How we handle extract fan repair in Wealdstone
Everything a kitchen extract does depends on the fan. Once it turns noisy, sluggish or stops altogether, the cooking area soon fills with heat and fumes. We find out why and put it right, by repairing the fan or replacing it. Typical jobs include an extract fan that has stopped working and a failed fan that needs a replacement, across fan motors, kitchen extract fans and fan housings.
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.
Nothing is signed off by word of mouth: 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. Any parts we couldn’t reach are recorded on it too.

What extract fan repair can’t fix
A few issues sit outside what this work can do:
- Odour complaints that need filtration rather than a fan repair
- Problems with the gas supply or its interlock valve
- A greasy canopy and duct that a fan repair will not touch

In-house cleaning or a specialist?
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Looking after it afterwards
Here’s the after-treatment advice, in brief:
- Make sure every filter is in place and clean
- Do not cook with gaps in the filter bank
- Make sure the fan is cleaned with the rest of the system
- Make sure staff know who to call if the fan fails
Once the fan is running smoothly, keep the filters clean. Less grease on the impeller means less wear and the quieter it runs.
A slipping belt or a loose mount is a small job. Left for months, they can damage the motor or bearings so early attention pays.
Signs you need extract fan repair in Wealdstone
Some grease always slips past the filters and reaches the fan. It builds up on the impeller blades unevenly, and an unbalanced impeller shakes and starts to vibrate and rattle.
Common reasons sites call us include:
- A fan worn beyond sensible repair
- An extract fan that rattles or knocks
- A worn or slipping fan belt
- Weak extraction and a smoky kitchen
If you run a café or takeaway near Harrow & Wealdstone station, a failed fan in the middle of service is exactly what our 24/7 emergency line is for.

The process
There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and the rest is down to us. Afterwards, the area is left tidy and the written report follows. Security desks and permits-to-work are routine in London, so let us know what your building in Wealdstone 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.
- The impeller, bearings, belts or drive, motor and mounts are all inspected.
- 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.
How to prepare
- Let us know about permits to work or site inductions
- Clear the space around the work
- Mention any locked doors, roof access or ceiling voids
Getting a quote
Quotes are quick. Call or email with a few details and you will usually have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.

Extract fan repair in Wealdstone: local notes
There are about 243 cafés, restaurants and staff canteens and about 91 takeaways across Wealdstone and its immediate surroundings (about a mile and a half), according to the Food Standards Agency’s register. Those that cook under a canopy rely on a fan that runs every hour they’re open. Lifting a replacement fan onto a London roof can need a loading slot and the building’s agreement. It’s Harrow council that sends environmental health officers to food businesses in Wealdstone. Food hygiene rules expect food premises to have suitable and sufficient ventilation. So a failed fan is worth fixing before the next service, not the next month.
If you run a school kitchen, at a school such as Marlborough Primary School or nearby, a fan that is getting noisy is best repaired in the holidays before it fails in term. Hall kitchens near Holy Trinity Church, or anywhere around Wealdstone, often use their fans only now and then, and an idle fan can stick.

Wealdstone questions
Do you work at weekends in Wealdstone?
Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in Wealdstone needn’t be disturbed. When you phone us on 0345 646 2711 or send us an email, mention when the site is quiet.
Can parking be tricky for a job in Wealdstone?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Much of our London work is done overnight, which helps.
Can we book visits on a schedule?
Yes. We run scheduled maintenance contracts, set at the interval the system needs. Each report recommends when the next visit should be.
Is TR19 cleaning required by law?
No. The law sets the duty, and TR19® is the recognised benchmark for meeting it. Under the Fire Safety Order 2005, the responsible person must reduce fire risk, and without records, many insurers may refuse or reduce a claim.
What will a fan repair or replacement cost?
We price each job after finding the cause. Repair, parts or a full replacement all cost differently, so phone us on 0345 646 2711 or use the quote form and we’ll arrange a diagnosis.
What is TR19?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not law, but it’s the benchmark.
How do you protect the area?
With sheeting and covers, before anything else happens. We keep the work contained and clean down when we finish.
Why is our extract fan so noisy?
There are several possible causes, from a worn bearing to a loose fixing. It’s worth having it diagnosed before it leads to a breakdown.
How the job changes from site to site
Belt-driven fans
With belts and pulleys, there’s more to wear. That means more to check, but often a simpler repair.
Impellers and housings
Grease settles inside the fan housing as well as on the blades. We check both and cleaning may be part of the fix.
Multi-site and managed buildings
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side, and the report can go to both.
