Extract fan repair in Grahame Park, done properly
Grease is hard on extract fans. A coated impeller spins unevenly and the vibration wears out bearings and fixings. That’s why we check the grease whenever we work on a fan, and a full TR19® clean can be booked alongside. Common call-outs are for a fan worn beyond sensible repair and a whining or grinding extract motor, across bearings, kitchen extract fans and roof and wall fans.
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.
The paperwork matters as much as the work. You get a written report with photos after each visit, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

Staff cleaning versus specialist work
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that is where we come in.
What happens if it’s left?
Fan noise tends to get worse, not better. Worn bearings can seize without much warning and the fan may stop when you are busiest. Sorting it while it still runs is far easier to plan. Leaving it on a busy London site only adds to the work.
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you’re unsure, give us a ring on 0345 646 2711 or use the quote form for straight advice and a fixed quote.

When a fan fails in Grahame Park
Food Standards Agency data counts about 183 restaurants, cafés and canteens and about 108 sandwich bars and takeaways within 1.5 miles or so of the middle of Grahame Park. Wherever they cook under a canopy, a failed extract fan stops the kitchen. Environmental health officers from Barnet council inspect food businesses in Grahame Park. Under food hygiene rules, a kitchen needs suitable and sufficient ventilation. That is one more reason not to keep cooking with a broken fan. A failed fan in a London kitchen typically means a closed kitchen, so access details help us plan the repair.
If you run a kitchen close to Mill Hill Broadway station and the extract fan is getting noisy, a planned repair after closing beats a breakdown at the rush. If you manage a school such as St James' Catholic High School and the kitchen fan is getting louder, the next break is the time to deal with it. If you run a church or community hall kitchen, near St Augustine Grahame Park or elsewhere in Grahame Park, an extract fan that rarely runs can seize or fail when it’s needed.

FAQs for Grahame Park
Is parking a problem for work in Grahame Park?
Tell us where a van can stop near your site in Grahame Park, and about any building rules on loading. Much of our London work is done overnight, which helps.
Which council inspects kitchens in Grahame Park?
That’s Barnet council, whose environmental health officers carry out food hygiene inspections in Grahame Park. Keeping the fan serviced is easier than explaining a broken one on inspection day.
What does TR19 mean?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It sets out inspection, cleaning and record keeping, and it takes a risk-based approach.

There’s a 24/7 emergency and out-of-hours callout. Ring us if the fan fails and we will arrange a visit.

Yes. You deal with one contact for every site in our area, and visits can be set on a regular cycle.

Yes. Each visit ends with a written report and photos, showing what was done, anything we couldn’t reach and when the next visit is due. Kitchen extract cleans to TR19® Grease also get a certificate through the BESCA Vent Hygiene Elite portal.
Do you replace extract fans as well as repair them?
We do. A replacement is matched to the system it’s going into with a fixed price agreed before work begins.
Which sectors do you work in?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, as well as food production and leisure sites.
Part by part
Roof and wall-mounted fans
An external fan faces the weather as well as the grease. Corrosion of housings and fixings is common.
Motors and bearings
Rumbling and grinding typically come from the bearings. We diagnose whether it’s the bearings or the motor itself and then recommend the fix.

Looking after it afterwards
How long the results last depends on use and care. Here’s what we suggest:
- Note when the fan trips or cuts out
- Don’t turn the fan down to hide a noise
- Tell us about a new rattle or whine right away
- Save our number for the 24/7 emergency line
Listen to the fan over the next few weeks. A new noise or vibration is worth reporting early, so it can be looked at before it grows.
Noise is usually the first sign of a fan problem. Getting it checked now means a planned repair instead of a breakdown at the worst moment.
How the visit works
Before we leave, we walk the area with whoever is on site. Anything we couldn’t reach or that needs attention is pointed out there and then, and the same goes into the written report. All told, the work takes an hour or two to diagnose, then longer if parts or a new fan are needed. For a job in Grahame Park, tell us about loading bays, permits, lifts and roof access when you book.
- 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.
- The impeller, bearings, belts or drive, motor and mounts are all inspected.
- You get our diagnosis and a fixed quote to repair or replace.
- We fix or replace the fan, then test it running before we leave.
Before we arrive
