Extract fan repair and replacement in Northwood, Greater London
Repair and replacement of kitchen extract fans, fan motors and worn fan parts for Northwood, with a survey first and a report with pictures at the end. Call for a fixed quote.
- Vibration spreading from the fan into the ducts
- Weak extraction and a smoky kitchen
- A humming noise from the fan motor
How the job changes from site to site
Motors and bearings
The motor and its bearings work hardest. Heat, grease and long running hours all wear them.
Impellers and housings
Where an impeller is bent or corroded, cleaning will not help. It may need replacing, or the fan may need replacing as a whole.
How we handle extract fan repair in Northwood
Working on a fan in Northwood means switching the extract off first, so the job is fitted around the kitchen’s hours. We can work in the evening, overnight or at the weekend and there’s a 24/7 emergency line if the fan fails while you are cooking. If you have a fan shaking on its mountings and a motor that trips out or overheats, we can put it right, from belts and pulleys, kitchen extract fans and bearings onwards.
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.
Think of the report as the system’s health record: a dated account with pictures of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

Managing agents and facilities teams in Northwood
Managing agents often deal with us directly. Send the address, what’s needed and how access works and we’ll come back with a fixed quote.
Whether it’s one building or many, you get the same standard: a survey first, a fixed quote, the work timed around the site and a report with pictures.
What affects the quote in Northwood
A fixed price needs a few facts first. We look at:
- How many systems or sites are involved
- Access, including roofs, risers and ceiling voids
- The times the site is available
- Any permits to work or inductions
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you are unsure, call us on 0345 646 2711 or email us and we’ll give you an honest view and a fixed quote.
Asking for a quote
When you contact us, it’s useful to have:
- A few general shots of the system
- The site address and the type of premises
- Problems your staff have spotted
- Close-ups of filters, grilles, hatches or access panels
Getting a quote does not take long. Call or email with a few details and you will normally have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.
What we do, step by step
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 it goes on the report too. All told, the work takes part of a day for most faults, with a return visit if parts have to be ordered. In Northwood, as across London, we usually work overnight or at weekends and hand the site back ready to open.
- First, you tell us the symptoms: noise, shaking, weak extraction or no power.
- The fan is isolated and opened up so we can see inside.
- Each part is checked in turn: motor, bearings, drive, impeller and fixings.
- We explain the fault and give you a fixed price for the fix.
- The repair or replacement is carried out and the fan is run and checked.
Getting ready for the visit
- Let us know about parking and loading
- Dig out any earlier paperwork for the system
- Tell us the best time to work, such as after service or at a weekend

Northwood: your questions answered
What if my kitchen extract fan stops in Northwood at night?
Northwood is covered, and our emergency callout runs 24/7. The number to ring is 0345 646 2711. Details of the make and model help us plan the repair.
Who inspects food businesses in Northwood?
Kitchens in Northwood are inspected by Hillingdon council’s environmental health officers. A note of when the fan failed and when it was fixed shows the problem was dealt with.
Can you set up regular visits?
Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. The report from each visit recommends the next date.
Do we need to close while you work?
Not typically. Out-of-hours visits keep the disruption down. Larger jobs can be phased over several visits so parts stay in use.
Do you look at the system first?
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.
Should the fan be cleaned as well as repaired?
A repair deals with the fan, not the grease in the rest of the system. If there’s grease on the fan, a full TR19® clean is worth booking and we can plan the two together.
How do you keep the site clean during the work?
With sheeting and covers, before anything else happens. We keep the work contained and leave the area clean.
How long does an extract fan repair take?
It depends on the fault, but as a guide it takes a few hours for most repairs, longer for a full fan replacement. You will know more once we’ve found the fault.
When something else is needed
We will always give you a straight diagnosis, so here’s what this work can’t put right:
- A greasy canopy and duct that a fan repair won’t touch
- Wiring and supply faults beyond the fan itself
- Problems with the gas supply or its interlock valve
Not sure which it is? You can phone us on 0345 646 2711 or drop us a line and we will tell you honestly.

Do you need extract fan repair in Northwood?
Fan bearings do not last for ever, especially in a hot, greasy airstream. As they wear, you hear a whine or a rumble, and if they’re left they can seize.
It’s time to book a visit if you see:
- A failed fan that needs a replacement
- A fan shaking on its mountings
- An extract fan that rattles or knocks
- A fan running too slowly to clear the kitchen
For school kitchens, at schools like Frithwood Primary School for example, a planned fan repair in the holidays avoids losing lunches in term time.

Extract fans in Northwood
Look up Northwood on the FSA’s food hygiene register and you will find about 51 restaurants, cafés and works canteens and about 26 sandwich bars and takeaways in and around Northwood, up to about a mile and a half out. Wherever they cook under a canopy, a failed extract fan stops the kitchen. Environmental health officers from Hillingdon council inspect food businesses in Northwood. Food premises are expected to have suitable and sufficient ventilation under food hygiene rules. Getting the fan running again is the priority. We ask about access first for a London fan job, because roofs and basements need planning.
Hall kitchens near Emmanuel Church, or anywhere around Northwood, often use their fans only now and then, and an idle fan can stick.

What staff can safely do
Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
