Extract fan cleaning in Roe Green, done properly
Duct Doctor has been cleaning kitchen extract fans since 2009. As a BESCA Vent Hygiene Elite member, we clean to BESA TR19® Grease, with CHAS, SafeContractor and ISO 9001 and full insurance. The work covers centrifugal fans, axial fans and in-line fans, and the jobs we see most are a fan that no longer moves enough air and grease around the motor and its mounts.
Somewhere as small as Roe Green, 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, whatever the size of the place.
A written report with photos follows every visit, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Common problems we fix in Roe Green
A greasy fan in Roe Green is fuel at the end of the duct. A fire in the duct can reach the fan and the grease around it and an overworked motor runs hotter.
Common reasons sites call us are:
- A fan left out of previous cleans
- Grease around the motor and its mounts
- Thick grease on the impeller and casing
- Burning smells from the fan area
School kitchens, at schools like Sandon Junior Mixed and Infant School for example, are typically cleaned in the holidays so no lunches are lost.
What to look for in a quote
- When the next visit should be, and why
- Whether the whole system is included, or only the parts that are easy to reach
- Whether inaccessible sections are listed on the report
- Whether the work can be done while the site is closed

Why act early in Roe Green
Vibration from an unbalanced impeller does not stay small. It wears bearings and mounts and can lead to a breakdown and a kitchen can’t cook safely without extraction. A planned clean beats an emergency. Out of sight is the usual reason a rural system goes too long without attention.
No two sites are the same, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all play a part.
Why Roe Green businesses choose us
- Fixed quotes from a survey or pictures
- Full insurance on every job
- Every job surveyed first

What extract fan cleaning looks like in Roe Green
Kitchens in Roe Green get their food hygiene inspections from North Hertfordshire council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Before-and-after pictures from each clean are a simple way to show the extract is in hand. At about 34 miles from central London, Roe Green sits well inside the area we cover. Evening, overnight and weekend visits are all possible.
Volunteers running a hall kitchen near Church of All Saints, or anywhere in Roe Green, may not know when the extract was last cleaned, and a grease test settles it.

What happens on the day
Everything the job needs comes with us, including protection sheets, the right tools and access kit. All we need from you is clear access and the right equipment switched off. On site, the work takes an hour or two for one fan, longer when it’s hard to reach. A few photos of the system help us make the most of a visit to a place like Roe Green.
- First we check the fan’s condition and how it sounds.
- With the fan isolated, the housing is opened.
- 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
- Tell us where we can park and unload
- Make sure equipment near the work can be switched off and left to cool
- Mention any locked doors, roof access or ceiling voids
Getting a quote
To get a fixed quote, phone us on 0345 646 2711 or drop us a line with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. We normally come back within one working day.
Advice
Aftercare tips
Here’s the after-treatment advice, short and simple:
- Leave a clear route to the fan
- Keep each photo report with the maintenance log
- Make sure the fan is included each time
- Listen for new noises or vibration from the fan
You get before and after photos of the impeller and housing. It lists what was cleaned and anything we couldn’t reach, along with the recommended next clean date.
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.
Questions from Roe Green
Who enforces fire safety at workplaces in Roe Green?
It’s Hertfordshire Fire and Rescue Service, which covers Roe Green. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Who would carry out a food hygiene inspection at a kitchen in Roe Green?
Kitchens in Roe Green are inspected by North Hertfordshire council’s environmental health officers. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
What if parts of the system can’t be reached?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, which we can install.
Do you look at the system first?
Yes. For many sites, pictures and a few details are enough, and larger or hidden systems get a visit.
What happens to the waste?
We contain it and take it with us. Grease, debris and waste water are collected as the work goes on, so it does not spread.
Can one contract cover all our sites?
Yes. You deal with one contact for every site in our area, with visits on a regular schedule.

Size, condition, access and working hours all affect the cost. Call for a fixed quote and we’ll normally reply within one working day.
