Extract fan repair for kitchens and businesses in Barnes Cray
Our engineers handle all sorts of fan faults in Barnes Cray, from rattling and humming to a fan that has stopped dead. We find the cause, give you a fixed price and fix it or fit a replacement when it’s beyond repair. Typical jobs include a failed fan that needs a replacement and a motor that trips out or overheats, across kitchen extract fans, belts and pulleys and bearings.
Kitchens around a smaller place like Barnes Cray often have fans fitted to a wall or roof years ago. When an older fan fails, replacing it can be the better answer, and we will explain the options.
The sign-off is always in writing: a dated report with photos of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

What affects the quote in Barnes Cray
You’ll get a fixed price before we start. It takes into account:
- Site rules, permits and inductions
- How easy every part is to reach
- The condition of the system
- The number of sites or systems
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we will explain each part.
What to send for a quote
You don’t need the technical terms. It helps if you can send:
- Any symptoms, from odd noises to smells or leaks
- The paperwork from the last visit, if you have it
- Close-ups of filters, grilles, hatches or access panels
- How we’d reach plant on a roof or in a plant room
Getting a quote does not take long. Send a few details and pictures, and we typically reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.
Barnes Cray: your questions answered
Can you work in Barnes Cray outside opening hours?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. When you give us a ring on 0345 646 2711 or use the quote form, mention when the site is quiet.
Who would carry out a food hygiene inspection at a kitchen in Barnes Cray?
Kitchens in Barnes Cray are inspected by Bexley council’s environmental health officers. An officer may ask how the kitchen is ventilated, so keep repair records with your maintenance file.
How do you keep the site clean during the work?
With sheeting and covers, before anything else happens. The work is kept contained and leave the area clean.
Will we have to shut during the visit?
Usually not. 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.
Is repair an option before replacing the whole fan?
We look at repairing it first. Where the motor has burnt out or the fan is worn out, replacing it can be the better answer, and we will explain why.
Does the report say when we need you again?
Yes. The recommended date is on the report. BESA’s minimum intervals for kitchen extracts range from 3-monthly for heavy use to 12-monthly for light use, while fire dampers are tested at least annually.
Are you fully insured?
Yes. Duct Doctor is fully insured, and the details are available on request.
Can you tell me the price of a fan repair?
The price depends on the diagnosis. After we’ve checked the fan, we give you a fixed price for whichever option you choose.
Different parts, different methods
Roof and wall-mounted fans
Fans outside are exposed to rain and condensation. Rust on fixings and housings is a frequent find.
Impellers and housings
A damaged or corroded impeller cannot simply be cleaned. It may need replacing, or the fan may need replacing as a whole.
When something else is needed
In fairness, there are a few things this work will not fix:
- An extract system that was undersized from the start
- Grease throughout the ductwork, which needs a full TR19 clean
- Problems with the electrical supply to the fan (an electrician’s job)
If you’re not sure, just give us a ring on 0345 646 2711 or email us and we’ll give you a straight answer before you book.

Aftercare tips
No system stays clean for ever, but care slows the build-up. A few tips:
- Clean or change filters on schedule
- Get a noisy fan checked rather than slowed down
- Keep the fan on a planned cleaning cycle
- Note when the fan trips or cuts out
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. Changing or cleaning them on time takes load off the motor and helps prevent overheating.

What we’re called out for in Barnes Cray
Fans everywhere, Barnes Cray included, live in a hard environment: hot, greasy, damp air for hours on end. Condensation can corrode parts, and age catches up with every fan in the end.
These are the problems we see most often:
- A dead fan motor
- Vibration spreading from the fan into the ducts
- Weak extraction and a smoky kitchen
- A worn or slipping fan belt
If you run a church or community hall kitchen, near Christ Church or elsewhere in Barnes Cray, an extract fan that rarely runs can seize or fail when it’s needed.

Around Barnes Cray, access is typically simpler than in a town centre, though gates and roof access are worth mentioning.
- We take details of the symptoms and book a time that suits the kitchen.
- On site, the fan is safely isolated.
- The fan and its controls are checked to pin down the fault.
- A fixed quote for the repair or replacement follows.
- The work is done and the fan is tested running.

In-house cleaning or a specialist?
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
