Extract fan repair near High Barnet

The process

Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. All we need from you is clear access and the right equipment switched off. On site, the work takes anything from an hour or two to a full visit, depending on the fault. Most London sites cannot stop for the day, so work in High Barnet is usually done overnight, early in the morning or at weekends.

  1. We take details of the symptoms and book a time that suits the kitchen.
  2. We isolate the fan before touching it.
  3. We diagnose the fault, checking the controls as well as the fan.
  4. You get a fixed price for putting it right.
  5. The work is done and the fan is tested running.

Getting ready for the visit

  • Make sure equipment near the work can be switched off and left to cool
  • Agree a time when the area can be out of use
  • Clear the space around the work

How to get a quote

Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, the quote is fixed before any work is booked.

How we handle extract fan repair in High Barnet

Grease and fans do not mix. A coated impeller spins unevenly and the vibration wears out bearings and fixings. That is why we check the grease whenever we work on a fan, and a full TR19® clean can be booked alongside. The work covers bearings, fan housings and roof and wall fans, and the jobs we see most are a worn or slipping fan belt and a fan running too slowly to clear the kitchen.

In London, a kitchen without working extraction cannot keep cooking safely. Fans in High Barnet are often on a roof or in a basement at the end of a long duct run, so we ask about access first.

Every visit ends with a written report and pictures, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Between visits

Looking after the system between visits is straightforward, and it makes the next visit easier:

  • Write down when the fan misbehaves
  • Don’t turn the fan down to hide a noise
  • Keep the fan on a planned cleaning cycle
  • Don’t cook with gaps in the filter bank

Before we leave, the fan is run and checked. We explain the fault and the fix, and anything else we noticed is pointed out.

A fan that’s starting to make noise is giving you a warning. Booking a check at this stage keeps it a planned job instead of a breakdown at the worst moment.

Different parts, different methods

Fan controls

Where the fault is in the building’s electrical supply, an electrician is needed. If that’s the cause, we will say so so you know who to call.

Roof and wall-mounted fans

Noise from an outside fan can carry beyond the kitchen. Loose fixings and worn mounts are often the cause.

Staff cleaning versus specialist work

Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.

Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.

FAQs for High Barnet

Do you work overnight in High Barnet?

Yes, evening, overnight and weekend work is normal for us. It means the site in High Barnet keeps running as normal. Tell us your opening hours when you ask for a quote.

Do you cover High Barnet for emergency fan repairs?

High Barnet is covered, and our emergency callout runs 24/7. Use 0345 646 2711, our emergency number, at any time. Tell us where the fan is and how to reach it.

Do you provide a certificate or report?

Yes. It’s your proof that the work was done: a dated report with pictures, listing the work and any areas we couldn’t reach.

What about areas you cannot get to?

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

Do you offer maintenance contracts?

Yes. Regular plans can run on 3, 6 or 12-monthly cycles, to suit the system and how it’s used.

Who is the responsible person?

The law calls them the responsible person. That is generally the employer or the person in control of the premises, and in shared buildings more than one person can have duties. If you’re not sure, check your lease and fire risk assessment.

Why is our extract fan so noisy?

It can be one of a few things, from a worn bearing to a loose fixing. It’s worth having it diagnosed before the fault gets worse.

Does a faulty extract fan always need replacing?

That depends on what we find. After diagnosing, we explain whether it can be repaired and quote a fixed price for the option you choose.

Why deal with it now?

In kitchens with an interlocked gas supply, no extract can mean no cooking. Even without an interlock, cooking without extraction is not sensible, so a failing fan is worth dealing with early. It’s better booked as a planned job in High Barnet than handled as an emergency.

We don’t list prices on the website, because the cost depends on the site in front of us. For a fixed quote, phone us on 0345 646 2711 or send us an email, and we’ll explain what it covers.

What we are called out for in High Barnet

Not every problem is mechanical. A failed speed controller or a wiring fault can stop a fan, and a fan that will not start is not always a dead motor.

It’s time to book a visit if you see:

  • Poor airflow at the canopy
  • An extract fan that has stopped working
  • An extract that vibrates through the ductwork
  • An overheating extract motor

School kitchens cannot easily serve lunch without extraction, so if you look after one at a school like Foulds School, fix a failing fan before term starts.
