Extract fan cleaning across Woodhall Farm

How we handle extract fan cleaning in Woodhall Farm

Every kitchen extract depends on its fan: 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 fan housings, axial fans and centrifugal fans, and people most often call us about an extract fan that vibrates or rattles and grease stains around the discharge.

Around a smaller place like Woodhall Farm, kitchen extracts tend to belong to pubs, cafés, takeaways and school or care home kitchens. A kitchen that cooks fewer hours still builds up grease, so cleaning is planned around how much it cooks and what the readings show.

It’s worth checking any contractor’s accreditations. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Between visits

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

  • Don’t store items in front of the fan’s access point
  • Flag smoke lingering at the canopy
  • Keep the grease filters clean and in place
  • Don’t turn the fan off mid-service

The area around the fan is left clean, with waste grease removed. On a roof or outside wall, we leave the surrounding area tidy.

Listen to the fan. Rattles, hums or shaking can be early signs of build-up or wear, and catching it early keeps it a cleaning job.

When it’s something else

We’d rather tell you now than book work that won’t help, so these are the things it will not cover:

  • A dirty duct upstream of the fan
  • A faulty speed controller or isolator
  • A failed motor or worn bearings (that needs a fan repair or replacement)

If you are not sure, just ring 0345 646 2711, or email photos and we will give you a straight answer before you book.

Where we work

  • Roof-mounted fans
  • Axial fans
  • Discharge points

Common questions in Woodhall Farm

Do you cover smaller places like Woodhall Farm?

Yes, Woodhall Farm is part of our area, however small the site. The journey is planned ahead, so a few details about the route help.

Can you work in Woodhall Farm outside opening hours?

Yes, evening, overnight and weekend work is normal for us. It means the site in Woodhall Farm keeps running as normal. Just call 0345 646 2711 or email us with your opening times and we will plan around them.

Will we have to shut during the visit?

Normally not. Booking the work out of hours means the site can carry on as normal. Larger jobs can be phased over several visits to keep things running.

Do you work with multi-site operators?

Yes. Our area covers London and the South East, so sites at different addresses can be planned together on one programme. Every site has its own report.

How much does extract fan cleaning cost?

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

Can you fix a fan that’s worn out?

We also repair and replace extract fans. If cleaning shows a worn motor, bearings or impeller, we will tell you and quote for the repair.

Is the fan isolated during cleaning?

The fan must be isolated, for safety. We clean out of hours, in the evening, overnight or at weekends, so cooking isn’t affected.

Do you have insurance?

Yes. Duct Doctor is fully insured, and we can share the details when you need them.

Different parts, different methods

Inline duct fans

Space around an inline fan can be tight, so the method is planned in advance. If it cannot be reached fully, the report says so.

Impellers and blades

Grease on the leading edges of the blades cuts the fan’s efficiency. Scraping and degreasing them restores their shape, so the fan can run as intended.

What happens if it’s left?

A fan that sounds rough in Woodhall Farm is often telling you the extract needs a clean. If the fan is coated, the duct before it usually is too, so it’s worth checking the whole system. It’s easy to lose track of when the work was last done on a quieter site.

Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we will go through it with you.

The process

There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Afterwards, the area is left tidy and the written report follows. Evenings, weekends or a closed day all work for a site in a place like Woodhall Farm.

  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. Housing, outlet and the area around the motor are cleaned.
  5. We run the fan and note its condition in the photo report.

How to prepare

  • Tell us where we can park and unload
  • Make sure equipment near the work can be switched off and left to cool
  • Find the previous report, if there is one

Getting a quote

Quoting starts with a diagnosis, either from pictures and details you send or from a site visit. Then we send a fixed price, before we start.

Related advice

In-house cleaning or a specialist?

Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.

Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.

Fixed quotes for extract fan cleaning in Woodhall Farm

Some jobs are bigger than they look, and some smaller. The main factors:

  • When the work can happen, such as evenings, overnight or weekends
  • Access, including roofs, risers and ceiling voids
  • Parking and loading at the site
  • How many systems or sites are involved

Several systems or sites on one quote can make for a more efficient booking. Tell us about everything you’d like looked at, and you’ll get one fixed quote.

Helping us quote

Before you ask for a quote, gather:

  • Any access panels or hatches you can see
  • Where the plant sits or the system leaves the building, such as a roof or outside wall
  • Any symptoms, from odd noises to smells or leaks
  • The site address and the type of premises

Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, the quote is fixed before any work is booked.
