Extract fan repair in Queensbury
Working on a fan in Queensbury means switching the extract off first, so we plan it around your service. Evenings, overnight and weekends are all possible and there’s a 24/7 emergency line if the fan fails while you are cooking. The work covers fan housings, bearings and roof and wall fans, and people most often call us about an extract fan that has stopped working and an old fan that needs replacing.
In London, a kitchen without working extraction can’t keep cooking safely. In Queensbury, as across London, fans often sit on a roof or deep in a plant space, so access is the first thing we ask about.

Extract fans in Queensbury
There are about 164 restaurants, cafés and works canteens and about 77 sandwich bars and takeaways within 1.5 miles or so of the middle of Queensbury, according to the Food Standards Agency’s register. Those that cook under a canopy rely on a fan that runs every hour they’re open. Environmental health officers from Brent council inspect food businesses in Queensbury. Ventilation is part of food hygiene law, which expects it to be suitable and sufficient. So a failed fan is worth fixing before the next service, not the next month. In London, a fan on a roof or in a basement can take planning to reach, with parking and loading to arrange.
If you manage a school such as Glebe Primary School and the kitchen fan is getting louder, the next break is the time to deal with it.

How the visit works
We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes anything from an hour or two to a full visit, depending on the fault. Getting kit into a London building takes planning, so let us know where we can load and park in Queensbury.
- First, you tell us the symptoms: noise, shaking, weak extraction or no power.
- With the fan safely isolated, we open it up for a proper look.
- 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.
How to prepare
- Have your last certificate or report to hand
- Clear the space around the work
- Make sure someone can let us in and lock up afterwards
Getting a quote
Here’s what helps us quote: the address, the type of site and when it’s open, pictures of the system and any previous report or certificate. Then give us a ring on 0345 646 2711, or email photos.
Advice
Between visits
Good habits slow the build-up between visits. A few tips:
- Keep access to the fan controls unobstructed
- Make sure every filter is in place and clean
- Keep all filters fitted while cooking
- Save our number for the 24/7 emergency line
Grease on the fan usually means grease in the duct as well. We can book a TR19® clean of the whole extract, with a certificate and photo report.
Noise is usually the first sign of a fan problem. Getting it checked now means a planned repair rather than an emergency during service.
Do you need extract fan repair in Queensbury?
Not every problem is mechanical. Speed controllers, isolators and wiring can all fail, and a fan that won’t start isn’t always a dead motor.
Clients usually contact us after spotting one of these:
- A humming noise from the fan motor
- A motor that trips out or overheats
- A dead fan motor
- A fan worn beyond sensible repair
A fan that rarely runs, like one in a hall kitchen near All Saints Church or elsewhere in Queensbury, can seize between uses.
Questions to ask before you book
- Whether the quote shows VAT
- Whether they recommend a next date
- Whether a survey comes first
- Exactly which parts of the system are covered
Common questions in Queensbury
Does London parking affect a job in Queensbury?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Where restrictions apply in the day, an evening or overnight visit usually gets round them.
Do you work at weekends in Queensbury?
Yes, out-of-hours work is a big part of what we do. The work in Queensbury can fit around your hours. When you give us a ring on 0345 646 2711, or email photos, mention when the site is quiet.
Is there a survey before the work?
Yes. For many sites, photos and a few details are enough, while bigger or harder-to-see systems are surveyed on site.
Will you tell us when the next visit is due?
Yes. The interval depends on how much the system is used and what we find, and we explain the reasoning on the report.
Who is responsible for fire safety on the premises?
The law calls them the responsible person. That’s generally the employer or the person in control of the premises, and where several people have control, each can have duties. Your lease and fire risk assessment should make it clear.
Do you provide a certificate or report?
Yes. It’s your proof that the work was done: a written, dated record with pictures of what we did and anything we couldn’t access.
Do you have a 24/7 line?
Yes. There’s a 24/7 emergency line for anything that can’t wait until a planned visit. Call us any time and explain what’s happened.
Are you insured?
Yes, fully. CHAS and SafeContractor accreditation sit alongside it for clients who vet their contractors.
Staff cleaning versus specialist work
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That’s our job.
Staff cleaning and specialist work aren’t the same thing. 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. That part needs specialist access and equipment.
Leave it or put it right?
Fan noise tends to get worse, not better. Bearings that are left to wear can fail suddenly and the fan may stop when you’re busiest. A repair booked now is simpler than an emergency later. A building in Queensbury may have flats or offices above and alongside, and a fault in the system can affect them too.
Several systems or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at and we’ll price it together.

What affects the cost of extract fan repair
The price is fixed before any work begins. It takes into account:
- Any permits to work or inductions
- Travel, parking and unloading
- Whether we need access equipment or extra panels
- Working hours and out-of-hours timing
A single site or a whole portfolio, the quote is built the same way: what needs doing, how we get to it and when. You’ll have a fixed price before we start.
What we need to know
Photos let us diagnose from a distance. Try to include:
- A few general shots of the system
- Any symptoms, from odd noises to smells or leaks
- How we’d reach plant on a roof or in a plant room
- The paperwork from the last visit, if you have it
There’s no standard price list, because no two systems are the same. Instead, we look at your site first, from pictures or a survey, then send a fixed quote. To start, give us a ring on 0345 646 2711 or email us.
