Ventilation duct cleaning in Greenhill, Greater London
Ventilation duct cleaning across Greenhill and nearby, timed so the site keeps working and signed off in writing with pictures.

- Systems with no record of inspection or cleaning
- Systems missing access panels
In-house cleaning or a specialist?
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. Reaching it takes a specialist with the right equipment.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.
About our ventilation duct cleaning in Greenhill
Ductwork is reached through access panels along each run. If some sections cannot be reached, the report says so, and we can fit new panels so they’re covered next time. The work covers general extract ductwork, grilles and diffusers and offices and schools, and the jobs we see most are odours carried round the building by the ducts and extract ducts clogged with lint and dust.
London offices and flats often have ductwork added through successive refits, with old runs left behind that are hard to reach. In Greenhill, as elsewhere, cleaning starts with an inspection of what’s there.
The sign-off is always in writing: a dated report with photos of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

Aftercare tips
Simple habits between visits make a real difference. We recommend:
- Keep to the inspection interval in your report
- Do not block grilles with furniture or storage
- Get leaks near ductwork fixed quickly
- Keep the TR19 certificate and photo report in the maintenance log
Keep up with filter changes to protect the ducts. Overdue filters are the quickest way to undo a duct clean.
Make sure there are enough access panels to inspect and clean the ducts. Hidden sections are the ones that get worst.
Do you need ventilation duct cleaning in Greenhill?
Many systems run for long hours, day after day, and every hour moves more dust through the ducts. Heavier use means faster build-up.
The symptoms we are asked about most include:
- Dirty diffusers dropping dust into rooms
- Extract ducts clogged with lint and dust
- Construction dust left in ducts after a refit
- Ductwork never cleaned since it was installed
For workplaces around Hampstead Heath station with mechanical ventilation, cleaning can be done in the evening or at weekends.

Part by part
Offices and retail
Multi-let buildings may share ductwork between tenants. Access is agreed with the building manager.
Hospitals and care homes
Dust control matters during work in occupied care settings. We protect the work area and take everything away.
Why it’s worth doing now in Greenhill
After building work, cleaning the ventilation before people move back in makes sense. Otherwise construction dust left in the ducts is blown out once the system runs. Every month a London system goes without attention adds to what has to be done later.
When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account and give you a fixed price before we start.

Greenhill: your questions answered
Is parking a problem for work in Greenhill?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Working overnight, as we often do in London, typically makes it simpler.
Do you clean school ventilation in Greenhill in the holidays?
Yes. Half-terms and the summer break are the natural time for school work. There are about 69 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Greenhill. Booking early in the term gives the best choice of holiday dates.
How does TR19 Air differ from TR19 Grease?
TR19® Air deals with general ventilation, while TR19® Grease deals with kitchen extract. TR19® Air takes an inspection-led, risk-based approach.
Are you fully insured?
Yes, we are fully insured. CHAS and SafeContractor accreditation sit alongside it, for sites that check contractor safety.
Can you look after several sites?
Yes. We work across South East England and London, so sites at different addresses can be planned together as one programme. Every site has its own report.
What happens if you can’t reach some of it?
We never leave them off the paperwork. The report says which parts couldn’t be reached and why, along with a quote to put access in.
Can you set up regular visits?
Yes. Scheduled maintenance plans are part of what we do, with visits at the interval your system needs. The report from each visit recommends the next date.
Is there a survey before the work?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
