Ventilation duct cleaning in Harefield, Buckinghamshire
Ventilation duct cleaning in Harefield from ventilation hygiene specialists trading since 2009. Out-of-hours visits and 24/7 emergency callout.
- Poor airflow from the vents
- Ducts that need a clean before handover
- Musty smells from the ventilation
What staff can safely do
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.
Ventilation duct cleaning in Harefield, done properly
Every ventilation system has ducts bringing air in and ducts taking it out. Dust and debris build up in both, some of which ends up back in the rooms. We clean the ductwork, grilles and diffusers to TR19® Air. Common call-outs are for odours carried round the building by the ducts and grilles and diffusers streaked with dirt, on grilles and diffusers, hospitals and care homes and toilet extract systems.
In a place like Harefield, air handling units are often tucked into roof spaces or small plant rooms, out of sight and easy to overlook. Every unit, large or small, has filters, coils and a drain tray to keep clean.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

Common problems we fix in Harefield
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.
Signs it’s time to call us include:
- Ductwork that hasn’t been inspected
- Dusty supply ductwork that hasn’t been cleaned in years
- Toilet and washroom extracts full of fluff
- Ventilation full of debris from building work
School buildings such as Harefield Infant School are normally done in the holidays, so classrooms aren’t disturbed.
Before booking anyone
- Whether the whole system is included, or only the parts that are easy to reach
- Which accreditations they hold, and whether you can check them
- How areas they can’t reach will be recorded
- Whether a survey comes first
How it works
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes anything from a single shift for a small office to a planned programme of nights for a large building. For a place like Harefield, we load the van from the survey notes so the work can be done in one visit where possible.
- First we check the layout and any past paperwork.
- Inspection points are chosen and the ducts examined.
- We cover the area below and turn off the system.
- Ducts, grilles and diffusers are cleaned and the debris taken away.
- The report records what was cleaned, anything not reached and a next inspection date.
How to prepare
- Make sure equipment near the work can be switched off and left to cool
- Tell us where we can park and unload
- Have your last certificate or report to hand

Part by part
Extract ductwork
Toilet and washroom extract can carry moisture as well as dust, so the dust tends to cling. We clean them and note any damp or corrosion.
Hospitals and care homes
In healthcare and care settings, there’s no quiet time. The work is sequenced with staff to keep disruption down.
Common questions in Harefield
Can ventilation in schools around Harefield be cleaned out of term?
Yes, holiday work suits schools best. The FSA’s register shows about 4 schools and colleges with food registrations within roughly a mile and a half of Harefield. You can phone us on 0345 646 2711, or email photos with the dates the site is empty.
Do you work at weekends in Harefield?
Yes, evening, overnight and weekend work is normal for us. It means the site in Harefield keeps running as normal. Just ring 0345 646 2711, or email photos with your opening times and we will plan around them.
What does ventilation duct cleaning cost?
Every site is different, so each gets its own fixed quote. To get one, call us on 0345 646 2711 or email us and tell us about the site and its opening hours.
Can you look after several sites?
Yes. One number covers all your sites across London and the South East, and visits can be set on a regular cycle.
Who is the responsible person?
It depends on the building. Under the Fire Safety Order 2005, it’s the responsible person, which can be the employer, the owner, a landlord, an FM or a managing agent.
What does TR19 Air cover?
The two cover different systems: general ventilation for TR19® Air and kitchen extract for TR19® Grease. Under TR19® Air, inspection decides when cleaning is needed.
Is TR19 cleaning required by law?
No. TR19® itself isn’t law; it’s a BESA specification. The legal duty comes from the Regulatory Reform (Fire Safety) Order 2005: the responsible person must assess and reduce fire risk, and TR19® is the benchmark for showing that grease in the extract is under control.
What accreditations do you have?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We’re fully insured and have been trading since 2009.
Honest limits
In fairness, some problems need a different fix:
- Ventilation that is undersized for the building
- Ducts that are damaged, corroded or leaking and need replacing
- Controls and BMS faults that affect the system
If in doubt, call 0345 646 2711 or use the quote form and we will say what we think.
What the work covers
- Supply ductwork
- Hospitals and care homes
- Toilet extract systems
- Offices and schools
- General extract ductwork
- Grilles and diffusers
Landlords, agents and facilities managers
Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept to a regular schedule.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. 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.
What happens if it’s left?
Clean ducts let the air move as designed, which takes strain off the fans. Dirty ducts make the whole system work harder. Around Harefield, a kitchen or building out of action is missed right away.
Working hours, access and the scale of the site all affect the cost. We take each of them into account and give you a fixed price before any work starts.
