How we handle extract fan repair in Thornwood Common
Across Thornwood Common, we deal with fan faults of every kind, from a squeal at start-up to a fan that won’t run at all. We find the cause, give you a fixed price and fix it, or the fan is replaced if repair does not make sense. We are often asked to deal with weak extraction and a smoky kitchen and a failed fan that needs a replacement, on fan housings, kitchen extract fans and roof and wall fans.
In a small place like Thornwood Common, fans are often on an outside wall or roof, open to wind and rain. That, with the grease, is hard on motors and bearings.
The paperwork matters as much as the work. You get a written report with pictures after every visit, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. All we need from you is clear access and the right equipment switched off. On site, the work takes a few hours on site, depending on the fault and the access to the fan. Somewhere like Thornwood Common, lanes, gates and parking are worth mentioning in advance.
- We take details of the symptoms and book a time that suits the kitchen.
- 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.

Food Standards Agency data counts about 8 restaurants, cafés and canteens in Thornwood Common and the streets around it, up to about 1.5 miles out. Every one of them that cooks under a canopy depends on its extract fan to keep cooking. Thornwood Common, about 18 miles from central London, is within our usual area. We work evenings, overnight and at weekends, so the visit fits around the site. It’s Epping Forest council that sends environmental health officers to food businesses in Thornwood Common. Food premises are expected to have suitable and sufficient ventilation under food hygiene rules. That makes a fan repair urgent rather than something to put off.

Different parts, different methods
Motors and bearings
The motor and its bearings work hardest. Hot, greasy air and long days wear them down.
Belt-driven fans
Belt drives have more moving parts than direct-drive fans. More parts to inspect, but many faults are straightforward to fix.

Common problems we fix in Thornwood Common
Some faults are in the controls rather than the fan. Speed controllers, isolators and wiring can all fail, and a fan that will not start is not always a dead motor.
Signs it’s time to call us include:
- Weak extraction and a smoky kitchen
- A failed fan that needs a replacement
- A fan rattling in its housing
- A worn or slipping fan belt
For school kitchens, at schools like St John's Church of England Voluntary Controlled School for example, a planned fan repair in the holidays avoids losing lunches in term time.
What to look for in a quote

- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- Whether the figure could change on the day
What staff can safely do
Good housekeeping makes our visits easier, not unnecessary. 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.
Multi-site and managed buildings
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.
Whether it’s one building or many, you get the same standard: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
Thornwood Common: your questions answered
Is there an emergency callout for extract fans in Thornwood Common?
Day or night, a failed fan in Thornwood Common can be reported on our emergency line. Phone 0345 646 2711 and we will talk through the fault and access. Details of the make and model help us plan the repair.
Do you work at weekends in Thornwood Common?
Yes. We work evenings, overnight and at weekends. The work in Thornwood Common can fit around your hours. Tell us your opening hours when you ask for a quote.
What paperwork should we keep on file?
Visit reports, certificates and your in-house cleaning logs. Insurers, fire officers and EHOs may all ask to see them, so keep them together and easy to find.
Is it worth cleaning the extract while you’re 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 is TR19?
A BESA specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not legislation, but it’s the standard people check against.
Do you work with multi-site operators?
Yes. One number covers all your sites across London and the South East, with visits on a regular schedule.
How much notice do you need?
For planned work, earlier is better, particularly if your next visit is nearly due. Emergencies are different, because our line is open 24/7.
How do you keep the site clean during the work?
We start with protection: floor sheeting and covers over nearby surfaces and equipment. The area is left tidy, with our waste taken away.
When it’s something else
Before you book, it helps to know what’s not included:
- An extract system that was undersized from the start
- A greasy canopy and duct that a fan repair will not touch
- Cooking smells reaching neighbours, which may need odour control
Not sure which it is? You can phone us on 0345 646 2711 or send us an email and we will tell you honestly.
