Advice
Extract fan repair for kitchens and businesses in Kings Langley
Extract fan repair starts with a diagnosis. Noise can come from grease on the impeller, worn bearings or a slipping belt, while a fan that won’t start may have a motor or control fault. We explain the problem, and what it will take, before work begins. If you have poor airflow at the canopy and an overheating extract motor, we can help, from fan motors, belts and pulleys and kitchen extract fans onwards.
A callout to a place like Kings Langley is planned so the first visit fixes as much as possible, based on what you tell us about the fan.

Staff cleaning versus specialist work
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That’s our job.
Keeping the system healthy
Once we’ve finished, these simple steps help:
- Tell us about a new rattle or whine straight away
- Make sure every filter is in place and clean
- Keep access to the fan controls unobstructed
- Keep the fan on a planned cleaning cycle
If the fan had grease on it, the rest of the system almost certainly does too. We can book a TR19® clean of the whole extract, with a certificate and photo report.
A scheduled maintenance plan keeps the whole system on a regular cycle, so the fan is looked at as part of each visit and wear is caught earlier.
Leave it or put it right?
Left alone, vibration spreads its damage. It loosens fixings, strains duct connections and wears the housing, so a small repair can grow into a bigger one. A quieter site near Kings Langley still needs its system looked after.
Every site is different, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all make a difference.

A kitchen with a dead extract fan gets hot and smoky fast, and kitchens like these feel it at once.

Kings Langley questions
Do you work at weekends in Kings Langley?
Yes, evening, overnight and weekend work is normal for us. Your customers, staff or residents in Kings Langley needn’t be disturbed. Your opening times are the first thing we ask for.
Which environmental health team covers Kings Langley?
In Kings Langley, it’s Dacorum council that carries out food hygiene inspections. If the extract fan has failed, it’s worth having the repair booked, and the details to hand, before an officer visits.
What accreditations do you have?
We’re 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 is TR19?
TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Can you repair a fan rather than replace it?
That depends on what we find. After diagnosing, we explain whether it can be repaired and quote a fixed price for the option you choose.
Can you supply and fit a replacement fan?
We do. A replacement is matched to the system it’s going into with a fixed price agreed before work begins.
What will a fan repair or replacement cost?
The price depends on the diagnosis. Once we have looked at it, you get a fixed quote for whichever option you choose.
Do we need to close while you work?
Usually not. Booking the work out of hours means the site can carry on as normal. Larger jobs can be phased over several visits so parts stay in use.

When to call us in Kings Langley
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.
Clients normally contact us when they notice something like this:
- An overheating extract motor
- An extract that vibrates through the ductwork
- A fan that whines, hums or grinds
- A knocking noise from the extract fan
School kitchens cannot easily serve lunch without extraction, so if you look after one at a school like Kings Langley Primary School, fix a failing fan before term starts.
