How we handle extract fan repair in Blackwall
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. The work covers bearings, fan motors and kitchen extract fans, and common reasons people get in touch are a dead fan motor and a fan worn beyond sensible repair.
For a London kitchen, a failed extract fan typically means the cooking stops. In Blackwall, as across London, fans often sit on a roof or deep in a plant space, so we ask about access first.
The sign-off is always in writing: a dated report with photos of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

Signs you need extract fan repair in Blackwall
When filters clog and ducts fill with grease, the fan has to strain. An overworked motor overheats and may cut out or fail.
What we’re most often called out for:
- A fan that keeps cutting out
- Vibration spreading from the fan into the ducts
- A fan that won’t start at all
- An extract fan that rattles or knocks
For kitchens close to Canary Wharf station, a fan that stops mid-service needs fixing fast, and our emergency line runs 24/7.

In-house cleaning or a specialist?
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.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
When it’s something else
Not every problem is solved by extract fan repair, and we’d rather say so up front. It will not put right:
- Wiring and supply faults beyond the fan itself
- Cooking smells reaching neighbours, which may need odour control
- Grease throughout the ductwork, which needs a full TR19 clean
Not sure which it is? You can call 0345 646 2711, or send details by email and we’ll tell you honestly before booking.
What the work covers
- Roof and wall fans
- Fan motors
- Belts and pulleys
- Bearings
- Kitchen extract fans
- Fan housings
Different parts, different methods
Direct-drive fans
Direct-drive fans are compact and common in kitchen extracts. When the motor fails, replacing the whole fan unit can make more sense than repairing it, and we’ll explain why.
Impellers and housings
The impeller is the bladed wheel that moves the air. Grease deposits unbalance it and make it shake.
How the visit works
There are three stages on the day: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with photos. The middle part takes longest, which takes an hour or two to diagnose, then longer if parts or a new fan are needed. Security desks and permits-to-work are routine in London, so let us know what your building in Blackwall needs from us.
- We start with the symptoms, such as rattling, humming, slow running or a fan that will not start.
- Power to the fan is isolated before we open the housing.
- We check the motor, bearings, drive, impeller and mountings.
- You get our diagnosis and a fixed quote to repair or replace.
- Once the work is done, we run the fan and check it’s steady and quiet.
How to prepare
- Make sure someone can let us in and lock up afterwards
- Clear loose items from the work area
- Agree a time when the area can be out of use

What else we do in Blackwall
Common questions in Blackwall
Who do I call if an extract fan fails in Blackwall?
Day or night, a failed fan in Blackwall can be reported on our emergency line. Call 0345 646 2711 and tell us what the fan is doing, or not doing. Let us know whether the fan is silent, noisy or tripping the power.
Do you work at weekends in Blackwall?
Yes, evening, overnight and weekend work is normal for us. It means the site in Blackwall keeps running as normal. Let us know the hours you’re closed and we’ll book within them.
Is it worth cleaning the extract while you are fixing the fan?
A repair deals with the fan, not the grease in the rest of the system. If there’s grease on the fan, a full TR19® clean is worth booking and we can plan the two together.
What about areas you cannot get to?
Anything we cannot reach goes on the report, with pictures where possible, and we explain what access is needed, for example new access panels.
Can you set up regular visits?
Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. Each report recommends when the next visit should be.
Do you provide a certificate or report?
Yes, always. It’s a dated, written report with pictures, plus a certificate via the BESCA Vent Hygiene Elite portal for TR19® Grease cleans. File it with your fire safety records.
What should go in our maintenance log?
Each report and certificate we give you, kept together in your maintenance log, along with your own cleaning log. BESA says certificates should show the date, location and technician.
How much time does a fan repair need?
As a guide, it takes anything from an hour or two to a full visit, depending on the fault. If parts have to be ordered, we will tell you how long that is likely to be.
Keeping the system healthy
Results last longer with the right care. Here’s what we suggest:
- Make sure every filter is in place and clean
- Get a noisy fan checked rather than slowed down
- Note when the fan trips or cuts out
- Report new noises from the fan early
Once we are done, the extract is back in service. We leave the area tidy and talk you through what we found.
A scheduled maintenance plan keeps the whole system on a regular cycle, which means the fan is seen regularly and problems are spotted sooner.
What extract fan repair looks like in Blackwall
There are about 517 restaurants, cafés and canteens and about 188 takeaways and sandwich shops within 1.5 miles or so of the middle of Blackwall, according to the Food Standards Agency’s register. A kitchen with a dead extract fan gets hot and smoky fast, and kitchens like these feel it at once. Environmental health officers from Tower Hamlets council inspect food businesses in Blackwall. Food premises are expected to have suitable and sufficient ventilation under food hygiene rules. Getting the fan running again is the priority. London extract fans are often at the end of long duct runs, on roofs or in basements.
School kitchens cannot easily serve lunch without extraction, so if you look after one at a school like Woolmore Primary School, fix a failing fan before term starts. If you run a church or community hall kitchen, near All Saints Church or elsewhere in Blackwall, an extract fan that rarely runs can seize or fail when it’s needed.
Blackwall is about 1 mile south-west of Canning Town, in Greater London. We carry out extract fan repair for businesses, landlords and public buildings in Blackwall and the rest of Greater London. Blackwall is one of 764 places in Greater London we cover for commercial clients.

You will find Blackwall on the A102 and A1206, which makes it straightforward for our technicians to reach for out-of-hours visits.

Why act early in Blackwall
In Blackwall, as elsewhere, an extract fan may well sit outside on a wall or roof, so its noise doesn’t stay in the kitchen. Dealing with the fault brings the noise back down before it becomes a nuisance. Shared walls, risers and roofs mean a problem at one London site seldom stays put.
When the work has to happen, how we reach it and how big the site is can all change the price. Each of those is built into the quote, and the price is fixed before work begins.
