Part by part
Fan controls
Supply faults are a job for an electrician. We’ll tell you if that is what we find and explain what we found.
Belt-driven fans
Squealing at start-up often points to a belt. We check the belt condition, tension and alignment and replaced if they’re worn.
Extract fan repair in New Denham
Across New Denham, we deal with fan faults of every kind, from rattling and humming to a fan that has stopped dead. The fault is diagnosed, quoted at a fixed price and put right or fit a replacement when it’s beyond repair. The work covers fan motors, kitchen extract fans and bearings, and people most often call us about weak extraction and a smoky kitchen and a whining or grinding extract motor.
Rural kitchens often have fans mounted on outside walls or roofs, exposed to the weather. Weather and grease together wear out motors and bearings.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

Advice
What affects the cost of extract fan repair
Every site gets its own quote. This is what makes a difference:
- When the work can happen, such as evenings, overnight or weekends
- The number of sites or systems
- The scale of the work
- The condition we find in the survey
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. Call for a fixed quote and we will explain each part.
Asking for a quote
A few details help us quote accurately. When you get in touch, it helps to send:
- The paperwork from the last visit, if you have it
- Photos showing the whole system and its surroundings
- Detail shots of panels, filters and grilles
- Where the site is and what kind of site it is
Getting a quote does not take long. Send a few details and photos, and we typically reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
New Denham: your questions answered
Do you cover New Denham for emergency fan repairs?
Extract fan emergencies in New Denham are covered around the clock. Ring 0345 646 2711 at any hour and describe the fault. Let us know whether the fan is silent, noisy or tripping the power.
Can the work in New Denham be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. Your opening times are the first thing we ask for.
What happens if you cannot reach some of it?
They’re listed in the report, never skipped quietly. The report says which parts couldn’t be reached and why, and we can quote to improve the access.
Do you work with multi-site operators?
Yes. Send the list of sites and the work at each and we will quote them together.
What’s TR19?
A BESA specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not law, but it’s the benchmark.
Are you insured?
Yes. We are fully insured, and the details are available on request.
Does a faulty extract fan always need replacing?
In many cases, yes. A clean, a new belt or new bearings can bring a fan back and we only recommend replacement when repair does not make sense.
What causes a noisy extract fan?
There are several possible causes, including bearings, belts, grease and mounts. It’s worth having it diagnosed before it leads to a breakdown.
When it’s something else
A few issues sit outside what this work can do:
- A greasy canopy and duct that a fan repair will not touch
- Problems with the electrical supply to the fan (an electrician’s job)
- Ductwork designed too small for the kitchen’s cooking
Not sure which it is? You can call us on 0345 646 2711 or drop us a line and we’ll tell you honestly before booking.

Common problems we fix in New Denham
Over the years, mountings loosen and rubber mounts break down. Then every vibration is passed into the duct and the building and that is a common source of rattles.
Keep an eye out for these warning signs:
- An extract fan that rattles or knocks
- A failed fan that needs a replacement
- Poor airflow at the canopy
- A motor that trips out or overheats
Holidays are the time to replace a tired kitchen fan at schools such as Hermitage Primary School, rather than mid-term.

What your team can do, and what needs us
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That’s our job.
What extract fan repair looks like in New Denham
There are about 94 restaurants, cafés and works canteens and about 48 takeaways in New Denham and the streets around it, up to about 1.5 miles out, according to the Food Standards Agency’s register. For any of them with a canopy, the extract fan is what keeps the kitchen usable. New Denham, about 17 miles from central London, is within our usual area. We work evenings, overnight and at weekends, so the visit fits around the site. Kitchens in New Denham get their food hygiene inspections from Hillingdon council. Ventilation is part of food hygiene law, which expects it to be suitable and sufficient. That makes a fan repair urgent rather than something to put off.
Occasional-use kitchens, such as a hall kitchen near St Francis or elsewhere in New Denham, are where a stiff or seized fan can turn up.

Why it’s worth doing now in New Denham
Wherever the kitchen is, New Denham included, the fan often sits on an outside wall or roof, where a rattle or a whine can be heard beyond the kitchen. Dealing with the fault brings the noise back down before neighbours notice. A fault that closes a site in a village like New Denham affects everyone who depends on it.
One small site or a whole estate, we price it on the same basis: what needs doing, how we get to it and when. You will have a fixed price before we start.
