Extract fan repair in Coulsdon, done properly
Extract fan repair starts with a diagnosis. Noise can come from grease on the impeller, worn bearings or a slipping belt, while a fan that will not start may have a motor or control fault. You hear what we’ve found before any work goes ahead. If you have a fan running too slowly to clear the kitchen and a fan worn beyond sensible repair, we can help, from roof and wall fans, belts and pulleys and bearings onwards.
London extract fans often sit on rooftops, exposed to the weather as well as the grease, and in time, bearings, belts and motors fail. A fan that’s noisy or vibrating is giving a warning.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

Landlords, agents and facilities managers
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.
From a single site to a large estate, the standard is the same: a survey first, a fixed quote, the work timed around the site and a report with photos.

Extract fans in Coulsdon
Food Standards Agency data counts about 45 restaurants, cafés and works canteens and about 29 takeaways within roughly a mile and a half of the centre of Coulsdon. Those that cook under a canopy rely on a fan that runs every hour they’re open. Food hygiene inspections in Coulsdon are the job of Croydon council’s environmental health team. Ventilation is part of food hygiene law, which expects it to be suitable and sufficient. That’s one more reason not to keep cooking with a broken fan. A failed fan in a London kitchen normally means a closed kitchen, so access details help us plan the repair.
Occasional-use kitchens, such as a hall kitchen near St Andrew's Church or elsewhere in Coulsdon, are where a stiff or seized fan can turn up. If you run a kitchen close to Coulsdon South station and the extract fan is getting noisy, a planned repair after closing beats a breakdown at the rush. For school kitchens, at schools like Smitham Primary School for example, a planned fan repair in the holidays avoids losing lunches in term time.
Coulsdon is about 13 miles south of London, in Greater London.

What affects the quote in Coulsdon
The price is fixed before any work begins. It takes into account:
- The condition of the system
- Where the site is and how we reach it
- A single visit or a regular plan
- Whether several sites go on one quote
Working hours, access and the scale of the site can all change the price. Each of those is built into the quote and give you a fixed price before we start.
What we need to know
When you call or email, it’s useful to have:
- Photos showing the whole system and its surroundings
- Close-ups of filters, grilles, hatches or access panels
- Any symptoms, from odd noises to smells or leaks
- Your last certificate, test record or report
Here’s what helps us quote: the address, the type of site and when it’s open, pictures of the system and the last certificate or report, if there is one. Then give us a ring on 0345 646 2711 or use the quote form.
What your team can do, and what needs us
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
When it’s something else
We’ll always give you a straight diagnosis, so here’s what extract fan repair will not do:
- A system that needs redesigning rather than repairing
- Grease throughout the ductwork, which needs a full TR19 clean
- Odour complaints that need filtration rather than a fan repair
If you’re not sure, just phone us on 0345 646 2711, or send details by email and we’ll give you a straight answer.

Every quote begins with a look at the system, either from pictures and details you send or from a site visit. Then we send a fixed price, before we start.
Advice
Why deal with it now?
Some kitchens run a noisy fan on a lower speed to cut the noise. It hides the symptom and weakens the extract, and the fault carries on developing. Diagnosing the fault properly is the lasting answer. It’s better booked as a planned job in Coulsdon than handled as an emergency.
Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered and we’ll price it together.
Why book with us
- Evenings, overnight and weekends, plus 24/7 emergency callout

- Fixed quotes, usually within one working day

How the job changes from site to site
Impellers and housings
Grease settles inside the fan housing as well as on the blades. We check both and cleaning may be part of the fix.
Roof and wall-mounted fans
Fans outside are exposed to rain and condensation. Rust on fixings and housings is a frequent find.
FAQs for Coulsdon
Which environmental health team covers Coulsdon?
The local authority for Coulsdon is Croydon council, and its environmental health team does the inspecting. Inspections are risk-based, so a visit can come at any time, including the week a fan stops.
Do you work overnight in Coulsdon?
Yes. We work evenings, overnight and at weekends. The work in Coulsdon can fit around your hours. Tell us your opening hours when you ask for a quote.
Is TR19 a legal requirement?
No. The law sets the duty; TR19® is the benchmark used to show it’s met. Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person has to manage fire risk, and without records, many insurers may refuse or reduce a claim.
What accreditations do you have?
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 carry full insurance.
Do you offer emergency callouts?
Yes, day and night, every day of the year. Office hours are Monday to Friday, 8am to 6pm, and the emergency line covers the rest.
Why is our extract fan so noisy?
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.
Does a fan repair include cleaning the ductwork?
A fan repair on its own does not include the ductwork. We’ll point out grease where we find it and quote for a TR19 clean if it’s needed.
Can you repair a fan rather than replace it?
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 tell you the reasons.
