What we are called out for in St Margarets

Grease that gets past the filters ends up on the fan. Deposits gather on the blades, never quite evenly, so the fan runs out of balance and the noise follows.

It’s time to book a visit if you see:

  • Weak extraction and a smoky kitchen
  • A humming noise from the fan motor
  • An overheating extract motor
  • A fan worn beyond sensible repair

If you cook near St Margarets (London) station, long trading hours wear fan belts and bearings, so noise and vibration are worth reporting early.

Questions to ask before you book

  • Whether the quote is based on a survey or photos
  • Whether they’re fully insured
  • How VAT is shown on the quote
  • If the quote is a fixed price or an estimate

How to choose an extract cleaning contractor

Extract fan repair in St Margarets, done properly

Not every failed fan needs replacing. Often a clean, a new belt or new bearings brings it back, and that is what we’ll recommend. Where the motor has burnt out or the unit is past saving, a replacement suited to the system goes in. The work covers fan housings, kitchen extract fans and fan motors, and common reasons people get in touch are a fan that keeps cutting out and a dead fan motor.

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. A fan that’s noisy or vibrating is giving a warning.

Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

The process

A visit follows the same order every time: protect the area, make the system safe, do the work, tidy up and hand over the paperwork. On site, the work takes a few hours for most repairs, longer for a full fan replacement. Before any visit in St Margarets, we agree where the van can stop and how equipment reaches the system.

  1. We ask what the fan is doing, from noise and vibration to a full stop.
  2. Power to the fan is isolated before we open the housing.
  3. Each part is checked in turn: motor, bearings, drive, impeller and fixings.
  4. We explain the fault and give you a fixed price for the fix.
  5. We fix or replace the fan, then test it running before we leave.

Before we arrive

  • Clear loose items from the work area
  • Let us know when the site is closed or quiet
  • Mention any parking or loading restrictions

When a fan fails in St Margarets

Food Standards Agency records list about 293 restaurants, cafés and works canteens and about 47 takeaways in St Margarets and the streets around it, up to about 1.5 miles out. A kitchen with a dead extract fan gets hot and smoky fast, and kitchens like these feel it at once. In St Margarets, food businesses are inspected by environmental health officers from Richmond-Upon-Thames council. Ventilation is part of food hygiene law, which expects it to be suitable and sufficient. A kitchen without a working fan has a problem to fix quickly. Lifting a replacement fan onto a London roof can need a loading slot and the building’s agreement.

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

Why deal with it now?

A noisy fan rarely fixes itself. Bearings that are left to wear can fail suddenly, and that often happens mid-service. A repair booked now is simpler than an emergency later. A building in St Margarets may have flats or offices above and alongside, and a fault in the system can affect them too.

Working hours, access and the scale of the site all affect the cost. Each of those is built into the quote, and the price is fixed before we start.

When it’s something else

It’s worth knowing the limits before booking:

  • Gas interlock faults that a Gas Safe registered engineer must deal with
  • Wiring and supply faults beyond the fan itself
  • Grease throughout the ductwork, which needs a full TR19 clean

Not sure which it is? You can call us on 0345 646 2711 or send us an email and we’ll tell you honestly before booking.

What we work on in St Margarets

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

What staff can safely do

Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.

If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and quote.

Aftercare tips

How long the results last depends on use and care. Here’s what we suggest:

  • Make sure every filter is in place and clean
  • Make sure the fan is cleaned with the rest of the system
  • Tell us about a new rattle or whine right away
  • Keep all filters fitted while cooking

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.

Regular TR19 cleaning includes the extract fan. A clean impeller stays in balance and that means less wear.

Questions from St Margarets

Does London parking affect a job in St Margarets?

We plan it in advance, so let us know about loading bays, permits and access rules at the building. If the building has a loading slot system, we’ll book into it.

Do you cover St Margarets for emergency fan repairs?

Our emergency line runs 24/7, and St Margarets is within the area we cover. Ring 0345 646 2711 at any hour and describe the fault. A photo of the fan’s rating plate helps.

Will we have to shut during the visit?

Not normally. The area we’re working in has to be out of use while we’re there, so the visit goes in a quiet slot.

Can one contract cover all our sites?

Yes. Send the list of sites and the work at each and we will quote them together.

Do you provide a certificate or report?

Yes. It’s the record insurers and inspectors ask to see: a written, dated record with pictures of what we did and anything we couldn’t access.

Why is our extract fan so noisy?

An unbalanced, greasy impeller vibrates and that is one of the most common reasons. Worn bearings, belts and loose mounts are others.

Which accreditations do you hold?

CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We’ve been trading since 2009 and we are fully insured.

What paperwork should we keep on file?

Visit reports, certificates and your in-house cleaning logs. They’re what an insurer, fire officer or EHO may ask for, so keep them together and easy to find.

What the work involves, part by part

Belt-driven fans

With belts and pulleys, there’s more to wear. That means more to check, but often a simpler repair.

Impellers and housings

The fan housing collects grease too. We check both and cleaning may be part of the fix.
