What the work involves, part by part
Grilles and diffusers
Dust marks around grilles can point to dirt further back in the system. We clean the grilles and look at what’s behind them.
Extract ductwork
Extract ducts take air out of toilets, washrooms and general areas. They collect dust, lint and fibres and slowly narrow.
Aftercare tips
Once we have finished, these simple steps help:
- Keep filters changed on time
- Flag any dust coming out of the vents
- Keep vents and grilles clear of shelving and stock
- Book the next inspection on the date the report recommends
Before any works, think about the ducts. Switch it off or cover the grilles while dusty work goes on.
Deal with condensation and leaks near ducts promptly, as wet dust is much harder to clean.
FAQs for Denchworth
Can you work in Denchworth outside opening hours?
Yes, evening, overnight and weekend work is normal for us. It means the site in Denchworth keeps running as normal. When you phone us on 0345 646 2711 or drop us a line, mention when the site is quiet.
Can ventilation in schools around Denchworth be cleaned out of term?
Yes. Half-terms and the summer break are the natural time for school work. The FSA’s register shows about 3 schools and colleges with food registrations within roughly a mile and a half of Denchworth. Booking early in the term gives the best choice of holiday dates.
Who is the responsible person?
The Fire Safety Order 2005 calls them the responsible person: often the employer, owner or occupier. Landlords, facilities managers and managing agents can also hold responsibility.
Can you come out in an emergency?
Yes, any time. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line, and we will advise on what to do next.
What if parts of the system can’t be reached?
They’re marked on the report. Often the fix is extra access, such as new panels in ductwork, and we can fit those.
Do you work with multi-site operators?
Yes. Tell us the addresses and what each needs and you will get one fixed quote.
What does TR19 mean?
TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
How far ahead should we book?
The more notice, the better, particularly for night and weekend visits. Quotes usually come back within one working day, and there’s a 24/7 line for emergencies.
What we do, step by step
Protection comes first: floors, worktops and anything near the work are covered. Then we make the system safe and start. The work on site takes from one overnight visit to a phased programme over several weeks, and we clear up before we go. For a village or hamlet like Denchworth, tell us about narrow lanes, gates and parking when you book.
- We start by looking at the layout of the ductwork and how it can be reached.
- Ducts are inspected at access points and the condition recorded.
- We protect the rooms beneath and switch the system off.
- Debris is cleared from the duct runs, then grilles and diffusers are cleaned.
- A certificate and before and after photos follow, with anything not reached recorded.
Getting ready for the visit
- Allow time for equipment near the work to be turned off and cool down
- Name a contact who can let us in at the agreed time
- Move anything stored near the system

Asking for a quote
When you call or email, these details help:
- The times we could work without disrupting the site
- How we’d reach plant on a roof or in a plant room

- Problems your staff have spotted

In-house cleaning or a specialist?
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
