Extract fan cleaning in Chapmore End, done properly
If the ducts are the arteries, the fan is the heart. A heart under strain works harder for less. We clean it, run it and note anything that needs a closer look, before signing it off. The work covers in-line fans, centrifugal fans and axial fans, and common reasons people get in touch are a fan that no longer moves enough air and a noisy fan that has got louder over time.
Somewhere as small as Chapmore End, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Every one of them still needs its extract kept clear of grease.
We’ve been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.

Staff cleaning versus specialist work
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that’s where we come in.
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That’s our job.
Common questions in Chapmore End
Which environmental health team covers Chapmore End?
That is East Hertfordshire council, whose environmental health officers carry out food hygiene inspections in Chapmore End. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.
Can a school canteen extract in Chapmore End be done out of term time?
Yes, holiday work suits schools best. Around Chapmore End, the Food Standards Agency lists about 2 schools and colleges with registered kitchens within a mile and a half or so. Booking early in the term gives the best choice of holiday dates.
How long is a fan clean?
Allow a few hours where there are several fans or heavy deposits. Your quote will give an idea.
Do you work out of hours?
Yes, and that is how we prefer to work. The visit is timed for when the area isn’t in use, such as late evening, overnight or a weekend.
Will I get photos of the cleaned fan?
A photo report shows the fan before and after. Full system cleans come with a TR19 certificate as well.
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.
How often should the extract fan be cleaned?
It’s cleaned with the whole extract, from every 3 months for 12 to 16 hours of cooking a day to every 12 months for 2 to 6 hours. Grease readings and the fan’s condition can show it needs more.
Can you look after several sites?
Yes. Send the list of sites and the work at each and we will quote them together.
When it’s something else
Some problems need a different service or another trade:
- A dirty duct upstream of the fan
- A fan that was never right for the kitchen
- Wiring faults to the fan
If in doubt, call 0345 646 2711, or email photos and we will say what we think.

Kitchen extracts in Chapmore End
Food Standards Agency data counts about 5 restaurants, cafés and works canteens within roughly a mile and a half of the centre of Chapmore End. Any of those kitchens with a canopy relies on a fan that gathers grease as it runs. Hertfordshire Fire and Rescue Service covers Chapmore End. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract. It’s East Hertfordshire council that sends environmental health officers to food businesses in Chapmore End. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Keeping each certificate and photo report on file helps show the extract is looked after.
Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Aston Bury is about 4.9 miles north-west), access may need planning. If you run catering at a healthcare site, such as a hospital like Hertford County Hospital about 2.2 miles south, the extract may need cleaning more often than a part-time kitchen.
Chapmore End is about 2 miles north-west of Ware, in Hertfordshire. We carry out extract fan cleaning for businesses, landlords and public buildings in Chapmore End and the rest of Hertfordshire. Our Hertfordshire coverage runs to 381 places, and Chapmore End is one of them. We also work in London, about 23 miles from Chapmore End.

Nearby, we also carry out extract fan cleaning in Tonwell (1 mile north), Waterford (1 mile south-west), Bengeo (2 miles south), Thundridge (2 miles east) and Ware (2 miles south-east).

What’s near Chapmore End
Locally, jobs take us to businesses close to Chauncy School and Robin Hood & Little John pub and the streets around them. The closest station to Chapmore End is Hertford East station, about 1.9 miles south of the centre. A little further out are Hertford Railway Museum (1.5 miles south-west) and Hertford County Hospital (2.2 miles south). For a walk, there’s King's Meads.
For landlords and multi-site operators
Keeping records across a portfolio is half the battle. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.
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.
Looking after it afterwards
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Note any drop in extraction at the canopy
- Keep the grease filters clean and in place
- Keep each photo report with the maintenance log
- Check the report shows the fan was cleaned
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.
Do not run the kitchen with the extract off. Grease settles faster when the air stops moving, so keeping it running helps keep it clean.
Why act early in Chapmore End
A greasy fan at the discharge can spread grease onto the roof or wall around it. That stains surfaces and can add to the fire risk outside the building, which is one more reason to keep it clean. Rural sites cannot always move to another kitchen or room when something fails.
What you pay reflects the actual work. That is why every job is surveyed first, and the price is agreed before any work starts.

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 photos. Most of the time goes on the work itself, and that takes an hour or two for most single fans. The timing of a visit to Chapmore End is set by you, and the travel is our side of the planning.
- First we locate the fan and agree how it’s safely isolated.
- The fan is isolated so it cannot start while we work.
- Grease is scraped from the impeller blades and the inside of the housing.
- We degrease the fan and housing, taking care around the motor.
- We reassemble, run the fan and photograph the result.
How to prepare
- Allow time for equipment near the work to be turned off and cool down
- Arrange a key holder or contact on site
- Move anything stored near the system
How to get a quote
To help us quote: where the site is, what it is and its opening hours, pictures of the system and any previous report or certificate. Once you have those, call 0345 646 2711 or email us.

Signs you need extract fan cleaning in Chapmore End
Poor filters mean a greasier fan. When filters don’t seal, grease goes straight through to the fan, so the fan takes far more than it should.
Clients typically contact us after spotting something like this:
- A fan motor running hot under a coat of grease
- Burning smells from the fan area
- Fat spreading onto the roof or wall by the fan
- A fan left out of previous cleans
