Extract fan repair for kitchens and businesses in Duckett's Green
We treat a failing fan much like a patient: listen to it, diagnose the fault, then treat it. What you want back is a fan that runs smoothly and a plain account of what we found. If you have vibration spreading from the fan into the ducts and a motor that trips out or overheats, we can help.
London extract fans often sit on rooftops, exposed to the weather as well as the grease, and bearings, belts and motors wear out in the end. A fan that’s noisy or vibrating is giving a warning.
Accreditations are easy to claim and worth checking. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

For landlords and multi-site operators
Running several sites is easier with one contractor. We cover South East England and London, so visits at different addresses can be planned together and kept to a regular schedule.
Records are where multi-site compliance often slips. Each visit ends with a dated report and photos, ready to show insurers, fire officers or EHOs.
Extract fan repair in Duckett's Green: local notes
Look up Duckett's Green on the FSA’s food hygiene register and you will find about 471 restaurants, cafés and canteens and about 166 takeaways within 1.5 miles or so of the middle of Duckett's Green. For any of them with a canopy, the extract fan is what keeps the kitchen usable. It’s Haringey council that sends environmental health officers to food businesses in Duckett's Green. Food hygiene rules expect food premises to have suitable and sufficient ventilation. So a failed fan is worth fixing before the next service, not the next month. In London, a fan on a roof or in a basement can take planning to reach, with parking and loading to arrange.
If you cook near Hornsey station, long trading hours wear fan belts and bearings, so noise and vibration are worth reporting early. For school kitchens, at schools like St John Vianney RC Primary School for example, a planned fan repair in the holidays avoids losing lunches in term time.

In-house cleaning or a specialist?
Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.
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.

What else we do in Duckett's Green

Advice
What happens if it’s left?
A struggling motor runs hotter and works harder. That shortens its life, and when it finally fails, it may take other parts with it. Catching it early keeps the repair small. In a London building, a problem in a duct, damper or fan rarely stays in one unit.
No two sites are the same, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all play a part.
Why us?
- Accredited under CHAS and SafeContractor, with ISO 9001
- One number for every site across the South East and London
- Fixed quotes from a survey or photos
- BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease

Different parts, different methods
Fan controls
We check the controls as part of every diagnosis, because a fan that won’t start is not always a failed motor.
Belt-driven fans
Belt-driven fans have a motor that turns the impeller through belts and pulleys. Worn belts squeal and slow the fan down, so we check the pulleys and bearings as well.
Signs you need extract fan repair in Duckett's Green
When filters clog and ducts fill with grease, the fan has to strain. A motor that strains runs hot and may cut out or fail.
Look out for any of the following:
- A belt-driven fan that squeals
- A fan rattling in its housing
- A failed fan that needs a replacement
- An overheating extract motor
If you look after a church or hall kitchen near Christ Church, or anywhere in Duckett's Green, test the extract fan before a big event rather than on the day.

Duckett's Green questions
Can the work in Duckett's Green 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. Just phone us on 0345 646 2711, or email photos with your opening times and we’ll plan around them.
What do you need to know about parking in Duckett's Green?
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.
What happens to the waste?
It leaves the site with us when we go. During the work, it’s contained to keep the area clean.
Can you supply and fit a replacement fan?
We can. Replacing a fan is part of our fits and repairs work, and we will explain the options.
Which accreditations do you hold?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.
Which records should we keep?
Each report and certificate we give you, filed in the maintenance log with your in-house cleaning records. BESA advises that certificates record the date, location and technician.
What is TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.
Do you survey before quoting?
Yes. Every job is surveyed first, from your pictures and details, or with a visit where needed. A fixed quote follows.
Fixed quotes for extract fan repair in Duckett's Green
Some jobs are bigger than they look, and some smaller. The main factors:
- The scale of the work
- Parking and loading at the site
- The times the site is available
- Site rules, permits and inductions
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you are not sure what’s needed, phone us on 0345 646 2711 or use the quote form for straight advice and a fixed quote.
Asking for a quote
What to send for a quote:
- A few general shots of the system
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Where the site is and what kind of site it is
- Your last certificate, test record or report
Quoting starts with a diagnosis, either from photos and details you send or from a site visit. Then we send a fixed price, before we start.
