About our extract fan repair in Hendon

Kitchens in Hendon call us about extract fans and motors that are noisy, slow or dead, we find the cause and quote a fixed price to repair or replace it. When the fan gives up mid-service, our 24/7 emergency line is there. We are often asked to deal with a knocking noise from the extract fan and a belt-driven fan that squeals, across fan housings, fan motors and bearings.

Replacing a fan in a London building often means working at height or in a tight plant space, and in Hendon, parking and lifting are part of that. Work can be done after service, so the kitchen loses as little time as possible.

It’s worth checking any contractor’s accreditations. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

Common problems we fix in Hendon

Fan bearings do not last for ever, especially in a hot, greasy airstream. Worn bearings whine, rumble or grind, and if they’re left they can seize.

It’s time to book a visit if you see:

  • A failed fan that needs a replacement
  • A belt-driven fan that squeals
  • A fan shaking on its mountings
  • A whining or grinding extract motor

For kitchens close to Hendon station, a fan that stops mid-service needs fixing fast, and our emergency line runs 24/7.

How to choose an extract cleaning contractor

When something else is needed

Not every problem is solved by extract fan repair, and we’ll tell you before work begins. It will not put right:

  • Problems with the electrical supply to the fan (an electrician’s job)
  • Grease build-up in the rest of the extract system
  • Odour complaints that need filtration rather than a fan repair

If in doubt, call us on 0345 646 2711 or email us and we will say what we think before you book.

Extract fan repair in Hendon: local notes

The FSA’s food hygiene register shows about 188 restaurants, cafés and canteens and about 119 sandwich bars and takeaways within 1.5 miles or so of the middle of Hendon. Wherever they cook under a canopy, a failed extract fan stops the kitchen. Environmental health officers from Barnet council inspect food businesses in Hendon. Food hygiene rules expect food premises to have suitable and sufficient ventilation. That makes a fan repair urgent rather than something to put off. 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 Christ Church Hendon or elsewhere in Hendon, are where a stiff or seized fan can turn up. For school kitchens, at schools like Hendon School for example, a planned fan repair in the holidays avoids losing lunches in term time.

How it works

Protection comes first: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. The work on site takes a few hours for most repairs, longer for a full fan replacement, and we clear up before we go. In a London area like Hendon, parking, loading and building access are planned before the day of the work.

  1. You describe the fault and we arrange a visit.
  2. On site, the fan is safely isolated.
  3. We diagnose the fault, checking the controls as well as the fan.
  4. A fixed quote for the repair or replacement follows.
  5. The work is done and the fan is tested running.

Preparing for the visit

  • Make sure someone can let us in and lock up afterwards
  • Let us know about parking and loading
  • Make sure equipment near the work can be switched off and left to cool

Advice

Common questions in Hendon

Do you work overnight in Hendon?

Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in Hendon needn’t be disturbed. When you phone us on 0345 646 2711, or send details by email, mention when the site is quiet.

Is parking a problem for work in Hendon?

We plan it in advance, so let us know about loading bays, permits and access rules at the building. Working overnight, as we often do in London, normally makes it simpler.

Do you provide a certificate or report?

Yes, on every job. It’s a dated, written report with pictures, and TR19® Grease cleans come with a certificate through the BESCA VHE portal. File it with your fire safety records.

What if parts of the system can’t be reached?

The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, and we can fit those.

Are you fully insured?

Yes. Full insurance covers our work and have been trading since 2009.

Which kinds of sites do you work on?

All kinds of commercial and public premises: kitchens, offices, schools, healthcare, retail, leisure and food production. We fit the work around how the site operates.

What will a fan repair or replacement cost?

The cost depends on what’s wrong and how easy the fan is to reach. After diagnosing, you get a fixed quote before any work starts.

Is repair an option before replacing the whole fan?

That depends on what we find. We diagnose first and tell you whether a repair is realistic, then give you a fixed quote.

Between visits

How long the results last depends on use and care. We suggest:

  • Make sure every filter is in place and clean
  • Note when the fan trips or cuts out
  • Book regular TR19 cleaning, which includes the fan
  • Tell us about a new rattle or whine right away

If parts have to be ordered, we tell you how the kitchen can carry on in the meantime. The fan is completed on a return visit at a time that suits your service.

Clogged filters make the fan strain. Keeping filters clean eases the strain and protects the motor.

How the job changes from site to site

Belt-driven fans

Belt drives have more moving parts than direct-drive fans. More parts to inspect, but many faults are straightforward to fix.

Fan controls

Supply faults are a job for an electrician. We will tell you if that is what we find and explain what we found.

Staff cleaning versus specialist work

Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.

Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that’s where we come in.

Why deal with it now?

Wherever the kitchen is, Hendon included, the fan often sits on an outside wall or roof, so its noise does not stay in the kitchen. Dealing with the fault brings the noise back down before it becomes a nuisance. Planning ahead in Hendon lets you pick a quiet night rather than lose a busy one.

Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll go through it with you.
