How it works
Each visit runs to the same pattern: sheeting and protection first, make the system safe, do the work, clear away and leave you the report. The visit itself takes anything from a few hours to several visits, depending on the length of duct. Because the survey comes first, a visit to Chorleywood can normally be finished without a second trip.
- We start by working out how the duct runs and where it can be opened.
- We measure grease thickness at set points before cleaning.
- We open the panels and scrape out the heaviest grease.
- Next the ducts and risers are degreased, using whatever suits the deposit.
- Post-clean readings and pictures go into the report, with any unreachable section listed.
How to prepare
- Let us know about parking and loading
- Tell us about site rules, permits or sign-in
- Let us know when the site is closed or quiet
How to get a quote
Quotes are quick. Send a few details and photos, and we usually reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.

Ductwork cleaning in Chorleywood
We treat ductwork like a doctor treats arteries: diagnose where grease has built up, clear it and confirm the result. Readings taken before and after show the difference, alongside before and after pictures. The work covers bends and junctions, horizontal duct runs and multi-storey ducts, and common reasons people get in touch are a rancid smell from the extract duct and duct runs with no cleaning record.
For a smaller kitchen near Chorleywood, a TR19® clean is the same job as anywhere: canopy, filters, plenum, duct, fan and discharge. We plan the visit around your hours, with the journey sorted in advance.
Each visit ends with a written report and pictures, 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.

What happens if it’s left?
A partly blocked duct slows the airflow. The fan works harder, the kitchen gets hotter and smoke lingers at the canopy, and grease may start to leak from joints. Light use slows the build-up but does not stop it.
The cost depends on how big the system is, the condition it’s in and how easy it is to reach. You get a fixed price before any work starts, so you know where you stand.

Different parts, different methods
Bends and transitions
A bend can hold far more grease than a straight run of the same length. It’s scraped out and degreased, and readings are taken there before and after.
Multi-storey and shared buildings
In a shared building, the duct links the kitchen to other spaces, which makes keeping it clean all the more important. Your certificate and report give building managers the record they need.
What a clean won’t put right
We’ll always give you a straight diagnosis, so here’s what ductwork cleaning won’t do:
- A worn-out fan that needs replacing
- Ductwork that’s corroded, split or holed (that needs a ductwork contractor)
- A duct that is too small or badly routed for the kitchen (a design issue)
If in doubt, call 0345 646 2711 or email us and we will say what we think before you book.

Aftercare tips
Aftercare is simple, and it makes the next visit easier:
- Keep the fan on while anything is cooking
- Report any grease dripping from duct joints
- Keep to the interval on the report
- Keep your cleaning records together
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.
Have access panels fitted where sections cannot be reached. Grease you can reach is grease that gets removed.
Chorleywood questions
Do you work overnight in Chorleywood?
Yes, nights and weekends are routine for us. It means the site in Chorleywood keeps running as normal. Just call us on 0345 646 2711 or send us an email with your opening times and we’ll plan around them.
Will you come out to Chorleywood?
Yes, we work in villages as well as towns, and Chorleywood is covered. A survey first, from pictures or a visit, means we arrive with the right kit.
Do we need to close while you work?
Not usually. We need the work area to ourselves while we are on site, so we book a time when it would be closed anyway.
How do you know if the ductwork needs cleaning?
Signs include grease dripping from joints, smells and a fan working harder, but the only sure way is to measure. Grease thickness testing shows exactly where the duct stands.
What’s TR19?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Which kinds of sites do you work on?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, plus food production and leisure sites.
What happens to the waste?
We take it away when we go. While we work, it’s kept contained to keep the area clean.
Can you quote from photos?
In many cases, yes. With good pictures, the site type and your last report, we can price many jobs. Where we can’t see enough, we arrange a survey.
What your team can do, and what needs us
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.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
Grease, kitchens and Chorleywood
Food Standards Agency records list about 32 restaurants, cafés and canteens and about 14 takeaways within about 1.5 miles of central Chorleywood. The duct above a busy canopy coats itself in grease long before anyone sees it. It’s Three Rivers council that sends environmental health officers to food businesses in Chorleywood. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Our report lists what was cleaned and when, which is useful to have ready. Chorleywood sits within the area of Hertfordshire Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
Volunteers running a hall kitchen near Christ Church, or anywhere in Chorleywood, may not know when the extract was last cleaned, and a grease test settles it. Term dates shape school work: for a school like Christ Church Chorleywood CofE School, an extract clean fits neatly into a half-term or summer break. A kitchen near Chorleywood station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval.

Multi-site operators often want one contractor and one number. We cover South East England and London, so visits at different addresses can be planned together and kept on a regular cycle.
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 can quote for the whole system.
