How we handle extract fan repair in Kingston Vale
The extract fan is what pulls smoke, heat and steam out of the kitchen. When it starts to rattle, hum or slow down, the kitchen gets hot and smoky very quickly. We find out why and put it right, by repairing the fan or replacing it. The work covers roof and wall fans, kitchen extract fans and belts and pulleys, and the jobs we see most are a dead fan motor and vibration spreading from the fan into the ducts.
Rooftop fans in London take the weather as well as the grease from below, and bearings, belts and motors wear out in the end. A fan that is noisy or vibrating is giving a warning.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

Do you need extract fan repair in Kingston Vale?
In Kingston Vale, as anywhere, long cooking days mean long hours for the fan. Belts on a belt-driven fan stretch and wear and a slipping belt means slower fan speed and weaker extraction.
Signs it’s time to call us include:
- Weak extraction and a smoky kitchen
- A whining or grinding extract motor
- A failed fan that needs a replacement
- An extract fan that has stopped working
Hall kitchens near St John the Baptist, or anywhere around Kingston Vale, often use their fans only now and then, and an idle fan can stick.

What else we do in Kingston Vale
Different parts, different methods
Direct-drive fans
Many kitchen extracts use direct-drive fans. If the motor has gone, a replacement unit is often the sensible option and we’ll talk you through it.
Belt-driven fans
Belt-driven fans have a motor that turns the impeller through belts and pulleys. Belts wear, stretch and slip, so we check the pulleys and bearings as well.
Extract fans in Kingston Vale
The FSA’s food hygiene register shows about 44 restaurants, cafés and works canteens within 1.5 miles or so of the middle of Kingston Vale. Every one of them that cooks under a canopy depends on its extract fan to keep cooking. Food hygiene inspections in Kingston Vale are the job of Kingston-Upon-Thames council’s environmental health team. Food premises are expected to have suitable and sufficient ventilation under food hygiene rules. A kitchen without a working fan has a problem to fix quickly. Lifting a replacement fan onto a London roof can need a loading slot and the building’s agreement.
School kitchens cannot easily serve lunch without extraction, so if you look after one at a school like Robin Hood Primary School, fix a failing fan before term starts.

The process
We start by comparing what we find with the survey or your pictures. If anything is different, we talk it through with the person on site before carrying on. From there, it takes part of a day for most faults, with a return visit if parts have to be ordered. Managed blocks in London often need contractors booked in ahead, and we’re happy to deal with the agent directly for a site in Kingston Vale.
- 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.
- The impeller, bearings, belts or drive, motor and mounts are all inspected.
- You get our diagnosis and a fixed quote to repair or replace.
- Once the work is done, we run the fan and check it’s steady and quiet.
Preparing for the visit
- Make sure equipment near the work can be switched off and left to cool
- Mention any parking or loading restrictions
- Arrange a key holder or contact on site

Aftercare tips
Simple habits between visits make a real difference. We recommend:
- Make sure every filter is in place and clean
- Save our number for the 24/7 emergency line
- Don’t cook with gaps in the filter bank
- Avoid lowering the speed to quieten a fault
We run the fan and check it’s steady before we go. We explain the fault and the fix, and anything else we noticed is pointed out.
Clogged filters make the fan strain. Keeping filters clean eases the strain and helps prevent overheating.
Leave it or put it right?
A noisy fan rarely fixes itself. Bearings that are left to wear can fail suddenly and the fan may stop when you are busiest. Sorting it while it still runs is far easier to plan. Planning ahead in Kingston Vale lets you pick a quiet night rather than lose a busy one.
Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered, and you’ll get one fixed quote.

How we price extract fan repair
We quote each job individually. These are the things that affect it:
- The number of sites or systems
- One-off work versus a regular cycle
- Site requirements such as sign-in and permits
- Travel, parking and unloading
When the work has to happen, how we reach it and how big the site is can all change the price. We take each of them into account and give you a fixed price before any work starts.
Asking for a quote
Before you ask for a quote, gather:
- Close-ups of filters, grilles, hatches or access panels
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Your opening hours and when the area is out of use
- A few general shots of the system
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
What a clean will not put right
In fairness, there are a few things this work won’t fix:
- Gas interlock faults that a Gas Safe registered engineer must deal with
- A system that needs redesigning rather than repairing
- Grease build-up in the rest of the extract system
If in doubt, phone us on 0345 646 2711 or drop us a line and we will say what we think.

- Fan housings

Kingston Vale questions
Who inspects food businesses in Kingston Vale?
In Kingston Vale, it’s Kingston-Upon-Thames council that carries out food hygiene inspections. An officer may ask how the kitchen is ventilated, so keep repair records with your maintenance file.
Who do I call if an extract fan fails in Kingston Vale?
Extract fan emergencies in Kingston Vale are covered around the clock. Call 0345 646 2711 and tell us what the fan is doing, or not doing. Details of the make and model help us plan the repair.
Is there a survey before the work?
Yes, always. We diagnose before we treat: the survey shows what needs doing and what access we need and the fixed quote is built on it.
Do we lose a day’s trading?
Not normally. We work when the area is out of use, such as evenings, overnight, early mornings or weekends, so you keep your normal hours.
Should the fan be cleaned as well as repaired?
Doing both together is often sensible. A TR19 clean covers the canopy, plenum, ductwork and fan and comes with a TR19 certificate and photo report.
What makes a kitchen extract fan rattle or whine?
There are several possible causes, including bearings, belts, grease and mounts. It’s worth having it diagnosed before it leads to a breakdown.
Which records should we keep?
Everything that shows the system is looked after: reports, certificates, pictures and your own cleaning or check logs. A single log for each site works best.
Do you provide a certificate or report?
Yes, on every job. The report is dated and includes pictures, and TR19® Grease cleans come with a certificate through the BESCA VHE portal. Keep it in your maintenance log.
