Extract fan repair for sites in Mildmay

About our extract fan repair in Mildmay

Not every failed fan needs replacing. Sometimes cleaning the impeller or renewing worn parts is enough, and that’s what we’ll recommend. When a fan is worn beyond sensible repair, a replacement suited to the system goes in. Common call-outs are for a knocking noise from the extract fan and a squealing belt on start-up, on fan housings, belts and pulleys and bearings.

London extract fans often sit on rooftops, exposed to the weather as well as the grease, and bearings, belts and motors wear out in the end. Noise and vibration are worth reporting before the fan stops.

It’s worth checking any contractor’s accreditations. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

Signs you need extract fan repair in Mildmay

Fans everywhere, Mildmay 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.

Keep an eye out for any of the following:

  • A fan shaking on its mountings
  • A whining or grinding extract motor
  • A failed fan that needs a replacement
  • An extract fan that rattles or knocks

School kitchens can’t easily serve lunch without extraction, so if you look after one at a school like Newington Green Primary School, fix a failing fan before term starts.

How to choose an extract cleaning contractor

Your questions about extract fan repair in Mildmay

Can you work in Mildmay outside opening hours?

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

Who carries out food hygiene inspections in Mildmay?

That’s Islington council, whose environmental health officers carry out food hygiene inspections in Mildmay. Keeping the fan serviced is easier than explaining a broken one on inspection day.

How much time does a fan repair need?

As a guide, it takes a few hours on site, depending on the fault and the access to the fan. If parts have to be ordered, we’ll tell you how long that is likely to be.

Do we lose a day’s trading?

Not normally. We need the work area to ourselves while we are on site, so the visit goes in a quiet slot.

What happens if you can’t reach some of it?

They’re marked on the report. In ductwork, new access panels are often the answer, and we can fit those.

How much notice do you need?

The more notice, the better, particularly for night and weekend visits. Quotes normally come back within one working day, and emergencies are covered by our 24/7 line.

Who is the responsible person?

That depends on who controls the premises. Under the Fire Safety Order 2005, it’s the responsible person, which can be the employer, the owner, a landlord, an FM or a managing agent.

Is there a survey before the work?

Yes, every time. We diagnose before we treat: the survey shows what needs doing and what access we need and the fixed quote is built on it.

What happens on the day

Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and the same goes into the written report. The visit takes anything from an hour or two to a full visit, depending on the fault. In Mildmay, as across London, we normally work overnight or at weekends and hand the site back ready to open.

  1. We ask what the fan is doing, from noise and vibration to a full stop.
  2. The fan is isolated and opened up so we can see inside.
  3. We check the motor, bearings, drive, impeller and mountings.
  4. We explain the fault and give you a fixed price for the fix.
  5. The repair or replacement is carried out and the fan is run and checked.

How to prepare

  • Tell us the best time to work, such as after service or at a weekend
  • Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
  • Clear loose items from the work area

Getting a quote

There’s no standard price list, because every site is different. Instead, we look at your site first, from pictures or a survey, then send a fixed quote. To start, call 0345 646 2711, or email photos.

Advice

Keeping the system healthy

After the visit, a few habits help the work last:

  • Tell us about a new rattle or whine right away
  • Keep the area around the fan controls clear
  • Keep the emergency number where staff can see it
  • Make sure every filter is in place and clean

Clean filters help a repaired fan stay that way. Less grease on the impeller means less wear and fewer faults.

Small faults, like a worn belt, are quick to fix. Left for months, they can damage the motor or bearings, so it’s worth acting early.

Extract fans in Mildmay

There are about 1,023 restaurants, cafés and works canteens and about 225 takeaways within roughly a mile and a half of the centre of Mildmay, according to the Food Standards Agency’s register. For any of them with a canopy, the extract fan is what keeps the kitchen usable. Kitchens in Mildmay get their food hygiene inspections from Islington council. Ventilation is part of food hygiene law, which expects it to be suitable and sufficient. Getting the fan running again is the priority. In London, a fan on a roof or in a basement can take planning to reach, with parking and loading to arrange.

Hall kitchens near Church of St Jude and St Paul, or anywhere around Mildmay, often use their fans only now and then, and an idle fan can stick. For a takeaway near Dalston Kingsland station, a fan that fails on a busy evening means turning customers away, and our emergency line runs 24/7.

What a clean will not put right

It’s worth knowing the limits before booking:

  • Gas interlock faults that a Gas Safe registered engineer must deal with
  • An extract system that was undersized from the start
  • Cooking smells reaching neighbours, which may need odour control

If in doubt, call us on 0345 646 2711, or email photos and we will say what we think.

Parts of the system we cover

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

How the job changes from site to site

Motors and bearings

Rumbling and grinding normally come from the bearings. We diagnose whether it’s the bearings or the motor itself and then recommend the fix.

Belt-driven fans

In a belt-driven fan, the motor drives the impeller by belt. Belts wear, stretch and slip, so we check the pulleys and bearings as well.

Multi-site and managed buildings

Whether it’s one building or many, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with photos.

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. Where responsibility is shared, records matter even more.

What happens if it’s left?

A fan that’s running slowly is not clearing the kitchen properly. Staff work in hotter, steamier air and grease has more chance to settle on surfaces and in the duct. Choosing the date yourself beats having a fault choose it for you.

We don’t list prices on the website, because each job is priced on what it involves. For a fixed quote, call 0345 646 2711 or email us, and we will explain what it covers.
