About our extract fan cleaning in Weston
Duct Doctor has been cleaning kitchen extract fans since 2009. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, with CHAS, SafeContractor and ISO 9001 and full insurance. If you have a heavily greased fan housing and a fan that no longer moves enough air, we can help, from axial fans, roof-mounted fans and centrifugal fans onwards.
For a kitchen in or near Weston, the visit is planned around opening hours and the journey, and the clean itself is the same full TR19® job as in any town: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.
The sign-off is always in writing: a written report, dated and illustrated with pictures, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

Weston kitchens: local notes
Weston sits within the area of Hertfordshire Fire and Rescue Service. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel. At about 32 miles from central London, Weston sits well inside the area we cover. We work evenings, overnight and at weekends, so the visit fits around the site.
A hall kitchen that only cooks for events, whether near Church of the Holy Trinity or elsewhere in Weston, still needs its extract cleaned, just less often. School kitchens, at schools like Weston Primary School for example, are normally cleaned in the holidays so no lunches are lost.
Weston is about 3 miles south-east of Letchworth, in Hertfordshire. We carry out extract fan cleaning for businesses, landlords and public buildings in Weston and the rest of Hertfordshire. Our Hertfordshire coverage runs to 381 places, Weston among them. We also work in Milton Keynes, about 26 miles from Weston.

Around Weston
Locally, jobs take us to businesses close to Red Lion Public House and The Knights Templar School, among other places. The nearest railway station is Baldock station, about 2.7 miles north. A little further out are Clothall Castle (1.1 miles north-east) and Lister Hospital (2.9 miles south-west). Green spaces nearby include Pryor's Wood.
Keeping the system healthy
Good habits slow the build-up between visits. A few tips:
- Note any drop in extraction at the canopy
- Make sure the fan is included each time
- Keep access to the fan clear
- File the fan’s report with your other records
Keep the report with the maintenance log and fire risk assessment. It shows the fan’s condition at the time of the clean, which helps if anything changes later.
The fan stays cleaner when less grease gets past the canopy. Keep the grease filters clean, fitted and in place, and replace any that are damaged.
What happens on the day
The first job on site is protection: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. The work on site takes a few hours where there are several fans or heavy deposits, and we clear up before we go. A few pictures of the system help us make the most of a visit to a place like Weston.
- The fan is found and its type, access and isolation checked.
- We isolate the power before opening the housing.
- Grease is scraped off the impeller blades and casing.
- The fan is degreased, taking care around the motor.
- It’s closed up, run, checked and photographed for the report.
How to prepare
- Allow time for equipment near the work to be turned off and cool down
- Tell us about site rules, permits or sign-in
- Arrange a key holder or contact on site

Advice
Fixed quotes for extract fan cleaning in Weston
Sites vary more than people expect. The main factors:
- What state the system is in
- How big the system is
- Whether several sites go on one quote
- Where the site is and how we reach it
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.
What to send for a quote
When you call or email, these details help:
- The times we could work without disrupting the site
- Detail shots of panels, filters and grilles
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The postcode and the type of business
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. Add the site type and your opening hours, and many jobs can be priced from that alone.
What extract fan cleaning can’t fix
To be straight with you, there are a few things this work will not fix:
- A motor that has burnt out
- Electrical faults in the fan’s supply or controls (an electrician’s job)
- A dirty duct upstream of the fan
If you’re not sure, just call 0345 646 2711 or use the quote form and we will give you a straight answer before you book.
Parts of the system we cover
- In-line fans
- Axial fans
- Discharge points
- Fan housings
- Centrifugal fans
- Roof-mounted fans
How the job changes from site to site
Inline duct fans
Inline fans can be in tight spaces, so we plan how to reach and clean them. If it cannot be reached fully, the report says so.
Kitchens with long cooking hours
Kitchens that cook 12 to 16 hours a day put the most grease through their fans. Under BESA guidance, heavy use means cleaning at least every 3 months, fan included.
Weston: your questions answered
Can you get to a site in Weston?
Yes. Weston is within the area we cover across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Who inspects food businesses in Weston?
In Weston, it’s North Hertfordshire council that carries out food hygiene inspections. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Is it safe to clean the fan while the kitchen is open?
We isolate the fan, so the kitchen can’t cook while we work. That’s why fan cleans are done out of hours, and the kitchen is ready when we leave.
What makes a kitchen extract fan vibrate?
An unbalanced impeller, normally from uneven grease, is a common cause. After cleaning, we will tell you if wear or damage is also involved.
Do you offer emergency callouts?
Yes. There’s a 24/7 emergency line for anything that can’t wait until a planned visit. Call us any time and explain what’s happened.
How long will it take to clean the fan?
That depends on the fan’s size, its position and how much grease there is. Typically it takes a couple of hours per fan, depending on its size and the build-up.
How do you protect the area?
Protection goes down first: floor sheeting and covers over nearby surfaces and equipment. We tidy up and take our waste away before we leave.
Can you look after several sites?
Yes. Tell us the addresses and what each needs and you’ll get one fixed quote.
When to call us in Weston
The fan sits at the end of the grease’s journey. The grease that is left lands on the blades and the casing, and the spinning blades fling it onto the walls of the housing.
If you notice any of these, it’s worth a diagnosis:
- Fat spreading onto the roof or wall by the fan
- A fan left out of previous cleans
- A smell of hot grease from the extract
- A motor area thick with grease
If you run catering at a healthcare site, such as a hospital like Lister Hospital about 2.9 miles south-west, the extract may need cleaning more often than a part-time kitchen.
What to look for in a quote
- What records you’ll receive afterwards
- Whether the work can be done while the site is closed
- How they set the interval to the next visit
- Proof of accreditation you can verify
For landlords and multi-site operators
For anyone managing more than one site, we can schedule visits across all of them on one quote. Every building has its own written report, so each one has its own record.
Multi-site operators often want one contractor and one number. We work across London and the South East, so a run of sites can go into one programme and kept on a regular cycle.
