Extract fan cleaning for sites in St Margarets

Extract fan cleaning in St Margarets

A fan never collects grease in a neat, even layer. Uneven build-up unbalances the impeller, leading to vibration, noise and strain on the motor and bearings. A thorough clean removes the cause. Common call-outs are for a smell of hot grease from the extract and a fan motor running hot under a coat of grease, on in-line fans, discharge points and roof-mounted fans.

In a London area like St Margarets, a kitchen extract often passes through shared space on its way out: a riser, a service void, the floors above. A duct fire there can reach parts of the building far from the range, which is why keeping it clean to TR19® matters.

We have been trading since 2009, and we’re 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.

Extract fan cleaning in St Margarets: the local picture

Look up St Margarets on the FSA’s food hygiene register and you’ll find about 293 restaurants, cafés and works canteens and about 47 sandwich bars and takeaways in and around St Margarets, up to about a mile and a half out. Grease builds up on fan blades and housings in kitchens like these, unbalancing the impeller. In St Margarets, food businesses are inspected by environmental health officers from Richmond-Upon-Thames council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A dated certificate in the maintenance file answers the question before it’s asked. London jobs typically start after the last service, with loading and roof access agreed with the building first.

Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Richmond House is about 1 mile south), access may need planning. Bursars and site managers at schools such as Worple Primary School tend to book extract cleaning for when the kitchen is empty.

What we do, step by step

When we arrive, we check the system against the survey or the pictures you sent. Anything unexpected is raised with you before we go further. From there, it takes a few hours where there are several fans or heavy deposits. In St Margarets, as across London, we typically work overnight or at weekends and hand the site back ready to open.

  1. First we locate the fan and agree how it’s safely isolated.
  2. Power to the fan is isolated before anyone touches it.
  3. The impeller and the housing around it are scraped clean.
  4. Blades, housing and the area around the motor are degreased with care.
  5. We reassemble, run the fan and photograph the result.

How to prepare

  • Let us know about permits to work or site inductions
  • Allow time for equipment near the work to be turned off and cool down
  • Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas

Ask for a quote

We do not publish a price list, because every site is different. We look at your system first, from photos or on a visit, and then send you a fixed quote. To get going, phone us on 0345 646 2711 or email us.

What extract fan cleaning can’t fix

In fairness, there are a few things this work will not fix:

  • A failed motor or worn bearings (that needs a fan repair or replacement)
  • A fan that was never right for the kitchen
  • Grease in the canopy and ductwork

Not sure which it is? You can phone us on 0345 646 2711 or email us and we will tell you honestly before booking.

Where we work

  • Discharge points
  • In-line fans
  • Centrifugal fans
  • Roof-mounted fans
  • Axial fans
  • Fan housings

Leave it or put it right?

A fan that sounds rough in St Margarets is often telling you the extract needs a clean. If the fan is coated, the duct before it normally is too so a full TR19 clean may be due. Every month a London system goes without attention adds to what has to be done later.

Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we will explain each part.

What you get with us

  • Fully insured
  • CHAS and SafeContractor accredited, with ISO 9001
  • One number for every site across the South East and London
  • Work around your opening hours, with 24/7 emergency cover

Common questions in St Margarets

Do you clean school canteen extracts around St Margarets out of term?

Yes, out-of-term visits are normal for schools. With about 21 schools and colleges on the FSA’s register within roughly a mile and a half of St Margarets, it pays to plan holiday dates ahead. Booking early in the term gives the best choice of holiday dates.

What do you need to know about parking in St Margarets?

We plan it in advance, so let us know about loading bays, permits and access rules at the building. Where restrictions apply in the day, an evening or overnight visit usually gets round them.

How often does the fan need cleaning?

It’s cleaned with the whole extract, from every 3 months for 12 to 16 hours of cooking a day to every 12 months for 2 to 6 hours. Grease readings and the fan’s condition can show it needs more.

What accreditations do you have?

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.

Who is the responsible person?

Under the Regulatory Reform (Fire Safety) Order 2005, it’s the responsible person: often the employer, owner or occupier. Landlords, facilities managers and managing agents can also hold responsibility.

Do you survey before quoting?

Yes. Every job is surveyed first, either from pictures and details you send or on a site visit. Then you get a fixed quote.

What makes a kitchen extract fan vibrate?

Uneven grease on the impeller often causes it. We clean the fan and tell you if anything else, like worn bearings, is to blame.

Where does the waste go?

It’s contained and taken away. We collect grease, debris and waste water as we go, so it doesn’t spread.

What affects the cost of extract fan cleaning

Some jobs are bigger than they look, and some smaller. What affects the quote:

  • One-off work versus a regular cycle
  • The scale of the work
  • Parking and loading at the site
  • What state the system is in

One small site or a whole estate, the quote is built the same way: the work involved, the access and the timing. You will have a fixed price before we start.

What we need to know

To speed up the quote, please include:

  • Problems your staff have spotted
  • The postcode and the type of business
  • Your opening hours and when the area is out of use
  • Wide photos of the system and the area around it

Photos are the quickest way to a quote: 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

When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.

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. Leave those to us.

What the work involves, part by part

Wall fans

A wall fan pushes the air straight outside. We isolate it, then clean the blades and housing.

Kitchens with long cooking hours

A fan in a long-hours kitchen runs for most of the day, which means grease and wear add up quickly. Regular cleans help it keep going.

When to call us in St Margarets

Grease condenses as the air cools, and on a roof or outside wall the fan can be in some of the coolest air in the system. That makes it a natural place for grease to settle.

Common reasons sites call us are:

  • A heavily greased fan housing
  • Weak extraction at the canopy
  • Grease escaping from the fan outlet
  • Hot, greasy smells near the fan

Commuter trade near St Margarets (London) station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands.
