Extract fan repair for kitchens and businesses in South Mimms
We treat a failing fan much like a patient: we hear the symptoms, find the cause and put it right. The aim is steady, quiet extraction and a plain account of what we found. We’re often asked to deal with a fan that won’t start at all and a fan that keeps cutting out, across roof and wall fans, kitchen extract fans and fan motors.
In a small place like South Mimms, fans are often on an outside wall or roof, open to wind and rain. That, with the grease, is hard on motors and bearings.
Think of the report as the system’s health record: a dated account with pictures of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

How it works

The work on site takes a few hours for most repairs, longer for a full fan replacement, and the area is cleaned down before we leave. A few photos of the system help us make the most of a visit to a place like South Mimms.
- You describe the fault and we arrange a visit.
- We isolate the fan before touching it.
- We diagnose the fault, checking the controls as well as the fan.
- You get a fixed price for putting it right.
- The work is done and the fan is tested running.
Before we arrive

Advice
Why it’s worth doing now in South Mimms
In kitchens with an interlocked gas supply, no extract can mean no cooking. Without extraction, the heat and fumes build up fast, so a failing fan is worth dealing with early. Equipment tucked in a roof space or outbuilding near South Mimms rarely gets looked at unless someone books it.
No two sites are the same, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all play a part.
Why us?
- One number for every site across the South East and London
- Full insurance on every job
- Ventilation hygiene specialists since 2009
- A written report with photos after each visit

What the work involves, part by part
Motors and bearings
A grinding or rumbling noise often means worn bearings. We find out whether the bearings or the motor is at fault before recommending a fix.
Belt-driven fans
Belt drives have more moving parts than direct-drive fans. That means more to check, but often a simpler repair.
Your questions about extract fan repair in South Mimms
Can you come to South Mimms after we close?
Yes, out-of-hours work is a big part of what we do. That way a site in South Mimms does not have to lose a day’s trading. Your opening times are the first thing we ask for.
Who would carry out a food hygiene inspection at a kitchen in South Mimms?
Food hygiene inspections in South Mimms are carried out by Hertsmere council. Keeping the fan serviced is easier than explaining a broken one on inspection day.
How long will the fan be out of action?
That depends on what’s wrong, but as a guide it takes an hour or two to diagnose, then longer if parts or a new fan are needed. We will give you a better idea once we have diagnosed it.
Do you look at the system first?
Yes, always. Diagnosis comes before treatment: the survey shows what needs doing and what access we need, and the quote is based on that.
Do you provide a certificate or report?
Yes, always. The report is dated and includes pictures, plus a certificate via the BESCA Vent Hygiene Elite portal for TR19® Grease cleans. Keep it in your maintenance log.
Can you come out in an emergency?
Yes. Our emergency line runs 24/7, for problems that can’t wait. Call us any time and explain what’s happened.
Are you fully insured?
Yes. Full insurance covers our work, and we have been trading since 2009.
Do you work in South Mimms?
Yes. We work in South Mimms and across Hertfordshire, within our South East and London area. For a fixed quote, give us a ring on 0345 646 2711 or email us.

For any of them with a canopy, the extract fan is what keeps the kitchen usable. We cover South Mimms, about 15 miles from central London, as part of our work across London and the South East.

Signs you need extract fan repair in South Mimms
Over the years, mountings loosen and rubber mounts break down. The fan’s movement then travels into the ductwork and structure and that is a common source of rattles.
Keep an eye out for these warning signs:
- A humming noise from the fan motor
- An extract fan that has stopped working
- A belt-driven fan that squeals
- A fan that keeps cutting out
School kitchens can’t easily serve lunch without extraction, so if you look after one at a school like St Giles' CofE Primary School, fix a failing fan before term starts.
Questions to ask before booking
- Whether the work can be done while the site is closed
- How areas they can’t reach will be recorded
- What’s included in the scope, part by part
- Whether the quote shows VAT
Looking after it afterwards
Here’s the after-treatment advice, in brief:
- Make sure staff know who to call if the fan fails
- Keep a record of any trips or stoppages
- Tell us about a new rattle or whine right away
- Do not cook with gaps in the filter bank
Listen to the fan over the next few weeks. A new noise or vibration is worth reporting early, so it can be looked at before it grows.
A 3, 6 or 12-monthly cleaning plan brings us back at set intervals, which means the fan is seen regularly and problems are spotted sooner.
How we price extract fan repair
We quote each job individually. These are the things that affect it:
- The size of the system
- Any permits to work or inductions
- How many systems or sites are involved
- When the work can happen, such as evenings, overnight or weekends
What you pay depends on how big the system is, the condition it’s in and access to every part of it. You get a fixed price before work begins, so you know where you stand.
What we need to know
What to send for a quote:
- Any previous report or certificate
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The site address and the type of premises
- How we’d reach plant on a roof or in a plant room
Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, the quote is fixed before any work is booked.
