Extract fan repair for kitchens and businesses in Hanworth
We treat a failing fan much like a patient: listen to it, diagnose the fault, then treat it. The aim is steady, quiet extraction and a plain account of what we found. If you’re dealing with a whining or grinding extract motor and a worn or slipping fan belt, we can help, from kitchen extract fans, bearings and fan housings onwards.
Rooftop fans in London take the weather as well as the grease from below, and bearings, belts and motors wear out in the end. A fan that’s noisy or vibrating is giving a warning.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

What the work involves, part by part
Impellers and housings
The impeller does the work of moving air through the system. Grease on it throws it out of balance and cause vibration.
Direct-drive fans
Grease on the impeller unbalances a direct-drive fan quickly. Cleaning it can cure the noise as long as the bearings are still sound.
When it’s something else
Not every problem is solved by extract fan repair, and we’ll tell you before any work starts. It will not put right:
- A system that needs redesigning rather than repairing
- Grease throughout the ductwork, which needs a full TR19 clean
- Problems with the gas supply or its interlock valve
Not sure which it is? You can phone us on 0345 646 2711 or drop us a line and we will tell you honestly.

Your questions about extract fan repair in Hanworth
Which environmental health team covers Hanworth?
That is Richmond-Upon-Thames council, whose environmental health officers carry out food hygiene inspections in Hanworth. If the extract fan has failed, it’s worth having the repair booked, and the details to hand, before an officer visits.
Do you cover Hanworth for emergency fan repairs?
Extract fan emergencies in Hanworth are covered around the clock. Phone 0345 646 2711 and we will talk through the fault and access. Details of the make and model help us plan the repair.
Why is our extract fan so noisy?
Noise normally comes from grease build-up, bearings, belts or loose fixings. Each sounds a little different and we find the exact cause on site.
Do you provide a certificate or report?
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. Kitchen extract cleans to TR19® Grease also get a certificate through the BESCA Vent Hygiene Elite portal.
Can one contract cover all our sites?
Yes. Tell us the addresses and what each needs and we’ll quote them together.
Is there a survey before the work?
Yes. We always survey first, from your pictures and details, or with a visit where needed. A fixed quote follows.
Do we lose a day’s trading?
Not usually. We need the work area to ourselves while we are on site, so we book a time when it would be closed anyway.
How far ahead should we book?
Book as early as you can for planned work, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.

Other services in Hanworth
Do you need extract fan repair in Hanworth?
Fan bearings do not last for ever, especially in a hot, greasy airstream. As they wear, you hear a whine or a rumble, and if they’re left they can seize.
The symptoms we are asked about most are:
- A fan that whines, hums or grinds
- A fan shaking on its mountings
- An old fan that needs replacing
- An extract fan that has stopped working
If you run a church or community hall kitchen, near St Richard's Church or elsewhere in Hanworth, an extract fan that rarely runs can seize or fail when it’s needed.
Before you book anyone
- Which accreditations they hold, and whether you can check them
- Whether VAT is included
- If they look at the system before pricing
- What hours they’ll be on site
For landlords and multi-site operators
Whether it’s one building or many, you get the same standard: a survey first, a fixed quote, the work timed around the site and a report with pictures.
Facilities teams in offices, schools and healthcare sites book us too in Hanworth and across Greater London. Larger estates can be phased building by building around the people who use them.
What affects the cost of extract fan repair
We quote each job individually. This is what makes a difference:
- Whether we need access equipment or extra panels
- The number of sites or systems
- The times the site is available
- How big the system is
Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered and we’ll price it together.
Helping us quote
A few details help us quote accurately. When you get in touch, it helps to send:
- Where the site is and what kind of site it is
- The paperwork from the last visit, if you have it
- How we’d reach plant on a roof or in a plant room
- Wide photos of the system and the area around it
For extract fan repair in Hanworth, call 0345 646 2711, or send details by email. Let us know the site type and the opening hours, and send pictures or your last report if you can. A fixed quote usually follows within one working day.
Extract fan repair around Hanworth
There are about 57 restaurants, cafés and canteens and about 25 sandwich bars and takeaways in Hanworth and the streets around it, up to about 1.5 miles out, according to the Food Standards Agency’s register. A kitchen with a dead extract fan gets hot and smoky fast, and kitchens like these feel it at once. In London, a fan on a roof or in a basement can take planning to reach, with parking and loading to arrange. Environmental health officers from Richmond-Upon-Thames council inspect food businesses in Hanworth. A kitchen with no working extract can fall short of the suitable and sufficient ventilation food hygiene rules expect. That’s one more reason not to keep cooking with a broken fan.
If you manage a school such as Buckingham Primary School and the kitchen fan is getting louder, the next break is the time to deal with it.

What happens on the day
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 before we start, and floors and nearby surfaces are sheeted. The work itself takes a few hours on site, depending on the fault and the access to the fan. Security desks and permits-to-work are routine in London, so let us know what your building in Hanworth needs from us.
- We start with the symptoms, such as rattling, humming, slow running or a fan that won’t start.
- The fan is isolated and opened up so we can see inside.
- Each part is checked in turn: motor, bearings, drive, impeller and fixings.
- You get our diagnosis and a fixed quote to repair or replace.
- The repair or replacement is carried out and the fan is run and checked.
Preparing for the visit
- Tell us the best time to work, such as after service or at a weekend
- Have your last certificate or report to hand
- Let us know about parking and loading
Ask for a quote
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.

Keeping the system healthy
No system stays clean for ever, but care slows the build-up. A few tips:
- Report new noises from the fan early
- Make sure every filter is in place and clean
- Don’t turn the fan down to hide a noise
- Do not cook with gaps in the filter bank
Listen to the fan over the next few weeks. If anything changes, let us know rather than waiting for it to fail.
A fan that is starting to make noise is giving you a warning. Booking a check at this stage keeps it a planned job instead of a breakdown at the worst moment.
