About our extract fan repair in Clapham

Extract fan repair starts with a diagnosis. Noise can come from grease on the impeller, worn bearings or a slipping belt, while a fan that won’t start may have a motor or control fault. You hear what we’ve found before any work goes ahead. We’re often asked to deal with a fan shaking on its mountings and an old fan that needs replacing, on fan motors, belts and pulleys and roof and wall fans.

For a London kitchen, a failed extract fan normally means the cooking stops, and a closed kitchen loses a night’s trade. Fans in Clapham are often on a roof or in a basement at the end of a long duct run, so we ask about access first.

The sign-off is always in writing: a dated report with pictures of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

Honest limits

Extract fan repair cannot fix everything, and we’d rather say so up front. It doesn’t solve:

  • Wiring and supply faults beyond the fan itself
  • Faults on the gas side of an interlock system, which need a Gas Safe registered engineer
  • Grease build-up in the rest of the extract system

If you’re not sure, just phone us on 0345 646 2711 or email us and we will give you a straight answer.

Managing agents and facilities teams in Clapham

When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.

Keeping records across a portfolio is half the battle. Every visit ends with a dated report and photos, ready to show insurers, fire officers or EHOs.

What your team can do, and what needs us

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.

Staff cleaning and specialist work aren’t the same thing. 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.

Keeping the system healthy

Here’s the after-treatment advice, in brief:

  • Report new noises from the fan early
  • Write down when the fan misbehaves
  • Save our number for the 24/7 emergency line
  • Avoid lowering the speed to quieten a fault

Grease on the fan normally means grease in the duct as well. A full TR19® clean deals with the canopy, ductwork and fan together, with a certificate and photo report.

A 3, 6 or 12-monthly cleaning plan brings us back at set intervals, which means the fan is seen regularly and wear is caught earlier.

Clapham questions

What if my kitchen extract fan stops in Clapham at night?

Our emergency line runs 24/7, and Clapham is within the area we cover. Call 0345 646 2711 and tell us what the fan is doing, or not doing. A photo of the fan’s rating plate helps.

Can the work in Clapham be done at night or at weekends?

Yes, evening, overnight and weekend work is normal for us. Your customers, staff or residents in Clapham needn’t be disturbed. Just call 0345 646 2711 or drop us a line with your opening times and we will plan around them.

What about areas you cannot get to?

They’re listed in the report, never skipped quietly. You’ll know exactly which parts weren’t reached and why, along with a quote to put access in.

Will you fit a new fan if ours can’t be repaired?

We can. We fit replacement fans as well as repairing old ones, and we will explain the options.

Does the report say when we need you again?

Yes. Every report includes a recommended date for the next visit, based on what we found and how the system is used.

Can you repair a fan rather than replace it?

In many cases, yes. Many faults are fixed by cleaning the impeller or renewing worn parts and we only recommend replacement when repair does not make sense.

What do you do with what you remove?

It leaves the site with us when we go. During the work, it’s contained so the area stays clean.

Do you provide a certificate or report?

Yes. You get a written report with photos after each visit, covering the work, any areas we couldn’t access and the recommended next date. Where the work is a TR19® Grease clean, there’s also a certificate issued through the BESCA Vent Hygiene Elite portal.

What we do, step by step

Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so a kitchen or building can carry on as usual the next day. On site, the work takes part of a day for most faults, with a return visit if parts have to be ordered. Expect the work in Clapham to happen after your last customer leaves, not during trading.

  1. A visit is booked, in the evening or overnight if that suits.
  2. The extract is switched off and the fan opened up.
  3. Bearings, drive, impeller, motor and mounts are inspected.
  4. We explain the options and quote a fixed price.
  5. We complete the work and check the fan runs smoothly.

Preparing for the visit

  • Clear the space around the work
  • Arrange a key holder or contact on site
  • Agree a time when the area can be out of use

Extract fan repair in Clapham: local notes

Food Standards Agency records list about 757 cafés, restaurants and staff canteens and about 239 takeaways and sandwich shops in and around Clapham, 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, food businesses are inspected by environmental health officers from Lambeth council. Under food hygiene rules, a kitchen needs suitable and sufficient ventilation. That makes a fan repair urgent rather than something to put off.

Occasional-use kitchens, such as a hall kitchen near St Paul's Church or elsewhere in Clapham, are where a stiff or seized fan can turn up. For school kitchens, at schools like Clapham Manor Primary School for example, a planned fan repair in the holidays avoids losing lunches in term time.

Do you need extract fan repair in Clapham?

Grease that gets past the filters ends up on the fan. It builds up on the impeller blades unevenly, so the fan runs out of balance and the noise follows.

It’s time to book a visit if you see:

  • Vibration spreading from the fan into the ducts
  • Weak extraction and a smoky kitchen
  • A fan worn beyond sensible repair
  • A humming noise from the fan motor

If you run a café or takeaway near Clapham High Street station, a failed fan in the middle of service is exactly what our 24/7 emergency line is for.
