- A fan rattling in its housing
- A humming noise from the fan motor
- Vibration spreading from the fan into the ducts
Extract fan repair in Alperton
Grease is hard on extract fans. A coated impeller spins unevenly and the vibration wears out bearings and fixings. That is why we check the grease whenever we work on a fan and can arrange a TR19® clean of the whole system at the same time. If you have a knocking noise from the extract fan and a fan that won’t start at all, we can put it right, from bearings, fan motors and fan housings onwards.
London extract fans often sit on rooftops, exposed to the weather as well as the grease, and in time, bearings, belts and motors fail. Noise and vibration are worth reporting before the fan stops.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

What happens on the day
There are three stages on the day: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with photos. Most of the time goes on the work itself, which takes an hour or two to diagnose, then longer if parts or a new fan are needed. If your building in Alperton has sign-in rules, permits or key holders, mention them when you book.
- We take details of the symptoms and book a time that suits the kitchen.
- We isolate the fan before touching it.
- We diagnose the fault, checking the controls as well as the fan.
- You get a fixed price for putting it right.
- The work is done and the fan is tested running.
Before we arrive
- Mention any sign-in, permit or induction we need
- Clear the space around the work
- Agree a time when the area can be out of use

Advice
What extract fan repair looks like in Alperton
Food Standards Agency records list about 276 cafés, restaurants and staff canteens and about 207 sandwich bars and takeaways within about 1.5 miles of central Alperton. For any of them with a canopy, the extract fan is what keeps the kitchen usable. Environmental health officers from Brent council inspect food businesses in Alperton. Under food hygiene rules, a kitchen needs suitable and sufficient ventilation. A kitchen without a working fan has a problem to fix quickly. We ask about access first for a London fan job, because roofs and basements need planning.
If you run a church or community hall kitchen, near St James Church Alperton or elsewhere in Alperton, an extract fan that rarely runs can seize or fail when it’s needed. For school kitchens, at schools like Alperton Community School for example, a planned fan repair in the holidays avoids losing lunches in term time.

Why it’s worth doing now in Alperton
Where the cooking gas supply is interlocked with the extract, a failed fan can stop the kitchen cooking. Without extraction, the heat and fumes build up fast and fixing the fan early avoids a forced shutdown. Choosing the date yourself beats having a fault choose it for you.
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’ll explain each part.

Looking after it afterwards
Think of this as the after-treatment advice, short and simple:
- Keep the area around the fan controls clear
- Clean or change filters on schedule
- Never run the extract with filters missing
- 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. The fan is completed on a return visit outside your busiest hours.
Noise is usually the first sign of a fan problem. Booking a check at this stage keeps it a planned job rather than an emergency during service.
Common problems we fix in Alperton
Fan bearings do not last for ever, especially in a hot, greasy airstream. As they wear, you hear a whine or a rumble and a seized bearing stops the fan.
Keep an eye out for these warning signs:
- An extract fan that rattles or knocks
- Weak extraction and a smoky kitchen
- An overheating extract motor
- A humming noise from the fan motor
If you run a kitchen close to Wembley Central station and the extract fan is getting noisy, a planned repair after closing beats a breakdown at the rush.

Part by part
Motors and bearings
A grinding or rumbling noise often means worn bearings. We diagnose whether it’s the bearings or the motor itself before recommending a fix.
Fan controls
Where the fault is in the building’s electrical supply, an electrician is needed. If that is the cause, we will say so and explain what we found.

How we price extract fan repair
The quote reflects the site in front of us. We take into account:
- The condition we find in the survey
- Travel, parking and unloading
- Working hours and out-of-hours timing
- The number of sites or systems
We do not list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll explain what it covers.
What to send for a quote
When you call or email, it’s useful to have:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Any previous report or certificate
- Your opening hours and when the area is out of use
- The postcode and the type of business
Here’s what helps us quote: where the site is, what it is and its opening hours, a few pictures and the last certificate or report, if there is one. Then give us a ring on 0345 646 2711 or drop us a line.
Staff cleaning versus specialist work
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
Alperton: your questions answered
Does London parking affect a job in Alperton?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. Much of our London work is done overnight, which helps.
Who carries out food hygiene inspections in Alperton?
Food hygiene inspections in Alperton are carried out by Brent council. A note of when the fan failed and when it was fixed shows the problem was dealt with.
Is repair an option before replacing the whole fan?
Often, yes. Many faults are fixed by cleaning the impeller or renewing worn parts and we only recommend replacement when repair does not make sense.
Will you tell us when the next visit is due?
Yes. How often depends on use and condition, and we explain the reasoning on the report.
Can you look after several sites?
Yes. Our area covers London and the South East, so we can schedule a run of sites as one programme. Every site has its own report.
What causes a noisy extract fan?
Noise usually comes from grease build-up, bearings, belts or loose fixings. Each sounds a little different, and we diagnose it on site.
Do you cover Alperton?
Yes. We work in Alperton and across Greater London, as part of our work across South East England and London. To book, phone us on 0345 646 2711, or email photos.
Which kinds of sites do you work on?
All kinds of commercial and public premises: kitchens, offices, schools, healthcare, retail, leisure and food production. We fit the work around how the site operates.
