Chenies ductwork cleaning
Ductwork cleaning for Chenies, with a survey first and a report with pictures at the end. Call for a fixed quote.
- Duct runs with no cleaning record
- Smells of old cooking grease from the ductwork
- Grease pooling at the foot of the riser
Aftercare tips
How long the results last depends on use and care. We suggest:
- Keep access panels clear of stored items
- File each certificate and photo report in the maintenance log
- Ask for a grease thickness test if the kitchen gets busier
- Book the next clean before the recommended date
Access panels are closed and sealed back up after cleaning, and the area around them is cleaned down. Grease and dirty water are contained and removed.
Some signs mean the duct needs attention sooner: drips from the ductwork, stale smells or a noisy fan. A grease thickness test can confirm whether a spot clean is needed.
Ductwork cleaning in Chenies, done properly
The ductwork is where an extract clean is won or lost. Without enough access panels, long stretches can go years without being touched. We open up every reachable section and record any we cannot reach, so you know exactly where you stand. If you are dealing with gaps where access panels were never fitted and a rancid smell from the extract duct, we can put it right.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, and those horizontal sections are where grease settles. We agree access and timings in advance.
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. It shows what was done and what, if anything, couldn’t be reached.

Different parts, different methods
Bends and transitions
Grease tends to pile up at elbows. It’s scraped out and degreased, and readings are taken there before and after.
Attenuators and discharge
Some systems have attenuators to reduce noise, and their linings can soak up grease. They’re cleaned where possible and recorded if not.
What ductwork cleaning can’t fix
It’s worth knowing the limits before booking:
- Duct sections that need replacing
- A worn-out fan that needs replacing
- Ductwork that was poorly designed

What affects the cost of ductwork cleaning
We quote each job individually. This is what makes a difference:
- Where the site is and how we reach it
- The size of the system
- Whether it’s a one-off visit or part of a schedule
- Site requirements such as sign-in and permits
When the work has to happen, how we reach it and how big the site is all affect the cost. Each of those is built into the quote and give you a fixed price before any work starts.
What to send for a quote
To help us quote quickly, please include:
- Problems your staff have spotted
- The postcode and the type of business
- Your opening hours and when the area is out of use
- Any previous report or certificate
Every quote begins with a look at the system, either from photos and details you send or from a site visit. After that, you get a fixed price for the work so you know the cost before any work starts.
Leave it or put it right?
A dirty duct is something insurers ask about. Many policies require TR19 cleaning, and a claim may be refused or reduced without evidence. Your certificate and photo report show the ducts were cleaned. It’s worth booking a check, because nobody sees inside a duct day to day.
One small site or a whole estate, we price it on the same basis: what needs doing, how we get to it and when. You’ll have a fixed price before we start.

How it works
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left 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. Visits to a village like Chenies are booked in advance, at a time that suits whoever runs the site.
- Diagnosis: a survey of the duct’s route, size and access.
- A fixed quote follows, based on what we found.
- Each section is cleaned in turn through its access panel.
- We take extra care at bends and at the foot of risers.
- The duct is signed off with readings, photos and a next clean date.
How to prepare
- Name a contact who can let us in at the agreed time
- Allow time for equipment near the work to be turned off and cool down
- Have your last certificate or report to hand

Ductwork cleaning in Chenies: the local picture
The FSA’s data shows about 3 pubs, bars and clubs registered within 1.5 miles or so of the middle of Chenies. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Fire safety in Chenies falls to 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. It’s Buckinghamshire council that sends environmental health officers to food businesses in Chenies. 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.
School kitchens, at schools like Chenies School for example, are typically cleaned in the holidays so no lunches are lost. If you run a church or community hall kitchen, near Church of St Michael or elsewhere in Chenies, its extract still collects grease from every lunch and event.

- A duct nobody has opened in years
- Thick deposits at the bottom of a vertical duct
- Grease leaking from duct joints
- Hardened, baked-on grease in long horizontal runs

Chenies questions
Can you come to Chenies after we close?
Yes, nights and weekends are routine for us. That way a site in Chenies doesn’t have to lose a day’s trading. Let us know the hours you’re closed and we’ll book within them.
Which environmental health team covers Chenies?
That’s Buckinghamshire council, whose environmental health officers carry out food hygiene inspections in Chenies. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.
What do you do to protect the area?
Floors and surfaces near the work are sheeted before work begins, and waste is contained as we go. At the end, the area is cleaned down.
What information do you need?
A short description and a few pictures plus the address and your hours. We will ask for anything else we need.
What does ductwork cleaning cost?
There’s no set price, as it depends on the job: the size of the system, its condition, access and when we can work. You get a fixed price before any work starts.
How do you clean inside the ductwork?
We get into the duct through its access panels. Heavy grease is scraped out by hand, then the surfaces are degreased with a method that suits the deposit, such as degreasers, hot water or steam.
How much notice should we give?
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 for anything urgent, ring our 24/7 emergency line.
What do you do with what you remove?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. We don’t leave it behind.
