TR19 air cleaning of general supply and extract ventilation ductwork in commercial buildings for Stanborough, with a survey first and a report with pictures at the end. Ask us for a fixed quote.
- Grilles and diffusers streaked with dirt
- Duct runs that can’t be reached for cleaning
- Construction dust left in ducts after a refit
Looking after it afterwards
How long the results last depends on use and care. Here’s what we suggest:
- File each ventilation report with the building records
- Diary the next TR19® Air inspection
- Keep vents and grilles clear of shelving and stock
- Switch the ventilation off or cover grilles during dusty building work
Share the report with whoever looks after the building’s maintenance, so it’s all in one place. Year on year, it shows how fast dust builds up.
TR19® Air works through regular inspection. Inspecting on a schedule catches build-up before it becomes a big clean.
Ventilation duct cleaning for kitchens and businesses in Stanborough
We cover Stanborough and the rest of Hertfordshire for ventilation duct cleaning, in offices, schools, healthcare buildings and retail. Every job begins with a survey and a fixed quote. The work covers toilet extract systems, supply ductwork and hospitals and care homes, and the jobs we see most are systems missing access panels and grilles and diffusers streaked with dirt.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.
We have been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.

What we do, step by step
Protection comes first: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. It takes a shift or two for a small system, longer for a whole building, and we clear up before we go. Rural roads and tight entrances are worth telling us about before a visit to Stanborough.
- We start by looking at the layout of the ductwork and how it can be reached.
- Inspection comes next, with pictures of the inside of the ducts.
- Floors and furniture are covered and the ventilation turned off.
- Debris is cleared from the duct runs, then grilles and diffusers are cleaned.
- You get a TR19® certificate and photo report, with any unreached sections noted.
Getting ready for the visit
- Move anything stored near the system
- Find the previous report, if there is one
- Let us know about parking and loading

Part by part
Supply ductwork
We check supply ducts at intervals along each run before deciding what to clean.
Extract ductwork
Washroom extracts handle damp air, so the dust tends to cling. They’re cleaned and their condition recorded.
Do you need ventilation duct cleaning in Stanborough?
Even good filters let some dust through, and that fine dust settles along the supply ducts. Extract ducts collect whatever the rooms give off: dust, fibres and lint.
Most sites get in touch after spotting one of these:
- Duct runs that can’t be reached for cleaning
- Dust marks around grilles and ceiling diffusers
- Toilet and washroom extracts full of fluff
- Ventilation that needs a TR19® Air inspection
Hospitals such as Queen Elizabeth II Hospital (about 1.8 miles east) show how much a building can rely on clean ventilation, and smaller healthcare sites near Stanborough are no different.

What your team can do, and what needs us
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which 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.
Leave it or put it right?
A clean system moves air more easily, which takes strain off the fans. Dirty ducts make the whole system work harder. Equipment tucked in a roof space or outbuilding near Stanborough rarely gets looked at unless someone books it.
The cost depends on how big the system is, what state it’s in and access to every part of it. We give you a fixed price before any work starts, so there are no surprises.

What does TR19 Air cover?
TR19® Air deals with general ventilation, while TR19® Grease deals with kitchen extract. TR19® Air takes an inspection-led, risk-based approach.
What do you do with what you remove?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. We do not leave it behind.
Do we lose a day’s trading?
Not usually. We need the work area to ourselves while we’re on site, so we book a time when it would be closed anyway.
What is TR19?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t legislation, but it’s the standard people check against.
Can you set up regular visits?
Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. The report from each visit recommends the next date.
What a clean will not put right
Before booking, it helps to know what’s not included:
- Ducts that are damaged, corroded or leaking and need replacing
- Building management settings that run the plant
- Leaks from roofs, pipes or walls into the ductwork
