How we handle extract fan repair in Dorking
Working on a fan in Dorking means switching the extract off first, 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. The work covers roof and wall fans, fan motors and bearings, and people most often call us about an extract that vibrates through the ductwork and a failed fan that needs a replacement.
For a pub, café or takeaway in a town like Dorking, no extract fan means no cooking. Our 24/7 emergency callout is there for exactly that.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

Landlords, agents and facilities managers
Running several sites is easier with one contractor. We work across London and the South East, so a run of sites can go into one programme and kept to a regular schedule.
For anyone managing more than one site, we can schedule visits across all of them on one quote. Every building has its own written report, so records stay tidy.
FAQs for Dorking
Can you come to Dorking after we close?
Yes, out-of-hours work is a big part of what we do. It means the site in Dorking keeps running as normal. When you ring 0345 646 2711 or use the quote form, mention when the site is quiet.
Is there an emergency callout for extract fans in Dorking?
Day or night, a failed fan in Dorking can be reported on our emergency line. Ring 0345 646 2711 at any hour and describe the fault. Let us know whether the fan is silent, noisy or tripping the power.
What types of premises do you cover?
Commercial premises of every kind: kitchens, offices, schools, healthcare, retail, leisure and food production. We fit the work around how the site operates.
What is TR19?
BESA’s ventilation hygiene specification in two main parts: 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.
What if parts of the system can’t be reached?
We never leave them off the paperwork. You’ll know exactly which parts weren’t reached and why, along with a quote to put access in.
Where does the waste go?
We contain it and take it with us. Grease, debris and waste water are collected as the work goes on, so it doesn’t spread.
Is there a survey before the work?
Yes. We always survey first, from your photos and details, or with a visit where necessary. A fixed quote follows.
Are you fully insured?
Yes. Duct Doctor is fully insured, and we can share the details when you need them.
The process
We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool before work begins, and the area around the work is covered and protected. The work itself takes a few hours on site, depending on the fault and the access to the fan. Parking in a town like Dorking is usually straightforward, so the main questions are access and timing.
- First, you tell us the symptoms: noise, shaking, weak extraction or no power.
- Power to the fan is isolated before we open the housing.
- The impeller, bearings, belts or drive, motor and mounts are all inspected.
- You hear what’s wrong and what it will cost, with a fixed quote, before we go ahead.
- Once the work is done, we run the fan and check it’s steady and quiet.
Getting ready for the visit
- Find the previous report, if there is one
- Tell us about site rules, permits or sign-in
- Name a contact who can let us in at the agreed time
Getting a quote
Some systems can be priced from pictures; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.
Related advice
What staff can safely do
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
Staff cleaning and specialist work aren’t the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.
Aftercare tips
No system stays clean for ever, but care slows the build-up. A few tips:
- Keep the emergency number where staff can see it
- Make sure every filter is in place and clean
- Don’t wait for a noisy fan to stop
- Make sure the isolator and controls are easy to reach
Before we leave, the fan is run and checked. We explain the fault and the fix along with anything else that needs watching.
When filters block, the fan works harder. Changing or cleaning them on time takes load off the motor and helps prevent overheating.
How we price extract fan repair
We don’t publish a price list, because no two systems are the same. The quote depends on:
- How many systems or sites are involved
- What state the system is in
- How big the system is
- Working hours and out-of-hours timing
Putting the work off seldom saves money. Problems in a system tend to grow, which can make the next visit longer. If you are unsure, ring 0345 646 2711, or email photos for straight advice and a fixed quote.
Helping us quote
Photos let us diagnose from a distance. Try to include:
- Wide photos of the system and the area around it
- Detail shots of panels, filters and grilles
- Your opening hours and when the area is out of use
- How we’d reach plant on a roof or in a plant room
The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.

What extract fan repair looks like in Dorking
There are about 59 restaurants, cafés and works canteens and about 10 takeaways within 1.5 miles or so of the middle of Dorking, according to the Food Standards Agency’s register. Wherever they cook under a canopy, a failed extract fan stops the kitchen. It’s Mole Valley council that sends environmental health officers to food businesses in Dorking. A kitchen with no working extract can fall short of the suitable and sufficient ventilation food hygiene rules expect. So a failed fan is worth fixing before the next service, not the next month. At about 21 miles from central London, Dorking sits well inside the area we cover. The visit is fixed around your opening hours, not ours.
School kitchens can’t easily serve lunch without extraction, so if you look after one at a school like St Paul's CofE (Aided) Primary School, fix a failing fan before term starts. For kitchens close to Dorking Deepdene station, a fan that stops mid-service needs fixing fast, and our emergency line runs 24/7.

When to call us in Dorking
Over the years, mountings loosen and rubber mounts break down. The fan’s movement then travels into the ductwork and structure, which is where knocking and rattling often come from.
Keep an eye out for any of the following:
- Weak extraction and a smoky kitchen
- A humming noise from the fan motor
- An extract fan that rattles or knocks
- Vibration spreading from the fan into the ducts
Occasional-use kitchens, such as a hall kitchen near Church of St Paul or elsewhere in Dorking, are where a stiff or seized fan can turn up.

What extract fan repair cannot fix
Not every problem is solved by extract fan repair, and we’d rather say so up front. It does not solve:
- Grease build-up in the rest of the extract system
- A system that needs redesigning rather than repairing
- Problems with the electrical supply to the fan (an electrician’s job)
If you’re not sure, just call 0345 646 2711, or send details by email and we will give you a straight answer before you book.
