Extract fan repair for kitchens and businesses in Clapham Park
Our engineers handle all sorts of fan faults in Clapham Park, from a squeal at start-up to a fan that won’t run at all. We find the cause, give you a fixed price and fix it or fit a replacement when it’s beyond repair. The work covers fan housings, fan motors and bearings, and the jobs we see most are vibration spreading from the fan into the ducts and weak extraction and a smoky 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.
The paperwork matters as much as the work. You get a written report with photos after each visit, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

When a fan fails in Clapham Park
Look up Clapham Park on the FSA’s food hygiene register and you’ll find about 672 cafés, restaurants and staff canteens and about 225 takeaways in and around Clapham Park, up to about a mile and a half out. Those that cook under a canopy rely on a fan that runs every hour they’re open. Lifting a replacement fan onto a London roof can need a loading slot and the building’s agreement. In Clapham Park, food businesses are inspected by environmental health officers from Lambeth council. Under food hygiene rules, a kitchen needs suitable and sufficient ventilation. So a failed fan is worth fixing before the next service, not the next month.
Holidays are the time to replace a tired kitchen fan at schools such as Glenbrook Primary School, rather than mid-term. Hall kitchens near Church of the Holy Spirit, or anywhere around Clapham Park, often use their fans only now and then, and an idle fan can stick.
Clapham Park is about 1 mile south-west of Stockwell, in Greater London. Wherever you are in the SW4 postcode area, we can carry out extract fan repair at your premises. Clapham Park is one of 764 places in Greater London where we work for commercial clients.

Clapham Park’s nearest station is Clapham High Street station, roughly 0.8 miles north of the centre.

Keeping the system healthy
Aftercare is simple, and it helps at the next visit:
- Note when the fan trips or cuts out
- Keep the fan on a planned cleaning cycle
- Clean or change filters on schedule
- Keep the area around the fan controls clear
Listen to the fan over the next few weeks. A new noise or vibration is worth reporting early, so it can be looked at before it grows.
A scheduled maintenance plan keeps the whole system on a regular cycle, so the fan is looked at as part of each visit and wear is caught earlier.
The process
Our technicians bring everything the work needs, including protection sheets, the right tools and access kit. You only need to give us clear access and switch off what needs to be off. On site, the work takes an hour or two to diagnose, then longer if parts or a new fan are needed. Managed blocks in London often need contractors booked in ahead, and we are happy to deal with the agent directly for a site in Clapham Park.
- We agree a time to attend, out of hours if needed.
- The extract is switched off and the fan opened up.
- We inspect every moving part and the fixings.
- You hear whether repair or replacement makes sense, with a fixed quote.
- The fan is repaired or replaced, then checked running.
How to prepare
- Clear the space around the work
- Let us know how we reach the system, including roofs, risers and plant rooms
- Allow time for equipment near the work to be turned off and cool down
How to get 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 any work starts.
Advice
Staff cleaning versus specialist work
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
Questions from Clapham Park
Can you come to Clapham Park after we close?
Yes, we can come after you close and finish before you open. The work in Clapham Park can fit around your hours. When you give us a ring on 0345 646 2711 or use the quote form, mention when the site is quiet.
Is parking a problem for work in Clapham Park?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. If the building has a loading slot system, we will book into it.
Is there a survey before the work?
Yes. Every job is surveyed first, either from pictures and details you send or on a site visit. A fixed quote follows.
Does a faulty extract fan always need replacing?
Often, yes. Many faults are fixed by cleaning the impeller or renewing worn parts and we only recommend replacement when repair does not make sense.
Will we have to shut during the visit?
Not normally. We need the work area to ourselves while we are on site, so the visit goes in a quiet slot.
Do you have a 24/7 line?
Yes, any time. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line, and we will advise on what to do next.
How much does an extract fan repair cost?
We cannot price it without knowing the fault. Once we have looked at it, you get a fixed quote for the repair or the replacement.
Are you insured?
Yes. Duct Doctor is fully insured, and the details are available on request.
Signs you need extract fan repair in Clapham Park
Fans everywhere, Clapham Park included, live in a hard environment: heat, grease, steam and long running hours. Moisture can rust housings and fixings, and age catches up with every fan in the end.
Signs it’s time to call us include:
- A squealing belt on start-up
- An extract fan that has stopped working
- An extract that vibrates through the ductwork
- An old fan that needs replacing
If you run a kitchen close to Clapham High Street station and the extract fan is getting noisy, a planned repair after closing beats a breakdown at the rush.
What to look for in a quote
- What hours they’ll be on site
- Whether they recommend a next date
- If they look at the system before pricing
- Whether VAT is included
What happens if it’s left?
A fan that is running slowly is not clearing the kitchen properly. The kitchen becomes an uncomfortable place to work, and more grease settles where it shouldn’t. In Clapham Park, as across London, ductwork often passes through shared risers and other people’s space.
Every site is different, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.
Why us?
- Each visit written up, with pictures
- A BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease
- Fixed quotes from a survey or pictures
- Ventilation hygiene specialists since 2009
