Greater London · Extract fan repair and replacement
Telegraph Hill extract fan repair
Professional extract fan repair in and around Telegraph Hill, booked around your opening hours and finished with a written report and photos.

- Vibration spreading from the fan into the ducts
- A fan running too slowly to clear the kitchen
Extract fan repair in Telegraph Hill, done properly
We treat a failing fan much like a patient: listen to it, diagnose the fault, then treat it. The aim is steady, quiet extraction and a plain account of what we found. The work covers bearings, roof and wall fans and fan motors, and common reasons people get in touch are an extract fan that has stopped working and an overheating extract motor.
Replacing a fan in a London building often means working at height or in a tight plant space, and in Telegraph Hill, parking and lifting are part of that. Repairs can be done out of hours so the kitchen keeps trading.
Duct Doctor has been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

Different parts, different methods
Direct-drive fans
In a direct-drive fan, the impeller sits on the motor shaft. With no belts to wear, we look at the motor, bearings and impeller.
Roof and wall-mounted fans
Many kitchen extract fans sit on a roof or an outside wall. Access affects how long a repair takes, so we ask about it early.
What we’re called out for in Telegraph Hill
Fans everywhere, Telegraph Hill included, live in a hard environment: hot, greasy, damp air for hours on end. Condensation can corrode parts and eventually any fan simply wears out.
Any of these means the system needs a check-up:
- A fan worn beyond sensible repair
- A belt-driven fan that squeals
- An extract fan that rattles or knocks
- An extract fan that has stopped working
Holidays are the time to replace a tired kitchen fan at schools such as Haberdashers' Hatcham College, rather than mid-term.
What your quote should include
- Whether a survey comes first
- How VAT is shown on the quote
- Whether a written report and photos are included
- Whether inaccessible sections are listed on the report
What a clean will not put right
It’s worth knowing the limits before booking:
- Grease throughout the ductwork, which needs a full TR19 clean
- Smells from the discharge that need odour control equipment
- Faults on the gas side of an interlock system, which need a Gas Safe registered engineer
If in doubt, give us a ring on 0345 646 2711 or email us and we will say what we think.
What the work covers
- Roof and wall fans

Managing agents and facilities teams in Telegraph Hill
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We’re happy to deal with either side, and the report can go to both.
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Each site gets its own report and pictures, so each one has its own record.
What we do, step by step
Everything the job needs comes with us, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. The visit takes a few hours on site, depending on the fault and the access to the fan. For a job in Telegraph Hill, tell us about loading bays, permits, lifts and roof access when you book.
- You describe the fault and we arrange a visit.
- On site, the fan is safely isolated.
- We diagnose the fault, checking the controls as well as the fan.
- A fixed quote for the repair or replacement follows.
- We fix the fault and run the fan to check it.
Preparing for the visit
- Mention any sign-in, permit or induction we need
- Let us know about parking and loading
- Find the previous report, if there is one
Get a fixed quote
Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before we start.

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.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
Fixed quotes for extract fan repair in Telegraph Hill
The price is fixed before any work begins. It takes into account:
- The times the site is available
- Whether we need access equipment or extra panels
- Travel, parking and unloading
- Whether it’s a one-off visit or part of a schedule
One small site or a whole estate, the quote is built the same way: what needs doing, how we get to it and when. You will have a fixed price before work begins.
What to send for a quote
To help us quote quickly, send us:
- Detail shots of panels, filters and grilles
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- How we’d reach plant on a roof or in a plant room
- The times we could work without disrupting the site
To get a fixed quote, call 0345 646 2711 or drop us a line and tell us the type of site, your opening hours and roughly what the system looks like. A few pictures and your last certificate or report help a lot. We usually come back within one working day.
When a fan fails in Telegraph Hill
There are about 443 restaurants, cafés and works canteens and about 329 takeaways within roughly a mile and a half of the centre of Telegraph Hill, 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. Kitchens in Telegraph Hill get their food hygiene inspections from Lewisham council. Ventilation is part of food hygiene law, which expects it to be suitable and sufficient. A kitchen without a working fan has a problem to fix quickly. London extract fans are often at the end of long duct runs, on roofs or in basements.
Occasional-use kitchens, such as a hall kitchen near St Catherine's Hatcham or elsewhere in Telegraph Hill, are where a stiff or seized fan can turn up. If you run a kitchen close to Brockley station and the extract fan is getting noisy, a planned repair after closing beats a breakdown at the rush.

Common questions in Telegraph Hill
Is parking a problem for work in Telegraph Hill?
A loading bay, a visitor permit or off-street space near the site in Telegraph Hill makes the visit easier to plan. Working overnight, as we often do in London, usually makes it simpler.
Can you come out to a failed extract fan in Telegraph Hill out of hours?
Telegraph Hill is covered, and our emergency callout runs 24/7. Phone 0345 646 2711 and we will talk through the fault and access. Let us know whether the fan is silent, noisy or tripping the power.
How do you keep the site clean during the work?
Floors and surfaces near the work are sheeted before we start, and waste is contained as we go. Before we leave, we tidy up and clean down.
Do you work with multi-site operators?
Yes. We work across South East England and London, so we can schedule a run of sites on one programme. Each site gets its own report and pictures.
Are you fully insured?
Yes. We carry full insurance, and we have been trading since 2009.
What does TR19 mean?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not law, but it’s the benchmark.
Does a faulty extract fan always need replacing?
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 will tell you the reasons.
How long will the fan be out of action?
It depends on the fault, but as a guide it takes a few hours for most repairs, longer for a full fan replacement. We will give you a better idea once we’ve diagnosed it.
