About our extract fan repair in North Mymms
Across North Mymms, we deal with fan faults of every kind, from a squeal at start-up to a fan that won’t run at all. We find the cause, give you a fixed price and fix it, or the fan is replaced if repair doesn’t make sense. If you’re dealing with a knocking noise from the extract fan and a belt-driven fan that squeals, we can help.
Somewhere as small as North Mymms, a kitchen extract fan might serve a pub, a school, a care home or a hall kitchen. When one fails, the cooking stops, and our 24/7 emergency line covers rural addresses too.
The sign-off is always in writing: a dated report with photos of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

North Mymms questions
Is there an emergency callout for extract fans in North Mymms?
North Mymms is covered, and our emergency callout runs 24/7. Phone 0345 646 2711 and we will talk through the fault and access. A photo of the fan’s rating plate helps.
Who would carry out a food hygiene inspection at a kitchen in North Mymms?
Food hygiene inspections in North Mymms are carried out by Welwyn Hatfield council. Inspections are risk-based, so a visit can come at any time, including the week a fan stops.
Can we book visits on a schedule?
Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. The report from each visit recommends the next date.
Is it worth cleaning the extract while you are fixing the fan?
A fan repair on its own doesn’t include the ductwork. We will tell you what we see, so you can decide whether to book a TR19 clean.
How do you keep the site clean during the work?
Floors and surfaces near the work are sheeted before we start, and waste is contained as we go. Before we leave, we tidy up and clean down.
What should go in our maintenance log?
Anything that proves the system is maintained: our reports and pictures, any certificates and your in-house logs. A single log for each site works best.
What if parts of the system cannot be reached?
They’re listed in the report, never skipped quietly. The report says which parts couldn’t be reached and why, and we can quote to improve the access.
Do you provide a certificate or report?
Yes, always. The report is dated and includes photos, and TR19® Grease cleans come with a certificate through the BESCA VHE portal. File it with your fire safety records.
For landlords and multi-site operators
We regularly work with managing agents. Send the address, what’s needed and how access works and we’ll come back with a fixed quote.
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we are happy to quote for all of it.
When to call us in North Mymms
Fixings and anti-vibration mounts work loose or perish over time. Then every vibration is passed into the duct and the building, which is where knocking and rattling often come from.
Signs it’s time to call us include:
- An overheating extract motor
- Vibration spreading from the fan into the ducts
- Weak extraction and a smoky kitchen
- A fan that won’t start at all
If you run a café or takeaway near Brookmans Park station, a failed fan in the middle of service is exactly what our 24/7 emergency line is for.

When a fan fails in North Mymms
The FSA’s food hygiene register shows about 15 restaurants, cafés and works canteens and about 5 sandwich bars and takeaways within about 1.5 miles of central North Mymms. Wherever they cook under a canopy, a failed extract fan stops the kitchen. Food hygiene inspections in North Mymms are the job of Welwyn Hatfield council’s environmental health team. Under food hygiene rules, a kitchen needs suitable and sufficient ventilation. That is one more reason not to keep cooking with a broken fan. North Mymms, about 16 miles from central London, is within our usual area. The visit is fixed around your opening hours, not ours.
If you manage a school such as Brookmans Park Primary School and the kitchen fan is getting louder, the next break is the time to deal with it. If you run a church or community hall kitchen, near Church of St Mary the Virgin or elsewhere in North Mymms, an extract fan that rarely runs can seize or fail when it’s needed.

Honest limits
An honest diagnosis matters more to us than a booking, so here’s what extract fan repair will not do:
- A greasy canopy and duct that a fan repair won’t touch
- Faults in the building’s electrical supply, which need an electrician
- A system that needs redesigning rather than repairing
Not sure which it is? You can call 0345 646 2711, or email photos and we’ll tell you honestly before booking.

Part by part
Fan controls
Supply faults are a job for an electrician. We will tell you if that is what we find so you know who to call.
Roof and wall-mounted fans
Fans are often mounted on roofs or external walls. Access affects how long a repair takes and we plan around it.
What staff can safely do
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
Staff cleaning and specialist work aren’t 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.
