Extract fan cleaning in Newgate Street, done properly

The extract fan is the heart of the system: it draws the air through the canopy and ductwork and pushes it outside. Whatever grease slips past the filters and duct reaches the fan and we clean it off. The work covers in-line fans, axial fans and roof-mounted fans, and common reasons people get in touch are fat spreading onto the roof or wall by the fan and a fan that has never been cleaned.

Work in a small place like Newgate Street starts with a call to agree access and timings, and the clean covers the whole system, as it would anywhere: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.

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’re fully insured.

Staff cleaning versus specialist work

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.

In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.

Newgate Street questions

Will you come out to Newgate Street?

Yes. Villages and rural sites across the South East are part of our work, Newgate Street included. Photos of the system and directions to the site help us plan the visit.

Which fire authority looks after Newgate Street?

That is Hertfordshire Fire and Rescue Service. TR19® is not law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.

How long will it take to clean the fan?

A single accessible fan does not take long, while fans on high roofs or in tight voids take longer. It’s done while the kitchen is closed.

Do you offer maintenance contracts?

Yes. Tell us what you have and how it’s used, and we’ll suggest a schedule and quote for it.

What information do you need?

A short description and a few pictures plus the address and your hours. We will ask for anything else we need.

Do you need to turn the fan off to clean it?

The fan is isolated before we open it, so it cannot run during the clean. With the extract off, the kitchen can’t cook, so we work out of hours.

Are you accredited?

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

Is the fan included in a TR19 clean?

Yes, it should be. A TR19 Grease clean covers everything from canopy to discharge, and the fan is a key part of it, so it’s cleaned too.

Why act early in Newgate Street

A fan that sounds rough in Newgate Street 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. In a small place like Newgate Street, a system that fails can take a site out of use.

We don’t list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll talk you through it.

Grease, kitchens and Newgate Street

Food Standards Agency records list about 12 cafés, restaurants and staff canteens and about 3 sandwich bars and takeaways within 1.5 miles or so of the middle of Newgate Street. Any of those kitchens with a canopy relies on a fan that gathers grease as it runs. Kitchens in Newgate Street get their food hygiene inspections from Welwyn Hatfield council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A TR19® certificate and photo report after each clean gives you a record to show an inspector. Newgate Street is covered by Hertfordshire Fire and Rescue Service. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.

If you run catering at a healthcare site, such as a hospital like Chase Farm Hospital about 4.3 miles south, the extract may need cleaning more often than a part-time kitchen. If you run a church or community hall kitchen, near Church of St Mary Ponsbourne or elsewhere in Newgate Street, its extract still collects grease from every lunch and event.

Newgate Street is about 3 miles north-west of Cheshunt, in Hertfordshire. Every kind of commercial site in Newgate Street, we can take on extract fan cleaning.

How the visit works

We start by comparing what we find with the survey or your pictures. If anything is different, we talk it through with the person on site before carrying on. From there, it takes a couple of hours per fan, depending on its size and the build-up. Rural roads and tight entrances are worth telling us about before a visit to Newgate Street.

  1. First we check the fan’s condition and how it sounds.
  2. Once isolated, we open the fan up.
  3. The impeller is cleaned blade by blade so it runs balanced.
  4. Housing, outlet and the area around the motor are cleaned.
  5. The fan goes back into service with a report on its condition.

Before we arrive

  • Let us know about permits to work or site inductions
  • Clear loose items from the work area
  • Let us know how we reach the system, including roofs, risers and plant rooms

How to get a quote

There’s no standard price list, because every site is different. We look at your system first, from pictures or on a visit, and then give you a fixed quote. To get going, phone us on 0345 646 2711 or use the quote form.

Advice

Common problems we fix in Newgate Street

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

The symptoms we’re asked about most include:

  • Thick grease on the impeller and casing
  • Weak extraction at the canopy
  • Hot, greasy smells near the fan
  • Vibration from an unbalanced impeller

Wyllyotts Manor, about 4 miles south-west, is one of the historic houses near Newgate Street; if you run event catering at a venue like that, cleans can be booked between functions.

Before you book anyone

  • What paperwork you get at the end
  • What hours they’ll be on site
  • Exactly which parts of the system are covered
  • Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor

Choosing a duct cleaning contractor

When something else is needed

A few issues sit outside what this work can do:

  • A fan that was never right for the kitchen
  • An impeller that is bent or split
  • A faulty speed controller or isolator

If in doubt, call 0345 646 2711 or use the quote form and we will say what we think before booking.

Parts of the system we cover

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

Looking after it afterwards

Good habits slow the build-up between visits. Our tips:

  • Do not store items in front of the fan’s access point
  • Keep the fan on whenever the range is lit
  • Keep each photo report with the maintenance log
  • Keep the grease filters clean and in place

When the fan is cleaned as part of a full TR19® Grease clean, a TR19 certificate is issued through the BESCA Vent Hygiene Elite portal. If only the fan is cleaned, the photo report says so.

Fewer grease particles reaching the fan means less build-up. Clean, well-seated filters are the fan’s first protection, and replace any that are damaged.

What affects the quote in Newgate Street

The survey tells us what the work involves. We look at:

  • The number of sites or systems
  • The condition of the system
  • Whether we need access equipment or extra panels
  • Whether it’s a one-off visit or part of a schedule

The cost depends on the size of the system, what state it’s in and access to every part of it. You get a fixed price before any work starts, so there are no surprises.

Asking for a quote

There’s no need for technical detail. Just send:

  • Any previous report or certificate
  • Where the site is and what kind of site it is
  • Anything you’ve noticed, such as smells, noise, drips or poor airflow
  • Where the plant sits or the system leaves the building, such as a roof or outside wall

For a fixed quote, call us on 0345 646 2711 or email us and tell us the type of site, your opening hours and roughly what the system looks like. A few pictures and your last certificate or report help a lot. We usually come back within one working day.
