What affects the cost of ductwork cleaning
Every site gets its own quote. These are the things that affect it:
- The number of sites or systems
- Site rules, permits and inductions
- The size of the system
- A single visit or a regular plan
What you pay reflects the actual work. That’s why every job is surveyed first, and the price is agreed before work begins.
What we need to know
There’s no need for technical detail. Just send:
- The site address and the type of premises
- Any symptoms, from odd noises to smells or leaks
- Photos showing the whole system and its surroundings
- How we’d reach plant on a roof or in a plant room
To help us quote: the address, the type of site and when it’s open, a few pictures and the last certificate or report, if there is one. Once you have those, phone us on 0345 646 2711, or send details by email.
Ductwork cleaning in Kings Langley, done properly
Each extract duct we take on in Kings Langley goes through the full routine: readings at set points, heavy grease scraped out by hand, then degreasing to suit the deposit. Post-clean readings and pictures complete the record. If you have grease seeping out of the duct seams and a grease test showing the duct is overdue, we can help, from multi-storey ducts, access panels and vertical risers onwards.
For a smaller kitchen near Kings Langley, a TR19® clean is the same job as anywhere: canopy, filters, plenum, duct, fan and discharge. The visit is booked around your opening hours, and the journey is planned ahead.
Insurers, fire officers and environmental health officers all look at records. That is why every job is written up in a report with photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Other services in Kings Langley
Part by part
Attenuators and discharge
Attenuators, where fitted, quieten the extract, and their linings can soak up grease. They’re cleaned where possible and recorded if not.
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. The paperwork suits landlords and managing agents.
Signs you need ductwork cleaning in Kings Langley
A vertical riser can run up several floors. Grease clings to the walls and can run down to the base, where it can pool. Access along its height is needed to clean it properly.
Look out for these warning signs:
- A duct clean needed for an insurer
- Gaps where access panels were never fitted
- Heavy grease at the base of a riser
- A duct nobody has opened in years
A kitchen near Kings Langley station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval.

What staff can safely do
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.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We can diagnose it and quote.

Common questions in Kings Langley
Can you get to a site in Kings Langley?
Yes. Villages and rural sites across the South East are part of our work, Kings Langley included. The journey is planned ahead, so a few details about the route help.
Do you clean school canteen extracts around Kings Langley out of term?
Yes, and it’s the easiest time to do it. There are about 7 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Kings Langley. Send us your term dates when you call 0345 646 2711, or send details by email, and we will fit the work in.
Are you fully insured?
Yes. Full insurance covers our work and have been trading since 2009.
How do you know if the ductwork needs cleaning?
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 long does it take to clean extract ducts?
Short runs are quick, but long or complex ducts may take several visits. Visits are planned out of hours.
What’s the cleaning interval for extract ductwork?
The duct is cleaned as part of the whole system, at intervals set by BESA guidance, ranging from 3-monthly to 12-monthly. Readings tell you if it needs to be more often.
What do you do with what you remove?
It leaves the site with us at the end of the visit. During the work, it’s contained to keep the area clean.
What if part of the duct cannot be reached?
Any section we cannot reach is recorded on the report, in line with TR19. We can fit new access panels so they’re cleaned next time.

In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.

Everything the job needs comes with us, including protection sheets, the right tools and access kit. You only need to give us clear access and switch off what needs to be off. On site, the work takes anything from a few hours to several visits, depending on the length of duct. For a place like Kings Langley, we load the van from the survey notes so the work can be done in one visit where possible.
- We trace the duct and find every way in.
- We take grease readings along the route.
- 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.
How to prepare
- Tell us about site rules, permits or sign-in
- Move anything stored near the system
