About our extract fan repair in Highfield

Everything a kitchen extract does depends on the fan. When it starts to rattle, hum or slow down, the cooking area soon fills with heat and fumes. Our engineers track down the fault and fix it with a repair or a replacement. The work covers kitchen extract fans, bearings and roof and wall fans, and the jobs we see most are an extract fan that rattles or knocks and a dead fan motor.

Around a place like Highfield, a pub, café or care home kitchen with a failed fan cannot carry on cooking as normal. That’s what our 24/7 emergency callout is for.

Good records are part of the job. Each visit is written up with pictures, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

Common problems we fix in Highfield

Some grease always slips past the filters and reaches the fan. It builds up on the impeller blades unevenly, so the fan runs out of balance and starts to vibrate and rattle.

The symptoms we’re asked about most are:

  • A fan rattling in its housing
  • A fan running too slowly to clear the kitchen
  • A fan that whines, hums or grinds
  • A fan shaking on its mountings

Holidays are the time to replace a tired kitchen fan at schools such as Yewtree Primary School, rather than mid-term.

Our hiring checklist

Landlords, agents and facilities managers

When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party and send the paperwork to whoever needs it.

We also work for facilities teams across offices, schools and healthcare in Highfield and across Hertfordshire. Work can be phased by floor, building or site to keep disruption down.

How the visit works

The visit has three parts: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, while signing off means the written report and photos. Most of the time goes on the work itself, and that takes a few hours on site, depending on the fault and the access to the fan. Evenings, weekends or a closed day all work for a site in a place like Highfield.

  1. We start with the symptoms, such as rattling, humming, slow running or a fan that won’t start.
  2. The fan is isolated and opened up so we can see inside.
  3. Each part is checked in turn: motor, bearings, drive, impeller and fixings.
  4. We explain the fault and give you a fixed price for the fix.
  5. Once the work is done, we run the fan and check it’s steady and quiet.

Before we arrive

  • Make sure equipment near the work can be switched off and left to cool
  • Tell us the best time to work, such as after service or at a weekend
  • Let us know about permits to work or site inductions

Advice

What staff can safely do

For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is 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.

What extract fan repair looks like in Highfield

Food Standards Agency records list about 96 cafés, restaurants and staff canteens and about 51 takeaways in Highfield and the streets around it, up to about 1.5 miles out. Those that cook under a canopy rely on a fan that runs every hour they’re open. In Highfield, food businesses are inspected by environmental health officers from Dacorum council. Food hygiene rules expect food premises to have suitable and sufficient ventilation. Getting the fan running again is the priority. About 24 miles out from central London, Highfield is part of the South East area we work across. Evening, overnight and weekend visits are all possible.

A fan that rarely runs, like one in a hall kitchen near St Paul's or elsewhere in Highfield, can seize between uses.

Highfield: your questions answered

Which environmental health team covers Highfield?

In Highfield, it’s Dacorum council that carries out food hygiene inspections. If the extract fan has failed, it’s worth having the repair booked, and the details to hand, before an officer visits.

Do you work in villages like Highfield?

Yes. Highfield is within the area we cover across London and the South East. Just mention lanes, gates or anything else about the site when you book.

What does TR19 mean?

TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.

What accreditations do you have?

We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

Is it worth cleaning the extract while you are fixing the fan?

Doing both together is often sensible. A TR19 clean covers the canopy, plenum, ductwork and fan, with a certificate and photo report.

Who do we call if the fan stops in the middle of cooking?

We run a 24/7 emergency callout for exactly this. We’ll talk it through with you and arrange to attend as soon as we can.

How much notice do you need?

It depends on the time you need and how big the job is. Mention your preferred dates with your enquiry, and if it’s an emergency, call us any time.

Do you offer emergency callouts?

Yes, day and night, every day of the year. Office hours are Monday to Friday, 8am to 6pm, and the emergency line covers the rest.

What affects the cost of extract fan repair

You will get a fixed price before we start. It’s based on:

  • The scale of the work
  • A single visit or a regular plan
  • Whether we need access equipment or extra panels
  • How many systems or sites are involved

One small site or a whole estate, the quote is built the same way: what needs doing, how we get to it and when. You will have a fixed price before we start.

What to send for a quote

When you contact us, these details help:

  • Where the site is and what kind of site it is
  • Any previous report or certificate
  • When the site is open and when it’s quiet
  • Anything you’ve noticed, such as smells, noise, drips or poor airflow

We do not publish a price list, because every site is different. Instead, we look at your site first, from photos or a survey, then send a fixed quote. To start, phone us on 0345 646 2711 or use the quote form.

Why act early in Highfield

In Highfield, as elsewhere, an extract fan may well sit outside on a wall or roof, where a rattle or a whine can be heard beyond the kitchen. Dealing with the fault brings the noise back down before neighbours notice. You choose the date of a planned visit, and a breakdown never asks.

Working hours, access and the scale of the site can all change the price. We take each of them into account and give you a fixed price before we start.

Why book with us

  • Out-of-hours work and a 24/7 emergency line
  • CHAS and SafeContractor accredited, with ISO 9001
  • Trading since 2009
  • Full insurance on every job
