Extract fan cleaning for sites in Aperfield

Aperfield: your questions answered

Which fire and rescue service is responsible for Aperfield?

Aperfield is in the area of London Fire Brigade. TR19® isn’t law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.

Can you work in Aperfield outside opening hours?

Yes, we can come after you close and finish before you open. That way a site in Aperfield doesn’t have to lose a day’s trading. Let us know the hours you’re closed and we will book within them.

Which accreditations do you hold?

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 are fully insured.

What types of premises do you cover?

Any site with a kitchen or a ventilation system to look after, from a small pub to a hospital. We work with hotels, schools, care homes, offices, retail and leisure sites.

Why has my extract fan got louder?

Build-up on the impeller is a frequent reason, because it unbalances the fan. Worn bearings and motor problems are others, which our report will flag.

What if parts of the system cannot be reached?

Anything we can’t reach goes on the report, with photos where possible, and we tell you what would make it reachable, such as extra access panels in ductwork.

Is there a survey before the work?

Yes. For many sites, photos and a few details are enough, while bigger or harder-to-see systems are surveyed on site.

Is Aperfield in your area?

Yes. Our area takes in London and the counties of South East England, Aperfield included.

About our extract fan cleaning in Aperfield

Is the extract fan louder than it used to be, or the airflow weaker? Tell us about it when you ring 0345 646 2711 or email us, and you will get a fixed price, typically within one working day. Typical jobs include weak extraction at the canopy and a noisy fan that has got louder over time, across axial fans, in-line fans and centrifugal fans.

London kitchens tend to trade late and open early, so work in Aperfield is normally booked for the night or the early hours. Before the clean, we agree loading, parking and roof access with whoever manages the building.

We’ve 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.

What happens if it’s left?

A greasy fan has to work harder to move the same air. Airflow at the canopy drops and the kitchen gets hotter and smokier and the motor works harder. A busy site in Aperfield builds up dirt and wear quickly, so putting it off makes the eventual job larger.

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

What you get with us

  • Work around your opening hours, with 24/7 emergency cover
  • One number for every site across the South East and London
  • Fixed quotes, usually within one working day

What staff can safely do

Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.

Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.

What affects the quote in Aperfield

The quote reflects the site in front of us. We take into account:

  • Site rules, permits and inductions
  • The times the site is available
  • Whether we need access equipment or extra panels
  • Parking and loading at the site

Working hours, access and the scale of the site all affect the cost. We take each of them into account, and the price is fixed before we start.

What to send for a quote

Photos and a few facts are often enough to price the work. Useful things to send:

  • Detail shots of panels, filters and grilles
  • Where the site is and what kind of site it is
  • Anything you’ve noticed, such as smells, noise, drips or poor airflow
  • Wide pictures of the system and the area around it

Quoting starts with a diagnosis, either from pictures and details you send or from a site visit. Then we send a fixed price so you know the cost before work begins.

Aftercare tips

No system stays clean for ever, but care slows the build-up. A few tips:

  • Check the report shows the fan was cleaned
  • Keep the grease filters clean and in place
  • Keep records of every fan clean
  • Keep the fan on whenever the range is lit

When we’ve finished, the fan is reassembled and run. Anything we notice, like noise, vibration or a worn part, goes on the report, so you can plan any repair.

Run the fan throughout cooking. Air that keeps moving carries vapour out rather than letting it settle, so keeping it running helps keep it clean.

Different parts, different methods

Fan housings and motors

Motors and their electrics are kept dry and treated with care, and the fan is isolated throughout. Grease on and around the motor can trap heat, so the surrounding area is cleaned carefully.

Inline duct fans

An inline fan can be easy to forget because it’s out of sight. The survey makes sure it’s part of the clean.

Aperfield kitchens: local notes

Look up Aperfield on the FSA’s food hygiene register and you’ll find about 11 restaurants, cafés and works canteens and about 10 sandwich bars and takeaways in Aperfield and the streets around it, up to about 1.5 miles out. Grease builds up on fan blades and housings in kitchens like these, unbalancing the impeller. Night work suits London kitchens, and roads and loading bays tend to be quieter too. Aperfield is covered by London Fire Brigade. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.

Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Down House is about 1.7 miles north), access may need planning. A hospital like Warlingham Park Hospital, about 3.4 miles west, is the kind of site where a kitchen may cook for patients, staff and visitors all day. School kitchens, at schools like Biggin Hill Primary School for example, are typically cleaned in the holidays so no lunches are lost.

Aperfield is about 4 miles east of Warlingham, in Greater London. Sites in Aperfield get the same service as everywhere we cover: diagnosis first, a fixed price, out-of-hours working where needed and a written report with pictures. Across Greater London, we cover 764 places, and Aperfield is one of them. For sites nearby, see our London page (15 miles or so).

We cover every part of the TN16 postcode area for extract fan cleaning and the roads nearby. Whether your site is on Main Road, Haig Road and Lotus Road or anywhere close by, our technicians can take on the work. If your site is just outside Aperfield, we cover Biggin Hill (1 mile north-west), Berry's Green (1 mile north-east), Single Street (1 mile north-east), Luxted (1 mile north) and Cudham (1 mile north-east). Further out, we also cover London (15 miles north-west), Whitechapel (15 miles north), Stockwell (13 miles north-west), Orpington (6 miles north-east), Wimbledon (14 miles north-west) and Plaistow (15 miles north).

Local landmarks in Aperfield

Around Aperfield, our work takes us to kitchens and buildings near Charles Darwin School and The Old Jail Public House and the streets around them. The nearest railway station is Oxted station, roughly 4 miles south-west of the centre. Other landmarks nearby include Warlingham Park Hospital (3.4 miles west). For a walk, there’s West Kent Golf Course nature reserve and Betsom's Hill.

How the visit works

Protection comes first: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. The work on site takes an hour or two for most single fans, and the area is cleaned down before we leave. Managed blocks in London often need contractors booked in ahead, and we’re happy to deal with the agent directly for a site in Aperfield.

  1. We locate the fan and plan how to reach and isolate it.
  2. It’s isolated so it cannot run while we work.
  3. We scrape the heavy grease from the blades and housing.
  4. The fan is degreased, taking care around the motor.
  5. We reassemble, run and photograph the fan.

Getting ready for the visit

  • Find the previous report, if there is one
  • Let us know about permits to work or site inductions
  • Agree a time when the area can be out of use

When it’s something else

A few issues sit outside what this work can do:

  • A failed motor or worn bearings (that needs a fan repair or replacement)
  • Electrical faults in the fan’s supply or controls (an electrician’s job)
  • A cracked or broken impeller (it needs replacing)

If you are not sure, just call us on 0345 646 2711, or send details by email and we will give you a straight answer.
