About our ductwork cleaning in Clapgate
Once air leaves the canopy, it travels through ductwork that most people never see. Grease settles along every metre of it and a fire in the duct can spread through the building. We clean it from the inside, through access panels, to BESA TR19® Grease. The work covers multi-storey ducts, attenuators and access panels, and common reasons people get in touch are duct runs with no cleaning record and sections of duct with no access panels.
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. Access, parking and timings are agreed before the day.
For insurers and inspectors, the record counts. So every job comes with a written report and photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Managing agents and facilities teams in Clapgate
Multi-site operators often want one contractor and one number. We cover South East England and London, so a run of sites can go into one programme and kept on a regular cycle.
For anyone managing more than one site, we can schedule visits across all of them on one quote. Every building has its own written report, so each one has its own record.
How we price ductwork cleaning
A fixed price needs a few facts first. We check:
- A single visit or a regular plan
- Whether we need access equipment or extra panels
- How many systems or sites are involved
- Site requirements such as sign-in and permits
The cost depends on how big the system is, what state it’s in and access to every part of it. You get a fixed price before we start, so you know where you stand.
What to send for a quote
You don’t need the technical terms. It helps if you can send:
- Any access panels or hatches you can see
- Your opening hours and when the area is out of use
- How we’d reach plant on a roof or in a plant room
- Problems your staff have spotted
Need a price for ductwork cleaning? Please give us a ring on 0345 646 2711 or use the quote form and tell us about the site. We’ll explain what we’d do and send a fixed quote before anything is booked.
Staff cleaning versus specialist work
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We will take a look and send you a fixed quote.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
Kitchen extracts in Clapgate
Clapgate is covered by Hertfordshire 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. Clapgate, about 29 miles from central London, is within our usual area. Evening, overnight and weekend visits are all possible.
A hospital like Herts and Essex Hospital, about 4.2 miles south-east, is the kind of site where a kitchen may cook for patients, staff and visitors all day. Term dates shape school work: for a school like Albury Church of England Voluntary Aided Primary School, an extract clean fits neatly into a half-term or summer break. If you run catering at a historic house or estate in the area (Much Hadham Palace is about 3.4 miles south), event kitchens in older buildings often have awkward duct runs that need planning.
Clapgate is about 4 miles north-west of Bishop's Stortford, in Hertfordshire.

Landmarks near Clapgate
Around Clapgate, our work takes us to kitchens and buildings near The Catherine Wheel pub and the streets around them. The closest station to Clapgate is Bishops Stortford station, roughly 3.9 miles south-east of the centre. Nearby you’ll also find Moated mound (1.2 miles south-east) and Herts and Essex Hospital (4.2 miles south-east). Green spaces nearby include Rushy Mead.
Aftercare tips
Here’s the after-treatment advice, in brief:
- Keep access panels clear of stored items
- Tell us if grease leaks from the ductwork
- Run the extract fan throughout service
- File each certificate and photo report in the maintenance log
The report names every part of the duct that couldn’t be reached, with the reason. You can then decide whether to have access panels fitted.
Keep to the cleaning interval on the report. A change in cooking hours may change the interval under BESA guidance, and grease thickness testing will show it.
Clapgate questions
Do you cover smaller places like Clapgate?
Yes, Clapgate is part of our area, however small the site. Let us know about access, parking and anything unusual about getting there when you book.
Which environmental health team covers Clapgate?
Food hygiene inspections in Clapgate are carried out by East Hertfordshire council. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
Which kinds of sites do you work on?
Any commercial site with kitchens or ventilation, from a small pub to a hospital. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
What if parts of the system cannot be reached?
We record them on the report, with photos where possible, and we tell you what would make it reachable, for example new access panels.
Can you quote from photos?
In many cases, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Where we cannot see enough, we arrange a survey.
Do you install duct access panels?
Yes, as part of our fits and repairs work. We place them where they help most, and we will recommend where.
How is kitchen extract ductwork cleaned?
Each section is cleaned through its own panel. Grease is scraped out first, then degreased, with readings taken before and after.
How can I tell if my extract ducts are dirty?
Drips, smells and weak extraction are clues, but measuring is the reliable way to know. Grease thickness testing shows exactly where the duct stands.
How it works
We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that is an evening, overnight or a weekend. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes a few hours for a short run, longer for long runs and tall risers. Somewhere as small as Clapgate, the date and timings are agreed with you well before the day.
- The duct route is surveyed and every access point found.
- Grease thickness is measured at set points.
- Once the kitchen has closed, we protect the area and open the panels.
- Thick grease is scraped out, then the runs and risers are degreased.
- We close up, re-test, photograph and record anything out of reach.
Before we arrive
- Make sure equipment near the work can be switched off and left to cool
- Tell us about site rules, permits or sign-in
- Have your last certificate or report to hand
How to get a quote

Related advice
Leave it or put it right?
Insurers know the risk of a greasy duct. Many require cleaning to TR19, and they can refuse or reduce a claim without proof. A certificate that covers the ductwork is what they want to see. Rural sites cannot always move to another kitchen or room when something fails.
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you are unsure, phone us on 0345 646 2711 or drop us a line and we will give you an honest view and a fixed quote.

Part by part
Access panels
After cleaning, every panel is closed and sealed, so grease and air stay inside the duct. A damaged panel is noted on the report.
Vertical risers
A riser takes the duct up through one or more floors. Grease runs down the walls and gathers at the base, which is one of the points we test.
