Ductwork cleaning in Chesham Bois
Not sure when the ductwork was last cleaned? Tell us about the system when you phone us on 0345 646 2711 or drop us a line, and a fixed price will follow, usually within one working day. If you are dealing with hardened, baked-on grease in long horizontal runs and heavy grease at the base of a riser, we can help, from attenuators, horizontal duct runs and access panels onwards.
In a smaller place like Chesham Bois, the kitchens with extract systems are more likely to be a pub, a café, a takeaway or a school or care home kitchen than a big restaurant. A kitchen that cooks fewer hours still builds up grease, so the interval is set by hours of use and grease readings.
The paperwork matters as much as the work. You get a written report with pictures after every visit, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

Landlords, agents and facilities managers
We regularly work with managing agents. Send the address, what’s needed and how access works and we’ll come back with a fixed quote.
Running several sites is easier with one contractor. We work across London and the South East, so visits at different addresses can be planned together and kept on a regular cycle.
What we do, step by step
At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. All told, the work takes anything from a few hours to several visits, depending on the length of duct. Because the survey comes first, a visit to Chesham Bois can usually be finished without a second trip.
- The duct route is surveyed and every access point found.
- We take grease readings along the route.
- 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 photos repeated, and unreachable sections recorded.
How to prepare
- Dig out any earlier paperwork for the system
- Arrange a key holder or contact on site
- Let us know about parking and loading

Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, you get a fixed price before any work starts.

Different parts, different methods
Attenuators and discharge
Near the discharge, the air has cooled the most, so it can collect more grease than expected. We include it in the clean and the readings.
Vertical risers
A riser takes the duct up through one or more floors. Grease collects on the walls and at the foot of the riser, so the base is one of our test points.
Common problems we fix in Chesham Bois
Air cools as it moves away from the canopy. As it cools, the grease it carries condenses onto the duct walls, which is why ducts go on gathering grease well beyond the filters.
These are the problems we see most often:
- Duct runs with no cleaning record
- Grease leaking from duct joints
- Hardened, baked-on grease in long horizontal runs
- Sections of duct with no access panels
Bursars and site managers at schools such as Elangeni School tend to book extract cleaning for when the kitchen is empty.
What your quote should include
- Whether inaccessible sections are listed on the report
- What paperwork you get at the end
- When they can work, and whether that is outside your opening hours
- Whether the figure could change on the day
FAQs for Chesham Bois
Can you clean school kitchen extracts in Chesham Bois during the holidays?
Yes, and it’s the easiest time to do it. The FSA’s register shows about 16 schools and colleges with food registrations within roughly a mile and a half of Chesham Bois. You can ring 0345 646 2711, or email photos with the dates the site is empty.
Is Chesham Bois within the area you cover?
Yes. Chesham Bois is within the area we cover across London and the South East. Photos of the system and directions to the site help us plan the visit.
How much does ductwork cleaning cost in Chesham Bois?
It depends on the site, so we quote each one individually. To get one, call 0345 646 2711, or email photos with the site type, opening hours and a few photos.
Do you offer emergency callouts?
Yes. There’s a 24/7 emergency line, for problems that can’t wait. Call us any time and explain what’s happened.
Do you survey before quoting?
Yes, every time. We diagnose before we treat: the survey shows what needs doing and what access we need and the fixed quote is built on it.
What if part of the duct can’t be reached?
We clean everything we can reach and record what we can’t. Fitting extra access panels is the usual answer, and we can do that for you.
What shows that the ducts need a clean?
The date on the last certificate is the first thing to check. No record, or a passed date, means it’s due, and grease readings will confirm how urgent it is.
How often does extract ductwork need cleaning?
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 staff can safely do
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that is where we come in.
Chesham Bois kitchens: local notes
There are about 46 restaurants, cafés and works canteens and about 14 takeaways in Chesham Bois and the streets around it, up to about 1.5 miles out, according to the Food Standards Agency’s register. Each kitchen that cooks under a canopy sends grease-laden air into a duct, where it cools and settles. In Chesham Bois, food businesses are inspected by environmental health officers from Buckinghamshire council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A dated certificate in the maintenance file answers the question before it’s asked. The fire and rescue service for Chesham Bois is Buckinghamshire Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.
A kitchen near Amersham station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval. Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Amersham Hospital is the nearest hospital to Chesham Bois, about 1.7 miles south-west.

What affects the quote in Chesham Bois
Before we fix a price, we need to know a few things. We check:
- The scale of the work
- How many systems or sites are involved
- How easy every part is to reach
- Site rules, permits and inductions
A single site or a whole portfolio, we price it on the same basis: what needs doing, how we get to it and when. You will have a fixed price before work begins.

To help us quote quickly, send us:
- Problems your staff have spotted
