Extract fan repair for kitchens and businesses in Gunnersbury
Working on a fan in Gunnersbury means switching the extract off first, so the job is fitted around the kitchen’s hours. We can work in the evening, overnight or at the weekend and there’s a 24/7 emergency line if the fan fails while you’re cooking. The work covers roof and wall fans, belts and pulleys and fan housings, and the jobs we see most are an overheating extract motor and a fan running too slowly to clear the kitchen.
London extract fans often sit on rooftops, exposed to the weather as well as the grease, and in time, bearings, belts and motors fail. Noise and vibration are worth reporting before the fan stops.
We have 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 carry full insurance.

When to call us in Gunnersbury
Over the years, mountings loosen and rubber mounts break down. The fan’s movement then travels into the ductwork and structure and that is a common source of rattles.
The symptoms we are asked about most are:
- A squealing belt on start-up
- A humming noise from the fan motor
- A fan that will not start at all
- A fan shaking on its mountings
If you manage a school such as Strand-on-the-Green Junior School and the kitchen fan is getting louder, the next break is the time to deal with it.
What your quote should include

- Proof of accreditation you can verify

For landlords and multi-site operators
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. With shared responsibility, good records help everyone.
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’re happy to quote for all of it.
The process
The visit has three parts: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with pictures. The middle part takes longest, and that takes an hour or two to diagnose, then longer if parts or a new fan are needed. For a job in Gunnersbury, tell us about loading bays, permits, lifts and roof access when you book.
- You describe the fault and we arrange a visit.
- We isolate the fan before touching it.
- We diagnose the fault, checking the controls as well as the fan.
- A fixed quote for the repair or replacement follows.
- We fix the fault and run the fan to check it.
How to prepare
- Arrange a key holder or contact on site
- Tell us where we can park and unload
- Tell us the best time to work, such as after service or at a weekend
Getting a quote
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before we start.
Advice
Why deal with it now?
A noisy fan rarely fixes itself. Bearings that are left to wear can fail suddenly, and that often happens mid-service. A repair booked now is simpler than an emergency later. In a London building, a problem in a duct, damper or fan rarely stays in one unit.
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we’ll go through it with you.
Why choose Duct Doctor in Gunnersbury

Different parts, different methods
Roof and wall-mounted fans
Fans are often mounted on roofs or external walls. How easy the fan is to reach shapes the job, so we ask about it early.
Direct-drive fans
Direct-drive fans are compact and common in kitchen extracts. If the motor has gone, a replacement unit is often the sensible option and we’ll talk you through it.
Between visits
After the visit, a few habits help the work last:
- Make sure the isolator and controls are easy to reach
- Never run the extract with filters missing
- Don’t wait for a noisy fan to stop
- Note when the fan trips or cuts out
Clean filters help a repaired fan stay that way. The less grease that reaches the fan, the longer its parts last and fewer faults.
A 3, 6 or 12-monthly cleaning plan brings us back at set intervals, so the fan is looked at as part of each visit and problems are spotted sooner.
Common questions in Gunnersbury
Do you work at weekends in Gunnersbury?
Yes, we can come after you close and finish before you open. The work in Gunnersbury can fit around your hours. Just call 0345 646 2711, or email photos with your opening times and we will plan around them.
Does London parking affect a job in Gunnersbury?
Tell us where a van can stop near your site in Gunnersbury, and about any building rules on loading. Night visits tend to make loading easier on London streets.
Do we need to close while you work?
Not typically. We work when the area is out of use, such as evenings, overnight, early mornings or weekends, so the site can carry on as normal.
Will I get paperwork for my records?
Yes. Each visit ends with a written report and photos, showing what was done, anything we couldn’t reach and when the next visit is due. Kitchen extract cleans to TR19® Grease also get a certificate through the BESCA Vent Hygiene Elite portal.
Can one contract cover all our sites?
Yes. Send the list of sites and the work at each and you’ll get one fixed quote.
How long does an extract fan repair take?
It depends on the fault, but as a guide it takes an hour or two to diagnose, then longer if parts or a new fan are needed. You’ll know more once we have found the fault.
Do you replace extract fans as well as repair them?
Yes, when repair does not make sense. The replacement has to suit the ductwork and the cooking before recommending a unit.
What should go in our maintenance log?
Everything that shows the system is looked after: our reports and photos, any certificates and your in-house logs. One maintenance log per site keeps it simple.

Extract fan repair around Gunnersbury
The FSA’s food hygiene register shows about 333 restaurants, cafés and canteens and about 105 takeaways across Gunnersbury and its immediate surroundings (about a mile and a half). Wherever they cook under a canopy, a failed extract fan stops the kitchen. It’s Hounslow council that sends environmental health officers to food businesses in Gunnersbury. Under food hygiene rules, a kitchen needs suitable and sufficient ventilation. That makes a fan repair urgent rather than something to put off. A failed fan in a London kitchen normally means a closed kitchen, so access details help us plan the repair.
Hall kitchens near St Michael's Church, or anywhere around Gunnersbury, often use their fans only now and then, and an idle fan can stick. For a takeaway near Gunnersbury station, a fan that fails on a busy evening means turning customers away, and our emergency line runs 24/7.
