Honest limits

Not every problem is solved by extract fan repair, and we’d rather say so up front. It won’t put right:

  • Wiring and supply faults beyond the fan itself
  • Cooking smells reaching neighbours, which may need odour control
  • Grease throughout the ductwork, which needs a full TR19 clean

If in doubt, phone us on 0345 646 2711 or use the quote form and we’ll say what we think before you book.

Parts of the system we cover

Extract fan repair in Forty Green

Working on a fan in Forty Green means switching the extract off first, so the job is fitted around the kitchen’s hours. We can work in the evening, overnight or at the weekend, and a fan that dies mid-service can go straight to our 24/7 line. The work covers kitchen extract fans, roof and wall fans and bearings, and common reasons people get in touch are poor airflow at the canopy and an extract fan that has stopped working.

Rural kitchens often have fans mounted on outside walls or roofs, exposed to the weather. Weather and grease together wear out motors and bearings.

A written report with pictures follows every visit, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Your questions about extract fan repair in Forty Green

Can you get to a site in Forty Green?

Yes. Villages and rural sites across the South East are part of our work, Forty Green included. Just mention lanes, gates or anything else about the site when you book.

Can you come to Forty Green after we close?

Yes, we can come after you close and finish before you open. It means the site in Forty Green keeps running as normal. Let us know the hours you are closed and we will book within them.

Why is our extract fan so noisy?

Common causes are grease on the impeller, worn bearings, slipping belts and loose mountings. Each sounds a little different and we find the exact cause on site.

Do you recommend a next date?

Yes. Every report includes a recommended date for the next visit, based on use and what we found.

Do I get a report after the visit?

Yes. You get a written report with pictures after every visit, covering the work, any areas we couldn’t access and the recommended next date. Where the work is a TR19® Grease clean, there’s also a certificate issued through the BESCA Vent Hygiene Elite portal.

What happens if you cannot reach some of it?

They’re marked on the report. In ductwork, new access panels are often the answer, and we can fit those.

Is there a survey before the work?

Yes. Every job is surveyed first, from your pictures and details, or with a visit where necessary. Then you get a fixed quote.

Who has the legal duty for fire safety?

The law calls them the responsible person. That is generally the employer or the person in control of the premises, and in shared buildings more than one person can have duties. If you are not sure, check your lease and fire risk assessment.

Keeping the system healthy

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

  • Save our number for the 24/7 emergency line
  • Do not turn the fan down to hide a noise
  • Clean or change filters on schedule
  • Note when the fan trips or cuts out

If parts have to be ordered, we tell you how the kitchen can carry on in the meantime. We then come back and fit them at a time that suits your service.

A slipping belt or a loose mount is a small job. Ignored, they can lead to bigger failures so early attention pays.

When to call us in Forty Green

Bearings wear out with heat and long hours. Worn bearings whine, rumble or grind, and if they’re left they can seize.

These are the problems we see most often:

  • A fan that whines, hums or grinds
  • A fan that keeps cutting out
  • An extract fan that has stopped working
  • A fan worn beyond sensible repair

Around Forty Green, a failed fan can be reported day or night on our 24/7 line.

Choosing a duct cleaning contractor

How we price extract fan repair

You’ll get a fixed price before work begins. It’s based on:

  • Any permits to work or inductions
  • A single visit or a regular plan
  • The condition we find in the survey
  • Whether several sites go on one quote

Combining work into one visit or one programme can make for a more efficient booking. Mention every system or site you need covered and we’ll price it together.

Helping us quote

We can often survey from photos. Try to include:

  • Any previous report or certificate
  • The site address and the type of premises
  • Close-ups of filters, grilles, hatches or access panels
  • The times we could work without disrupting the site

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

What the work involves, part by part

Roof and wall-mounted fans

Noise from an outside fan can carry beyond the kitchen. It’s often down to loose mounts or worn bearings.

Belt-driven fans

Squealing at start-up often points to a belt. We check the belt condition, tension and alignment and renew them where necessary.

For landlords and multi-site operators

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

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 can quote for the whole system.

The process

A visit follows the same order every time: protect the area, make the system safe, carry out the extract fan repair, tidy up and hand over the paperwork. On site, the work takes anything from an hour or two to a full visit, depending on the fault. A quick note on how to find the site and where to park makes a visit to Forty Green run smoothly.

  1. First, you tell us the symptoms: noise, shaking, weak extraction or no power.
  2. The fan is isolated and opened up so we can see inside.
  3. We check the motor, bearings, drive, impeller and mountings.
  4. We explain the fault and give you a fixed price for the fix.
  5. We fix or replace the fan, then test it running before we leave.

How to prepare

  • Let us know about parking and loading
  • Tell us about site rules, permits or sign-in
  • Dig out any earlier paperwork for the system

How to get a quote

The quickest way to a quote is to send photos: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and many jobs can be priced from that alone.
