Ventilation duct cleaning in Duckett's Green
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. Our cleaning covers the ducts, grilles and diffusers, to TR19® Air. The work covers offices and schools, grilles and diffusers and supply ductwork, and the jobs we see most are dust marks around grilles and ceiling diffusers and toilet and washroom extracts full of fluff.
London offices and flats often have ductwork added through successive refits, with old runs left behind that are hard to reach. In Duckett's Green, as elsewhere, cleaning starts with an inspection of what’s there.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

How the job changes from site to site
Schools and colleges
Classrooms full of people, paper and coats produce plenty of dust. Inspection shows when cleaning is due.
Hospitals and care homes
Hospitals and care homes are occupied day and night. The work is sequenced with staff to keep disruption down.
How it works
Your trading hours come first. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes from one overnight visit to a phased programme over several weeks. Most London sites can’t stop for the day, so work in Duckett's Green is usually done overnight, early in the morning or at weekends.
- First we plan when the work can happen, often out of hours.
- We open the ductwork through its access panels.
- Before photos are taken and the ducts cleaned section by section.
- We clean the grilles and diffusers and put them back.
- After photos are taken and the certificate and report issued.
Preparing for the visit
- Mention any sign-in, permit or induction we need
- Clear loose items from the work area
- Tell us where we can park and unload
How to get a quote
Quoting starts with a diagnosis, from your pictures and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work so you know the cost before work begins.

Going by the FSA’s register, there are about 47 schools, colleges and universities, about 48 care, childcare and hospital premises and about 3 hotels and B&Bs serving food within about 1.5 miles of central Duckett's Green. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. About 1.5 miles north of Duckett's Green is Greentrees Hospital, the nearest hospital. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale. London plant rooms are often on roofs or in basements reached through occupied floors.
If you run a surgery, dental practice or care home near Duckett's Green, clean ventilation matters as much to you as to a hospital like Greentrees Hospital (about 1.5 miles north).

Questions from Duckett's Green
Can you clean school ventilation in Duckett's Green during the holidays?
Yes. Half-terms and the summer break are the natural time for school work. With about 47 schools and colleges on the FSA’s register within roughly a mile and a half of Duckett's Green, it pays to plan holiday dates ahead. Tell us your holiday dates and we’ll book the visit for when the site is empty.
What do you need to know about parking in Duckett's Green?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. If the building has a loading slot system, we’ll book into it.
Do we lose a day’s trading?
Usually not. Booking the work out of hours means the site can carry on as normal. Bigger sites can be done in stages to keep things running.
Can you clean without closing the building?
Yes. The work is planned around the building’s hours. Schools are often done in the holidays and offices out of hours.
Who is responsible for fire safety on the premises?
The law calls them the responsible person. It’s normally the employer, or whoever controls the building, and in shared buildings more than one person can have duties. If you’re not sure, check your lease and fire risk assessment.
Do we get a certificate after the clean?
Yes, both a certificate and a photo report. It also notes unreached sections and a recommended next inspection.
What types of premises do you cover?
Any commercial site with kitchens or ventilation, from a single café to a large school. We work with hotels, schools, care homes, offices, retail and leisure sites.
Can you set up regular visits?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, depending on what the system needs.

What else we do in Duckett's Green
Looking after it afterwards
Good habits slow the build-up between visits. A few tips:
- Keep vents and grilles clear of shelving and stock
- Keep grilles and diffusers dusted
- Protect the system from construction dust
- Diary the next TR19® Air inspection
Share the report with whoever looks after the building’s maintenance, so it’s all in one place. Over time, it shows how quickly the system gets dirty.
Make sure there are enough access panels to inspect and clean the ducts. Hidden sections are the ones that get worst.
Managing agents and facilities teams in Duckett's Green
Multi-site operators often want one contractor and one number. We work across London and the South East, so a run of sites can go into one programme and kept to a regular schedule.
We also work for facilities teams across offices, schools and healthcare across Greater London. Larger estates can be phased building by building around the people who use them.
Common problems we fix in Duckett's Green
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.
Common reasons sites call us are:
- Dusty supply ductwork that hasn’t been cleaned in years
- Grilles and diffusers streaked with dirt
- Extract ducts clogged with lint and dust
- Rooms that feel airless when the system runs
School buildings such as St John Vianney RC Primary School are usually done in the holidays, so classrooms are not disturbed.

Honest limits
Before booking, it helps to know what’s not included:
