Surrey · Extract fan repair and replacement
Dora's Green extract fan repair
Extract fan repair for Dora's Green, from a team that has been trading since 2009. Out-of-hours visits and 24/7 emergency callout.
- A belt-driven fan that squeals
- A fan that keeps cutting out
- A fan running too slowly to clear the kitchen
What the work involves, part by part
Roof and wall-mounted fans
An external fan’s rattle can be heard outside. Loose fixings and worn mounts are often the cause.
Impellers and housings
The impeller does the work of moving air through the system. Grease on it throws it out of balance and cause vibration.
Extract fan repair in Dora's Green
Everything a kitchen extract does depends on the fan. When it starts to rattle, hum or slow down, the kitchen gets hot and smoky very quickly. We find out why and put it right, by repairing the fan or replacing it. If you have a humming noise from the fan motor and a fan that won’t start at all, we can help, from fan housings, fan motors and belts and pulleys onwards.
In a small place like Dora's Green, fans are often on an outside wall or roof, open to wind and rain. Weather and grease together wear out motors and bearings.
Nothing is signed off by word of mouth: a dated report with pictures of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

Dora's Green: your questions answered
Can the work in Dora'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. When you call 0345 646 2711 or use the quote form, mention when the site is quiet.
Which council inspects kitchens in Dora's Green?
In Dora's Green, it’s Hart council that carries out food hygiene inspections. Inspections are risk-based, so a visit can come at any time, including the week a fan stops.
Is it worth cleaning the extract while you are fixing the fan?
The ductwork is a separate job. We’ll point out grease where we find it and quote for a TR19 clean if it’s needed.
What do you do to protect the area?
Protection goes down first: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.
Can you repair a fan rather than replace it?
Often, yes. Many faults are fixed by cleaning the impeller or renewing worn parts, and we will always say when repair makes sense.
What does TR19 mean?
TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Do you offer maintenance contracts?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, to suit the system and how it’s used.
What if parts of the system cannot be reached?
We record them on the report, with a note of where it is, and we tell you what would make it reachable, for example new access panels.
What your team can do, and what needs us
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
What happens if it’s left?
Some kitchens run a noisy fan on a lower speed to cut the noise. It hides the symptom and weakens the extract while the underlying wear continues. A proper diagnosis in Dora's Green gets to the real cause. In a small place like Dora's Green, a system that fails can take a site out of use.
Every site is different, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all play a part.

What a clean won’t put right
It’s worth knowing the limits before booking:
- Gas interlock faults that a Gas Safe registered engineer must deal with
- Wiring and supply faults beyond the fan itself
- Ductwork designed too small for the kitchen’s cooking

Extract fan repair in Dora's Green: local notes
Kitchens in Dora's Green get their food hygiene inspections from Hart council. Under food hygiene rules, a kitchen needs suitable and sufficient ventilation. That is one more reason not to keep cooking with a broken fan. At about 37 miles from central London, Dora's Green sits well inside the area we cover. The visit is fixed around your opening hours, not ours.
If you run a church or community hall kitchen, near St Mary's Church or elsewhere in Dora's Green, an extract fan that rarely runs can seize or fail when it’s needed. If you run a school kitchen, at a school such as Crondall Primary School or nearby, a fan that is getting noisy is best repaired in the holidays before it fails in term.
