Extract fan repair for kitchens and businesses in Harrow on the Hill
Not every failed fan needs replacing. Sometimes cleaning the impeller or renewing worn parts is enough and we will say so. When a fan is worn beyond sensible repair, we fit a replacement matched to the duct and the kitchen. Typical jobs include a failed fan that needs a replacement and vibration spreading from the fan into the ducts, across fan housings, belts and pulleys and bearings.
In London, a kitchen without working extraction can’t keep cooking safely, and a closed kitchen loses a night’s trade. Fans in Harrow on the Hill are often on a roof or in a basement at the end of a long duct run, so we ask about access first.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

Do you need extract fan repair in Harrow on the Hill?
Any kitchen that cooks for long hours works its fan hard, in Harrow on the Hill or anywhere else. On belt-driven fans, belts stretch, crack and start to slip and a slipping belt means slower fan speed and weaker extraction.
The symptoms we are asked about most are:
- A fan rattling in its housing
- An old fan that needs replacing
- Poor airflow at the canopy
- A dead fan motor
School kitchens cannot easily serve lunch without extraction, so if you look after one at a school like St George’s Primary Catholic Voluntary Academy, fix a failing fan before term starts.

When a fan fails in Harrow on the Hill
Food Standards Agency records list about 256 restaurants, cafés and canteens and about 112 sandwich bars and takeaways in and around Harrow on the Hill, up to about a mile and a half out. Wherever they cook under a canopy, a failed extract fan stops the kitchen. Lifting a replacement fan onto a London roof can need a loading slot and the building’s agreement. Food hygiene inspections in Harrow on the Hill are the job of Brent council’s environmental health team. A kitchen with no working extract can fall short of the suitable and sufficient ventilation food hygiene rules expect. So a failed fan is worth fixing before the next service, not the next month.
If you look after a church or hall kitchen near Christ Church, or anywhere in Harrow on the Hill, test the extract fan before a big event rather than on the day. For kitchens close to Sudbury Hill Harrow station, a fan that stops mid-service needs fixing fast, and our emergency line runs 24/7.

Common questions in Harrow on the Hill
Is parking a problem for work in Harrow on the Hill?
A loading bay, a visitor permit or off-street space near the site in Harrow on the Hill makes the visit easier to plan. Much of our London work is done overnight, which helps.
Can you come to Harrow on the Hill after we close?
Yes. We work evenings, overnight and at weekends. It means the site in Harrow on the Hill keeps running as normal. Your opening times are the first thing we ask for.

Can you set up regular visits?
Yes. Scheduled maintenance plans are part of what we do, with visits at the interval your system needs. The report from each visit recommends the next date.
What do you do with what you remove?
It’s contained and taken away. Grease, debris and waste water are collected as the work goes on, so it does not spread.
Can you look after several sites?
Yes. Our area covers London and the South East, so we can schedule a run of sites as one programme. Each site gets its own report and pictures.
Do you look at the system first?
Yes. Every job is surveyed first, from your photos and details, or with a visit where needed. A fixed quote follows.
What happens on the day
There are three stages on the day: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with photos. Most of the time goes on the work itself, which takes part of a day for most faults, with a return visit if parts have to be ordered. Security desks and permits-to-work are routine in London, so let us know what your building in Harrow on the Hill needs from us.
- You describe the fault and we arrange a visit.
- On site, the fan is safely isolated.
- The fan and its controls are checked to pin down the fault.
- You get a fixed price for putting it right.
- The work is done and the fan is tested running.
Before we arrive
- Make sure equipment near the work can be switched off and left to cool
- Mention any parking or loading restrictions
- Find the previous report, if there is one

What your team can do, and what needs us
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.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Looking after it afterwards
To keep the system working properly between visits:
- Keep the area around the fan controls clear
- Report new noises from the fan early
- Don’t turn the fan down to hide a noise
- Clean or change filters on schedule
We run the fan and check it’s steady before we go. We explain the fault and the fix along with anything else that needs watching.
The fan is part of every full TR19 clean. A clean impeller stays in balance, so planned cleaning helps the fan last.
How the job changes from site to site
Motors and bearings
A grinding or rumbling noise often means worn bearings. We diagnose whether it’s the bearings or the motor itself and then recommend the fix.
Belt-driven fans
Belt drives have more moving parts than direct-drive fans. More parts to inspect, but many faults are straightforward to fix.
Leave it or put it right?
Vibration does damage beyond the fan. It loosens fixings, strains duct connections and wears the housing and the eventual repair is larger. Planning ahead in Harrow on the Hill lets you pick a quiet night rather than lose a busy one.
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we’ll go through it with you.
