Longfield Hill extract fan repair
Extract fan repair for Longfield Hill and the surrounding area: diagnosis first, then a fixed quote, the work and a report with photos. Ask us for a fixed quote.
- A fan that whines, hums or grinds
- A dead fan motor
- An extract that vibrates through the ductwork
How the visit works
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so a kitchen or building can carry on as usual the next day. The visit itself takes a few hours on site, depending on the fault and the access to the fan. Photos of the system and how to reach it help us plan a visit to Longfield Hill.
- 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.
- You get a fixed price for putting it right.
- We fix the fault and run the fan to check it.
How to prepare
- Tell us the best time to work, such as after service or at a weekend
- Tell us where we can park and unload
- Plan for cooking equipment or plant to be off before we arrive
Ask for a quote
The quickest way to a quote is to send photos: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.

How we handle extract fan repair in Longfield Hill
We treat a failing fan much like a patient: we hear the symptoms, find the cause and put it right. The aim is steady, quiet extraction and a clear explanation of what was done. If you have an overheating extract motor and a fan shaking on its mountings, we can put it right, from fan housings, bearings and fan motors onwards.
In a small place like Longfield Hill, fans are often on an outside wall or roof, open to wind and rain. That, with the grease, is hard on motors and bearings.
It’s worth checking any contractor’s accreditations. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

What your team can do, and what needs us
Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.
Why act early in Longfield Hill
In kitchens with an interlocked gas supply, no extract can mean no cooking. Even without an interlock, cooking without extraction is not sensible and fixing the fan early avoids a forced shutdown. It’s worth booking a check, because nobody sees inside a duct day to day.
Several systems or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at, and you’ll get one fixed quote.
Why choose Duct Doctor in Longfield Hill
- Each visit written up, with pictures
- Full insurance on every job
- Survey first, then a fixed quote
- A fixed price before any work starts
Between visits
Think of this as the after-treatment advice, in brief:
- Never run the extract with filters missing
- Tell us about a new rattle or whine right away
- Make sure the fan is cleaned with the rest of the system
- Make sure the isolator and controls are easy to reach
Where parts need ordering, we explain what that means for the kitchen until we return. The fan is completed on a return visit at a time that suits your service.
Clogged filters make the fan strain. Keeping filters clean eases the strain and helps prevent overheating.
Different parts, different methods
Roof and wall-mounted fans
Noise from an outside fan can carry beyond the kitchen. It’s often down to loose mounts or worn bearings.
Direct-drive fans
Direct-drive fans have the impeller mounted straight on the motor. With no belts to wear, we look at the motor, bearings and impeller.
Common questions in Longfield Hill
Do you work at weekends in Longfield Hill?
Yes, nights and weekends are routine for us. The work in Longfield Hill can fit around your hours. Just give us a ring on 0345 646 2711, or send details by email with your opening times and we will plan around them.
Is there an emergency callout for extract fans in Longfield Hill?
Longfield Hill is covered, and our emergency callout runs 24/7. Phone 0345 646 2711 and we’ll talk through the fault and access. A photo of the fan’s rating plate helps.
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.
Do I get a report after the visit?
Yes, always. It’s a dated, written report with photos, and TR19® Grease cleans come with a certificate through the BESCA VHE portal. Keep it in your maintenance log.
What do you do with what you remove?
We take it away when we go. During the work, it’s contained to keep the area clean.
Is TR19 a legal requirement?
No. TR19® is BESA’s specification, not legislation. The law is the Regulatory Reform (Fire Safety) Order 2005, which makes the responsible person assess and reduce fire risk, and TR19® is the benchmark for showing that grease in the extract is under control.
How much does an extract fan repair cost?
The cost depends on what’s wrong and how easy the fan is to reach. We diagnose first and give you a fixed price so there are no surprises.
What should go in our maintenance log?
Every certificate and report from each visit, kept together in your maintenance log, along with your own cleaning log. BESA advises that certificates record the date, location and technician.
When a fan fails in Longfield Hill
There are about 6 cafés, restaurants and staff canteens and about 4 sandwich bars and takeaways within about 1.5 miles of central Longfield Hill, according to the Food Standards Agency’s register. For any of them with a canopy, the extract fan is what keeps the kitchen usable. Food hygiene inspections in Longfield Hill are the job of Dartford council’s environmental health team. Under food hygiene rules, a kitchen needs suitable and sufficient ventilation. So a failed fan is worth fixing before the next service, not the next month. We cover Longfield Hill, about 20 miles from central London, as part of our work across London and the South East. 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 Istead Rise Primary School, fix a failing fan before term starts. If you run a church or community hall kitchen, near Church of St Mildred or elsewhere in Longfield Hill, an extract fan that rarely runs can seize or fail when it’s needed.

How we price extract fan repair
The diagnosis comes before the price. We look at:
- Parking and loading at the site
- Whether we need access equipment or extra panels
- Whether it’s a one-off visit or part of a schedule
- The condition of the system
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, which can make the next visit longer. If you’re unsure, call 0345 646 2711, or send details by email and we will give you an honest view and a fixed quote.
What we need to know
A few details help us quote accurately. With your enquiry, please include:
- The times we could work without disrupting the site
- Photos showing the whole system and its surroundings
- Your last certificate, test record or report
- Any access panels or hatches you can see
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, you get a fixed price before any work starts.
Multi-site and managed buildings
From a single site to a large estate, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with photos.
Managing agents often deal with us directly. Send the address, what’s needed and how access works and we’ll come back with a fixed quote.
