About our extract fan repair in Hemel Hempstead
Extract fan repair starts with a diagnosis. Noise can come from grease on the impeller, worn bearings or a slipping belt, while a fan that won’t start may have a motor or control fault. You hear what we’ve found before any work goes ahead. The work covers belts and pulleys, fan motors and bearings, and the jobs we see most are a whining or grinding extract motor and a fan rattling in its housing.
Busy kitchens in a place like Hemel Hempstead can run their extract fans for long hours, and long hours wear belts, bearings and motors. Grease on the impeller makes it worse, throwing it out of balance.
We have 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.

When a fan fails in Hemel Hempstead
Look up Hemel Hempstead on the FSA’s food hygiene register and you will find about 108 restaurants, cafés and works canteens and about 69 takeaways in Hemel Hempstead and the streets around it, up to about 1.5 miles out. Every one of them that cooks under a canopy depends on its extract fan to keep cooking. In Hemel Hempstead, food businesses are inspected by environmental health officers from Dacorum council. Food premises are expected to have suitable and sufficient ventilation under food hygiene rules. That is one more reason not to keep cooking with a broken fan. At about 24 miles from central London, Hemel Hempstead sits well inside the area we cover. We work evenings, overnight and at weekends, so the visit fits around the site.
A fan that rarely runs, like one in a hall kitchen near St Barnabas or elsewhere in Hemel Hempstead, can seize between uses.

Hemel Hempstead questions
Can you work in Hemel Hempstead outside opening hours?
Yes, we can come after you close and finish before you open. It means the site in Hemel Hempstead keeps running as normal. When you ring 0345 646 2711 or send us an email, mention when the site is quiet.
Who carries out food hygiene inspections in Hemel Hempstead?
Kitchens in Hemel Hempstead are inspected by Dacorum council’s environmental health officers. If the extract fan has failed, it’s worth having the repair booked, and the details to hand, before an officer visits.
Where does the waste go?
We take it away at the end of the visit. While we work, it’s kept contained so the area stays clean.
Why is our extract fan so noisy?
An unbalanced, greasy impeller vibrates, which is a common cause of noise. Worn bearings, belts and loose mounts are others.
Which kinds of sites do you work on?
Any site with a kitchen or a ventilation system to look after, from a single café to a large school. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
Who has the legal duty for fire safety?
That depends on who controls the premises. Under the Fire Safety Order 2005, it’s the responsible person, which can be the employer, the owner, a landlord, an FM or a managing agent.
Do you have a 24/7 line?
Yes. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line, and we will advise on what to do next.
Do you provide a certificate or report?
Yes. It’s your proof that the work was done: a written, dated record with photos of what we did and anything we couldn’t access.
The process
We start by comparing what we find with the survey or your pictures. Anything unexpected is raised with you before we go further. After that, the work takes part of a day for most faults, with a return visit if parts have to be ordered. Where a site in Hemel Hempstead has more than one system, we can take them one at a time to keep the rest running.
- We take details of the symptoms and book a time that suits the kitchen.
- We isolate the fan before touching it.
- We diagnose the fault, checking the controls as well as the fan.
- A fixed quote for the repair or replacement follows.
- We fix the fault and run the fan to check it.
Before we arrive
- Plan for cooking equipment or plant to be off before we arrive
- Name a contact who can let us in at the agreed time
- Agree a time when the area can be out of use
How to get a quote
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, you get a fixed price before work begins.
Advice
Landlords, agents and facilities managers
We also work for facilities teams across offices, schools and healthcare across Hertfordshire. Work can be phased by floor, building or site to keep disruption down.
Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, ready to show insurers, fire officers or EHOs.
What your team can do, and what needs us
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
In-house cleaning and specialist cleaning do different jobs. 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.
Part by part
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 explain why.
Motors and bearings
Rumbling and grinding usually come from the bearings. We diagnose whether it’s the bearings or the motor itself before recommending a fix.
What happens if it’s left?
It can be tempting to turn the fan down to quieten it. It hides the symptom and weakens the extract, and the fault carries on developing. A proper diagnosis in Hemel Hempstead gets to the real cause. A regular plan for a site in Hemel Hempstead spreads the work out and keeps every system on track.
One small site or a whole estate, we price it on the same basis: the work involved, the access and the timing. The price is fixed before work begins.

What we are called out for in Hemel Hempstead
Any kitchen that cooks for long hours works its fan hard, in Hemel Hempstead or anywhere else. On belt-driven fans, belts stretch, crack and start to slip, so the fan squeals or turns more slowly.
The symptoms we are asked about most are:
- A fan that keeps cutting out
- A squealing belt on start-up
- A fan that will not start at all
- A whining or grinding extract motor
If you run a school kitchen, at a school such as Broadfield Academy or nearby, a fan that’s getting noisy is best repaired in the holidays before it fails in term.

Keeping the system healthy
Good habits slow the build-up between visits. Our tips:
- Keep the area around the fan controls clear
- Do not wait for a noisy fan to stop
- Write down when the fan misbehaves
- Make sure every filter is in place and clean
Where parts need ordering, we explain what that means for the kitchen until we return. The fan is completed on a return visit outside your busiest hours.
Regular TR19 cleaning includes the extract fan. A clean impeller stays in balance and that means less wear.
