Extract fan cleaning in Hudnall
Duct Doctor has been cleaning kitchen extract fans since 2009. As a BESCA Vent Hygiene Elite member, we clean to BESA TR19® Grease, and we are fully insured, with CHAS, SafeContractor and ISO 9001. Common call-outs are for vibration from an unbalanced impeller and a heavily greased fan housing, across axial fans, centrifugal fans and discharge points.
In a village or hamlet like Hudnall, the kitchens that need extract cleaning are usually a pub, a school, a care home or a hall kitchen, wherever there is one. Every one of them still needs its extract kept clear of grease.
Think of the report as the system’s health record: dated, with pictures, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

Managing agents and facilities teams in Hudnall
Keeping records across a portfolio is half the battle. Each visit ends with a dated report and pictures, so you can show an insurer or inspector what was done at each site.
From a single site to a large estate, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with pictures.
Signs you need extract fan cleaning in Hudnall
A greasy fan in Hudnall is fuel at the end of the duct. If grease in the duct catches, the fan and its housing can feed the fire and an overworked motor runs hotter.
If you notice any of these, it’s worth a diagnosis:
- A fan that has never been cleaned
- Grease around the motor and its mounts
- Fat spreading onto the roof or wall by the fan
- A heavily greased fan housing
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Hemel Hempstead Hospital is the nearest hospital to Hudnall, about 5.1 miles south-east.

How the visit works
The visit has three parts: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with pictures. The middle part takes longest, and that takes an hour or two for one fan, longer when it’s hard to reach. Seeing the system in pictures first means the trip to Hudnall can be planned properly.
- Diagnosis first: we look for grease, noise and vibration.
- Once isolated, we open the fan up.
- The impeller is cleaned blade by blade so it runs balanced.
- We clean the casing, the outlet and around the motor.
- We run the fan and note its condition in the photo report.
Getting ready for the visit
- Arrange a key holder or contact on site
- Clear the space around the work
- Make sure equipment near the work can be switched off and left to cool
Ask for 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 any work starts.
Related advice
Keeping the system healthy
Here’s the after-treatment advice, short and simple:
- Keep access to the fan clear
- Flag smoke lingering at the canopy
- Report rattles or humming early
- Book the fan into every full TR19 clean
Where the fan needs repair rather than cleaning, the report says so. Fan repair and replacement are services we offer too, so you have one point of contact.
Listen to the fan. New noise or vibration often means grease is building on the impeller, and catching it early keeps it a cleaning job.
What staff can safely do
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That’s our job.
What a clean will not put right
Extract fan cleaning can’t fix everything, and we’ll tell you before we start. It does not solve:
- A fan that was never right for the kitchen
- Wiring faults to the fan
- A motor that has burnt out
If in doubt, call us on 0345 646 2711 or email us and we will say what we think.

Common questions in Hudnall
Do you work overnight in Hudnall?
Yes, nights and weekends are routine for us. The site is handed back ready to open. Just ring 0345 646 2711, or send details by email with your opening times and we will plan around them.
Do you work in villages like Hudnall?
Yes, we work in villages as well as towns, and Hudnall is covered. Let us know about access, parking and anything unusual about getting there when you book.
Are you accredited?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We have been trading since 2009 and we are fully insured.
Will we have to shut during the visit?
Not usually. Out-of-hours visits keep the disruption down. Bigger sites can be done in stages to keep things running.
What is TR19?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t law, but it’s the benchmark.
Do you repair extract fans as well as clean them?
A clean will not mend wear. We repair and replace extract fans as well, with a fixed quote first.
What if parts of the system can’t be reached?
They’re marked on the report. In ductwork, new access panels are often the answer, and we can fit those.
What do you need from me for a quote?
Just the basics: where it is, what kind of site, when it’s open and the access. Photos and the last report help too. Then give us a ring on 0345 646 2711 or use the quote form.
Why deal with it now?
Cleaning the fan in Hudnall now is a short job: it takes a few hours where there are several fans or heavy deposits. Leaving it means more wear, more noise and a bigger clean later. Out of sight is the usual reason a rural system goes too long without attention.
Every site is different, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all make a difference.
Why us?
- We’re fully insured
- Evenings, overnight and weekends, plus 24/7 emergency callout
- One contact for all your sites in London and the South East
- Trading since 2009
