Extract fan repair for kitchens and businesses in Chaldon
Before anything is ordered, we diagnose. We look at the motor, the belts or direct drive, the impeller and the mountings and the speed control too. After that, you get a fixed price for what’s needed. If you’re dealing with an extract fan that has stopped working and a failed fan that needs a replacement, we can put it right.
Somewhere as small as Chaldon, a kitchen extract fan might serve a pub, a school, a care home or a hall kitchen. A failed fan stops the kitchen, and emergency callout is available 24/7, villages included.
The paperwork matters as much as the work. You get a written report with photos 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 ready for an insurer, fire officer or EHO.

Why act early in Chaldon
A fan that’s running slowly isn’t clearing the kitchen properly. The kitchen becomes an uncomfortable place to work and grease has more chance to settle on surfaces and in the duct. It’s simpler to plan the work at Chaldon now than to arrange it in a hurry later.
What you pay reflects the actual work. That is why every job is surveyed first, and why the quote is fixed before any work starts.

When something else is needed
We will always give you a straight diagnosis, so here’s what this work can’t put right:
- Odour complaints that need filtration rather than a fan repair
- Ductwork designed too small for the kitchen’s cooking
- Problems with the electrical supply to the fan (an electrician’s job)
If in doubt, ring 0345 646 2711, or send details by email and we will say what we think.

Chaldon questions
Is there an emergency callout for extract fans in Chaldon?
We run a 24/7 emergency line for failed extract fans, and Chaldon is part of our area. Use 0345 646 2711, our emergency number, at any time. Let us know whether the fan is silent, noisy or tripping the power.
Who inspects food businesses in Chaldon?
The local authority for Chaldon is Tandridge council, and its environmental health team does the inspecting. An officer may ask how the kitchen is ventilated, so keep repair records with your maintenance file.
Do I get a report after the visit?
Yes. It’s the record insurers and inspectors ask to see: a dated report with photos, listing the work and any areas we couldn’t reach.
What makes a kitchen extract fan rattle or whine?
Grease on the blades throws the fan out of balance and that is one of the most common reasons. Worn bearings, belts and loose mounts are others.
Should the fan be cleaned as well as repaired?
Doing both together is often sensible. A TR19 clean covers the canopy, plenum, ductwork and fan, with a certificate and photo report.
Are you insured?
Yes, fully. CHAS and SafeContractor accreditation sit alongside it for clients who vet their contractors.
Can one contract cover all our sites?
Yes. One number covers all your sites in our area, with visits on a regular schedule.
What does TR19 mean?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
What extract fan repair looks like in Chaldon
The FSA’s food hygiene register shows about 41 restaurants, cafés and works canteens and about 21 takeaways and sandwich shops within 1.5 miles or so of the middle of Chaldon. For any of them with a canopy, the extract fan is what keeps the kitchen usable. Kitchens in Chaldon get their food hygiene inspections from Tandridge council. Food hygiene rules expect food premises to have suitable and sufficient ventilation. That makes a fan repair urgent rather than something to put off. Chaldon, about 15 miles from central London, is within our usual area. The visit is fixed around your opening hours, not ours.
Occasional-use kitchens, such as a hall kitchen near Church of St Peter and St Paul or elsewhere in Chaldon, are where a stiff or seized fan can turn up.

Keeping the system healthy
Think of this as the after-treatment advice, short and simple:
- Keep the emergency number where staff can see it
- Keep access to the fan controls unobstructed
- Get a noisy fan checked rather than slowed down
- Clean or change filters on schedule
Your kitchen can get back to normal as soon as the fan is running. We clear up after ourselves and explain anything you need to know.
Clogged filters make the fan strain. Keeping filters clean eases the strain and protects the motor.
Staff cleaning versus specialist work
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
When to call us in Chaldon
Fans everywhere, Chaldon included, live in a hard environment: hot, greasy, damp air for hours on end. Condensation can corrode parts and eventually any fan simply wears out.
Signs it’s time to call us include:
- A fan that will not start at all
- Weak extraction and a smoky kitchen
- An overheating extract motor
- A fan rattling in its housing
School kitchens cannot easily serve lunch without extraction, so if you look after one at a school like St Peter and St Paul CofE Infant School, fix a failing fan before term starts.

Multi-site and managed buildings
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.
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements and we will come back with a fixed quote.
The process
Your staff do not need to do much on the day. Someone lets us in at the agreed time and shows us where everything is, and the rest is down to us. Afterwards, the area is left tidy and the written report follows. The timing of a visit to Chaldon is set by you, and the travel is our side of the planning.
- We start with the symptoms, such as rattling, humming, slow running or a fan that won’t start.
- Power to the fan is isolated before we open the housing.
- We check the motor, bearings, drive, impeller and mountings.
- You get our diagnosis and a fixed quote to repair or replace.
- Once the work is done, we run the fan and check it’s steady and quiet.
Preparing for the visit
- Clear loose items from the work area
- Arrange a key holder or contact on site
- Allow time for equipment near the work to be turned off and cool down
Getting a quote
Quoting starts with a diagnosis, either from photos and details you send or from a site visit. Then we send a fixed price, before work begins.
