Extract fan repair in North Cray, done properly

Grease is hard on extract fans. Deposits on the impeller throw it out of balance, which shakes the bearings and mountings. So when we repair extract fan, we look at the grease too and can arrange a TR19® clean of the whole system at the same time. If you’re dealing with a squealing belt on start-up and an extract fan that has stopped working, we can help.

Rooftop fans in London take the weather as well as the grease from below, and in time, bearings, belts and motors fail. Noise and vibration are worth reporting before the fan stops.

The paperwork matters as much as the work. Each visit is written up with pictures, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

What affects the cost of extract fan repair

Before we fix a price, we need to know a few things. We check:

  • The number of sites or systems
  • Any permits to work or inductions
  • A single visit or a regular plan
  • How big the system is

Every site is different, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all make a difference.

Asking for a quote

We can often survey from photos. The most useful are:

  • The roof, plant room or outside wall the system runs to
  • Anything you’ve noticed, such as smells, noise, drips or poor airflow
  • Your last certificate, test record or report
  • Where the site is and what kind of site it is

The quickest way to a quote is to send photos: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.

What your team can do, and what needs us

Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.

For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.

The process

We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool before work begins, and the area around the work is covered and protected. On site, it takes a few hours on site, depending on the fault and the access to the fan. Night and weekend working is normal for us in London, and a site in North Cray is no exception.

  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. The fan is repaired or replaced, then checked running.

Preparing for the visit

  • Agree a time when the area can be out of use
  • Mention any locked doors, roof access or ceiling voids
  • Let us know about permits to work or site inductions

Ask for a quote

There’s no standard price list, because no two systems are the same. We look at your system first, from photos or on a visit, and then send you a fixed quote. To start, give us a ring on 0345 646 2711, or send details by email.

Advice

Extract fan repair around North Cray

There are about 73 restaurants, cafés and works canteens and about 27 takeaways and sandwich shops within roughly a mile and a half of the centre of North Cray, according to the Food Standards Agency’s register. Every one of them that cooks under a canopy depends on its extract fan to keep cooking. It’s Bexley council that sends environmental health officers to food businesses in North Cray. A kitchen with no working extract can fall short of the suitable and sufficient ventilation food hygiene rules expect. A kitchen without a working fan has a problem to fix quickly. We ask about access first for a London fan job, because roofs and basements need planning.

If you manage a school such as Royal Park Primary Academy and the kitchen fan is getting louder, the next break is the time to deal with it. If you cook near Albany Park station, long trading hours wear fan belts and bearings, so noise and vibration are worth reporting early. If you run a church or community hall kitchen, near Parish Church of St James or elsewhere in North Cray, an extract fan that rarely runs can seize or fail when it’s needed.

What happens if it’s left?

Some kitchens run a noisy fan on a lower speed to cut the noise. It hides the symptom and weakens the extract while the underlying wear continues. Diagnosing the fault properly is the lasting answer. It’s better booked as a planned job in North Cray than handled as an emergency.

Working hours, access and the scale of the site can all change the price. Each of those is built into the quote, and the price is fixed before work begins.

Keeping the system healthy

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

  • Make sure staff know who to call if the fan fails
  • Keep a record of any trips or stoppages
  • Get a noisy fan checked rather than slowed down
  • Keep the grease filters clean and fitted

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 is 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.

What a clean won’t put right

To be straight with you, there are a few things this work will not fix:

  • Smells from the discharge that need odour control equipment
  • An extract system that was undersized from the start
  • Grease build-up in the rest of the extract system

If you’re not sure, just call 0345 646 2711 or drop us a line and we will give you a straight answer.

Where we work

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

Different parts, different methods

Motors and bearings

Rumbling and grinding normally come from the bearings. We diagnose whether it’s the bearings or the motor itself before recommending a fix.

Fan controls

Supply faults are a job for an electrician. If that is the cause, we’ll say so and explain what we found.

North Cray questions

Can you work in North Cray outside opening hours?

Yes. We work evenings, overnight and at weekends. That way a site in North Cray doesn’t have to lose a day’s trading. Just give us a ring on 0345 646 2711 or send us an email with your opening times and we will plan around them.

What if my kitchen extract fan stops in North Cray at night?

Our emergency line runs 24/7, and North Cray is within the area we cover. Call 0345 646 2711 and tell us what the fan is doing, or not doing. A photo of the fan’s rating plate helps.

Will we have to shut during the visit?

Not usually. The area we are working in has to be out of use while we are there, so we book a time when it would be closed anyway.

What if parts of the system can’t be reached?

We never leave them off the paperwork. You’ll know exactly which parts weren’t reached and why, and we can quote to improve the access.

What does TR19 mean?

A BESA specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not law, but it’s the benchmark.

How much time does a fan repair need?

A typical repair takes part of a day for most faults, with a return visit if parts have to be ordered including running the fan afterwards. We plan the work around your service where possible.

Can one contract cover all our sites?

Yes. Tell us the addresses and what each needs and you will get one fixed quote.

Can you supply and fit a replacement fan?

We can. We fit replacement fans as well as repairing old ones and we will talk you through what’s involved.
