Extract Fan Repair in Dartmouth Park
Professional extract fan repair in and around Dartmouth Park, timed so the site keeps working and finished with a written report and photos.
- An extract fan that has stopped working
- A whining or grinding extract motor
- A worn or slipping fan belt
What staff can safely do
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
About our extract fan repair in Dartmouth Park
Grease is hard on extract fans. Deposits on the impeller throw it out of balance, which shakes the bearings and mountings. So when we repair extract fan, we look at the grease too, and a full TR19® clean can be booked alongside. We are often asked to deal with a fan that whines, hums or grinds and a belt-driven fan that squeals, across roof and wall fans, bearings and kitchen extract fans.
London extract fans often sit on rooftops, exposed to the weather as well as the grease, and in time, bearings, belts and motors fail. Noise and vibration are worth reporting before the fan stops.
The sign-off is always in writing: a written report, dated and illustrated with photos, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

When to call us in Dartmouth Park
Not every problem is mechanical. Speed controllers, isolators and wiring can all fail so we check the controls before blaming the motor.
Any of these means the system needs a check-up:
- A fan that keeps cutting out
- A fan that will not start at all
- An extract fan that rattles or knocks
- Vibration spreading from the fan into the ducts
If you look after a church or hall kitchen near Church of St Mary Brookfield, or anywhere in Dartmouth Park, test the extract fan before a big event rather than on the day.

What affects the cost of extract fan repair
Sites vary more than people expect. The main factors:
- One-off work versus a regular cycle
- When the work can happen, such as evenings, overnight or weekends
- Whether several sites go on one quote
- Any permits to work or inductions
No two sites are the same, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all make a difference.
What to send for a quote
A few details help us quote accurately. When you get in touch, it helps to send:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Your opening hours and when the area is out of use
- The postcode and the type of business
There’s no standard price list, because every site is different. Instead, we look at your site first, from pictures or a survey, and then send you a fixed quote. To get going, call us on 0345 646 2711 or drop us a line.
Aftercare tips
Results last longer with the right care. We suggest:
- Keep the emergency number where staff can see it
- Never run the extract with filters missing
- Avoid lowering the speed to quieten a fault
- Keep a record of any trips or stoppages
Before we leave, the fan is run and checked. We explain the fault and the fix, and anything else we noticed is pointed out.
A slipping belt or a loose mount is a small job. Left for months, they can damage the motor or bearings so early attention pays.
What happens on the day
Protection comes first: floors, worktops and anything near the work are covered. Then we make the system safe and start. It takes anything from an hour or two to a full visit, depending on the fault, and the area is cleaned down before we leave. A name and number for whoever controls access to the building in Dartmouth Park saves time on the night.
- We start with the symptoms, such as rattling, humming, slow running or a fan that won’t start.
- The fan is isolated and opened up so we can see inside.
- Each part is checked in turn: motor, bearings, drive, impeller and fixings.
- You hear what’s wrong and what it will cost, with a fixed quote, before we go ahead.
- We fix or replace the fan, then test it running before we leave.
How to prepare
- Tell us where we can park and unload
- Mention any sign-in, permit or induction we need
- Plan for cooking equipment or plant to be off before we arrive
Ask for a quote
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, the quote is fixed before any work is booked.

Common questions in Dartmouth Park
Can parking be tricky for a job in Dartmouth Park?
London parking can be tight, so details of loading bays and permits help. Night visits tend to make loading easier on London streets.
What if my kitchen extract fan stops in Dartmouth Park at night?
Extract fan emergencies in Dartmouth Park are covered around the clock. Use 0345 646 2711, our emergency number, at any time. If you can, stop cooking until the fan is checked.
Is there a survey before the work?
Yes, always. We diagnose before we treat: the survey tells us what the system needs and how to reach it, and the quote is based on that.
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 we start.
How long does an extract fan repair take?
That depends on what’s wrong, but most jobs take a few hours for most repairs, longer for a full fan replacement. We will give you a better idea once we have diagnosed it.
Who has the legal duty for fire safety?
The law calls them the responsible person. It’s normally the employer, or whoever controls the building, and where several people have control, each can have duties. If you are not sure, check your lease and fire risk assessment.
Can you repair a fan rather than replace it?
It depends on the fault. After diagnosing, we explain whether it can be repaired, then send you a fixed quote.
Do we need to close while you work?
Not typically. Out-of-hours visits keep the disruption down. Bigger sites can be done in stages to keep things running.
What extract fan repair cannot fix
Some problems need a different service or another trade:
- Wiring and supply faults beyond the fan itself
- Odour complaints that need filtration rather than a fan repair
- Faults on the gas side of an interlock system, which need a Gas Safe registered engineer
If you’re not sure, just call us on 0345 646 2711, or send details by email and we will give you a straight answer.

Extract fans in Dartmouth Park
The FSA’s food hygiene register shows about 636 restaurants, cafés and works canteens and about 305 sandwich bars and takeaways within about 1.5 miles of central Dartmouth Park. Those that cook under a canopy rely on a fan that runs every hour they’re open. In Dartmouth Park, food businesses are inspected by environmental health officers from Camden council. Food hygiene rules expect food premises to have suitable and sufficient ventilation. That is one more reason not to keep cooking with a broken fan. London extract fans are often at the end of long duct runs, on roofs or in basements.
If you cook near Gospel Oak station, long trading hours wear fan belts and bearings, so noise and vibration are worth reporting early. For school kitchens, at schools like Acland Burghley School for example, a planned fan repair in the holidays avoids losing lunches in term time.

For landlords and multi-site operators
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
