Extract fan repair in Dunton, done properly
Grease is hard on extract fans. Deposits on the impeller throw it out of balance and the vibration wears out bearings and fixings. That’s 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. The work covers fan motors, bearings and roof and wall fans, and people most often call us about a fan worn beyond sensible repair and a worn or slipping fan belt.
For a fan repair in or near Dunton, the more you tell us about the fan, the better the first visit: pictures of the fan, its rating plate and how to reach it all help.
The paperwork matters as much as the work. You get a written report with pictures after each visit, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

What we are called out for in Dunton
In Dunton, as anywhere, long cooking days mean long hours for the fan. On belt-driven fans, belts stretch, crack and start to slip and a slipping belt means slower fan speed and weaker extraction.
What we are most often called out for:
- A knocking noise from the extract fan
- An old fan that needs replacing
- A whining or grinding extract motor
- A worn or slipping fan belt
If a fan fails in Dunton at night or at a weekend, our emergency line is open.

Different parts, different methods
Roof and wall-mounted fans
Fans are often mounted on roofs or external walls. How easy the fan is to reach shapes the job, so we ask about it early.
Impellers and housings
The fan housing collects grease too. Both are inspected, and cleaning can form part of the repair.
Leave it or put it right?
A struggling motor runs hotter and works harder. Every hour of strain takes its toll, and when it finally fails, it may take other parts with it. Early attention keeps the cost and disruption down. With notice, the visit to Dunton can be fitted around your bookings and events.
The cost depends on the size of the system, the condition it’s in and how easy it is to reach. You get a fixed price before we start, so there are no surprises.

When something else is needed
Not every problem is solved by extract fan repair, and we’d rather say so up front. It doesn’t solve:
- Cooking smells reaching neighbours, which may need odour control
- Problems with the electrical supply to the fan (an electrician’s job)
- Grease throughout the ductwork, which needs a full TR19 clean
If you are not sure, just ring 0345 646 2711 or email us and we will give you a straight answer.

Common questions in Dunton
Can you come to Dunton after we close?
Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. Tell us your opening hours when you ask for a quote.
Do you cover smaller places like Dunton?
Yes, Dunton is part of our area, however small the site. Just mention lanes, gates or anything else about the site when you book.
Which kinds of sites do you work on?
Commercial premises of every kind: kitchens, offices, schools, healthcare, retail, leisure and food production. We fit the work around how the site operates.
Will we have to shut during the visit?
Not usually. Booking the work out of hours means the site can carry on as normal. Larger jobs can be phased over several visits to keep things running.
How far ahead should we book?
Book as early as you can for planned work, especially if the next clean or test is due soon. Emergencies are different, because our line is open 24/7.
Does a fan repair include cleaning the ductwork?
A repair deals with the fan, not the grease in the rest of the system. If there’s grease on the fan, a full TR19® clean is worth booking, and we can arrange both.
How do you protect the area?
With sheeting and covers, before anything else happens. The work is kept contained and clean down when we finish.
What is TR19?
TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Between visits
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Don’t cook with gaps in the filter bank
- Keep access to the fan controls unobstructed
- Keep the emergency number where staff can see it
- Keep the grease filters clean and fitted
Your kitchen can get back to normal as soon as the fan is running. We clear up after ourselves and talk you through what we found.
Regular TR19 cleaning includes the extract fan. Keeping grease off the impeller is one of the simplest ways to protect it and that means less wear.
What we do, step by step
Every visit runs to the same pattern: sheeting and protection first, make the system safe, carry out the extract fan repair, tidy up and hand over the paperwork. The visit itself takes a few hours on site, depending on the fault and the access to the fan. For a village or hamlet like Dunton, tell us about narrow lanes, gates and parking when you book.
- We ask what the fan is doing, from noise and vibration to a full stop.
- 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.
- You get our diagnosis and a fixed quote to repair or replace.
- We fix or replace the fan, then test it running before we leave.
Before we arrive
- Let us know when the site is closed or quiet
- Name a contact who can let us in at the agreed time
- Make sure equipment near the work can be switched off and left to cool
How to get a quote
Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.

How we price extract fan repair
We do not publish a price list, because no two systems are the same. What we look at:
- Where the site is and how we reach it
- The condition of the system
- Whether it’s a one-off visit or part of a schedule
- When the work can happen, such as evenings, overnight or weekends
One small site or a whole estate, we price it on the same basis: what needs doing, how we get to it and when. You’ll have a fixed price before work begins.
Helping us quote
Before you ask for a quote, gather:
- The postcode and the type of business
- Detail shots of panels, filters and grilles
- Problems your staff have spotted
- Wide photos of the system and the area around it
To help us quote: the address, the type of site and when it’s open, pictures of the system and any previous report or certificate. Then call us on 0345 646 2711, or send details by email.
