- Stale grease odours from the duct
Ductwork cleaning for kitchens and businesses in Kingsash
Not every duct has enough access panels. TR19 calls for any section we couldn’t reach to be recorded, and new panels can be fitted to reach it in future. It’s better to know than to assume. If you have readings above 200 microns from a grease thickness test and a duct nobody has opened in years, we can help, from access panels, horizontal duct runs and vertical risers onwards.
Work in a small place like Kingsash starts with a call to agree access and timings, and the clean itself is the same full TR19® job as in any town: canopy to discharge, then a TR19® certificate and a photo report.
Accreditations are easy to claim and worth checking. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

In-house cleaning or a specialist?
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.
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, which is where we come in.
Multi-site and managed buildings
We work for landlords, managing agents and facilities managers as well as the people running the site. 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.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
Leave it or put it right?
There’s no law that names TR19. The Fire Safety Order 2005 makes the responsible person assess and reduce fire risk, including the grease inside the extract ductwork. Equipment tucked in a roof space or outbuilding near Kingsash rarely gets looked at unless someone books it.
Every site is different, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all play a part.

What else we do in Kingsash
Ductwork cleaning in Kingsash: the local picture
The Food Standards Agency lists about 4 bars, pubs and nightclubs as registered food businesses in and around Kingsash, up to about a mile and a half out. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. Food hygiene inspections in Kingsash are the job of Buckinghamshire council’s environmental health team. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Keeping each certificate and photo report on file helps show the extract is looked after. Kingsash sits within the area of Buckinghamshire 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.
Cholesbury Manor House, about 2.7 miles east, is one of the historic houses near Kingsash; if you run event catering at a venue like that, cleans can be booked between functions. If you look after a school kitchen, at a school such as Wendover House School or anywhere near Kingsash, the holidays are the usual time for a TR19® clean. Healthcare kitchens, like those at hospitals such as Chiltern Hospital (about 3.7 miles south), often cook for long hours, which puts them in BESA’s heavier-use bands.
Kingsash is about 5 miles north-west of Chesham, in Buckinghamshire. We provide ductwork cleaning for commercial premises of every kind in Kingsash and the rest of Buckinghamshire.

Questions from Kingsash
Do you cover smaller places like Kingsash?
Yes, we work in villages as well as towns, and Kingsash is covered. A survey first, from photos or a visit, means we arrive with the right kit.
Which fire authority looks after Kingsash?
Fire safety enforcement in Kingsash is handled by Buckinghamshire Fire and Rescue Service. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
How much notice should we give?
It depends on the time you need and how big the job is. Mention your preferred dates with your enquiry, and if it’s an emergency, call us any time.
How long does ductwork cleaning take?
It takes a few hours for a short run, longer for long runs and tall risers. The survey tells us how long your duct needs.
How can I tell if my extract ducts are dirty?
A grease thickness test gives the answer. Readings are taken by Wet Film Thickness Test (WFTT) or Deposit Thickness Test (DTT). A mean above 200 microns, or 500 microns at any point, means it’s due.
What accreditations do you have?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We are fully insured and have been trading since 2009.
What happens if there aren’t enough access panels?
Sections out of reach are written down on the report, in line with TR19. New panels can be fitted to reach them in future.
How do you clean inside the ductwork?
We open each access panel and clean the section it reaches. Heavy grease comes out by hand, and what’s left is degreased, with readings taken before and after.

How it works
Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. All we need from you is clear access and the right equipment switched off.

- 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.

What a clean will not put right
To be straight with you, some problems need a different fix:
- Fire dampers that don’t close (they need testing and remedials)
- A worn-out fan that needs replacing
- Ductwork that was poorly designed
Not sure which it is? You can ring 0345 646 2711, or email photos and we’ll tell you honestly before booking.
What the work covers
- Access panels
- Vertical risers
- Bends and junctions
- Multi-storey ducts
- Attenuators
- Horizontal duct runs
How the job changes from site to site
Access panels
Panels have to seal properly once they’re closed, so grease and air stay inside the duct. A damaged panel is noted on the report.
Vertical risers
In taller buildings, a riser may pass through several floors and fire compartments, so fire dampers may be fitted where it crosses them. Damper testing is a separate service.
