Leverstock Green extract fan cleaning
Our technicians work in Leverstock Green on extract fan cleaning. Out-of-hours visits, a fixed quote and a written report with photos as standard.
- A fan left out of previous cleans
- A noisy fan that has got louder over time
- A motor area thick with grease
Staff cleaning versus specialist work
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That’s our job.
How we handle extract fan cleaning in Leverstock Green
Cleaning removes grease, not wear. If we find worn bearings, a struggling motor or damage to the impeller, we will tell you, and we also repair and replace extract fans. You get an honest view of the fan’s condition. If you have thick grease on the impeller and casing and grease escaping from the fan outlet, we can help.
Size does not change the work: a kitchen in a place like Leverstock Green gets the whole system cleaned, canopy to discharge. We plan the visit around your hours, with the journey sorted in advance.
The sign-off is always in writing: a written report, dated and illustrated with photos, 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.

Between visits
A little care between visits keeps the system in better shape. Our advice:
- Don’t turn the fan off mid-service
- Check filters are seated before cooking
- Leave a clear route to the fan
- Watch for grease marks around the outlet
A full system clean includes a TR19 certificate from the BESCA Vent Hygiene Elite portal. If only the fan is cleaned, the photo report says so.
Run the fan throughout cooking. Grease settles faster when the air stops moving, so keeping it running helps keep it clean.
What extract fan cleaning looks like in Leverstock Green
Food Standards Agency records list about 50 restaurants, cafés and works canteens and about 24 takeaways within roughly a mile and a half of the centre of Leverstock Green. Grease builds up on fan blades and housings in kitchens like these, unbalancing the impeller. Hertfordshire Fire and Rescue Service covers Leverstock Green. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. In Leverstock Green, food businesses are inspected by environmental health officers from Dacorum council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A dated certificate in the maintenance file answers the question before it’s asked.
If you run a church or community hall kitchen, near Church of Holy Trinity or elsewhere in Leverstock Green, its extract still collects grease from every lunch and event. If you run catering at a healthcare site, such as a hospital like Hemel Hempstead Hospital about 1.6 miles west, the extract may need cleaning more often than a part-time kitchen.

How it works
When we arrive, we check the system against the survey or the photos you sent. Anything unexpected is raised with you before we go further. From there, it takes an hour or two for most single fans. Around Leverstock Green, access is typically simpler than in a town centre, though gates and roof access are worth mentioning.
- First we locate the fan and agree how it’s safely isolated.
- Power to the fan is isolated before anyone touches it.
- The impeller and the housing around it are scraped clean.
- The fan and its surrounds are degreased, keeping clear of the motor’s electrics.
- We reassemble, run the fan and photograph the result.
Preparing for the visit
- Agree a time when the area can be out of use
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Mention any sign-in, permit or induction we need

Advice
What happens if it’s left?
Vibration from an unbalanced impeller doesn’t stay small. It wears bearings and mounts and can lead to a breakdown, which may leave the kitchen without extraction. A planned clean beats an emergency. A planned visit to Leverstock Green fits your hours; an emergency doesn’t.
When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account, and the price is fixed before work begins.

Leverstock Green questions
Can the work in Leverstock Green be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. It means the site in Leverstock Green keeps running as normal. Just call 0345 646 2711 or use the quote form with your opening times and we’ll plan around them.
Which fire service covers Leverstock Green?
That’s Hertfordshire Fire and Rescue Service. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Is the fan isolated during cleaning?
We always isolate the fan first, so it can’t start while we work. That means the extract is off, so we clean while the kitchen is closed.
Does a TR19 kitchen extract clean cover the fan?
Yes. TR19® Grease covers the whole system, fan included. It’s isolated, opened and cleaned along with the canopy, plenum, filters, ducts and discharge.
Are you fully insured?
Yes. Duct Doctor is fully insured, and the details are available on request.
How long is a fan clean?
Allow an hour or two for most single fans. We’ll confirm the time when we quote.
What accreditations do you have?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.
What happens if you cannot reach some of it?
We record them on the report, with a note of where it is, and we tell you what would make it reachable, such as extra access panels in ductwork.
What the work involves, part by part
Impellers and blades
While the impeller is clean, we can see its condition: chips, distortion or wear. We note any concerns.
Fan housings and motors
Some fans use a belt drive. We clean around them and note any wear for your records.

Fixed quotes for extract fan cleaning in Leverstock Green
A fixed price needs a few facts first. We look at:
- Access, including roofs, risers and ceiling voids
- The scale of the work
- How many systems or sites are involved
- A single visit or a regular plan
One small site or a whole estate, we price it on the same basis: what needs doing, how we get to it and when. You will have a fixed price before work begins.
What to send for a quote
Photos let us diagnose from a distance. Try to include:
- Your last certificate, test record or report
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Close-ups of filters, grilles, hatches or access panels
- When the site is open and when it’s quiet
The quickest way to a quote is to send pictures: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
Signs you need extract fan cleaning in Leverstock Green
The cooler the air, the more grease drops out, and a fan out on a roof or wall often sits where the air is coolest. So grease often settles heavily there.
Common reasons sites call us are:
- Grease around the motor and its mounts
- Grease stains around the discharge
- A fan that has never been cleaned
- Thick grease on the impeller and casing
Bursars and site managers at schools such as Leverstock Green Church of England Primary School tend to book extract cleaning for when the kitchen is empty.
