West Dulwich extract fan repair
Repair and replacement of kitchen extract fans, fan motors and worn fan parts in West Dulwich, surveyed first and signed off with a written report and pictures. Call for a fixed quote.
- A humming noise from the fan motor
- Weak extraction and a smoky kitchen
- A fan that keeps cutting out
What the work involves, part by part
Roof and wall-mounted fans
Fans are often mounted on roofs or external walls. Access affects how long a repair takes and we plan around it.
Motors and bearings
If the motor runs hot or keeps tripping, something’s wrong. The cause might be grease restricting the airflow or the motor may be near the end of its life.
About our extract fan repair in West Dulwich
Working on a fan in West Dulwich 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. If you are dealing with an old fan that needs replacing and a belt-driven fan that squeals, we can help.
Replacing a fan in a London building often means working at height or in a tight plant space, and in West Dulwich, parking and lifting are part of that. Work can be done after service, so the kitchen loses as little time as possible.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

When something else is needed
An honest diagnosis matters more to us than a booking, so here’s what extract fan repair will not do:
- Grease build-up in the rest of the extract system
- Wiring and supply faults beyond the fan itself
- Cooking smells reaching neighbours, which may need odour control
If in doubt, give us a ring on 0345 646 2711, or email photos and we’ll say what we think.

- Belts and pulleys
- Fan housings

In-house cleaning or a specialist?
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Keeping the system healthy
Here’s the after-treatment advice, in brief:
- Tell us about a new rattle or whine right away
- Make sure every filter is in place and clean
- Keep the fan on a planned cleaning cycle
- Keep the area around the fan controls clear
Clean filters help a repaired fan stay that way. The less grease that reaches the fan, the longer its parts last and the quieter it runs.
Small faults, like a worn belt, are quick to fix. Left for months, they can damage the motor or bearings, so it’s worth acting early.
What we do, step by step
Each visit runs to the same pattern: protect the area, isolate whatever needs isolating, carry out the extract fan repair, tidy up and hand over the paperwork. The visit itself takes an hour or two to diagnose, then longer if parts or a new fan are needed. A name and number for whoever controls access to the building in West Dulwich saves time on the night.
- We agree a time to attend, out of hours if needed.
- The extract is switched off and the fan opened up.
- Bearings, drive, impeller, motor and mounts are inspected.
- You hear whether repair or replacement makes sense, with a fixed quote.
- The fan is repaired or replaced, then checked running.
Getting ready for the visit
- Find the previous report, if there is one
- Let us know about permits to work or site inductions
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
Ask for a quote
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and we can price many jobs without a visit.

Your questions about extract fan repair in West Dulwich
Who inspects food businesses in West Dulwich?
That is Lambeth council, whose environmental health officers carry out food hygiene inspections in West Dulwich. Keeping the fan serviced is easier than explaining a broken one on inspection day.
Does London parking affect a job in West Dulwich?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Where restrictions apply in the day, an evening or overnight visit typically gets round them.
Who do we call if the fan stops in the middle of cooking?
There’s a 24/7 emergency and out-of-hours callout. Just call 0345 646 2711 or drop us a line at any time if the extract stops and we will arrange a visit.
How much does an extract fan repair cost?
The price depends on the diagnosis. Once we’ve looked at it, you get a fixed quote for whichever option you choose.
What should go in our maintenance log?
Every certificate and report from each visit, kept together in your maintenance log with your in-house cleaning records. BESA says certificates should show the date, location and technician.
Do you provide a certificate or report?
Yes, always. The report is dated and includes photos, plus a certificate via the BESCA Vent Hygiene Elite portal for TR19® Grease cleans. File it with your fire safety records.
What types of premises do you cover?
Commercial premises of every kind: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. Work is timed around how each site runs.
What makes a kitchen extract fan rattle or whine?
Noise typically comes from grease build-up, bearings, belts or loose fixings. Rattles, whines and grinding point to different faults, and we diagnose it on site.
What extract fan repair looks like in West Dulwich
There are about 227 restaurants, cafés and canteens and about 125 takeaways and sandwich shops within roughly a mile and a half of the centre of West Dulwich, according to the Food Standards Agency’s register. A kitchen with a dead extract fan gets hot and smoky fast, and kitchens like these feel it at once. A failed fan in a London kitchen usually means a closed kitchen, so access details help us plan the repair. Food hygiene inspections in West Dulwich are the job of Lambeth council’s environmental health team. Food hygiene rules expect food premises to have suitable and sufficient ventilation. Getting the fan running again is the priority.
For school kitchens, at schools like Dulwich Wood Primary School for example, a planned fan repair in the holidays avoids losing lunches in term time. If you run a church or community hall kitchen, near Church of St Stephen or elsewhere in West Dulwich, an extract fan that rarely runs can seize or fail when it’s needed. For kitchens close to Sydenham Hill station, a fan that stops mid-service needs fixing fast, and our emergency line runs 24/7.

Landlords, agents and facilities managers
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We’re happy to deal with either side, and the report can go to both.
We also work for facilities teams across offices, schools and healthcare across Greater London. Larger estates can be phased building by building to keep disruption down.
What affects the cost of extract fan repair
A fixed price needs a few facts first. We look at:
- Where the site is and how we reach it
- Whether several sites go on one quote
- Whether we need access equipment or extra panels
- The condition of the system
What you pay depends on how big the system is, what state it’s in and how easy it is to reach. You get a fixed price before work begins, so there are no surprises.
What to send for a quote
Photos and a few facts are often enough to price the work. Send what you can of the following:
- The postcode and the type of business
- Problems your staff have spotted
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Your opening hours and when the area is out of use
We don’t publish a price list, because no two systems are the same. Instead, we look at your site first, from photos or a survey, and then send you a fixed quote. To get going, call us on 0345 646 2711 or send us an email.
