Extract fan repair in Grange Mills
Wherever your kitchen is in Grange Mills, fan work means the extract has to be isolated, so the job is fitted around the kitchen’s hours. Evenings, overnight and weekends are all possible, and a fan that dies mid-service can go straight to our 24/7 line. We are often asked to deal with a fan worn beyond sensible repair and a knocking noise from the extract fan, across fan housings, bearings and roof and wall fans.
London extract fans often sit on rooftops, exposed to the weather as well as the grease, and bearings, belts and motors wear out in the end. A fan that is noisy or vibrating is giving a warning.
Nothing is signed off by word of mouth: a dated report with photos of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

When to call us in Grange Mills
Over the years, mountings loosen and rubber mounts break down. Then every vibration is passed into the duct and the building and that is a common source of rattles.
Clients usually contact us after spotting one of these:
- Weak extraction and a smoky kitchen
- A failed fan that needs a replacement
- A knocking noise from the extract fan
- A fan that keeps cutting out

Extract fans in Grange Mills
Look up Grange Mills on the FSA’s food hygiene register and you’ll find about 716 cafés, restaurants and staff canteens and about 179 takeaways and sandwich shops in Grange Mills and the streets around it, up to about 1.5 miles out. For any of them with a canopy, the extract fan is what keeps the kitchen usable. Kitchens in Grange Mills get their food hygiene inspections from Wandsworth council. Food hygiene rules expect food premises to have suitable and sufficient ventilation. That’s one more reason not to keep cooking with a broken fan. A failed fan in a London kitchen usually means a closed kitchen, so access details help us plan the repair.
Holidays are the time to replace a tired kitchen fan at schools such as Henry Cavendish Primary School, rather than mid-term.

Your questions about extract fan repair in Grange Mills
What if my kitchen extract fan stops in Grange Mills at night?
Our emergency line runs 24/7, and Grange Mills is within the area we cover. Ring 0345 646 2711 at any hour and describe the fault. If you can, stop cooking until the fan is checked.
Who would carry out a food hygiene inspection at a kitchen in Grange Mills?
Kitchens in Grange Mills are inspected by Wandsworth council’s environmental health officers. Keeping the fan serviced is easier than explaining a broken one on inspection day.
What about areas you can’t get to?
Anything we can’t reach goes on the report, with photos where possible, and we explain what access is needed, such as extra access panels in ductwork.
Can you tell me the price of a fan repair?
Every fan job is priced once we know the fault. Repair, parts or a full replacement all cost differently, so call us on 0345 646 2711 or email us and we’ll arrange a diagnosis.
What causes a noisy extract fan?
It can be one of a few things, from a worn bearing to a loose fixing. The safest step is a proper diagnosis before it leads to a breakdown.
Are you accredited?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.
What do you do to protect the area?
With sheeting and covers, before anything else happens. The work is kept contained and leave the area clean.
Can you repair a fan rather than replace it?
We look at repairing it first. If the fan is past saving, a replacement may be more sensible, and we’ll explain why.
How the visit works
The visit has three parts: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and photos. The middle part takes longest, and that takes a few hours for most repairs, longer for a full fan replacement. Managed blocks in London often need contractors booked in ahead, and we’re happy to deal with the agent directly for a site in Grange Mills.
- We take details of the symptoms and book a time that suits the kitchen.
- On site, the fan is safely isolated.
- We diagnose the fault, checking the controls as well as the fan.
- You get a fixed price for putting it right.
- The work is done and the fan is tested running.
Preparing for the visit
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Mention any parking or loading restrictions
- Clear loose items from the work area
Getting a quote
To help us quote: the address, the type of site and when it’s open, photos of the system and the last certificate or report, if there is one. Then give us a ring on 0345 646 2711, or email photos.

What happens if it’s left?
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 and fixing the fan early avoids a forced shutdown. Leaving it on a busy London site only adds to the work.
You will not find a price list here, because the cost depends on the site in front of us. For a fixed quote, ring 0345 646 2711 or email us, and we will explain what it covers.

Honest limits
Extract fan repair cannot fix everything, and we’ll tell you before work begins. It will not put right:
- Odour complaints that need filtration rather than a fan repair
- Problems with the gas supply or its interlock valve
- A greasy canopy and duct that a fan repair will not touch

Aftercare tips
So the system stays in good health:
- Don’t wait for a noisy fan to stop
- Keep a record of any trips or stoppages
- Never run the extract with filters missing
- Make sure the fan is cleaned with the rest of the system
If the fan had grease on it, the rest of the system almost certainly does too. A full TR19® clean deals with the canopy, ductwork and fan together, with a certificate and photo report.
Regular TR19 cleaning includes the extract fan. Keeping grease off the impeller is one of the simplest ways to protect it, so planned cleaning helps the fan last.
Staff cleaning versus specialist work
Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
What the work involves, part by part
Impellers and housings
Grease settles inside the fan housing as well as on the blades. Both are inspected, and cleaning can form part of the repair.
Direct-drive fans
An impeller coated in grease vibrates straight into the motor bearings. Cleaning it can cure the noise, if the bearings haven’t been damaged.
