How we handle ventilation duct cleaning in Isleworth
Every clean ends with a TR19® certificate and a photo report. The report lists what we cleaned, any sections not reached and a recommended next inspection, giving the ventilation a clean bill of health on paper. Typical jobs include extract ducts clogged with lint and dust and ducts that need a clean before handover, across hospitals and care homes, supply ductwork and grilles and diffusers.
Across London, offices, hotels, schools and healthcare buildings rely on mechanical ventilation, much of it supplied through air handling units on roofs or in basements. In a building in Isleworth, dust and debris build up in the units and ductwork over time, which is what TR19® Air cleaning deals with.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we are 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 staff can safely do
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We’ll take a look and give you a fixed quote.
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.
Common questions in Isleworth
Do you work overnight in Isleworth?
Yes, evening, overnight and weekend work is normal for us. The work in Isleworth can fit around your hours. Just call us on 0345 646 2711 or send us an email with your opening times and we’ll plan around them.
Can you clean school ventilation in Isleworth during the holidays?
Yes, and it’s the easiest time to do it. Food Standards Agency records list about 32 schools, colleges and universities with registered kitchens within about a mile and a half of Isleworth. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Do you have insurance?
Yes, fully. We also hold CHAS and SafeContractor, for sites that check contractor safety.
Which kinds of sites do you work on?
Any commercial site with kitchens or ventilation, from a single café to a large school. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
When should our ventilation next be cleaned?
That varies with the building, the filters and how hard the system works. Inspecting regularly shows when cleaning is needed.
What’s TR19?
A BESA specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not law, but it’s the benchmark.
Will you clean the vents in the rooms?
Yes, together with the ductwork. They show up in the photo report before and after.
How much does ventilation duct cleaning cost in Isleworth?
There’s no set price, as it depends on the job: how big it is, what state it’s in, how we reach it and the working hours. We fix the price before we start.

- Kitchen extract ductwork, which needs a TR19® Grease clean

What the work covers
- Toilet extract systems
- Grilles and diffusers
- Supply ductwork
- Offices and schools
- Hospitals and care homes
- General extract ductwork
The process
On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool before work begins, and floors and nearby surfaces are sheeted. On site, it takes a shift or two for a small system, longer for a whole building. Before any visit in Isleworth, we agree where the van can stop and how equipment reaches the system.
- 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.
Getting ready for the visit
- Let us know when the site is closed or quiet
- Clear the space around the work
- Mention any locked doors, roof access or ceiling voids
Getting a quote
Here’s what helps us quote: the address, the type of site and when it’s open, photos of the system and any previous report or certificate. Once you have those, call 0345 646 2711 or send us an email.

How we price ventilation duct cleaning
Before we fix a price, we need to know a few things. We check:
- The condition of the system
- Whether it’s a one-off visit or part of a schedule
- Whether we need access equipment or extra panels
- The scale of the work
Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered and we will price it together.
What we need to know
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- The site address and the type of premises
- Any previous report or certificate
- The roof, plant room or outside wall the system runs to
- Problems your staff have spotted
The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and we can price many jobs without a visit.
Keeping the system healthy
Simple habits between visits make a real difference. We recommend:
- Keep to the inspection interval in your report
- Report leaks or damp near ceilings and risers
- Make sure nothing is stacked against extract grilles
- Protect the system from construction dust
You get a TR19® certificate and a photo report after the clean. Keep them in the maintenance log, with the date, location and technician recorded.
Protect the system during building work by turning it off or covering the openings.
Do you need ventilation duct cleaning in Isleworth?
Ventilation hygiene often gets left out of planned maintenance. Plant can be well serviced while the ductwork goes untouched for years.
Look out for any of the following:
- Systems missing access panels
- Dirty diffusers dropping dust into rooms
- Rooms that feel airless when the system runs
- Musty smells from the ventilation
If you manage shops or offices close to Isleworth station, a TR19® Air inspection shows whether the ductwork needs cleaning.
