Different parts, different methods

Fan controls

We check the controls as part of every diagnosis since the motor isn’t always to blame.

Motors and bearings

Motors and bearings take the most strain in a kitchen extract fan. Heat, grease and long running hours all wear them.

Extract fan repair for kitchens and businesses in Dartford

Grease is hard on extract fans. A coated impeller spins unevenly and the vibration wears out bearings and fixings. So when we repair extract fan, we look at the grease too, and a full TR19® clean can be booked alongside. We’re often asked to deal with weak extraction and a smoky kitchen and a fan rattling in its housing, across roof and wall fans, kitchen extract fans and bearings.

Many fans around a town like Dartford sit on a flat roof or an outside wall, where they take the weather as well as the grease. Belts, bearings and motors wear out in the end.

Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

Keeping the system healthy

Looking after the system between visits is straightforward, and it helps at the next visit:

  • Keep a record of any trips or stoppages
  • Book regular TR19 cleaning, which includes the fan
  • Keep the grease filters clean and fitted
  • Do not wait for a noisy fan to stop

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.

When filters block, the fan works harder. Keeping filters clean eases the strain and protects the motor.

Multi-site and managed buildings

The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.

Running several sites is easier with one contractor. We cover South East England and London, so a run of sites can go into one programme and kept to a regular schedule.

Signs you need extract fan repair in Dartford

Fans everywhere, Dartford included, live in a hard environment: heat, grease, steam and long running hours. Moisture can rust housings and fixings and eventually any fan simply wears out.

What we’re most often called out for:

  • A fan that keeps cutting out
  • Poor airflow at the canopy
  • A humming noise from the fan motor
  • A fan rattling in its housing

Occasional-use kitchens, such as a hall kitchen near Church of the Holy Trinity or elsewhere in Dartford, are where a stiff or seized fan can turn up.

FAQs for Dartford

Who inspects food businesses in Dartford?

In Dartford, it’s Dartford 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 cover Dartford for emergency fan repairs?

Extract fan emergencies in Dartford are covered around the clock. Ring 0345 646 2711 at any hour and describe the fault. Tell us where the fan is and how to reach it.

Why is our extract fan so noisy?

An unbalanced, greasy impeller vibrates, which is a common cause of noise. Bearings, belts and mountings can also be to blame.

Can one contract cover all our sites?

Yes. We work across South East England and London, so sites at different addresses can be planned together on one programme. Each site gets its own report and photos.

How much notice should we give?

Book as early as you can for planned work, particularly if your next visit is nearly due. For emergencies, we take calls 24/7.

What types of premises do you cover?

Commercial premises of every kind: kitchens, offices, schools, healthcare, retail, leisure and food production. We fit the work around how the site operates.

Is TR19 a legal requirement?

No. TR19® itself isn’t law; it’s a BESA specification. The legal duty comes from the Regulatory Reform (Fire Safety) Order 2005: the responsible person must assess and reduce fire risk, and TR19® is the benchmark for showing that grease in the extract is under control.

Do you replace extract fans as well as repair them?

We do. A replacement is matched to the system it’s going into with a fixed price agreed before work begins.

How the visit works

We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that is an evening, overnight or a weekend. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes a few hours on site, depending on the fault and the access to the fan. In a town like Dartford, we typically work after closing or on a quiet day, so the site opens again on time.

  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.

Before we arrive

  • Mention any locked doors, roof access or ceiling voids
  • Agree a time when the area can be out of use
  • Plan for cooking equipment or plant to be off before we arrive

Getting a quote

For a fixed quote, call 0345 646 2711, or email photos and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. We typically come back within one working day.

Why act early in Dartford

It can be tempting to turn the fan down to quieten it. That reduces extraction without fixing anything, and the fault carries on developing. A proper diagnosis in Dartford gets to the real cause. A small fault found now is a quick job; the same fault found later can close the site.

The cost depends on the size of the system, the condition it’s in and how easy it is to reach. You get a fixed price before any work starts, so you know where you stand.

Staff cleaning versus specialist work

Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.

Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.

Extract fans in Dartford

Look up Dartford on the FSA’s food hygiene register and you’ll find about 85 cafés, restaurants and staff canteens and about 60 sandwich bars and takeaways in Dartford and the streets around it, up to about 1.5 miles out. Every one of them that cooks under a canopy depends on its extract fan to keep cooking. At about 14 miles from central London, Dartford sits well inside the area we cover. A survey and a fixed quote come first, then the visit at a time that suits you. Environmental health officers from Dartford council inspect food businesses in Dartford.
