Extract fan repair in Cranbrook
Extract fan repair starts with a diagnosis. A noisy fan might need cleaning, new bearings or a new belt; a dead fan can point to the motor or its controls. We explain the problem, and what it will take, before work begins. Common call-outs are for vibration spreading from the fan into the ducts and a dead fan motor, on roof and wall fans, fan motors and belts and pulleys.
Rooftop fans in London take the weather as well as the grease from below, and in time, bearings, belts and motors fail. A fan that is noisy or vibrating is giving a warning.
Insurers, fire officers and environmental health officers all look at records. That’s why every job is written up in a report with pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

What happens if it’s left?
A noisy fan rarely fixes itself. Worn bearings can seize without much warning, and that often happens mid-service. A repair booked now is simpler than an emergency later. Shared walls, risers and roofs mean a problem at one London site seldom stays put.
Putting the work off seldom saves money. Problems in a system tend to grow, and a neglected system can mean more work. If you are not sure what’s needed, phone us on 0345 646 2711 or send us an email for straight advice and a fixed quote.

FAQs for Cranbrook
Who carries out food hygiene inspections in Cranbrook?
The local authority for Cranbrook is Redbridge council, and its environmental health team does the inspecting. Keeping the fan serviced is easier than explaining a broken one on inspection day.
Do you work at weekends in Cranbrook?
Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. Let us know the hours you are closed and we’ll book within them.
Can you supply and fit a replacement fan?
Yes. If repair isn’t sensible, we replace the fan. The replacement has to suit the ductwork and the cooking before recommending a unit.
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’re fully insured.
What’s 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 work in Cranbrook?
Yes. Our technicians work in Cranbrook, within the South East and London area we cover.
Do we lose a day’s trading?
Not normally. We need the work area to ourselves while we’re on site, so we book a time when it would be closed anyway.
Does a fan repair include cleaning the ductwork?
Doing both together is often sensible. A full clean takes in the whole extract, including the fan, with a certificate and photo report.
Staff cleaning versus specialist work
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. Leave those to us.
Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
When it’s something else
We will not sell you work that does not address the problem, so these are the things it will not cover:
- An extract system that was undersized from the start
- Faults on the gas side of an interlock system, which need a Gas Safe registered engineer
- Cooking smells reaching neighbours, which may need odour control
If in doubt, call us on 0345 646 2711 or use the quote form and we’ll say what we think.
Where we work
- Bearings
- Kitchen extract fans

When to call us in Cranbrook
In Cranbrook, as anywhere, long cooking days mean long hours for the fan. On belt-driven fans, belts stretch, crack and start to slip and a slipping belt means slower fan speed and weaker extraction.
What we are most often called out for:
- An extract fan that has stopped working
- A whining or grinding extract motor
- An old fan that needs replacing
- A knocking noise from the extract fan
If you run a church or community hall kitchen, near St Clement's Church or elsewhere in Cranbrook, an extract fan that rarely runs can seize or fail when it’s needed.

How the visit works
Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and the same goes into the written report. The visit takes an hour or two to diagnose, then longer if parts or a new fan are needed. Managed blocks in London often need contractors booked in ahead, and we are happy to deal with the agent directly for a site in Cranbrook.
- We ask what the fan is doing, from noise and vibration to a full stop.
- The fan is isolated and opened up so we can see inside.
- 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.
Getting ready for the visit
- Allow time for equipment near the work to be turned off and cool down
- Tell us where we can park and unload
- Mention any locked doors, roof access or ceiling voids
Get a fixed 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. Then we send a fixed price, before work begins.
Advice
Between visits
Aftercare is simple, and it helps at the next visit:
- Keep all filters fitted while cooking
- Do not wait for a noisy fan to stop
- Keep access to the fan controls unobstructed
- Get a noisy fan checked rather than slowed down
We run the fan and check it’s steady before we go. You will hear what we found and what we did along with anything else that needs watching.
Small faults, like a worn belt, are quick to fix. Left for months, they can damage the motor or bearings so early attention pays.
Multi-site and managed buildings
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.
Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept on a regular cycle.
