Extract fan cleaning for kitchens and businesses in Patchetts Green

Think of the fan as the system’s heart and the grease as a clot. A greasy fan works harder and moves less air. We clean it, run it and note anything that needs a closer look so you get a clean bill of health. If you are dealing with a fan that no longer moves enough air and grease escaping from the fan outlet, we can put it right.

For a kitchen in or near Patchetts Green, the visit is planned around opening hours and the journey, and the clean itself is the same full TR19® job as in any town: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.

Every visit ends with a written report and pictures, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

How we price extract fan cleaning

The diagnosis comes before the price. We look at:

  • The number of sites or systems
  • The condition of the system
  • The scale of the work
  • Site requirements such as sign-in and permits

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

What to send for a quote

Photos let us diagnose from a distance. The most useful are:

  • Where the site is and what kind of site it is
  • The roof, plant room or outside wall the system runs to
  • Close-ups of filters, grilles, hatches or access panels
  • The times we could work without disrupting the site

We don’t publish a price list, because every site is different. Instead, we look at your site first, from photos or a survey, then send a fixed quote. To get going, phone us on 0345 646 2711, or send details by email.

Common questions in Patchetts Green

Can you work in Patchetts Green outside opening hours?

Yes, nights and weekends are routine for us. The work in Patchetts Green can fit around your hours. When you call 0345 646 2711 or drop us a line, mention when the site is quiet.

Do you work in villages like Patchetts Green?

Yes. Patchetts Green is within the area we cover across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

How much notice do you need?

It depends on the time you need and how big the job is. Tell us your preferred dates when you ask for a quote, and for anything urgent, ring our 24/7 emergency line.

Why has my extract fan got louder?

Often it’s grease on the impeller. Grease collects unevenly and unbalances the impeller, causing vibration and noise. If cleaning does not, the bearings or motor may need attention.

Do you survey before quoting?

Yes. We always survey first, either from photos and details you send or on a site visit. Then you get a fixed quote.

Is TR19 a legal requirement?

No. The law sets the duty, and TR19® is the recognised benchmark for meeting it. Under the Fire Safety Order 2005, the responsible person must reduce fire risk, and many insurers can refuse or reduce a claim without proof of cleaning.

What do you need from me for a quote?

A short description and a few photos, with the address and opening hours. If we need more, we will ask.

What paperwork do I get after a fan clean?

Before and after pictures go into a report, along with notes on the fan’s condition. For a full TR19 clean, you also get a certificate through the BESCA Vent Hygiene Elite portal.

Staff cleaning versus specialist work

For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.

Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.

When it’s something else

We will always give you a straight diagnosis, so here’s what this work cannot put right:

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

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

Where we work

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

Multi-site and managed buildings

Facilities teams in offices, schools and healthcare sites book us too in Patchetts Green and across Hertfordshire. Larger estates can be phased building by building to keep disruption down.

For anyone managing more than one site, we can plan visits across the whole estate and price them together. Every building has its own written report, so each one has its own record.

The process

We are used to working while the site is closed. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. The visit itself 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 Patchetts Green.

  1. First we check the fan’s condition and how it sounds.
  2. With the fan isolated, the housing is opened.
  3. The impeller is cleaned blade by blade so it runs balanced.
  4. We clean the casing, the outlet and around the motor.
  5. We run the fan and note its condition in the photo report.

Before we arrive

  • Mention any parking or loading restrictions
  • Make sure equipment near the work can be switched off and left to cool
  • Clear the space around the work

Advice

What we’re called out for in Patchetts Green

How fast a fan gets greasy in Patchetts Green depends on the cooking: how many hours a day the kitchen runs and what it cooks. BESA guidance sets minimum intervals of 3, 6 or 12 months for the whole system by daily use.

Keep an eye out for any of the following:

  • A fan shaking on its mounts
  • Less air being pulled from the kitchen
  • Grease around the motor and its mounts
  • Grease escaping from the fan outlet

Where a hall near Church of St John the Baptist, or anywhere in Patchetts Green, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

Questions to ask before booking

  • If the quote is a fixed price or an estimate
  • Whether a survey comes first
  • Whether they recommend a next date
  • What happens if part of the system cannot be accessed

Choosing a duct cleaning contractor

Between visits

A little care between visits keeps the system in better shape. We recommend:

  • Book the fan into every full TR19 clean
  • Do not store items in front of the fan’s access point
  • Flag smoke lingering at the canopy
  • Keep the fan on whenever the range is lit

A full system clean includes a TR19 certificate from the BESCA Vent Hygiene Elite portal. A fan-only clean is recorded in the photo report.

Run the fan throughout cooking. Grease settles faster when the air stops moving, so keeping it running helps keep it clean.

Grease, kitchens and Patchetts Green

There are about 26 restaurants, cafés and works canteens and about 9 takeaways and sandwich shops across Patchetts Green and its immediate surroundings (about a mile and a half), according to the Food Standards Agency’s register. Each kitchen extract among them ends at a fan, and grease on the impeller strains the motor. In Patchetts Green, food businesses are inspected by environmental health officers from Hertsmere council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Our report lists what was cleaned and when, which is useful to have ready. Hertfordshire Fire and Rescue Service covers Patchetts Green. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.

If your kitchen is in a listed or historic building, like the houses around Patchetts Green (High Elms Manor is about 3 miles north-west), fitting access panels needs care. A hospital like Watford General Hospital, about 2.5 miles south-west, is the kind of site where a kitchen may cook for patients, staff and visitors all day.
