How we handle extract fan repair in Longfield

Everything a kitchen extract does depends on the fan. When it starts to rattle, hum or slow down, the kitchen gets hot and smoky very quickly. We find out why and put it right, by repairing the fan or replacing it. The work covers belts and pulleys, fan housings and bearings, and common reasons people get in touch are poor airflow at the canopy and an extract that vibrates through the ductwork.

In a village or hamlet like Longfield, the kitchens with extract fans are few, wherever there are any. A failed fan stops the kitchen, and our 24/7 emergency line covers rural addresses too.

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.

For landlords and multi-site operators

Whether it’s one building or many, the standard is the same: a survey first, a fixed quote, the work timed around the site and a report with photos.

Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.

What extract fan repair looks like in Longfield

There are about 6 restaurants, cafés and works canteens and about 6 takeaways and sandwich shops across Longfield and its immediate surroundings (about a mile and a half), according to the Food Standards Agency’s register. A kitchen with a dead extract fan gets hot and smoky fast, and kitchens like these feel it at once. Kitchens in Longfield get their food hygiene inspections from Dartford council. A kitchen with no working extract can fall short of the suitable and sufficient ventilation food hygiene rules expect. That’s one more reason not to keep cooking with a broken fan. About 19 miles out from central London, Longfield is part of the South East area we work across. We work evenings, overnight and at weekends, so the visit fits around the site.

If you cook near Longfield station, long trading hours wear fan belts and bearings, so noise and vibration are worth reporting early. Holidays are the time to replace a tired kitchen fan at schools such as Longfield Academy, rather than mid-term.

When it’s something else

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

  • A greasy canopy and duct that a fan repair will not touch
  • Smells from the discharge that need odour control equipment
  • Faults on the gas side of an interlock system, which need a Gas Safe registered engineer

If in doubt, call 0345 646 2711, or send details by email and we’ll say what we think.

What the work covers

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

What your team can do, and what needs us

Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That is our job.

Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that is where we come in.

Why deal with it now?

A fan that’s running slowly isn’t clearing the kitchen properly. The kitchen becomes an uncomfortable place to work, and more grease settles where it shouldn’t. Rural sites cannot always move to another kitchen or room when something fails.

You will not find a price list here, because the cost depends on the site in front of us. For a fixed quote, ring 0345 646 2711 or email us, and we will explain what it covers.

Keeping the system healthy

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

  • Make sure every filter is in place and clean
  • Book regular TR19 cleaning, which includes the fan
  • Avoid lowering the speed to quieten a fault
  • Keep the area around the fan controls clear

Clean filters help a repaired fan stay that way. The less grease that reaches the fan, the longer its parts last and the quieter it runs.

Regular TR19 cleaning includes the extract fan. Keeping grease off the impeller is one of the simplest ways to protect it and that means less wear.

Questions from Longfield

Which environmental health team covers Longfield?

In Longfield, it’s Dartford council that carries out food hygiene inspections. Inspections are risk-based, so a visit can come at any time, including the week a fan stops.

Can you come to Longfield after we close?

Yes, out-of-hours work is a big part of what we do. The work in Longfield can fit around your hours. Tell us your opening hours when you ask for a quote.

Are you accredited?

Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

Does a fan repair include cleaning the ductwork?

A fan repair on its own doesn’t include the ductwork. We will tell you what we see, so you can decide whether to book a TR19 clean.

Do you offer maintenance contracts?

Yes. Plans on a 3, 6 or 12-monthly cycle are available, to suit the system and how it’s used.

How long will the fan be out of action?

It depends on the fault, but most jobs take a few hours for most repairs, longer for a full fan replacement. You’ll know more once we have found the fault.

Will we have to shut during the visit?

Not usually. We work when the area is out of use, such as evenings, overnight, early mornings or weekends, so the site can carry on as normal.

How much notice do you need?

It depends on the time you need and how big the job is. Tell us your preferred dates when you ask for a quote, and for anything urgent, ring our 24/7 emergency line.

Common problems we fix in Longfield

Any kitchen that cooks for long hours works its fan hard, in Longfield or anywhere else. On belt-driven fans, belts stretch, crack and start to slip and a slipping belt means slower fan speed and weaker extraction.

The symptoms we are asked about most are:

  • A fan worn beyond sensible repair
  • An extract that vibrates through the ductwork
  • A fan running too slowly to clear the kitchen
  • A whining or grinding extract motor

Occasional-use kitchens, such as a hall kitchen near Church of Saint Mary Magdalene or elsewhere in Longfield, are where a stiff or seized fan can turn up.

Questions to ask before booking

  • When the next visit should be, and why
  • Whether the price is fixed
  • Which accreditations they hold, and whether you can check them
  • Exactly which parts of the system are covered

Our hiring checklist

How the visit works

At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and the same goes into the written report. The visit takes a few hours for most repairs, longer for a full fan replacement. If the van will struggle with a lane or gateway near Longfield, let us know and we will plan around it.

  1. You describe the fault and we arrange a visit.
  2. We isolate the fan before touching it.
  3. We diagnose the fault, checking the controls as well as the fan.
  4. A fixed quote for the repair or replacement follows.
  5. We fix the fault and run the fan to check it.

Before we arrive

  • Plan for cooking equipment or plant to be off before we arrive
  • Tell us where we can park and unload
  • Tell us the best time to work, such as after service or at a weekend
