Ductwork cleaning in Chalfont St Giles
Duct Doctor has cleaned kitchen extract ductwork since 2009, working across London and the South East. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and our certificates are issued through the BESCA Vent Hygiene Elite portal. If you have duct runs that can’t be reached and thick crusts of old grease along the duct, we can put it right, from attenuators, vertical risers and access panels onwards.
In a smaller place like Chalfont St Giles, many kitchens sit in older buildings or later extensions, where the duct may cross a roof void or climb an outside wall. Flat runs collect grease and need proper access to clean.
Accreditations are easy to claim and worth checking. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

What the work involves, part by part
Horizontal duct runs
A long flat run cannot be cleaned from one end. Any stretch out of reach is noted and can fit extra panels.
Multi-storey and shared buildings
Long ducts in larger buildings can mean several visits. We agree a sequence that suits the building, out of hours where possible.
For landlords and multi-site operators
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we are happy to quote for all of it.
We also work for facilities teams across offices, schools and healthcare in Chalfont St Giles and across Buckinghamshire. Work can be phased by floor, building or site to keep disruption down.
Common problems we fix in Chalfont St Giles
A greasy duct is a fire path, in Chalfont St Giles as anywhere. Burning grease can carry fire through the ductwork to other rooms or floors, which is why the responsible person needs it under control.
Keep an eye out for any of the following:
- A rancid smell from the extract duct
- Thick crusts of old grease along the duct
- Grease leaking from duct joints
- Sections of duct with no access panels
School kitchens, at schools like Chalfont St Giles Infant School and Nursery for example, are usually cleaned in the holidays so no lunches are lost.
Questions to ask before you book

- What’s included in the scope, part by part
- Which accreditations they hold, and whether you can check them
Chalfont St Giles kitchens: local notes
There are about 8 restaurants, cafés and works canteens within 1.5 miles or so of the middle of Chalfont St Giles, according to the Food Standards Agency’s register. Where they cook under a canopy, grease does not stop at the filters: it settles along the duct and up the riser.

Before-and-after photos from each clean are a simple way to show the extract is in hand. Chalfont St Giles sits within the area of Buckinghamshire Fire and Rescue Service.

What staff can safely do
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
What happens on the day
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool first, and floors and nearby surfaces are sheeted. On site, it takes a few hours for a short run, longer for long runs and tall risers. For a site near Chalfont St Giles, the work is booked around your opening hours, evenings and weekends included.
- We trace the duct and find every way in.
- Grease thickness is measured at set points.
- Once the kitchen has closed, we protect the area and open the panels.
- Heavy deposits come out by hand, then each section is degreased.
- Panels are closed, readings and pictures repeated, and unreachable sections recorded.
Preparing for the visit
- Make sure someone can let us in and lock up afterwards
- Make sure equipment near the work can be switched off and left to cool
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas

Advice
Honest limits
We’ll always give you a straight diagnosis, so here’s what this work can’t put right:
- Duct sections that need replacing
- Fire dampers that don’t close (they need testing and remedials)
- Sections that can’t be reached safely without new access (those are recorded, and panels can be fitted)
Not sure which it is? You can phone us on 0345 646 2711 or send us an email and we’ll tell you honestly.
Where we work
- Vertical risers
- Multi-storey ducts
- Access panels
- Horizontal duct runs
- Bends and junctions
- Attenuators
Between visits
A little care between visits keeps the system in better shape. We recommend:
- Book the next clean before the recommended date
- Keep your cleaning records together
- Make sure filters are seated properly
- Tell us if grease leaks from the ductwork
Grease readings are taken again at the same set points, so the report shows the before and after figures. Before and after pictures sit next to the numbers.
Have access panels fitted where sections can’t be reached. Grease you can reach is grease that gets removed.
Questions from Chalfont St Giles
Do you do school kitchen extract cleaning in Chalfont St Giles in the summer holidays?
Yes, out-of-term visits are normal for schools. With about 5 schools and colleges on the FSA’s register within roughly a mile and a half of Chalfont St Giles, it pays to plan holiday dates ahead. You can give us a ring on 0345 646 2711, or email photos with the dates the site is empty.
Who carries out food hygiene inspections in Chalfont St Giles?
That is Buckinghamshire council, whose environmental health officers carry out food hygiene inspections in Chalfont St Giles. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
Where does the waste go?
It leaves the site with us at the end of the visit. While we work, it’s kept contained so the area stays clean.
How much notice do you need?
That depends on the slot you want and the size of the job. Tell us your preferred dates when you ask for a quote, and if it’s an emergency, call us any time.
What’s the cleaning interval for extract ductwork?
It depends mostly on daily cooking hours. Kitchens cooking 12 to 16 hours a day need it at least every 3 months, while lighter use can go longer.
What should I send you?
Only a few details: where it is, what kind of site, when it’s open and the access. Photos and any previous paperwork make it quicker. After that, simply phone us on 0345 646 2711, or email photos.
Can you quote from photos?
Often, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Larger or hidden systems need a survey on site first.
Which sectors do you work in?
Any commercial site with kitchens or ventilation, from a small pub to a hospital. We work with hotels, schools, care homes, offices, retail and leisure sites.
