Hertfordshire · Extract fan repair and replacement
Nether Street extract fan repair
Extract fan repair for Nether Street, from a team that has been trading since 2009. Evenings, overnight and weekends, plus a 24/7 emergency line.
- An extract that vibrates through the ductwork
- An extract fan that rattles or knocks
- A squealing belt on start-up
Honest limits
In fairness, there are a few things this work will not fix:
- Grease throughout the ductwork, which needs a full TR19 clean
- Gas interlock faults that a Gas Safe registered engineer must deal with
- Faults in the building’s electrical supply, which need an electrician

Extract fan repair for kitchens and businesses in Nether Street
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 with a repair or a replacement. If you have a belt-driven fan that squeals and an overheating extract motor, we can put it right.
In a small place like Nether Street, fans are often on an outside wall or roof, open to wind and rain. Weather and grease together wear out motors and bearings.
Each visit ends with a written report and photos, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Nether Street: your questions answered
Will you come out to Nether Street?
Yes. Villages and rural sites across the South East are part of our work, Nether Street included. Just mention lanes, gates or anything else about the site when you book.
Which council inspects kitchens in Nether Street?
Kitchens in Nether Street are inspected by East Hertfordshire council’s environmental health officers. A note of when the fan failed and when it was fixed shows the problem was dealt with.
How much does an extract fan repair cost?
The price depends on the diagnosis. After we have checked the fan, we give you a fixed price for the repair or the replacement.
Do you replace extract fans as well as repair them?
Yes, when repair does not make sense. The replacement has to suit the ductwork and the cooking so we confirm that first.
Are you fully insured?
Yes. We are fully insured, and the details are available on request.
Does a faulty extract fan always need replacing?
We look at repairing it first. If the fan is past saving, a replacement may be more sensible, and we will explain why.
What does TR19 mean?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It sets out inspection, cleaning and record keeping, and it takes a risk-based approach.
Which records should we keep?
Everything that shows the system is looked after: our reports and pictures, any certificates and your in-house logs. One maintenance log per site keeps it simple.
How it works
We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool before any work starts, and the area around the work is covered and protected. On site, it takes an hour or two to diagnose, then longer if parts or a new fan are needed. We agree a date with you, plan the drive to Nether Street and turn up when the site is quiet.
- A visit is booked, in the evening or overnight if that suits.
- The extract is switched off and the fan opened up.
- Bearings, drive, impeller, motor and mounts are inspected.
- We explain the options and quote a fixed price.
- The fan is repaired or replaced, then checked running.
Getting ready for the visit
- Mention any sign-in, permit or induction we need
- Tell us where we can park and unload
- Agree a time when the area can be out of use
Ask for a quote
There’s no standard price list, because no two systems are the same. We look at your system first, from pictures or on a visit, then send a fixed quote. To get going, call us on 0345 646 2711 or send us an email.

Staff cleaning versus specialist work
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
Multi-site and managed buildings
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
Facilities teams in offices, schools and healthcare sites book us too across Hertfordshire. Work can be phased by floor, building or site to keep disruption down.
Extract fan repair in Nether Street: local notes
The FSA’s food hygiene register shows about 3 cafés, restaurants and staff canteens across Nether Street and its immediate surroundings (about a mile and a half). Those that cook under a canopy rely on a fan that runs every hour they’re open. In Nether Street, food businesses are inspected by environmental health officers from East Hertfordshire council. Ventilation is part of food hygiene law, which expects it to be suitable and sufficient. That’s one more reason not to keep cooking with a broken fan. About 24 miles out from central London, Nether Street is part of the South East area we work across. Evening, overnight and weekend visits are all possible.
Occasional-use kitchens, such as a hall kitchen near Parish Church of St John the Baptist or elsewhere in Nether Street, are where a stiff or seized fan can turn up. Holidays are the time to replace a tired kitchen fan at schools such as Widford School, rather than mid-term.

What happens if it’s left?
A noisy fan rarely fixes itself. Worn bearings can seize without much warning and the fan may stop when you’re busiest. Sorting it while it still runs is far easier to plan. Our emergency line runs 24/7, but a planned visit to Nether Street is calmer for everyone.
What you pay depends on the size of the system, the condition it’s in and how easy it is to reach. You get a fixed price before we start, so you know where you stand.

What the work involves, part by part
Roof and wall-mounted fans
Many kitchen extract fans sit on a roof or an outside wall. Access affects how long a repair takes, so we ask about it early.
Impellers and housings
The impeller is the bladed wheel that moves the air. Grease on it throws it out of balance and make it shake.
