When to call us in Canonbury
In Canonbury, as anywhere, long cooking days mean long hours for the fan. On belt-driven fans, belts stretch, crack and start to slip, so the fan squeals or turns more slowly.
Look out for any of the following:
- A whining or grinding extract motor
- An extract fan that rattles or knocks
- A motor that trips out or overheats
- A squealing belt on start-up
For a takeaway near Canonbury station, a fan that fails on a busy evening means turning customers away, and our emergency line runs 24/7.

How we handle extract fan repair in Canonbury
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, by repairing the fan or replacing it. The work covers fan motors, roof and wall fans and fan housings, and common reasons people get in touch are a motor that trips out or overheats and an old fan that needs replacing.
Rooftop fans in London take the weather as well as the grease from below, and bearings, belts and motors wear out in the end. Noise and vibration are worth reporting before the fan stops.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

The process
A visit follows the same order every time: sheeting and protection first, make the system safe, carry out the extract fan repair, clear away and hand over the paperwork. The visit itself takes a few hours on site, depending on the fault and the access to the fan. Security desks and permits-to-work are routine in London, so let us know what your building in Canonbury needs from us.
- We agree a time to attend, out of hours if needed.
- The extract is switched off and the fan opened up.
- We inspect every moving part and the fixings.
- We explain the options and quote a fixed price.
- The fan is repaired or replaced, then checked running.
Before we arrive
- Make sure equipment near the work can be switched off and left to cool
- Mention any locked doors, roof access or ceiling voids
- Dig out any earlier paperwork for the system
Ask for a quote
Every quote begins with a look at the system, from your photos and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work, before work begins.

Multi-site and managed buildings
Facilities teams in offices, schools and healthcare sites book us too across Greater London. Work can be phased by floor, building or site around the people who use them.
If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and photos, so each one has its own record.
What extract fan repair looks like in Canonbury
Look up Canonbury on the FSA’s food hygiene register and you’ll find about 1,209 restaurants, cafés and canteens and about 277 sandwich bars and takeaways across Canonbury and its immediate surroundings (about a mile and a half). Every one of them that cooks under a canopy depends on its extract fan to keep cooking. A failed fan in a London kitchen typically means a closed kitchen, so access details help us plan the repair. Environmental health officers from Islington council inspect food businesses in Canonbury. Food hygiene rules expect food premises to have suitable and sufficient ventilation. Getting the fan running again is the priority.
If you run a school kitchen, at a school such as Rotherfield Primary School or nearby, a fan that’s getting noisy is best repaired in the holidays before it fails in term. Occasional-use kitchens, such as a hall kitchen near St Paul's Church or elsewhere in Canonbury, are where a stiff or seized fan can turn up.

Leave it or put it right?
Where the cooking gas supply is interlocked with the extract, a failed fan can stop the kitchen cooking. Without extraction, the heat and fumes build up fast, so a failing fan is worth dealing with early. Shared walls, risers and roofs mean a problem at one London site seldom stays put.
Combining work into one visit or one programme can make for a more efficient booking. Tell us about everything you’d like looked at and we will price it together.

Your questions about extract fan repair in Canonbury
Who would carry out a food hygiene inspection at a kitchen in Canonbury?
Kitchens in Canonbury are inspected by Islington council’s environmental health officers. Keeping the fan serviced is easier than explaining a broken one on inspection day.
Does London parking affect a job in Canonbury?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. Night visits tend to make loading easier on London streets.
Is it worth cleaning the extract while you are fixing the fan?
A fan repair on its own does not include the ductwork. We’ll tell you what we see and quote for a TR19 clean if it’s needed.
Is there a survey before the work?
Yes. We always survey first, from your photos and details, or with a visit where needed. Then you get a fixed quote.
Do you cover Canonbury?
Yes. Our technicians work in Canonbury, as part of our area across London and the South East.
Does the extract need to be off for a fan repair?
The extract must be off while the fan is opened up. We plan the visit around your hours, so service is not lost.
What should go in our maintenance log?
Every certificate and report from each visit, kept together in your maintenance log with your in-house cleaning records. BESA says certificates should show the date, location and technician.
What causes a noisy extract fan?
Grease on the blades throws the fan out of balance and that’s one of the most common reasons. Bearings, belts and mountings can also be to blame.
When something else is needed
A few issues sit outside what this work can do:
- A greasy canopy and duct that a fan repair won’t touch
- Gas interlock faults that a Gas Safe registered engineer must deal with
- An extract system that was undersized from the start
If you’re not sure, just call us on 0345 646 2711 or email us and we’ll give you a straight answer before booking.

In-house cleaning or a specialist?
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
What affects the cost of extract fan repair
There’s no set price list, because sites vary so much. What we look at:
- The condition we find in the survey
- Any permits to work or inductions
- Whether we need access equipment or extra panels
- The number of sites or systems
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we will go through it with you.
What we need to know
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- When the site is open and when it’s quiet
- The roof, plant room or outside wall the system runs to
- Close-ups of filters, grilles, hatches or access panels
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
To get a fixed quote, phone us on 0345 646 2711, or send details by email and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. We normally come back within one working day.
