Extract fan cleaning in Thornwood Common

How we handle extract fan cleaning in Thornwood Common

Every kitchen extract depends on its fan: 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 that is what we clean. The work covers in-line fans, roof-mounted fans and centrifugal fans, and common reasons people get in touch are a fan that no longer moves enough air and rough running from the extract fan.

Rural kitchens often have long, low duct runs through a roof space or along an outside wall, where grease settles in the flat sections. Access, parking and timings are agreed before the day.

The sign-off is always in writing: a written report, dated and illustrated with pictures, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

The process

Each visit runs to the same pattern: sheeting and protection first, make the system safe, do the work, tidy up and leave you the report. On site, the work takes a few hours where there are several fans or heavy deposits. Somewhere like Thornwood Common, lanes, gates and parking are worth mentioning in advance.

  1. The fan is found and its type, access and isolation checked.
  2. We isolate the power before opening the housing.
  3. Grease is scraped off the impeller blades and casing.
  4. Blades, housing and surrounds are degreased with care around the electrics.
  5. It’s closed up, run, checked and photographed for the report.

How to prepare

  • Make sure someone can let us in and lock up afterwards
  • Move anything stored near the system
  • Let us know when the site is closed or quiet

Related advice

In-house cleaning or a specialist?

For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.

Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.

Between visits

Aftercare is simple, and it helps at the next visit:

  • Listen for new noises or vibration from the fan
  • Keep each photo report with the maintenance log
  • Check filters are seated before cooking
  • Do not store items in front of the fan’s access point

When we have finished, the fan is reassembled and run. If anything seems wrong, from vibration to wear, we note it, so you can plan any repair.

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.

Questions from Thornwood Common

Which fire authority looks after Thornwood Common?

Thornwood Common is in the area of Essex County Fire and Rescue Service. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.

Is Thornwood Common within the area you cover?

Yes, we work in villages as well as towns, and Thornwood Common is covered. Photos of the system and directions to the site help us plan the visit.

Do we need to close while you work?

Usually not. Out-of-hours visits keep the disruption down. Bigger sites can be done in stages to keep things running.

Which kinds of sites do you work on?

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

What about areas you can’t get to?

Anything we can’t reach goes on the report, with photos where possible, and we tell you what would make it reachable, for example new access panels.

Why is my extract fan noisy?

A common cause is grease. Grease collects unevenly and unbalances the impeller, causing vibration and noise. Cleaning may sort it, but worn bearings or a failing motor need a repair.

How much notice should we give?

For planned work, earlier is better, especially if the next clean or test is due soon. Emergencies are different, because our line is open 24/7.

What does extract fan cleaning cost?

Size, condition, access and working hours all affect the cost. Ask us for a fixed quote and we will usually reply within one working day.

What affects the quote in Thornwood Common

We do not publish a price list, because sites vary so much. What we look at:

  • Whether it’s a one-off visit or part of a schedule
  • Where the site is and how we reach it
  • When the work can happen, such as evenings, overnight or weekends
  • Access, including roofs, risers and ceiling voids

The price reflects the work, not guesswork. That is why every job is surveyed first, and why the quote is fixed before any work starts.

Helping us quote

To help us quote quickly, please include:

  • Your opening hours and when the area is out of use
  • Any symptoms, from odd noises to smells or leaks
  • How we’d reach plant on a roof or in a plant room
  • The site address and the type of premises

Quoting starts with a diagnosis, either from photos and details you send or from a site visit. After that, you get a fixed price for the work, before work begins.

  • A failed motor or worn bearings (that needs a fan repair or replacement)
  • A dirty duct upstream of the fan
  • A fan that was never right for the kitchen

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

Grease, kitchens and Thornwood Common

Food Standards Agency data counts about 8 restaurants, cafés and canteens across Thornwood Common and its immediate surroundings (about a mile and a half). The fan at the end of each of those extracts collects grease that slows it and wears the motor. Food hygiene inspections in Thornwood Common are the job of Epping Forest council’s environmental health team. Extraction counts as kitchen equipment, so its condition can come up on the day. A dated certificate in the maintenance file answers the question before it’s asked. Thornwood Common is covered by Essex County Fire and Rescue Service. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract.

If your kitchen is in a listed or historic building, like the houses around Thornwood Common (Hill Hall is about 3.3 miles south), fitting access panels needs care. For schools such as St John's Church of England Voluntary Controlled School, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed.

Why act early in Thornwood Common

A greasy fan has to work harder to move the same air. Less air is pulled from the kitchen, so heat and smoke linger, while the motor runs under more strain. In a small place like Thornwood Common, a system that fails can take a site out of use.
