About our extract fan repair in Berkhamsted
Everything a kitchen extract does depends on the fan. When it starts to rattle, hum or slow down, the cooking area soon fills with heat and fumes. Our engineers track down the fault and fix it, by repairing the fan or replacing it. The work covers kitchen extract fans, fan motors and roof and wall fans, and common reasons people get in touch are vibration spreading from the fan into the ducts and a fan running too slowly to clear the kitchen.
In a town like Berkhamsted, a failed fan usually means a closed kitchen. That is why our emergency line runs 24/7.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

How the visit works
Everything the job needs comes with us, including protection sheets, the right tools and access kit. You only need to give us clear access and switch off what needs to be off. The visit takes a few hours for most repairs, longer for a full fan replacement. In a town like Berkhamsted, we usually work after closing or on a quiet day, so the site opens again on time.
- We start with the symptoms, such as rattling, humming, slow running or a fan that won’t start.
- 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.
- We fix or replace the fan, then test it running before we leave.
How to prepare
- Let us know about permits to work or site inductions
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Let us know when the site is closed or quiet
Getting a quote
Some systems can be priced from pictures; others need a survey. 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.

Staff cleaning versus specialist work
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.
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
Do you need extract fan repair in Berkhamsted?
Fan bearings do not last for ever, especially in a hot, greasy airstream. Worn bearings whine, rumble or grind, and if they’re left they can seize.
What we are most often called out for:
- A knocking noise from the extract fan
- Poor airflow at the canopy
- An overheating extract motor
- Vibration spreading from the fan into the ducts
If you cook near Berkhamsted station, long trading hours wear fan belts and bearings, so noise and vibration are worth reporting early.
Questions to ask before you book
- Whether the quote shows VAT
- What insurance they carry
- Whether the whole system is included, or only the parts that are easy to reach
- When the next visit should be, and why
Why deal with it now?
Weak extraction leaves heat, smoke and fumes in the kitchen. Staff work in hotter, steamier air, and more grease settles where it shouldn’t. In a town like Berkhamsted, a problem caught early is a planned visit, not an emergency.
One small site or a whole estate, we price it on the same basis: the work involved, the access and the timing. You’ll have a fixed price before work begins.

Between visits
Think of this as the after-treatment advice, short and simple:
- Avoid lowering the speed to quieten a fault
- Note when the fan trips or cuts out
- Report new noises from the fan early
- Keep the fan on a planned cleaning cycle
Grease on the fan normally means grease in the duct as well. We can book a TR19® clean of the whole extract, with a certificate and photo report.
A scheduled maintenance plan keeps the whole system on a regular cycle, which means the fan is seen regularly and wear is caught earlier.
When something else is needed
We won’t sell you work that doesn’t address the problem, so here are the limits:
- Gas interlock faults that a Gas Safe registered engineer must deal with
- Problems with the electrical supply to the fan (an electrician’s job)
- A greasy canopy and duct that a fan repair will not touch
If in doubt, call us on 0345 646 2711, or send details by email and we’ll say what we think.
Parts of the system we cover

When a fan fails in Berkhamsted
The FSA’s food hygiene register shows about 44 restaurants, cafés and canteens and about 13 sandwich bars and takeaways in and around Berkhamsted, 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 Dacorum council inspect food businesses in Berkhamsted. Food premises are expected to have suitable and sufficient ventilation under food hygiene rules. Getting the fan running again is the priority. Berkhamsted is about 27 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.
School kitchens cannot easily serve lunch without extraction, so if you look after one at a school like St Thomas More Roman Catholic Voluntary Aided Primary School, fix a failing fan before term starts. If you run a church or community hall kitchen, near Church of All Saints or elsewhere in Berkhamsted, an extract fan that rarely runs can seize or fail when it’s needed.

Berkhamsted: your questions answered
What if my kitchen extract fan stops in Berkhamsted at night?
We run a 24/7 emergency line for failed extract fans, and Berkhamsted is part of our area. Phone 0345 646 2711 and we’ll talk through the fault and access. If you can, stop cooking until the fan is checked.
Which council inspects kitchens in Berkhamsted?
That’s Dacorum council, whose environmental health officers carry out food hygiene inspections in Berkhamsted. 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 contain it and take it with us. We collect grease, debris and waste water as we go, so it doesn’t spread.
Which kinds of sites do you work on?
Any site with a kitchen or a ventilation system to look after, from a small pub to a hospital. We work with hotels, schools, care homes, offices, retail and leisure sites.
Do you survey before quoting?
Yes. We always survey first, from your pictures and details, or with a visit where needed. A fixed quote follows.
Can one contract cover all our sites?
Yes. We work across South East England and London, so sites at different addresses can be planned together as one programme. Every site has its own report.
Are you accredited?
We hold CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
Do you recommend a next date?
Yes. Every report includes a recommended date for the next visit, based on what we found and how the system is used.
Multi-site and managed buildings
Multi-site operators often want one contractor and one number. We cover South East England and London, so a run of sites can go into one programme and kept on a regular cycle.
When the building owner and the occupier are different, the lease normally sets out who maintains what. We are happy to deal with either side, and the report can go to both.
