Extract fan repair in Chalfont Common, done properly
Every fan job begins with finding the fault. Noise can come from grease on the impeller, worn bearings or a slipping belt; a dead fan can point to the motor or its controls. You hear what we’ve found before any work goes ahead. We’re often asked to deal with a fan rattling in its housing and vibration spreading from the fan into the ducts, on bearings, fan motors and fan housings.
Rural kitchens often have fans mounted on outside walls or roofs, exposed to the weather. That, with the grease, is hard on motors and bearings.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

FAQs for Chalfont Common
Do you work overnight in Chalfont Common?
Yes. We work evenings, overnight and at weekends. That way a site in Chalfont Common does not have to lose a day’s trading. Your opening times are the first thing we ask for.
Do you cover Chalfont Common for emergency fan repairs?
Chalfont Common is covered, and our emergency callout runs 24/7. The number to ring is 0345 646 2711. Details of the make and model help us plan the repair.
What’s TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.
Can you tell me the price of a fan repair?
We price each job after finding the cause. A belt and a new fan are very different jobs so the first step is a diagnosis.
What about areas you can’t get to?
We never leave them off the paperwork. The report says which parts couldn’t be reached and why, along with a quote to put access in.
What happens to the waste?
Anything we remove is contained as we work and taken away with us, including grease, debris and dirty water. None of it is left on site.
Who is the responsible person?
Under the Regulatory Reform (Fire Safety) Order 2005, it’s the responsible person: normally the employer or whoever controls the premises. Landlords, facilities managers and managing agents can also hold responsibility.
Can you look after several sites?
Yes. Tell us the addresses and what each needs and we will quote them together.
What happens on the day
A visit follows the same order every time: protect the area, make the system safe, do the work, clear away and leave you the report. The visit itself takes part of a day for most faults, with a return visit if parts have to be ordered. If you can send pictures, we can arrive in Chalfont Common knowing what to expect.
- You describe the fault and we arrange a visit.
- We isolate the fan before touching it.
- The fan and its controls are checked to pin down the fault.
- You get a fixed price for putting it right.
- The work is done and the fan is tested running.
Preparing for the visit
- Clear loose items from the work area
- Mention any locked doors, roof access or ceiling voids
- Name a contact who can let us in at the agreed time

Related advice
Between visits
Results last longer with the right care. We suggest:
- Do not wait for a noisy fan to stop
- Make sure the fan is cleaned with the rest of the system
- Keep all filters fitted while cooking
- Keep access to the fan controls unobstructed
Once we’re done, the extract is back in service. We clear up after ourselves and talk you through what we found.
A fan that’s starting to make noise is giving you a warning. Booking a check at this stage keeps it a planned job instead of a breakdown at the worst moment.
When something else is needed
A few issues sit outside what this work can do:
- Ductwork designed too small for the kitchen’s cooking
- Smells from the discharge that need odour control equipment
- Wiring and supply faults beyond the fan itself
If you are not sure, just phone us on 0345 646 2711 or send us an email and we will give you a straight answer before you book.
Parts of the system we cover
- Fan housings
- Kitchen extract fans
- Fan motors
- Belts and pulleys
- Bearings
- Roof and wall fans
Different parts, different methods
Motors and bearings
The motor and its bearings work hardest. Hot, greasy air and long days wear them down.
Fan controls
Supply faults are a job for an electrician. If that is the cause, we’ll say so and explain what we found.

When to call us in Chalfont Common
When filters clog and ducts fill with grease, the fan has to strain. A motor that strains runs hot, trips out or eventually burns out.
The symptoms we’re asked about most are:
- An overheating extract motor
- An extract that vibrates through the ductwork
- Poor airflow at the canopy
- A fan worn beyond sensible repair
A fan that rarely runs, like one in a hall kitchen near St Paul's or elsewhere in Chalfont Common, can seize between uses.

We work for landlords, managing agents and facilities managers as well as the people running the site. 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.
Why deal with it now?
A struggling motor runs hotter and works harder. That shortens its life, and when it finally fails, it may take other parts with it. Early attention keeps the cost and disruption down. Rural sites can’t always move to another kitchen or room when something fails.
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we’ll go through it with you.
