About our extract fan repair in Dulwich Village
Across Dulwich Village, we deal with fan faults of every kind, from a squeal at start-up to a fan that will not run at all. We find the cause, give you a fixed price and fix it or fit a replacement when it’s beyond repair. Typical jobs include a fan rattling in its housing and a fan running too slowly to clear the kitchen, on fan housings, belts and pulleys and kitchen extract fans.
Replacing a fan in a London building often means working at height or in a tight plant space, with parking and lifting to arrange in Dulwich Village. Repairs can be done out of hours so the kitchen keeps trading.
Duct Doctor has 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’re fully insured.

Landlords, agents and facilities managers
We also work for facilities teams across offices, schools and healthcare in Dulwich Village and across Greater London. Work can be phased by floor, building or site to keep disruption down.
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We can quote either party and send the paperwork to whoever needs it.
What affects the cost of extract fan repair
The price is fixed before any work begins. It takes into account:
- The number of sites or systems
- Any permits to work or inductions
- The times the site is available
- One-off work versus a regular cycle
What you pay reflects the actual work. That is why every job is surveyed first, and the price is agreed before work begins.
What to send for a quote
When you call or email, it’s useful to have:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Any previous report or certificate
- Any access panels or hatches you can see
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
We don’t publish a price list, because every site is different. Instead, we look at your site first, from pictures or a survey, then send a fixed quote. To get going, call 0345 646 2711 or use the quote form.
Keeping the system healthy
Simple habits between visits make a real difference. We recommend:
- Do not turn the fan down to hide a noise
- Do not wait for a noisy fan to stop
- Write down when the fan misbehaves
- Make sure every filter is in place and clean
Clean filters help a repaired fan stay that way. Less grease on the impeller means less wear 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 wear is caught earlier.
Different parts, different methods
Roof and wall-mounted fans
Noise from an outside fan can carry beyond the kitchen. It’s often down to loose mounts or worn bearings.
Motors and bearings
An overheating motor is a warning sign. The cause might be grease restricting the airflow, or the motor itself may be failing.

Extract fan repair around Dulwich Village
The FSA’s food hygiene register shows about 342 cafés, restaurants and staff canteens and about 202 takeaways in and around Dulwich Village, up to about a mile and a half out. Every one of them that cooks under a canopy depends on its extract fan to keep cooking. Kitchens in Dulwich Village get their food hygiene inspections from Southwark council. A kitchen with no working extract can fall short of the suitable and sufficient ventilation food hygiene rules expect. A kitchen without a working fan has a problem to fix quickly. A failed fan in a London kitchen normally means a closed kitchen, so access details help us plan the repair.
Occasional-use kitchens, such as a hall kitchen near St Barnabas' Church or elsewhere in Dulwich Village, are where a stiff or seized fan can turn up. For kitchens close to North Dulwich station, a fan that stops mid-service needs fixing fast, and our emergency line runs 24/7. If you run a school kitchen, at a school such as Dulwich Hamlet Junior School or nearby, a fan that’s getting noisy is best repaired in the holidays before it fails in term.

Honest limits
We won’t sell you work that doesn’t address the problem, so these are the things it won’t cover:
- Smells from the discharge that need odour control equipment
- Faults on the gas side of an interlock system, which need a Gas Safe registered engineer
- Faults in the building’s electrical supply, which need an electrician
If in doubt, ring 0345 646 2711 or email us and we will say what we think.

How the visit works
When we arrive, we check the system against the survey or the photos you sent. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes anything from an hour or two to a full visit, depending on the fault. We fit London jobs around the building rather than the other way round, so a visit in Dulwich Village is normally out of hours.
- We start with the symptoms, such as rattling, humming, slow running or a fan that will not start.
- Power to the fan is isolated before we open the housing.
- Each part is checked in turn: motor, bearings, drive, impeller and fixings.
- 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.
Preparing for the visit
- Agree a time when the area can be out of use
- Clear loose items from the work area
- Arrange a key holder or contact on site

Your questions about extract fan repair in Dulwich Village
Do you work overnight in Dulwich Village?
Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in Dulwich Village needn’t be disturbed. Your opening times are the first thing we ask for.
Does London parking affect a job in Dulwich Village?
Tell us where a van can stop near your site in Dulwich Village, and about any building rules on loading. Working overnight, as we often do in London, usually makes it simpler.
How long will the fan be out of action?
A typical repair takes an hour or two to diagnose, then longer if parts or a new fan are needed including running the fan afterwards. We’ll fit it around the kitchen’s hours where possible.
What is TR19?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t law, but it’s the benchmark.
Is repair an option before replacing the whole fan?
That depends on what we find. After diagnosing, we explain whether it can be repaired, then give you a fixed quote.
Do you cover Dulwich Village?
Yes. Our technicians work in Dulwich Village, within the South East and London area we cover.
Are you insured?
Yes, fully. We also hold CHAS and SafeContractor, for sites that check contractor safety.
Do you replace extract fans as well as repair them?
Yes. If repair isn’t sensible, we replace the fan. The replacement has to suit the ductwork and the cooking before recommending a unit.
What your team can do, and what needs us
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs 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 grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
