What extract fan repair looks like in Clapham Junction
Look up Clapham Junction on the FSA’s food hygiene register and you’ll find about 660 restaurants, cafés and works canteens and about 142 sandwich bars and takeaways across Clapham Junction and its immediate surroundings (about a mile and a half). Wherever they cook under a canopy, a failed extract fan stops the kitchen. In London, a fan on a roof or in a basement can take planning to reach, with parking and loading to arrange. Kitchens in Clapham Junction get their food hygiene inspections from Wandsworth council. Under food hygiene rules, a kitchen needs suitable and sufficient ventilation. A kitchen without a working fan has a problem to fix quickly.
Hall kitchens near Clapham Welsh Presbyterian Church, or anywhere around Clapham Junction, often use their fans only now and then, and an idle fan can stick. Holidays are the time to replace a tired kitchen fan at schools such as Christ Church CofE Primary School, rather than mid-term. If you run a kitchen close to Clapham Junction station and the extract fan is getting noisy, a planned repair after closing beats a breakdown at the rush.

Extract fan repair in Clapham Junction
Diagnosis comes before parts. We look at the motor, the belts or direct drive, the impeller and the mountings, along with the fan’s controls. After that, you get a fixed price for what’s needed. The work covers fan motors, bearings and kitchen extract fans, and common reasons people get in touch are a worn or slipping fan belt and a failed fan that needs a replacement.
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 is noisy or vibrating is giving a warning.
It’s worth checking any contractor’s accreditations. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Why act early in Clapham Junction
Fan noise tends to get worse, not better. Worn bearings can seize without much warning and the fan may stop when you’re busiest. A repair booked now is simpler than an emergency later. A busy site in Clapham Junction builds up dirt and wear quickly, so putting it off makes the eventual job larger.
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.

Honest limits
We’d rather tell you now than book work that won’t help, so these are the things it will not cover:
- A greasy canopy and duct that a fan repair will not touch
- Gas interlock faults that a Gas Safe registered engineer must deal with
- An extract system that was undersized from the start
Not sure which it is? You can phone us on 0345 646 2711 or drop us a line and we will tell you honestly before you book.

How it works
There’s very little for your team to do on the day. A contact on site lets us in at the agreed time and points us to the system, and we take it from there. Afterwards, the area is left tidy and the written report follows. In Clapham Junction, as across London, we typically work overnight or at weekends and hand the site back ready to open.
- We agree a time to attend, out of hours if needed.
- The extract is switched off and the fan opened up.
- Bearings, drive, impeller, motor and mounts are inspected.
- You hear whether repair or replacement makes sense, with a fixed quote.
- We complete the work and check the fan runs smoothly.
How to prepare
- Clear the space around the work
- Let us know how we reach the system, including roofs, risers and plant rooms
- Make sure equipment near the work can be switched off and left to cool

What affects the quote in Clapham Junction
A fixed price needs a few facts first. We look at:
- The number of sites or systems
- What state the system is in
- Parking and loading at the site
- The times the site is available
You will not find a price list here, because each job is priced on what it involves. For a fixed quote, phone us on 0345 646 2711 or send us an email, and we’ll talk you through it.
Helping us quote
You do not need the technical terms. It helps if you can send:
- Your last certificate, test record or report
- Problems your staff have spotted
- Close-ups of filters, grilles, hatches or access panels
- The roof, plant room or outside wall the system runs to
There’s no standard price list, because every site is different. We look at your system first, from pictures or on a visit, and then send you a fixed quote. To get going, ring 0345 646 2711 or send us an email.
Your questions about extract fan repair in Clapham Junction
What do you need to know about parking in Clapham Junction?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Night visits tend to make loading easier on London streets.
Do you cover Clapham Junction for emergency fan repairs?
Our emergency line runs 24/7, and Clapham Junction is within the area we cover. The number to ring is 0345 646 2711. A photo of the fan’s rating plate helps.
Do you offer maintenance contracts?
Yes. Tell us what you have and how it’s used and we’ll propose a schedule with a fixed quote.
Which kinds of sites do you work on?
Any site with a kitchen or a ventilation system to look after, from a small pub to a hospital. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
Is repair an option before replacing the whole fan?
Repair is always our starting point. Where the motor has burnt out or the fan is worn out, replacing it can be the better answer, and we’ll explain why.
Is there a survey before the work?
Yes, every time. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it, and the quote is based on that.
Can one contract cover all our sites?
Yes. Send the list of sites and the work at each and you will get one fixed quote.
What happens to the waste?
We contain it and take it with us. Grease, debris and waste water are collected as the work goes on, so it does not spread.
For landlords and multi-site operators
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 send the paperwork to whoever needs it.
From a single site to a large estate, you get the same standard: a survey first, a fixed quote, the work timed around the site and a report with photos.
What staff can safely do
Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
What the work involves, part by part
Motors and bearings
Rumbling and grinding normally come from the 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.
