Ventilation duct cleaning in Boxmoor
Inspection comes first. We look inside the ductwork at set points and record what’s there, and cleaning is recommended where the inspection shows it’s due. That way the work matches the real condition. We’re often asked to deal with odours carried round the building by the ducts and rooms that feel airless when the system runs, on grilles and diffusers, general extract ductwork and hospitals and care homes.
In a place like Boxmoor, air handling units are often tucked into roof spaces or small plant rooms, where they’re easy to forget. Every unit, large or small, has filters, coils and a drain tray to keep clean.
Think of the report as the system’s health record: dated, with pictures, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

How the visit works
Your staff don’t need to do much on the day. A contact on site lets us in at the agreed time and points us to the system, and the rest is down to us. Before we leave, the area is tidied and the paperwork follows. In a smaller place like Boxmoor, parking is rarely the issue, but tell us about gates, roof access and opening hours.
- We look at the system and any earlier reports.
- We inspect the ducts at chosen points to see where cleaning is needed.
- The work area is protected and the system switched off.
- We clean the system and remove the debris from site.
- The report records what was cleaned, anything not reached and a next inspection date.
Before we arrive
- Have your last certificate or report to hand
- Mention any locked doors, roof access or ceiling voids
- Allow time for equipment near the work to be turned off and cool down

What your team can do, and what needs us
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Do you need ventilation duct cleaning in Boxmoor?
Even good filters let some dust through, so fine dust settles in supply ductwork over the years. Extract ducts pick up dust, fibres and fluff from the rooms they serve.
It’s time to book a visit if you see:
- Ventilation that needs a TR19® Air inspection
- Duct runs that can’t be reached for cleaning
- Ventilation full of debris from building work
- Ductwork never cleaned since it was installed
If you manage a school such as Boxmoor Primary School, ventilation cleaning is best booked for the holidays.

FAQs for Boxmoor
Do you clean school ventilation in Boxmoor in the holidays?
Yes, and it’s the easiest time to do it. With about 20 schools and colleges on the FSA’s register within roughly a mile and a half of Boxmoor, it pays to plan holiday dates ahead. Just call 0345 646 2711 or email us with your term dates and we’ll plan around them.
Do you work in villages like Boxmoor?
Yes. Boxmoor is within the area we cover across London and the South East. A survey first, from pictures or a visit, means we arrive with the right kit.
Can you set up regular visits?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, depending on what the system needs.
Who has the legal duty for fire safety?
The Fire Safety Order 2005 calls them the responsible person: normally the employer or whoever controls the premises. In shared or managed buildings, a landlord, facilities manager or managing agent can share the duty.
How does TR19 Air differ from TR19 Grease?
It covers ventilation hygiene for supply and extract systems in offices, schools, hospitals and other buildings. Kitchen extract is covered separately, by TR19® Grease.
Do you work with multi-site operators?
Yes. One number covers all your sites across London and the South East, with visits on a regular schedule.
What do you do with what you remove?
We contain it and take it with us. Grease, debris and waste water are collected as the work goes on rather than letting it spread.
Are grilles and diffusers included?
Yes, along with the ducts behind them. You will see them in the before and after pictures.
