How we handle ventilation duct cleaning in Cranford
Beyond the kitchen, TR19® Air covers the ordinary supply and extract systems that serve offices, schools and other buildings. It works by inspecting first and cleaning where the risk calls for it, so we look before we clean. If you’re dealing with odours carried round the building by the ducts and rooms that feel airless when the system runs, we can put it right, from grilles and diffusers, hospitals and care homes and offices and schools onwards.
Many London buildings have had their ventilation extended and altered through several fit-outs, leaving sections that are hard to reach and seldom cleaned. An inspection first shows where cleaning is needed in a building in Cranford.
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 are fully insured.

How it works
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so a kitchen or building can carry on as usual the next day. On site, the work takes a shift or two for a small system, longer for a whole building. In Cranford, as across London, we typically work overnight or at weekends and hand the site back ready to open.
- We agree timings that suit the building, including evenings and weekends.
- Access panels are opened along each run.
- Before photos are taken and the ducts cleaned section by section.
- Grilles and diffusers are cleaned and refitted.
- We take after photos and send the certificate and report.
Before we arrive
- Tell us where we can park and unload
- Mention any sign-in, permit or induction we need
- Let us know when the site is closed or quiet
How to get a quote
Every quote begins with a look at the system, either from photos and details you send or from a site visit. After that, you get a fixed price for the work, before work begins.

Why act early in Cranford
Where a building in Cranford serves patients, residents or children, putting off ventilation cleaning is hard to justify. Clean ducts are part of providing good air for the people inside. For a site in Cranford, fitting the work in overnight now is far easier than closing at short notice later.
You will not find a price list here, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll talk you through it.

What the work involves, part by part
Schools and colleges
Holidays and weekends are the natural time to clean school ventilation, with nobody in the classrooms.
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.
Cranford buildings and their air
Going by the FSA’s register, there are about 22 schools, colleges and universities, about 20 caring premises (care homes, nurseries and hospitals) and about 19 hotels, B&Bs and guest houses serving food within about 1.5 miles of central Cranford. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. Getting kit to a London plant room typically means lifts, stairs and an agreed loading slot. Hounslow Hospital is the nearest hospital, about 1.6 miles east of Cranford. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes.
If you manage a school such as Cranford Primary School, ventilation cleaning is best booked for the holidays.

When to call us in Cranford
Building work is one of the biggest sources of debris in ducts, particularly if it’s left running while work goes on. That dust can stay in the ducts long after the builders leave.
Look out for these warning signs:
- Toilet and washroom extracts full of fluff
- Ductwork never cleaned since it was installed
- Poor airflow from the vents
- Ducts that need a clean before handover
Hounslow Hospital, about 1.6 miles east, is the nearest hospital to Cranford, and healthcare sites of every size need their supply air kept clean.

What your team can do, and what needs us
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that’s where we come in.
Common questions in Cranford
Can you come to Cranford after we close?
Yes. We work evenings, overnight and at weekends. That way a site in Cranford does not have to lose a day’s trading. Let us know the hours you are closed and we will book within them.
Can parking be tricky for a job in Cranford?
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 have a 24/7 line?
Yes. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line and we will talk you through the next steps.
Will we have paperwork to show the system was cleaned?
Yes, a TR19® certificate and pictures. The report lists what was cleaned, anything not reached and the next inspection date.
Are you insured?
Yes. Full insurance covers our work and have been trading since 2009.
What about areas you can’t get to?
We record them on the report, with a note of where it is, and we explain what access is needed, for example new access panels.
When should our ventilation next be cleaned?
It depends on the building, how the system is used and what inspection finds. Inspecting regularly shows when cleaning is needed.
Do you clean grilles and diffusers?
Yes. Removable grilles come down for cleaning and go back up. Fixed ones are cleaned in place.
Looking after it afterwards
After the visit, a few habits help the work last:
- Keep the TR19 certificate and photo report in the maintenance log
- Do not block grilles with furniture or storage
- Report leaks or damp near ceilings and risers
- Keep grilles and diffusers dusted
Change filters on schedule so the clean ducts stay clean. Overdue filters are the quickest way to undo a duct clean.
TR19® Air works through regular inspection. Scheduled inspections spot dust before it becomes a major job.
