How we handle extract fan repair in Chaulden
Not every failed fan needs replacing. Often a clean, a new belt or new bearings brings it back, and that is what we will recommend. When a fan is worn beyond sensible repair, we fit a replacement matched to the duct and the kitchen. Typical jobs include an extract that vibrates through the ductwork and a fan that keeps cutting out, on kitchen extract fans, roof and wall fans and bearings.
In a place like Chaulden, extract fans are often older units on a wall or roof. An older fan that fails may be better replaced than repaired.
Good records are part of the job. You get a written report with photos after every visit, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

Common questions in Chaulden
Who do I call if an extract fan fails in Chaulden?
Chaulden is covered, and our emergency callout runs 24/7. Call 0345 646 2711 and tell us what the fan is doing, or not doing. Let us know whether the fan is silent, noisy or tripping the power.
Do you work at weekends in Chaulden?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. Let us know the hours you’re closed and we will book within them.
Does a faulty extract fan always need replacing?
It depends on the fault. We diagnose first and tell you whether a repair is realistic, then give you a fixed quote.
Is TR19 cleaning required by law?
No. TR19® itself is not law; it’s a BESA specification. The law is the Regulatory Reform (Fire Safety) Order 2005, which makes the responsible person assess and reduce fire risk, and cleaning to TR19® is the recognised way to show grease is under control.
Does a fan repair include cleaning the ductwork?
A fan repair on its own doesn’t include the ductwork. We’ll tell you what we see, so you can decide whether to book a TR19 clean.
Do you offer maintenance contracts?
Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. Each report recommends when the next visit should be.
Who has the legal duty for fire safety?
Under the Regulatory Reform (Fire Safety) Order 2005, it’s the responsible person: often the employer, owner or occupier. In shared or managed buildings, a landlord, facilities manager or managing agent can share the duty.
Are you insured?
Yes. Duct Doctor is fully insured, and the details are available on request.
Why deal with it now?
Fan noise tends to get worse, not better. Bearings that are left to wear can fail suddenly, and that often happens mid-service. Sorting it while it still runs is far easier to plan. Systems on quieter sites still build up dirt and wear, just more slowly.
Working hours, access and the scale of the site can all change the price. Each of those is built into the quote and give you a fixed price before work begins.
What you get with us
- A written report with photos after each visit
- Trading since 2009
- A fixed price before any work starts
- Survey first, then a fixed quote

Part by part
Impellers and housings
The impeller does the work of moving air through the system. Grease on it throws it out of balance and make it shake.
Belt-driven fans
Squealing at start-up often points to a belt. Belts are checked for wear, tension and alignment and replaced if they’re worn.
How it works
At the end of the visit, someone from your team can look over the work with us. We point out anything that couldn’t be reached or needs a follow-up, and the same goes into the written report. All told, the work takes part of a day for most faults, with a return visit if parts have to be ordered. Everything the job in Chaulden needs is worked out beforehand, from the survey.
- You describe the fault and we arrange a visit.
- On site, the fan is safely isolated.
- 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.
Getting ready for the visit
- Mention any locked doors, roof access or ceiling voids
- Let us know when the site is closed or quiet
- Name a contact who can let us in at the agreed time
Getting a quote
Quotes are quick. Call or email with a few details and you will normally have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.
Advice
When to call us in Chaulden
Any kitchen that cooks for long hours works its fan hard, in Chaulden or anywhere else. Belts on a belt-driven fan stretch and wear, so the fan squeals or turns more slowly.
Keep an eye out for any of the following:
- A belt-driven fan that squeals
- An extract fan that rattles or knocks
- A whining or grinding extract motor
- A failed fan that needs a replacement
If you manage a school such as Chaulden Junior School and the kitchen fan is getting louder, the next break is the time to deal with it.
Before booking anyone

What extract fan repair looks like in Chaulden
The FSA’s food hygiene register shows about 54 restaurants, cafés and canteens and about 37 sandwich bars and takeaways within roughly a mile and a half of the centre of Chaulden. For any of them with a canopy, the extract fan is what keeps the kitchen usable. Chaulden is about 25 miles from central London, well within the area we cover across London and the South East. We work evenings, overnight and at weekends, so the visit fits around the site. It’s Dacorum council that sends environmental health officers to food businesses in Chaulden. Ventilation is part of food hygiene law, which expects it to be suitable and sufficient. A kitchen without a working fan has a problem to fix quickly.
A fan that rarely runs, like one in a hall kitchen near St Stephen or elsewhere in Chaulden, can seize between uses. For a takeaway near Hemel Hempstead station, a fan that fails on a busy evening means turning customers away, and our emergency line runs 24/7.
Chaulden is about 2 miles west of Hemel Hempstead, in Hertfordshire.

We also work in Milton Keynes, around 23 miles away.

If you look after several sites, we can schedule visits across all of them on one quote. Each site gets its own report and photos, so records stay tidy.
In-house cleaning or a specialist?
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.
Looking after it afterwards
Good habits slow the build-up between visits. Our tips:
- Save our number for the 24/7 emergency line
- Keep the grease filters clean and fitted
- Note when the fan trips or cuts out
- Do not turn the fan down to hide a noise
If the fan had grease on it, the rest of the system almost certainly does too. A full TR19® clean deals with the canopy, ductwork and fan together and you get a TR19 certificate and photo report afterwards.
Noise is usually the first sign of a fan problem. Booking a check at this stage keeps it a planned job rather than an emergency during service.
