Extract fan repair across Crooked Billet

What the work involves, part by part

Direct-drive fans

Direct-drive fans are compact and common in kitchen extracts. If the motor has gone, a replacement unit is often the sensible option and we’ll talk you through it.

Roof and wall-mounted fans

An external fan’s rattle can be heard outside. It’s often down to loose mounts or worn bearings.

Extract fan repair for kitchens and businesses in Crooked Billet

The extract fan is what pulls smoke, heat and steam out of the kitchen. Once it turns noisy, sluggish or stops altogether, the cooking area soon fills with heat and fumes. Our engineers track down the fault and fix it with a repair or a replacement. Typical jobs include a fan running too slowly to clear the kitchen and an overheating extract motor, across fan motors, roof and wall fans and fan housings.

Replacing a fan in a London building often means working at height or in a tight plant space, with parking and lifting to arrange in Crooked Billet. Repairs can be done out of hours so the kitchen keeps trading.

Good records are part of the job. You get a written report with pictures after every visit, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

Staff cleaning versus specialist work

Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.

Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.

Aftercare tips

Simple habits between visits make a real difference. We recommend:

  • Tell us about a new rattle or whine straight away
  • Avoid lowering the speed to quieten a fault
  • Make sure staff know who to call if the fan fails
  • Keep the area around the fan controls clear

Once the fan is running smoothly, keep the filters clean. Less grease on the impeller means less wear and the quieter it runs.

When filters block, the fan works harder. Changing or cleaning them on time takes load off the motor and helps prevent overheating.

Multi-site and managed buildings

From a single site to a large estate, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with photos.

Facilities teams in offices, schools and healthcare sites book us too across Greater London. Larger estates can be phased building by building to keep disruption down.

How the visit works

Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. All we need from you is clear access and the right equipment switched off. On site, the work takes a few hours for most repairs, longer for a full fan replacement. In a London area like Crooked Billet, parking, loading and building access are planned before the day of the work.

  1. We ask what the fan is doing, from noise and vibration to a full stop.
  2. With the fan safely isolated, we open it up for a proper look.
  3. We check the motor, bearings, drive, impeller and mountings.
  4. You hear what’s wrong and what it will cost, with a fixed quote, before we go ahead.
  5. Once the work is done, we run the fan and check it’s steady and quiet.

How to prepare

  • Clear the space around the work
  • Allow time for equipment near the work to be turned off and cool down
  • Tell us about site rules, permits or sign-in

Getting a quote

Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, you get a fixed price before we start.

Advice

Crooked Billet: your questions answered

What do you need to know about parking in Crooked Billet?

A loading bay, a visitor permit or off-street space near the site in Crooked Billet makes the visit easier to plan. If the building has a loading slot system, we’ll book into it.

What if my kitchen extract fan stops in Crooked Billet at night?

We run a 24/7 emergency line for failed extract fans, and Crooked Billet is part of our area. Ring 0345 646 2711 at any hour and describe the fault. Let us know whether the fan is silent, noisy or tripping the power.

What types of premises do you cover?

We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, plus food production and leisure sites.

What will a fan repair or replacement cost?

We cannot price it without knowing the fault. Once we have looked at it, you get a fixed quote for whichever option you choose.

Does the report say when we need you again?

Yes. How often depends on use and condition and the report sets out why.

Is it worth cleaning the extract while you are fixing the fan?

Doing both together is often sensible. A TR19 clean covers the canopy, plenum, ductwork and fan, with a certificate and photo report.

Does a faulty extract fan always need replacing?

It depends on the fault. We diagnose first and tell you whether a repair is realistic, then give you a fixed quote.

Who is responsible for fire safety on the premises?

Under the Regulatory Reform (Fire Safety) Order 2005, it’s the responsible person: normally the employer or whoever controls the premises. Landlords, facilities managers and managing agents can also hold responsibility.

When to call us in Crooked Billet

Kitchen extract fans in Crooked Billet face the same conditions as anywhere else: hot, greasy, damp air for hours on end. Condensation can corrode parts, and age catches up with every fan in the end.

Signs it’s time to call us include:

  • Weak extraction and a smoky kitchen
  • A fan that keeps cutting out
  • An extract fan that has stopped working
  • A whining or grinding extract motor

Occasional-use kitchens, such as a hall kitchen near Christ Church or elsewhere in Crooked Billet, are where a stiff or seized fan can turn up.

Questions to ask before you book

Why it’s worth doing now in Crooked Billet

In Crooked Billet, as elsewhere, an extract fan may well sit outside on a 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. Choosing the date yourself beats having a fault choose it for you.

What you pay depends on how big the system is, what state it’s in and access to every part of it. We give you a fixed price before any work starts, so there are no surprises.

Extract fan repair in Crooked Billet: local notes

Look up Crooked Billet on the FSA’s food hygiene register and you will find about 208 restaurants, cafés and canteens and about 32 takeaways and sandwich shops in Crooked Billet and the streets around it, up to about 1.5 miles out. For any of them with a canopy, the extract fan is what keeps the kitchen usable. It’s Merton council that sends environmental health officers to food businesses in Crooked Billet. Ventilation is part of food hygiene law, which expects it to be suitable and sufficient. So a failed fan is worth fixing before the next service, not the next month. Lifting a replacement fan onto a London roof can need a loading slot and the building’s agreement.

If you run a kitchen close to Raynes Park station and the extract fan is getting noisy, a planned repair after closing beats a breakdown at the rush. Holidays are the time to replace a tired kitchen fan at schools such as Wimbledon College, rather than mid-term.
