Staff cleaning versus specialist work
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.
Extract fan repair in Lemsford
The extract fan is what pulls smoke, heat and steam out of the kitchen. 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. If you’re dealing with a fan that whines, hums or grinds and a belt-driven fan that squeals, we can help, from kitchen extract fans, fan motors and bearings onwards.
A callout to a small place like Lemsford goes better when we know what we are looking at: photos of the fan, its rating plate and how to reach it all help.
A written report with pictures follows every visit, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

What the work involves, part by part
Motors and bearings
The motor and its bearings work hardest. Heat, grease and long running hours all wear them.
Direct-drive fans
An impeller coated in grease vibrates straight into the motor bearings. Cleaning it can cure the noise, if the bearings haven’t been damaged.
Lemsford questions
Can you come to Lemsford after we close?
Yes, nights and weekends are routine for us. Your customers, staff or residents in Lemsford needn’t be disturbed. Let us know the hours you are closed and we’ll book within them.
Who carries out food hygiene inspections in Lemsford?
Kitchens in Lemsford are inspected by Welwyn Hatfield council’s environmental health officers. An officer may ask how the kitchen is ventilated, so keep repair records with your maintenance file.
How much does an extract fan repair cost?
We price each job after finding the cause. A belt and a new fan are very different jobs, so ring 0345 646 2711, or email photos and we’ll arrange a diagnosis.
Can you look after several sites?
Yes. One number covers all your sites across London and the South East, with visits on a regular schedule.
What does TR19 mean?
A BESA specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t law, but it’s the benchmark.
What do you do to protect the area?
With sheeting and covers, before anything else happens. The work is kept contained and clean down when we finish.
Do I get a report after the visit?
Yes. Every visit ends with a written report and photos, showing what was done, anything we couldn’t reach and when the next visit is due. Kitchen extract cleans to TR19® Grease also get a certificate through the BESCA Vent Hygiene Elite portal.
Does a fan repair include cleaning the ductwork?
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.

Extract fans in Lemsford
There are about 31 restaurants, cafés and works canteens and about 7 takeaways within roughly a mile and a half of the centre of Lemsford, according to the Food Standards Agency’s register. Those that cook under a canopy rely on a fan that runs every hour they’re open. Environmental health officers from Welwyn Hatfield council inspect food businesses in Lemsford. Food hygiene rules expect food premises to have suitable and sufficient ventilation. Getting the fan running again is the priority. Lemsford is about 21 miles from central London, well within the area we cover across London and the South East. Visits are booked around your hours, evenings and weekends included.
Hall kitchens near Church of St John the Evangelist, or anywhere around Lemsford, often use their fans only now and then, and an idle fan can stick. School kitchens cannot easily serve lunch without extraction, so if you look after one at a school like Applecroft School, fix a failing fan before term starts.

- The extract is switched off and the fan opened up.

Advice
Between visits
After the visit, a few habits help the work last:
- Save our number for the 24/7 emergency line
- Report new noises from the fan early
- Keep a record of any trips or stoppages
- Make sure the isolator and controls are easy to reach
We run the fan and check it’s steady before we go. You’ll hear what we found and what we did along with anything else that needs watching.
Small faults, like a worn belt, are quick to fix. Left for months, they can damage the motor or bearings, so it’s worth acting early.
When it’s something else
Extract fan repair can’t fix everything, and we’d rather say so up front. It does not solve:
- Grease throughout the ductwork, which needs a full TR19 clean
- A system that needs redesigning rather than repairing
- Cooking smells reaching neighbours, which may need odour control
If in doubt, give us a ring on 0345 646 2711 or email us and we will say what we think before booking.

Why act early in Lemsford
A struggling motor runs hotter and works harder. Every hour of strain takes its toll and a burnt-out motor is a bigger job than a worn belt. Early attention keeps the cost and disruption down. Systems in rural buildings are often out of sight and out of mind.
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we’ll explain each part.

For landlords and multi-site operators
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
Keeping records across a portfolio is half the battle. Each visit produces a dated report with pictures, ready to show insurers, fire officers or EHOs.
