About our extract fan cleaning in Sydenham

Think of the fan as the system’s heart and the grease as a clot. A heart under strain works harder for less. Our job is to clear it, check it runs smoothly and record what we found, before signing it off. The work covers in-line fans, roof-mounted fans and fan housings, and the jobs we see most are a fan that hums, whines or rumbles and less air being pulled from the kitchen.

In London, few kitchens can spare a day to close, so extract cleaning in Sydenham is normally done overnight, after the last service. Parking, loading and access to the roof are agreed with the building before the night of the clean.

The paperwork matters as much as the work. You get a written report with pictures after each visit, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

Different parts, different methods

Impellers and blades

A clean impeller shows any damage: cracks, bent blades or wear. We note any concerns.

Kitchens with long cooking hours

A long-hours kitchen cannot afford a fan failure. A clean fan is less likely to strain, and our 24/7 emergency callout is there if it happens anyway.

Common questions in Sydenham

Can the work in Sydenham be done at night or at weekends?

Yes, out-of-hours work is a big part of what we do. That way a site in Sydenham does not have to lose a day’s trading. Let us know the hours you are closed and we will book within them.

Who is the fire and rescue service for Sydenham?

It’s London Fire Brigade, which covers Sydenham. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.

Can one contract cover all our sites?

Yes. Our area covers London and the South East, so we can schedule a run of sites as one programme. Every site has its own report.

How often should the extract fan be cleaned?

Daily cooking hours set the minimum in BESA guidance. Heavy use means at least every 3 months, light use at least every 12, fan included.

Are you insured?

Yes. Duct Doctor is fully insured, and the details are available on request.

What if the fan needs more than a clean?

Anything beyond cleaning is flagged, with what we found. We offer extract fan repair and replacement, and there’s a 24/7 emergency callout for breakdowns.

How much does extract fan cleaning cost in Sydenham?

Size, condition, access and working hours all affect the cost. Call for a fixed quote, usually ready within one working day.

How long will it take to clean the fan?

Allow an hour or two for one fan, longer when it’s hard to reach. We’ll confirm the time when we quote.

Do you need extract fan cleaning in Sydenham?

The fan sits at the end of the grease’s journey. The grease that is left lands on the blades and the casing, and the spinning blades fling it onto the walls of the housing.

These are the problems we see most often:

  • Fat spreading onto the roof or wall by the fan
  • Hot, greasy smells near the fan
  • A fan coated in grease inside its housing
  • A noisy fan that has got louder over time

Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; St Christopher's Hospice is the nearest hospital to Sydenham, about within half a mile south-west.

How to choose an extract cleaning contractor

What extract fan cleaning looks like in Sydenham

The Food Standards Agency lists about 54 pubs and bars and about 5 hotels, B&Bs and guest houses as registered food businesses within roughly a mile and a half of the centre of Sydenham. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Fire safety in Sydenham falls to London Fire Brigade. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises. It’s Lewisham council that sends environmental health officers to food businesses in Sydenham. 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.

For kitchens close to Sydenham station, where the day often starts early and ends late, the extract can be cleaned overnight. If you run a church or community hall kitchen, near Church of St Bartholomew or elsewhere in Sydenham, its extract still collects grease from every lunch and event.

What staff can safely do

Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.

Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.

How the visit works

There are three stages on the day: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and pictures. The middle part takes longest, which takes an hour or two for most single fans. Security desks and permits-to-work are routine in London, so let us know what your building in Sydenham needs from us.

  1. We start by checking where the fan sits and how to isolate it.
  2. With the fan isolated, the housing is opened.
  3. The impeller and the housing around it are scraped clean.
  4. We degrease the fan and housing, taking care around the motor.
  5. We reassemble, run the fan and photograph the result.

How to prepare

  • Allow time for equipment near the work to be turned off and cool down
  • Mention any sign-in, permit or induction we need
  • Clear the space around the work

Why it’s worth doing now in Sydenham

Grease on a roof fan can also escape outside. It marks the area around the outlet and leaves more fuel outside, which is one more reason to keep it clean. Every month a London system goes without attention adds to what has to be done later.

You will not 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 drop us a line, and we will explain what it covers.

Why book with us

  • Work around your opening hours, with 24/7 emergency cover
  • One contact for all your sites in London and the South East
  • Photo reports with every job
  • A fixed price before any work starts

What affects the quote in Sydenham

Every site gets its own quote. These are the things that affect it:

  • Working hours and out-of-hours timing
  • Where the site is and how we reach it
  • A single visit or a regular plan
  • Any permits to work or inductions

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

What we need to know

You do not need the technical terms. Just send:

  • When the site is open and when it’s quiet
  • Any access panels or hatches you can see
  • Anything you’ve noticed, such as smells, noise, drips or poor airflow
  • The site address and the type of premises

To get a fixed quote, phone us on 0345 646 2711 or send us an email with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. We normally come back within one working day.

Looking after it afterwards

Here’s the after-treatment advice, in brief:

  • Report grease escaping from the fan
  • Tell us if the extract feels weaker
  • Leave a clear route to the fan
  • Make sure the fan is included each time

We take away the grease and dirty water from the fan clean. On a roof or outside wall, we leave the surrounding area tidy.

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.
