- An extract fan that has stopped working
- A knocking noise from the extract fan
- A failed fan that needs a replacement
Looking after it afterwards
Here’s the after-treatment advice, short and simple:
- Make sure every filter is in place and clean
- Don’t wait for a noisy fan to stop
- Keep access to the fan controls unobstructed
- Do not turn the fan down to hide a noise
If parts have to be ordered, we tell you how the kitchen can carry on in the meantime. We then come back and fit them outside your busiest hours.
A slipping belt or a loose mount is a small job. Ignored, they can lead to bigger failures so early attention pays.
Extract fan repair for kitchens and businesses in Thorley
Grease is hard on extract fans. Deposits on the impeller throw it out of balance and the vibration wears out bearings and fixings. That is why we check the grease whenever we work on a fan and can arrange a TR19® clean of the whole system at the same time. If you have a dead fan motor and a fan running too slowly to clear the kitchen, we can put it right.
In a small place like Thorley, fans are often on an outside wall or roof, open to wind and rain. That, with the grease, is hard on motors and bearings.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.

Why act early in Thorley
An overloaded motor is under constant strain. That shortens its life and a burnt-out motor is a bigger job than a worn belt. Early attention keeps the cost and disruption down. Rural sites can’t always move to another kitchen or room when something fails.
Working hours, access and the scale of the site can all change the price. Each of those is built into the quote, and the price is fixed before work begins.
Why us?
- In business since 2009
- Every job surveyed first
- Photo reports with every job
- Fixed quotes, typically within one working day

Common problems we fix in Thorley
Some faults are in the controls rather than the fan. Speed controllers, isolators and wiring can all fail so we check the controls before blaming the motor.
Keep an eye out for any of the following:
- An extract fan that rattles or knocks
- A fan that whines, hums or grinds
- A fan shaking on its mountings
- A squealing belt on start-up
School kitchens cannot easily serve lunch without extraction, so if you look after one at a school like Richard Whittington Primary School, fix a failing fan before term starts.

What extract fan repair looks like in Thorley
Food Standards Agency records list about 15 restaurants, cafés and canteens and about 9 sandwich bars and takeaways in and around Thorley, up to about a mile and a half out. Those that cook under a canopy rely on a fan that runs every hour they’re open. At about 26 miles from central London, Thorley sits well inside the area we cover. We work evenings, overnight and at weekends, so the visit fits around the site. It’s East Hertfordshire council that sends environmental health officers to food businesses in Thorley. Food hygiene rules expect food premises to have suitable and sufficient ventilation. Getting the fan running again is the priority.
Hall kitchens near Parish Church of St James the Great, or anywhere around Thorley, often use their fans only now and then, and an idle fan can stick.

Common questions in Thorley
Do you cover smaller places like Thorley?
Yes. Thorley is within the area we cover across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Who inspects food businesses in Thorley?
Kitchens in Thorley are inspected by East Hertfordshire council’s environmental health officers. An officer may ask how the kitchen is ventilated, so keep repair records with your maintenance file.
Can you supply and fit a replacement fan?
Yes. If repair is not sensible, we replace the fan. The replacement has to suit the ductwork and the cooking before recommending a unit.
How far ahead should we book?
For planned work, earlier is better, especially if the next clean or test is due soon. Emergencies are different, because our line is open 24/7.
What about areas you cannot get to?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, which we can install.
How much does an extract fan repair cost?
Every fan job is priced once we know the fault. A belt and a new fan are very different jobs so the first step is a diagnosis.
What’s TR19?
BESA’s ventilation hygiene specification, with two parts that matter most here: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t legislation, but it’s the standard people check against.
How much time does a fan repair need?
Typically, a fan repair takes anything from an hour or two to a full visit, depending on the fault. Where parts need ordering, we’ll explain the timescale.

How the job changes from site to site
Impellers and housings
The fan housing collects grease too. We check both, and cleaning can form part of the repair.
Roof and wall-mounted fans
An external fan’s rattle can be heard outside. It’s often down to loose mounts or worn bearings.
How the visit works
We’re used to working while the site is closed. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. On site, the work takes an hour or two to diagnose, then longer if parts or a new fan are needed. In a small place like Thorley, the journey is planned ahead and the visit arranged around the site’s hours.
- First, you tell us the symptoms: noise, shaking, weak extraction or no power.
- With the fan safely isolated, we open it up for a proper look.
- Each part is checked in turn: motor, bearings, drive, impeller and fixings.
- We explain the fault and give you a fixed price for the fix.
- The repair or replacement is carried out and the fan is run and checked.
Before we arrive
- Plan for cooking equipment or plant to be off before we arrive
- Tell us about site rules, permits or sign-in
- Clear the space around the work
