About our extract fan repair in Sopwell
Wherever your kitchen is in Sopwell, fan work means the extract has to be isolated, so the job is fitted around the kitchen’s hours. We can work in the evening, overnight or at the weekend, and a fan that dies mid-service can go straight to our 24/7 line. Common call-outs are for weak extraction and a smoky kitchen and a fan rattling in its housing, on fan housings, fan motors and kitchen extract fans.
In a place like Sopwell, extract fans are often older units on a wall or roof. An older fan that fails may be better replaced than repaired.
Duct Doctor has been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

In-house cleaning or a specialist?
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
FAQs for Sopwell
Who would carry out a food hygiene inspection at a kitchen in Sopwell?
In Sopwell, it’s St Albans City council that carries out food hygiene inspections. A note of when the fan failed and when it was fixed shows the problem was dealt with.
Can the work in Sopwell be done at night or at weekends?
Yes, nights and weekends are routine for us. Your customers, staff or residents in Sopwell needn’t be disturbed. Just call 0345 646 2711 or use the quote form with your opening times and we will plan around them.
Can one contract cover all our sites?
Yes. Send the list of sites and the work at each and we will quote them together.
Can we book visits on a schedule?
Yes, of course. Send details of the systems and how they’re used and we will propose a schedule with a fixed quote.
What happens if you cannot reach some of it?
They’re marked on the report. Often the fix is extra access, such as new panels in ductwork, which we can install.
Do you recommend a next date?
Yes. The recommended date is on the report. BESA’s minimum intervals for kitchen extracts range from 3-monthly for heavy use to 12-monthly for light use, while fire dampers are tested at least annually.
What accreditations do you have?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We’ve been trading since 2009 and we are fully insured.
Is Sopwell in your area?
Yes. We work across Greater London, Surrey, Kent, Sussex, Hampshire, the Isle of Wight, Berkshire, Buckinghamshire, Oxfordshire, Hertfordshire and Essex, Sopwell included.
Landlords, agents and facilities managers
For anyone managing more than one site, we can schedule visits across all of them on one quote. Each site gets its own report and pictures, so records stay tidy.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, 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.
What we do, step by step
The first job on site is protection: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. It takes a few hours for most repairs, longer for a full fan replacement, and we clear up before we go. Visits to a place like Sopwell are planned ahead, so we arrive with what the survey says the job needs.
- We ask what the fan is doing, from noise and vibration to a full stop.
- The fan is isolated and opened up so we can see inside.
- We check the motor, bearings, drive, impeller and mountings.
- We explain the fault and give you a fixed price for the fix.
- Once the work is done, we run the fan and check it’s steady and quiet.
Before we arrive
- Name a contact who can let us in at the agreed time
- Plan for cooking equipment or plant to be off before we arrive
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
Get a fixed quote
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, you get a fixed price before we start.

Different parts, different methods
Fan controls
Controls are checked as well as the fan itself since the motor is not always to blame.
Belt-driven fans
Belt-driven fans have a motor that turns the impeller through belts and pulleys. Belts wear, stretch and slip, and pulleys and bearings need checking too.
What a clean will not put right
To be straight with you, some problems need a different fix:
- Faults on the gas side of an interlock system, which need a Gas Safe registered engineer
- Smells from the discharge that need odour control equipment
- Faults in the building’s electrical supply, which need an electrician
Not sure which it is? You can call us on 0345 646 2711 or use the quote form and we’ll tell you honestly before you book.

Looking after it afterwards
How long the results last depends on use and care. Here’s what we suggest:
- Write down when the fan misbehaves
- Book regular TR19 cleaning, which includes the fan
- Make sure every filter is in place and clean
- Keep access to the fan controls unobstructed
Clean filters help a repaired fan stay that way. Less grease on the impeller means less wear and the quieter it runs.
When filters block, the fan works harder. Changing or cleaning them on time takes load off the motor and protects the motor.
Extract fan repair around Sopwell
There are about 147 restaurants, cafés and canteens and about 41 sandwich bars and takeaways within roughly a mile and a half of the centre of Sopwell, according to the Food Standards Agency’s register. Wherever they cook under a canopy, a failed extract fan stops the kitchen. About 19 miles out from central London, Sopwell is part of the South East area we work across. A survey and a fixed quote come first, then the visit at a time that suits you. Food hygiene inspections in Sopwell are the job of St Albans City council’s environmental health team. Food hygiene rules expect food premises to have suitable and sufficient ventilation. A kitchen without a working fan has a problem to fix quickly.
Occasional-use kitchens, such as a hall kitchen near St. Julian's Church or elsewhere in Sopwell, are where a stiff or seized fan can turn up. School kitchens can’t easily serve lunch without extraction, so if you look after one at a school like Mandeville Primary School, fix a failing fan before term starts. For kitchens close to St Albans Abbey station, a fan that stops mid-service needs fixing fast, and our emergency line runs 24/7.

Why act early in Sopwell
An overloaded motor is under constant strain. That shortens its life, and when it finally fails, it may take other parts with it. Catching it early keeps the repair small. Even a site near Sopwell that’s only busy part of the week needs its system checked on a schedule.
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. Ask for a fixed quote and we’ll go through it with you.
