor, drive, impeller, bearings and mounts are all checked and the speed control too. Then you’re given a fixed quote for the repair or the replacement. The work covers bearings, belts and pulleys and roof and wall fans, and common reasons people get in touch are a worn or slipping fan belt and vibration spreading from the fan into the ducts.
A callout to a small place like Cumnor goes better when we know what we’re looking at: photos of the fan, its rating plate and how to reach it all help.
The report is your system’s health record: dated, with photos, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

When to call us in Cumnor
Kitchen extract fans in Cumnor face the same conditions as anywhere else: heat, grease, steam and long running hours. Condensation can corrode parts, and age catches up with every fan in the end.
If you notice any of these, it’s worth a diagnosis:
- An extract fan that has stopped working
- A fan shaking on its mountings
- Weak extraction and a smoky kitchen
- A belt-driven fan that squeals
Occasional-use kitchens, such as a hall kitchen near Church of St Michael or elsewhere in Cumnor, are where a stiff or seized fan can turn up.
Before booking anyone
- Exactly which parts of the system are covered
- Whether they’re fully insured
- Whether the quote shows VAT
- When they can work, and whether that is outside your opening hours

The process
The first job on site is protection: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. It takes part of a day for most faults, with a return visit if parts have to be ordered, and the area is cleaned down before we leave. Pictures of the system and its access let us plan the work in Cumnor before we set off.
- First, you tell us the symptoms: noise, shaking, weak extraction or no power.
- With the fan safely isolated, we open it up for a proper look.
- Each part is checked in turn: motor, bearings, drive, impeller and fixings.
- You hear what’s wrong and what it will cost, with a fixed quote, before we go ahead.
- We fix or replace the fan, then test it running before we leave.
Getting ready for the visit
- Mention any locked doors, roof access or ceiling voids
- Have your last certificate or report to hand
- Let us know about permits to work or site inductions
Getting a quote
Some systems can be priced from pictures; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before any work starts.
Advice
Cumnor: your questions answered
Can the work in Cumnor be done at night or at weekends?
Yes, nights and weekends are routine for us. That way a site in Cumnor doesn’t have to lose a day’s trading. Just give us a ring on 0345 646 2711 or send us an email with your opening times and we’ll plan around them.
Is Cumnor within the area you cover?
Yes. Villages and rural sites across the South East are part of our work, Cumnor included. Let us know about access, parking and anything unusual about getting there when you book.
Can you supply and fit a replacement fan?
Yes. If repair is not sensible, we replace the fan. The replacement has to suit the ductwork and the cooking before recommending a unit.
Will we have to shut during the visit?
Not usually. We need the work area to ourselves while we are on site, so we book a time when it would be closed anyway.
How much time does a fan repair need?
It depends on the fault, but as a guide it takes part of a day for most faults, with a return visit if parts have to be ordered. You’ll know more once we have found the fault.
What will a fan repair or replacement cost?
The cost depends on what’s wrong and how easy the fan is to reach. After diagnosing, you get a fixed quote so there are no surprises.
Which records should we keep?
Anything that proves the system is maintained: our reports and pictures, any certificates and your in-house logs. One maintenance log per site keeps it simple.
Does a faulty extract fan always need replacing?
In many cases, yes. Many faults are fixed by cleaning the impeller or renewing worn parts and we only recommend replacement when repair does not make sense.
Landlords, agents and facilities managers
We also work for facilities teams across offices, schools and healthcare across Oxfordshire. Larger estates can be phased building by building around the people who use them.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.

When it’s something else
We won’t sell you work that doesn’t address the problem, so here are the limits:
- Gas interlock faults that a Gas Safe registered engineer must deal with
- Problems with the electrical supply to the fan (an electrician’s job)
- Cooking smells reaching neighbours, which may need odour control
If in doubt, give us a ring on 0345 646 2711 or drop us a line and we’ll say what we think before booking.
Parts of the system we cover
- Bearings
- Roof and wall fans
- Belts and pulleys
- Kitchen extract fans
- Fan housings
- Fan motors
Leave it or put it right?
Where the cooking gas supply is interlocked with the extract, a failed fan can stop the kitchen cooking. Without extraction, the heat and fumes build up fast, so a failing fan is worth dealing with early. Equipment tucked in a roof space or outbuilding near Cumnor rarely gets looked at unless someone books it.
Combining work into one visit or one programme often makes better use of the time. Mention every system or site you need covered, and you will get one fixed quote.

Keeping the system healthy
Aftercare is simple, and it makes the next visit easier:
- Note when the fan trips or cuts out
- Keep access to the fan controls unobstructed
- Keep all filters fitted while cooking
- Don’t turn the fan down to hide a noise
If parts have to be ordered, we tell you how the kitchen can carry on in the meantime. The fan is completed on a return visit outside your busiest hours.
When filters block, the fan works harder. Keeping filters clean eases the strain and protects the motor.
