How we price extract fan repair

We quote each job individually. These are the things that affect it:

  • How many systems or sites are involved
  • Parking and loading at the site
  • One-off work versus a regular cycle
  • The times the site is available

Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we will go through it with you.

Helping us quote

The more you tell us, the more accurate the quote. With your enquiry, please include:

  • The paperwork from the last visit, if you have it
  • Anything you’ve noticed, such as smells, noise, drips or poor airflow
  • Where the site is and what kind of site it is
  • The times we could work without disrupting the site

Need a price for extract fan repair? Please phone us on 0345 646 2711, or send details by email with a few details about the site. We’ll explain what we’d do and send a fixed quote before anything is booked.

About our extract fan repair in Stanborough

Across Stanborough, we deal with fan faults of every kind, from a squeal at start-up to a fan that won’t run at all. The fault is diagnosed, quoted at a fixed price and put right, or the fan is replaced if repair doesn’t make sense. If you have a humming noise from the fan motor and a worn or slipping fan belt, we can put it right.

Rural kitchens often have fans mounted on outside walls or roofs, exposed to the weather. That, with the grease, is hard on motors and bearings.

The sign-off is always in writing: a written report, dated and illustrated with pictures, 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.

What extract fan repair can’t fix

We’d rather tell you now than book work that will not help, so here are the limits:

  • Wiring and supply faults beyond the fan itself
  • A system that needs redesigning rather than repairing
  • Odour complaints that need filtration rather than a fan repair

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

Parts of the system we cover

  • Kitchen extract fans
  • Fan housings
  • Fan motors
  • Roof and wall fans
  • Bearings
  • Belts and pulleys

Common problems we fix in Stanborough

Not every problem is mechanical. A failed speed controller or a wiring fault can stop a fan so we check the controls before blaming the motor.

The symptoms we’re asked about most include:

  • A worn or slipping fan belt
  • A failed fan that needs a replacement
  • Weak extraction and a smoky kitchen
  • A humming noise from the fan motor

If you run a school kitchen, at a school such as Stanborough School or nearby, a fan that’s getting noisy is best repaired in the holidays before it fails in term.

Before booking anyone

  • What paperwork you get at the end
  • When the next visit should be, and why
  • Which accreditations they hold, and whether you can check them
  • Whether the price is fixed

How to choose an extract cleaning contractor

Stanborough questions

Which council inspects kitchens in Stanborough?

That’s Welwyn Hatfield council, whose environmental health officers carry out food hygiene inspections in Stanborough. 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 at weekends in Stanborough?

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

What paperwork should we keep on file?

Everything that shows the system is looked after: our reports and pictures, any certificates and your in-house logs. One maintenance log per site keeps it simple.

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

Yes. Where a fan is beyond repair, we replace it with one suited to the duct and the kitchen with a fixed price agreed before any work starts.

Do I get a report after the visit?

Yes. You get a written report with pictures after each visit, covering the work, any areas we couldn’t access and the recommended next date. Kitchen extract cleans to TR19® Grease also get a certificate through the BESCA Vent Hygiene Elite portal.

Do you work with multi-site operators?

Yes. Our area covers London and the South East, so we can schedule a run of sites on one programme. Each site gets its own report and photos.

How much time does a fan repair need?

It depends on the fault, but as a guide it takes a few hours for most repairs, longer for a full fan replacement. You will know more once we have found the fault.

What accreditations do you have?

We hold CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.

What your team can do, and what needs us

Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.

Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.

Extract fan repair around Stanborough

Look up Stanborough on the FSA’s food hygiene register and you’ll find about 44 restaurants, cafés and canteens and about 10 sandwich bars and takeaways in Stanborough and the streets around it, up to about 1.5 miles out. For any of them with a canopy, the extract fan is what keeps the kitchen usable. Stanborough, about 21 miles from central London, is within our usual area. We work evenings, overnight and at weekends, so the visit fits around the site. It’s Welwyn Hatfield council that sends environmental health officers to food businesses in Stanborough. Food hygiene rules expect food premises to have suitable and sufficient ventilation. That is one more reason not to keep cooking with a broken fan.

Occasional-use kitchens, such as a hall kitchen near Church of St John the Evangelist or elsewhere in Stanborough, are where a stiff or seized fan can turn up.

Different parts, different methods

Belt-driven fans

Belt drives have more moving parts than direct-drive fans. That means more to check, but often a simpler repair.

Roof and wall-mounted fans

Fans outside are exposed to rain and condensation. Rust on fixings and housings is a frequent find.

For landlords and multi-site operators

When the building owner and the occupier are different, the lease normally sets out who maintains what. We’re happy to deal with either side, and the report can go to both.

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

What we do, step by step

The first job on site is protection: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. The work on site takes anything from an hour or two to a full visit, depending on the fault, and we clear up before we go. Pictures of the system and its access let us plan the work in Stanborough before we set off.

  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. We inspect every moving part and the fixings.
  4. We explain the options and quote a fixed price.
  5. We complete the work and check the fan runs smoothly.

Getting ready for the visit

  • Let us know how we reach the system, including roofs, risers and plant rooms
  • Let us know about parking and loading
  • Tell us about site rules, permits or sign-in

How to get a quote

Quoting starts with a diagnosis, from your photos and details or, where that isn’t enough, a survey on site. Then we send a fixed price so you know the cost before any work starts.
