Ventilation duct cleaning in Childwick Green
Everyone in the building breathes the air the ventilation brings in. Clean ducts are part of a healthy building, alongside filter changes and AHU maintenance. If you’re dealing with ventilation full of debris from building work and ductwork never cleaned since it was installed, we can put it right, from hospitals and care homes, supply ductwork and toilet extract systems onwards.
Somewhere as small as Childwick Green, ducted ventilation is normally limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
The sign-off is always in writing: a dated report with pictures of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

- Whether we need access equipment or extra panels
- A single visit or a regular plan
- What state the system is in

Childwick Green questions
Can you get to a site in Childwick Green?
Yes, Childwick Green is part of our area, however small the site. The journey is planned ahead, so a few details about the route help.
Can a school’s ventilation in Childwick Green be done out of term time?
Yes. Half-terms and the summer break are the natural time for school work. With about 4 schools and colleges on the FSA’s register within roughly a mile and a half of Childwick Green, it pays to plan holiday dates ahead. Tell us your holiday dates and we will book the visit for when the site is empty.
What does TR19 mean?
TR19® is BESA’s specification for ventilation hygiene. 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?
That depends on the slot you want and the size of the job. Tell us your preferred dates when you ask for a quote, and if it’s an emergency, call us any time.
How do you keep the site clean during the work?
Protection goes down first: floor sheeting and covers over nearby surfaces and equipment. We tidy up and take our waste away before we leave.
Are you insured?
Yes. We’re fully insured, and the details are available on request.
Can you clean without closing the building?
Yes, whenever daytime working isn’t practical. Tell us when the system can be switched off and we’ll plan to that.
Is a quote from photos possible?
Yes, for many jobs. Send a few wide pictures plus close-ups of panels, filters or grilles, and we typically come back within one working day. Some sites still need a visit, and we’ll say so.
Why deal with it now?
Where a building in Childwick Green serves patients, residents or children, putting off ventilation cleaning is hard to justify. Good indoor air starts with a clean system. With notice, the visit to Childwick Green can be fitted around your bookings and events.

Aftercare tips
So the system stays in good health:
- Flag any dust coming out of the vents
- Make sure nothing is stacked against extract grilles
- Wipe grilles and diffusers during routine cleaning
- Switch the ventilation off or cover grilles during dusty building work
You get a TR19® certificate and a photo report after the clean. BESA advises keeping certificates in the maintenance log, with the date, location and technician on record.
Fit access panels where the ductwork can’t be reached. Hidden sections are the ones that get worst.
What your team can do, and what needs us
Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We will take a look and send you a fixed quote.
Common problems we fix in Childwick Green
Moisture in ducts makes dust stick. Where there’s condensation or a leak, dust clings and builds faster, and it becomes harder to remove.
If you notice any of these, it’s worth a diagnosis:
- Ductwork that hasn’t been inspected
- Ductwork never cleaned since it was installed
- Musty smells from the ventilation
- Stuffy rooms and stale air
School buildings such as Townsend Church of England School are normally done in the holidays, so classrooms are not disturbed.
Before booking anyone

- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor

- Whether the price is fixed
