Ductwork cleaning in Chorleywood West
In doctor’s terms, the ductwork is the system’s arteries: find the blockages, clear them, then check the flow is right. Grease readings before and after give you the evidence, alongside before and after photos. We are often asked to deal with duct runs that can’t be reached and high readings at a recent grease test, across multi-storey ducts, attenuators and bends and junctions.
Somewhere as small as Chorleywood West, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Each still has a canopy and duct that collect grease, whatever the size of the place.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

When to call us in Chorleywood West
Grease in a duct running from a kitchen in Chorleywood West is as much a fire risk as in any building. Burning grease can carry fire through the ductwork to other rooms or floors, which is why the responsible person needs it under control.
These are the problems we see most often:
- High readings at a recent grease test
- Thick deposits at the bottom of a vertical duct
- A duct clean needed for an insurer
- Duct runs that cannot be reached
Where a hall near Church of St Peter, or anywhere in Chorleywood West, hosts lunch clubs or events, its extract gathers grease just as a café’s does.
Questions to ask before booking
- Whether a written report and photos are included
- Whether they recommend a next date
- Whether inaccessible sections are listed on the report
- What insurance they carry
How the visit works
There are three stages on the day: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with photos. Most of the time goes on the work itself, which takes from a few hours to more than one visit, depending on duct length and access. We agree a date with you, plan the drive to Chorleywood West and turn up when the site is quiet.
- First we diagnose: the route, the access and the grease levels.
- A fixed quote follows, based on what we found.
- We clean section by section, working from panel to panel.
- We take extra care at bends and at the foot of risers.
- Readings, pictures and a recommended next clean date complete the job.
Before we arrive
- Let us know about parking and loading
- Dig out any earlier paperwork for the system
- Mention any locked doors, roof access or ceiling voids
Ask for a quote
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
Advice
What the work involves, part by part
Attenuators and discharge
Attenuators, where fitted, quieten the extract, but they can hold grease in their linings. We clean what can be reached and note anything that cannot.
Vertical risers
Cleaning a riser needs access along its height. Where it cannot be reached safely, the report says so.

Why it’s worth doing now in Chorleywood West
Dealing with the ductwork in Chorleywood West now beats dealing with it after a problem. It takes from a few hours to more than one visit, depending on duct length and access, and we work evenings, overnight and weekends. Rural sites cannot always move to another kitchen or room when something fails.
What you pay reflects the actual work. That is why every job is surveyed first, and the price is agreed before we start.
What you get with us
- One number for every site across the South East and London
- CHAS and SafeContractor accredited, with ISO 9001
- Ventilation hygiene specialists since 2009
- Full insurance on every job
Take a look at what affects the cost or how to check a contractor.
What affects the cost of ductwork cleaning
A fixed price needs a few facts first. We look at:
- Whether we need access equipment or extra panels
- One-off work versus a regular cycle
- Travel, parking and unloading
- The scale of the work
Combining work into one visit or one programme often makes better use of the time. Mention every system or site you need covered, and you will get one fixed quote.
Asking for a quote
To speed up the quote, send us:
- A few general shots of the system
- Close-ups of filters, grilles, hatches or access panels
- Any previous report or certificate
- When the site is open and when it’s quiet
Getting a quote does not take long. Send a few details and photos, and we normally reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.
Looking after it afterwards
A little care between visits keeps the system in better shape. Our advice:
- Keep grease filters clean and fitted whenever you cook
- Book the next clean before the recommended date
- Check readings when the menu changes
- Keep your cleaning records together
You’ll have a recommended date for the next clean, worked out from the grease we found and how long you cook each day, in line with BESA guidance.
Have access panels fitted where sections can’t be reached. Grease you can reach is grease that gets removed.
Common questions in Chorleywood West
Can you get to a site in Chorleywood West?
Yes. Chorleywood West 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.
Can you clean school kitchen extracts in Chorleywood West during the holidays?
Yes, and it’s the easiest time to do it. Around Chorleywood West, the Food Standards Agency lists about 21 schools and colleges with registered kitchens within a mile and a half or so. You can phone us on 0345 646 2711 or use the quote form with the dates the site is empty.
Do you offer emergency callouts?
Yes, day and night, every day of the year. Office hours are Monday to Friday, 8am to 6pm, with the emergency line covering every other hour.
Is there a survey before the work?
Yes. We always survey first, either from pictures and details you send or on a site visit. Then you get a fixed quote.
What about areas you cannot get to?
They’re listed in the report, never skipped quietly. You will know exactly which parts weren’t reached and why, along with a quote to put access in.
Can you clean ductwork with no access panels?
Any section we cannot reach is recorded on the report, as TR19 expects. New panels can be fitted to reach them in future.
What shows that the ducts need a clean?
We measure it. Readings are taken by Wet Film Thickness Test (WFTT) or Deposit Thickness Test (DTT). BESA guidance says the mean shouldn’t exceed 200 microns, and 500 or more anywhere needs immediate spot cleaning.
Can you price the work without visiting?
Often, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Where we can’t see enough, we arrange a survey.

Food Standards Agency records list about 38 cafés, restaurants and staff canteens and about 20 sandwich bars and takeaways across Chorleywood West and its immediate surroundings (about a mile and a half). Behind every canopy among them is a run of ductwork that collects grease out of sight. Chorleywood West is covered by Hertfordshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.
