Extractor fan repair in Hunton Bridge

- A knocking noise from the extract fan
- A fan running too slowly to clear the kitchen
- A motor that trips out or overheats
Staff cleaning versus specialist work
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
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.
Extract fan repair in Hunton Bridge
Across Hunton Bridge, we deal with fan faults of every kind, 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. The work covers kitchen extract fans, bearings and roof and wall fans, and the jobs we see most are a fan that whines, hums or grinds and a knocking noise from the extract fan.
Somewhere as small as Hunton Bridge, a kitchen extract fan might serve a pub, a school, a care home or a hall kitchen. A failed fan stops the kitchen, and our 24/7 emergency line covers rural addresses too.
Duct Doctor has been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

Part by part
Impellers and housings
The impeller does the work of moving air through the system. Grease on it throws it out of balance and cause vibration.
Belt-driven fans
In a belt-driven fan, the motor drives the impeller by belt. Worn belts squeal and slow the fan down, and pulleys and bearings need checking too.
Signs you need extract fan repair in Hunton Bridge
When filters clog and ducts fill with grease, the fan has to strain. An overworked motor overheats, trips out or eventually burns out.
Common reasons sites call us are:
- A whining or grinding extract motor
- A failed fan that needs a replacement
- A belt-driven fan that squeals
- A fan that keeps cutting out
For kitchens close to Kings Langley station, a fan that stops mid-service needs fixing fast, and our emergency line runs 24/7.

What else we do in Hunton Bridge
Keeping the system healthy
After the visit, a few habits help the work last:
- Get a noisy fan checked rather than slowed down
- Do not wait for a noisy fan to stop
- Clean or change filters on schedule
- Book regular TR19 cleaning, which includes the fan
Keep an ear on the fan after the repair. If anything changes, let us know, so it can be looked at before it grows.
Clogged filters make the fan strain. Keeping filters clean eases the strain and protects the motor.

Hunton Bridge: your questions answered
Can you come to Hunton Bridge after we close?
Yes. We work evenings, overnight and at weekends. That way a site in Hunton Bridge doesn’t have to lose a day’s trading. When you call us on 0345 646 2711, or send details by email, mention when the site is quiet.
Can you get to a site in Hunton Bridge?
Yes, Hunton Bridge is part of our area, however small the site. A survey first, from photos or a visit, means we arrive with the right kit.
What types of premises do you cover?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, plus food production and leisure sites.
What should go in our maintenance log?
Visit reports, certificates and your in-house cleaning logs. They’re what an insurer, fire officer or EHO may ask for, so keep them together and easy to find.
What happens to the waste?
We take it away at the end of the visit. While we work, it’s kept contained to keep the area clean.
What happens if you cannot reach some of it?
They’re marked on the report. In ductwork, new access panels are often the answer, and we can fit those.
What do you do to protect the area?
We cover floors and nearby surfaces with sheeting before any work starts, and waste is contained as we go. Before we leave, we tidy up and clean down.
What’s TR19?
A BESA specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not legislation, but it’s the standard people check against.
What we do, step by step
A visit follows the same order every time: protect the area, make the system safe, do the work, tidy up and hand over the paperwork. The visit itself takes an hour or two to diagnose, then longer if parts or a new fan are needed. Somewhere as small as Hunton Bridge, the date and timings are agreed with you well before the day.
- 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
- Let us know about parking and loading
- Let us know when the site is closed or quiet
- Let us know how we reach the system, including roofs, risers and plant rooms
Get a fixed 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 we can price many jobs without a visit.
