Extract fan repair in Coleman Green, done properly
If an extract fan in Coleman Green is struggling or has stopped, we diagnose the fault and send you a fixed quote to repair or replace it. When the fan gives up mid-service, our 24/7 emergency line is there. The work covers bearings, fan motors and kitchen extract fans, and common reasons people get in touch are a worn or slipping fan belt and an overheating extract motor.
Somewhere as small as Coleman Green, a kitchen extract fan might serve a pub, a school, a care home or a hall kitchen. A failed fan stops the kitchen, and our 24/7 emergency line covers rural addresses too.
For insurers and inspectors, the record counts. That’s why every job is written up in a report with pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

How the job changes from site to site
Roof and wall-mounted fans
An external fan faces the weather as well as the grease. Corrosion of housings and fixings is common.
Fan controls
Speed controllers and isolators sit between the supply and the fan. When they fail, the fan may not start or may run at the wrong speed.
Between visits
A little care between visits keeps the system in better shape. Our advice:
- Make sure staff know who to call if the fan fails
- Keep the grease filters clean and fitted
- Get a noisy fan checked rather than slowed down
- Don’t cook with gaps in the filter bank
We run the fan and check it’s steady before we go. We explain the fault and the fix along with anything else that needs watching.
A fan that is starting to make noise is giving you a warning. Booking a check at this stage keeps it a planned job instead of a breakdown at the worst moment.
What we do, step by step
Night work is normal for us. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. The visit itself takes a few hours on site, depending on the fault and the access to the fan. Pictures of the system and its access let us plan the work in Coleman Green before we set off.
- First, you tell us the symptoms: noise, shaking, weak extraction or no power.
- Power to the fan is isolated before we open the housing.
- Each part is checked in turn: motor, bearings, drive, impeller and fixings.
- 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
- Tell us the best time to work, such as after service or at a weekend
- Move anything stored near the system
- Dig out any earlier paperwork for the system
Get a fixed quote
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.
Advice
What a clean will not put right
To be straight with you, some problems need a different fix:
- Faults on the gas side of an interlock system, which need a Gas Safe registered engineer
- Odour complaints that need filtration rather than a fan repair
- An extract system that was undersized from the start
If you are not sure, just call 0345 646 2711, or send details by email and we’ll give you a straight answer.
Parts of the system we cover
- Belts and pulleys
- Kitchen extract fans
- Bearings
- Roof and wall fans
- Fan housings
- Fan motors
When to call us in Coleman Green
Some faults are in the controls rather than the fan. Speed controllers, isolators and wiring can all fail so we check the controls before blaming the motor.
The symptoms we’re asked about most include:
- A fan that keeps cutting out
- A fan shaking on its mountings
- A dead fan motor
- A squealing belt on start-up
Around Coleman Green, a failed fan can be reported day or night on our 24/7 line.
Questions to ask before booking
- If they look at the system before pricing
- What insurance they carry
- Exactly which parts of the system are covered
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
Leave it or put it right?
Left alone, vibration spreads its damage. It loosens fixings, strains duct connections and wears the housing and the eventual repair is larger. A planned visit to Coleman Green is easier to arrange than an emergency callout.
The cost depends on how big the system is, the condition it’s in and how easy it is to reach. We give you a fixed price before any work starts, so you know where you stand.
What you get with us
- We’re fully insured
- Accredited under CHAS and SafeContractor, with ISO 9001
- Work around your opening hours, with 24/7 emergency cover
- Every job surveyed first

When a fan fails in Coleman Green
There are about 11 restaurants, cafés and canteens in and around Coleman Green, up to about a mile and a half out, according to the Food Standards Agency’s register. A kitchen with a dead extract fan gets hot and smoky fast, and kitchens like these feel it at once. Coleman Green is about 22 miles from central London, well within the area we cover across London and the South East. The visit is fixed around your opening hours, not ours. In Coleman Green, food businesses are inspected by environmental health officers from St Albans City council. A kitchen with no working extract can fall short of the suitable and sufficient ventilation food hygiene rules expect. So a failed fan is worth fixing before the next service, not the next month.
If you manage a school such as Beech Hyde Primary School and Nursery and the kitchen fan is getting louder, the next break is the time to deal with it.

What makes a kitchen extract fan rattle or whine?
Noise normally comes from grease build-up, bearings, belts or loose fixings. Each sounds a little different, and we diagnose it on site.
How do you protect the area?
By covering it before any work starts. We keep the work contained and leave the area clean.
Does a faulty extract fan always need replacing?
That depends on what we find. After diagnosing, we explain whether it can be repaired and quote a fixed price for the option you choose.
Can one contract cover all our sites?
Yes. Tell us the addresses and what each needs and we will quote them together.
Is there a survey before the work?
Yes. We always survey first, from your photos and details, or with a visit where needed. Then you get a fixed quote.
What affects the cost of extract fan repair
There’s no set price list, because no two systems are the same. What we look at:
- The condition of the system
- How many systems or sites are involved
- The times the site is available
- The scale of the work
We do not list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we will explain what it covers.
What to send for a quote
Photos and a few facts are often enough to price the work. Useful things to send:
- The postcode and the type of business
- Your opening hours and when the area is out of use
- The paperwork from the last visit, if you have it
- Detail shots of panels, filters and grilles
Quoting starts with a diagnosis, from your pictures and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work, before we start.
