Extract fan cleaning in Coleman Green
Duct Doctor has been cleaning kitchen extract fans since 2009. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, with CHAS, SafeContractor and ISO 9001 and full insurance. The work covers fan housings, in-line fans and centrifugal fans, and people most often call us about a motor area thick with grease and an extract fan with no cleaning record.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, where grease settles in the flat sections. Access, parking and timings are agreed before the day.
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. Any parts we couldn’t reach are recorded on it too.

Your questions about extract fan cleaning in Coleman Green
Which fire service covers Coleman Green?
Coleman Green is in the area of Hertfordshire Fire and Rescue Service. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Do you work in villages like Coleman Green?
Yes, Coleman Green is part of our area, however small the site. Photos of the system and directions to the site help us plan the visit.
What if the fan needs more than a clean?
Fan repair and replacement is part of what we do. If we find wear or damage, we’ll explain it and give you a fixed quote.
Will I get pictures of the cleaned fan?
A photo report, including the fan’s condition and the next clean date. File it with your other extract records.
Does a TR19 kitchen extract clean cover the fan?
Yes, a full TR19 clean includes the fan. If a fan cannot be reached, the report says so, so the record is accurate.
Why is my extract fan noisy?
Build-up on the impeller is a frequent reason, since uneven grease makes it run out of balance. Worn bearings and motor problems are others, which our report will flag.
Do we need to close while you work?
Not typically. The area we are working in has to be out of use while we’re there, so the visit goes in a quiet slot.
Do you work with multi-site operators?
Yes. We work across South East England and London, so sites at different addresses can be planned together on one programme. Every site has its own report.
What extract fan cleaning looks like in Coleman Green
The FSA’s data shows about 4 pubs and bars registered within roughly a mile and a half of the centre of Coleman Green. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. The fire and rescue service for Coleman Green is 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. Kitchens in Coleman Green get their food hygiene inspections from St Albans City council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Keeping each certificate and photo report on file helps show the extract is looked after.
School kitchens, at schools like Beech Hyde Primary School and Nursery for example, are normally cleaned in the holidays so no lunches are lost. Shaw's Corner, about 2.5 miles north, is one of the historic houses near Coleman Green; if you run event catering at a venue like that, cleans can be booked between functions. If you run catering at a healthcare site, such as a hospital like Hill End Hospital about 3.6 miles south, the extract may need cleaning more often than a part-time kitchen.

What the work involves, part by part
Roof-mounted fans
Roof fans also discharge grease onto the roof around them and we check the area around the outlet. We note any grease around the fan.
Fan housings and motors
Belt-driven fans have a drive belt and pulleys that can collect grease. Belts and pulleys are checked and cleaned where safe for your records.

What else we do in Coleman Green
The process
There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Afterwards, the area is left tidy and the written report follows. If you can send pictures, we can arrive in Coleman Green knowing what to expect.
- We locate the fan and plan how to reach and isolate it.
- It’s isolated so it can’t run while we work.
- We scrape the heavy grease from the blades and housing.
- The fan is degreased, taking care around the motor.
- We reassemble, run and photograph the fan.
Getting ready for the visit
- Mention any parking or loading restrictions
- Let us know about permits to work or site inductions
- Find the previous report, if there is one

Why deal with it now?
An unbalanced fan gets worse, not better. It wears bearings and mounts and can lead to a breakdown, which may leave the kitchen without extraction. A planned clean beats an emergency. Our emergency line runs 24/7, but a planned visit to Coleman Green is calmer for everyone.
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we’ll go through it with you.
Why book with us
- Evenings, overnight and weekends, plus 24/7 emergency callout
- Full insurance on every job
- Every job surveyed first
- One number for every site across the South East and London
Between visits
So the system stays in good health:
- Do not store items in front of the fan’s access point
- Report grease escaping from the fan
- Run the extract throughout cooking
- Check the report shows the fan was cleaned
If the fan needs more than a clean, we will say so plainly. We also repair and replace extract fans, so you have one point of contact.
Run the fan throughout cooking. Grease settles faster when the air stops moving, so keeping it running helps keep it clean.
What your team can do, and what needs us
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
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.
Honest limits
We will always give you a straight diagnosis, so here’s what this work can’t put right:
- Electrical faults in the fan’s supply or controls (an electrician’s job)
- Grease in the duct and canopy before the fan (those need a full TR19 clean)
- A fan that’s too small for the system (a design question)
If you are not sure, just phone us on 0345 646 2711, or send details by email and we’ll give you a straight answer before you book.
