Different parts, different methods
Offices and retail
Refits in commercial space often leave construction dust in the ducts. Cleaning before the new occupants move in makes sense.
Extract ductwork
Toilet and washroom extract can carry moisture as well as dust, so the dust tends to cling. They’re cleaned and their condition recorded.
Ventilation duct cleaning for kitchens and businesses in Harmondsworth
We cover Harmondsworth and the rest of Greater London for ventilation duct cleaning, from offices and schools to hospitals, care homes and shops. Each building gets a survey first and a fixed quote. Typical jobs include ventilation that needs a TR19® Air inspection and musty smells from the ventilation, across offices and schools, supply ductwork and general extract ductwork.
London buildings tend to keep their plant on the roof or below ground, so work in Harmondsworth is often done in the evening or at weekends. Loading and parking are planned with the building first.
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.

What we do, step by step
At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and the same goes into the written report. The visit takes a shift or two for a small system, longer for a whole building. Many London buildings have a managing agent, a security desk or a permit-to-work system, so tell us who to contact in Harmondsworth.
- We agree timings that suit the building, including evenings and weekends.
- Access panels are opened along each run.
- Before pictures are taken and the ducts cleaned section by section.
- We clean the grilles and diffusers and put them back.
- We take after photos and send the certificate and report.
Before we arrive
- Name a contact who can let us in at the agreed time
- Have your last certificate or report to hand
- Move anything stored near the system
How to get a quote
Every quote begins with a look at the system, from your photos and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work, before any work starts.

Why act early in Harmondsworth
Dust in ducts doesn’t go away on its own. The longer it’s left, the more there is to remove, and the more gets blown back into the rooms. Planning ahead in Harmondsworth lets you pick a quiet night rather than lose a busy one.
Several systems or sites on one quote can make for a more efficient booking. Tell us about everything you’d like looked at, and you’ll get one fixed quote.

Harmondsworth buildings and their air
Going by the FSA’s register, there are about 11 schools, colleges and universities, about 7 care, childcare and hospital premises and about 12 hotels and guest houses serving food in Harmondsworth and the streets around it, up to about 1.5 miles out. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. Many London buildings have had their ductwork altered through several fit-outs, so an inspection comes first. For Harmondsworth, the closest hospital is Harlington, roughly 1.4 miles east. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes.
If you run a surgery, dental practice or care home near Harmondsworth, clean ventilation matters as much to you as to a hospital like Harlington (about 1.4 miles east).

Questions from Harmondsworth
Do you work at weekends in Harmondsworth?
Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in Harmondsworth needn’t be disturbed. Just call 0345 646 2711, or email photos with your opening times and we’ll plan around them.
Can parking be tricky for a job in Harmondsworth?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. Working overnight, as we often do in London, usually makes it simpler.
Are you accredited?
We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.
What does ventilation duct cleaning cost?
We do not publish prices, because the cost depends on the job: how big it is, what state it’s in, how we reach it and the working hours. You get a fixed price before we start.
What if there aren’t enough access panels?
We clean what we can reach and note the rest. Extra access panels can solve it, and we can quote for them.
Who is the responsible person?
Under the Regulatory Reform (Fire Safety) Order 2005, it’s the responsible person: often the employer, owner or occupier. Landlords, facilities managers and managing agents can also hold responsibility.
Do you work with multi-site operators?
Yes. We work across South East England and London, so sites at different addresses can be planned together on one programme. Each site gets its own report and photos.
Do you have insurance?
Yes. Duct Doctor is fully insured, and the details are available on request.
Multi-site and managed buildings
We also work for facilities teams across offices, schools and healthcare across Greater London. Larger estates can be phased building by building to keep disruption down.
Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.

Also in Harmondsworth
Do you need ventilation duct cleaning in Harmondsworth?
Ductwork is hidden above ceilings and in risers, so nobody sees the build-up. Grilles may be wiped, but the ducts behind them rarely are.
Any of these means the system needs a check-up:
- Supply ducts with years of dust inside
- Toilet and washroom extracts full of fluff
- Ducts that need a clean before handover
- Systems missing access panels
If you manage a school such as Harmondsworth Primary School, ventilation cleaning is best booked for the holidays.

Staff cleaning versus specialist work
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
