Extract fan cleaning near Bow

Extract fan cleaning for kitchens and businesses in Bow

The extract fan is the heart of the system: it draws the air through the canopy and ductwork and pushes it outside. Grease that gets past everything else ends up on its blades and housing and we clean it off. The work covers discharge points, in-line fans and centrifugal fans, and common reasons people get in touch are an extract fan with no cleaning record and a fan motor running hot under a coat of grease.

In London, few kitchens can spare a day to close, so extract cleaning in Bow is typically done overnight, after the last service. Before the clean, we agree loading, parking and roof access with whoever manages the building.

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

Keeping the system healthy

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

  • Check filters are seated before cooking
  • Report rattles or humming early
  • Run the extract throughout cooking
  • Keep each photo report with the maintenance log

We take away the grease and dirty water from the fan clean. Wherever the fan is, the area around it is cleaned down.

Fewer grease particles reaching the fan means less build-up. Keep the grease filters clean, fitted and in place, and replace any that are damaged.

Managing agents and facilities teams in Bow

Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we are happy to quote for all of it.

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 process

Your staff do not need to do much on the day. A contact on site lets us in at the agreed time and points us to the system, and we take it from there. Afterwards, the area is left tidy and the written report follows. Getting kit into a London building takes planning, so let us know where we can load and park in Bow.

  1. We locate the fan and plan how to reach and isolate it.
  2. We isolate the power before opening the housing.
  3. Grease is scraped off the impeller blades and casing.
  4. The fan is degreased, taking care around the motor.
  5. It’s closed up, run, checked and photographed for the report.

How to prepare

  • Let us know about permits to work or site inductions
  • Clear loose items from the work area
  • Name a contact who can let us in at the agreed time

Bow: your questions answered

Does London parking affect a job in Bow?

We plan it in advance, so let us know about loading bays, permits and access rules at the building. Night visits tend to make loading easier on London streets.

Do you work at weekends in Bow?

Yes, evening, overnight and weekend work is normal for us. That way a site in Bow does not have to lose a day’s trading. Your opening times are the first thing we ask for.

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 carry full insurance.

Who is the responsible person?

The law calls them the responsible person. It’s normally the employer, or whoever controls the building, and in shared buildings more than one person can have duties. Your lease and fire risk assessment should make it clear.

Do you cover Bow?

Yes. We cover Bow and the rest of Greater London, within our South East and London area. To book, call 0345 646 2711, or email photos.

What does TR19 mean?

It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.

Are you insured?

Yes, we’re fully insured. CHAS and SafeContractor accreditation sit alongside it, for sites that check contractor safety.

Do you have a 24/7 line?

Yes, 24/7. Office hours are Monday to Friday, 8am to 6pm, and the emergency line covers the rest.

How the job changes from site to site

Kitchens with long cooking hours

Kitchens that cook 12 to 16 hours a day put the most grease through their fans. BESA guidance sets at least 3-monthly cleaning for that level of use, fan included.

Inline duct fans

Inline fans can be in tight spaces, so the method is planned in advance. Anything out of reach is recorded.

Grease, kitchens and Bow

The Food Standards Agency lists about 84 pubs, bars and clubs and about 17 hotels and B&Bs as registered food businesses in Bow and the streets around it, up to about 1.5 miles out. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. Environmental health officers from Tower Hamlets council inspect food businesses in Bow. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Before-and-after pictures from each clean are a simple way to show the extract is in hand. Night work suits London kitchens, and roads and loading bays tend to be quieter too.

If you run catering at a healthcare site, such as a hospital like St Clement's Hospital about within half a mile south, the extract may need cleaning more often than a part-time kitchen. If you run a church or community hall kitchen, near St Paul Old Ford or elsewhere in Bow, its extract still collects grease from every lunch and event. School kitchens, at schools like Old Ford Primary - A Paradigm Academy for example, are normally cleaned in the holidays so no lunches are lost.

How we price extract fan cleaning

Before we fix a price, we need to know a few things. We check:

  • How many systems or sites are involved
  • Where the site is and how we reach it
  • The size of the system
  • Whether it’s a one-off visit or part of a schedule

The cost depends on how big the system is, the condition it’s in and access to every part of it. You get a fixed price before work begins, so there are no surprises.

Asking for a quote

When you call or email, it’s useful to have:

  • Where the plant sits or the system leaves the building, such as a roof or outside wall
  • Your opening hours and when the area is out of use
  • 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, from your photos and details or, where that isn’t enough, a survey on site. Then we send a fixed price, before any work starts.

Why act early in Bow

For a kitchen in Bow, a noisy, greasy fan is often the first sign the whole system is overdue. If the fan is coated, the duct before it typically is too so a full TR19 clean may be due. In Bow, a planned overnight visit is much easier than closing unexpectedly.

You won’t find a price list here, because each job is priced on what it involves. For a fixed quote, phone us on 0345 646 2711 or email us, and we will talk you through it.

When it’s something else

To be straight with you, some problems need a different fix:

  • A fan that’s too small for the system (a design question)
  • Grease in the duct and canopy before the fan (those need a full TR19 clean)
  • Damaged fan blades

If you’re not sure, just give us a ring on 0345 646 2711 or use the quote form and we will give you a straight answer before booking.
