About our extract fan repair in Dippenhall
Grease and fans do not mix. Deposits on the impeller throw it out of balance, which shakes the bearings and mountings. That’s why we check the grease whenever we work on a fan, and a full TR19® clean can be booked alongside. The work covers fan housings, roof and wall fans and fan motors, and common reasons people get in touch are a dead fan motor and a humming noise from the fan motor.
A callout to a small place like Dippenhall goes better when we know what we are looking at: pictures of the fan, its rating plate and how to reach it all help.
The sign-off is always in writing: a written report, dated and illustrated with pictures, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

What we do, step by step
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool first, and the area around the work is covered and protected. The work itself takes an hour or two to diagnose, then longer if parts or a new fan are needed. A quick note on how to find the site and where to park makes a visit to Dippenhall run smoothly.
- We ask what the fan is doing, from noise and vibration to a full stop.
- With the fan safely isolated, we open it up for a proper look.
- Each part is checked in turn: motor, bearings, drive, impeller and fixings.
- You hear what’s wrong and what it will cost, with a fixed quote, before we go ahead.
- The repair or replacement is carried out and the fan is run and checked.
Preparing for the visit
- Agree a time when the area can be out of use
- Make sure someone can let us in and lock up afterwards
- Let us know about parking and loading

Advice
Dippenhall questions
Who carries out food hygiene inspections in Dippenhall?
Kitchens in Dippenhall are inspected by Hart council’s environmental health officers. A note of when the fan failed and when it was fixed shows the problem was dealt with.
Can you work in Dippenhall outside opening hours?
Yes, out-of-hours work is a big part of what we do. It means the site in Dippenhall keeps running as normal. Your opening times are the first thing we ask for.
Are you insured?
Yes. Duct Doctor is fully insured, and we can share the details when you need them.
How long will the fan be out of action?
It depends on the fault, but most jobs take anything from an hour or two to a full visit, depending on the fault. You’ll know more once we’ve found the fault.
What’s TR19?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t law, but it’s the benchmark.
Can you look after several sites?
Yes. Tell us the addresses and what each needs and you will get one fixed quote.
Will I get paperwork for my records?
Yes, always. It’s a dated, written report with pictures, plus a certificate via the BESCA Vent Hygiene Elite portal for TR19® Grease cleans. Keep it in your maintenance log.
Can you come out in an emergency?
Yes. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line and we’ll talk you through the next steps.
Extract fan repair around Dippenhall
The FSA’s food hygiene register shows about 7 restaurants, cafés and works canteens within roughly a mile and a half of the centre of Dippenhall. A kitchen with a dead extract fan gets hot and smoky fast, and kitchens like these feel it at once. Dippenhall is about 37 miles from central London, well within the area we cover across London and the South East. A survey and a fixed quote come first, then the visit at a time that suits you. Food hygiene inspections in Dippenhall are the job of Hart council’s environmental health team. Under food hygiene rules, a kitchen needs suitable and sufficient ventilation. That is one more reason not to keep cooking with a broken fan.
Holidays are the time to replace a tired kitchen fan at schools such as Potters Gate CofE Primary School, rather than mid-term.

When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party and send the paperwork to whoever needs it.
Common problems we fix in Dippenhall
Fixings and anti-vibration mounts work loose or perish over time. Then every vibration is passed into the duct and the building, which is where knocking and rattling often come from.
If you notice any of these, it’s worth a diagnosis:
- Poor airflow at the canopy
- An old fan that needs replacing
- A knocking noise from the extract fan
- A dead fan motor
Hall kitchens near St Francis, or anywhere around Dippenhall, often use their fans only now and then, and an idle fan can stick.
Questions to ask before booking
- What paperwork you get at the end
- Whether the quote is based on a survey or photos
- When the next visit should be, and why
- What hours they’ll be on site
Looking after it afterwards
No system stays clean for ever, but care slows the build-up. Our tips:
- Get a noisy fan checked rather than slowed down
- Never run the extract with filters missing
- Make sure the fan is cleaned with the rest of the system
- Keep access to the fan controls unobstructed
Before we leave, the fan is run and checked. We explain the fault and the fix along with anything else that needs watching.
The fan is part of every full TR19 clean. Keeping grease off the impeller is one of the simplest ways to protect it and that means less wear.

What else we do in Dippenhall
What your team can do, and what needs us
Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.

Your quote is based on your site. We consider:

- Whether it’s a one-off visit or part of a schedule
- The scale of the work
Combining work into one visit or one programme can make for a more efficient booking. Tell us about everything you’d like looked at, and you’ll get one fixed quote.
Asking for a quote
What to send for a quote:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Wide photos of the system and the area around it
- The postcode and the type of business
- The times we could work without disrupting the site
We do not publish a price list, because every site is different. Instead, we look at your site first, from photos or a survey, and then send you a fixed quote. To get going, call 0345 646 2711 or drop us a line.
What the work involves, part by part
Fan controls
Speed controllers and isolators sit between the supply and the fan. A control fault can leave the fan dead or stuck at one speed.
Motors and bearings
A grinding or rumbling noise often means worn bearings. We find out whether the bearings or the motor is at fault and then recommend the fix.
